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.
The authors discuss how the fisher community and the government shared responsibility over time for regenerating and conserving fishery resources in San Salvador Island, Philippines, and rose above the obstacles associated with a de facto open access fishery. The article highlights the creation, management, and impact on ecosystem health, both natural and human, of a marine reserve and sanctuary. It examines key events and arrangements during three distinct phases: pre-project (before 1989), project phase (1989-1993), and post-project (1994-1998).
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.
Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate of 4000, 5000, and 6000 ha-1 in treatments T1, T2, and T3, respectively. Water quality was suitable for fish culture. Significantly higher growth was observed in T1 as compared to other treatments. SGR ranged from 1.26 to 1.51. Survival varied between 79% and 88% with treatment T1 producing the highest survival.
The North Sea provides a useful model for considering forage fish (FF) within ecosystem-based management as it has a complex assemblage of FF species. This paper is designed to encourage further debate and dialogue between stakeholders about management objectives. Changing the management of fisheries on FF will have economic consequences for all fleets in the North Sea. The predators that are vulnerable to the depletion of FF are Sandwich terns, great skua and common guillemots, and to a lesser extent, marine mammals.
WorldFish, with funding support from the European Commission (EC), is undertaking a project with sites in Indonesia, Philippines, Solomon Islands and Tanzania. Titled Implementing an Ecosystem Approach to Fisheries (EAF) in Small-scale Tropical Marine Fisheries, the project commenced in December 2011 and is set to finish by December 2014. The project has adopted an EAF framework with the aim of improving small-scale fisheries (SSF) management in the four countries – a significant step to help reduce poverty.
The main purpose of the study is to determine whether non-use values exist among residents of Quezon City, hundreds of kilometers away from Tubbataha Reefs. The dichotomous choice contingent valuation method (CVM) was employed across 800 randomly selected respondents, 400 of which were personally interviewed (PI) and 400 were asked to accomplish self-administered (SA) questionnaires, 198 of the latter were found useable for the study.
This report summarizes activities carried out by WorldFish under Agreement CT09 Amendment No.2 dated 31 March 2010 between WorldFish and WWF, under the Coral Triangle Support Partnership (CTSP) project. The overall goal of the five-year CTSP project is “to improve the management of biologically and economically important coastal and marine resources and associated ecosystems that support the livelihoods of peoples and economies in the Coral Triangle”.
This paper reviews the coastal fishery resources of Bangladesh emphasizing the coastal environment, capture fisheries and management issues relative to the sector. Bangladesh’s Exclusive Economic Zone (EEZ) covers an area of about 166 000 km2. This area has abundant natural resources such as fish, shrimps, crabs and other marine products. Shrimp and fish trawling is the most important economic activity in this area. The fishery sector makes a significant contribution to the national economy in terms of foreign exchange, income generation and employment.
This brochure is part of a series that collectively detail how a community-based assessment of climate change was used in partnership with coastal communities and provincial and national-level stakeholders in Timor-Leste and Solomon Islands. The assessment contains four distinct, but related, steps focused on supporting community-level decision-making for adaptation through a series of participatory action research activities. Each brochure in this series details a specific activity in the four-step assessment.
