Biodiversity ,Environment and climate change management
The threat of global climate change has caused concern among scientists because crop production could be severely affected by changes in key climatic variables that could compromise food security both globally and locally.
The focus of the great majority of climate change impact studies is on changes in mean climate. In terms of climate model output, these changes are more robust than changes in climate variability. By concentrating on changes in climate means, the full impacts of climate change on biological and human systems are probably being seriously underestimated.
Traditional knowledge’ gained political space in international environmental policy up until the early 1990s as a result of three areas of growing concern: environmental sustainability, indigenous peoples’ rights and the commercial potential of traditional knowledge.
While the TKRC, as Oguamanam has observed, has vastly improved the scope and depth of the IPC, one can argue that classifications abstracted from context can result in a demeaning of practices, to a lessening of its aura and a negation of its meanings and aesthetics.
Livestock systems in developing countries are characterised by rapid change, driven by factors such as population growth, increases in the demand for livestock products as incomes rise, and urbanisation. Climate change is adding to the considerable development challenges posed by these drivers of change.
Vegetation changes due to climate and human impact in Sahelian countries are rarely documented at species composition level[ The decrease or disappearance of certain plant species reduces vegetation cover and enhances the exposure of soil surfaces to wind and water erosion leading to increased land degradation[ Men and women in Niger were asked to note plant species and relate their numerical d
Public understandings and perceptions of, as well as engagement with, climate change have garnered the interest of research and policy for almost three decades. A portion of this growing body of literature examines such perceptions in-depth, using largely qualitative methodologies, such as personal interviews, limited sample size surveys, focus groups, and case studies.
Our study links environmental impacts of climate change to major socio-economic and agricultural developments in North Africa. We jointly investigate climate projections, vulnerability, impacts, and options for adaptation. Precipitation in North Africa is likely to decrease between 10 and 20%, while temperatures are likely to rise between 2 and 3 ◦C by 2050.
