Zoysia tenuifolia - Use as Ornamental Grass

Think of zoysia and you think of fine, good looking turf areas. They are seen as an option for replacement of other warm season grasses due to their low maintenance and low fertiliser demands.

But there is another zoysia that offers an alternative for grass cover that really needs no mowing, or well, almost no mowing or cutting!

This option may be well suited to median strips, roundabouts and other areas such as rockeries where the landscaping needs to be very low maintenance. The grass may also be suited to small Japanese gardens, courtyards within commercial buildings, and similar areas. There may be particular options where the species could be well suited to use on green roof developments in the tropics and sub tropics.



It is VERY slow growing, which is both a plus and a minus. Slow growth will certainly be an issue trying to establish an area of the grass, unless there is an adequate supply of plugs, stolons or even established plants used from small pots to give you a high plant density at planting. The slow growth is a virtue once you have it planted though – very low maintenance.






Zoysia tenuifolia – sometimes called no grow grass, slow grow grass, petting grass – usually has a puffy appearance once established, almost like ‘hills and valleys”, which can be quite attractive. It provides extremely high ground cover, with virtually no mowing or cutting required. Leaves are short, and often a little stiff / spikey.

On the other side of the ledger...........when you do need to cut the area, it can look awful, as you tend to expose the deep mat of stolons below the grass surface, showing the cut edges. This cutting is often an annual or biennial event.





It is well suited to tropical and subtropical areas, and maybe on protected sites in warm temperate areas. It is strongly shade tolerant . You occasionally see this grass being sold as “petting grass” for use as an indoor plant.

Low maintenance, low to medium water use, shade tolerant, low growing – medium to high potential for wider ornamental use.

Live Cattle Trade - A Producers View

A lot of words have flowed over the past few weeks on this topic.

The quality of the debate has been extremely partisan, and northern cattle producers feel rather miffed. Most comment against the existing trade has come from southern Australia.

One needs to differentiate the trade in live animals, and their slaughter. Does not seem to have been done by most anti the current practices.

Where were all the gurus offering to build abattoirs and facilites for local north Australia processing over the past 20 years or so so that the animals could be processed here? Talk is cheap.......show me the $$$$ for an abattoir in Darwin, Broome, Wyndham or Kununurra, let alone Karumba in Queensland. NEVER HAPPENED.

There have been more serious discussions over the past 2-4 years, and maybe one will get built.......but not before sometime in 2012. Oh, by the way.........that meat is probably not going to Indonesia anyway.

Read the article by a local NT Cattle producer, about 100kms south of Darwin.

Very poignant and pertinent!

Live Cattle Trade to Indonesia

This issue will NOT disappear, with the WA government now pressuring the Australian government to get it sorted out VERY SOON.

Lots of stories in the various press formats still, and no doubt will continue.

More here...
http://www.theaustralian.com.au/national-affairs/wa-premier-colin-barnett-wants-live-cattle-exports-to-indonesia-resumed/comments-fn59niix-1226081320373

The tenor of the comments particularly from the urban areas indicates little real knowledge of the issue generally.... just that it has to cease.

Some commenters make a case for "structural adjustment" in the northen cattle industry, funded by the government. Sounds fine, but would be monumentally expensive, and take years and years, not to mention a lot of R and D to produce different cattle, better pastures etc. The farms are not factories; cattle are not machines.

In a world needing food the loss of this product in Indonesia is likely to be of dire concern.

Will Indonesia be now as co-operative in dealing with other issues of joint concern - people smuggling, cross border animal and plant disease work, military co-operation. Face needs saving!! And fast......

Live Cattle Exports - Some Real Facts

"During 2006, 99.82% of cattle and 99.1% of sheep that were loaded onto livestock export vessels in Australia arrived in importing countries in good health after being well looked after during the voyage.

These figures represent a positive ongoing result for the Australian livestock export industry, but industry is committed to continuing to improve. That is why industry, with the Australian Government and AQIS, actively invests in initiatives to improve animal welfare."

The data above came from from an Australian website on animal transport care - both in trucks and ships.

Some data being bandied about by the anti livestock export mafia refer to losses around 5%..........that is NOT correct, particularly for short haul cattle exports from northern Australia to SE Asia. The real figures for that trade are probably even less than the 0.2% above.

Australia's Tropical Beef Herd - Methane Emissions Lower Than Current Estimates

New CSIRO research indicates that the amount of methane emitted from cattle fed on tropical grasses in northern Australia is up to 30 per cent less than figures currently used to calculate the northern cattle industry's contribution to Australia's greenhouse gas accounts.

Speaking at a recent Lansdown Field Day near Townsville, Queensland, CSIRO research leader Dr Ed Charmley said the findings would help to refine the nation's greenhouse gas accounting."






Measurements from cattle in CSIRO's custom-built respiration chambers show that Brahman cattle fed a wide range of tropical grasses emit up to 30 per cent less methane than previously determined. "While you always have to be cautious in extending lab data to the field and across an industry, we have been able to cross-check our findings with methane detecting laser systems used in the field."

These findings, while not changing the actual emissions, could have significant implications for calculating the emission footprint of the northern cattle industry and also for Australia's greenhouse gas accounts. "Methods used to determine these national greenhouse gas accounts are regularly reviewed and if the new data are confirmed via this review process, future accounts will be adjusted to reflect the lower emissions for the northern beef herd," Dr Charmley said.

With about half of the nation's beef herd located in northern Australia, current greenhouse gas accounts indicate that methane from the northern cattle industry contributes about 4.5 per cent of Australia's greenhouse gas emissions. As a by-product of digesting plants, ruminant livestock such as sheep and cattle produce methane and, of those, beef cattle produce the most - about 200 grams a day, or about 1.5 tonnes of CO2 equivalents per animal every year."

CSIRO research also shows that northern cattle fed on a diet of predominantly Leucaena, a legume tree, emit less methane than cattle grazing on tropical grasses," Dr Charmley said. "What this nutrition research is showing is that there can be win-win scenarios for the industry and the environment if we can redirect the breakdown of plant material in a way that reduces the amount of methane produced while improving the amount of energy or weight gain that animals get from their feed. "We are addressing cattle methane emissions from several angles - from examining the gut microbes that produce methane from ingested pasture and alternative diets, to a landscape focus on northern Australia's extensive grazing systems using state-of-the-art technologies, such as lasers and wireless sensor networks, to measure and model cattle methane emissions under tropical conditions."

The Lansdown Research Station is a key part of CSIRO's broader research programs on livestock production and emissions reduction in agriculture.

Lansdown Research Station is funded by the Australian Government's Climate Change Research Program, Meat & Livestock Australia and CSIRO and is one of five national research hubs and demonstration sites for practical methane management on-farm.

While this CSIRO press release is encouraging news for the northern beef producers, it is still to be verified in other research.

It seems to also confirm that using higher digestibility forages - in this case leucaena, a legume, it is possible to further lower methane emissions. This is similar to broad results from research work in temperate regions on dairy cows where lowered methane emissions were also corelated strongly with use of higher quality [ digestibility] feed.

There has been a trend in the past 20 years to push for more grass in beef pastures as compared to earlier periods of northern development when pasture legumes were seen as more important - then related to higher protein levels in the diet. Unfortunately, most grass now eaten by stock is on the dry side, with quite low digestibility, especially in more extensive pastoral regions. Changing digestibility can be done through plant breeding, but that is unlikely to happen any time soon. Tropical grasses also tend to be of lower digestibility intrinsically than temperate pasture species.

Leucaena is a viable option in many areas, although getting pasture areas established is time consuming and costly. It does have well proven performance in growing and finishing stock across many regions of north Australia. Superb results were achieved about 25 years ago in the Ord Valley at kununurra, but not too many producers are using the system - why would you, when live export has been the normal practice and there is little bonus for good quality finished cattle, with high carcase quality, in the north of Australia.

Lowered estimated methane emissions might quell some of the wild statements made about how awful the beef herd is environmentally though!

Organic Eggs - NOT ALL Are Really Organic

According to the Cornucopia Institute (CI), a non-profit which promotes economic justice for family scale farming, all organic eggs produced in the USA are not alike.

They recently released the report - Scrambled Eggs: Separating Factory Farm Egg Production from Authentic Organic Agriculture.

The report contains an Organic Egg Scorecard that rates 70 name brand as well as additional private label organic egg producers based on 22 factors that the organization deems critical to the typical organic consumer. The main rating criteria include outdoor access, outdoor management, indoor quality of life and welfare, and organic principles of farm interdependence and ecological sustainability.

The highest rating, five eggs, goes to companies CI considers ethical family farms, companies that go beyond national organic standards. Most of these companies are small, local distributers.

The producers given the lowest rating, one egg, are those CI believes are in violation of organic standards of animal welfare and/or were not transparent with their practices during CI's research. Sadly, many of the single-egg brands are the ones most easily available to consumers. Whole Foods' 365 brand, Trader Joe's brand, O Organic by Safeway, and Costco’s Kirkland brand all received a single egg for their sup-par performance.

The report, conducted over a one year period, details how organic egg producers vary greatly in their interpretation of the Federal USDA Organic Standards, "Paths are diverging in the organic-egg-producing community: One path affords more outdoor access and more diversity on the farm; and another path has led to large-scale industrialization motivated by profit."

While Australia has quite strict rules about what is organic and its labelling, it is quite possible that similar issues occur here.

Normally a producer is "Certified Organic" which includes strict inspections and using verifiable organic inputs, and the "Certified Organic" term is used. Claims about "organic" products are often just "claims", unless they are certified as organic.

So be careful........organic eggs ain't always organic eggs!

Strategic Agricultural Land to be Protected from Gas Mining

Stunning new protection for strategic agricultural land has been announced for Queensland.

It is aimed very squarely at coal seam gas mining, and the potential for damaging land - land of high value for agriculture.

Believed to be a first in the world situation, the Queenslnd Minister for the Environment made the announcement today. Ironically, probably in the shadow of the Indonesian live export cattle slaughter saga, which has been major media news in Australia today, so media may not have picked up on the issue quickly. it is big news!

Anyhow.........read more here.
http://www.theaustralian.com.au/news/breaking-news/cropping-land-protected-from-mining/story-fn3dxity-1226066560517

There will be a lot more written over the next few weeks and months.

This is an amazing win for rural areas, in terms of land protection.

It is early days, but judging on views expressed at meetings I have been to on the Darling Downs, there will be a lot of very pleased rural landholders.

Comedy to Curb Littering and Waste

Littering is a serious problem in Australia and costs a lot of $$ to repair.

Conventional approaches have not always worked........so why not use comedy?

Keep Australia Beautiful has brought together an unlikely group of Australian celebrities to form a fictitious group called Litterers Anonymous. The comedic new anti-littering campaign aims to lift the profile of littering problems in Australia and will see Keep Australia Beautiful promoting the Litterers Anonymous ‘One Step Program’ which is simply to ‘use the bin’.

This campaign is supported by some of the leading companies in the beverage industry.

Keep Australia Beautiful will be launching the campaign in cinema, TV, radio and online this week at www.litterersanonymous.org.au

Litterer Types:

Wedgers - people who stuff disposable objects into small spaces where they will not be seen, such as behind a seat.

Undertakers – people who bury disposable objects under sand or leaves.

Foul shooters – people who aim for the bin but miss, and leave the object on the ground.

Using Carbon Dioxide for Algal Biofuels

It seems that Australia is about to move forward several steps in developing commercial use of waste carbon dioxide.

Origin Energy has announced a new medium scale [a prelude to larger scale use if successful] waste CO2 from its power plant to produce fresh water algae, which it then plans to harvest for potential biofuel production.

More here - http://news.cnet.com/8301-11128_3-20065708-54.html?tag=nl.e797

[ interestingly - reported in US not Australian media]

At about the same time, a leading US saltwater algal producer has announced a scaling up of existing work in the Pilbara region of WA, which uses CO2 from LNG processing as the accelerator of algal growth.

More here -http://au.news.yahoo.com/thewest/business/a/-/wa/9328127/algae-fuel-to-diversify-pilbara/

Both are in regions of Australia with plenty of sunshine, especially in the Pilbara.

Coincidentally, the aviation industry announced this week that they saw biofuel as a suitable fuel, with lowered CO2 emissions overall, as a substitute for existing fossil oil fuels.

Australia does have open spaces and sunshine, but so far a timid set of national and state governments, that seem reluctant to embrace non fossil fuels, although industry does seem more active to use them.

There is a major program in the private sector with wide support across industry and academia to develop base load solar thermal power stations, but so far without major support from government. More details are here -
http://beyondzeroemissions.org/blog/zero-carbon-australia-stationary-energy-plan-nsw-elements-110307

And there is a very comprehensive range of documents that do seem to provide evidence and analysis that would support the plan.

Could Australia prosper on waste carbon............after all, we are the highest per head producer of carbon???

Solar Panels with 90% Efficiency - Maybe!

It could be 5 -10 years away for commercial use, but with conversion efficiency of 90% it does sound impressive.

A new concept, so far restricted to lab scale, that could supplant traditional photovoltaics has been announced. The present photovoltaic systems commonly have efficiencies of around 20% and lower in warm climates.

Some fuel oxide fuel cells have around 85% efficiency of energy conversion, which is very high, but they rely on gas as a fuel source [ see www.cfcl.com.au - BluGen systems]. An efficiency of 90% would be stunning for a solar cell.

Read more below.
-------------------------------

AN associate professor in the University of Missouri (MU) Chemical Engineering Department is developing a flexible solar sheet with more than 90 percent efficiency.

If the technology comes good, it could revolutionise the solar energy industry, which is currently at around 20 percent efficiency with production-level photovoltaics. Scientists working in laboratories have thus far managed up to 25 percent efficiency.

According to Patrick Pinhero, the new technology does not utilise the traditional photovoltaic methods of solar collection, due to its inefficiency and failure to capture much of the available solar electromagnetic spectrum.

The device is a thin, mouldable sheet of small antennas called nantenna. These nantenna are currently used to harvest the heat from industrial processes in an energy harvesting application. Pinhero hopes to extend the concept to a direct solar-facing nantenna device which can collect solar irradiation in the near infrared and optical regions of the solar spectrum.

Working with his former team at the Idaho National Laboratory and Garrett Moddel, an electrical engineering professor at the University of Colorado, Pinhero and his team have now developed a way to extract electricity from the collected heat and sunlight using special high-speed electrical circuitry. The team also partnered with Dennis Slafer of MicroContinuum to port the laboratory bench-scale technologies into manufacturable devices that can be inexpensively mass-produced.

The team believes it will have inexpensive prototypes for consumers within five years. As part of a rollout plan, the team is securing funding from the U.S. Department of Energy and private investors.

The second phase features an energy-harvesting device for existing industrial infrastructure, including heat-process factories and solar farms.

Stormwater Management - Green Roofs Play a Part

The concept of using green roofs has more been around overall city heat mitigation, reduced heat absorption on concrete roofs, more oxygen in the city, even reuse of waste water.

Recent work has indicated that the 'green roof" may be significant in stormwater management, a slightly different outcome than was expected.

While Australia and many other regions do not have a single stormwater and sewer pipe system, some cities do. There the collection of stormwater on green roofs appears to greatly reduce the amount of stormwater entering the sewer system, and thus reduces the potential overflow, quite a problem for these types of systems.

In the areas with separate storm water and sewer disposal systems, it would seem that the collection of especially higher intensity storm rain, the event that often overloads streets and stormwater disposal designs, would also be enhanced, and less stormwater would flow through the system. And, even if it was partially reduced, it would most likely time shift and reduce the major flows, after the rain had flowed down through the green roof and then out down a drainpipe to the ground. The green roof would also assist with removal of pollutants, often in the rain in cities.

More details of the study here -http://www.enn.com/top_stories/article/42701

Green roofs lend themselves well to regions with some regular rainfall, year round. Has not been much development here in the NT, due to our very strongly seasonal rainfall - wet for half the year, generally totally dry for the other half, so plants require watering then.

There is a good example of a green roof in Singapore, at the Botanical Gardens. It seems to work well.

Camel Burger -To Go, Please

A lot of camels have been exported from central Australia, averaging around 3000 a year, yet camel populations continue to grow........exponentially........well almost so it seems.

There are a lot, and they mostly are considered as a feral animal issue. Their numbers are currently around one million. And continuing to rise, such that environmental degradation is a very serious issue as well as damage to towns and rural properties. A $19 million project to cull camels has been proposed.[ http://www.cbsnews.com/stories/2009/11/26/world/main5786556.shtml]

Quite a few have tried before to establish an overseas or even local market for the meat. It just has not been successful, and the slaughter process is often the problem. Camels require a specialised abbattoir, sized for them.



This time round, maybe there is more chance of success.

The proposal is to establish an abbatoir at Port Pirie, trucking the camels in for halal slaughter, then export chilled or frozen boxed meat. The proponent has established credentials in the middle east market for other meat products - sheep, goat and cattle so outlets are in place, plus there has been the development of some fast food camel burger outlets in Dubai, with another planned possibly for Abu Dhabi.

It might just be different enough to work.

read more here - http://online.wsj.com/article/SB10001424052748704628404576265783864754552.html

It would assist with reductions in camel numbers in Australia, provide jobs and income for remote areas and feed the Middle East. It might even be considered as organic camel meat. Maybe it has a chance.



UPDATE on 19 May

Food Prices WILL Go Up

Mankind has enjoyed several decades of falling food prices, and relative abundance. Some even say that food prices have really been trending down ever since about the mid 1800s, although there have been some periods where that has not been so clear.

Modern agriculture has improved productivity of most farm animals, crops and even trees and enhanced efficiency of the use of inputs such that more is produced for less.

Recent trends in agricultural productivity increases are much lower, a lot of the productive land is used already, some even disappearing into urban sprawl, and new areas are far less available, or have other constraints eg clearing of rainforest, and may even be less productive intrinisically.

Malthus and his predictions are back in the spotlight.

A recent short article from the Lowy Institue in Australia, a respected academic institue has examined this issue more critically.
link is here - http://lowyinstitute.org/Publication.asp?pid=1565 and the publication can be downloaded as a pdf.

We need 71% more food production to feed the world population of 9.1 billion [estimated] by 2050.

So far, it does not seem to be recognised as a serious issue, with R and D expenditure on agriculture still declining, and some are suggesting that it will be difficult to again obtain the agricultural productivity gains of the past 60 years. These are years in which use of hybrid crops, the development of the "green revolution" in Asia with both wheat and rice, etc etc all took place.

Genetic modification has been embraced by some.......and strongly rejected by others.

Many scientists do think that some form of major genetic advance will be needed to ensure this food will be produced, and that there will be significant changes in how and where food is produced. Will we see more food produced within cities? Many think so, grown in novel ways too.....even vertically on walls, replacing the lawn with a food garden, food grown on building rooftops and there will be greater use of recycled water and nutrients including organic materials eg compost. These are happening in some way already around the world.

At present there is a nett movement of nutrients from farms to cities, and it just about all goes down the sewer or into landfill. That might have to change.

Science might be capable to develop new food production systems but social and cultural adjustments might be needed too. They might be more difficult.

Plastic Bags - Worse Than You Think!

Many cities, towns and even countries [ China, Ireland, Australia] have banned already or are implementing plastic bag bans.

Sometimes there is opposition, sometimes very strong opposition, but in real terms their use drops enormously after steps are taken to restrict use.

Recent studies also are beginning to show that their impact is probably more damaging than previously thought.

The article link will bring you up to date on more recent studies..........and it is generally NOT GOOD.

http://e360.yale.edu/feature/facing_the_dirty_truth_about_recycled_plastics/2400/

Plastics are a serious issue in relation to disposal and / or recycling, and much more needs to be done in that area.

At least in Darwin they have finally allowed more classes of plastic to be recycled. A good start, I suppose.

Compost Awareness Week - May - 2011

It is International Compost Awareness Week this week...........with functions around the globe. The USA, Canada, UK and Australia are examples.

The message below is focussed on the East Coast of Australia, but relevant all over Australia.

Composting, the ‘intelligent’ alternative
Tuesday, 3 May 2011

That’s the message from the Centre for Organic & Resource Enterprises (CORE) at the launch of the sixth International Composting Awareness Week (ICAW). Organised in conjunction with Compost Australia (a division of the Waste Management Association of Australia), the week of events from May 1-7 will promote the benefits afforded to us all when our business communities and households get involved in composting.

“Composting is the responsible and sustainable thing to do for our planet,” according to CORE.

The major objectives of ICAW are to increase the diversion of organics from the main waste collection program through increasing awareness and participation in centralised composting, kerbside collections, home composting and community composting.“Each year over half the household garbage we produce is made up of food and garden organics. Most of this organic waste can be recycled by composting it”, said Eric Love, chairman of CORE.“If all this organic material was diverted from landfills and properly composted, it could be used to reverse the affects of climate change.

By applying this compost to gardens, farms and other land uses, millions of tonnes of carbon will be stored in the soil. This acts to lower the atmospheric temperatures that lead to changes in our climate.”

ICAW also aims to increase awareness and knowledge about the correct use of "soil-improving composts"; help reduce and recover food waste; and highlight the environmental and social benefits of composting including the opportunities to reduce our carbon emissions.

“Composting is not new. Compost has been used in crop production for over 4,000 years. Artificial fertilisers only became widely available a century ago. Australia is an old and eroded continent that is suffering from land degradation,” said Love.

Emissions from landfills are part of the Australian Federal Government’s carbon abatement initiative. If everyone composted, the total waste going to landfill could decrease by up to one third and emissions and disposal costs will drop, according to CORE.

Peter Wadewitz, chairman of Compost Australia said, “Compost produced by the recycled organics industry is already providing Australian landscape, horticulture and agricultural industries with affordable solutions to improve productivity and environmental outcomes.“Recycled carbon based products are also being effectively used to treat contaminated stormwater runoff and enabling the water to be reused, or more safely released into our waterways.”

Kimbriki Resource Recovery Centre is getting into the action of ICAW by offering talks, demonstrations and tours at its Ingleside/Terrey Hills site on May 3, 4 & 5 (at 10am and 2pm).

It will also give away 500 bags of Kimbriki Compost each day. Peter Rutherford, Kimbriki’s senior ecologist, will demonstrate simple ways to make great compost at home, and explain how this relates to healthy plants and healthy people. Australian Native Landscapes’ soil expert, Rob Niccol, will discuss composting and soil health; explain about the value of compost in larger projects and how it is being used to supplement Australia’s dwindling soil resources. He will also demonstrate the latest in mulch blowing technology and conduct a guided tour of the large-scale compost making operation at Kimbriki.

Less Water Use Reduces Energy Too

Water use and water loss is a major energy cost in many countries.

If just 1% of US homes replaced older, inefficient toilets with dual flush models, the country would save more than 38 million kWh of electricity, the equivalent of 43,000 households’ monthly electrical supply.

While in Australia, dual flush and reduced flush toilets are very common, they are much less common in other countries. As an example, 25 years ago most Australian toilets were single flush, 12L per flush. Best models today are 6L/3L flush with a redesigned efficiently flushed pan, or the more common 9L/4.5L dual flush models. Practically, volumes less than these levels can create congestion problems in sewer lines as the liquids level has diminished so much..........but most countries are nowhere close to the reduced flush volumes now common in Australia.

Big water use reductions are possible, and an important issue, rarely considered is that less water used means much less energy is used. Think electricity for pumping and purifying water as the most obvious point.

Solving leakage is also important in reducing energy use, as a side benefit of reducing water losses. Same issues as above.

Switching to dual flush low volume toilets is a big factor in driving reducing energy use.

Sandalwood Offers a Pathway to Reduced Animal Methane Emissions

Welsh University discovers way to reduce methane from cows and sheep

Research carried out by academics from Aberystwyth University has resulted in a discovery which could lead both to an improvement in milk and meat production and to a significant reduction in methane emissions from cattle and sheep.

The research team, led by Professor Jamie Newbold of Aberystwyth University, found that by adding sandalwood (or a sandalwood analogue) to animal feed the growth of pathogenic bacteria such as E.coli and Listeria in the rumen is reduced. As a consequence, energy which would otherwise be lost through the production of methane is diverted to increased milk and meat production.

At the same time there was a significant reduction in the emission of methane, a greenhouse gas with 23 times the global warming potential of the equivalent amount of carbon dioxide. It is estimated that livestock produce 18% of all global greenhouse gas emissions, more than all forms of transport combined.

Trials in a rumen simulating fermenter (Rusitec) confirmed that Javanol, a sandalwood analogue, reduced methane production by up to 25%. A reduction of 20% in methane emissions was achieved in field trials with sheep when 2ml of Javanol per day was added to their diet.

This is an exciting discovery in two ways," said Dr Ahmed Ali. "Firstly, there would be benefits to the agricultural industry through increased milk and meat production: this increase in productivity would be set against a background of growing pressures on global food supply.
Secondly, there could be a significant reduction in methane emissions."

"Overall, the project is a good example of a University and an SME collaborating on cutting edge research. If this project and projects like this, can be commercialised in global markets, that has to be the way forward for the knowledge economy of Wales."

This might be a plus for Wales, but what about use in Australia, especially those areas of Australia where sandalwood is grown - the NW of Western Australia, SW of WA as well as parts of the Northern Territory. Sandalwood and oil products from the tree are high value materials, strong in demand from perfumery manufacturers.

It is especially important for monsoonal tropical regions, as it is known that methane emissions in livestock increases when animals are on feeds with lower digestibility, a common issue in the dry season when dry feed is most commonly consumed.

Could a small addition of sandalwood or similar materials to metered and medicated water dispensing systems which are increasingly common, offer some options for reducing methane emissions of livestock in north Australia??

Small Business = Technological Cretins

A recent report has absolutely slammed the uptake of new technology by Australian businesses.

Low use of mobile phones and computers are targetted in the report based on some research by Telstra, Australia's largest phone company.

The figures are quite stunning, [ full news report here - http://www.theaustralian.com.au/business/news/small-business-lagging-behind-in-technology-study/story-e6frg90f-1226047835735 ]

Data for a sample of small businesses are that nearly one-quarter did not use a standard mobile phone, while 45 per cent did not have smart phones. One in ten did not have a computer associated with the business. Around half of the businesses surveyed did not have a website or use online transactions in their business.

I can understand the lack of a website - they can be a bit daunting and expensive at times for a decent website, but no online transactions is bit odd. How do they do their banking transactions or employee payments??

While I have no data for the Northern Territory, national figures do seem a bit odd based on what I see in local NT small business, or maybe it reflects the younger population here.

However..........Telstra thinks they may be on a winner in being able to provide services.

Most people just wish they would improve their telephone performance around the country.

Long Chain Omega-3 Oil from Plants - Soon

A pioneering Australian research alliance is leading the international race to break the world’s reliance on fish stocks for its supply of the vital dietary nutrient, long chain omega-3.

Three Australian organisations recently announced an A$50 million dollar research collaboration which will use leading edge gene technology to develop and commercialise vegetable oil which will contain the same high quality, DHA (docosahexaenoic acid) rich long chain omega-3 that traditionally comes from fish.

This collaboration brings together Nuseed (a wholly owned subsidiary of Nufarm Ltd), CSIRO and the Australian Grains Research and Development Corporation (GRDC).

Already as part of the project, CSIRO scientists have made a significant breakthrough by enabling canola plants to generate long chain omega-3 oils that contain DHA, something that up until now has only been found in beneficial quantities in ocean-based algae and the fish that eat it. Some land-based plants, like flaxseed, can produce short-chain omega-3 oils, but are unable to produce the more beneficial long chain omega-3 oils containing DHA.

CHOCOLATE TAX??

Here in Australia, chocolate eggs are very common gifts at Easter, with the egg representing life, as shown by the Christian festivity of the Resurrection, on what is celebrated as Easter sunday.

There has been a call by Tim Costello, the head of World Vision Australia for a tax on chocolate.



No, it is not a crazy thing, but all about the fact that much of the world's chocolate production comes from west Africa, where child slavery and related systems of indentured or sold adult slaves, do much of the work in cocoa production. it is estimated that about 97% of cocoa produced around the world involves child exploitation.


There have been some efforts to overcome the system with Greens chocolate [ based in the UK]attempting to break out of this production cycle, by introducing fair trade type policies around cocoa sales and purchases [ recently written about in Time Magazine], as have Cadbury's.








But the call from Tim Costello is new, and World Vision does have some clout in these issues. Read and hear more here -http://www.abc.net.au/rn/breakfast/stories/2011/3196200.htm .


It is not a nice issue to contemplate in a comfortable westernised society, but cocoa production does remain as one of the last areas of serious child slavery in the world.


Be aware of that fact as you eat your chocolate Easter eggs............or just about any other chocolate!!

NEW RECORD - World's Hottest Chilli Grown in Australia

A record worth claiming for some, and totally irrelevant for many others.

Have to have some levity ocassionally.


A chilli grower on the Central Coast of NSW, in Australia has produced what is believed to be the world's hottest chilli, the Trinidad Scorpion Butch T.


"It was like a eating a fruit salad and then it just exploded in my mouth, it was fantastic!" described Marcel de Wit, head grower at the Chilli Factory, the producer who grew the chilli.


This is supposed to be a new record, surpassing the chillies produced in Assam.[

Sustainability - Great Disruption

In sustainability terms, as well as ecological, a population can grow, reach the limits then decline. For various reasons. Jared Diamond wrote of this theme in his books in the 1990s, as did Paul Erlich to some degree in "Limits to Growth" [1970s].

A recent book by Paul Gilding, "The Great Disruption" adds to the debate about sustainability. The book was reviewed here [ http://www.environmentalmanagementnews.net/storyview.asp?storyid=2336764&sectionsource=s0 ] during the week, and is now available for sale in Australia. No doubt Amazon will have it also.

The reviewer reckons it is a good read. But maybe they are too similar in views for a dispassionate review. Maybe there cannot be a dispassionate review of the topic.

Read it and comment.

It should stir considerable controvesy.

Mangroves - Worth Loving for Carbon Storage

Mangroves have been under threat as mankind increasingly lives near the water's edge - especially the saltwater edge!

Maybe recent events such as earthquakes and tsumanis might encourage a rethink living on the edge of the sea, but for now, many areas of mangroves are torn out for development - of various kinds.


One school of thought even suggests that their prsence along coastlines mitigates cyclonic storm surges and related events, preventing considerable damage, even some distance inland. I recall comments about several major storms in Asia where more damage occurred than might be expected due to the removal of protection from mangroves, torn out for aquaculture development.


Land developers commonly remove mangroves to develop canal estates too.


Some recent scientific research on tropical mangrove trees show they are better at storing carbon dioxide than most other forests, and cutting them down unleashes more greenhouse gas than deforestation elsewhere.
Mangroves are so efficient at keeping carbon dioxide out of the atmosphere that when they are destroyed, they release as much as 10 per cent of all emissions worldwide attributable to deforestation - even though mangroves account for just 0.7 per cent of the tropical forest area, according to some new research.

Daniel Donato, of the
US Agriculture Department's Forest Service and lead author of a study published in the journal Nature Geoscience, says mangroves store two to four times the carbon that tropical rainforests do. "Mangroves store a lot of carbon, much more so than most forests on Earth, on a per hectare basis," says Donato. "Since they store so much carbon, there's probably a lot being released from all the mangrove deforestation that's going on."

Yes, if you live near the coast you tend to dislike the mangroves - the source of mosquitoes and sand flies, midges and related biting insects.


Maybe it is better you protect yourself, and leave the mangroves to store carbon and protect us from natural disasters.

Snail Biosecurity - Even in Singapore

A visitor to Singapore sees a lot of hard surfaces and little of the green sites.

Seemingly the island appears as a large building, apartment and mall site.


However, surprisingly, the island does have a few biosecurity issues of concern.


A recent article expresses considerable concern over a snail found in some Singapore green sites, such as plant nurseries and remnant jungle areas.


http://news.mongabay.com/2011/0328-hance_tcs_snail_singapore.html

African land snails are a particular issue of concern to many biosecurity agencies around the world, including Australia. The species in this article is not the normally noted one, but still a potential species of some concern. There are comparison photos in the article.


It is true that plant quarantine is often not an issue of major concern to Singapore, especially for outsiders, but it is for Australia.


The Singapore story seems to implicate plant imports as the source of the snail.


While plant imports to Australia from Singapore are not that common, orchid flowers can be a fairly common passenger item, and there is a history of insects as a free rider on the flowers.


Darwin - watchout for this snail.

Cheap Distributed Energy for Rural Development

In India, Tata, one of the industrial giants of the country is working through concepts to invest in cheap distributed power supply in rural areas.

The company believes there is a market.......if not today, then soon. And they are positioning themselves to be part of it.


Sure, one thinks of solar powered telephone towers, remembering that the entire microwave repeater system across the north of Australia was run on solar power, and that was 25 years ago. So that is not new.


There are other options too, including local use of biomass produced for fuel such as palm oil, or other crop oils used in small diesel motors to run local cottage industry or produce modest amounts of electricity.


Tata is doing this big time though.


Does their model also offer some hope for many other rural and remote regions across Asia and Africa especially?

Compadre Zoysia - Choice For High Profile Area in Central Palmerston, NT

As part of the beautification of the central area of Palmerston, the Palmerston City Council has used Compadre zoysia, sown from seed, as a key component of the landscape plan. Seed sowing offered a much lower cost than using turf sod, although slower, yet allowed satisfactory development over about 16 - 20 weeks of an area that will be used for many years. The area links the public bus terminal and many of the current office buildings at the northern part of the central business area, including the Council offices, Goyder building and Post Office.

Both sides of the pedestrian pathway are sown, with trees along the road verge.


The site was prepared and sown in mid 2010, on a reasonably shallow laterite site that had modest topsoil applied.


Although germination and establishment were slower than expected, the cooler conditions of the mid dry season impacted on this with growth quickly improving from September. Slow establishment is common in the Dry season, with almost any turf grass.


The site suffered due to prior rural use of the area, and numerous plants of the pasture species of stylo also established.
Several rounds of herbicide sprays to control these weeds, along with sedges that appeared in the very wet conditions of the 2010/ 2011 wet season, were needed to develop a satisfactory turf surface.

Importantly for the Council, it does seem that reduced mowing frequency [about half of normal frequency] is practically possible with Compadre zoysia, achieving a great appearance at reduced mowing cost.

Mowing costs are a major component of long term turf maintenance on commercial areas, and less frequent mowing can reduce overall costs of the area.
The aesthetics are superb.........even if it was raining when the photos were taken in mid March 2011!

There have been some initial additional costs with weed control, but they are not huge and mowing less often will recover these costs very quickly.


The area has been established only about 8-9 months, and with the shorter dense turf cover, it does look impressive.

Zoysia Compadre Turf at Darwin Waterfront - Early 2011 Update

The Darwin Waterfront Project used Compadre zoysia as the turf grass of choice, and it was sown from seed in late 2009. Conditions after sowing were not ideal, in fact definitely difficult, with very heavy tropical strom rain and problems with soil movement that required significant intervention by the contractor. Despite the problems, the area was sown and the Compardre zoysia grew satisfactorily after some repair work following the storm damage. Now, about 16 months later the area is fantastic.
The sown turf has very few weeds, is lush and green, and well used. Mowing frequency has been reduced to a lower level, turf density is very high and the grass provides great lateral density such that it is impossible to see any ground.

A great turf area has been achieved primarily through mowing and allowing the Compadre zoysia to develop its thick carpet of turf.



Especially important, has been the excellent growth in shady areas where ground cover is really no different to open sunny locations. Compadre zoysia is recognised as an excellent shade tolerant grass. It is soft, non itchy and usually well patronised by those using the swimming lagoon and wave pool.

Right now, that is not too many...........the rain has been keeping patrons away, especially tourists who are usually very regular users of the area!


The photos are from early March 2011, after about 3 months of very heavy wet season rain this wet season. There has been no problem with erosion and the grass is ...........well, great

This is a high profile site and Compadre zoysia has shown it can be a very acceptable and desirable turf lawn in the region.

Wind Energy in China

The wind energy potential in China is very substantial.

The ordinary citizens of most western countries are generally ignorant of the advances that are happening in alternative energy developments in China, with many media stories focussed on energy from coal, and quite dirty energy too. Wind energy particularly has developed enormously over the past 15 years or so. In the mid 1990s, there were the emergence of some significant wind energy projects often funded by the EU or member countries.

Developments since then have been, well, like many things in China - absolutely enormous.

Currently, China's wind power installed capacity has reached 42GW at the end of 2010, and is the largest wind power producer in the world. By contrast Australia's wind energy capacity is about 2GW [2009 data], yet we have significant resources, not being used.

China is expected to increase capacity to 135 GW in 5 years and 513 GW in 20 years, according to some sources. This means in the next 20 years, China will add an average of about 25 GW of wind power installed capacity and invest more than 25 billion Euros in the wind power market every year.

The land-based wind energy resource in the western region of Xinjiang accounts for 37% of the national total. By the end of 2015, Xinjiang's wind power installed capacity will reach 60 GW.

To further enhance these develpment projects a major conference in May is being held in Urumqi [Xinchiang Province] to attempt to bring projects and money together.

China does need clean energy, as much energy currently is from some pretty dirty coal power plants. But.......watch China........I think we shall see a very large incease in alternative energy as a power source, with wind a large part of that increase.

They are planning a lot of nuclear power plants too.............although no doubt like others, the recent Japan incidents might influence their thinking.

Less Greenhouse Gas - Modest Steps and Tangible Actions Work

A lot of the debate around alternate energy, energy efficiency and even a carbon price or tax has focussed on climate change. That nebulous, end of century effect that no one is really sure about whether real or imagined, and which sceptics of climate change then have great delight in demolishing any argument to do anything about issues now. I am not a sceptic of man driven climate change, but for many it is just a difficult concept.

The ex Governator - or maybe the ex Terminator - has had quite a bit to say over the past few days, while delivering a very well received address at a conference in the US. And it offers some common sense about effecting change.

His premise is that climate change is just too abstract for most people to conceive [ apparently especially Americans] and that those wishing to effect change at grass roots level and in society need to be focussing more on real effects now, tangible things. These include:

  • job creation from green jobs related to mandated renewable energy use,
  • reductions in oil use and hence dependence on other countries for energy,
  • energy efficiency that offers real benefits in reduced costs due to efficency improvements in homes and businesses,
  • health benefits from reduced use of oil,
  • vehicle efficiency improvements to reduce fuel use,

among a range of issues.

http://news.cnet.com/8301-11128_3-20037752-54.html?tag=nl.e703

offers a reporters view of the address.

This seems a very pragmatic approach, well wrapped in some humour too, and does offer a way forward at even local levels. Getting back to the old cliche - "act locally, think globally' a catch cry slogan of the environment movement. And implies a degree of personal responsibility, in California's case also in some areas offering state support.

There have been a number of reports available of business case studies that created quite substantial real $$ savings by embracing energy efficiency, for example and many jurisdictions do have programs to assist in taking this approach and actions.

Clean Technology in Mexico - A Lesson for Australia?

To many Australians, Mexico is not on the business horizon. It might be a fun location to visit......but not for business.

That is a little different in livestock production where there has been a reasonably strong connection between the tropical livestock and pastoral industries for some time. Can Mexico offer some ideas for clean technology devlopment that might be relevant in Australia? They do have a large adjacent market in the US, although some would argue that Australia does have a similar market......the countries of Asia.

Mexico may have a few ideas to also show Australia in relation to development of major initiatives in clean energy including geothermal sources, at least in shallow source areas. Some might counter this and say, so does New Zealand in geothermal sources, with both using hot rocks and steam associated with vulcanism, not a situation seen readily in Australia though.

Mexico has also been ramping up PV use.

http://blog.cleantechies.com/2011/02/28/highlights-cleantech-mexico/

is a recent rticle highlighting developments in clean tech in Mexico.

Could some of this be relevant for Australia?

Carbon Pricing in Australia

July 2012 will see a carbon price implemented in Australia.

Is it a carbon tax? Well, yes I guess it is. But views as to using carbon tax versus an ETS have evolved and changed over the past several years, with the complexity and bureaucratic shemozzle of an ETS seen as a big stumbling block to any implementation of a scheme about climate change. A carbon tax is seen as economically efficient.

Neither is perfect.

A lot more detail still to come, and a few heads will no doubt get kicked along the way.
It is probably fair to say only the absolute diehard sceptics still subscribe to a view that climate change is not real and happening.....and maybe accelerating, even if there is some noise about normal cyclic movements in climate, sometimes attributed to changes in the solar energy cycles.

An interesting piece has been seen on the ABC web site today:[http://www.abc.net.au/news/stories/2011/02/25/3148883.htm ]

This is a reasonable cover of the issues, without getting into the trade exposed intensive industries arguments that were discussed during the previous ETS discussions.

But this option of a tax can be done now and should send appropriate signals to consumers and industry that there is not a free ride anymore.

It should be an interesting period over the next few years as this evolves......or gets stymied depending on how the political pieces fall.

How to Effect Climate Change - NOW

While we all wring our hands and think that government and our institutions are doing little about climate change - too hard, too many parties to get to work together and so on, there may be some options that can provide effect in both the near term as well as mid term.

And they use existing technology.........and can be implemented now.

Methane is a clear problem gas in the atmosphere, with much greater greenhouse gas potential than carbon dioxide. While methane from ruminants is often seen as giant problem, it is also a problem from termites. And either issue might not be fixed any time soon, although higher quality feed for ruminants does help in their case to reduce methane emissions.

The following link to a recent report published / presented on 23 February does seem to offer some sensible suggestions.

http://www.scientificamerican.com/article.cfm?id=cutting-black-carbon-methane-immediate-climate-change&WT.mc_id=SA_CAT_TECH_20110222

The issue of methane from landfill is a significant one and in Australia, many of the larger municipal sites do collect and utilise methane, with data available during the now aborted ETS scheme showing about an average of around 65% of produced methane being collected.

Australia is in the small league as regards landfills however, with much more potential in north America.

There is also a developing industry of anaerobic digestion of organic materials to generate methane, prior to aerobic composting. A sensible development, in both rural areas [ dairy herds, feedlots for example] as well as larger urban areas generating food wastes.

We need to start now though, if we are to have a reasonable chance of restricting temperature rise to the two degrees desirable.

Agriculture and Innovation

Agriculture and horticulture often get some bad publicity as being stuck in using ancient ideas and that people in these industries are old fuddy duddies without much innovation.

I would say that is probably the exact opposite of real world situations. Innovation is alive and very well in these two industries, and seems to have been around for well over a hundred years. While it is often true that farmers are older on average than the population, they still embrace new ideas.

Whether it has been mechanisation and machinery development, application of technology in plant breeding or use of new products including herbicides and pesticides, satellite navigation and related use in yield mapping of paddocks, driverless machinery, use of RFID systems for animal identification and management..............the list can go on, and on!!

This recent snippet reinforces the view that agriculture is VERY progressive, and has been for a very long time. I am sure that even today, the same story can be repeated about Australia, Canada, Brazil, and Argentine, as well as the USA.



February 1911 - Scientific American Magazine

Inventors and Farmers

“In all the history of empire building there is no chapter to compare with that which tells the story of the development of the great West from a vast stretch of prairie, desert and primeval forest into the richest and most extensive agricultural empire in the world.

The rapidity and completeness with which this transformation has been effected are chiefly due to the invention of agricultural machinery of wonderful precision and capacity. The mechanical engin­eer has at once simplified work and increased output from the farm.”


It is still taking place across all the major agricultural producing countries today.............2011!

Origin of Insecticides

In browsing Scientific American magazine of February 2011, the following brief note appeared in the highlights of 150 years ago - February 1861.

Modern agriculture and horticulture does have a degree of reliance on both herbicides and insecticides, although some would say that is changing as biotechnology makes advances and GM crops advance.

Whether true or not, pyrethrin was one of the very earliest insecticides. And the snippet below provides some interesting thoughts from 150 years ago.

February 1861 - Scientific American Magazine

Pyrethrin Insecticides


“A vegetable powder, under the name of ‘Persian Insect Powder,’ has lately been introduced into the drug market, for the extermination of insects, vegetable parasites, &c.

Until recently, the botanical source of this powder has not been known, except to its maker. For a number of years it was erroneously considered to be a native of Persia, but it has been traced beyond question by Dr. Koch, as having its origin in the Caucasian provinces, and to the contused blossoms and flowers of Pyrethrum roseum and Pyrethrum carneum.

It is of a yellowish, gray color, perfectly odor­less, yet slightly irritating to the nostrils; at first almost tasteless, but afterwards leaving a burning sensation upon the tongue.

As its effects for the destruction of bugs, roaches, parasites on delicate plants, &c. have been fully established, and it being otherwise harmless, its introduction into general use would be of great importance to families and horticulturists.”
