High yielding crop production technologies became available for farmers in irrigated favorable agricultural ecosystems from 1960’s known as Green Revolution, while 77% of world arable land (~1,086Mha in 2014, FAOSTAT) is estimated without irrigation and prone to water shortage or drought (a disaster from a shortage of rainfall and available water on agriculture and other human lives). Greater d...
Water is vital to food production: every calorie of plant food requires at least one litre of water, while one calorie of meat or dairy product can require up to 10 litres of water. Water is supplied either through rainfall or through irrigation. Irrigated agriculture uses 18 per cent of agricultural land, and produces 40 per cent of agricultural products. But urbanisation, agricultural land de...
in this research the focus of the researcher is on the influence of american myths that have long been held and offered by the american culture and ideologies. sam shepard is conceived to be one of the greatest playwrights of the contemporary american theater. in his works he depicts broken characters who are struggling to keep up with the national expectations but are ceaselessly borne back to...
Stable modeling in water resources management requires recognizing the relations between the different uses of water and their long-term results on one hand and taking into account the current and future access to water resources and demands for them, on the other hand. In recent years, Hamedan-Bahar plain has been identified as one of the restricted groundwater areas in Hamedan province. In t...
L ong spared the persistent droughts that have plagued the western United States this century, the Southeast suddenly finds itself the most rain-starved region of the country. In the face of this threat, policy makers and utility companies are struggling to identify sensible, sustainable options for managing the region's water. Although there currently is no immediate public health threat posed...
INTRODUCTION Wheat farmers in Virginia and southeastern US could benefit greatly from the availability of a shortduration summer crop that could be produced during the period between wheat harvest in middle of June and before planting of the next wheat crop during October. Some wheat farmers plant soybean as a double crop system, but the productivity of double-cropped soybean is extremely low a...
rain-water-harvesting is one of the means by which agricultural production can be increased to meet the growing food demands in all regions. the study indentified the factor affecting rain-water-harvesting technology adoption for irrigation and farmers practice in water harvesting against drought in lowland woreda, eastern hararghe, oromia region. both primary and secondary data were collected ...
Drought is one of the most threatened natural vulnerabilities that are initiated by reason of scarcity of rain in a specific region. By comparing with all other natural hazards, it is very tough to discover since it develops slowly and have massive effect on the society and environment. Hence, in many countries satellite based drought indications have been recommended for early identification. ...
We explore the unsustainable path that the Ogallala region faces, and provide some suggestions for policies that would extend the usable lifespan of the water in the aquifer, which supports the vast majority of the economy across this region. We emphasize the critical role of science as a foundation for policies that can help mitigate the disaster that is occurring across the region and provide...
BACKGROUND Rice (Oryza sativa L.) is a highly drought sensitive crop, and most semi dwarf rice varieties suffer severe yield losses from reproductive stage drought stress. The genetic complexity of drought tolerance has deterred the identification of agronomically relevant quantitative trait loci (QTL) that can be deployed to improve rice yield under drought in rice. Convergent evidence from ph...
