The oil palm boom: socio-economic implications for Q’eqchi’ households in the Polochic valley, Guatemala

Abstract Oil palm (Elaeis guineensis) has become one of the most rapidly expanding crops in the world. Many countries have promoted its cultivation as part of a broader rural development strategy aimed at generating paid work and producing both export commodities and biofuels. However, oil palm expansion has often occurred at the expense of ecosystems and subsistence agriculture, and on lands riddled with tenure conflicts. In this article, we analyse the implications of the combined effect of labouring in oil palm plantations and land access on households, and we discuss how these implications affect human well-being in two indigenous communities of the Polochic valley, Guatemala. Combining participant observation, semi-structured interviews, and land-time budget analysis at household level, we reveal how oil palm cultivation increases incomes for plantation workers’ households, but decreases the productivity of maize cultivation, reduces the time that household members have available for other activities and, particularly, reduces women’s resting time. In contrast, households that focus more intensively on maize cultivation show higher degrees of food security and women can allocate more time to social activities. However, our results also show that maize consumption per capita has not decreased in households working in oil palm plantations since such crop is considered sacred by the Q’eqchi’ and plays a central role in their diet and culture. In conclusion, we argue that while working for an oil palm cultivation can increase specific elements of the basic material conditions for a good life, other aspects such as food security, health, freedom of choice, and social relationships can become deteriorated.

Pathways of rural change: an integrated assessment of metabolic patterns in emerging ruralities

Abstract While rural transformations are nothing new in human history, current processes of rural change occur under multiple forces at an unprecedented pace, involving profound and unexpected changes in land use and users, and rapid transformations in the metabolic patterns of rural systems. The present special section aims to shed light on current drivers and pathways of rural change by analyzing, under a common conceptual and theoretical framework, examples of new ruralities that are emerging as responses across different world regions. Within this context, this introduction presents: (1) common research questions of the six presented cases of rural change; (2) the general theoretical and methodological framework of integrated assessment of societal metabolism adopted to analyze rural systems and (3) the main contributions and conclusions that could be drawn from six context-specific case studies from Asia, Latin America and Europe.

Integrating energy and land-use planning: socio-metabolic profiles along the rural–urban continuum in Catalonia (Spain)

Abstract Abandoning fossil fuels and increasingly relying on low-density, land-intensive renewable energy will increase demand for land, affecting current global and regional rural–urban relationships. Over the past two decades, rural–urban relationships all over the world have witnessed unprecedented changes that have rendered their boundaries blurred and have lead to the emergence of “new ruralities.” In this paper, we analyze the current profiles of electricity generation and consumption in relation to sociodemographic variables related to the use of time and land across the territory of Catalonia, Spain. Through a clustering procedure based on multivariate statistical analysis, we found that electricity consumption is related to functional specialization in the roles undertaken by different types of municipalities in the urban system. Municipality types have distinctive metabolic profiles in different sectors depending on their industrial, services or residential role. Villages’ metabolism is influenced by urban sprawl and industrial specialization, reflecting current “new ruralities.” Segregation between work activity and residence increases both overall electricity consumption and its rate (per hour) and density (per hectare) of dissipation. A sustainable spatial organization of societal activities without the use of fossil fuels or nuclear energy would require huge structural and sociodemographic changes to reduce energy demand and adapt it to regionally available renewable energy.

Absolute order-of-magnitude reasoning applied to a social multi-criteria evaluation framework

A social multi-criteria evaluation framework for solving a real-case problem of selecting a wind farm location in the regions of Urgell and Conca de Barberá in Catalonia (northeast of Spain) is studied. This paper applies a qualitative multi-criteria decision analysis approach based on linguistic labels assessment able to address uncertainty and deal with different levels of precision. This method is based on qualitative reasoning as an artificial intelligence technique for assessing and ranking multi-attribute alternatives with linguistic labels in order to handle uncertainty. This method is suitable for problems in the social framework such as energy planning which require the construction of a dialogue process among many social actors with high level of complexity and uncertainty. The method is compared with an existing approach, which has been applied previously in the wind farm location problem. This approach, consisting of an outranking method, is based on Condorcets original method. The results obtained by both approaches are analysed and their performance in the selection of the wind farm location is compared in aggregation procedures. Although results show that both methods conduct to similar alternatives rankings, the study highlights both their advantages and drawbacks.

Adapting established instruments to build useful food sovereignty indicators

The recent context of global food emergency and ecological crisis has increased the relevance of peoples struggle for food sovereignty (FSv), which promotes the transformation of the dominant food system and claims ‘the right of peoples to healthy and culturally appropriate food produced through ecologically sound and sustainable methods, and their right to define their own food and agriculture systems’. Revisiting two Spanish and Catalan articles developing FSv indicators, this article aims at discussing the need and utility of developing FSv indicators at different territorial levels. Confronting these two territorial scales, the paper also identifies common steps that can facilitate other future processes of building FSv indicators. As a conclusion, the paper suggests that these processes of building indicators can contribute to providing political direction at different geographical scales for the implementation of the FSv proposal. At the same time, they favor the movements self-reflexivity in its practices while supporting the collective shaping of future actions.

USING THE MUSIASEM APPROACH TO STUDY METABOLIC PATTERNS OF MODERN SOCIETIES

This paper presents examples of application of the MuSIASEM approach (Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism). The text is organized as follows: Section 1 briefly discusses, using practical examples, the theoretical challenge implied by the quantitative analysis of complex metabolic systems. Complex metabolic systems are organized over multiple hierarchical levels, therefore, they require the adoption of different dimensions and multiple scales of analysis. This challenge has to be explicitly addressed by those performing quantitative analysis; Section 2 discusses two key characteristics to be considered when studying the evolution in time of the metabolic pattern of modern societies: the implications associated with changes in demographic structures Section 2.1 and, the need of providing an integrated analysis of the structural change of socio-economic systems (Section 2.2. Such an analysis can be obtained by integrating the two functional/structural parts: (i) the part in charge for the production; and (ii) the part in charge for the consumption of goods and services. Section 3 provides an example of an integrated analysis of the evolution in time of the metabolic patterns of European Countries (data from an ongoing European Project - SMILE). This analysis shows clearly the problem generated by the use of data referring to the societal level (characteristics of whole countries). Looking only at the characteristics of the black-box, neglecting the differences of key parts operating inside the black-box, can lead to erroneous interpretation of data (e.g. the theory of Environmental Kuznets Curves).

Local, Mixed and Global Organic Tomato Supply Chains: Some Lessons Learned from a Real-World Case Study

This chapter presents the evaluation of three organic tomato supply chains in Catalonia (Spain): the Local and Global supply chains, and a Mixed supply chain. The evaluation is based on a set of multidimensional indicators derived from different narratives: Commodity, Environmental and Livelihoods. In so doing, we identified the main challenges when implementing the supply chain approach, and propose some recommendations for its application. The supply chain approach proves to be very useful in identifying the critical points at which to intervene and/or improve the performance of food supply chains, but presents some disadvantages when it is used to compare the sustainability of food supply chains. Finally, we show that organic production is not enough to achieve a sustainable food provision system, and the context and the food supply chain in which organic food is commercialised also determine the sustainability of organic food production.

USING LINGUISTIC DESCRIPTIONS WITH MULTI-CRITERIA DECISION AID APPROACHES IN URBAN ENERGY SYSTEMS

Multi-Criteria Decision Aid (MCDA) methods include various collections of mathematical techniques related to decision support systems in non-deterministic environments to support such applications as facility management, disaster management and urban planning. This paper applies MCDA approaches based on qualitative reasoning techniques with linguistic labels assessment. The aim of this method is ranking multi-attribute alternatives in group decision-making with qualitative labels. Finally this method is applied to a case of urban planning in selection of the less energy consumption project in a geographical area in Catalonia.
