Here are a few example of topics available to study and research:
Example of an introduction to the study task "The Living Soil":
One of the main problems of industrial farming is that the soil does not figure as an important and valuable resource. It does in the physical sense. All farmers are keenly aware of their soils' ability to retain water and nutrients or the problem of having clayey soils where waterlogging kills the roots. But industrial farming is not concerned with creating life in the soils - it is not an issue. Their problem with soils is that the chemical fertilizer they spread out is washed out too fast because of sandy soil. In such cases they might add some organic manure to the field, although this is very seldom done on the huge industrial scale farms. They simply cannot get the amount of manure needed.
Not building up a healthy soil is a short term strategy, which has been profitable in the immediate run for these large farmers. But the rest of us are suffering the consequences. The food has become less nutritious, because the plants are only receiving the nutrients they get from the chemical fertilizers, and since this is dictated by profits, these are held to a minimum. People living further downstream from such fields suffer from the erosion caused by a lifeless and unprotected soil, because more soil is washed away. This leads to floods as river beds are raised by the sediments, the lifetime of hydropower plants being shortened because the water reservoir gets filled up with sediments and to nutrients being led out in lakes and seas, where this creates pollution as algae grow, accumulate and rot.
The climate is also suffering, because a lifeless soil does not store carbon as a healthy soil would do. Instead, the little organic material that was in the soil is decomposed, meaning that the little carbon that was still left is leaking to the atmosphere and contributing to global warming.
The world needs - actually requires - that farming is transformed into being an activity that not only produces food in the short run, but also in the long run by ensuring a living soil and by allowing for a healthy build-up of carbon in the soils, thus reducing instead of contributing to a warmer world.
