Arid ecosystem covers one third of the Earth's surface and is the home town of majority of the population of the world. This ecosystem is also important because it has significant roles in land and water resources management. However, due to anthropogenic land use activities or shifting climate conditions, the features of the ecosystem change and cause diminished vegetative cover, reduced productivity, increased soil erosion, invasion of exotics, and loss of native species. Moreover, in the recent years, earth's vegetative cover may exceed the ecosystem's capacity to adapt, which happens through the consequence of rapid land degradation along with desertification. Therefore, this chapter provides how different regions endeavor with this arid ecosystem by performing various adaptation practices.

Burkina Faso is a land-locked country, sharing a border with six other countries, namely Mali, Niger, Benin, Togo, Ghana, and Cote D'Ivoire in the zone of West Africa (Fig. 1). Due to the geographical location of the Sahel region, the country's climate is characterized by rainy and dry seasons. According to the Human Development Report in 2010, the country has a very weak economy with a GDP of 522 USD per habitant, principally based on agriculture (25%), animal production (12%), and forestry/fishery (3%) (MECV & SP/CONEDD, 2006a). The population growth is extremely high at 2.8%, with 46.4% of the population living below the national poverty line and 81.2% living on less than $2 a day (UNDP, 2009). The biomass energy is the largest primary energy source covering 80% of total consumption, thus accelerating soil degradation as well as deforestation.
