在雨水灌溉条件下种植农作物是肯尼亚中北部前游牧民族Pokot最近的一项创新。我们从跨学科的角度研究了土地利用变化的社会生态动态。向农牧业过渡的模式与该地区的生态物理属性和家庭的经济特点密切相关。虽然在高地采用先进的农艺措施可使玉米年产量达到20亿公顷以上，但不利的气候和土壤条件，以及低地和中山地带新农民的农艺知识有限，使那里的大田作物生产成为一种机会主义的、空间分散的和相当不稳定的土地利用战略。向作物种植的加速过渡以及各区定居化的时空差异，导致土地支离破碎和短缺，从而导致家庭间的不平等加剧，Pokot社会内部的冲突增加。
Crop cultivation under rain-fed conditions is a recent innovation among the formerly pastoral-nomadic Pokot in north-central Kenya. We have examined the socioecological dynamics of land-use change from an interdisciplinary perspective. The patterns of transition to agropastoralism are closely related to both the biogeophysical attributes of the area and the economic characteristics of the households. While the use of advanced agronomic practices in the highlands is associated with annual maize grain yields of >2Mg ha(-1), unfavorable climatic and edaphic conditions, as well as the limited agronomic knowledge of the newcomer farmers in the lowland and mid-hill zones, make field crop production there an opportunistic, spatially scattered, and rather erratic land-use strategy. The accelerated transition to crop cultivation and the spatiotemporal differences in sedentarization between zones contribute to a fragmentation and shortage of land, which results in growing interhousehold inequalities and increasing conflicts within Pokot society.
