“Value Grabbing”: A Political Ecology of Rent

This paper aims to redress the under-appreciated significance of rent for political ecological analysis. We introduce the notion of value grabbing, defined as the appropriation of (surplus) value through rent. A concept that is analytically distinct from accumulation, rent is both a social relation and a distributional process that is increasingly central to the reproduction of contemporary capitalism. Emphasis is placed on the “grabbing” of value in order to shed light on the processes at work by which surplus value is distributed unevenly between different classes and fractions of classes. A focus on rent within political ecology, we argue, can help us distinguish between two organically related but analytically distinct “moments”: (a) the creation of property rights that establish rent relations and (b) the struggle over the appropriation and distribution of surplus value generated by the rent relation itself. We explore some of the implications of this perspective for understanding new forms of socio-ecological struggles and their varied relations to the state. We maintain that a value-grabbing perspective has far-reaching consequences for political ecology, as it provides a sharp conceptual tool for situating a wide range of socio-ecological conflicts and movements as class struggles over value appropriation and distribution.     

Emancipatory rural politics: confronting authoritarian populism

A new political moment is underway. Although there are significant differences in how this is constituted in different places, one manifestation of the new moment is the rise of distinct forms of authoritarian populism. In this opening paper of the JPS Forum series on ‘Authoritarian Populism and the Rural World’, we explore the relationship between these new forms of politics and rural areas around the world. We ask how rural transformations have contributed to deepening regressive national politics, and how rural areas shape and are shaped by these politics. We propose a global agenda for research, debate and action, which we call the Emancipatory Rural Politics Initiative (ERPI, www.iss.nl/erpi). This centres on understanding the contemporary conjuncture, working to confront authoritarian populism through the analysis of and support for alternatives.     

Power and property: commercialization,enclosures, and the transformation of agrarian relations in Ethiopia

The transnational agrarian social movement Vía Campesina is campaigning to have the United Nations negotiate and implement a Declaration, and eventually an International Convention, on Peasants' Rights. This article analyzes the origins and demands of the campaign and the place of the claimed rights in international law. Peasant organizations hope to follow in the footsteps of indigenous peoples' movements that participated in the negotiations preceding the 2007 UN Declaration on the Rights of Indigenous Peoples. The peasants' rights campaign has succeeded in linking its demands to discussions of the right to food in the United Nations, where concern is growing over the approach of the 2015 target for realizing the Millennium Development Goals, in particular the halving of the numbers of people suffering from hunger. The campaign is likely to face stiff resistance from powerful UN member states, but could achieve substantial advances even if the path to a convention is difficult or never completed.     

Identification and age estimation of blood stains on colored backgrounds by near infrared spectroscopy

Non-destructive identification and subsequent age estimation of blood stains are significant steps in forensic casework. The latter can provide important information on the temporal aspects of a crime. As previously shown, visible spectroscopy of blood stains on white backgrounds can successfully be used for their identification and age estimation. The use of this technique however, is hampered by dark backgrounds. In the present study the feasibility to use near infrared (NIR) spectroscopy was evaluated for blood stain identification and age estimation on dark backgrounds. Using NIR reflectance spectroscopy, blood stains were distinguished from other substances with 100% sensitivity and 100% specificity. In addition, Partial Least Squares Regression analysis was applied to estimate the age of blood stains on colored backgrounds. The age of blood stains up to 1 month old was estimated successfully with a root mean squared error of prediction of 8.9%. These findings are an important step toward the practical implementation of blood stain identification and age estimation in forensic casework, where a large variety of backgrounds can be encountered.
