In this paper we examine ways Sahelian floodplain fishers have adapted to the strong environmental variations that have affected the region in the last two decades. We analyse their vulnerability and adaptive capacity in the face of expected changes in rainfall combined with the predicted effects of dam construction. Data from the Inner Niger Delta in Mali were used to show that fishers were highly sensitive to past and recent variations in the hydro-climatic conditions.
Suspending horticulture in sacks above the ground can result in higher levels of productivity for vegetables when the challenges of unfertile or saline soil, flooding, waterlogging, and land and water constraints are regularly encountered. Previously used feed and fertilizer sacks are filled with a high-productivity soil mixture. Vegetables are grown on the top and/or in holes cut into the sides of the sacks. While growing vegetables in sacks has existed for many years in Bangladesh, the technique has been modified by WorldFish in collaboration with farmer researchers.
The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability of people in four villages that are experiencing different levels of soil salinity.
Fish are a significant source of income and food security in Uganda, highly vulnerable to climate and non-climate related drivers of change. This study examines the vulnerability of the fish sector in Uganda as it relates to the predicted impacts from climate change and variability, using the concept of the value chain. The specific purpose of the study was to identify current and potential impact pathways of climate change and corresponding adaptation strategies in fish value chains.
The Asia-Pacific's Coral Triangle is defined by its extremely high marine biodiversity. Over one hundred million people living in its coastal zones use this biodiversity to support their livelihoods. Hundreds of millions more derive nutritious food directly from the region's marine resources and through local, regional and global trade. Biodiversity and its values to society are threatened by demographic and habitat change, rising demand, intensive harvesting and climate change.
A habitat is the environment where species such as fish live, feed and breed. A small, specialized area of a habitat (a microhabitat) can be created and managed as a way to attract and encourage a species to use the environment. These microhabitats help maintain the biodiversity of ecosystems, which in turn support livelihood activities and the production of food. This brief describes the use of fish ring microhabitat developed by WorldFish for use in rice fields in Bangladesh and its benefit.
The Republic of Kiribati is a vast South Pacific island group with one of the largest exclusive economic zones (EEZs) in the world. Kiribati waters support a wealth of marine fisheries activities. These activities occur in oceanic, coastal and inshore environments and range from large, foreign, industrial-scale oceanic fishing operations to small-scale, domestic, inshore subsistence fisheries, aquaculture and recreational fisheries.
Animal source food production globally already faces increasing pressure because of negative environmental implications, particularly because of greenhouse gas emissions. As livestock and aquaculture are important sources of livelihood, it is necessary to find suitable solutions to convert these industries into economically viable enterprises, while reducing the ill effects of global warming. The most evident and important effects of climate change on livestock production will be mediated through changes in feed resources.
Increases in fish demand in the coming decades are projected to be largely met by growth of aquaculture. However, increased aquaculture production is linked to higher demand for natural resources and energy as well as emissions to the environment. This paper explores the use of Life Cycle Assessment to improve knowledge of potential environmental impacts of future aquaculture growth. Different scenarios of future aquaculture development are taken into account in calculating the life cycle environmental impacts.
Climate change with its attendant geophysical hazards is well studied. A great deal of attention has gone into analyzing climate change impacts as well as searching out possible mitigating adaptive strategies. These matters are very real concerns, especially for coastal communities. Such communities are often the most vulnerable to climate change, since their citizens frequently live in abject poverty and have limited capacity to adapt to geophysical hazards.
