There is a grave environmental crisis in air quality (life expectancy in polluted northern cities is five and a half years lower than in the cleaner south), water and soil (one survey showed that 10 per cent of arable land was unsafe to grow crops on).
Soil organic carbon (SOC) in arable organic farming depends on inputs in crop residues, green manure, catch crops and animal manure.
While recent policy interventions (such as the Good Agricultural and Environment Condition requirements of the CAP, and the EU Soil Thematic Strategy) have reduced the rate of soil loss in the EU by an average of 9.5 % overall, and by 20 % for arable lands, the study finds that four million hectares of EU croplands have unsustainable rates of soil loss (more than 5 tonnes per hectare per yeSoil Thematic Strategy) have reduced the rate of soil loss in the EU by an average of 9.5 % overall, and by 20 % for arable lands, the study finds that four million hectares of EU croplands have unsustainable rates of soil loss (more than 5 tonnes per hectare per yesoil loss in the EU by an average of 9.5 % overall, and by 20 % for arable lands, the study finds that four million hectares of EU croplands have unsustainable rates of soil loss (more than 5 tonnes per hectare per yesoil loss (more than 5 tonnes per hectare per year).
The FRO2 gene is common to all plants, so boosting its expression in food crops or finding variants that thrive in poor soils could be important for increasing crop yields in the face of population growth and global warming's threats to arable land.

Fortunately, Wamelink has been raising crops in simulated Martian soil for years and found that it's surprisingly arable — he's been able to grow potatoes, carrots, green beans, and tomatoes, as well as introduce earthworms to make the soil more fertile.
Of course, this still doesn't fill in many missing bits of information (such as the knowledge that even if parts of Canada or Siberia get warmer, they will not necessarily have arable soil, or growing seasons of the proper duration (i.e. number of months with a minimum amount of sunlight per day) to make them viable for crops.
The natural variation that has led us out of the Little Ice Age has a bit of frosting on the cake by land use; and, part of that land use has resulted in a change in vegetation and soil CO2 loss so that we see a rise in CO2 and the CO2 continues to rise without a temperature accompaniment (piano player went to take a leak), as the land use has all but gobbled up most of the arable land North of 30N and we are starting to see low till farming and some soil conservation just beginning when the soil will again take up the CO2, and the GMO's will increase yields, then CO2 will start coming down on its own and we can go to bed listening to Ave Maria to address another global crisis to get the populous all scared begging governments to tell us much ado about... nothing.
Importantly, depletion of SOC in conventional agricultural fields is now thought to be an important factor constraining productivity as many arable soils have suboptimal concentrations (Lal 2010).
Comparison of Allotment and Agricultural Soils The remarkable contrast in soil quality indicators (higher SOC, C: N, TN and lower BD) between allotments and arable fields reveals the effectiveness of management achieved by own - growers.
With falling water tables, eroding soils, and rising temperatures making it difficult to feed growing populations, control of arable land and water resources is moving to center stage in the global struggle for food security.
With food scarcity driven by falling water tables, eroding soils, and rising temperatures, control of arable land and water resources is moving to center stage in the global struggle for food security.
To take just one fairly representative example, in the classic Rothampstead experiments in England where arable land was allowed to revert to deciduous temperate woodland, soil organic carbon increased 300 - 400 % from around 20 t / ha to 60 - 80 t / ha (or about 20 - 40 tons per acre) in less than a century (Jenkinson & Rayner 1977).
