Session 4
The first presenter for this session, Dr. Bertrand Tchanche from the International Institute for Science and Sustainable Development (IISSD), Amiens, France; presented on the “Interdisciplinary Approach to Accelerate Energy Access across Africa”. He holistically explained the disparities in energy resources at national and regional levels in Africa and the energy situation characterized by: a mismatch between the supply deficit and the surplus of untapped potential of renewable energies (wind, hydro, biomass, solar, geothermal); the polluting effects of fossil fuels (oil, coal and gas) on the environment and the impact on global warming; and the fact that energy was not taken into account as a fundamental and essential factor for sustainable development in political economy. He suggested an interdisciplinary methodology to put in conjunction with engineering and social sciences. This will help overcome barriers to energy access and contribute to sustainable development of communities through appropriate methods that facilitate the acceleration and adoption of renewable energy technologies. His method being also organizational seeks to foster collaboration between different actors and institutions (governments, organizations, communities) in order to implement a regulatory, legal and administrative framework that encourages investors and make reliable and affordable renewable energy technologies.
Thereafter came the second presenter, Jerome Ndam Mungwe, from Politecnico di Milano, Italy. The presentation titled was “Sustainable Energization of Rural Areas of Developing Countries. A comprehensive planning approach” highlighted that Access to modern energy and energy related services in developing countries is a double-faced challenge with 1.3 billion people unable to access electricity and 2.6 billion relying on traditional biomass for cooking. According to him, solutions to this challenge can neither be through the isolated promotion of individual technologies nor fuel switching, but rather through a systemic approach to a more comprehensive energy access strategy, with the supply of alternative energy carriers and planning of complete energy solutions via a more comprehensive and sustainable rural energy planning. He further explained that the current approaches to Sustainable Energization do not account for the current energy balance and have not been applied in the context of rural areas. In conclusion, he proposed a comprehensive seven step rural energy planning methodology for the sustainable energization of rural areas in developing countries, which takes into account the current energy balance and integrate energy drivers in the energy services supply network. The application of this approach in a rural context shows a great improvement in the quantity, quality, and variety of accessible and affordable energy services for a more sustainable development of rural areas.
The presenter that followed was, Prof Yekeen A. Sanusi, from the Federal University of Technology, Minna, Nigeria, in a presentation titled “Energy Poverty and its Spatial Differences in Nigeria: Reversing the Trend” who clearly pointed out that the high level of poverty in the developing countries is also manifested in energy. Using his home country as a case study, he said that despite the abundant natural resources in Nigeria, access to energy is very low; with attention only on hydro sources for electricity generation and other renewable energy sources attracting very little attention. He examined thoroughly, households’ access to energy, energy poverty, spatial disparity in energy poverty and established relationships between energy poverty and factors of energy access.
Finally, Yusto M. Yustas, from Sokoine University of Agriculture, Tanzania schooled the conference participants on “Characterisation of Renewable Energy Resources and Energy Demand in Semi-Arid Rural Areas”. He pointed out that the semi-arid rural areas in Tanzania predominantly lack access to clean, reliable, sustainable, and affordable energy for cooking, lighting and electrification; with also scarcity in fertile lands. Thus, practices that lead to environmental degradation such as rapid deforestation due to agricultural land expansions, charcoal making and firewood collection in these areas are very common. He explained that biogas plants of continuous low solid anaerobic digestion design were introduced in the area to address the unsustainable energy supply but because of the climate in the region most of the installed plants turned unsustainable and unreliable, hence the need for more reliable renewable energy technologies such as solar and wind in the area.
