  • An economic evaluation of alternative soil management technologies
    Wyeth, P.; Traoré, Boureima; Badini, Oumar; Sidi, M.; Touré, M.; Brewster, Carlyle C. (Wallingford, Oxon; Cambridge, Mass.: CABI Publishing, 2005)
    In chapter 12, Wyeth et al. pursue the issue of sustainability of technologies for enhancing soil fertility from economic and financial perspectives. This analysis takes into account the results of three years of on-farm trials and combines those findings with the output of the computer modeling analyses of Badini et al. (chapter 11). Their results suggest that corralling livestock in the fields, spreading manure and micro-dosing with chemical fertilizer are adoptable within the range of farmers' risk preferences.
  • Economic interdependence among socio-economic groups in Madiama Commune of the Niger Delta of Mali
    Kaboré, D.; Brewster, Carlyle C.; Bertelsen, Michael; Wyeth, P. (2001)
    One aim of the SANREM West Africa Project is to identify the linkages among socio-economic groups in the Madiama commune of northern Mali. The results from compiling a Social Accounting Matrix (SAM) were reported earlier. These results clearly demonstrated that transhumants are the least favored of the occupational groups, so that any development interventions should address this group separately. In this paper, the SAM is disaggregated further and decomposed multipliers computed. Three groups of decomposed multipliers are computed - direct effect, open loop and closed loop multipliers. The process of decomposition separates the impact of interactions among production activities from that due to interactions among socio-economic groups. These latter interdependencies are important to understand in a commune where rivalry among groups for resources is strong. Analysis of the multipliers and the pattern of primary commodity sales and microenterprise activity reinforces earlier conclusions about the importance of the livestock sub-sectors and the fragile position of the transhumant pastoralists.
  • Economic linkages among occupational groups in the commune of Madiama
    Brewster, Carlyle C.; Kaboré, D.; Bertelsen, Michael; Wyeth, P. (Wallingford, Oxon; Cambridge, Mass.: CABI Publishing, 2005)
    In chapter 13, Brewster et al. model the economic linkages between different groups of natural resource users and analyze the effect of the potential growth strategies. Using data from the PLLA (chapter 6) and an extensive household and enterprise level data set, a Social Accounting Matrix (SAM) model for the Commune of Madiama was developed. Application of this model demonstrated that the largest impacts from exogenous changes in demand are associated with rice and livestock sectors. Furthermore, impacts are shared differentially among socioeconomic groups with agropastoralists benefiting most and the transhumant group benefiting least.

    Natural resource management institution building in the decentralizing context of West Africa: the SANREM CRSP approach
    Moore, Keith M.; Bertelsen, Michael; Diarra, L.; Kodio, Amadou; Cissé, Salmana; Wyeth, P. (Blacksburg, Va.: SANREM CRSP WA, 1999)
    A far-reaching restructuring is beginning to take place in West Africa. There is general recognition in the region that central governments are poorly placed to make many decisions appropriate for local levels. Particularly in areas of agriculture and natural resource management (NRM), local populations are being asked to take leadership in deciding appropriate land uses and ownership/usufruct of resources. The continuing and accelerating degradation of the natural resource base and changes in the socioeconomic environment of the region has added urgency to decentralization strategies. However, the current policy of decentralization across West Africa has become largely a matter of deconcentration. Although village-level (terroir) management has demonstrated significant success in community-based NRM, authority and resources resulting from decentralization laws do not reach this level. This paper describes the SANREM CRSP s attempt to organize and support a provincial-level NRM advisory board and orient technical interventions by providing training in Holistic Management.
  • The Sciences and Art of Adaptive Management: Innovating for Sustainable Agriculture and Natural Resource Management
    Moore, K. M. (ed.) (Ankeny, IA: Soil and Water Conservation Society, 2009)
    In this book, various authors describe their expertise and each explains a different aspect of adaptive management. This collective work offers a detailed breakdown of the nested landscape system, related case studies, and successful solutions for land management practices.
  • Sustainable agriculture and natural resource management in farm enterprise systems
    Wyeth, P. (Ankeny, IA: Soil and Water Conservation Society, 2009)
    This chapter describes the farm enterprise system. The farm enterprise system involves the consumption, sales, and investment of farm resources, but recognizes the economic, institutional, and cultural environment external to farms still have a large effect on the ability and motivation of farmers to efficiently use resources and use sustainable land management practices. Influences such as family demands, assessment of risk, educational opportunities, innovation, clear land and water rights, and social and religious norms can greatly impact the management decisions and practices of farmers.
