摘要

气候变化是一种全球性的现象,是当前最紧迫的问题之一,也是新兴的环境问题之一。气候变化的影响是多方面的,对地球生命和生物多样性的各个方面都有不可磨灭的影响。渔业和水产养殖被认为是印度次大陆经济的一个重要分支,与农业和相关部门有关。数以百万计的利益攸关方直接或间接依赖水产养殖和渔业部门维持生计,他们大多属于经济金字塔的底层,收入较低,工作无组织,社会经济脆弱性较大。他们往往处于弱势地位,而且最容易受到变幻莫测的气候变化的影响。与艾拉、法尼、布尔等热带气旋以及最近的安潘和尼萨尔加等热带气旋有关的不稳定的温度和降雨模式、暴雨潮、盐度入侵、海面温度升高、海洋酸化、淡水资源盐碱化,给印度东西海岸以及孟加拉国沿海的渔业和水产养殖部门造成了严重损失。近十年来,与全球气候变化相关的自然灾害频发已成为全球普遍现象。因此,了解全球气候变化对渔业和水产养殖部门的各种影响之间的关键相互作用是相关的。渔业和水产养殖部门的创新和企业机会的适当孵化可能为增长和扩散提供必要的氧气。这也可以帮助依赖鱼类和水产养殖资源的其他发展中经济体制定类似的整体办法。这次科学交流通过一个简短的评论来阐明这些方面。导言:自上个世纪以来,由于全球气候的波动,全球生态系统正面临着意想不到的变化(Guldberg和Bruno, 2010;帕乔里,2007))。对人类活动的全面了解

Brief commentary on the impact of global climate change on fisheries and aquaculture with special reference to India
Climate Change is a global phenomenon and is one of the burning glitches and emerging environmental issues in present time. The impact of climate change is manifold and having indelible impact on all aspects of earth life and biodiversity. Fisheries and Aquaculture have been considered as an important branch of Indian subcontinent economy associated with agriculture and allied sectors. Millions of stakeholders are dependent directly or indirectly on aquaculture and fisheriessector for their livelihood belonging mostly to the bottom of economic pyramid with lower incomes, unorganized jobs, greater socio-economic vulnerability. Often they are under privileged andmostly affected by the vagaries of climate change. Erratic temperature and rainfall patterns, storm-water surges, salinity invasion, increasing sea-surface temperature, oceanic acidification, salinization of freshwater resources associated with tropical cyclones such as Aila, Fani, Bulbul to the very recent Amphan and Nisarga has created a havoc loss in fisheries and aquaculture sector in both east and west coast of India as well as along Bangladesh coast. Frequent natural disasters associated with global climate change have been a common global phenomenon since last decade. Therefore, it is pertinent to understand the crucial interplay between multifarious impacts of global climate change on fisheries as well as aquaculture sector. Innovation and proper incubation of entrepreneurial opportunities in fisheries and aquaculture sector might provide the necessary oxygen for growth and proliferation. This can also help other developing economies relying on fish and aquaculture resources to develop a holistic approach on similar lines. This scientific communication throws light on these aspects through a brief commentary. INTRODUCTION: Ecosystems across the world are facing unanticipated changes due to fluctuations of global climate since the last century (Guldberg and Bruno, 2010; Pachauri, 2007)).
