Municipal solid waste generation is a rapidly increasing challenge that is leading to severe pollution and environmental degradation in many urban areas of developing countries. This study presents the Waste to Energy Recovery Assessment (WERA) framework, a new quantitative decision support model for initial evaluation and alternative comparisons of different thermochemical treatments of municipal wastes. The framework is used to study waste-to-energy (WtE) systems for Abu Dhabi, Riyadh, Tokyo, and New York. The results show that WtE systems can fulfill only 1.4–3.6% of 2014 electricity demand in the analyzed cases.

The small open economies of the Gulf and Southeast Asia are pioneers in the establishment of

Sovereign Wealth Funds (SWFs). The SWFs of countries like Qatar and Singapore are among the

world’s largest in terms of total asset size relative to Gross Domestic Product. This article looks

at the different compulsions behind the setting up of SWFs by small open economies.

Decision-makers often seek to design policies that support sustainable development. Prospective evaluations of how effectively such policies are likely to meet sustainability goals have nonetheless remained relatively challenging. Evaluating policies against sustainability goals can be facilitated through the inclusive wealth framework, which characterizes development in terms of the value to society of its underlying capital assets, and defines development to be potentially sustainable if that value does not decline over time.

In this research paper, the authors propose that future human mediated water availability in arid regions may be assessed by considering key projects that have been identified or proposed by regional experts and organizations. Using Multicriteria Decision Methods as a framework to organize a set of decision criteria and their relative salience, the likelihood of selection (and development) of a project can be determined and used to form expectations of future regional water availability. The authors apply this approach in a case study of Jordan.

Many energy consumers, and even analysts and policymakers, confront and frame energy and climate risks in a moral vacuum, rarely incorporating broader social justice concerns. Here, to remedy this gap, we investigate how concepts from justice and ethics can inform energy decision-making by reframing five energy problems — nuclear waste, involuntary resettlement, energy pollution, energy poverty and climate change — as pressing justice concerns.

Professor Meghan O'Sullivan was interviewed on November 15th, 2015 for a Wall Street Journal special section on energy, discussing the rapid transformation of the American energy sector in light of low fuel prices, new climate policies and other factors.

Water, energy, and food security are of critical concern as rising population growth and rapid urbanization place greater pressure on our natural resources. This study evaluates the growing internationalization of food production in water-scarce countries using the case of Saudi Arabia as a microcosm to illustrate the tradeoffs in resource consumption associated with crop selection and farming practices.

Integrated policy and planning is needed to effectively meet the challenges of growing water and energy inter-dependencies in many regions. Joint consideration of both water and energy domains can identify new options for increasing overall resource use efficiencies. In order to identify and realize such opportunities, however, detailed knowledge of current and emerging water–energy couplings is needed along with a nuanced understanding of key actors and agencies engaged in decision-making. In this paper we develop a systematic, analytical approach based on quantitative analysis of water and energy couplings, identification and characterization of key actors and groups using concepts from stakeholders theory, and employing notions from organization theory of boundary-spanning agents that can serve to bridge inter-organizational networks for water and energy planning. We apply this approach to conduct an in-depth investigation of water and energy resources in Jordan.

Saudi Arabia is the third-largest per capita water user worldwide and has addressed the disparity between its renewable water resources and domestic demand primarily through desalination and the abstraction of non-renewable groundwater. This study evaluates the potential costs of this approach in the industrial and municipal sectors, exploring economic, energy, and environmental costs (including CO2 emissions and possible coastal impacts). Although the energy intensity of desalination is a global concern, it is particularly urgent to rethink water supply options in Saudi Arabia because the entirety of its natural gas production is consumed domestically, primarily in petrochemical and desalination plants.
