Mixed crop-livestock systems provide livelihoods for a billion people and produce half the world’s cereal and around a third of its beef and milk. Market orientation and strong and growing demand for food provide powerful incentives for sustainable intensification of both crop and livestock enterprises in smallholders’ mixed systems in Africa. Better exploitation of the mutually reinforcing nat...

While the IPCC will continue to lead Earth System projections for global issues such as greenhouse gas levels and global temperature increase, high-resolution regional Earth System predictions will be crucial for producing effective decisionmaking tools for day-to-day, sustainable Earth System management and adaptive management of resources. Regional Earth System predictions and projections at ...

Stock assessment of Otolithes ruber was carried out using Virtual Population Analysis (VPA) method in the coastal waters of Northwest Persian Gulf. Catch and length frequency data during 2002-2012 were converted to age frequency. The maximum of stock number and biomass were observed in age group 1 and 2 respectively. The minimum of stock number and biomass were observed age group 6. The maximum...

Regional sustainability encourages a re-examination of development programs in the context of environmental, social and economic policies and practices. However, sustainability remains a broadly defined concept that has been applied to mean everything from environmental protection, social cohesion, economic growth, neighborhood design, alternative energy, and green building design.

Furthermore, animals ...

The hue and cry about the stark despoliation of the Niger Delta has been ongoing; and the issues at stake have centered mostly on the gross and glaring underdevelopment in the area despite the vast resources that have accrued to the Nigerian state from the region. Perhaps the most disturbing, is that oil exploration and exploitation in the Niger Delta is carried out without regard to internatio...

Groundwater exploitation requires better understanding of the resource availability and quality/vulnerability. Geophysical techniques, pumping test, hydraulic measurement, borehole logging quality test analysis have been used in Ibulesoro, southwestern Nigeria, to hydrogeological system terms groundwater availability, aquifer delineation, evaluate physico-chemical biological contents. The study...

This essay constitutes a piece of boundary work between science and policy. It illustrates the conflicts, but also the opportunities, that natural resource management encounters in the twenty-first century. I have tried to provide a widely accessible document that argues why a more holistic approach to conservation and natural resource management is imperative. Inspired by the concept of “Integ...
