What is it about?

Land is one of the few productive assets owned by the rural poor, and almost all households engage in some form of agriculture. Over 2000-2010 the rural poor on degrading agricultural land increased in low-income countries, and in Sub-Saharan Africa and South Asia. Although degradation threatens the livelihoods of the poor, this interaction is complex and conditioned by key economic, social and environmental factors. These factors also limit the poverty-reducing impacts of economic growth and economy-wide reforms. A comprehensive development strategy requires investments that improve the livelihoods of affected populations and regions and facilitate outmigration in severely impacted areas.

Why is it important?

Two of the United Nations’ Sustainable Development Goals (SDGs) are to “end poverty” (Goal 1) and to “strive to achieve a land-degradation neutral world” (Goal 15.3), which requires that any land degradation is fully offset by restoration of degraded land. A fundamental question is whether these two SDGs are compatible. Ending global poverty while at the same time balancing land degradation with restoration suggests that there may be potential tradeoffs in attaining these two SDGs. Accurately assessing these tradeoffs will require, in turn, a clear understanding of the relationship between land degradation and poverty. Despite decades of research, it is not obvious that such a consensus view exists in the literature.

Perspectives

I first started working on issues of land degradation and poverty over 30 years ago. As I have gone on to research other important environment and development problems, it has been a pleasure to review different inter-disciplinary perspective on land degradation and poverty and to try to comprehend the main contributions to our understanding of this complex problem.
