The available agricultural technology will not be able to meet the challenge of the present population growth of about a billion additional mouths every 12–14 year without detriment to natural resources and the environment and has to be suitably modified.† The food on our planet could potentiallyRead MoreFocus On California And Drought1736 Words   |  7 Pagesprecipitation, may vary considerably spatially. This is a most often thought of as drought in comparison to precipitation, assessing the degree of dryness (in relation to a local or area average) and the duration of the dry period. A concern of farmers is agricultural drought when available water verkest 02 supplies are not able to meet crop water requirements. Which can occur for many reasons, like low precipitation, the timing of water is available, or decreased access to water suppliesRead MoreHow Does a Climate Change Influence Water Resources? Essay3137 Words   |  13 PagesHow does a climate change influence water resources? Climate change is the biggest challenge that we face in the world today. It is already leading to significant changes in the world’s physical environment. Extreme weather events are becoming more frequent. Glaciers are melting. Sea ice and snow cover are declining. Animals and plants are responding to earlier seasons. Global warming has already driven up mean sea levels by 110-20 centimetres during the last 100 years, and this is forecast toRead MoreClimate Change and Disaster Risk Reduction6524 Words   |  27 Pagesmeteorological conditions – wind, rain, snow, sunshine, temperature, etc. – at a particular time and place. By contrast, the term â€Å"climate† describes the overall long-term characteristics of the weather experienced at a place. For example, Singapore, in the tropics, has a hot wet climate, while continental Mongolia always has cold winters. The ecosystems, agriculture, livelihoods and settlements of a region are very dependent on its clim ate. The climate therefore can be thought of as a long-term summary of weather
