Model tuning and its impact on modelled climate change response: Hudson Bay sea ice, a case study

The impact of climate model parameterization is examined using Hudson Bay sea ice as a case study. The implicit diffusion of an upstream scheme used in a three dimensional ocean general circulation model is locally determined by using a one dimension proxy model of Hudson Bay with atmospheric, cryospheric and oceanic components. Using this proxy model, distinct pairs of values for the thermal conductivity of sea ice and thermal diffusivity of sea water are found that reproduce the current climatology of sea ice thickness in Hudson Bay. These pairs of values are subsequently used in a 3°C warming scenario. The resulting ice thicknesses are shown to be highly dependent on the choice of these pairs of values as well as the seasonal distribution of the warming.     

Unconventional Gas Development: Why a Regional Community Said No

Public concern resulting from unconventional coal seam gas (CSG) exploration and production has become a contentious planning issue in regional Australia, with public concern drawing attention to government planning obligations. To assist Lismore City Council (Northern New South Wales) in its deliberations on the topic, a referendum‐style poll on the issue of CSG industry development was held in conjunction with the local government elections of September 2012. The poll question, ‘Do you support CSG exploration and production in the Lismore City Council area?’, elicited a poll response rate of 97% of eligible voters, of which 87% voted ‘no’. This paper reports the results of an exit poll survey using the Theory of Planned Behaviour to frame motivations behind the poll result, and examines the role of the poll and exit poll survey in providing a process of deliberative democracy in the context of the CSG debate. Key details highlighted by the results were that non‐supporters of CSG exploration were primarily concerned about water quality, while supporters saw the primary benefit being regional employment. Emerging themes of this study are the need for more independent research on potential risks and benefits of CSG developments, increase in institutional transparency, and the development of renewable alternatives. The study concludes that the principles of deliberative democracy involved in the Lismore City Council poll and subsequent exit poll survey have provided an opportunity for a more open discussion and genuine discourse within the CSG debate.     

Mining amid armed conflict: nonferrous metals mining in the Philippines

In recent years the government of the Philippines has attempted to accelerate the growth of the nation's economy by encouraging the extraction of its mineral resources by multinational corporations. The Philippines is also a nation beset by armed violence carried out by anti-state groups. This article discusses how the presence, and activities, of these groups generate problems for a mining-based development paradigm. The article examines: the literature on the topic of natural resource abundance and conflict, how there have been attacks upon mines by armed groups, how mining companies have served as a target of extortion, how grievances related to mining can act as a source of conflict, how mining could disrupt the peace process with the Moro Islamic Liberation Front and how mines are accompanied by a militarization of the area in their vicinity. Ultimately, violence is a manifestation of poverty and social exclusion inherent in Philippine society. Mining may not diminish, and indeed may increase, this poverty and social exclusion. Unless poverty and social exclusion is alleviated the violence will continue and alternative efforts to develop the Philippine economy will be precluded.     

In from the margins? The changing place of Africa in International Relations

This article surveys recent literature on Africa and International Relations (IR) and reviews the current place of Africa within the discipline. It notes that critical debates continue around claims of a mismatch between Africa and ‘mainstream’ IR theories and concepts. However, alongside this set of issues, there is in fact a burgeoning literature on many aspects of Africa's international relations. While some of these studies utilize existing IR theories, and others explore empirical cases that could deliver important lessons for the wider discipline, much of this promise goes unfulfilled. The article reviews literature on China's role and on HIV/AIDS governance in Africa to illustrate how the study of African international relations, the wider IR discipline and international policy could all benefit from a closer engagement between Africa and IR. The article concludes by setting out three challenges for a renewed agenda: a need to address the problematic relationship between universal analytical concepts and regional particularities; a need to give recognition to, and analyse, African agency in international politics; and a need to address inequalities in knowledge production in the field of Africa's international relations.
