Attenuation of the effects of desertification through sustainable development of Great Green Wall in the Sahel of Africa

Purpose - The purpose of this paper is to develop the Great Green Wall (GGW) Project initially financed by the United Nation's Global Environment Facility Trust Fund, is a Pan African proposal in greening the Sahel of Africa from West (Dakar) to the East (Djibouti). It aims at reducing poverty and soil degradation in this region, taking into account the effects of desertification and climate change on sustainability of livelihoods. Design/methodology/approach - Several desertification attenuation projects in Nigeria are employing different methods for maximum benefits obtainable from the objectives of the particular projects. As noted above, however, the approach of GGW is to improve the alternative livelihoods of the people by their active participating in the implementation of the project. It is also noted that environmental impact assessment, community reconnaissance or needs assessments might be initial part of pre-project activities, thereby making the communities more aware and educated of the impending environmental problems. Findings - Desertification has reached an alarming state in Nigeria. The frontline desert threatened States of Nigeria constitute 43 percent of the land mass of the country. With increased pressure of desertification, exacerbated by a period of prolonged drought of more than 20 years, climate change and human activities, it is becoming increasingly difficult to obtain sustainability in the management of the fragile lands and the region's ecosystem. Strategic interventions in combating the problem of desertification in Nigeria have attenuated some of the detrimental social, economic and environmental impacts on the affected communities. Programmes and projects have strengthened the resilience of the people, participating in sand dune stabilization, the Great Green Wall Sahara Sahel Initiative, including shelterbelt developments. Government has sustained inputs in environmentally friendly agriculture and also encouraged synergetic collaborative activities with international and national NGOs, international agencies and local institutions. Originality/value - These results/activities give evidence of the increased public awareness of environmental degradation due to desertification and climate change in Nigeria; the realization in environmental stabilization needs with ready participation of the communities for improved livelihoods in environmental activities and arid agriculture as supported by the National Great Green Wall (NAGGW) program of the country; resulting in internalization of these projects supporting livelihoods for sustainability in the Sahel of Nigeria.
