Putting Economic and Environmental Sustainability Hand in Hand to Protect Our Lands
MetadataShow full item record
Land degradation is an underestimated global concern with far-reaching implications affecting the ability of land to provide food and incomes. Globally, a large portion of the vulnerable human populations—the rural poor—live on degrading and less-favored agricultural lands without market access. Heterogeneous solutions that ensure both economic and environmental sustainability are needed at multiple scales. On a policy level, awareness of land and soil degradation is increasing. Last year all countries adopted a set of goals as part of the 2030 Agenda for Sustainable Development. The specific goal on land degradation includes a commitment for countries to take steps to achieve a land-degradation neutral world. This commitment is universal; it will apply to developed as well as developing countries and covers lands with sufficient rainfalls for agriculture as well as drylands across political borders. However, a recent publication claims ‘the end of desertification’ and calls for a more nuanced approach to the serious problem of global land degradation that moves away from the emotional rhetoric of expanding deserts and sand-covered villages, forcing people to migrate into an uncertain future.1 Such doom and gloom stories dominated international discussions in the late 20th century and provided the arguments for the establishment of a UN Convention to Combat Desertification, which is now specifically addressing this issue. Others have countered this direction of thoughts with a more optimistic view of how populations can survive by building on traditional knowledge in a new paradigm for people, ecosystems, and development.
