    CLIMATE CHANGE ADAPTATION IN AFRICA: ITS IMPLICATIONS AND SOCIO-ECONOMIC PROSPECTS FOR FARMERS IN THE SUB-SAHELIAN AGRO-ECOLOGICAL ZONE OF NIGERIA
    (Department of Geography, Nasarawa State University Keffi, 2007-10-01) Ayuba, H.K.
    Climate change is a phenomenon whose effects and impacts would affect peoples and nations differently. Nigeria and its people are expected to be most affected by the impacts of climate change, through sea level rise along its coastline, intensified desertification,erosion, flood disasters, and general land degradation. Northern Nigeria is one of the most threatened land areas to climate change in the country. The region lies largely within the semi-arid zone, which is recognized as a dynamic ecosystem as a result of highly variable and unpredictable rainfall, seasonal fires, high temperatures, overgrazing and other anthropogenic influences. In addition, poverty, increasing population growth and the poor resource endowment makes it difficult to find solutions to these problems without comprehensive policy changes and public enlightenment. Some of these environmental problems are highly interactive and interlinked with health, water supply, nutrition, poverty, unemployment, and poor agricultural productivity. The resulting decline in agricultural productivity from increased droughts and desertification will further raise the vulnerability of the region to climate change.

    DESERTIFICATION AND SUSTAINABLE UTILISATION OF NATURAL FOREST RESOURCES IN BORNO STATE
    (Department of Geography, Nasarawa State University Keffi, 2002-03-12) Ayuba, H.K.; Daura, M.M.; Ijere, J.A.; Maryah, U.M.; Msheliza, Deborah S.
    The United Nations Convention to Combat Desertification (UNCCD) defines desertification as:"land degradation in arid, semi-arid, and dry subhumid areas resulting from various factors, including climatic variations and human activities (United Nations, 1994). Furthermore, UNCCD defines land degradation as a: "reduction or loss, in arid, semi-arid, and dry subhumid areas, of the biological or economic productivity and complexity of rain fed cropland, irrigated cropland, or range, pasture, forest and woodlands resulting from land uses or from a process or combination of processes, arising from human activities and habitation patterns, such as soil erosion, deterioration of the physical, chemical, and biological or economic properties of soil; and long-term loss of natural vegetation" (United Nations,1994). Desertification, if not controlled, could convert an erstwhile fertile and productive land into an infertile and unproductive one, with devastating socio-economic and political consequences for both the local and international communities.

    TOWARDS PROMOTING COMMUNITY-BASED FOREST MANAGEMENT IN THE SUDAN/SAHEL ECOLOGICAL ZONE OF NIGERIA
    (Department of Geography, Nasarawa State University Keffi, 2007-03-01) Ayuba, H.K.
    Past forest policies and legislation in Nigeria have neglected the role of communities in the development of community forestry. This has led to forest degradation in most of the forest reserves as local people illegally exploit forest products and engage in farming in and around the forest reserves. However, in recent years, community-based forest management (CBFM) has emerged as one of the major responses to the problems caused by widespread loss of frees and forest cover. Its aim is to help local people solve their own fuelwood supply problems, meet their own non-timber forest products ’ needs, and preserve the environment in which they live.
