A Global Assessment of Land Quality

The contributors to this book – including soil scientists, geographers, and economists – analyse data on soils, climate, land cover, agricultural inputs and outputs, and a variety of socio-economic factors to provide new insights into three key issues: • the extent to which differences in land quality generate differences in agricultural productivity across countries • how farmers’ responses to differences or changes in land quality are influenced by economic, environmental, and institutional factors, and • whether land degradation over time threatens productivity growth and food security at local, regional, and global levels.
