– Pressure on available areas for food production leads to high pressure on cultivated soils. We must protect soil better for changed precipitation and runoff conditions to secure land for food production and minimize pollution of surface, drinking water.
– Clear planning for soil management and re-use is critical in retaining the potential value of soils. This requires knowledge of the soils and specialist input to soil handling strategies, and wider understanding of how new developments can be designed to maximise the extent of soil included, the health of that soil and how it can be used to support the community, from green spaces for climate adaptation to local food production.
– In urban environments, quantities of wastes and wastewater are produced, which are assets to increase agricultural productivity and construct soils of gardens, green roofs and green areas. The reuse of treated wastewater in periurban agriculture sets high quality water free for human consumption. It has become mandatory to recognize and preserve urban soil functions to achieve sustainability.
– Based on the concept of regenerative agriculture and agroecology, the Green Revolution of the 21st century must be soil centric, ecosystem based, and aimed at producing more from less, practicing nutrition-sensitive agriculture, and returning some land and water back to nature. It is also important to grow soil C as a farm commodity that can create another income stream for land managers.
