Towards land degradation neutrality Maintaining or improving the condition of our land resources by securing healthy and productive land will dramatically reduce poverty, ensure food and water security and improve the living conditions of countless people around the world. Our future depends on the land and its resources. The sustainable management of our soil, water and biodiversity can help realize their economic, social and environmental benefits. LDN also includes the restoration of degraded natural ecosystems that provide vital services to people and working landscapes.”(Source: www.UNCCD.int ) The World Overview of Conservation Approaches and Technologies (WOCAT ) promotes sustainable land management (SLM) and shares their knowledge. Their network of specialists facilitates the reporting, the dissemination and the implementation of locally adapted SLM practices. WOCAT defines 4 categories of measures to prevent, mitigate and rehabilitate land degradation and restore ecosystem services. Agronomic measures improve the soil (mulching, manuring, conservation tillage). Vegetative measures consist in planting trees, shrubs or grasses. Structural measures change the structure of the land (terraces, dams, ditches). Management measures include change of land use, intensity, timing. Combinations of measures are possible. WOCAT, 2011 The Great Green Wall of Africa’s objective is to improve the resilience of human and natural systems in Sahel and Saharan areas faced with climate change through healthy ecosystem management and sustainable development of natural resources (water, soil, vegetation, fauna, flora), protection of tangible and intangible rural heritage, the development of rural production and sustainable development Pierre GRARD - CIRA
