Climate change has produced a growing demand for renewable solutions and accordingly the need for suitable areas of land and ocean: Cultivating food crops and plants for biofuels, wind turbines, solar and biogas plants – it all takes room. How should agricultural land be used in the future? What are the ideal locations for balancing profits, costs and environmental risks? Through regional case studies e.g. on solar parks in Northern Africa, clearing forest areas in Brazil, and use conflicts in Northern Germany, the CEN is exploring new approaches to land use. Here the focus is on ensuring stable supply chains, on protecting nature and climate – and on conflicts and potential collaborations between developing and industrialized countries.
