Improving the productivity of fisheries and aquaculture is vital to reducing hunger and poverty for millions of people in the developing world. Today, fish provides more than one billion poor people with most of their daily animal-source protein and, globally, more than 250 million people depend directly on fisheries and aquaculture for their livelihoods; millions more are employed in fisheries and aquaculture value chains.
Significant changes in our understanding of the interrelationships between aquaculture and poverty have occurred in the last decade. In particular, there is a growing realization that the impacts of aquaculture need to be assessed from a value-chain perspective rather than through a narrow production focus. In recent years, understandings of poverty and the forms, outcomes and importance of aquaculture have also shifted. Terms in current use are first clarified, including those related to scale and location of aquaculture.
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.
Resilience thinking is an important addition to the range of frameworks and approaches that can be used to understand and manage complex social–ecological systems like small-scale fisheries. However, it is yet to lead to better environmental or development outcomes for fisheries stakeholders in terms of food security, improved livelihoods and ecological sustainability.
These “Technical Guidelines for Economic Valuation of Inland Small-scale Fisheries in Developing Countries” are one of the outputs of the project on “Food security and poverty alleviation through improved valuation and governance of river fisheries in Africa”. The guidelines draw upon research results and experience gained during the course of the project.
Over 5 years of participatory on-farm research, market access, profitability, farming systems productivity and economic sustainability were compared on 100 small-scale farms in Central Cameroon. Integration technology based on the use of agricultural by-products as fishpond inputs was the driver for intensification. Over all farms, fishpond productivity increased from 498 kg to 1609 kg fish/ha (2145 kg/ha/yr). During the project period, the number of active fish farmers increased from 15 to 192 (including 55 farms which participated only through information exchange).
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.
The NEPAD-Fish for All Summit was held on 22–25 August 2005 in Abuja, Nigeria, to draw global attention to the vital role of fisheries and aquaculture in meeting Africa’s development agenda.
Commencing with a summary of the current status, importance and productivity of natural wetlands the contribution of wetland ecological functions to sustaining vital ecosystem services is then reviewed. Provisioning services, notably fish and water for irrigation or domestic and industrial purposes constitute important benefits derived by humanity from wetlands, whilst recognition is growing that supporting, regulating and cultural services supported by wetlands are critical for sustaining social-economic systems and ensuring human well-being.
In this chapter, the authors assess the vulnerability of aquaculture in the tropical Pacific to climate change. It begins by summarising recent and potential aquaculture production to set the scene for the sector, and then use the framework outlined in Chapter 1, based on exposure, sensitivity, potential impact and adaptive capacity, to evaluate the vulnerability of the main commodities for food security and livelihoods.
