India's North Eastern Region comprises eight land-locked states and has a total population approaching 46 million, made up of approximately 220 ethnic communities. A high demand for fish prevails in the region as 90–100% of the population prefers fish in their daily diet. The region faces climate change-related issues at various levels and with a range of impacts on the inland fisheries sector. The period 1951 to 2010 saw a significant increase in annual mean temperature in several states of the region (Arunachal Pradesh, Assam, Manipur, Sikkim, Mizoram, and Tripura). The highest increase in annual mean temperature was recorded in Sikkim (+0.05 °C yr-1) followed by Manipur (+0.03 °C yr-1). Significant changes in annual rainfall pattern were also recorded during the same time period in the region: four of the eight states (Assam, Arunachal Pradesh, Sikkim, and Nagaland) experienced a decreasing trend, and the remaining four (Meghalaya, Manipur, Tripura, and Mizoram) an increasing trend. The highest increase in annual rainfall was recorded in Meghalaya (+14.68 mm yr-1) during this period. The change in seasonal trend of mean temperature and the erratic rainfall pattern in the region have had profound impacts on the traditional fisheries of the region. This study outlines these impacts and suggests potential adaptation actions that may be implemented to cope with climate change.

气候变化引发的挑战对印度东北地区渔业的影响及未来发展

印度东北部地区由八个内陆邦组成，总人口接近 4600 万，由大约 220 个民族社区组成。该地区对鱼的需求很高，因为 90-100% 的人口在日常饮食中更喜欢鱼。该地区在各个层面都面临与气候变化相关的问题，并对内陆渔业部门产生一系列影响。1951 年至 2010 年期间，该地区几个州（阿鲁纳恰尔邦、阿萨姆邦、曼尼普尔邦、锡金、米佐拉姆邦和特里普拉邦）的年平均气温显着上升。锡金（+0.05 °C yr-1）的年平均气温增幅最高，其次是曼尼普尔邦（+0.03 °C yr-1）。在同一时期，该地区的年降雨模式也发生了显着变化：八个州中有四个（阿萨姆邦、阿鲁纳恰尔邦、锡金和那加兰邦）呈下降趋势，其余四个（梅加拉亚邦、曼尼普尔邦、特里普拉邦和米佐拉姆邦）呈上升趋势。在此期间，梅加拉亚邦（+14.68 mm yr-1）的年降雨量增幅最大。该地区平均气温季节性变化趋势和降雨格局不规律，对该地区的传统渔业产生了深远的影响。本研究概述了这些影响，并提出了应对气候变化的潜在适应行动。该地区平均气温季节性变化趋势和降雨格局不规律，对该地区的传统渔业产生了深远的影响。本研究概述了这些影响，并提出了应对气候变化的潜在适应行动。该地区平均气温季节性变化趋势和降雨格局不规律，对该地区的传统渔业产生了深远的影响。本研究概述了这些影响，并提出了应对气候变化的潜在适应行动。
