“…The daily use of reservoir water for power generation results in large fluctuation of the water level (between 53 -80 m) and area of the water (between 65-220 ha) in the reservoir. Such daily and seasonal water uses and water level fluctuations depend on the hydroelectric power demand of the country, higher during high demand season (summer) and time of the day (evening) [4] [8].…”

Spatial and temporal variation in planktons and water quality parameters were investigated in order to determine the effects of seasonal water use on reservoir water quality and planktons' diversity in Kulekhani Multipurpose Reservoir, Nepal. This study also focuses on interactions among various water quality parameters with planktons and how such interactions can affect the second major utility, the fish farming in the reservoir. The analyses of seasonal water samples collected from three different sampling locations in the reservoir showed that select water quality parameters varied significantly (P < 0.05) with sampling seasons (transparency: 30 -250 cm, pH: 7 -7.5, alkalinity: 30 -120 mg/L, DO: 6 -11.5 mg/L, CO 2 : 0.1 -1.1 mg/L) and sampling locations (phosphate: 0.1 -0.25 mg/L, nitrate 0.01 -0.19 mg/L) in the reservoir. Three groups of zooplankton and four classes of phytoplankton, respectively with eleven and twelve genera, were identified and quantified in the reservoir.Among them, Cyclops, Asplanchana, and Keratella were most dominant zooplanktons while Synedra, Melosira and Peridinum were the most dominant phytoplankton in the reservoir water. The abundance of select zooplanktons (Cyclops, Keratella, Polyanthra), and phytoplankton (Navicula, Melosira, Amphora, Chroococcus, Staurastrum, Scendesmus) showed significant interaction between sampling sites and sampling seasons, while the other varied only with sampling seasons and/or sites. These results showed that seasonal water level fluctuations, along with the variation of water quality para- meters, change the abundance and diversity of planktons' in the reservoir. Such changes can negatively impact the fish in cage culture, affecting the livelihood of people extensively relying on these fish farming.

“…5 The selection was done with a consultation of the local residents to ensure that influential educational institutions and public centers have been covered. 6 A technical discussion on electricity shortage in Nepal and the reasons behind it can be found in Sharma and Awal (2013). 7 As told by a local teacher in a recent telephone conversation with the author, the school has now gathered some laptops and set-up solar power panels from the financial support of the local community…”

The relation between Internet and development rests on the preconditions of minimum access, quality, affordability and many more. Presenting the picture of access, quality, and affordability, we raise doubts that Nepali internet infrastructure in its present form has any contribution to economic development. The Nepali policy circle also has felt the necessity of proliferating Internet access and use. But we argue major targets of the Nepali ICT policies are detached from the reality and hence failure prone. The formulation of a robust ICT policy cannot bypass the analyses of actualities of the demand side. There is a dearth of detailed statistics of ICT access, use, and affordability in Nepal. We thus recommend the government should conduct a census of ICT access, use, and affordability that would help the formulation of more grounded policies.

“…Nepal has hydro potential of 83,000 MW (Shrestha, 1966). Steep mountainous terrain and continuous flow in more than 6000 rivers/rivulets makes hydropower widely available throughout the hilly region of Nepal (Sharma & Awal, 2013).…”

Abstract:Millions of Nepali inhabit in a far-flung hamlet of Nepal, where the extension of national grid is unlikely even in the new future. Isolated Micro-hydro power plants are extensively used in these areas. This paper addresses the problem of deficient electricity during peak period in existing conventional micro-hydro plants by the introduction of battery storage in the plant. Micro-hydro plant with battery bank storages surplus power, which would be wasted in case of conventional micro-hydro plant, during off-peak period and supplies during peak period. The control strategies for Electronic Load Controller (ELC), three -phase ac/dc converter and buck converter are realized in Matlab Simulink environment. The simulated system was able to store surplus power into battery bank when load demand was less than power generated by Synchronous Generator (SG) and supply when the load demand was higher than generator's generation. This model can be implemented in the already existing micro-hydro plants where the load demand for a short time has increased beyond generation capacity of generator.
