Privatizing conditions of production: trade agreements as neoliberal environmental governance

Recent multilateral trade agreements are among the major manifestations of neoliberalism. They are also emerging as some of the most important sites of environmental governance in the 21st century. I argue here that these trade agreements, particularly the sweeping new protections they provide for investors, are redefining property rights and environmental governance in fundamental ways. I suggest that in addition to furthering the centuries-long process of the enclosure of nature under capitalism, the neoliberal agenda of NAFTA and similar trade agreements also involves something new: the privatization, or primitive accumulation, of conditions of production as an accumulation strategy. I explore these dynamics through examination of two cases, one in the United States and one in Mexico. I also explore the roles of social movements in these dynamics.     

The neoliberalization of ecosystem services: wetland mitigation banking and problems in environmental governance

Wetland mitigation banking is an American neoliberal environmental policy that has created a functioning market in `ecosystem services', commodities defined using the holistic measures of ecological science. The development of this market is discussed as a project of environmental governance, defined as the nation-state's regulation of ecological relations within its territory towards stabilizing capitalist relations of power and accumulation. I argue that the wetland banking industry serves as a bellwether that presages problems that other strategies of neoliberal environmental governance will experience. Ethnographic, economic and ecological data from the Chicago-area wetland banking industry inform a discussion of two major obstacles to neoliberal strategy: the problem of relying on ecological science to define the unit of trade, and the problem of aligning the somewhat independent relations of law, politics, markets and ecosystems across an array of spatial scales. Theoretical guidance is sought from recent work on `social natures' and from the Regulationist approach to institutional political economics.     

Regions and sustainable development: regional planning matters

This paper looks at how the term 'sustainable development' has been used in the process of regional plan making over the past decade. It emphasizes the differing geographies of these debates within England, in terms of how sustainable development has been used to justify different types of approach in different parts of the country. Both drawing on and challenging recent work on state theory, the paper argues the need to see regional planning as a part of a multi-scalar governance system, whose importance should not be underestimated.     

Systematic position ofMucronella perforata Okada et Mawatari 1937

Mucronella perforata was first discovered from Onagawa Bay, northern Honshu, Japan, in 1937 by Okada and Mawatari. It was reported from Hong Kong and its neighboring waters and was referred to the genusHippopodina Levinsen, 1909 of the Family Hippopodinidae Levinsen, 1909 by Huang et al. (1990) and Huang (1994). According to the astogeny of the species, both the ancestrula and its successor zooids have an ascus proximal to the orifice, and its hyperstomial ovicells are imperforate, so it could not be a member of any known genus of the known families of the superfamily Schizoporelloidea Jullien, 1883 in the infraorder Lepraliomorpha Gordon, 1989. The new genusPacificincola and the new family Pacificincolidae established respectively on the basis of reexaminations of the Chinese specimens obtained from the southern Yellow Sea, the East China Sea and the northern South China Sea.Schizoporella insculpta Hincks, 1880 andHippoporina mexicana Soule, Soule et Chaney, 1995 have been referred to the new genus in the paper.

New Modes of Environmental Governance in Greater Sage-Grouse Conservation in Oregon

Abstract

Natural resource challenges often span administrative jurisdictions and include actors and processes operating at different spatial and political scales. We applied concepts of new environmental governance to analyze Oregon’s approach to greater sage-grouse conservation. Through one in-depth case study in Lake County, we traced features of new environmental governance (cross-scale interactions, decentralization, and capacities of actors) through different governance levels. Interviews and qualitative analysis revealed that decentralization of administrative functions facilitated cross-scale interactions and relied on intermediaries, gap-filling, and perceptions of legitimacy at lower levels. State and agency guidelines steered the effort and were accompanied by financial and technical resources from multiple arenas, which increased local capacity. This study adds to the understandings of environmental governance for implementing multi-actor, multi-level conservation arrangements in resource-dependent communities. Further exploration of connections between higher levels and local contexts will reveal important, new ways to link policies with on-the-ground outcomes.     

Linking multi-level governance to local common-pool resource theory using fuzzy-set qualitative comparative analysis: Insights from twenty years of biodiversity conservation in Costa Rica

Understanding the relationship between multi-level institutional linkages and conditions influencing the likelihood of successful collective action has practical and theoretical relevance to sustainable local resource governance. This paper studies the relationship between multi-level linkages and local autonomy, a facilitating condition found to increase the likelihood of local successful collective action. A technique known as fuzzy-set qualitative comparative analysis (fsQCA) was applied to a longitudinal comparative data set. In the context of the decentralization of a protected area system in Costa Rica (1986–2006), it traced the emergence and endurance of autonomy among local institutions for biodiversity conservation. The technique illustrates which set of multi-level linkages combined in different ways, and at different points in time, to reach the same outcome (local autonomy). The findings show that a unique set of combinations of multi-level linkages led to the emergence of local autonomy among institutions for biodiversity conservation governance. In contrast, a more diverse set was associated with the endurance of local autonomy over time, suggesting that institutional diversity may play a more prominent role in the maintenance of institutional robustness than in processes of institutional emergence.     

Contested hydrosocial territories and disputed water governance: Struggles and competing claims over the Ilisu Dam development in southeastern Turkey

Dam development in southeastern Turkey is a highly-disputed issue, fanned by the Turkish–Kurdish conflict, socio-environmental and historical–cultural concerns, and international geopolitical interests. This paper focuses on discussions around the Ilisu Dam and shows how different actor coalitions imagine different hydrosocial territories regarding this mega-hydraulic project currently under construction. Imaginaries, counter-imaginaries and endeavours to materialize them go far beyond technical projects, portraying the dam to (re)configure the territory physically, ecologically, socio-economically, symbolically and discursively. The paper embeds competing hydro-territorial constructs and claims within an analysis of governmentality and the multi-scalar and multi-issue politics of dam opponents.     

Down to Earth: Contextualizing the Anthropocene

The ‘Anthropocene’ is now being used as a conceptual frame by different communities and in a variety of contexts to understand the evolving human–environment relationship. However, as we argue in this paper, the notion of an Anthropos, or ‘humanity’, as global, unified ‘geological force’ threatens to mask the diversity and differences in the actual conditions and impacts of humankind, and does not do justice to the diversity of local and regional contexts. For this reason, we interpret in this article the notion of an Anthropocene in a more context-dependent, localized and social understanding. We do this through illustrating examples from four issue domains, selected for their variation in terms of spatial and temporal scale, systems of governance and functional interdependencies: nitrogen cycle distortion (in particular as it relates to food security); ocean acidification; urbanization; and wildfires. Based on this analysis, we systematically address the consequences of the lens of the Anthropocene for the governance of social-ecological systems, focusing on the multi-level, functional and sectoral organization of governance, and possible redefinitions of governance systems and policy domains. We conclude that the notion of the Anthropocene, once seen in light of social inequalities and regional differences, allows for novel analysis of issue-based problems in the context of a global understanding, in both academic and political terms. This makes it a useful concept to help leverage and (re-)focus our efforts in a more innovative and effective way to transition towards sustainability.
