- Agricultural mindsets across social networks in four African countriesMoore, Keith M.; Fornito, M.; Gunter, J.; Lamb, Jennifer; Sikuku, Dominic Ngosia; Shibonji, D.; Bashaasha, Bernard; Marake, Makoala V.; Keita, Moussa; Lambert, Dayton M.; Norton, James B. (2014)This PowerPoint presents research examining agricultural mindsets and social networks in Kenya, Uganda, Lesotho, and Mali. It identifies three agricultural mindsets exist which characterize farmer goals, values, and identities. These are: conventional agriculture (market-oriented production involving mechanical implements, agrochemical use and mono-cropping), risk-averse agriculture (livelihood diversification, distribution of risk, avoidance of market dependence), and conservation agriculture (minimal tillage, maintaining a soil cover and crop rotations). Mindsets of farmers and non-farm agents are explored through survey data. Relationships between actors, and mindsets of key actors are displayed in maps of social networks in Kenya and Uganda. The presentation concludes by emphasizing that agro-ecological, socio-cultural, and historical context matters, and calls for the development of an innovation system that is catalyzed by innovation brokers.
- Analysis of productivity and soil carbon in response to time-controlled rotational grazing in the West African Sahel regionBadini, Oumar; Stöckle, C. O.; Jones, J. W.; Nelson, R.; Keita, Moussa (2005)Preliminary data from Mali indicate that soil carbon levels are higher under pastures than croplands. Rotational grazing allowing biomass growth during periods (days or weeks) with no livestock grazing could result in more root and aboveground mass residues added to the soil. It is therefore hypothesized that rotational grazing will increase both soil carbon and pasture biomass production. A rotational grazing area (150 ga) was established in Torokoro, Mali (West Africa) to test this hypothesis. Because it could take many years to experimentally evaluate whether soil carbon levels are indeed increasing, a simulation-based sensitivity analysis was performed to evaluate potential changes in production and soil carbon and to assess critical factors that might affect the performance of this management practice. A cropping systems model, CropSyst, was used to conduct this analysis. For this purpose, an improve soil carbon and a new rotational grazing submodel were incorporated in the model.
- Analyzing changes in productivity and carrying capacity under planned grazing in Madiama Commune, Mali (West Africa)Badini, Oumar; Stöckle, C. O.; Jones, J.; Bostick, M.; Kodio, Amadou; Keita, Moussa (2004)This presentation addresses the problems of overgrazing and degradation of pasture land. Policies that can increase pasture productivity and improve the carrying capacity and soil quality of pastures are assessed using CropSyst simulation modeling. Optimal grazing intensity and intervals (rotational grazing) are evaluated and discussed, based on model analysis from the Madiama commune in Mali (West Africa).
- Controlled grazing: Botanical response and animal performanceAbaye, Azenegashe Ozzie; El Hadj, Meriam; Kodio, Amadou; Keita, Moussa (Wallingford, Oxon; Cambridge, Mass.: CABI Publishing, 2005)In chapter 15, Abaye et al. investigated the regenerative potential of pastureland in two villages through a controlled experiment with tethered grazing of small ruminants. This work builds on the Holistic Management (chapter 9) insight that animal impact is not simply a function of numbers of livestock or duration of grazing time in order to provide management indicators that optimize the potential of forage regeneration/biomass production rates, plant biodiversity, and animal performance. The chapter concludes that grazing vegetation down to a 3cm height on any particular parcel is likely to limit forage regeneration.
- Dry season feed supplements: The potential role of Cassia toraEl Hadj, Meriam; Abaye, Kodio; Kodio, Amadou; Keita, Moussa (Wallingford, Oxon; Cambridge, Mass.: CABI Publishing, 2005)In chapter 14, El Hadj et al. describe research in response to a request by Peul village women to deal with Cassia tora, an invasive plant that is unpalatable for grazing animals. As pasture lands have degraded, Cassia tora has spread throughout their fields out competing other plants. However, this noxious plant has potential as dry season forage when ensiled. The authors describe their analysis of the forage potential and their work with village women to develop ensilage techniques adapted to local conditions.

- Gender differences in agricultural production strategies: Variations by village and social networkFornito, M.; Moore, Keith M.; Keita, Moussa; Van Houweling, Emily (2014)This presentation identifies relationships between farm men, farm women, and non-farm agents and their respective agricultural mindsets using social network analysis and factor analysis.
- Qualité de l'ensilage, caractéristiques chimiques, et palatabilité de la Cassia tora ensilé contre fraisEl Hadj, Meriam; Abaye, Kodio; Keita, Moussa (2004)Cassia tora (Foetid cassia) is the most prevalent weed species in the West African region of Mali. In most parts of Mali, the lack of pasture and forage resources has been a growing problem. C. tora is considered as a poisonous plant. However, the toxic element in C. tora has not been clearly defined. The objectives of our experiment are: to evaluate the chemical characteristics of ensiled vs. fresh C. tora; to investigate the effect of additives on the quality of the ensiled material; to provide feed for the dry season and to examine the effect of the ensiling processes on the toxic chemical (or chemicals) present in the fresh C. tora.
- A simulation-based analysis of productivity and soil carbon in response to time-controlled rotational grazing in the West African Sahel regionBadini, Oumar; Stöckle, C. O.; Jones, J. W.; Nelson, R.; Kodio, Amadou; Keita, Moussa (Elsevier Ltd., 2007)In the Sahel region of West Africa, the traditional organization of the population and the grazing land avoided overexploitation of pastures. Since independence in the 1960s, grazing lands have been opened to all without specific guidance, and the vulnerability of the pastures to degradation has increased. Rotational grazing is postulated as a possible solution to provide higher pasture productivity, higher animal loads per unit land, and perhaps improved soil carbon storage. The objective of this study was to conduct a simulation-based assessment of the impact of rotational grazing management on pasture biomass production, grazing efficiency, animal grazing requirement satisfaction, and soil carbon storage in the Madiama Commune, Mali. The results showed that grazing intensity is the primary factor influencing the productivity of annual pastures and their capacity to provide for animal grazing requirements. Rotating the animals in paddocks is a positive practice for pasture protection that showed advantage as the grazing pressure increased. Increasing the size of the reserve biomass not available for grazing, which triggers the decision of taking the animals off the field, provided better pasture protection but reduced animal grazing requirements satisfaction. In terms of soil carbon storage, all management scenarios led to reduction of soil carbon at the end of the 50-year simulation periods, ranging between 4% and 5% of the initial storage. The differences in reduction as a function of grazing intensity were of no practical significance in these soils with very low organic matter content, mostly resistant to decomposition.
