An environmental geographical study on the moral economy of rural societies in Kenya's semi-arid areas

本研究探讨了肯尼亚中部定居农村社会的社会经济方面和可持续的环境利用，该地区经历了快速的人口增长和土地向半干旱地区的扩张。1.选择莱基皮亚平原Ewaso Ngiro支流沿着的灌溉方案，研究确定了社会经济分层与农民灌溉收益分配之间的正相关关系，调查移民过程与土地利用变化、土地权属与灌溉方式、旱季灌溉现状。然而，当许多生产者采取小规模生产的风险最小化战略时，这种关系不一定是积极的，如在出口园艺的合同种植中，生产者的价格和利润受到全球和季节性条件以及劳动力成本最小化的影响。研究还指出，强调家庭自主的道德观在个人化的社会环境下被泛化了， ...更多信息 艾德使用的水，土地和劳动力，这阻碍了灌溉系统的社区管理。2.研究的地貌部分检查在两个地区在不同的气候条件下，在Ewaso Ngiro的最高流域发生的斜坡过程的详细信息。位于亚热带高原地区的阿伯代尔山，谷坡滑坡和多处滑塌频繁发生，群众运动较快。另一方面，在半干旱的莱基皮亚平原，大部分坡面上广泛出现了片流水，这导致了近年来局部强烈的片蚀。研究结果表明，半干旱地区的地形变化主要取决于土地利用方式的变化。3.本研究将上述灌溉方案中的营销策略作为肯尼亚经济后结构调整时期区域联系的案例，以更好地了解该方案所处的环境。少

This study examines socio-economic aspects and sustainable environmental use in the sedentary rural society in Central Kenya, which has experienced rapid population growth and field expansion into semi-arid areas.1.Selecting an irrigation scheme along a tributary of Ewaso Ngiro in the Laikipia Plain, the study identifies a positive relationship between socio-economic stratification and irrigation-benefit distribution among the peasants, investigating the settlement process and land use change, ownership of land and irrigation means, and the reality of dry-season irrigation. However, the relationship is not necessarily positive when many producers adopt the risk-minimizing strategy of small-scale production as is found in the contract farming of horticulture for export, where the producer price and profit are subject to global and seasonal conditions and labor cost minimization. The study then points out that the moral stressing household autonomy has been generalized under individualiz … More ed usage of water, land and labor, and that this has hampered communal management of the irrigation system.2.The geomorphological part of the study examines detailed information on slope processes occurring in two areas under different climatic conditions, in the uppermost drainage area of Ewaso Ngiro. In the Aberdare Mountain, situated in highland sub-tropical areas, many landslides and multiple slumps frequently take place on the valley-side slopes, and it has undergone relatively rapid mass movements. On the other, in the semi-arid Laikipia Plain, sheetwash extensively appears on the most slopes, which locally results in intensive sheet erosion of recent years. It is concluded that considerable landform changes due to sheetwash can occur in semi-arid areas, depending on land use change.3.The study illuminates marketing strategies in the above irrigation scheme as cases of regional linkages in the era of post structural adjustment of the Kenyan economy to understand better the situation where the case scheme was located.
