Clever Ketlogetswe, Jerekias Gandure
Journal of Sustainable Bioenergy Systems (JSBS) , 2018, DOI: 10.4236/jsbs.2018.83006
Abstract: Although renewable energy technologies applications to rural communities to improve energy access have been embraced in numerous parts of the world, sustainability of these systems is increasingly becoming critical as far as realization of long term benefits is concerned. The current manuscript proposes approaches deemed to provide appropriate match between technology and users in a select of Botswana’s rural communities. The methodology includes a participatory and inclusive approach in which the local community is engaged in the generation of their own energy. Available information indicates that available feedstock in selected communities is sufficient to generate and provide sustainable energy supply for the community.

Advances in micro-electro-mechanical systems (MEMS) and information communication technology (ICT) have facilitated the development of integrated electrical power systems for the future. A recent major issue is the need for a healthy and sustainable power transmission and distribution system that is smart, reliable and climate-friendly. Therefore, at the start of the 21st Century, Government, utilities and research communities are working jointly to develop an intelligent grid system, which is now known as a smart grid. Smart grid will provide highly consistent and reliable services, efficient energy management practices, smart metering integration, automation and precision decision support systems and self healing facilities. Smart grid will also bring benefits of seamless integration of renewable energy sources to the power networks. This paper focuses on the benefits and probable deployment issues of smart grid technology for a sustainable future both nationally and internationally. This paper also investigates the ongoing major research programs in Europe, America and Australia for smart grid and the associated enabling technologies. Finally, this study explores the prospects and characteristics of renewable energy sources with possible deployment integration issues to develop a clean energy smart grid technology for an intelligent power system.

Journal of Applied Technology in Environmental Sanitation , 2011,
Abstract: Nigeria is endowed with enormous surface and groundwater resources, yet the provision of potable and safe water supply is still inadequate. So many programmes to improve rural water supply had been launched by many government agencies and international organizations. Even with the perceived economic expansion in the country, the coordination of the activities in the context of sustainable rural water supply situation is still poor, resulting to attention not been paid to the quality of water supplied to rural communities. Sustainable rural water supply in Nigeria entails the effective utilization of available surface and groundwater resources to satisfy the country’s present and future water needs in terms of quality and quantity. This paper therefore proposes and recommends a simple community based water resources management model, and presents novel concepts as well as new parameters to find a sustainable option of safe drinking water through active participation of local people. The paper also identifies the role of communities in sustainable rural water supply and examines the measures needed to operate and maintain the water sources efficiently in Nigeria in line with the present government’s vision 20:2020. Above all, the paper indicates that intelligent and accountable water resources management will not be established without the conscientious participation of local people.
Sustainable Supply of Energy from Biomass

Latvian Journal of Physics and Technical Sciences , 2010, DOI: 10.2478/v10047-010-0003-4
Abstract: The study concerns sustainable supply of primary energy from biomass and considers the interrelation between the amount of energy captured in biomass by photosynthesis and the total land area under perennial species grown for the purpose. The authors analyse available experimental data statistically relevant to natural growths comprising a large number of individual trees of grey alder (Alnus incana), a well-known fast-growing species broadly spread in Latvia and for centuries being used as firewood. By graphical approximation of the growth-rate data available for growths up to 50 years of age the optimum age for harvesting dependent on the age at which the maximum growth-rate of biomass is reached is shown to be 18 years confirming traditional popular knowledge. With account for long-term sustainable supply of energy under condition of 18-year rotation, the average yield of energy from highest quality sites of the total land area permanently occupied by alder is calculated to be ca. 85 GJ/ha and the required land equivalent - slightly less than 12 ha per TJ of primary energy from photosynthesis.
Compressed Sensing off the Grid  [PDF]

Mathematics , 2012,
Abstract: We consider the problem of estimating the frequency components of a mixture of s complex sinusoids from a random subset of n regularly spaced samples. Unlike previous work in compressed sensing, the frequencies are not assumed to lie on a grid, but can assume any values in the normalized frequency domain [0,1]. We propose an atomic norm minimization approach to exactly recover the unobserved samples. We reformulate this atomic norm minimization as an exact semidefinite program. Even with this continuous dictionary, we show that most sampling sets of size O(s log s log n) are sufficient to guarantee the exact frequency estimation with high probability, provided the frequencies are well separated. Numerical experiments are performed to illustrate the effectiveness of the proposed method.

Abstract: The concept of sustainable livelihood appeared in the report of an advisory panel of the World Commission on Environment and Development in 1987. The report refers to the human basic needs, food security, sustainable agriculture practice and poverty. Sustainable livelihood refers to a way of approaching development that incorporates all aspects of human livelihoods and the means whereby people obtain them. The study examines the factors that contribute to sustainable livelihood of the Orang Asli community in Malaysia. Based on a case study of Orang Asli communities in Pekan, Pahang, this study evaluates the level of sustainability of the communities using indicators covering economic, social and physical dimensions. Based on the regression analysis, total income, education level and health show positive relationship with sustainable livelihood while main job, marital status and dependents show negative relationship. The results suggest that higher level of education and income contribute to sustainable livelihood among the Orang Asli.

Abstract: Various new forms of settlements composed of sustainable communities are emerging all around the World as answers to the urban crises in great cities. These settlements differ, especially when comparing the countries where they appear. However they also have many common features, such as the humane scale and social community cohesion, public participation in their management, enforcing new societal values and sustainable orientation of activities. These settlements where developed following development of information and communication technology and correspond to the introduction of new styles of life and employment.

Abstract: Implementation of the concept of sustainable tourism development in the business of tour operators is based on the respect of environmental, social and economic aspects in all stages of the formation and execution of travel arrangements. For tour operators, the integration of these principles in the process of creating a supply chain and contracting services with providers is of particular importance. In this way, the tour operator can achieve a greater level of control over inputs included in a travel arrangement, guaranteeing the quality of customer services and taking responsibility in relation to other stakeholders. Experiences of tour operators in leading source markets have shown that it has long-term positive economic effects. Although tour operators face a number of difficulties in the process of integrating sustainable tourism in the supply chain, positive experience has shown that well-placed management system and intensive long-term cooperation with providers gives good results.
