Climate change and its impact on the agricultural sector in developing economies is a matter of considerable academic and political debate. This paper examines the impact of climate change and variability on Sri Lankan agriculture and identifies the potential adaptation practices and their impacts on rice productivity. More specifically, this study investigates how farming households’ decisions to adapt to climate change affects agricultural productivity in the Batticaloa district of Sri Lanka. The data were collected through a primary survey of 238 farming households. We employ a simultaneous equations model with endogenous switching to investigate the differing effects of adaptation on adapters and non-adapters. The findings show that most farmers perceive there are adverse climate change impacts on their agricultural production. We also find that farmers’ adaptation measures substantially boost rice yields. Moreover, it is shown that such strategies would benefit both adapters and non-adapters Farmers’ access to climate related information, education, membership in farmer organizations and size of plots are found to play a key role in the adaptation process. Overall, this study provides empirical evidence of the positive impact of adaptations on food productivity and farm income, thus suggesting the need for policy interventions that enhance farmers uptake of strategies against climate change impacts.

斯里兰卡农业适应气候变化影响的经济分析：内生转换回归分析


气候变化及其对发展中经济体农业部门的影响是一个引起大量学术和政治争论的问题。本文研究了气候变化和变率对斯里兰卡农业的影响，并确定了潜在的适应措施及其对水稻生产力的影响。更具体地说，本研究调查了农户适应气候变化的决定如何影响斯里兰卡拜蒂克洛地区的农业生产力。数据是通过对238户农户的初步调查收集的。我们采用具有内源切换的联立方程模型来研究适应对适配器和非适配器的不同影响。调查结果表明，大多数农民认为气候变化对其农业生产产生不利影响。我们还发现农民的适应措施大大提高了水稻产量。此外，研究表明，此类策略将使适应者和非适应者受益。农民获得气候相关信息、教育、农民组织成员资格和地块大小在适应过程中发挥着关键作用。总体而言，这项研究提供了适应措施对粮食生产力和农场收入产生积极影响的经验证据，从而表明需要采取政策干预措施，加强农民对应对气候变化影响的战略的采用。
