Bioenergy, food security and poverty reduction: trade-offs and synergies along the water-energy-food security nexus

This article provides a review of trade-offs and synergies of bioenergy within the water–energy–food security nexus, with emphasis on developing countries. It explores the links of bioenergy with food security, poverty reduction, environmental sustainability, health, and gender equity. It concludes that applying the nexus perspective to analyses of bioenergy widens the scope for achieving multiple-win outcomes along the above aspects.

Bioenergy, Food Security and Poverty Reduction: Mitigating tradeoffs and promoting synergies along the Water- Energy-Food Security Nexus

Modern bioenergy is a core ingredient of sustainable economic development as it plays an important role in poverty reduction and green growth. This makes bioenergy innovations critical, especially in developing countries where many households and rural communities rely on traditional bioenergy. Managing the multiple tradeoffs among bioenergy use, agricultural productivity, and ecosystem functions is a major development challenge. Addressing this challenge requires the identification of the drivers, tradeoffs and impacts of bioenergy production, trade and use in the Water, Energy and Food Security Nexus. The key objective of this paper is to provide an analytical framework and assess the track record of policy actions to stimulate modern bioenergy innovation in order to achieve multiple-win outcomes in terms of poverty alleviation, improved health and gender empowerment and environmental sustainability. We begin by describing the global trends and drivers in bioenergy production, trade and use. Secondly, we review the state of the art on impacts and links of bioenergy with the other Nexus components. Thirdly, we suggest a conceptual framework for evaluating the synergies and tradeoffs of bioenergy with other bioeconomic and economic activities along the Nexus. Follow-up empirical research at household and community levels in several developing countries will be based on this framework. Finally, a discussion on the conceptual framework is enriched by insights on the relevant actors, the tools and mechanisms specific to these actors for catalyzing innovations in the bioenergy for development.

Decentralized Energy in Water-Energy-Food Security Nexus in Developing Countries: Case Studies on Successes and Failures

Access to modern energy is vital for sustainable development. In rural areas, decentralized energy solutions may play a significant role in reducing poverty, supporting community institutions and facilitating the generation of basic services such as communication, water access, education and health services. However, the majority of dwellers in off-grid communities in developing countries have little or no access to modern energy technologies, although they are endowed with a vast potential of renewable energy resources. Decentralized energy solutions could serve as an option to solve this energy access problem. However, the previous literature indicates that there are financial, technical, infrastructural, and institutional constraints to scale up decentralized energy options. This paper seeks to study the underlying factors behind the successes and failures of household- and community-based decentralized energy technologies through local case studies from different parts of the world, analyzed through the lenses of the Water-Energy-Food Security (WEF) nexus. First, the paper reviews the literature on the main benchmarks used to evaluate the success and failure of community-based energy. Second, the conceptual framework relating decentralized energy to the WEF nexus elements is briefly described. Thirdly, the methods and data used in the paper are described, followed by the presentation of the case studies. Lastly, the paper is concluded by drawing policy lessons and recommendations. Further empirical studies are recommended to quantitatively evaluate the impacts of decentralized energy solutions on the welfare of households and communities within the framework of the Water-Energy-Food nexus.

Energy security, uncertainty and energy resource use options in Ethiopia

Ethiopia’s energy sector faces critical challenges to meeting steadily increasing demand given limited infrastructure, heavy reliance on hydroelectric power, and underdevelopment of alternative energy resources. The main aim of this paper is to investigate an optimal least cost investment decisions for integrated energy source diversification. We seek to contribute to the relevant literature by paying particular attention to the role of public policy for promoting renewable energy investment and to better understand future energy security implication of various uncertainties. Dynamic linear programming model created using General Algebraic Modelling Systems (GAMS) software was used to explore the national energy security implications of uncertainties associated with technological and efficiency innovations, and climate change or drought scenarios. To cope with the impacts of drought on hydroelectric power production Ethiopia would need to invest in the development of alternative energy resources. This would improve sustainability and reliability, but these changes would also increase production costs. But greater technical and efficiency innovations found to improve electricity diversification, reduce production costs and shadow prices or resources scarcity; and are, thus, key for reducing the risks posed by drought and for enhancing energy security.
