It is widely recognized that food consumption patterns significantly impact water requirements. The aim of this paper is to quantify how food consumption patterns influence water requirements in China. The findings show that per capita water requirement for food (CWRF) has increased from 255 m3 cap−1y−1 in 1961 to 860 m3 cap−1 y−1 in 2003, largely due to an increase in the consumption of animal...
This research was conducted to develop relationships among evapotranspiration (ET), percolation (PERC), groundwater discharge to the stream (GWQ), and water table fluctuations through a modeling approach. The Soil and Water Assessment Tool (SWAT) hydrologic and crop models were applied in the Big Sunflower River watershed (BSRW; 7660 km(2) ) within the Yazoo River Basin of the Lower Mississippi...
Three rounds of pulse polio immunization in January, February and March, 2007 were evaluated in Valsad and Vapi cities. Randomly selected team members of 50% booths and teams working during house to house activity were interviewed. Approximately 80% of eligible children were immunized on booths whereas remaining eligible were covered during house to house activity. In February, 2007 round, mOPV...
Characterizing precipitation seasonality and variability in the face of future uncertainty is important for a well-informed climate change adaptation strategy. Using the Colwell index of predictability and monthly normalized precipitation data from the Coupled Model Intercomparison Project Phase 5 (CMIP5) multi-model ensembles, this study identifies spatial hotspots of changes in precipitation ...
Increased water scarcity implies that residents of arid, heavily populated regions of the U.S. will have to increase water conservation or else face the consequence of water shortfalls. Voluntarily conserved water is an impure public good since it is non-excludable and rival in consumption. This means that water conservation benefits are subject to free-riding behavior. This paper considers a d...
A successful programme is reported from Mozambique for training middle-level health workers to perform fairly advanced surgical procedures in remote areas where the services of consultants are virtually unobtainable. Manpower and financial constraints obliged Mozambique to train medical assistants to perform surgical work in rural areas, where three broad priorities were identified: pregnancy-r...
In this paper we study the simultaneous problems of food waste and hunger in the context of food (waste) rescue and redistribution as a means for mitigating hunger. To this end, we develop an empirical model that can be used in Monte Carlo simulations to study the dynamics of the underlying problem. Our model's parameters are derived from a data set provided by a large food bank and food rescue...
[1] During the last decade, there have been increasing concerns over water resource drought in northern England, brought about by the 1995 Yorkshire drought with an estimated 5-month rainfall return period of 200 years. The impacts of climatic change and variability on water resource reliability, resilience, and vulnerability in this region are examined by modeling changes to weather type frequ...
In Japan, the interest in IT education is continuously growing. Most goals of the IT education involve metaability, which cannot be learned by the traditional Japanese instructional methods. It is difficult to design effective IT education material. Moreover, there are only a few specialists in IT education. For this reason, it is necessary and important to provide IT instructors with a powerfu...
