Agricultural policies need to shift from a focus on "land productivity" to "water productivity", writes Theib Oweis, of the Syria-based International Center for Agricultural Research in the Dry Areas (ICARDA), in a compilation of abstracts of new research presented at a conference organised by the centre.
The book provides a valuable snapshot of research that is probing the impact of climate change in countries like Qatar, Jordan, Nigeria, Kenya, Sudan and Syria, and trying to develop coping strategies along the way.
Almost 95 percent of Qatar is desert, making the entire country a dry area. Dry areas can be found in almost any country and they all come with a peculiar set of problems - rapid population growth, chronic poverty, land degradation - which make the people living in them even more vulnerable.
Besides country-specific research, the compilation has little gems on how weed will thrive in higher levels of carbon dioxide, and how a fungus could help prevent erosion. The world's arid areas have probably not had the coverage they need, but this book goes some way to filling the gap.
