Smallholder agricultural systems, strongly dependent on water resources and investments in shared infrastructure, make a significant contribution to food security in developing countries. These communities are being increasingly integrated into the global economy and are exposed to new global climate-related risks that may affect their willingness to cooperate in community-level collective action problems. We performed field experiments on public goods with private and collective risks in 118 small-scale rice-producing communities in four countries. Our results indicate that increasing the integration of those communities with the broader economic system is associated with lower investments in public goods when facing collective risks. These findings indicate that local public good provision may be negatively affected by collective risks, especially in communities more integrated with the market economy.
小农农业系统严重依赖水资源和对共享基础设施的投资，对发展中国家的粮食安全做出了重大贡献。这些社区正日益融入全球经济，并面临新的全球气候相关风险，这些风险可能影响它们在社区层面集体行动问题上的合作意愿。我们在四个国家的118个小规模水稻种植社区进行了有关具有私人风险和集体风险的公共物品的实地实验。我们的结果表明，当面临集体风险时，这些社区与更广泛经济体系融合程度的提高与公共物品投资的减少相关。这些发现表明，地方公共物品的提供可能会受到集体风险的负面影响，尤其是在与市场经济联系更紧密的社区。
