Article history: Received 13 October 2005 Received in revised form 17 April 2006 Accepted 26 May 2006 Available online 17 August 2006 In an effort to prioritize conservation efforts, scientists have developed the concept of biodiversity hotspots. Since most hotspots occur in countries where poverty is widespread, the success of conservation efforts depends upon the recognition that poverty can ...
It has been proposed that we are now living in a new geological epoch known as the Anthropocene, which is specifically defined by the impacts that humans are having on the Earth's biological diversity and geology. Although the proposal of this term was borne out of an acknowledgement of the negative changes we are imparting on the globe (e.g. climate change, pollution, coastal erosion, species ...
One of the greatest challenges in biodiversity conservation today is how to facilitate protection of species that are highly valued at a global scale but have little or even negative value at a local scale. Imperiled species such as large predators can impose significant economic costs at a local level, often in poverty-stricken rural areas where households are least able to tolerate such costs...
Biodiversity conservation on private land of the developed world faces several challenges. The costs of land are often high, and the attitudes of landowners towards conservation are variable. Scientists and practitioners need to scan for and adopt cost-effective solutions that allow for the long-term sustainability of conservation measures on private land. In this study, we focus on one of such...
It is internationally recognized that conservation policies should respect indigenous cultures and consider the livelihoods of people affected by conservation restrictions. Countering this are concerns that human occupation and use of natural reserves is incompatible with conservation aims. But in China today the continued use and management of natural areas by local communities is likely to de...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
Basic infrastructure like Power and Water production has come into focus due to the rapid growth witnessed in the Middle East. Hybrid desalination plants have high flexibility and play a vital role in water and power production. Conservation of fuel resources in the existing scenario of increasing fuel prices make it necessary to produce power and water in a cost optimal way. The challenge in o...
We provide error analyses for explicit, implicit, and semi-implicit monotone finitedifference schemes on uniform meshes with nonlocal numerical fluxes. We are motivated by finite-difference discretizations of certain long-wave (Sobolev) regularizations of the conservation laws that explicitly add a dispersive term as well as a nonlinear dissipative term. We also develop certain relationships be...
Where conservation resources are limited and conservation targets are diverse, robust yet flexible priority-setting frameworks are vital. Priority-setting is especially important for geographically widespread species with distinct populations subject to multiple threats that operate on different spatial and temporal scales. Marine turtles are widely distributed and exhibit intra-specific variat...
While terrestrial parks and reserves have existed in Tanzania since colonial times, marine protected areas are a much newer endeavor in natural resource conservation. As the importance of marine conservation came to the international forefront in the 1990s, Tanzania experienced a rapid establishment and expansion of marine parks and protected areas. These efforts were indeed crucial to protecti...
