We evaluated the local impacts of World Bank development projects on sites of recognized conservation significance (Important Bird and Biodiversity Areas [IBAs]) using tree cover change data and in situ state, pressure, and response monitoring data. IBAs adjacent to World Bank project locations and a matched set of IBAs distant from World Bank project locations had similar rates of tree loss and similar in situ measurements of conservation outcomes. Thus, we did not detect any significant net negative impacts of World Bank projects on tree cover or conservation outcomes. These results are encouraging because 89% of World Bank projects that are close to IBAs are environmentally sensitive projects (so-called Category A and Category B projects) subjected to the organization’s most stringent safeguards. However, the limitations of our evaluation design do not allow us to rule out the possibility that World Bank projects had positive or negative effects that were undetectable.

具有保护意义的地点附近的世界银行开发项目对当地的影响

我们使用树木覆盖变化数据和原地状态、压力和响应监测数据评估了世界银行开发项目对具有公认保护意义的地点（重要鸟类和生物多样性区 [IBA]）的当地影响。与世界银行项目地点相邻的 IBA 和远离世界银行项目地点的一组匹配的 IBA 具有相似的树木损失率和相似的保护结果原位测量。因此，我们没有发现世界银行项目对树木覆盖或保护成果的任何重大净负面影响。这些结果令人鼓舞，因为接近 IBA 的世界银行项目中有 89% 是受到该组织最严格保护措施的环境敏感项目（所谓的 A 类和 B 类项目）。然而，
