Abstract: Watershed development is an important component of rural development and natural resource management strategies in many countries. The study was conducted to investigate the current situation of Warja watershed for further improvements to promote Sustainable and productive livelihood through the integration of different watershed components in participatory approach. Household interview and biophysical resources assessment followed by watershed mapping techniques were used for the data collection. Purposive sampling methods were used to select 63 households and Warja watershed boundary was delineated and its map was developed based on the preliminary outlet identified with the help of GPS reading. Descriptive statistics and diversity indices were used for data analysis. The results of the study indicated that Agriculture was the principal occupation (98.4%) of the population of Warja watershed. The average farmland size was 1.9 hectares while 25% of the households have farmland ranging from 0.25 to 1 hectare. The minimum and maximum family size of the sample farm households was 2 and 16 respectively. The common types of off-farm income generating activities are petty trade and working as daily labor. Slope gradient of Warja watershed ranges from 0 to more than 30 and the slope gradient of 2-5 and 5-10 cover the greatest in area coverage representing 204ha and 145ha respectively. Soil laboratory analysis result showed that sandy loam was the major soil type of Warja watershed. Overall results concluded that land degradation and biodiversity loss were a serious concern and watershed management programs could be strengthened. Awareness creation and strengthening capacity of rural communities on integrating crops, livestock and natural resource management technologies for effective soil and water conservation measure should be enhanced through participatory integrated watershed management approach.

Abstract: The Energy management in Micro-Grid system is one of the most irrefutable issues in micro grid technology development. The Micro grid energy system consists on non-conventional resources, unit with storage energy and islanded or grid connected mode of operating loads. This tabloid presents a Micro-Grid energy management system for distributed generation connected MG with hybrid energy storage system. Hybrid energy storage system is achieved by combining the Ultra-capacitor and battery storage. The proposed energy management system in micro grid with hybrid energy storage system follows the two techniques, such as forecasting and optimization. Prediction of solar irradiance, load demand and temperature are coming under the Forecasting technique. For the economical operation in a grid connected micro grid the optimal day-ahead scheduling of power generation and load demand is performed by the optimization technique. The MG will absorb or deliver the prespecified amount of power. In this method MG connected to the power grid in large numbers are integrated. The main intension of the energy management system is power balancing in the micro grid. The MATLAB/Simulink environment has been used to analyzing the effect of Energy management in micro-gird with hybrid energy storage system. The simulation results will show the effective and stoutness of the proposed energy management method.

Abstract: Fuel cells offer a promising alternative to conventional fossil fuel power systems, due to their high efficiency, low environmental impact, and flexible application. Fuel cells are known for their reliability, power quality, eco-friendly nature, and fuel efficiency. Its promising power technology and extremely significant in the near future. One of the suggested power systems for residential, automotive, and portable applications is the Solid Oxide Fuel Cell (SOFC). Solid oxide fuel cell (SOFC) power devices are at the core of complex and efficient energy conversion systems for distributed power generation. Such power systems are currently in various stages of development. These power plants of the future feature complicated configurations, because of the fuel cell demands for a complex balance of plant. The purpose of this project is to review a Theoretical design of one type of fuel cell - Solid Oxide Fuel Cell (SOFC) - that can produce 1000 watt as electrical power. The type of Solid Oxide Fuel Cell (SOFC) is planar with anode supported that consists of electrolyte, cathode current collector, and anode supported. Fuel cells are attractive for several applications; however, there are several barriers that must be overcome before they can become an alternative to internal combustion engines.
