Functional aquatic ecosystems, inland fisheries and the Millennium Development Goals

Freshwater allocation in an environment of increasing demand and declining quality and availability is a major societal challenge. While biodiversity and the needs of local communities are often in congruence, the over-riding necessity of meeting national demands for power, food and, increasingly, mitigation of the hydrological effects of climate change, often supersedes these.

A framework for understanding climate change impacts on coral reef social-ecological systems

Corals and coral-associated species are highly vulnerable to the emerging effects of global climate change. The widespread degradation of coral reefs, which will be accelerated by climate change, jeopardizes the goods and services that tropical nations derive from reef ecosystems. However, climate change impacts to reef social-ecological systems can also be bi-directional.For example, some climate impacts, such as storms and sea level rise, can directly impact societies, with repercussions for how they interact with the environment.

Food security versus environment conservation: A case study of Solomon Islands' small-scale fisheries

The sustainable management of small-scale fisheries in coral reef ecosystems constitutes a difficult objective not least because these fisheries usually face several worsening pressures, including demographic growth and climate change. The implications are crucial in terms of food security as fish represents the major protein source for local populations in many regions reliant on small-scale fisheries. The case of the Solomon Islands’ fishery presented in this paper represents an illustrative example of these issues.

Food security and the coral Triangle Initiative

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.

Fisheries and aquaculture: The importance of fish for food and nutritional security

This working paper is an attempt to distil what is known currently about the likely impacts of climate change on the commodities and natural resources that comprise the mandate of CGIAR and its 15 Centres. In this WorldFish contribution, a summary is given on the importance of fisheries and aquaculture on food nutrition and security.

Fish ring microhabitats: Resilience in rice field fisheries

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.

Fish for the future: Fisheries development and food security for Kiribati in an era of global climate change

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.

Feed resources vis-à-vis livestock and fish productivity in a changing climate

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.

Exploratory analysis of resource demand and the environmental footprint of future aquaculture development using Life Cycle Assessment

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.

Evaluating the flow regulating functions of natural ecosystems in the Zambezi River Basin

By mitigating the vagaries of climate variability, agricultural water storage is widely anticipated to make a key contribution to climate change adaptation in Africa. However, if the planning of water storage is not improved, it is likely that many investments will fail to fully deliver intended benefits. This report describes the agricultural water storage continuum and some of the possible implications of climate change.
