States of ecological maturity and temporal trends of drylands in Morocco, Algeria and Tunisia north of 28 N are reported for 1998–2008. The input data were Normalized Difference Vegetation Index databases and corresponding climate fields, at a spatial resolution of 1 km and a temporal resolution of one month. States convey opposing dynamics of human exploitation and ecological succession. They were identified synchronically for the full period by comparing each location to all other locations in the study area under equivalent aridity.

Becoming land degradation neutral is not simply about restoring degraded lands. It is about self interest making sure the land can still provide food and fresh water for us, our children, and to the third and fourth generations. It is about giving every child, from Mongolia to Afghanistan and from Ethiopia to China, the fighting chance for a better life. If this all sounds too good to be true, read this book.

It is estimated that in the next 40 to 50 years, we will need to produce as much food as was necessary in the previous 10,000.
