This chapter sets out to present a short review of (i) the general context of land degradation under the framework of UNCCD – the international convention on desertification with a specific focus on Land Degradation Neutrality, and (ii) examples of the main processes responsible for soil degradation (e.g. surface crusting, runoff and water erosion, tillage erosion, wind erosion, and salinization), along with the principles of desertification control and land rehabilitation, in light of the socioeconomic context and ecological conditions and processes.

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.

Global food production must ramp up in the face of enormous challenges. We are all familiar with many of the key metrics surrounding the central food security challenge: By the year 2050, the earth’s population is expected to soar from the current 7bn about 9.6bn. 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.
