Land use patterns and influences of protected areas on mangroves of the eastern tropical Pacific

Mangroves are one of the most productive ecosystems in the world, sustaining millions of coastal livelihoods. However, their area of occurrence has been greatly reduced over the last century. In this study, we identify potential drivers of land use and land cover change adjacent to mangroves on the Pacific shorelines of Colombia, Panama and Costa Rica. We also evaluate the effectiveness of protected areas at halting mangrove deforestation between 2000 and 2012. Across all countries, agriculture was the most dominant land use type adjacent to mangroves, inside and outside protected areas.

Including GHG emissions from mangrove forests LULUC in LCA: a case study on shrimp farming in the Mekong Delta, Vietnam

Mangrove forests have been recognized as important regulators of greenhouse gases (GHGs), yet the resulting land use and land-use change (LULUC) emissions have rarely been accounted for in life cycle assessment (LCA) studies. The present study therefore presents up-to-date estimates for GHG emissions from mangrove LULUC and applies them to a case study of shrimp farming in Vietnam.

Drivers of mangrove ecosystem service change in the Sundarbans of Bangladesh

Mangroves are now well known to provide a range of ecosystem services that benefit local populations, though such ecosystem services are at risk from mangrove deforestation and degradation across much of the tropics. This study aimed to identify the natural and anthropogenic drivers of change that affect ecosystem services of the Sundarbans mangrove forest.

Conserving womangroves: Assessing the impacts of improved cooking stoves on resource management in Langalanga Lagoon, Solomon Islands

Firewood harvesting is a major threat to mangrove ecosystems in Solomon Islands. Improved cooking stoves could reduce firewood use and thereby ease pressure on mangroves. We conducted a field-based experiment in Langalanga Lagoon to evaluate this theory of change. Our results suggest that the so-called ‘kiko stove’, an improved cooking stove that is widely promoted in Solomon Islands, is not more efficient than cooking on an open fire in terms of cooking time and wood consumption.

Vulnerability of mangroves, seagrasses and intertidal flats in the tropical Pacific to climate change

Mangroves and seagrasses are of special interest to coastal fisheries worldwide because of the role they play in providing nursery areas for commonly harvested fish and invertebrates. Although the ecology of fish and invertebrates associated with mangroves and seagrasses in the tropical Pacific is not well understood compared with other parts of the world, the connectivity among mangroves, seagrasses, intertidal flats and coral reefs indicates that mangroves and seagrasses throughout the region provide a similar function to such habitats elsewhere.

Status and management of the Java sea fisheries

The Java Sea is a major fishing ground in Indonesia contributing 31% of the national marine fisheries production. Demersal and small pelagic fishery resources account for most production in the area. During the 1960s and 1970s, strong demand for fish, which in Indonesia resulted from both increased human population and increased per capita fish consumption, stimulated the development of fishing in the Java Sea. This led to development of up-stream and down-stream industries, increases in employment opportunities, and increases in the number of fishers and fishing households.

Review of national fisheries situation in Sri Lanka

Fisheries are an important source of protein and employment for Sri Lanka’s population. The declaration of the Exclusive Economic Zone (EEZ) in 1976 gave the country a water area larger than its land area. The coastal fisheries resources consist of small and large pelagic fish, demersal and coral reef fish, invertebrates, shrimps and crabs. The small pelagic fish contribute 70% of the catch from coastal waters with an estimated annual production of 152 752 t in 1997.

Research Program on Aquatic Agricultural Systems: Program summary: Solomon Islands

The Program will achieve impact at multiple scales (household, community, province and national as well as amongst program countries) through pathways that include partnerships, knowledge sharing and learning. In Solomon Islands significant benefits will be achieved through direct engagement with partners, including communities in specific research sites in selected program hubs. Of a total population of just over half a million people, 75% of Solomon Islanders are subsistence-oriented small holder farmers and fishers.

Preliminary analysis of demersal fish assemblages in Malaysian waters

Spatial and temporal variations of the demersal fisheries resources of Malaysia were studied using multivariate analysis of their abundance (biomass) from research trawl surveys in relation to geographical and environmental parameters. TWINSPAN results indicate that the demersal resources of Malaysia can be geographically divided into five major species assemblages. Two assemblages are in Peninsular Malaysia and three assemblages are in Sabah and Sarawak waters.
