The United Nations' Food and Agriculture Organization (FAO) and Refugee Agency (UNHCR) launched a new handbook to help restore forests in displacement-affected areas, where heavy reliance on woodfuel puts forests and woodlands in jeopardy. An estimated 2.4 billion people - about a quarter of the global population - depend on wood as their main energy source for cooking. In areas hosting displaced populations, often with scant resources of their own, dependence on woodfuel is even more dramatic. More than four out of five forcibly displaced people worldwide use woodfuel for cooking and heating. This is the main driver of forest degradation and deforestation in these areas.
