如果水产养殖业为穷人提供初级生产者以外的机会，那么它就有相当大的潜力为减贫作出贡献。将水产养殖纳入减贫方案提供了使生产系统多样化和减少粮食不安全的手段，但也需要改善水产养殖可以为贫困农户提供更可持续生计的地方的市场。本研究回顾了柬埔寨贫困人口目前在进入市场方面面临的限制，并分析了其对贫困人口国内水产养殖业发展的影响。我们使用基于地理信息系统的空间贝叶斯概率模型来模拟市场准入，并估计在四种不同情景下可能从市场准入改善中受益的贫困人口数量。对二级数据的分析表明，贫穷的水产养殖生产者与柬埔寨城市市场互动的潜力目前很低。然而，水产养殖与农村市场互动的潜力很大。结论是，通过改善贫困生产者和消费者进入柬埔寨农村市场的机会，水产养殖业的发展有相当大的潜力降低国内进出口贸易的交易成本。改善农村市场准入的水产养殖发展战略可能包括惠及多达100万贫困的水产资源使用者。
Aquaculture holds considerable potential to contribute to poverty alleviation, if it provides poor people with opportunities other than as primary producers. Integration of aquaculture into poverty reduction programmes provides means to diversify production systems and reduce food insecurity but also needs improved markets in locations where aquaculture can oier sustainable livelihoods to poor farming households. This study reviews the current constraints that poor people face in accessing markets in Cambodia and analyses its implications for propoor domestic aquaculture development. We use a Geographic Information System-based spatial Bayesian probability model to simulate market accessibility and estimate the numbers of poor people who could potentially bene¢t from improved market access under four diierent scenarios. Analysis of secondary data con¢rms that the potential for poor aquaculture producers to interact with urban markets in Cambodia is currently low. The potential of aquaculture to interact with rural markets is, however, high. It is concluded that the development of aquaculture has considerable potential to reduce the transaction costs in domestic ¢sh trade by improved access of poor producers and consumers to rural markets in Cambodia. An aquaculture development strategy that improves rural market access could include bene¢ts for up to 1 million poor aquatic resource users.
