Consultas and Socially Responsible Investing in Guatemala: A Case Study Examining Maya Perspectives on the Indigenous Right to Free,Prior, and Informed Consent

Since 2005, more than 78 Maya communities representing approximately one million Guatemalans have held referendums called consultas comunitarias, which ask the community whether they are in agreement with mineral, hydroelectric, and/or other megaprojects in their traditional territory. Participation in the consultas is a form of resistance to the granting of mineral rights to corporate interests. In Canada, where much of the Guatemalan mining investment is based, “socially responsible investment firms” (SRIs) promote corporate respect for Indigenous rights. Based on interviews and participant observation, we highlight the perspectives of Maya consulta organizers in three communities that have undertaken consultas to resist the mining licenses of the Canadian mining company Goldcorp, Inc. We argue that a strict policy of corporate respect for the right to free, prior, and informed consent of affected communities is a minimum requirement for Maya acceptance of SRI legitimacy.     

Interpreting the Civil Rights Movement: Place,Memory, and Conflict

Produced over the past decade, monuments and museums dedicated to the Civil Rights movement of the 1950s and 1960s have desegregated America's memorial landscape. Tracing a broad arc across the US South, the material elements of this landscape — historic markers, monuments, parks, registered buildings, and museums — present a distinct challenge to representations of an elite, white American past. This challenge, however, is offered in a distinctly gendered manner, inasmuch as the role of women in organizing and leading the movement is obscured. Further, the historical narratives concretized at these sites are mediated by conventions associated with civil rights historiography and the tourism development industry. The result is a complex, sometimes ironic landscape. Via the narratives they embed and the crowds they attract, these landscapes are co-constitutive with contemporary politics of representing the past in the United States. This paper offers an overview of current memorial practices and representations of the Civil Rights movement found at the country's major memorial landscapes.     

Contemporary Geographies of Indigenous Rights and Interests in Rural Australia

More than half of Australia's lands and coastal regions are now encompassed within the boundaries of native title claims. The claims and the 'native title communities' who have lodged them are shaping a new geography of Australia's lands and seascapes. These communities derive from traditional ownership and thus have a different, and more fundamentally authoritative, basis to the indigenous 'residential communities' whose representative organisations are the mechanism through which governments have promoted indigenous self-management and which dominate in public affairs. Recognition of native title provides some opportunities for indigenous people to negotiate for benefits which will address their marginalised and economically dependent status but these are limited by the protection given to non-indigenous interests and are often proving they can be very difficult to realise. Overcoming indigenous marginalisation, promoting co-existence between indigenous and other Australians, and securing sustainability in rural regions requires that institutional reform goes beyond legally bounded interpretations of where native title does and does not still exist. Rebuilding indigenous institutions for governance of country is fundamental to achieving necessary change but political will and resources to support the process are critically lacking.     

An assessment of the current status of the chokka squid fishery in South Africa and an evaluation of alternative allocation strategies

The South African squid fishery is based on a single species, Loligo reynaudi, locally referred to as chokka and commonly found around the Agulhas Bank and West Coast shelf of South Africa. The existing long term rights for participation in the fishery expire at the end of 2013 and a new set of rights will have to be issued. Progress made to date in achieving the objectives of the South African Marine Living Resources Act of 1998 (MLRA), including progress towards greater equity, will be an important consideration in allocation decisions. The draft Small-Scale Fisheries Policy, scheduled to be adopted in 2013, could also influence the criteria to be used. This study updates the information on the current structure and functioning of the squid jig sector and considers the likely performance of two alternative access allocation scenarios against the current and evolving policy goals. The study reaffirms that the squid fishery is an important contributor to human well-being in South Africa and particularly in the Eastern Cape Province but there is scope for improvement in the extent of transformation and equity. The study concludes that, as a result of a common lack of experience and capital amongst potential new entrants, the risks associated with transformation in this fishery are likely to be high, especially if the option of allocating rights to community-based legal entities was to be used. The risks could be reduced by ensuring that a number of pre-conditions were met. These include, amongst others, not allowing total effort in the fishery to increase; ensuring effective management by the responsible government authorities; adequate capacity building of new entrants, whether individuals or cooperatives; and ensuring new entrants have viable business plans.     

Rights-based management in the Western and Central Pacific Ocean tuna fishery: Economic and environmental change under the Vessel Day Scheme

Defining, strengthening and enforcing rights over fisheries resources is frequently identified as central to overcoming ‘the tragedy of the commons’ and associated environmental and economic challenges in fisheries systems. Though economic theory generally suggests that output control (e.g. quotas) creates the strongest incentives for efficiency and conservation, input controls (e.g. on effort) remain common. This paper explores the rationale for, and implications of, employing a transferable effort scheme in one of the largest and most valuable fisheries. In 2007, eight Pacific Island countries implemented the Vessel Day Scheme with the aims of strengthening their rights over tuna resources and control over economic and environmental trends. Four years since implementation, the scheme has significantly increased economic returns for the island states and generated improvements in data reporting. However, it has not generated a firm limit on fishing effort and its structure has made it difficult to directly target the biological concerns of individual species within the multi-species fishery. In the future, outcomes of the Vessel Day Scheme will continue to be tempered by the structural limitations of effort-based regulatory scheme, market conditions in the sector and the willingness of firms and island states to clarify, abide by and enforce the technical components of the scheme.     

The right to move: informal use rights and urban practices of mobility

Everyday urban practices are enabled by both formal and informal rights regimes. Researchers often focus on the effects of formal rights; informal rights to use urban spaces have been less widely examined, particularly in North America. This article examines practices of intra-urban mobility in a gentrifying area of Portland, Oregon. We find that rights regimes regarding movement in urban space importantly shape who uses particular transit strategies and infrastructures. Specifically, we identify rights regimes rooted in explications of a city ideal and a neighborhood ethic. We suggest that Portland’s widely admired transit planning process has not sufficiently engaged with informal use rights in transit spaces, leading to uneven adoption of a transportation infrastructure that re-inscribes historic racialized injustices. An examination of informal use rights complicates common rights analytics, including those leveraging Lefebvre’s right to the city, emphasizing how all urban rights are contingent, contested and negotiated.     

Environmental narratives and politics in Tanzania's Rufiji Delta: A reply to Burgess et al.

This reply is in response to Burgess et al.’s Commentary on our original article, “The REDD Menace: Resurgent protectionism in Tanzania's mangrove forests.” Their commentary, we argue, shifts the focus from WWF's past conservation work and environmental narratives in the Rufiji Delta North, the subject of our article, to its current forest carbon inventory work. We do not comment on WWF's new work. Our principal concern remains on the environmental narratives crafted by WWF that were used to justify attempts to remove Warufiji small-scale rice farmers from the mangrove forests in the Rufiji Delta North. We emphasize the political implications of designating forest areas for carbon forestry and REDD projects in terms of forest dependent people's land and livelihood rights. We argue from environmental historical and social justice perspectives that the Warufiji should be counted among the winners, not the losers, in the green value chains currently under construction.

Are Territorial Use Rights in Fisheries (TURFs) sufficiently large?

Territorial Use Rights in Fisheries (TURFs) are gaining renewed attention as a potential tool for sustainable fisheries management in small-scale fisheries. This growing popularity comes despite the fact that there are still unresolved questions about the most effective TURF designs. One of the key questions is the role of TURF size in their efficacy both from ecological and social standpoints. This study explores the expected effects of existing TURF sizes on yields for TURF systems in Chile, México and Japan. The expected effect of larval dispersal and adult movement on yields was simulated for TURFs in each system. The results show that the analyzed TURF systems fall into three main categories: (a) TURFs that are of adequate size to eliminate the expected negative effects of both adult and larval movement, (b) TURFs that are large enough to eliminate the expected negative effects of adult movement, but not the effects of larval dispersal, and c) TURFs that are too small to eliminate the expected impacts on yield of both adult and larval movement. These analyses suggest that either existing models of TURF performance are incomplete or that there is significant scope for improved performance with altered TURF designs. Considering these alternatives, empirical evidence from the TURFs deemed too small suggests that complementary management tools can enhance TURF performance when natural or social constraints prevent the construction of TURFs of optimal size.
