Accurate crop performance monitoring and production estimation are critical for timely assessment of the food balance of several countries in the world. Since 2001, the Famine Early Warning Systems Network (FEWS NET) has been monitoring crop performance and relative production using satellite-derived data and simulation models in Africa, Central America, and Afghanistan where ground-based monit...

The aim of this review is to present a holistic view on irrigation with respect local environmental and social conditions. Future development addressed focus sustainable development. However, technical aspects are included references provided for further reading completeness. An intervention always combination feasible technical, aspects. This provides an overview the various fields expertise i...

We developed an irrigation mapping methodology that relies on remotely sensed inputs from MODerate Resolution Imaging Spectroradiometer (MODIS) instrument, globally extensive ancillary sources of gridded climate and agricultural data and on an advanced image classification algorithm. In the first step, we used climate-based indices of surface moisture status and a map of cultivated lands to pro...

The impact of improved irrigation and nutrient practices on ground water quality was assessed at the Nebraska Management System Evaluation Area using ground water quality data collected from 16 depths at 31 strategically located multilevel samplers three times annually from 1991 to 1996. The site was sectioned into four 13.4-ha management fields: (i) a conventional furrow-irrigated corn (Zea ma...

This paper illustrates the malleable boundaries that define nature. Personal construct theory is employed to examine the apparent contradiction of the human/nature binary posed by landscapes generated by domesticated agriculture and physical and biological processes. Specifically, the paper reports on how tourists to the Kimberley region of Australia discriminate between their perception of hum...
