摘要

Land degradation is a global problem negatively affecting sustainable development and human well-being, and it can be affected by action taken on a very local scale. It is also a tricky problem because it is dynamic, driven by both biophysical and socioeconomic factors simultaneously. The global human appropriation of net primary production (HANPP) doubled in the 20th century, driven by 4-fold and 17-fold human population growth and economic output increase. A conservative projection indicated that there will be a further 18% increase of HANPP from the 2000s to the 2040s.2 Therefore, the land degradation problem could be more widespread and difficult to tackle as the human population grows and its natural resources use increases pressure, along with the demand for better human welfare. Therefore, land degradation control has been made one of the priorities for action, from farmer household to international levels (e.g., Food and Agricultural Organization and United Nations Convention to Combat Desertification), promoting sustainable land management across all levels. However, we argue that the science for land degradation is premature with insightful conceptual development but mismatched and unbalanced support from practical research, which need to be addressed for a more fruitful land degradation research.
