This paper examines the evidence for land degradation in Burkina Faso, and argues that local farming practices are not as unsustainable and environmentally destructive as many reports suggest.Main findings of the study include:there is little evidence of widespread degradation of crop and fallow land in Burkina Faso; the low external input practices used by West African farmers are not leading to region wide land degradation processesa major reason for the overestimation of land degradation has been the underestimation of the abilities of local farmersthere is much more to soil and water co

An agricultural watershed, situated on an island of the Aegean archipelago, was studied in order to gain insight into the structure and the design of a typical terrestrial ecosystem of the Mediterranean region. Fieldwork was focused on the comparative study of seasonal patterns of inorganic nutrients, organic nitrogen, and erosion over the most abundant vegetation types of the area, such as olive groves, maquis, and wetlands. Nutrient losses via the pathway of erosion were provided by the determination of nutrient concentrations in runoff sediments.

The development of agricultural technologies and a better appreciation of the existing but under-utilised knowledge of resource management will be crucial in meeting the ecological needs and in achieving the anticipated food demands of the growing population in the future. The greatest challenge for the coming decades lies in the fact that the production environments are unstable and degrading. Land degradation is proceeding so fast that unless policies and approaches change, many countries will not be able to achieve sustainable agriculture in the foreseeable future.

Examines the contrast between the formulation of problems in development policy, and the perspectives of villagers in Kissidougou (Guinea) in relationship to 'demonstrably' false ideas about environmental change.

About two-thirds of Africans depend on agriculture for their livelihoods. The fate of agricultural production, therefore, directly affects economic growth, social improvement, and trade in Africa. As the region's population continues to grow rapidly, outpacing the growth rate in other regions of the world, its agriculturalland is becoming increasingly degraded. Farmers are intensifying land use to meet food needs without proper management practices and external inputs.

Low agricultural productivity, land degradation and poverty are severe interrelated problems in the East African highlands. While the proximate causes of such problems are relatively well known, the underlying causes are many and complex, and depend upon many site-specific factors that vary greatly across the diverse circumstances of the region. In this paper, we argue that the appropriate strategy for sustainable development depends greatly upon the “pathways of development” that are feasible in a given location.

La dégradation des ressources naturelles est devenue un problème mondial qui menace les moyens d’existence de millions de pauvres. De nombreuses technologies très prometteuses sont actuellement disponibles, notamment en matière de gestion des ressources naturelles, mais les exploitants agricoles et les autres intervenants hésitent souvent à les employer. Pourquoi? Bien que de nombreux facteurs puissent l’expliquer, l’absence de droits de propriété garantis et l’insuffisance d’actions collectives devrait retenir l’attention des décideurs et des développeurs
de technologie.

"Degradation of natural resources has become a global problem that threatens the livelihood of millions of poor people. Many promising technologies for natural resource management are available to address these problems, but farmers and others often fail to adopt them. Why is this? Although many factors can be identified, lack of secure property rights and collective action deserve greater attention from policy makers and technology developers.

Australia's 'Landcare' program is a community-based participatory program established by government to tackle the problem of land degradation. Landcare involves thousands of Australians working together in locally based groups, tackling problems of common concern. Government and community are now looking to 'scale up' the Landcare idea to a regional level. State and territory governments have moved to create regional (often watershed-based) frameworks for land management planning and resource conservation, in accordance with the concept of integrated watershed management.

Agroforestry can help prevent land degradation while allowing continuing use of land to produce crops and livestock. A problem with the evaluation of agroforestry using long-run static models and traditional discounting techniques is that the present value of the forestry enterprise is generally much lower than that of other production activities. This problem is common with Australian native species which tend to have a high environmental value but a low market value.
