Aquaculture is critically important to food and nutrition security in Bangladesh. It provides 60 percent of animal protein requirements for Bangladeshis and makes up 3.65 percent of the country’s GDP . It has pulled more than 2 million of the 18 million Bangladeshis who came out from poverty. However, the sector is vulnerable and impacted by climate variability. High temperatures can affect fish growth and reproduction and erratic rainfall and fluctuation in temperature impact fish spawning. Shallow pond fish are particularly vulnerable to high temperatures.
Climate change can alter conditions that sustain food production and availability, with cascading consequences for food security and global economies. Here, we evaluate the vulnerability of societies to the simultaneous impacts of climate change on agriculture and marine fisheries at a global scale.
The role of aquatic animals in global food and nutrition security is increasingly recognised. The global demand for fish is increasing, leading to a need to significantly increase its supply. Securing future fish supplies through sustainable production is a challenge as major resources such as fresh water and land are becoming limited worldwide. Aquaculture and capture fisheries face various threats from both human-mediated and natural environmental change, including climate change. Aquaculture systems and practices are vulnerable to such changes.
Climate-smart aquaculture provides a means to ensure sustainable fish supply to those who experience negative impacts of climate change. However, there has been little research on possible benefits of climatesmart aquaculture for enabling the empowerment of women who are fish farmers. This brief outlines the key findings of a study that investigated a WorldFish homestead pond intervention, which is considered a climate-smart practice. In particular, the study assessed whether this intervention acted as an enabler toward empowerment for women in two divisions in rural Bangladesh.
The term ‘Blue Economy’ is increasingly used in various marine sectors and development frameworks. For it to be a truly useful approach, however, we argue that social benefits and equity must be explicitly prioritized alongside environmental and economic concerns. This integration of social dimensions within the Blue Economy is required to ensure that marine economic sectors contribute to achieving sustainable development goals.
Failure to address unsustainable global change is often attributed to failures in conventional environmental governance. Polycentric environmental governance—the popular alternative—involves many centres of authority interacting coherently for a common governance goal. Yet, longitudinal analysis reveals many polycentric systems are struggling to cope with the growing impacts, pace, and scope of social and environmental change. Analytic shortcomings are also beginning to appear, particularly in the treatment of power.
A fish agri-food system is an interconnected and interdependent system involving components of fish production through to processing, marketing and consumption. The CGIAR Research Program on Fish Agri-Food Systems (FISH) is a collaborative global partnership that aims to enhance the sustainability, productivity and resilience of fish agri-food systems, contributing to global goals for poverty reductions, food and nutrition security, and improved resilience of natural resource systems.
Climate variability has a profound influence on fisheries and agriculture in South Asia, including the service industry and value chains. Progress in weather and sub-seasonal/seasonal forecasting has significantly increased the information available. Yet gaps still exist in the delivery and impact of climate information services, including reliability, uncertainty, scaling and delivery.
Climate variability has a profound influence on fisheries and agriculture in South Asia. CaFFSA will innovate in the delivery of climate services to 330,000 farm households in India (Andhra Pradesh and Odisha states) and 150,000 fish farming households in Odisha and Bangladesh (Barisal, Sylhet and Khulna divisions). Timely, reliable and contextualized climate information will profoundly change the climate risk equation in sectors that underpin the food security of millions. The project will build on the existing expertise of CGIAR and partnerships with national agencies, agricultural service and credit institutions to design and deliver scalable products, with an aim to reach more than 600,000 people by 2021.
This work was implemented as part of the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS), which is carried out with support from CGIAR Fund Donors and through bilateral funding agreements. This project is led by the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).
Although about 43% of the African continent is considered arid and water-poor, it supports the livelihoods of nearly 485 million people. This part of the continent is largely ignored as having potential for aquaculture development, but it has underground water sources (including brackish water aquifers), dams, seasonal ponds and pools from abandoned open-cast mines that all could be used for aquaculture. Furthermore, the abundant solar radiation is an inexpensive and sustainable source of energy for operating closed and open aquaculture systems and for preserving postharvest fish and fish products. Exploiting this potential requires research and development of climate-smart and efficient aquaculture technologies adaptable to water-deficient conditions. The ACliSAT project aims to improve rural livelihood and households’ resilience through aquaculture in Egypt, Ethiopia and Eriteria by sustainably increasing fish production and productivity, nutrition and income generation of fish farmers. The 3-year project will leverage improvements in pond designs and construction for efficient water use. It will also leverage improvements in feed production and feeding technology, as well as adaptation and improved culture practices of Nile Tilapia for different water and temperature conditions. Using these improvements, the project will stimulate growth in emerging and existing aquaculture sectors by sharing knowledge with fish farmers, research centers, extension agencies and service providers on aquaculture technologies and improving the engagement of women and youths in aquaculture activities.
