climate is changing and various scenarios indicate accelerated climate change in the future. if farmers and rural residents’ capacities do not enhance to adapt to the impacts of climate change, the impacts will overwhelm on agriculture and rural communities. extension systems can play an important role in agricultural adaptation to climate change. therefore, the aim of this research was to expl...
any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Climate change is one of the most serious challenges confronting agriculture, particularly, in rural Nigeria. This study examined the perception, adaptation strategies and challenges of climate change among rural households in Kogi State, Nigeria. A two stage sampling techniques was used in the study. The first stage involves the purposive selection of six (6) rural farming communities, followe...
Climate change will have far-reaching implications for Inuit health. Focusing on adaptation offers a proactive approach for managing climate-related health risks-one that views Inuit populations as active agents in planning and responding at household, community, and regional levels. Adaptation can direct attention to the root causes of climate vulnerability and emphasize the importance of trad...

introduction agriculture is the most important sector of the economy in iran and it is highly dependent on the climate. the impact of global climatic change on agriculture has recently become an issue of increasing importance. the global climate change has been drawing attention of many to this very important topic of climate change, though it was a difficult proposition for many to accept whet...
Climate change adaptation is generally defined as adjustments in natural or human systems in response to actual or expected climate stimuli or their effects which moderated harm or exploit opportunities (IPCC, 2007: 869). Agricultural entrepreneurship is identification process of opportunities and threads of activity environment with new policies to create transformation in agriculture. Therefo...
Our scientific view on climate change adaptation (CCA) is unsatisfying in many ways: It is often dominated by a modernistic perspective of planned pro-active adaptation, with a selective focus on measures directly responding to climate change impacts and thus it is far from real-life conditions of those who are actually affected by climate change. Farmers have to simultaneously adapt to multipl...
