ABSTRACT Contingent valuation is used to elicit irrigators’ willingness to pay for soil moisture tools in irrigation schemes in Africa, with various econometric methods employed to mitigate potential bias. Key results include that there is a neighbourhood effect influencing adoption, and that being located downstream and spending more on irrigation water positively and statistically significantly influenced willingness to pay for tools. The result suggests that although focusing on economic incentives and promoting farmer learning by those using the tools may promote greater adoption, there is likely to still be a need for co-investment by other bodies.

灌溉者愿意为东南非采用土壤水分监测工具支付费用

摘要 在非洲的灌溉计划中，使用条件评估来激发灌溉者为土壤水分工具付费的意愿，并采用了各种计量经济学方法来减轻潜在的偏差。主要结果包括存在影响采用的邻里效应，以及位于下游并在灌溉用水上花费更多的积极和统计显着影响支付工具的意愿。结果表明，尽管关注经济激励措施并促进使用这些工具的农民学习可能会促进更多采用，但可能仍然需要其他机构的共同投资。
