(2009-08-03)
Shortage of drinking water is chronic, sever and widespread in Kutch - a hot and very arid region. It is specially acute in coastal villages where surface sources dry up rapidly and groundwater is not potable. Many of ...
Leveraged Innovation Management: Key Themes from the Journey of Dewrain Harvest Systems
(2009-08-13)
Systems for harvesting dew for human consumption are new to India. This paper provides insights from the tracking of the innovation journey of dewrain harvest systems from incidental observation to commercialization. It ...
Cropping in Arid Area Greenhouse
(2009-08-21)
In hot, arid regions, yields are low and unstable, growing season limited to one. Greenhouses can stabilize and improve yields and extend seasons. But their adoption is impeded by the requirement of large amount of water ...
Feasibility of integrating solar desalination
(2009-12-12)
In this paper, we examine via simulation, feasibility of using solar stills as partial source of water to irrigate crops inside polyhouses. Need to consider such a possibility arose in the course of our work in Kutch, a ...
Performance of Greenhouse Coupled to Earth-Tube-Heat-Exchanger in Closed-Loop Mode
(2009-09-05)
An experimental greenhouse coupled to an Earth Tube Heat Exchanger (ETHE) in closed-loop mode has been installed at Kothara (23o 40' N 72o 38' E), India. Area is hot and extremely arid. ETHE is used to warm the greenhouse ...
Fourier Representation of Climatic Data of Kothara-Kutch
(2009-09-02)
Fourier series representations of some climatic variables were developed using data from the site of an experimental greenhouse at Kothara (Kutch). Hourly data was averaged over a month to yield a profile of an ...
