研究降雨减少对意大利南部谷物生产的短期和长期负面影响,发现提高作物空间多样性可缓解冲击、增强系统恢复力并维持生产力。

Abstract

This paper investigates the dynamic effects of rainfall shocks on agroecosystems productivity. The analysis estimates a panel data model of cereal production in southern Italy. It documents the adverse effects of a reduction in rainfall on the agroecosystem productivity both in the short run and the long run. It investigates how increasing the level of spatial crop diversity can mitigate this negative impact. The empirical evidence shows how higher diversity supports resilience and maintains the system productivity under challenging climatic conditions. <i></i>
