Paving farms

On our way to Bob Stewarts farm in Yorkville, Illinois, we see many newly "developed" areas with huge houses (sometimes referred to as McMansions in the US) with generous compounds. This on some very good agriculture land.  Bob tells us that he sold some land for that development and that he buys more land down in Farmer City, far away from the urban sprawl. It reminds me of the discussion in Brazil, where the expansion of soy beans is blamed from de-forestation, not because the soy beans are grown in the rain forest, but because soy production pushes cattle breeders from expensive fertile land into the cheap Amazon land. Ultimately, land resources are limited, and when we pave fertile land, some other land will be needed for farming. Also, most big cities are located in rich farm areas - which is why they became big in the first place, unless they were trading towns - and one acre of good land, may need to be replaced by three or four acres of less good land.

 During the past 30 years, much of America’s most fertile farmland has been lost to wasteful development. The National Resources Inventory   The NRI, conducted by the USDA Natural Resources Conservation Service (NRCS) in cooperation with Iowa State University’s Center for Survey Statistics and Methodology, is a survey of the nation’s non-federal lands that tells the story of farmland loss by the numbers. The most recent NRI, covering the 25-year period between 1982 and 2007, reveals that more than 23 million acres of America’s agricultural land have been lost to development—an area the size of Indiana.

 I have called for an international soil convention several times before. Unfortunately it doesn't seem to be on the agenda for the upcoming Rio +20 event.

Your 200 square meters of concrete and asphalt

One of our environmental footprints is the sealed area of the planet:

The total sealed soil surface of the EU area in 2006 was estimated to be around 100 000 km² or 2.3 % of the EU’s territory, with an average of 200 m² per citizen. Member States with high sealing rates (exceeding 5 % of the national territory) are Malta, the Netherlands, Belgium, Germany, and Luxembourg. Furthermore, high sealing rates exist across the EU and include all major urban agglomerations, and most of the Mediterranean coast. The latter experienced a 10 % increase in soil sealing during the 1990s alone.  Assuming an unabated linear trend, we would convert, within a historically very short time frame of just 100 years, an amount of land comparable to the territory of France and Spain combined. Moreover, it is not only the absolute land take figure that matters but the spatial distribution and the value and availability of the land taken. For example, settlement areas cover 5 % of Austria’s total territory, but this figure soars to around 14 % when Alpine areas unsuited to urban or infrastructure development are excluded. When looking at the conversion of agricultural land, land take matters even more as the share of arable land in Austria is about 16 % only. In the case of the Italian Emilia-Romagna Region, some 95 % of the land take between 2003 and 2008 occurred in the fertile plain soils that cover only half of the Region. (from the Guidelines on best practice to limit, mitigate or compensate soil sealing from the EU)
I wrote about this in a post just a few days ago:

Paving the land - and taking it back again

The EU report above has some good recommendations. 

Limiting soil sealing means preventing the conversion of green areas and the subsequent sealing of (part of) their surface. The re-use of already built-up areas, e.g. brownfield sites, can also be included in this concept. Targets have been used as a tool for monitoring as well as spurring progress. Creating incentives to rent unoccupied houses has also helped in limiting soil sealing. Where soil sealing does occur, appropriate mitigation measures have been taken in order to maintain some of the soil functions and to reduce any significant direct or indirect negative effects on the environment and human well-being. These include using, where appropriate, permeable materials instead of cement or asphalt, supporting ‘green infrastructure’, and making wider use of natural water harvesting systems.

But it also introduce another version of of the idea that we can "compensate" or "offset" the effects of our behaviours. So, in a similar way as we can 'offset' our carbon emissions by planting trees in Africa, we can 'compensate' soil sealing: 

"The eco-account system is based on determining the ‘ecological costs’ of development projects involving soil sealing through the attribution of eco-points. Developers have to ensure that compensation measures of equal value are being carried out somewhere else. Ecopoints are acquired at officially authorised compensation agencies, which are responsible for their attribution and redemption and for overseeing the system."

So next step is that we can pay for re-claiming land in Africa for us to continue building high-ways. A strange world indeed.

Paving the land - and taking it back again


"Restoring to fertility land covered with concrete is an enormous task, but not an impossible one. So, Lorenza Zambon, actress and gardener, tells the story of a couple in Turin, Italy, who decided to give to their children a patch of fertile land as a gift. It was a lot of work; concrete had to be cut and broken to pieces and the rubble carried away. Then, restoring the fertility of the soil took truckloads of dirt, charcoal, and more. Zambon doesn't tell us how long the task took nor how much it cost, but surely it was slow, messy and expensive. It was also a subversive idea: in the generally accepted view, paving the land means "developing" it, and that means making money. So, destroying property to restore the fertile soil is something that nobody in his/her right mind would - normally - do."
writes Ugo Bardi on his blog post about the increasing encroachment on agriculture land by roads, houses etc. It is very hard to get accurate data for exactly how much land is paved over or "built" in the world. Data from Denmark looks like this. 

Danish land use (ministry of environment 2004)
 4.1 %, 4.3 % and 4.4 % of the EU territory was classified as artificial surface in 1990, 2000 and 2006 respectively. This corresponds to a 8.8 % increase of artificial surface in the EU between 1990 and 2006. In the same period, population increased by only 5 %. In 2006 each EU citizen disposed of 389 m² of artificial surfaces, which is 3.8 % or 15 m² more compared to 1990. Unsustainable land use trends can be observed in Cyprus, Denmark, the Netherlands and Portugal where land take is growing considerably faster than population growth. Furthermore, there are several new Member States also affected by unsustainable land use trends due to continuing land take and at the same shrinking populations. Policy targets for land take. Quantitative limits for annual land take exist only in six Member States: Austria, Belgium (Flanders), Germany, Luxembourg, the Netherlands, and the United Kingdom. In all cases the limits are indicative and are used as monitoring tools. This can be read in a recent EU report. I write more about this report in the post EU farm land increasingly sealed. 

In Garden Earth I write:

Roads and petrol stations—the crops of the modern times

The statistical basis for assessing how much land human beings have taken in direct use for buildings, roads, etc., is surprisingly weak. Literature quote figures from 1.5% up to 9%. In Sweden 3%, 1.29 million hectares of the land, is built on in some way. Land for housing was 29% of this; roads, railroads and airports 31%; industries, etc. 11%. Of course, Sweden is sparsely populated. In the county of Stockholm 15% of the land is built upon whereas in the northernmost county of Norrbotten only 0.6% of land is built upon. There were 550,000 kilometres of roads (some 60 metres per person) covering 345,000 hectares of land (SCB 2004). In the more densely populated Denmark, human infrastructure is calculated to cover almost 20% of the land area (Danish Ministry of Environment 2005). During the 1960s, 7% of European farm area was encroached upon by roads and 15% of the agriculture land of Great Britain was built upon (Montgomery 2007). By 2010, the United States lost almost 10 million hectares, more than 2.5% of farmland, to human infrastructure since 1950 (Talberth et al. 2007). Eastern United States has a larger proportion of its total area (4–5%) in urban and suburban landscapes than in other regions (H. John Heinz III Center 2008).

We need to do something with the ongoing encroachment of agriculture land by built infrastructure. It is scandalous that soils are not protected by any international conventions. As far as I understand it is not even on the agenda in the upcoming Rio + 20 meeting.
Time for a soil convention!

Update 19 April:
Apparently the EU Commission released some guidelines about "soil sealing"

Soil: wrong side up

"Author Joseph Kinsey Howard describes a spring day in 1883 in North Dakota when John Christiansen, a Scandinavian farmer, looked up while plowing a field to discover an old Sioux watching him. Silently the Sioux watched as the prairie grass was turned under. The farmer stopped the team, leaned against the plow handles, pushed his black Stetson back on his head, and rolled a cigarette. He watched amusedly as the Sioux knelt, thrust his fingers into the furrow, measured its depth, fingered the sod and the buried grass. Eventually the Sioux straightened up and looked at the immigrant. “Wrong side up,” said the Sioux and went away."

This comes from an article by Wes Jackson in YES!
The article is mainly about how to restore the prairies, or rather how to re-invent perennial systems of farming. He concludes:
"As civilizations have flourished, many upland landscapes that supported them have died, and desert and mudflat wastelands have developed. But civilizations have passed on accumulated knowledge, and we can say without exaggeration that these wastelands are the price paid for the accumulated knowledge. In our century this knowledge has restorative potential. The goal to develop a truly sustainable food supply could start a trend exactly opposite to that which we have followed on the globe since we stepped onto the agricultural treadmill some ten millennia ago."

Clearly soil erosion has caused the collapse of many civilizations. As I write in Garden Earth:

Environmental degradation has followed man since his first attempts to farm, well even before farming. Also hunters caused substantial degradation e.g. by the extermination of large mammals in North Americas or many bird species in the Pacific. Soil erosion is one of the most prevalent and also one of the most harmful kinds of environmental degradation. It was an issue of concern for rulers of ancient Greece as early as the sixth century B.C. The lawmaker Solon proposed a ban on cultivating hillsides in order to prevent erosion. The ruler Peisistratos rewarded peasants for planting olive trees instead of cutting down forests and grazing livestock. Two-hundred years later, Plato wrote of land devastation taking place in Attica:
“...in the primitive state of the country, its mountains were high hills covered with soil, and the plains, as they are termed by us, of Phelleus were full of rich earth, and there was abundance of wood in the mountains. Of this last the traces still remain, for although some of the mountains now only afford sustenance to bees, not so very long ago there were still to be seen roofs of timber cut from trees growing there, which were of a size sufficient to cover the largest houses; and there were many other high trees, cultivated by man and bearing abundance of food for cattle. Moreover, the land reaped the benefit of the annual rainfall, not as now losing the water which flows off the bare earth into the sea, but, having an abundant supply in all places, and receiving it into herself and treasuring it up in the close clay soil.” (Plato Critias)
If not dramatic collapse, so at least the slow decay of most civilizations can be traced back to soil erosion and wasteful agricultural practices. It is a sobering insight that there are very few agriculture systems that actually have proven to be really sustainable, and for many of those it is thanks to external factors that they are sustainable, not thanks to the ingenuity of humans. The fertility of the Nile valley and other flood plains is mainly a result of erosion up stream bringing every year new soil and new nutrients downstream. David Montgomery[1] states in Dirt, the Erosion of Civilizations, that most historic cultures lasted between five hundred and one thousand years. They start off with fertile soils created by natural processes. Fertile soils in hills with good rainfall are brought into cultivation as population increases, but soil erosion makes fertility fall. Marginal lands are taken into cultivation where fertility plummets rapidly and finally the whole civilization collapse, the area is depopulated until nature replenishes the soils again. He shows that Schwarzwald (Black Forest, today dominated by forests as its name indicates) in Germany has gone through three such cycles (Montgomery 2007).

Carbon Markets - a corporate Trojan Horse?


Carbon farmers

Both the United Nations Food and Agriculture Organisation, FAO (2003), and the World Bank promote that carbon emission trading should encompass also carbon sequestration (sinks) in soils, i.e. that farmers could get paid for increasing soil organic matter. The carbon sink capacity of the world's agriculture and degraded soils is said to be 50% to 66% of the historic carbon loss from soils or some 42-78 Gt of carbon (FAO 2009). Measures in the farm sector for mitigation of climate change are among the cheapest measure to take, and in many cases, they also lead to other environmental improvements (reduced water pollution). Increased soil organic matter also leads to richer soils; to soils that can keep water and resist erosion longer. A major hurdle is that there are so many farmers and their conditions are very diverse;  it is very hard to determine exactly how much carbon a farmer will capture if he or she does this or that. To measure it on an individual level will be very costly. A new scenario emerges where farmers in developing countries can sell their services as carbon farmers to governments and companies in the developed countries. This could become a business replacement for aid, or a way to compensate developing countries farmers for absurd subsidies to their competitors in developed countries. 

But it also means that a larger part of their activities are integrated into the world economy, in the market economy. It can also be seen as a new frontier of exploitation, where the rich countries will use the land in developing countries as "dumping" ground for their waste, which is what this eventually amounts to. 

I recently wrote a report for UNEP where I had drawn this graph: 
Carbon changes in the soil
download report



It is important to keep in mind that once farmers have got compensation for the carbon stored in their sold through the means of carbon credits, they are forced to maintain practices that keeps the carbon there. One could say that they actually don't own their soil organic matter no more.They don't control how they manage their own soils.

Australia has already a Carbon Rights Act: 
The Carbon Rights Act 2003 establishes a statutory basis for the ownership and protection of carbon rights, in order to facilitate trading. It enables a carbon right to be registered on the land title as a separate interest in that land. The Act provides that a carbon right may be registered with the consent of all parties having an interest in the relevant land.....Owning a carbon right is like owning land. The title guarantees who owns the land (or carbon right). The market will determine what the land (or carbon right) is worth, based on a wide range of factors including how the land is used.

In this way, carbon payments can become a Trojan horse for large scale corporate take over of the land.

Organic farming as a strategy for a new economy



Introduction
This paper explores the evolution of the modern agri-food system and in particular, how it has been shaped by the market economy, industrialisation and cheap fossil fuel. It concludes that some of the principles of organic farming are incompatible with the logic of the market economy and the industrial society. Therefore, the organic movement should look for strategies that challenge the prevailing paradigms, and build alternative economies.

Farming has been shaped by cheap fossil fuel and the market economy.
Farming systems are largely shaped by the ecological and social conditions under which they develop; they also influence these conditions. It was the shift from a hunter and gather society to an agrarian society that lead to the initial stratification of society in rulers and oppressed, to private property and to the city and the state. The simple agrarian equation was always that farmers must produce more energy as food than the energy they spent on it. They must produce energy for themselves, for young (reproducing the labour force), old and sick dependants, for some other tradesmen and for the rulers, who offered protection against taxes or forced work. For a long time this energy equation remained the same. Gradually, through technical innovations, productivity could increase and new lands could be tilled, thereby allowing a slow increase in population. All in all productivity per worker didn't increase so much; slash and burn farming, almost without tools, is mostly as productive as farming with oxen and a plough[1]. Three things, all linked to each other, changed this dramatically: the emergence of the (capitalist) market economy, industrialisation and fossil energy.

Industrialism caused a fundamental change in social relations where the family unit ceased to be a unit of organised production and becomes a unit of organised consumption. Industrialism was also a way to largely expand exploitation of labour and nature. Through the combination of the market economy and industrialism, externalisation of environmental and social costs in time and place was possible - and profitable. This lead to that producers which internalised costs, simply could not compete, be it peasant farmers, artisans or corner shops. This was further augmented by that industrialism also brought in fossil fuel and thereby, seemingly, broke the ecological limits of the economy. The power in society shifted from those that controlled solar collection on the ground (landlords) and human masses (the state and landlords together) to those that controlled the new energy sources (fossil fuel) and put them into work for trade or industrial production - the industrial capitalist. It lead to the emergence of the modern society where more and more aspects of life is regulated by markets; where "growth" is seen as something inherently good or essential; where world population has exploded, where nature is merely seen as a dumping ground and a store of raw materials; and where one's wealth is built on exploitation of fellow humans and nature.

Markets existed since a long time, but up to some hundred years ago, societies were not "market economies". Ancient elites didn't earn their money from markets but from conquest (robbery) rents and taxes. The role of markets for distribution of goods was not dominant, very little food was bought or sold, and there were no markets for land or labour. Farmers were largely shielded from competition in the modern sense. Grain didn’t become a fully tradable commodity until the end of the 19th century in Asia. The big shake up came with the introduction of fossil fuel and industrialisation. Improvements in transportation technology, in particular steamships and rail-roads were both a driver and prerequisite for increased trade. In 1870, a bushel of wheat cost 60 cents in Chicago and the double in London. By the end of the century transport costs, and thereby the price difference, had shrunk to 10 cents. Somewhat later, and in particular after WWII, fossil fuel was also applied in the farm sector itself by the introduction of threshers, pumps for irrigation, tractors and last but not least fertilizers, adapting to the ways of the factory.

The introduction of markets affected every aspect of the farm sector. Now, village life, culture and religion, which earlier both controlled and assisted in farming, became "obstacles to development", because they stood in the way of the market logic. Land, water and forests were gradually transformed from commons to tradable commodities. Farmers are no longer reproducing their production system. They buy seeds and breeds in the market; they don't have to take care of the reproduction of the soil, because they can compensate that with buying chemical fertilisers. They don't have to take care of the balance between nature and what humans take away. The total biological productivity per hectare remains much the same, but we take a higher and higher share of that production, e.g. by transforming grains to have less roots and straw and more kernel; by exterminating weeds and wildlife in the fields and by not allowing the soil to naturally regenerate.

The production per agriculture worker in the most advanced economies have reached 2,000 tons of grain per man year, while in historical times it was just a few tons; an increase in labour productivity by thousand times. But in many parts of the world, the labour productivity is largely the same as it was hundred years ago, while the price of food has decreased tremendously[2]. The average value produced by a farm worker is just above 100 dollars per year in the poorest countries and some 40,000 dollars per year in France. And the gap in productivity between the rich and the poor is widening

Labour productivity in modern farming can largely be explained with the command of energy resources. The modern farmer is de facto commanding a mass army of "energy slaves"; a barrel of oil represents the energy of 25,000 hours of human toil i.e. 14 persons working a year with normal Western labour standards. The energy efficiency in modern farming is considerably lower than in pre-industrial farming systems. Our ancestors would have starved to death if they had had as bad energy ratios as our food system; in industrial countries between 10 and 15 times more energy is used in the food system than what is contained in the food we end up eating.

With cheap global transports and a rather liberalised trade, farmers in developing countries, having access to almost no energy resources, are supposed to compete with colleagues in the developed countries that use energy resources corresponding to hundreds of labourers. Through perverse subsidies and various trade and food policies, economics and rules are bent in favour of the farmers in rich countries. Despite a few selected success stories with high value crops (horticulture) or other premium products, such as organic, most farmers in developing countries are losing out in the competition. Many of the least developed countries have gone from food exporters to food importers in a few decades as a result of these unfair relationships. The same development affects many small farms in developed countries, who can only survive by going into “niches” such as artisan food production or services such as educational farms. There are other troubling aspects of our food system after the farm gate, such as the dominance of a few supermarkets, enormous waste and the deterioration of food quality. These are also linked to the depicted development.

We are in the stage of peak-oil; our wasteful farming system and the use of fossil fuels cause climate change; water resources are depleted; global population has exploded and our ecological footprint is considerably bigger than the planet (and growing by the day). And still, farming is shaped as if labour was the main limiting factor and nature is for free. People in high income countries consume up to 10 times more natural resources than those in the poorest countries. 884 million people lack access to clean drinking water and 2.6 billion people do not have access to running water (UNEP 2010). The differences between rich and poor are increasing over the years;  the richest 2 percent of adult individuals own more than half of all global wealth, with the richest 1 percent alone accounting for 40 percent. Most of the poorest are involved in farming. 
How can anyone claim that our development model is successful, when it fails on so many accounts?

Discussion and Conclusions
There are several features of organic farming that is in contradiction to this development. Most importantly organic farming:
- is based on as closed cycles of nutrients as possible, something that is impossible to maintain with large scale international trade, and in general difficult in a commoditized food system
- builds on natural systems to regulate pests and weed and supply crops with nutrients and is therefore not in favour of system relying on the purchasing of inputs.
- is in principle against the use of finite resources, e.g. fossil fuel and mineral fertilizers
- is committed to fairness, while market imperatives such as competition, rent-seeking and economies of scale are everything but fair, instead they lead to ever increasing gaps between rich and poor.
Organic farming is essentially in opposition, not only to the use of agro-chemicals, but to the whole system that is based on exploitation of nature and of fellow humans. People like myself, have seen it as urgent to transform the farming system into a more benign system without necessarily challenging the prevailing paradigm. A vehicle for doing this has been the "mainstreaming" of organic into mainstream (global) markets and into government policies. That is still a praiseworthy effort, but it comes with a price. I have been a farmer myself and know how it works in the daily life. The power of the prevailing economic system and its ideology is overwhelming. Ultimately organic farmers have to survive, and to survive within the market economy requires submission to the logic of the market; it leads to increased use of inputs in production, externalisation of costs, corporate take-over and business-as-usual approaches. The farmers truest to organic principles are mainly small scale gardeners producing for themselves and lifestyle farmers. They can be true to the organic ideals not because of their moral superiority or higher skills, but because of their autonomy from the market forces.

In theory, full internalisation of costs (such as fees for nature resource use and waste) and compensation for ecosystem services (such as carbon credits or landscape payments) would allow organic farmers to compete "fairly" with non-organic. But the industrial model is based on externalisation of costs. This is also the reason for why there is such a resistance to internalisation of costs from those that profit from the system, be it internalisation of social costs or environmental costs. In a complex system such as farming, internalisation of all social and environmental costs and compensation for ecosystem services would only be possible with very extensive and detailed regulations. Just look at the EU agri-environmental programs which are just a very small step in that direction. Such a system would probably still be neither fair nor efficient, and would in many ways represent a control of farms more sever than under Soviet rule.

There are two strategies to follow: One is the strategy for individual autonomy in the same way as peasants have related to the market for centuries, by limiting their dependency of inputs for production and reproduction of the system, such as fertilizers, paid labour and credits. This "peasant strategy" is not only a feature in developing countries, but is also prominent in many farms in developed countries. It coincides with prominent aspects of organic farming, especially the idea that production shall be based on local resources. It is a strategy based on the understanding that a total integration in the market system will be devastating. While autonomy can be appealing, it also easily leads to isolation both mental and social. Therefore, pursuing individual autonomy has limited ability to change the bigger picture.

Another strategy is based on building new economic relations, which gradually can replace the capitalist market economy. I am proposing systems in the tradition of cooperatives, communities and villages; self-organised local and global societies. Models that break free from the dichotomy between state and the market, which represents a false choice we are supposed to make. It is about lifting autonomy to another level, from a personal strategy to a local and global community strategy. In the same way as the capitalist society developed parallel to, and sometimes in violent opposition to, the feudal society, another society will have to grow, stealthily, beside the market logic. It has to be combined with a change in values and paradigm and aim at an economy where man's wealth does not result in nature's poverty and the poverty of other people. It is incumbent on the organic movement to actively research and test business models that can contribute to such a new social economic order.

EU farm land increasingly sealed

In the European Union (EU) about 1,000 km² were annually subject to land take for housing, industry, roads or recreational purposes between 1990 and 2006. This is exceeding the size of Berlin. About half of this surface is actually sealed by buildings, roads and parking lots.

4.1 %, 4.3 % and 4.4 % of the EU territory was classified as artificial surface in 1990, 2000 and 2006 respectively. This corresponds to a 8.8 % increase of artificial surface in the EU between 1990 and 2006. In the same period, population increased by only 5 %. In 2006 each EU citizen disposed of 389 m² of artificial surfaces, which is 3.8 % or 15 m² more compared to 1990.

Unsustainable land use trends can be observed in Cyprus, Denmark, the Netherlands and Portugal where land take is growing considerably faster than population growth. Furthermore, there are several new Member States also affected by unsustainable land use trends due to continuing land take and at the same shrinking populations. Policy targets for land take. Quantitative limits for annual land take exist only in six Member States: Austria, Belgium (Flanders), Germany, Luxembourg, the Netherlands, and the United Kingdom. In all cases the limits are indicative and are used as monitoring tools.


This can be read in a recent EU report, Overview of best practices for limiting soil sealing or mitigating its effects in EU-27. The reports continues: 
Only very few Member States have defined national policies which explicitly address these issues....In view of rising energy prices, food and biomass production within the EU are gaining impor-tance and the demand for productive soils is growing. Despite several initiatives it can be concluded that soils are not adequately protected in the EU. Soil quality is rarely respected along planning processes and compensation of soil losses hardly realised.
Economic growth is still highly depending on land take and soil sealing (see graph). In order to decouple economic growth from land take and soil sealing, it is suggested to strictly follow the prevent, limit and compensate principle for soil sealing. Several elements of this logic are already being realised in some Member States as described in the section above and in the country profiles of this report. However, limitations to soil sealing are primarily based on voluntary agreements and non binding measures.

The graph shows the area of "artificial surface" per capita. It shows that the artificial surfaces are increasing not only in absolute numbers, but also per person, with a few exceptions (those marked in red). This means that there is certainly no "decoupling" going on regarding soils.

The report calls for EU wide regulations with the logic that "It can be expected that single Member States will refrain from applying stricter regulations to protect their soils from sealing as this could represent a market disadvantage."  This kind of argument is in my view flawed. And if it really is correct perhaps the solution is to change and challenge the market logic rather than to call for EU wide regulations of everything?
The continued sealing and conversion of agriculture land to "built land" is troublesome, and I have written about it before, for instance calling for a soil convention:

Time for a soil convention!

and I explained how delicately we live in:

 ----------------------------------------

The Commission's Soil Thematic Strategy has identified soil degradation, including soil sealing, as a serious problem at EU level. To protect European soils the Commission presented a proposal for a Soil Framework Directive in 2006, with the support of the European Parliament. However due to opposition from some Member States the proposal is currently stalled in the Council.
