Pope Francis Pushes for Environment and Climate Change Sensibility - Encyclical 2015

Yes, the Pope has spoken out on the environment.  A link will take you the document in English but it is also available in a number of other world languages including Arabic too.

 http://w2.vatican.va/content/francesco/en/encyclicals/documents/papa-francesco_20150524_enciclica-laudato-si.html


Available publicly the day after the Australian document on developing north Australia is ironic. That document continues to foster debate in Australia today, with extensive media coverage and more expected in coming weeks and months.

The Pope does not pull any punches in his encyclical and quite clearly in layman's terms comes out to support the premise that a major cause of climate change has been and is now, atmosphere changes from increased levels of greenhouse gases from burning fossil fuels also leading to other effects.

He uses clear, easy to read language and does document material, relying on scientific evidence.

There are a few excerpts around with this one which appeared on the ABC web site in Australia a reasonable overview  - http://www.abc.net.au/news/2015-06-19/pope-francis-warns-humanity-about-pace-of-consumption/6557822

" Pope Francis has issued a major encyclical on the environment, called Laudato Si (Praise Be), On the Care of Our Common Home. Here are some key excerpts from the official English version:
On climate change and its causes
In recent decades this warming has been accompanied by a constant rise in the sea level and, it would appear, by an increase of extreme weather events, even if a scientifically determinable cause cannot be assigned to each particular phenomenon. Humanity is called to recognise the need for changes of lifestyle, production and consumption, in order to combat this warming or at least the human causes which produce or aggravate it. It is true that there are other factors (such as volcanic activity, variations in the Earth's orbit and axis, the solar cycle), yet a number of scientific studies indicate that most global warming in recent decades is due to the great concentration of greenhouse gases (carbon dioxide, methane, nitrogen oxides and others) released mainly as a result of human activity. Concentrated in the atmosphere, these gases do not allow the warmth of the sun's rays reflected by the Earth to be dispersed in space. The problem is aggravated by a model of development based on the intensive use of fossil fuels, which is at the heart of the worldwide energy system.

On dangers to the planet
If present trends continue, this century may well witness extraordinary climate change and an unprecedented destruction of ecosystems, with serious consequences for all of us. A rise in the sea level, for example, can create extremely serious situations, if we consider that a quarter of the world's population lives on the coast or nearby, and that the majority of our megacities are situated in coastal areas. Climate change is a global problem with grave implications: environmental, social, economic, political and for the distribution of goods. It represents one of the principal challenges facing humanity in our day. Its worst impact will probably be felt by developing countries in coming decades.
Doomsday predictions can no longer be met with irony or disdain. We may well be leaving to coming generations debris, desolation and filth. The pace of consumption, waste and environmental change has so stretched the planet's capacity that our contemporary lifestyle, unsustainable as it is, can only precipitate catastrophes, such as those which even now periodically occur in different areas of the world. The effects of the present imbalance can only be reduced by our decisive action, here and now. We need to reflect on our accountability before those who will have to endure the dire consequences.
On consumption, sustainable development and wealth disparity
We all know that it is not possible to sustain the present level of consumption in developed countries and wealthier sectors of society where the habit of wasting and discarding has reached unprecedented levels. The exploitation of the planet has already exceeded acceptable limits and we still have not solved the problem of poverty.
We fail to see that some are mired in desperate and degrading poverty, with no way out, while others have not the faintest idea of what to do with their possessions, vainly showing off their supposed superiority and leaving behind them so much waste, which, if it were the case everywhere, would destroy the planet. In practice, we continue to tolerate that some consider themselves more human than others, as if they had been born with greater rights.

On fossil fuels
There is an urgent need to develop policies so that, in the next few years, the emission of carbon dioxide and other highly polluting gases can be drastically reduced - for example, substituting for fossil fuels and developing sources of renewable energy. Worldwide there is minimal access to clean and renewable energy. There is still a need to develop adequate storage technologies.
We know that technology based on the use of highly-polluting fossil fuels - especially coal, but also oil and, to a lesser degree, gas - needs to be progressively replaced without delay. Until greater progress is made in developing widely accessible sources of renewable energy, it is legitimate to choose the lesser of two evils or to find short-term solutions. But the international community has still not reached adequate agreements about the responsibility for paying the costs of this energy transition.
On political myopia and bureaucratic inertia
Recent world summits on the environment have not lived up to expectations because, due to lack of political will, they were unable to reach truly meaningful and effective global agreements on the environment.
A politics concerned with immediate results, supported by consumerist sectors of the population, is driven to produce short-term growth. In response to electoral interests, governments are reluctant to upset the public with measures, which could affect the level of consumption or create risks for foreign investment. The myopia of power politics delays the inclusion of a far-sighted environmental agenda within the overall agenda of governments.
On market forces and carbon credits
Once more, we need to reject a magical conception of the market, which would suggest that problems can be solved simply by an increase in the profits of companies or individuals. Is it realistic to hope that those who are obsessed with maximising profits will stop to reflect on the environmental damage which they will leave behind for future generations? Where profits alone count, there can be no thinking about the rhythms of nature, its phases of decay and regeneration, or the complexity of ecosystems which may be gravely upset by human intervention.
The strategy of buying and selling "carbon credits" can lead to a new form of speculation, which would not help reduce the emission of polluting gases worldwide. This system seems to provide a quick and easy solution under the guise of a certain commitment to the environment, but in no way does it allow for the radical change which present circumstances require. Rather, it may simply become a ploy which permits maintaining the excessive consumption of some countries and sectors.

On relationship between banks, environment and production
Saving banks at any cost, making the public pay the price, foregoing a firm commitment to reviewing and reforming the entire system, only reaffirms the absolute power of a financial system. A power which has no future and will only give rise to new crises after a slow, costly and only apparent recovery. The financial crisis of 2007-08 provided an opportunity to develop a new economy, more attentive to ethical principles, and new ways of regulating speculative financial practices and virtual wealth. But the response to the crisis did not include rethinking the outdated criteria which continue to rule the world.
Production is not always rational, and is usually tied to economic variables which assign to products a value that does not necessarily correspond to their real worth. This frequently leads to an overproduction of some commodities, with unnecessary impact on the environment and with negative results on regional economies.
The financial bubble also tends to be a productive bubble. The problem of the real economy is not confronted with vigour, yet it is the real economy which makes diversification and improvement in production possible, helps companies to function well, and enables small and medium businesses to develop and create employment.

On effect of mining on the environment and local people
Underground water sources in many places are threatened by the pollution produced in certain mining, farming and industrial activities, especially in countries lacking adequate regulation or controls. It is not only a question of industrial waste. Detergents and chemical products, commonly used in many places of the world, continue to pour into our rivers, lakes and seas.
The export of raw materials to satisfy markets in the industrialised north has caused harm locally, as for example in mercury pollution in gold mining or sulphur dioxide pollution in copper mining. There is a pressing need to calculate the use of environmental space throughout the world for depositing gas residues which have been accumulating for two centuries and have created a situation which currently affects all the countries of the world.
In this sense, it is essential to show special care for indigenous communities and their cultural traditions. They are not merely one minority among others, but should be the principal dialogue partners, especially when large projects affecting their land are proposed. For them, land is not a commodity but rather a gift from God and from their ancestors who rest there - a sacred space with which they need to interact if they are to maintain their identity and values. When they remain on their land, they themselves care for it best. Nevertheless, in various parts of the world, pressure is being put on them to abandon their homelands to make room for agricultural or mining projects which are undertaken without regard for the degradation of nature and culture.

On public pressure on companies and boycotts

A change in lifestyle could bring healthy pressure to bear on those who wield political, economic and social power. This is what consumer movements accomplish by boycotting certain products. They prove successful in changing the way businesses operate, forcing them to consider their environmental footprint and their patterns of production. When social pressure affects their earnings, businesses clearly have to find ways to produce differently. This shows us the great need for a sense of social responsibility on the part of consumers.  "
------

The full document is about 82 pages and if interested in the environment is essential reading, covering ethical issues about the environment and how it has influenced social and moral issues.

I am sure it will not be forgotten as ordinary citizens, scientists and politicians pore over the document in the coming weeks and months.

The Pope carries a bit of clout, and the document and various extracts will be widely read .......worldwide.

Will it influence the world's politicians?  Early days, but the US President has reacted positively to the material.

Lets hope that a decent outcome can be achieved later in 2015 at the climate summit in Paris.  The Pope seems to believe that significant change is needed..........for the world and us.

Waste Tyres - Not Necessarily Anymore

We have been associated with some technology to use end of life tyres in civil construction.  It works very well and is described at www.ecoflex.com.au .

But more is happening in this space with a lot of success using tyres in steel making.

UNSW collaborated with industry partner OneSteel to develop ‘green steel’ technology, wherein old tyres and plastics provide a source of carbon to replace a significant proportion of the non-renewable coke used to make steel in electric arc furnaces.
The ‘green steel’ technology invented at UNSW has now achieved a major milestone, with its use in Australia preventing more than two million waste rubber tyres from ending up in landfill. The discarded tyres were used by OneSteel, an Arrium company to manufacture steel at its Sydney and Melbourne facilities.
UNSW Scientia Professor Veena Sahajwalla collaborated closely with OneSteel to develop the polymer injection technology.
Professor Sahajwalla, Director of the Centre for Sustainable Materials Research and Technology (SMaRT@UNSW) in the Faculty of Science said they were thrilled to have surpassed the two-million tyre milestone. The achievement demonstrates the benefits of collaborations between researchers and industry.
Under an agreement with UNSW’s commercialisation company, NewSouth Innovations, OneSteel has sub-licensed the technology to companies in Thailand, South Korea and the United Kingdom and has plans to further commercialise it around the globe.
Daniel Miles, Manager Steelmaking Solutions at OneSteel observes that close collaboration between OneSteel and UNSW has turned an innovative idea into a manufacturing reality. He explains that polymer injection technology is not only good for the environment, but also offers financial benefits for the steel manufacturer in terms of reduced electricity consumption, lower carbon injectant costs as well as yield and productivity improvements.
Professor Sahajwalla is now working towards her goal of a 100 per cent recyclable car, developing high-temperature technology that can turn waste glass and plastic into valuable metallic alloys – an approach that could also be used to transform electronic waste.
Professor Sahajwalla was awarded $2.2 million earlier this year by the Federal Government to establish a ‘green manufacturing’ research hub at UNSW, with industry partners including Arrium, Brickworks Building Products, Jaylon Industries and Tersum Energy.
In August, Professor Sahajwalla was awarded a prestigious Australian Laureate Fellowship worth $2.37 million.


This work is absolutely awesome and demonstrates how innovative thinking can solve BIG problems!

Will EU Overfishing Finally Be Curtailed?

Australia has been called the lucky country often and for many and varied reasons.  On the world fishing scene we are a minnow, maybe a baby sardine - whatever, pretty small!

But strong efforts over recent years have reduced our fishing effort to encourage additional fish stocks in the region, and in the north ther eis a strong effort to protct Australia's sovereign fishing territory from outsiders and even local overfishing.

Europe has for many years been radically reducing their fishing stocks, even to the point where some fisheries have disappeared.  Fishing effort has increased, but still smaller numbers and smaller fish are being caught.

Getting agreement has been impossible among the EU nations not to mention the fact that some major fishing nations are operating but are outside the EU.

It seems that change is possible, and while tough there seems to be finally a realisationtha tunless radical steps are taken there will not be any fishery remaining - of almost any type- in a relatively few years.

A recent report here -

http://e360.yale.edu/feature/will_reform_finally_end_the_plunder_of_europes_fisheries/2623/

seems to finally offer some hope that the reforms needed to reduce fishing effort, eliminate or better manage by-catch, and put fishing on some sort of a program to be sustainable, might, just might get support.

It is not necessarily liked, but desperate measures seem to be needed to revive european fishing, otherwise there will be no commercial fishing within a few years.


Factual material about by-catch managment in Europe makes Australian northern fisheries management angelic in comparison,not to mention some of the great inventions developed locally in the NT to improve by catch managment, which seem to operate very effectively.

In Australia the fishery is not necessarily that bad [although previously at least one - the orange roughy fishery was nearly fished to extinction, until changes were made], but recent declarations of fishing exclusion zones around the continental areas of Australia have also been met with a harsh response from parts of the fishing industry here.  Yet there is reasonably strong evidence that exclusion zones can actually improve nearby areas as populations grow and spill over into areas outside the exclusion zones.  Yes, I have considerable sympathy for a few players who have been fishng responsibly and may have their livelihoods severely screwed up - they need to be assisted in some sort of transition.

BUT we must avoid the horrible demolition of fishstocks that has occurred in European waters over the past 50 years, and to start now to acheive a sustainable Australian fishery.

Silent Spring - 50 Years Old


http://www.abc.net.au/environment/articles/2012/09/25/3596835.htm?WT.svl=featuredSitesScroller

This link takes you to an article especially pertinent today, the 50th anniversary of the publicaton of Silent Spring by Rachel Carson.

Many argue that was the birthday of the modern environment and conservation movement.  The book chronicled the role of DDT in the environment and the damage it was causing from unprincipled use.

DDT is a very effective agrochemical and still has uses today, particularly when impregnated in mosquito bed nets, for malaria control.........it is a great option that really works.  It is just that, in some ways like the use of glyphosate today, DDT was used for everything!  And society did not know enough about the problems that arose until afterwards, and it was hard to get people to listen.

And then came the book Silent Spring.  A slim volume, and I read it, in the mid 1960s studying agrochemical use as an undergraduate in an ag science faculty.  It was a game changer.

It is still in print, and still worth reading if you have not done so before..

It is true to say, the genesis of the environmental movement can be traced to that book release.

Landsat is Forty Years Old

If you use Google Earth, or any of the other images generated from satellites there is a strong chance that some of these come from the Landsat group of imaging satellites.

A standard procedure for many in the agricultural and environmental fields is use of these images for a wide range of purposes.  There are other systems eg SPOT which is French, but Landsat was the first and still is a major source of images.

The first Landsat satellite went into orbit 40 years ago on July 23, and during the past four decades, a series of seven different "birds" have trained a watchful eye on Earth from just about the most wicked vantage point around.

The program's youngest eye in the sky, Landsat 7, has been flying since 1999 and will be joined next year by the next-generation Landsat Data Continuity Mission satellite, or LDCM. The LDCM features up-to-date thermal infrared sensors and land-imaging equipment that will make it a full-blown orbiting observatory.

The Earth observation program was created at the urging of US Interior Secretary Stewart Udall during the Johnson administration -- Udall had seen a photo from space of pollution spewing from power plants in his home state of Arizona and saw the potential for learning about our own planet that seeing it from a distance held.

There are some classic images on the site here -http://news.cnet.com/8301-17938_105-57477494-1/landsat-at-40-images-from-the-longest-running-eye-in-the-sky/?tag=nl.e703

We tend to take satellite imagery for granted now, but it is only forty years since any existed.  And the image quality has improved very dramatically over this period.  Some amazing photos are around.

Climate Change and Silent Spring - A Media Relationship?


Frank Graham Jr., field editor of Audubon magazine, marks the 50th anniversary of Rachel Carson’s classic book, Silent Spring, by examining the vitriolic attacks leveled against Carson in the 1960s and pointing to troubling parallels with the assaults on climate scientists today. Critics from industry and agriculture dismissed Carson as a mouthpiece of “a vociferous, misinformed group of nature-balancing, organic-gardening, bird-loving, unreasonable citizenry.” But as Graham notes, Carson’s groundbreaking analysis of the harmful effects of DDT and other pesticides led to important bans on dangerous chemicals. Read the article.  This was published as an intro to a Yale Environment online blog.

It is sobering to think of the effects that Silent Spring has had over the past 50 years.  From distaste and absolute rejection by many initially, to now generally accepted as mainstream science, and bringing some big changes in environmental behaviours.

As the author alludes, is the current rejection of much of the science of climate change essentially the same?

I am not so sure, as we have had in the past 50 years the creation of media "thought leaders" [ or should it be media d***heads" ] who have significant influence over much of public opinion, and at times who espouse some strange causes.  Where they have influence, dispute over views often rules.  Then there is the rise of instant experts without specialised training or considerable experience in the science areas who cloud ideas, and pander to those who are tending to disbelieve the science.  And then there is inertia, NIMBY thinking and the long time frames for effect........remember "Apathy Rules".


The role of the media is far greater today than when Silent Spring was published.  I am not sure we have yet seen any serious embrace of the results of scientific endeavour on climate change in mainstream media, to really convince the public, although the scientific media certainly has.  And with much of the public disinterested and as yet unaffected, change might be slow for some time.


In Australia as elsewhere, with various forms of carbon pricing either in place or coming very soon, then will that influence public attitudes, or will they just whinge and not adjust?

Food Security Critical for China

A recent post highlights that Australia is selling off resources to China - land resources for agriculture especially.

[see - http://abovecapricorn.blogspot.com/2011/09/should-australia-be-selling-farm.html ]

Not all are happy over this issue.

China, as distinct from Australia has some clear policies around food security and imports of minerals, with a distinct focus on extra-terrritorial acquistion of the means of production - of both.

See more here - http://qcl.farmonline.com.au/news/nationalrural/agribusiness-and-general/finance/china-aims-for-selfsufficiency/2268434.aspx?storypage=0

In this article Prof Mike Berrell, Director WADEmatheson and Executive Dean, Holmes Institute, Australia, an expert on Chinese business practices says Australia’s lack of strategy and vision for a sustainable agricultural industry, was flagging in comparison to China’s global approach.

He said for the Chinese to be purchasing prime agricultural land outright entails risks for Australia due to loss of control in what is emerging as a global strategic industry.

This would be especially the case if the ventures were 100 percent Chinese invested, he said.

Despite China's recent efforts to reduce carbon emissions, China's current commitment to sustainability does not extend to agricultural practices, he said.

“Joint ventures in the area would be preferable to 100 percent Chinese foreign ownership - the latter of course suits China,” he said. “Australia must be absolutely clear about how such ventures are to move ahead and establish strict guidelines for ownership - perhaps make sustainable agriculture a strategic industry is the same way has China has its “strategic industries”, which fall outside normal investment guidelines.”

A significant issue in this is that most players from China are state owned, effectively an arm of the sovereign government of China. While other parts of the world have previously invested in Australian rural properties and industries, and many still do, [think the UK and the USA] they are almost always privately owned companies, or private individuals, and from countries where government intervention in industry is minimal.

This is a serious issue for Australia, a nett food exporter, with other sovereign countries owning our food production resources.

The image also shows that it is not just China - an example of the options that Singapore is pursuing in a similar fashion.



Should Australia be concerned over the whole theme of extra-territorial agriculture?

Sediment Socks Work Better with Compost

Compost socks

Using a sand filled coil as an environmental salvation tool is quite common. Seen round the streets and building sites these long thin “socks” are a common tool for erosion and sediment management in almost any site where sediment movement could be expected.

Traditionally, it was sand that went into these socks.

But performance can be enhanced, by the simple change from sand to compost or fine pasteurised mulch products. That is a simple and easy change to make, and it may cost nothing different.

An even better option can be to add some of the bioremediation type products available that have oil and hydrocarbon remediation attributes. There are a few brands available, but an easy one available in Australia is Enretech -1 , a powdered product that can be added to the sand or even the mulch mix.

Fine hydrocarbon materials, metals and rubber , commonly moved off roads in wet weather will be trapped by the socks and the hydrocarbons bioremediated, avoiding their movement into waterways.

The mulch is superior to sand in capturing the hydrocarbons, and as good or better in slowing sediments in general.

And costs about the same as sand filled socks.

So.........think about the issue and make the switch to a better sediment sock!





and are applicable almost anywhere around the world.

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.

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

when Australian stories make it to this level, it is considered big news.

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.

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!!

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.

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.

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.

Erosion and Sediment Control with Recycled Organic Waste - Berms

The following is very pertinent to the Top End of the NT today, as we experience a major 100mm per hour storm across the Dariwn region.

Where is your soil going today??


Erosion and sediment control, particularly on civil construction sites often seems to start and end with using a silt fence.

While silt fences can be effective, to be so, they require correct installation, and ongoing maintenance. While there are machines to install silt fencing [yes, they do exist!] rarely have I seen one in Australia, and especially on smaller civil works sites, they are, as they say, as rare as hen’s teeth!

Installing a silt fence is a tedious job, particularly the preparation of the footings, in which a lower area is buried, as well as refilling the trench. Mostly, and somewhat sadly, it is often done poorly, and the silt fence is often relatively ineffective.

In Australia with high summer storm rains, and especially so in the tropics, it is quite common to see a silt fence struggle with high rainfall intensity, and they sometimes breach. There are other options that can be simple and easy to install, and repair if necessary.

Top among the options is using a mulch or compost berm or contour bank. Many regions have mulched green waste available, and creating a berm is relatively simple using readily available on site equipment such as a bobcat or small backhoe. Accessing the greenwaste is often through the local council, or sometimes even using on site available cleared green materials can be useful too.
Ideally, pasteurised mulch is the preferred material, with coarse materials suitable. Ground woody waste, even small woody branches are usable. However, where pasteurised mulch is NOT available, unpasteurised mulch can do, although there will be a need to spray and kill any weeds that emerge within the berm – glyphosate is the normal option. Plants developing from the pasteurised mulch are very slow to almost none, although a few plants might be expected from blown in seeds, after a while.

There are some excellent resources on line, but the simple plan is to develop several berms across a slope, on the contour. They should be lightly keyed into the ground, often by building on a ripped base area or similar simple disturbance. Unlike an earth bank, they are supposed to be porous........just that all the water does not flow through at once, and sediment is collected and deposited along the way.

http://www.creativeearth.net/stormwater.html - shows how to build a system


When the project is completed, the berm can then be used as part of the organic materials often used on site as part of the landscaping, or often left in place in small drainage lines to continue to function until there is improved cover on the nearby soil areas.

They work extremely well, are cheap to construct and maintain, and VERY environmentally friendly!

Can Energy be Less Black in Australia?

Australia's energy markets, their regulation and development might be in for some serious challenges it seems, right at the nub of change - policy intervention.

Australia has much of our energy production from coal, including some from particularly dirty brown coal. These are all on one side. Shall we say the brown, or maybe black corner.

Then there are the new energy producers, with renewable energy in various forms, but commonly wind in the majority at present, but more alternatives coming, or at worst, gas as the primary energy source. The green corner, you might think.

Lobbying from the black corner has so far been quite successful, with their success relatively undiminished. Even a few more recent successes. There has been a focus on preservation of the policy status quo. BUT.......the green corner is pushing hard, and might be on the cusp of some decent gains.

Read the article here and look at the links. An interesting time is upon us.

Can the politicians yet be convinced that it is within their power to actually do something??

Urban Agriculture - Concepts for 2050

While 2050 might be 40 years in the future, planning and development thinking has already been evolving about what agriculture might be like.

There have been options mulled over including : -
  • agriculture and horticulture as part of green roofs on multi story buildings
  • use of the vertical surfaces of building to have plants growing on the facades
  • use of warehouses to convert to hydroponic production [ currently being done in some rundown city areas in the USA]
  • local community gardens
  • locally reprocessed and used organic wastes and water

and the most recent scenario is even more ambitious.

It is the integration of production, processing and sale of fresh produce including fish farming and potentially some animal production such as chickens and other poultry in an integrated manner in a single facility.

It also potentially offers urban recycling as presumably a facility might also require composts and recycled water.

The link is: -http://www.justmeans.com/Agropolis-Future-of-Urban-Agriculture/30772.html

It is an intriguing concept and it would have many advantages for many cool regions of the world.

It is reproduced below. Read and think........

Last week at the Nordic Exceptional Trendshop 2010, held in Denmark, one presentation took urban agriculture to the next level. A collaboration with NASA, you might even say it launched urban agriculture out of this world, and into the future.

The idea is called Agropolis, a combination grocery store, restaurant, and farm all in one building, employing the most advanced technologies in hydroponic, aeroponic, and aquaponic farming. As it stands, Agropolis is still just a mere idea, with little more than some cool graphics to back it up.

But regardless, Agropolis ushers forth a new wave of thinking about urban food systems.

The team behind the Agropolis concept proposes that this new generation of store would be an ecosystem unto itself, a finely tuned orchestra of parts in balance, that would not only be totally envrionmentally sustainably and friendly, but also just plain producing the freshest food around.

But what would all these innovative, NASA-inspired state of the art hydroponics and other high-tech solutions look like in practice? ............According to the vision of Agropolis, a customer would walk into a store that is covered in green. Vegetables growing on the walls as far as the eye can see. And below the floors one would see tilapia swimming, working in tandem with vegetables in an aquaponic system. You would buy a tomato that was literally just picked, from a plant that you can see in front of you. The store would bring a whole new meaning to local, and one-up the notion of hyper local, since all the food available to eat or buy would have traveled zero miles from the farm to the store. At most, just a few steps.

It all sounds grand, and more than a little space-age. But the challenge given to the team that came up with Agropolis wasn't entirely outside reality: Create a farm without relying on arable lad. As the Earth's healthy soil and other resources dwindle, it may not be out of the realm of possibility that a system like Agropolis be needed, particularly in urban areas.

And while urban agriculture has come a long way, incorporating all kinds of creative and innovative ideas and technologies, in order to make it work on a large and global scale it may be time for something as futuristic and high-tech as Agropolis. But imagine if, in fifty years, or some other future point, our grocery stores did include built in farms, how our relationship to food would change. For one thing, the variety of food we eat might change--are there some vegetables and fruits that can't be grown using these artificial systems? Would we only eat tilapia, and no other meat?

Other vertical and urban farm project proposals include a variety of "staple" crops and animals that all work seamlessly together. But is biting into a fresh, hydroponic, LED light feeding tomato really as good as getting one from your local organic farmer who's tomatoes ripen in the sun?

What will the foodies of this imagined future look like?

In this brave new world of urban agriculture, one this is certain: While Agropolis insists that the store/restaurant/farm will be a sort of ultimate consumer experience, it'll be a much different experience than what we have access to now.
