In this study,we develop a suite ofmethods to evaluate the combination of Landsat-8, ALOS PALSAR, and SRTM data for mapping spatial distribu...

macroeconomic policies lead to changes in farming system. these changes are accompanied by some most prominent factors that affect soil erosion. change in relative prices and its impact on soil erosion, via induced changes in crop patterns and agricultural practices, are related to policies implemented. one of the major goals of the present study is to emphasize on the flow of trade policies in...

Mangrove forests, though essentially common and wide-spread, are highly threatened. Local societies along with their knowledge about the mangrove also are endangered, while they are still underrepresented as scientific research topics. With the present study we document local utilization patterns, and perception of ecosystem change. We illustrate how information generated by ethnobiological res...

295 Semi dry rice refers to rice which is sown on dry seed bed as an upland crop taking advantage of monsoon rains. At fourth or fifth leaf stage, when the rainfall intensifies or sufficient water is released from the tank or irrigation projects, the field is converted to wet land rice. The major barrier in improving the productivity of rice in this system is inefficient use of important plant ...

T 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. The remarkable degree of public awareness and support has been manifested in benefit rock c...

Introduction Mangrove forests are productive ecosystems found along the coastal zones of Brazil, providing several profitable resources such as timber, medicinal products, natural dye, fish, crustaceans, and molluscs. For the littoral dwellers of Northeast Brazil, the Brachyura crabs are a major economic resource. The main species they commercialize are the 'goiamum' (Cardisoma guanhumi), 'siri...

The main objective of this work is to determine the landscape planning alternatives populations that have a direct relationship with mangrove ecosystems (Bunche community). theoretical foundation Geo-ecology landscapes (GEL). phases were fulfilled are: i) characterization physical and natural landscape; ii) socio-cultural by participatory techniques, secondary information. techniques were: Work...

in recent years, mangrove forests with the high economical and environmental value are threatened with extinction by human activities. ex-situ conservation is an appropriate method to conservation this forest. this study was conducted with the purpose of studying the role of climatology factors as one of the most important environmental parameters in dispersion of mangrove forests of hormozgan ...

Royal mangrove wetland, Jamaica.” Journal of Coastal Research 14(3): 951-959. Studies on the historical development of mangrove wetlands are rare in contrast to the vast array of information on the geological development of these systems. Historical development of the Port Royal mangal was investigated so as improve understanding of recent changes occurring in relation to the increasing threat ...
