Pastures and Cash Crops: Biomass Flows in the Socio-Metabolic Transition of Twentieth-Century Colombian Agriculture

This article aims to situate a national case study of the global periphery at the core of the debate on the socio-ecological transition by drawing on new data of biomass flows in twentieth-century Colombia. We draw up a century-long annual series converting a wide set of indicators from Net Primary Production (NPP) into the final socioeconomic uses of biomass, distinguishing around 200 different categories of crops, forests, and pastures. Our calculations draw on FAOSTAT and several corpuses of national statistics. The results show a fall of 10% in total NPP related to land-use changes involving forest conversion. Throughout the twentieth century, pasture was the most relevant among domestic extraction. Allocations of cash crops to industrial processing rose while the figure for staple crops for primary food consumption stagnated. The critical role of cattle throughout all periods and the higher yields of the industrial cash crops are behind this profile. This might also mean the start of a new trend of using pasture land for more profitable export crops, which establishes a new inner frontier of land-use intensification. Lastly, the article points out the phases of the socio-metabolic transition of biomass, explores the changes in biomass flows by looking at the history of the main drivers, and identifies the socio-ecological impacts of deforestation and industrial agribusiness

The open veins of Latin America: Long-term physical trade flows (1900-2016)

Latin America has long played a key role in the global provision of natural resources. Most of the continent's economies are net exporters of low-value, primary products and importers of manufactured goods at a high price. This pattern of specialised trade has highly negative consequences for economic development, the environment, and the local population's wellbeing. Yet to date, little empirical evidence has been collected on Latin America's total contribution to the rest of the world's regions in historical perspective. Applying the Material Flow Accounting methodology, this paper estimates the physical and monetary trade of 16 Latin American economies between 1900 and 2016. Our results show that: (i) yearly net exports of materials went from 4 Mt to 610 Mt between 1900 and 2016, and greatly accelerated since the World War II. (ii) Latin America is a net exporter of most types of materials (fossil fuels, non-energy minerals and biomass), so it harbours socio-environmental problems associated with different types of extractivism. (iii) Different regional export patterns exist: Andeans export subsoil (mining and energy carriers) while the rest export soil (land-based products). The countries with the lowest net exports are the smallest in size and with the highest population density. (iv) Europe and the USA have historically received most of the imports, but since the end of the twentieth century, the Southeast Asia region is the biggest importer of materials from Latin America. (v) The price received for exported material is much lower than the price paid for imported material; and (vi) various historical periods can be differentiated regarding the relationship between economic growth and physical trade balance

The impacts of agricultural and urban land-use changes on plant and bird biodiversity in Costa Rica (1986-2014)

Costa Rica is recognized worldwide for its nature conservation policy following the traditional land-sparing approach. However, concerns have been raised about the opposite trends of the agricultural land cover changes driven by the option to expand old and new export crops after the country's external debt crisis of the 1980s. We study what happened during the last 20 years by applying landscape ecology metrics to the REDD+ land cover maps of 1986, 2001, and 2014, and statistically testing these indicators with the locations of species richness of plants and birds recorded by INBio. Our results confirm that deforestation has been reversed and most of the biodiversity considered is housed in forestland, but also that the expansion of export monocultures and urban sprawl have fragmented and isolated these tropical forests. Ecological connectivity values decreased 13% across the territory, all crops are negatively correlated with bird and plant locations, and the metropolitan expansion caused a detrimental impact on coffee agroforestry. All these outcomes are consistent with the growing deficit of the Costa Rican physical trade balance due to a faster increase of tropical exports than the growing imports of staple food, with a loss of soil organic matter filled by high doses of agrochemicals imported. Overcoming these environmental problems require a new land-sharing approach to nature conservation aimed at improving ecological connectivity through an agroecology approach combined with land-use planning to preserve the remaining green belt of the shade coffee plantations as a buffer green infrastructure in the metropolitan area

Unequal raw material exchange between and within countries:Galicia (NW Spain) as a core-periphery economy

Abstract A global multi-regional input-output model with sub-national resolution for Galicia, north-west Spain, was used to study physical and value added trade balances between Galicia, the rest of Spain and the world. Within the framework of Ecologically Unequal Exchange theory, we argue that a region, such as Galicia, can play a twofold role as core and periphery in the global division of extractive activities. We show that Galicia is a sink, i.e. net importer of natural resources from middle- and low-income economies, and that the lower the income of the trade partner, the more raw material intensive the imports (measured as upstream kg per USD imported value added). However, this physical deficit is less accentuated than for the rest of Spain and Galicia’s material footprint is significantly lower (~14.2 compared with ~24.5 t/capita). Moreover, Galicia is a source, i.e. net exporter of raw materials compared with more thriving European Union economies and, even for some key trade partners, such as Germany, UK and the rest of Spain, it is a net importer of value added

Make EU trade with Brazil sustainable

Brazil, home to one of the planet's last great forests, is currently in trade negotiations with its second largest trading partner, the European Union (EU). We urge the EU to seize this critical opportunity to ensure that Brazil protects human rights and the environment
