We eat more shrimp than any other kind of seafood, and, for many of us, it's the only seafood we consume. But, while we might not pay much for our shrimp, recent reports have shown it comes at enormous cost. The same farms that make bottomless shrimp baskets possible are also responsible for the devastation of ecosystems that are important for the entire globe, and the industry as a whole is rife with human rights abuses, like slavery, child labor, and murder. Depending on whom you ask, Jean Claude Frajmund is either the guy who's going to bring about a radical shift in shrimp farming or the latest in a long line of naively ambitious aquaculturists. Relatively few people have heard about the issues with shrimp, or thought about seeking a sustainable alternative.

Mangrove forest decline: consequences for livelihoods and environment in South Sulawesi

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. Mangroves are salt-tolerant trees, also called halophytes , and are adapted to life in harsh coastal conditions. They contain a complex salt filtration system and complex root system to cope with salt water immersion and wave action. They are adapted to the low oxygen conditions of waterlogged mud. The mangrove biome , or mangal, is a distinct saline woodland or shrubland habitat characterized by depositional coastal environments, where fine sediments often with high organic content collect in areas protected from high-energy wave action. The term " mangrove " comes to English from Spanish perhaps by way of Portuguese , and is likely to originate from Guarani.

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. While the network of paved highways is relatively reduced in extension, preventive measures are urgently required to impede any major shift in the current scenario, caused by the expansion of major development programs.

Jennifer L. Bowen and Joanna K. Ivan Valiela, Jennifer L. Bowen, Joanna K. The mass media and scientific press have widely reported losses of tropical environments, such as felling of rain forests and bleaching of coral reefs. This well-merited attention has created a worldwide constituency that supports conservation and restoration efforts in both of these threatened ecosystems.

Mangrove forests capture and store exceptionally large amounts of carbon and are increasingly recognised as an important ecosystem for carbon sequestration.

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.

Mangrove forest decline: consequences for livelihoods and environment in South Sulawesi

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.

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. This paper investigates how common property institutional arrangements contribute to sustainable mangrove fisheries in coastal Ecuador, focusing on the fishery for the mangrove cockle Anadara tuberculosa and A. Findings from interviews with shell collectors and analysis of catch-per-unit-effort CPUE indicate that mangrove concessions as common property regimes promote community empowerment, local autonomy over resources, mangrove conservation and recovery, higher cockle catch shares, and larger shell sizes, but the benefits are not evenly distributed. Implications for coastal and fishery management are discussed in the conclusions.
