water stress, desertification, , erosion leading loss of arable land. agricultural practices use bulk of earth’s fresh water – 70 percent – , numbers predicted rise 50-100 percent 2025’. countries being forced divert more water ever before irrigate land. hydroelectric dams , mega-canal projects becoming new standard countries egypt can no longer depend on rainfall or natural flood cycles. these water shortages causing source of conflict between neighboring nations live increasingly high levels of water scarcity. policy responses these events implemented in order strengthen socio-economic growth, human health statuses, , environmental sustainability of these areas. combining current limitations water , transitions practices such agroforestry , shifting cultivation makes land susceptible aeolian erosion weakening soil composition , exposing larger areas of land destructive wind. aeolian erosion largely effects deserted areas, reducing air quality, polluting water sources, , limiting fertility of nearby land.

climate change creating more extreme weather patterns, , agricultural practices estimated cause 10 12 percent of greenhouses gas emissions. warming increase mentioned rates of desertification , insect activity , agricultural zones near equator may lost. however, due uneven warming occur, higher latitudes expected warm @ faster rates other areas of globe. scientists presenting idea areas in canada , siberia may become suitable farming @ industrial scale, , areas able account farmland lost @ equator. conservative estimates place shift of traditional crops (maize, grain, potatoes) northward @ 50 70 kilometers decade. believed non-traditional crops (berries, sunflowers, melons) established on southern sides of these countries. changes in climate may force humans adapt, adopt new practices, , alter old habits promote success in uncertain age of climate change ahead.
