The main purpose of this book is to assess how changes projected to occur under low (B1) and high (A2) emissions scenarios in 2035 and 2100 could derail plans by the Pacific Island countries and territories (PICTs) to use the sustainable benefits of fisheries and aquaculture to foster economic development, government revenue, food security and livelihoods.
Ce rapport présente les activités et les résultats de l’atelier Vision 2050: Changement climatique, pêche et aquaculture en Afrique de l’Ouest. Les objectifs de l’atelier étaient de discuter les questions critiques et les incertitudes auxquelles est confronté le secteur de la pêche et de l’aquaculture au Ghana, au Sénégal et en Mauritanie, d’élaborer des scénarios sectoriels pour 2050 et de discuter de l’implication de ces scénarios dans le contexte du changement climatique pour ces pays et la région ouest africaine.
The potential impacts of climate change on fishing communities and fishing supplies are profound. To tackle this issue involves 1. Strengthening science to inform adaptation needs and mitigation options. 2. Putting knowledge into policy and practice. 3) Collaboration for climate change adaptation.
There is an increasing ‘fish gap’ in sub-Saharan Africa (SSA), where fish supplies have failed to keep pace with the region’s growing demand. Despite the high dependence on fish for nutrition in much of the region, consumption is currently half the global average and declining. In SSA, as in many other regions globally, marine and inland capture fisheries resources are stagnating or decreasing, largely due to environmental or ecosystem changes and over-exploitation. Climate change is already altering the distribution of fish stocks and rainfall patterns upon which these fisheries depend.
Productivity enhancement has traditionally been the main focus of agricultural research to alleviate poverty and enhance food security of poor farmers in the developing world. Recently, the harmful impact of climate change, economic volatility, and other external shocks on poor farmers has led to concern that resilience should feature alongside productivity as a major objective of research.
Lake Chilwa is shared by Malawi and Mozambique, it supports an important fishery and its watershed is undergoing rapid population growth and increasing utilization for agricultural production. It is a shallow, closed basin lake with extensive surrounding wetlands; and it has suffered several desiccation events in the last century. To better understand the current condition of the lake, we monitored a suite of physical, chemical and biological parameters at approximately monthly intervals over an annual cycle in 2004–2005.
The Sundarbans mangrove ecosystem, shared by India and Bangladesh, is recognized as a global priority for biodiversity conservation. Sea level rise, due to climate change, threatens the long term persistence of the Sundarbans forests and its biodiversity. Among the forests’ biota is the only tiger (Panthera tigris) population in the world adapted for life in mangrove forests. Prior predictions on the impacts of sea level rise on the Sundarbans have been hampered by coarse elevation data in this low-lying region, where every centimeter counts.
This chapter examines the multiple dimensions of poverty and related 'state of being' such as vulnerability and social exclusion, with reference to several important aspects of vulnerability, including gender, climate change, HIV/AIDS and child labour.
International organizations are calling for fisheries to be included in a new global deal on climate change. A consortium of 16 organizations including the UN Environment Programme (UNEP), the Food and Agriculture Organization (FAO), the World Bank and the WorldFish Center issued a policy brief to delegates meeting in Bonn from June 1-12 for the latest round of UN climate talks. Their key message was outlined in a Commentary by two of the authors of the brief published May 28 on Nature Reports Climate Change.
