Global climate change has seriously threatened agriculture and connected sectors, especially in developing countries like India. The Brahmaputra Valley in Assam, Northeast India, is vulnerable to climate change due to its agrarian economy, fragile geo-ecological setting, recurrent floods and droughts, and poor socioeconomic conditions of the farmers. The climate-induced hindrances faced by the rice farming community of this region and the local adaptation practices they employ have not been adequately studied. Therefore, we carried out a survey among 635 rice farmers across four agro-climatic zones of Assam, namely the Upper Brahmaputra Valley Zone, North Bank Plain Zone, Central Brahmaputra Valley Zone, and Lower Brahmaputra Valley Zone, to understand how they perceive and respond to climatic changes. The survey revealed that all the respondents have perceived an increase in ambient temperature, and 65% of the respondents have perceived a slight change in rainfall characteristics over the years. Most farmers reported adjusting the existing farming practices and livelihood choices to adapt to the changing climate. Farming adjustments were made mainly in terms of field preparation and management of water, rice variety, nutrients, and pests. Environmental variables like rainfall, flood, drought, and pest level, and socioeconomic variables like family size, education, farming experience, training, digital media exposure, and land area were found to influence farmers' adaptation choices. The findings imply that policies to strengthen flood, drought, pest management, education, land-use planning, agricultural training, and digital media applications in agriculture are needed for effective climate change adaptation in this region.
全球气候变化严重威胁到农业及相关产业,特别是在印度这样的发展中国家。印度东北部的阿萨姆邦的布拉马普特拉河谷由于其以农业为基础的经济、脆弱的地理生态环境、频繁发生的洪水和干旱以及农民贫困的社会经济条件,极易受到气候变化的影响。该地区水稻种植社区面临的气候障碍以及他们采用的地方适应实践尚未得到充分研究。因此,我们在阿萨姆邦的四个农业气候区(上布拉马普特拉河谷区、北岸平原区、中布拉马普特拉河谷区和下布拉马普特拉河谷区)对 635 名水稻种植户进行了调查,以了解他们如何感知和应对气候变化。调查显示,所有受访者都感受到了环境温度的升高,65%的受访者认为近年来降雨量特征略有变化。大多数农民报告说,他们调整了现有的耕作实践和生计选择以适应不断变化的气候。耕作调整主要是在田地准备和水管理、水稻品种、养分和病虫害管理方面进行的。环境变量(如降雨、洪水、干旱和病虫害水平)和社会经济变量(如家庭规模、教育、耕作经验、培训、数字媒体接触和土地面积)被发现影响了农民的适应选择。调查结果表明,该地区需要加强洪水、干旱、病虫害管理、教育、土地利用规划、农业培训和农业数字媒体应用方面的政策,以实现有效的气候变化适应。
