“…Process-based models are potentially much more reliable; however, they are still in the design phase, and will need several years of further development before they can be used under developing country conditions-see, for instance the WEPP (Foster and Lane 1987) model, and the models developed by Morgan et al (1986), Kirkby and Neale (1985), De Ploey (1990) and others. Once developed, their application will not be free of significant levels of uncertainty.…”

This paper critically reviews the three main approaches to land degradation and conservation-the classic, populist and neo-liberal. The implications of these paradigm shifts are examined in terms of research needs. Next, the paper discusses the role of science and technology, and the origins and substance of differences in the perception, evaluation and diagnosis of degradation. Focus is then shifted to analyzing how farmers and pastoralists make decisions about resource use and management, and a research approach is suggested for analyzing decision-making. Two case studies illustrate the approach. ix 4 Chapter I-Changing Paradigms in Land Degradation Research identification of the problem as serious, indicating that soil conservation and land reclamation are urgently needed; technical measures requiring the cooperation of the community are recommended; and plans are implemented through a combination of encouragement, persuasion, and subtle threats sometimes backed by more coercive powers. Key points are the lack of any account of the position of the participants (the natural resource users themselves), and the reliance on experts. The typical response to failures with this approach has been to find "escape hatches" (Clay and Schaffer 1984), blaming unfavorable weather, lack of cooperation by different government departments, lack of political will, or lazy and uncooperative farmers. However, the view from another paradigm instead sees classic soil conservation intervention failure in terms of five major problems:

“…Complementary studies are being carried out (Foster, 1990), especially in Europe, for both temperate environments (Boiffin and Monnier, 1986;de Ploey, 1989; Le Bissonnais, 1990;de Roo, 1991) and Mediterranean environments (Morgan et al, 1986;Morgan, 1990;Rubio and Rickson, 1990;Albaladejo et al, 1991).…”

An assessment of the spatial and temporal variability of certain factors that condition the susceptibility of soils to erosion, i.e. surface states of bare ground, vegetation and morphology is possible through remote sensing. This approach is greatly helped by the precise management and flexibility in the use of GIS systems. These assets should further the acceptance of remote sensing in the spatial modeling of hydraulic runoff and erosion.
