摘要

目的:气候变化会破坏粮食供应,减少获得粮食的机会,并影响粮食质量。预估的温度升高、降水模式变化、极端天气事件变化以及可用水量减少都可能导致农业生产力下降。极端天气事件发生频率和严重程度的增加也会中断食品配送,预计未来极端天气事件发生后导致的食品价格飙升将更加频繁。温度升高会导致腐败和污染。本研究的总体目标是确定适应实践对气候变化的影响及其对农户农业生产的影响。研究方法:本文采用桌面研究回顾方法,对相关的实证文献进行回顾,以确定主题并提取知识空白。结果:研究发现,当地家庭倾向于采取多种适应策略来应对气候变率和变化的影响。目前的地方适应策略包括作物、多样化、改变种植日期、非农工作以及从农业到非农业活动的多样化。然而,大多数答复者采用作物多样化作为主要的适应战略。因为当地的作物多样化在一定程度上保证了好收成,尽管有些年份农民会报告作物的总损失。建议:该研究建议,政策应侧重于实施适应气候变化的措施,以促进农业生产

EFFECT OF ADAPTATION PRACTICES TO CLIMATE CHANGE ON AGRICULTURAL PRODUCTION BY FARMING HOUSEHOLD. A CRITICAL LITERATURE REVIEW
Purpose: Climate change can disrupt food availability, reduce access to food, and affect food quality. Projected increases in temperatures, changes in precipitation patterns, changes in extreme weather events, and reductions in water availability may all result in reduced agricultural productivity. Increases in the frequency and severity extreme weather events can also interrupt food delivery, and resulting spikes in food prices after extreme events are expected to be more frequent in the future. Increasing temperatures can contribute to spoilage and contamination. The general objective of the study was to establish the effect of Adaptation practices to climate change and its impact on agricultural production by farming household. Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps. Findings: The study found out the locals households prefer multiple adaptation strategies to counter the effects of climate variability and change. The current local adaptation strategies include crop, diversification, shifting planting dates, off farm jobs and diversifying from farm to non – farm activities. However majority of the respondents employ crop diversification as the main adaptation strategy. For the locals’ crop diversification does, to an extent, guarantees good harvests although there are years in which farmers report total crop losses Recommendations: The study recommends that policy efforts should be directed at enforcing adaptation measures of climate change in order to boost agricultural production
