Economics of Land Degradation and Improvement - A Global Assessment for Sustainable Development

Land degradation is occurring in almost all terrestrial biomes and

agro-ecologies, in both low and high income countries. However its impact is

especially severe on the livelihoods of the poor who heavily depend on natural

resources. Despite the severe impact of land degradation on the poor and the crucial

role that land plays in human welfare and development, investments in sustainable

land management (SLM) are low, especially in developing countries. This chapter

summarizes the results from global and regional levels as well as 12 case study

countries. The chapter also draws conclusions and implications for taking action

against land degradation. Land degradation stretches to about 30 % of the total

global land area and about three billion people reside in degraded lands. The annual

global cost of land degradation due to land use/cover change (LUCC) and using

land degrading management practices on static cropland and grazing land is about

300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22 %) of

the total global cost of land degradation. Only about 46 % of the cost of land

degradation due to LUCC which accounts for 78 % of the US$300 billion loss

is borne by land users and the remaining share (54 %) is borne by consumers of

ecosystem services off the farm.
