Do non-users value coral reefs?: Economic valuation of conserving Tubbataha Reefs, Philippines

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.

Sustainable Development in the Coral Triangle

If marine biodiversity is what you are after, then look no further than the Coral Triangle. This remarkable patch of water spans the seas between the six Indo-Pacific nations of Indonesia, the Philippines, Malaysia, Timor-Leste, Papua New Guinea, and the Solomon Islands. The tropical waters of the Coral Triangle are among the most biologically diverse – and environmentally vulnerable – regions of the world. The Coral Triangle’s coral reefs, mangrove forests, and seagrass beds are home to vast numbers of fish, sharks and rays, as well as sea turtles and marine mammals.

Blue Frontiers : Managing the environmental costs of aquaculture

This global review is a comprehensive analysis of global aquaculture production across all major species and farm production systems. The report aims to inform policy makers about the impacts of aquaculture on the environment and to stimulate debate on the optimal animal food production systems for tomorrow.
 

Biodiversity of Freshwater Ecosystems: status, trends, pressures and conservation priorities

Freshwater in the form of rivers, lakes, groundwater and wetlands offers us a remarkably diverse array of natural functions and ecosystem services. However, there is clear and growing scientific evidence that we are on the verge of a major freshwater biodiversity crisis: in the 30 years between 1970 and 2000, populations of more than 300 freshwater species have declined by ~55 percent while those of terrestrial and marine systems each declined by ~32 percent.

Payments for Mangrove Ecosystem Services

Mangroves are key coastal ecosystems that furnish valuable goods and services including water quality control, nursery habitats and storm protection. Additionally like other forests, mangroves have high rates of primary productivity and sequester (i.e., take up) large amounts of atmospheric carbon. Mangroves thus function as critical global sinks for carbon dioxide (a major greenhouse gas), and their conservation and restoration can play an important role in climate change mitigation in developing countries.

Conserving Natural Resources and Improving Livelihoods through Collaborative Management

Bangladesh is currently experiencing a steady loss of biodiversity in its protected areas: national parks, wildlife sanctuaries, game reserves, wetland and fishery sanctuaries, and ecologically critical areas. Despite this situation, people living in and around these ecosystems continue to extract and use the shrinking resources, mainly because they have few alternatives

Balancing conservation of wetlands and sustainability of local livelihoods

The Stung Treng Ramsar Site in Cambodia is arguably the most important wetland complex for biodiversity in the Mekong River Basin. Placed onto the List of Wetlands of International Importance (also called ‘Ramsar Sites’) in 1999, this section of the Mekong is home to a unique riparian forest that provides key habitat and food sources for a wide range of mammals, birds and fish. Yet despite this richness of biodiversity, there is widespread poverty and endemic food insecurity in the area.
