Abstract Large carnivores such as the jaguar Panthera onca are particularly susceptible to population decline and local extinction a result of habitat loss. Here we report on long-term monitoring in mixed land-use area eastern lowlands Bolivia from March 2017 December 2019. We recorded 15 individuals four reproduction events (five offspring three females), suggesting that our study harbours res...

Sitting in our offices early in the morning of September 11, 2001, we, like many across the world, watched with incredulity the twin terrorist strikes on the World Trade Centre. Riveted to the television screen, we witnessed the beginnings of a nightmare whose images will likely remain with us for a long time.

nowadays because of various factors, including inappropriate land use, and indiscriminate exploitation of water resources, soil and vegetation, wide areas of the country were exposed to destruction of lands and desertification. therefore dealing with this situation requires a comprehensive land use program (water and land) and appropriate environment potency. the study area is patom district of...

Kabale is a mountainous district In this paper, a review is made of land degradation within the district Land degradation is due to population pressure on the land and poor traditional land use practices. Introduction Mountain environments are very fragile and delicate ecosystems. Intensification of land use caused by an increase in population can have profound effects on the system by disturbi...

     Reduction of water resources limits the ability of farmers for food production and subsistence. Nowadays the quick growth of population has been the most important factor in the decline of renewable water. In many parts of Iran, including region of interest, the major factor in water resources decline was land use change, that may  cause to ecological destruction and disruption. Sustainabl...

With the rapid advances in sensors of remote sensing satellites, a large number of high-resolution images (HRIs) can be accessed every day. Land use classification using high-resolution images has become increasingly important as it can help to overcome the problems of haphazard, deteriorating environmental quality, loss of prime agricultural lands, and destruction of important wetlands, and so...
