摘要

本研究考察了古吉拉特邦农民对气候变化的看法以及缓解气候变化对农业部门不利影响的适应策略。它使用了从8个地区特意挑选的400名农民的农场级别信息。在此基础上,采用线性、非线性和对数线性生产函数模型考察了气候变化、农民适应策略和技术变革对古吉拉特邦农业生产的影响。描述性和实证结果表明,适应策略(即改变作物的显示时间、混合种植模式、灌溉设施、施用绿色和有机肥料、种子杂交品种、种植前种子潮湿、气候耐受性作物、有机耕作和技术)对农业生产产生积极影响。因此,农民的适应战略有助于减轻气候变化对农业部门的负面影响。最高气温和最低气温、降水和降雨对农业生产有负面影响。然而,当农民在种植中采用上述适应策略时,这些因素对农业部门的影响似乎是积极的。家庭规模、农民受教育程度、农民年收入、耕地面积、灌溉面积、技术成本、适宜技术和政府财政支持对古吉拉特邦农业增产有积极贡献。

Implications of Farmer’s Adaptation Strategies to Climate Change in Agricultural Sector of Gujarat: Experience from Farm Level Data
This study examined the farmer’s perception on climate change and adaptation strategies to mitigate the adverse effect of climate change in the agricultural sector of Gujarat. It used farm level information of 400 farmers who were purposely selected from 8 districts. Thereupon, linear, non-linear and log-linear production function models were used to examine the impact of climate change, farmer’s adaptation strategies and technological change on agricultural production in Gujarat. The descriptive and empirical results specify that adaptation strategies (i.e., change in showing time of crops, mixed cropping pattern, irrigation facilities, application of green and organic fertilizer, hybrid varieties of seeds, dampening of seed before planting, climate tolerate crops, organic farming and technology) have a positive impact on agricultural production. Thus, farmer’s adaptation strategies are useful to mitigate the negative impact of climate change in the agricultural sector. Maximum temperature and minimum temperature, precipitation and rainfall have a negative impact on agricultural production. However, the impact of these factors seemed positive in the agricultural sector when farmers apply aforementioned adaptation strategies in cultivation. Family size, education level of farmers, annual income of farmers, arable land, irrigated area, cost of technology, appropriate technology and financial support from government have a positive contribution to increase agricultural production in Gujarat.
