“…Although other studies on roadkill, especially those set in the Neotropics (e.g., Coelho et al, 2012;Freitas et al, 2010;Teixeira, Coelho, Esperandio, Rosa Oliveira, et al, 2013), might allow us to derive some generalities, we do not have any actual data on roadkill in the western Amazon, the part of the Amazon where human encroachment through road expansion is highest (Lessmann, Fajardo, Muñoz, & Bonaccorso, 2016;Mena, Lasso, Martinez, & Sampedro, 2017). To provide such initial data, and to start a body of literature which may aid the effective implementation of roadkill mitigation efforts in this biodiverse part of the world, we quantified roadkill incidents on two roads in the Ecuadorean Amazon.…”

One of the most evident and direct effects of roads on wildlife is the death of animals by vehicle collision. Understanding the spatial patterns behind roadkill helps to plan mitigation measures to reduce the impacts of roads on animal populations. However, although roadkill patterns have been extensively studied in temperate zones, the potential impacts of roads on wildlife in the Neotropics have received less attention and are particularly poorly understood in the Western Amazon. Here, we present the results of a study on roadkill in the Amazon region of Ecuador; a region that is affected by a rapidly increasing development of road infrastructure. Over the course of 50 days, in the wet season between September and November 2017, we searched for road‐killed vertebrates on 15.9 km of roads near the city of Tena, Napo province, for a total of 1,590 surveyed kilometers. We recorded 593 dead specimens, predominantly reptiles (237 specimens, 40%) and amphibians (190, 32%), with birds (102, 17%) and mammals (64, 11%) being less common. Recorded species were assigned to three functional groups, based on their movement behavior and habitat use (“slow,” “intermediate,” and “fast”). Using Ripley's K statistical analyses and 2D HotSpot Identification Analysis, we found multiple distinct spatial clusters or hotspots, where roadkill was particularly frequent. Factors that potentially determined these clusters, and the prevalence of roadkill along road segments in general, differed between functional groups, but often included land cover variables such as native forest and waterbodies, and road characteristics such as speed limit (i.e., positive effect on roadkill frequency). Our study, which provides a first summary of species that are commonly found as roadkill in this part of the Amazon region, contributes to a better understanding of the negative impacts of roads on wildlife and is an important first step toward conservation efforts to mitigate these impacts.

“…(3) The agricultural and extractive (hunting/fishing) frontier (Mena et al, 2017;Heredia-R and Hernández, 2019;Houssou et al, 2019) has advanced due to unsustainable agricultural activities (Heredia-R et al, 2020a,b,c), caused by a dependence on salaried jobs in the oil sector, according to the literature on the Dutch disease (Bozigar et al, 2016;Arsel et al, 2019;Erdogan et al, 2020), correlated with the majority of the EAR population being impoverished (Lang, 2017;Torres et al, 2017a), due to its externalities (Vasco et al, 2015). In addition, inequality in terms of sustainability in the groups evaluated is evidenced by the existence of new forms of land use and management, a greater use of land for planting cocoa, African palm species, and pastureland for cattle.…”

Although traditional agriculture carried out by ethnic groups is considered for its high biodiversity and important for food security and sovereignty, few studies have investigated the potential of these systems in the interest of promoting a sustainable agricultural development policy according to United Nations Sustainable Development Goals. Using the FAO's Sustainability Assessment of Food and Agriculture (SAFA) methodology, this study analyzed the sustainability of four traditional agricultural systems, three indigenous (Waorani, Shuar, and Kichwa) and one migrant settler populations in the Yasuní Biosphere Reserve (YBR) and identified synergies and trade-offs among the dimensions of sustainability. The results showed different dynamics in all dimensions of sustainability-specifically, trade-offs in the dimensions of good governance with environmental integrity and social well-being, economic resilience, and social well-being. It was identified that the differences in terms of sustainability are narrowing between the indigenous Shuar people's traditional agricultural systems and those of migrant settlers, which provides policymakers with specific information to design sustainable development policies and rescue traditional agricultural systems in the Amazon region.

“…An emergent and developing research agenda in land use science addresses the direct and indirect roles that energy geographies have on land use dynamics. Much of this research surrounds quantifiable energy sprawl, impacts, and intensity of production, using quantitative methods at a large scale, including work to measure energy potential of biomass production (Prade et al, 2017); map satellite data to demonstrate how bioenergy threatens food security (De Souza et al, 2017); and model deforestation as a result of oil exploration (Mena et al, 2017). Qualitative and mixed-method studies have focused on, for instance, socioeconomic, policy, and farm-level factors influencing sugarcane development and land-use change (Bergtold et al, 2017), or the social and political landscapes of industrial solar production (Mulvaney, 2017).…”

From a rural idyll to an industrial site: an analysis of hydraulic fracturing energy sprawl in Central Appalachia

This paper analyzes land-system dynamics changes due to energy infrastructure development and explores the environmental and social ramifications of hydraulic fracturing, through a case study in Central Appalachia. Grounded in photographic data, satellite images, and ethnographic material, this study demonstrates landscape and embodied experiences of change over time. Data show major shifts in terms of wildlife behavior, possibilities for farming and gardening, and byproducts of construction like noise, pollution, and excavation. However, what we argue is crucial to examine is the emotional toll that these changes have taken on rural residents. Interviewees chose to live in West Virginia because of deep enchantment with the surrounding natural beauty, which they feel they have lost due to energy development. While energy research has been dominated by technical disciplines and explanations, we advocate for an emotional-oriented analysis that accounts for individually lived experiences in the context of these landscape-level changes.
