This book was released on 2016-12-31 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This case study describes the community of a small village called Ingotse in Kakamega county in western Kenya. Like most rural, food-insecure communities in sub-Saharan Africa, Ingotse village relied on rain-fed agriculture for production of staple crops. Farmers in this village raised some funds to sink a borehole. This was done in collaboration with a non-governmental organisation (NGO) known as Water for All which gave the community a solar-powered pump to distribute the water to the homesteads. Water from the borehole was used for irrigation, providing food crops all year round. Women and children no longer had to walk long distances to the river to fetch water; they had extra time in their day for other activities such as doing homework with children.

This book was released on 2006 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Food production is a problem in many of the regains in the world. Today, the process of producing food is very dependent on energy. The dependency on fossil fuels causes the cost of producing crops to increase as the prices of fuel increases. Using a renewable energy sources to power an irrigation system is a mean of decreasing the dependency of food products on the prices of fuel and minimize the impact of the irrigation system on the environment. A model was developed to simulate and predict the performance of an irrigation system powered by a renewable energy source. Both solar energy and wind energy were considered for the modeling of the system. The solar energy was simulated using the difference between the maximum and the minimum daily temperatures as an indicator of the amount of clouds in the atmosphere. The model is a modification of earlier models and has the advantage of not needing to be calibrated for each new site. Results showed that a model that calibrates it self for the upper and the lower expected values of the solar radiation can be developed using meteorological data such as the location of the site, the daily temperatures, and the minimum relative humidity. ii The wind energy was predicted using the power coefficient of the turbine and statistical representation of the daily wind speeds. The average hourly values of the wind speed were used for finding the distribution constants for the Weibull distribution and Rayleigh distribution. The results showed that the Weibull distribution is more accurate in predicting the expected power output of the turbine when the daily wind speed coefficient of variation (Cv) was less than 0.5. When the Cv is greater than 0.5 the Rayleigh distribution gives better results. A computer model was developed using Visual Basic to model the system and the resulting model was tested and used in comparing the economics of a traditional irrigation system and an irrigation system powered by solar panels. The system powered by the solar panel had a greater total annual cost than the traditional system but the sensitivity analysis performed showed that if the trends in energy prices continue and the prices of the solar panels continue to decrease, the cost for operating the traditional systems will be close to the cost of operating the systems powered by the solar panels in less than a 10 years.
Download or read book The Benefits and Risks of Solar Powered Irrigation a global overview written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2018-04-12 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report gives a state-of-the-art overview of policies, regulations and incentives for the sustainable use of solar-powered irrigation technologies (SPIS) around the world. SPIS offer a viable, low-tech energy solution for irrigated agriculture, providing a reliable source of energy in remote areas, contributing to rural electrification, reducing energy costs for irrigation and enabling low emission agriculture. Nevertheless, SPIS have a significant initial investment cost and require innovative financing models to overcome this barrier to adoption, especially for small-scale farmers. Technical knowledge and service infrastructure is needed to ensure that the systems run effectively. Moreover, SPIS – if not adequately managed - bear the risk of fostering unsustainable water use as lower energy costs may lead to over-abstraction of groundwater. This report looks at how different countries work to create an enabling environment for SPIS technologies, while managing the risks that come with it.

Download or read book Geothermal Wind and Solar Energy Applications in Agriculture and Aquaculture written by Jochen Bundschuh and published by CRC Press. This book was released on 2017-08-02 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: The agri-food chain consumes about one third of the world’s energy production with about 12% of it for crop production and nearly 80% for processing, distribution, retail, preparation and cooking. The agri-food chain also accounts for 80-90% of total global freshwater use where 70% alone is for irrigation. Additionally, on a global scale, freshwater production consumes nearly 15% of the entire energy production. It can therefore be argued that making agriculture and the agri-food supply chain independent from fossil fuel use has a huge potential to contribute to global food security and climate protection not only for the next decades but also for the coming century. Provision of secure, accessible and environmentally sustainable supplies of water, energy and food must thus be a priority. One of the major objectives of the world’s scientists, farmers, decisions makers and industrialists is to overcome the present dependence on fossil fuels in the agro-food sector. This dependency increases the volatility of food prices and affects economic access to sustenance. This book provides a critical review of recent developments in solar, wind and geothermal energy applications in agriculture and the agro-food sector such as processing, distribution, retail, preparation and cooking.
