The aim of this study is to assess biogas production sustainability and environmental consequences in Brong Ahafo Region in Ghana. The study was carried out into three steps ,the qualitative, the quantitative and the modelling the biogas potential in the region, for the qualitative analysis; the administering of questionnaires randomly to the people of Brong Ahafo and the survey on biogas the quantitative analysis was carried out at laboratory scales through anaerobic fermentation using the fresh cow dung as the base for each substrate in four separate bio-digesters comprising of cowdung ,saw dust, food waste and coconut husk under the temperature between 26 – 37 °C, the pH range of 4.47-7.25 and the methane content 53-62 (%) for the period of eight weeks under suitable indicators. Modelling using the Renewable Energy technology screen and the Long Range Energy Alternative Planning (LEAP) Software From this study, the generation of gas from biomass has simply been as a by-product of anaerobic digestion of organic waste There are various types of biomass resources including organic waste and inorganic waste in the city of Brong Ahafo which are very suitable and have the potential for use as feedstock for biogas production to reduce the over reliance on wood fuel and fossil fuel, and by reducing it, would reduce climate change. The techno economic feasibility was carried out using the fixed dome digester of 6000 liters with an economic cost of four thousand two hundred dollars ($4,200) with an annual production cost of one hundred and forty dollars ($140). It’s payback time is in 3.9 months and a life time of 10 years using the RETScreen Software. This thesis helps to verify the availability of biomass in Brong Ahafo, the feasibility and economic importance of the technology and develop policy framework to enhance biogas uptake using Leap software. It also presents the potential benefits towards the environment by mitigating Greenhouse Gases.

Many studies have shown that the global warming leads to changes in climate system. These fossil fuels are mainly used for energy production. Energy availability is very crucial for socio-economic development. However, Burkina Faso, as many other countries in African Sahel suffers from a lack of energy. The main sources of energy in the country are the thermal power plants and some hydropower stations. Nonetheless, the electricity production is insufficient to meet the energy demand. So, one of the solution to reduce the unmet demand in energy is the use of renewable energy, especially wind energy. Using the Local Polynomial Interpolation for wind speed and based on Weighted Linear Combination (WLC) and Boolean logic with socio-economic criteria, the suitability windfarm lands for the Burkina Faso have been made with ArcGIS. In additional, the fuzzy membership were used to standardize the criteria. And the Analytic Hierarchy Process (AHP) method were used to weight each criteria as well. Finally, the Western part of the country presents a suitability windfarm land. This region occupies an area of about 10,197.39 km2 and represents 3.68% of the country. The potential area could generate an annual average wind power density in the range of 344-487 W/m2.

Biogas has been earmarked as one possible alternative, mainly in light of the problems with waste management. This study therefore aims to explore how Assess biogas production sustainability and environmental consequences. The assessment is empirically illustrated with a qualitative and quantitative case study based on Brong Ahafo region, with input from documents, interviews, observations and experimentation. This paper finds that in Brong Ahafo region the various biomass resource abound and easily available are animal manure, municipal waste, and agricultural residues. Biogas production in Brong Ahafo is highly sustainable due to the greater availability of biomass resources. The use of biogas in the studied areas, in place of wood for energy potentially saves seventy two thousand, eight hundred and ninety seven (72,897) tonnes of CO2 per year from being released into the atmosphere. This 72,897 tCO2 emission reduction is equivalent to 14,820 cars and light trucks not used.

The availability of water in the water basin is useful for irrigation, power generation, and livestock and for domestic use. This study, firstly evaluates the land use land cover change over the Black Volta basin for the years 1986, 2000 and 2014 using Landsat data, and analyzes historic observed rainfall, stream flow and temperature variability for 1982-2011. It also assesses the potential impact of land use land cover change on stream flow at Bui station. Using the Water Evaluation and Planning (WEAP) system model, it evaluates the potential effects of land use land cover change combined with climate change on the Bui dam area under four different scenarios. The study has shown that the land use and land cover has changed faster in Black Volta basin due to increase in population growth rate which impacted the Bui streamflow. It was found out that the stream flow varied much more than the rainfall, annually, periodically, seasonally and monthly except for the dry season, this is due to land cover and land use change in the basin. For the period of 1986 -2000, the land use has increased by 12.7% and the rainfall has increased by 14% while the stream flow has increased by 44%. However, for the period 2000-2014, the land use has increased by 59.9% and the streamflow has increased by 67% despite the decrease in rainfall about 0.16%. Therefore, the change in land use has changed the Bui stream flow dynamic and this change led to increase the stream flow and may favor Bui hydropower production. Moreover, it is observed that rainfall and streamflow variability follow the same pattern. In one hand, the climate change alone is promised to decrease the Bui power production under any changing climatic condition for the projected period 2012 to 2040. The land use land cover change is promised to reduce the negative effect of climate change on the Bui Hydro power production. Climate change under current condition is promised to decrease the energy production by 23.2% with No LCC while with LCC it will decrease by 2%. Climate change under dry condition is promised to decrease the energy production by 54% with No LCC while with LCC it will decrease by 46%. Climate change under wet condition promised to decrease the energy production by 0.15% with No LCC while with LCC it will increase by 40%. Therefore the LULCC under climate change condition is promised to favor the Bui hydropower production, but the main problem with LULCC is that it leads to soil erosion and sedimentation which can lead to siltation of the Bui reservoir and can damage the Bui hydropower turbine respectively.
