Agricultural practices already exist that have the potential to be "climate-smart" if applied in the appropriate context to fit climatic natural resources and socio-economic circumstances.
Opportunities for diversification of sisal production with other crops are limited or non-existing owing to environmental, climatic and resource constraints.
In the present era of climatic variability, resource scarcity and fast-growing population, it is necessary to enhance productivity as well as sustainability of agriculture for circumventing the global food insecurity.
Modern-day cultures and policy makers need to pay attention to "deep time," or the very slow changes that accompany the deterioration of climatic conditions and resources, for the benefit of third, fourth or fifth generations, Dr. Giosan said.
A geographer whose research interests focus on the human aspects of environmental change at local, national and global scales, de Sherbinin is lead author of articles appearing in Annual Reviews of Environment and Resources, Climatic Change, Environmental Research Letters, Global Environmental Change, Science, and Scientific American.
In general, by weakening the productivity and functioning of livelihood resources, climatic stresses aggravate the vulnerability of households dependent on these resources.
Environmental variability in terms of climatic factors, social resources, grazing by herbivores and human interference are the critical factors which regulate the spatial and temporal patterns of the vegetation of an ecosystem (Chapin et al. 1993).
The origin of its settlement appears connected with Holocene climatic ameliorations (aquatic resources) that started ~10,000 years before present (YBP).
As a result, critical features of the newly occupied habitat such as climatic conditions, food resources, and important competitors may be very similar to or different from the historic range.
