Climate change negatively impacts rice productivity in different parts of Africa. As a matter of necessity, farmers must respond to changing the climate by choosing adaptation strategies that increase their productivities. Incidentally, studies that documented the impact of climate change adaptation actions of farmers on rice productivity are few. This study therefore analyzed the impact of climate change adaptation decisions of farmers on the profitability of rice production using cross-sectional data gathered from 240 rice farmers selected from Ebonyi State, an important rice-producing State in Nigeria, Africa's most populous country. Using descriptive statistics, multivariate probit regression, instrumental variable regression and endogenous treatment effect model, the study revealed that the common adaptation actions of rice farmers involved adoption of minimum tillage, bond and drainage, fertilizer, crop diversification, livelihood diversification, improved rice varieties, pesticide, nursery, and adjusting planting and harvesting dates. The study found several significant interactions between the choice of climate change adaptation actions and socio-economic, farm, institutional and location characteristics of rice farmers. The result further revealed that multiple adaptation decisions of farmers significantly increased returns to scale and profit of rice production. The study concludes that adaptation decisions are effective in increasing the profitability and returns to scale of rice production in the area and other regions with similar geographical, meteorological and socio-economic contexts.

适应气候变化是否会提高水稻的生产力？尼日利亚埃博尼州的经验教训

气候变化对非洲不同地区的水稻生产力产生负面影响。作为必要的问题，农民必须通过选择提高生产力的适应策略来应对气候变化。顺便说一句，记录农民气候变化适应行动对水稻生产力影响的研究很少。因此，本研究使用从非洲人口最多的国家尼日利亚的一个重要稻米生产州 Ebonyi 州选出的 240 名稻农收集的横断面数据分析了农民适应气候变化的决定对稻米生产盈利能力的影响。使用描述性统计、多元概率回归、工具变量回归和内生治疗效果模型，研究表明，稻农的共同适应行动包括采用少耕、粘结和排水、化肥、作物多样化、生计多样化、改良水稻品种、杀虫剂、育苗以及调整种植和收获日期。该研究发现，气候变化适应行动的选择与稻农的社会经济、农场、制度和区位特征之间存在一些显着的相互作用。结果进一步表明，农民的多重适应决策显着提高了水稻生产的规模收益和利润。该研究得出的结论是，适应决策在提高该地区和其他具有相似地理、气象和社会经济背景的地区的水稻生产的盈利能力和规模回报方面是有效的。
