The Haitian people are facing serious problems of environmental degradation that threaten the economic livelihoods of many resource-poor farmers. Structures to retard the process of soil loss have been adopted reluctantly and, even when adopted, the management and maintenance have been less than desirable. We evaluate the factors that influence the adoption and management of alley cropping in Haiti. Results of the adoption model show that institutional factors, such as membership in a local peasant organization and training in soil conservation practices, favorably influence adoption. Socio-economic factors such as gender, per capita income, and interaction between education and per capita income also significantly influence adoption of alley cropping in Gaita and Bannate. The management of alley cropping is influenced by demographic, socio-economic, institutional, and physical factors. The relative importance of each factor on the probability of adoption and management of alley cropping varies from one variable to another. The study generates important information for resource allocation in the establishment of alley cropping as a soil conservation structure.
海地人民正面临严重的环境退化问题，这威胁着许多资源匮乏农民的经济生计。减缓土壤流失进程的措施是在不情愿的情况下采用的，即便采用了，管理和维护情况也不尽如人意。我们评估了影响海地采用和管理间作套种的因素。采用模型的结果表明，诸如加入当地农民组织以及接受土壤保护措施培训等制度因素，对采用间作套种有积极影响。诸如性别、人均收入以及教育与人均收入之间的相互作用等社会经济因素，在盖塔和班纳特地区对采用间作套种也有显著影响。间作套种的管理受到人口、社会经济、制度和自然因素的影响。每个因素对采用和管理间作套种可能性的相对重要性因变量而异。该研究为将间作套种作为一种土壤保护结构来建立时的资源分配提供了重要信息。
