Contesting market-based conservation: Payments for ecosystem services as a surface of engagement for rural social movements in Mexico

The Mexican National Payment for Ecosystem Services (PES) programs, which provide financial incentives for rural landholders to conserve forest, were originally designed under the logic of market-based conservation. Based on a multi-sited, multi scalar ethnography of the Mexican national PES programs, this article examines the process through which a national rural social movement was able to redefine the market-based narrative of PES, the historical and political context that provided this window of opportunity, and the ways in which their engagement led to a hybridization of the policy itself. The involvement of the rural social movement introduced a very different conception of PES – as a recognition by Mexico’s federal state and urban society of the value of campesino environmental stewardship and an economic support to allow them to remain on the land. Their direct involvement in the redesign of the programs had a significant impact on their conformation that reflected this vision of revaluing the rural: the inclusion of agroforests and sustainably managed timber lands; requirements for self-defined forest management plans; provision of dedicated funding for technical assistance; and the training of local extensionists. I believe that in mapping the evolution of the Mexican national PES program we can begin to see how, in this particular place and time, rural social movements employed PES as a "useful surface of engagement" (Escobar 1999, p. 13) for contesting the market-based notions of the federal state, international lending institutions and conservation NGOs. I position this analysis in the context of the global project of “grabbing green” and as an example of the frictions that can inhibit and even partially reverse the logic of the seemingly inexorable rise of market-based conservation policy and projects

Beyond The Gap:Placing Biodiversity Finance in the Global Economy

Governments and conservation organisations often point to a large gap between existing financial resources and the resources needed to achieve biodiversity objectives. But the gap is almost always presented without context, as though biodiversity loss will be resolved through increased funding alone. To illuminate crucial pathways for transformative change, this report examines the political and economic dimensions of biodiversity loss. “Beyond the gap: placing biodiversity finance in the global economy” addresses two questions: how does the organization of the global economy drive biodiversity loss, and how has existing biodiversity finance performed? Trade, investment and financial regulation (or lack thereof), global economic pressures that push biodiverse countries into debt, and inequality across racialized, gender, class and colonial lines, all drive biodiversity loss and require urgent attention. Instead of transformation, a series of voluntary measures and market-based mechanisms such as payments for ecosystem services or blended finance schemes have been presented as tools to span the resource gap. This report shows that these efforts are marginal at best, and, at worst, entrench the power of rich world governments and non-state institutions like banks, large international NGOs, and supranationals. It is apparent that we must move “beyond the gap”. Only by placing biodiversity loss in the global economy will it be possible to realize transformative, inclusive and equitable change. The authors offer concrete recommendations for negotiators, civil society organizations, and activist groups to push questions of biodiversity finance beyond the gap

No Differential Regulation of Dopamine Transporter (DAT) and Vesicular Monoamine Transporter 2 (VMAT2) Binding in a Primate Model of Parkinson Disease

Radioligands for DAT and VMAT2 are widely used presynaptic markers for assessing dopamine (DA) nerve terminals in Parkinson disease (PD). Previous in vivo imaging and postmortem studies suggest that these transporter sites may be regulated as the numbers of nigrostriatal neurons change in pathologic conditions. To investigate this issue, we used in vitro quantitative autoradioradiography to measure striatal DAT and VMAT2 specific binding in postmortem brain from 14 monkeys after unilateral internal carotid artery infusion of 1-Methyl-4-Phenyl-1,2,3,6-tetrahydropyridine (MPTP) with doses varying from 0 to 0.31 mg/kg. Quantitative estimates of the number of tyrosine hydroxylase (TH)-immunoreactive (ir) neurons in substantia nigra (SN) were determined with unbiased stereology, and quantitative autoradiography was used to measure DAT and VMAT2 striatal specific binding. Striatal VMAT2 and DAT binding correlated with striatal DA (rs = 0.83, rs = 0.80, respectively, both with n = 14, p<0.001) but only with nigra TH-ir cells when nigral cell loss was 50% or less (r = 0.93, n = 8, p = 0.001 and r = 0.91, n = 8, p = 0.002 respectively). Reduction of VMAT2 and DAT striatal specific binding sites strongly correlated with each other (r = 0.93, n = 14, p<0.0005). These similar changes in DAT and VMAT2 binding sites in the striatal terminal fields of the surviving nigrostriatal neurons demonstrate that there is no differential regulation of these two sites at 2 months after MPTP infusion

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

The Economics of Collective Brands

We consider the consequences of a shared brand name such as geographical names used to identify high quality products, for the incentives of otherwise autonomous firms to invest in quality. We contend that such collective brand labels improve communication between sellers and consumers, when the scale of production is too small for individual firms to establish reputations on a stand alone basis. This has two opposing effects on member firms' incentives to invest in quality. On the one hand, it increases investment incentives by increasing the visibility and transparency of individual member firms, which increases the return from investment in quality. On the other hand, it creates an incentive to free ride on the group's reputation, which can lead to less investment in quality. We identify parmater values under which collective branding delivers higher quality than is achievable by stand alone firms
