Ecosystem services and their role in alleviating poverty are centered on a set of gendered social relations. The understanding of these relations between men and women in aquatic ecosystems can unveil gender-based opportunities and constraints along the value chains of the ecosystem services. A gender discourse perspective on participation of actors of an ecosystem can further facilitate the understanding of the complex and subtle ways in which gender is represented, constructed, and contested. This paper analyses the barriers to the participation of women in the fishing industry.
This poster shows the importance of mangroves conservation along the coast of Solomon Islands.
This paper summarizes the major findings in modelling and analysing agroecosystems using ECOPATH.
This document provides a description of the general freshwater habitats found throughout the Ayeyarwady Basin. With a wide range of riverine and wetland habitats and high levels of species biodiversity, the Ayeyarwady River remains an ecologically important area and one of the world’s biodiversity hotspots. However, the habitats of the Ayeyarwady River, from the mountain’s rivers in the Eastern Himalayas to the Outer Delta Islands, are increasingly being subjected to intense and growing pressure from habitat loss, degradation and fragmentation, and over-exploitation of natural resources.
After commencing with a summary of the current status, importance and productivity of natural wetlands, the chapter reviews the contribution of wetland ecological functions to sustaining vital ecosystem services. Wetlands are vulnerable to a range of anthropogenic pressures, notably land use change, disruption to regional hydrological regimes as a result of abstraction and impoundment, pollution and excessive nutrient loading, the introduction of invasive species and overexploitation of biomass, plants and animals.
A preliminary mass-balance trophic model was constructed for the coastal fisheries ecosystem of the West Coast of Peninsular Malaysia (0 - 120 m depth). The ecosystem was partitioned into 15 trophic groups, and biomasses for selected groups were obtained from research (trawl) surveys conducted in the area in 1987 and 1991. Trophic interactions of the groups are presented. The network analysis indicates that fishing fleets for demersal fishes and prawns have a major direct or indirect impact on most high-trophic level groups in the ecosystem.
An account is given of the methodology and findings of a holistic, ecosystemic investigation of the multispecies fisheries of Bukit Merah Reservoir in Malaysia in 1978-80. The need for sound biological and ecological understanding of the resources as a basis for management decision is demonstrated.
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.
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.
