Introduction 1.1 Background The sustainable use of natural resources has emerged as big issue in the contemporary world. The importance of sustainable use of natural resources has increased because of its relationship with world food security and healthy environment. These days the water and land ecosystems are being degraded at an alarming rate (Hannam, 2003 cited in Teketel, 2009). Natural resources, agriculture and human activities are interrelated in developing countries. The human population uses these natural resources for their livelihoods. Some of the resources include forests for fuel wood and construction material, soil and water for agricultural activities, and minerals for different purposes. Natural resources are over…show more content…
The land degradation affects agricultural productivity. The food security is fundamentally influenced by economic, environmental and institutional factors (Hurni et al. 2010). Interactions between the two systems are caused by two interlocking complex systems. The natural ecosystem and the human social system determine the success or failure of resource management (Berry 2003). Principal processes of land degradation include clear cutting and deforestation, depletion of soil nutrients through poor farming system, over grazing, and inappropriate irrigation. It is a continuous process and has become, however, an important concern affecting food security and the wealth of nations. Ethiopia is endowed by the presence of diverse fauna and flora resources. However, natural resource degradation in Ethiopia has been going on for centuries (Hurni et al. 2010). Similarly, Berry (2003) also stated that land degradation frequently occurs under rapid population growth. Not only the number of people, but also the lifestyle and consumption pattern affect the environment. Over utilization, mismanagement of natural resources, and production of wastes lead to loss of biodiversity, air and water pollution, and increased human and animal population pressure on arable land. Current population of Ethiopia is about 90 million with a 2.16% population growth rate. Rapid population growth, limited arable land, and a shortage of employment opportunities in the industrial and
