Scholars of common property resource theory CPR have long asserted that certain kinds of institutional arrangements based on collective action result in successful environmental stewardship, but feedback and the direct link between social and ecological systems remains poorly understood.
Preservation and recovery of mangrove ecosystem carbon stocks in abandoned shrimp ponds
Print This Page. At a. Tsunamis are shock waves that travel through the ocean at great speeds. When they hit low-lying coastal areas, they rise up as moving walls of water that break every thing apart when they make landfall and then drag everything out to sea when they retreat. It washed a town of 10, people and all its buildings into the sea.
The Shrimp Industry Is Dirty. Can New Farming Technology Clean It Up?
Mangrove forests in the tropics and subtropics grow in saline sediments in coastal and estuarine environments. Preservation of mangrove forests is important for many reasons, including the prevention of coastal erosion and seawater intrusion; the provision of spawning, nursery, and feeding grounds of diverse marine biota; and for direct use such as firewood, charcoal, and construction material —all of which benefit the sustainability of local communities. However, for many mangrove areas of the world, unsustainable resource utilization and the profit orientation of communities have often led to rapid and severe mangrove loss with serious consequences. The mangrove forests of the Takalar District, South Sulawesi, are studied here as a case area that has suffered from degradation and declining spatial extent during recent decades. On the basis of a post-classification comparison of change detection from satellite imagery and a survey of households, we provide an estimate of the mangrove change in the Takalar District during — and the consequences of those changes. Mangrove forest areas were reduced by The changes were caused mainly by the mangrove clearing and conversion to aquaculture, and consequences have been increasing forest degradation, coastal abrasion, seawater intrusion, a decline in fish capture, a reduction in juvenile shrimp and milkfish, and outbreaks of shrimp disease.
Replanted mangroves dot a shrimp pond in the Mekong Delta. At the southernmost tip of the Mekong Delta, Vietnamese shrimp farmers are going organic and restoring mangrove forests to help protect coastal communities against sea level rise. Mangroves provide a natural barrier against storms and flooding. They also provide habitat and support a wide variety of species, including endangered ones. Citing provincial data, a study by the Asian Development Bank ADB notes that about 66, hectares of mangroves have been converted to shrimp ponds from to Coastal erosion also destroyed some 3, hectares of mangroves from to The geographic and socioeconomic features of the Greater Mekong Subregion make it particularly vulnerable to climate change.
Mangroves play an essential ecological role in the maintenance of the coastal zone and are extremely important for the socioeconomics of coastal communities. However, mangrove ecosystems are impacted by a range of anthropogenic pressures, and the loss of this habitat can be attributed primarily to the human occupation of the coastal zone. In the present study, we analyzed the spatial patterns of land use in the mangrove of the Brazilian Amazon coast, and evaluated the anthropogenic drivers of this impact, using a remote sensing approach. We mapped the road network using RapidEye images, and human settlements using global data. The study also revealed that the paved road network is one of the principal drivers of land use in the mangrove, whereas other factors, such as population density, urban centers, and the number of settlements are much less important.
Mangrove Rehabilitation on Highly Eroded Coastal Shorelines at Samut Sakhon, Thailand

In an attempt to prevent coastal erosion, 14, Rhizophora mucronata RM trees were planted across a heavily eroded shoreline at Samut Sakhon, Thailand. The survival rate of RM was high at the landward area and decreased at the offshore area. The most landward plot showed the highest survival rate when measured 4 years after planting
A mangrove is a shrub or small tree that grows in coastal saline or brackish water. The term is also used for tropical coastal vegetation consisting of such species.
