Challenges in humanitarian information management and exchange: evidence from Haiti

There is a growing recognition of the critical role information management can play in shaping effective humanitarian response, coordination and decision‐making. Quality information, reaching more humanitarian actors, will result in better coordination and better decision‐making, thus improving the response to beneficiaries as well as accountability to donors. The humanitarian response to the 2010 Haiti earthquake marked a watershed moment for humanitarian information management. Yet the fragmented nature of the response and the use of hierarchical models of information management, along with other factors, have led some observers to label the Haiti response a failure. Using an analytical framework often found in humanitarian emergencies, this study analyses challenges to information flow in the Haiti case and the implications for effective humanitarian response. It concludes by offering possible paths for overcoming such challenges, and for restoring the value and utility of humanitarian information management and exchange in humanitarian relief settings.     

EU policy on the move – mobility and domestic translation of the European Union’s renewable energy policy

We discuss how the EU’s Renewable Energy Directive was designed to be mobile, and how it was moved to and implemented in Finland by translating it to enhance wood-based energy production through specific subsidies. We study policy-making as a mobile process, which approach has its original roots in political science and more recent basis in political geography. The article aims to develop conceptual understanding of how the mobility of a supranational policy is generated and how a policy is translated into complex and contentious geographical contexts. We aim to show that mobility of a directive is enabled by an empty governance space which is aimed to be ‘filled in’ in each spatial context, and that the filling in process makes each translation a contentious and path-dependent process. In Finland, the selected policy tools and practices continued the path-dependent ways of favouring forestry industry’s traditional position as the primary utiliser of forest resources.     

US National Park Buffer Zones: Historical, Scientific, Social, and Legal Aspects

/ This review will trace the evolution of beyond boundary/buffer zone thinking and policy responses in the US National Park Service (NPS); address buffer zone science, benefits, and limitations; examine pertinent legal and social concerns; highlight some agency attempts to create buffer zone-like areas; and propose highlights of a protected area strategy, with buffer zones and corridors as one component. Some findings follow. The need to expand national parks to accommodate large ungulate movement began in the late 1800s, but the recognition that such land was also needed to thwart human impacts such as poaching surfaced in the 1930s. External park buffer zone recommendations by 1930s park scientists were not implemented, and other related adopted policy forgotten, supporting the belief that great insight can be discovered in forgotten institutional history. Buffer zones can remedy some impacts but not others, but their benefits are multiple and underappreciated. The science of buffer zones is very immature and deserves more attention. A present primary obstacle to creating park buffer zones and connecting corridors is a social climate opposing federal initiatives that may intrude on the rights of private landowners. Some proactive NPS bufferlike activity examples are reviewed, but there were none where permanent, complete, effective nonlegislated park buffer zones, derived from nonfederal property, circumscribed large natural area parks. The need for buffer zones and corridors may be a symptom of inadequate regional planning. Options to create buffer zones from private and federal land are outlined. A comprehensive, overall protected area strategy must include more than just buffer zones, with highlights provided. Because optimal regional planning for US national parks is now thwarted by land-use politics, American society must soon decide what is most crucial to future well-being.

Indicators of Sustainability: Challenges and Opportunities at the Interface of Science and Policy

Rising global interest in sustainability has triggered attention in indicators as a means of achieving a more sustainable world. Although the search for indicators has led to the development of criteria for good indicators, it has also been dominated by scientific elites. The consequences of such dominance leads to significant social and policy implications, particularly with regard to how the search for sustainability has become defined primarily as a technical/scientific exploration when it is actually a moral and ethical issue. Our discussion about sustainability and appropriate indicators centers on what constitutes the public interest, a question that requires inclusiveness and centers on the interface of science and policy. The paper reviews the rationale for selecting indicators, the functions they serve, and the implications and consequences involved when one sector—science—dominates the debate. The paper concludes with suggestions about appropriate roles of science, policy and the public in the indicator selection process.     

Zero E-waste: Regulatory impediments and blockchain imperatives

• Copyrights on electronic products are impediments in promoting circular economy. • Manufacturers antagonize refurbishment and remanufacturing to maximize profit. • International harmonization of copyright laws will aid repair and remanufacture. • Blockchain–digital immutable ledgers–can promote trust among stakeholders. The concept of zero waste is an ideal situation that will require different solutions for different categories of waste. Electronic waste (E-waste), the fastest growing category of solid hazardous waste presents various unique challenges. Electronic product repair, reuse and remanufacture (3re) are crucial for effective source reduction of E-waste and the integration of the electronics industry into a circular or zero-waste economy framework. Increasingly, 3re implementation is restricted by regulatory difficulties, particularly the invocation of copyright laws. Here, we use the examples of electronic printer cartridges and restored compact discs (CDs) to identify the challenges and to explore solutions for managing the risks associated with E-waste through circular economy and the opportunities presented by innovative Blockchain solutions. A set of international consensuses on judicial definitions, such as 3re, refurbish fake/counterfeit product and copyright exhaustion, are proposed to accelerate source reduction in E-waste management toward the goal of zero waste.     

Pragmatic Approaches for Water Management Under Climate Change Uncertainty1

Stakhiv, Eugene Z., 2011. Pragmatic Approaches for Water Management Under Climate Change Uncertainty. Journal of the American Water Resources Association (JAWRA) 47(6):1183–1196. DOI: 10.1111/j.1752‐1688.2011.00589.x Abstract: Water resources management is in a difficult transition phase, trying to accommodate large uncertainties associated with climate change while struggling to implement a difficult set of principles and institutional changes associated with integrated water resources management. Water management is the principal medium through which projected impacts of global warming will be felt and ameliorated. Many standard hydrological practices, based on assumptions of a stationary climate, can be extended to accommodate numerous aspects of climate uncertainty. Classical engineering risk and reliability strategies developed by the water management profession to cope with contemporary climate uncertainties can also be effectively employed during this transition period, while a new family of hydrological tools and better climate change models are developed. An expansion of the concept of “robust decision making,” coupled with existing analytical tools and techniques, is the basis for a new approach advocated for planning and designing water resources infrastructure under climate uncertainty. Ultimately, it is not the tools and methods that need to be revamped as much as the suite of decision rules and evaluation principles used for project justification. They need to be aligned to be more compatible with the implications of a highly uncertain future climate trajectory, so that the hydrologic effects of that uncertainty are correctly reflected in the design of water infrastructure.
