Impacts of hydropower on the habitat of jaguars and tigers

The rapid expansion of hydropower across tropical landscapes has caused extensive habitat loss and degradation, triggering biodiversity loss. Despite known risks to freshwater biodiversity, the flooding of terrestrial habitats caused by dam construction, and associated impacts on terrestrial biota, have been rarely considered. To help fill this knowledge gap, we quantified the habitat loss following inundation of hydropower reservoirs across the range of two iconic species, jaguars and tigers. To do so, we compiled existing and planned dams intersecting the distribution of these apex predators. We found 164 dams intersecting the jaguar range, in total flooding 25,397 km2. For tigers, we identified 421 dams, amounting to 13,750 km2. As hydropower infrastructure is projected to expand in the decades ahead, these values are expected to increase greatly, particularly within the distribution of jaguars where the number of dams will nearly quadruple (429 planned dams). Despite the relatively few dams (41) planned across the range of tigers, most will intersect priority conservation areas for this species. We recommend a more cautious pursuit of hydropower in topographically flat regions, to avoid extensive habitat flooding which has occurred in the Neotropics, and avoiding dam construction in priority conservation landscapes for tigers.

Assessing the contribution of mobility in the European Union to rubber expansion

Nearly three-quarters of global natural rubber production is used to produce tyres, supporting mobility around the globe. The projected increase in mobility could contribute to further expansion of rubber plantations and impact tropical ecosystems. We quantified the use of natural rubber in tyres in the European Union (EU), the corresponding land footprint, and explored drivers of tyre use using country-specific transport statistics and trade registers of rubber goods. Five percent of the world’s natural rubber is consumed in tyres used in the EU, using up to a quarter of the area under rubber plantations in some producing countries. Car use is responsible for 58% of this consumption, due to car-dependent lifestyles that are associated with economic prosperity and spatial planning paradigms. While the EU’s transport policy focuses on reducing dependence on fossil-fuels, cross-cutting policies are needed to address car-dependency and reduce the EU’s land footprint in tropical landscapes without compromising progress towards decarbonisation.

The Pluriversality of Efforts to Reduce Deforestation in Brazil over the Past Decade: An Analysis of Policy Actors’ Perceptions

Brazil offers a complex and unique example of tropical landscapes. The country has considerably decreased deforestation since 2004, but Reducing Emissions from Deforestation and Forest Degradation (REDD+) is arguably under question, both as a concept and as a tool to reduce greenhouse gas (GHG) emissions, as deforestation levels have increased over the last five years. This article investigates how different policy actors have perceived REDD+ over time, how they have engaged in REDD+ efforts over the past decade, and how REDD+ implementation in Brazil should move forward accordingly. We analyzed qualitative data from semi-structured interviews and actors’ “stances”, i.e., their positions—with regards to key issues connected to REDD+ governance and its challenges—over three different time periods (Phase 1: 2010–2011, Phase 2: 2015–2016, and Phase 3: 2019), so as to identify the practical implications of these diverse interpretations. We argue that the way actors perceive REDD+ is intimately related to the way they interpret and assign meanings towards it and, in consequence, the way they coordinate REDD+-related practices and efforts. We focus on the link between perceptions and efforts so as to comprehend the relevance that different interpretations have to both the concept and implementation of REDD+ in Brazil. Our analysis concentrates on the potential to improve the coordination and integration of REDD+ implementation and diverse actors’ efforts with regards to REDD+ activities. Results suggest that actors’ perceptions of REDD+ generated a plurality of meanings, highlighting a range of dialectical and ontological interactions that have, in turn, resulted in multiple REDD+ interpretations. Findings highlight that different actors have the same interests when it comes to their organizational efforts to reduce emissions from deforestation and forest degradation, suggesting that there is room for a better coordination of efforts towards this end, as well as increased collaboration.
