The Agricultural Sector has the highest share in creating the water crisis in Iran; therefore managing optimal use of water resources is inevitable. The purpose of this study is to investigate educational- extension strategies for optimal water consumption management to deal with drought in Dorroh section. This research was conducted by survey method and the data were collected using a question...
Agriculture on the American Great Plains has been constrained by historical water scarcity. After World War II, technological improvements made groundwater from the Ogallala aquifer available for irrigation. Comparing counties over the Ogallala with nearby similar counties, groundwater access increased irrigation intensity and initially reduced the impact of droughts. Over time, land-use adjust...
Climate change projections show that periods of droughts are likely to increase, causing decreasing water availability, salinization, and consequently farm income loss in the south-west Netherlands. Adaptation is the key to decrease a farmer’s drought vulnerability and to secure the agricultural sector’s performance at the aggregate level. Possible adaptation strategies include responses at the...
The Ningxia Hui Autonomous Region (NX region) of Northwestern China is threatened by increased meteorological drought induced by climate change (CC) and constraints on water supply from the Yellow River. Thus, the NX region is representative of attempts to adapt to CC and variability in China’s arid regions. Field visits, a questionnaire and in situ inspections were conducted in 2012–2014 to un...
RESEARCH DROUGHT-TOLERANT VARIETIES: Research on cassava’s water conserving properties and drought tolerance may lead to better varieties for farmers. USE FERTILIZER: Manure and synthetic fertilizer can improve soil fertility, but use must be integrated with other crops in the SHORT SHELF LIFE: Without proper storage or processing, cassava begins to deteriorate in as little as two to three days...
Drought is among the most costly weather-related events and Iran is highly vulnerable to the economic, social and environmental impacts of drought In this study expected profit maximization model and utility efficient programming were applied to determine optimal crop pattern, expected gross margin and water use with and without, drought condition at representative farms of homogenous groups. T...
Drought is a one of the most important natural disasters that have high socio-economic and environmental impacts. However, drought is more than a physical phenomenon or natural event. Its impact results from the relation between a natural event and demands on the water supply, and it is often exacerbated by human activities. The traditional approach to drought management has been reactive, re...
Drought, which is one of the most complexes hazards, is a temporary, recurring meteorological event, originates in the lack of precipitation and is a typical feature of any climate. The psychological and environmental impacts, consequential economy, and personal hardship experienced following droughts in both developing and developed countries have revealed the vulnerability of all societies to...
Climate change is increasing water scarcity in Sri Lanka. Whether these changes will undermine national-level food security depends upon the ability of the small-scale farmers that dominate rice production and the institutions that support them to overcome the challenges presented by changing water availability. Analyzing household survey data, this research identifies household, institutional,...
Grapevines are crops of global economic importance that will face increasing drought stress because many varieties are described as highly sensitive to hydraulic failure as frequency and intensity of summer drought increase. We developed and used novel approaches to define water stress thresholds for preventing hydraulic failure, which were compared to the drought stress experienced over a deca...
