Focus on... Rehabilitating degraded land
Across vast areas of the world, human activity has degraded once fertile and productive land. Deforestation, overgrazing, continuous farming and poor irrigation practices have affected almost 2 billion hectares worldwide, threatening the health and livelihoods of over one billion people.
As fertile soil is degraded, those who rely on the land are less able to grow or harvest sufficient food, and their hopes of improving their livelihoods are diminished. In this edition of New Agriculturist, we focus on some of the approaches and policies that can help to successfully rehabilitate degraded land. While each of the articles highlights different approaches, the common theme for successful restoration of farmland is the importance of involving local communities and the need to change existing agricultural practice.
