Multiple water use as an approach for increased basin productivity and improved adaptation: a case study from Bangladesh

This study, supported by the Challenge Program Water and Food (CPWF-Project 35), demonstrates the case of multiple-use of water through seasonal aquaculture interventions for improved rice–fish production systems in the Bangladesh floodplains. The project focused on community-based fish culture initiatives, increasingly adopted in the agro-ecological zones of the major floodplains of the Padma, Testa, and Brahmaputra basin. The productivity of water and fish is used as an indicator to explain this case.

Mangrove management in Solomon Islands: Case studies from Malaita Province

Mangroves are an important resource for the rural coastal people of Solomon Islands. Mangrove forests are critical for food security and the livelihoods of coastal communities in Solomon Islands. In particular, mangroves are an important source of food (e.g. fish, mangrove fruit, shells and crabs) and timber (e.g. for firewood and building materials).

Management of coastal fisheries in Vietnam

The fisheries sector of Vietnam plays an important role in the social and economic development of the country. The sector contributes about 3% of the GDP and fish contributes about 40% of animal protein consumption in the country. In 1999, total fisheries production amounted to 1.8 million t. Of this, 1.2 million t was derived from marine capture fisheries and 0.6 million t from aquaculture. Fish exports were valued at US$971.12 million in the same year. Vietnam’s marine fisheries and coastal aquaculture have further potential for development.

The forgotten service: food as an ecosystem service from estuarine and coastal zones

In this chapter, we review in detail the existing body of literature and knowledge related to the provision of food in estuaries and coastal zones. Both aquatic and terrestrial commodities are considered. The chapter highlights not only the importance of the terrestrial zone in overall food provision but also the substantial contribution of aquatic coastal resources. The various problems that the coastal zone faces in sustaining this important provisioning service in the face of increasing pressure and demands from other sectors are highlighted.

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.

An ecosystem model of San Pedro Bay, Leyte, Philippines: initial parameter estimates

A mass-balance model of the trophic structure of San Pedro Bay, Leyte Province, Philippines was constructed using the Ecopath modeling software. The model is composed of 16 ecological groups (13 consumer, 2 producers, 1 detritus groups). The input parameters were obtained from the resource assessments studies conducted in 1994 - 95 and the biomass of Leiognathidae, an important group of small demersal fishes was estimated from trawl survey data using the swept- area method. The model indicated that the average trophic level of the fishery catches is 3.25.

Economic analysis of climate change adaptation strategies in selected coastal areas in Indonesia, Philippines and Vietnam

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.

Community-based adaptation to climate change in Solomon Islands: Lessons learned from Gizo communities, Western Province

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”.

Carrying capacities and site selection within the ecosystem approach to aquaculture

The growth in world aquaculture required to meet the demands of society will result in ever-increasing pressure upon aquatic and terrestrial resources. There are also potential consequences on the environment and on biodiversity, as well as inevitable societal impacts. There is growing adoption of aspects of the ecosystem approach to aquaculture (EAA), which takes a holistic view of the developments in the sector in an attempt to enable sustainable growth while avoiding negative effects.

Seasonality dynamics for investigating wetland-agriculture nexus and its ecosystems service values in Chibuto, Mozambique

This study is a subsection of CPWF-30 (Challenge Program on Water and Food) that centers on investigating the wetland, agriculture, and livelihoods interactions. Chibuto, the floodplain of Changane River in Mozambique is a representative downstream site for the Limpopo sub-catchment. It largely serves as an agro-ecosystem with agricultural, grazing, and fiber collection as the prominent set of ecosystem services. The present analysis is a three-tier framework conceptualized to develop a synoptic overview of spatial, social, and economic elements that governs the system dynamics.
