Abstract:
Abstract In the Ecuadorian Amazon—one of Earth’s last high-biodiversity wilderness areas and home to uncontacted indigenous populations—50 years of widespread oil development is jeopardizing biodiversity and feeding environmental conflicts. In 2019, a campaign to eliminate oil-related gas flaring, led by Amazonian communities impacted by fossil fuel production, resulted in an injunction against the Ecuadoran Ministry of Energy and Non-Renewable Natural Resources and the Ministry of Environment and Water. On 26 January 2021 the Court of Nueva Loja issued a historical order to ban gas flaring in the Ecuadorian Amazon. The present citizen science project played an important role in this process, enabling the production of independent spatial information through participatory mapping with indigenous and farmer communities. Globally, lack of independent information about oil activities has led to the monitoring of gas flaring by satellite imagery, achieving remarkable results. However, apart from institutional and remotely sensed data, reliable spatial information on gas flaring in the Ecuadorian Amazon is not available. Therefore, we adopted the community-based participatory action research approach to develop a participatory GIS process, aiming both to provide reliable data and to support social campaigns for environmental and climate justice. This work presents the first participatory mapping initiative of gas flaring at a regional scale, carried out completely through open source data and software. Having identified 295 previously unmapped gas flaring sites through participatory mapping, we highlight that the extent of gas flaring activities is well beyond the official data provided by the Ecuadorian Ministry of Environment and National Oceanic and Atmospheric Administration Nightfire annual datasets, which map only 24% and 33% of the sites, respectively. Seventy five of the detected sites were in the Yasuní Biosphere Reserve. Moreover, 39 of the identified sites were venting instead of flaring, a phenomenon never before documented in the Ecuadorian Amazon. This study demonstrates that, because official datasets and satellite imagery underestimate the extent of gas flaring in the Ecuadorian Amazon, community-based mapping offers a promising alternative for producing trusted, community-based scientific data. This community-produced data can support campaigns for legal recognition of human rights and environmental justice in the Ecuadorian Amazon. Finally, this study shows how local environmental conflicts can foster policy transformations that promote climate justice.

Abstract:
SummaryAmazona lilacina is a threatened species endemic to Ecuador, existing across a patchwork of mangroves, lowland coastal forests, agricultural and community owned land. The species was described in 2014 and listed as ‘Endangered’ on the IUCN Red List, however, full assessment of the population was lacking. Using a combination of field observations, roost surveys and community questionnaires, conducted over the last 20 years, we provide up-to-date information on the species’ Extent of Occurrence, estimate its global population size, and evaluate its level of threat. Our results suggest the species occurs across an area of 19,890 km2 in three distinct geographically isolated subpopulations. Roost surveys across the range estimate the minimum remaining population at 741–1,090 individuals and we present evidence to suggest a 60% decline over the past 19 years in one part of the species’ range. We conducted community questionnaires with 427 people from 52 communities. The presence of pet parrots was reported in 37 communities, including 17 communities which reported pet A. lilacina. From this we predict that over half of all communities within our study area keep parrots as pets and at least 96 communities keep A. lilacina. Our findings justify an IUCN Red Listing of at least ‘Endangered’ for this species and highlight the need for conservation support. In order to assess population health in more detail, further research is required to assess genetic diversity and roost dynamics, and to identify areas that may be important for feeding and nesting throughout the range. As many of these areas are likely to overlap with community owned land, we suggest that future conservation actions should revolve around, and be led by, these communities.

Abstract:
Two new species of the caddisfly genusCernotinaRoss, 1938 (Polycentropodidae) are described from the lowland Amazon basin of Ecuador,Cernotina tiputini, new species, andCernotina waorani, new species. These represent the first new species described from this region. We also record from Ecuador for the first timeCernotina hastilisFlint, previously known from Tobago, and present new Ecuadorian locality records forC.cygneaFlint, andC.lobisomemSantos & Nessimian. The homology of the intermediate appendage of the male genitalia of this genus is established. The region surveyed is under severe environmental threat from logging, mining, and crude oil extraction, making the description of the biodiversity of the region imperative.

Abstract:
Neoliberal reforms throughout Latin America are intended to promote development by opening up economies and encouraging market-oriented practices. These reforms have deeply affected the lives of indigenous peoples and their relationship with extralocal actors. Today, in the Ecuadorian Amazon, some indigenous peoples participate in oil-extraction negotiations, tourism, and intensive cattle ranching and agriculture as part of increased market integration. In the midst of these changes, questions about what ‘indigeneity’ means, both in integrating into and in resisting neoliberal reforms, are increasingly important for understanding social justice and environmental conservation issues in the Amazon region. The author explores how engagement with neoliberal practices and ways of knowing the world has opened up spaces for questioning fixed notions of indigenous identities and their role in representing, imagining, and developing indigenous alliances and rights claims in the Ecuadorian Amazon.

Abstract:
This paper explores the entanglement of dreams and reality in the production of economic infrastructures. It focuses on the Manta-Manaus multimodal transport corridor, which is currently being constructed between the Pacific coast of Ecuador and the Atlantic coast of Brazil, with the aim of integrating the Amazon into global production networks. Drawing on extensive field research conducted in Ecuador, we develop a fantastical materialism, as a theoretical and methodological approach to the intertwining of fantasy and materiality through which the spaces of capital are conceived, constructed, and brought to ruin. Manta-Manaus is revealed not only as a technocratic accumulation strategy, but also as a seductive dream of planetary integration and geographical freedom. This dream has become ensnarled in the material dynamics of uneven geographical development, and its infrastructures have been repurposed for the expansion of the oil frontier. The Real of Capital thus advances through the creative destruction of its own fantasies.

Full text
Abstract:
Anthropogenic activities performed in the Ecuadorian Amazon have released potentially toxic elements (PTEs) into the rivers, causing severe environmental pollution and increasing the risk of exposure to the residents of the surrounding areas. This study aims to carry out a human health risk assessment using deterministic and probabilistic methods to estimate the hazard index (HI) and total cancer risk (TCR) related to multi-pathway human exposure to PTEs in polluted rivers. Concentrations of Al, Cd, Cr, Cu, Hg, Ni, Pb, and Zn in surface water and sediment samples from rivers on the Ecuadorian Amazon were considered to assess the potential adverse human health effects. As a result, deterministic and probabilistic estimations of cancer and non-cancer risk through exposure to surface waters and sediments were above the safety limit. A sensitivity analysis identified the concentration of PTEs and the exposure duration (ED) as the two most important variables for probabilistic health risk assessment. The highest risk for receptors was related to exposure to polluted sediments through incidental ingestion and dermal contact routes. According to the deterministic estimation, the human health risk through ingestion of water was above the threshold in specific locations. This study reveals the potential health risk to which the population is exposed. This information can be used as a baseline to develop public strategies to reduce anthropogenic pollution and exposure to PTEs in Ecuadorian Amazon rivers.

Full text
Abstract:
The Western Amazon is a highly biodiverse area. Zooplankton diversity studies in the region have been primarily conducted in Peru and Colombia, with limited research in the Ecuadorian Amazon. To address this gap, our research aimed to enhance taxonomic knowledge and understand zooplankton diversity patterns in the Napo and Pastaza lower basins at different spatial and temporal scales. Two sampling expeditions were conducted in the high waters of 2021 and rising waters of 2022. Dry conditions in 2021 led to lower-than-expected water levels. The study identified 107 zooplankton species, revealing variations in richness and composition between years, lakes, and depth strata. Grande Lake, deeper and wider than Delfincocha, exhibited significant turnover variations across strata in both seasons. Despite a relative longitudinal homogenization between channels and floodplains during high waters, beta diversity across vertical and temporal gradients highlighted complex dynamic zooplankton communities in both lakes. In addition, we include the first records of 44 taxa for the Ecuadorian Amazon and 36 for Ecuador. These findings emphasize the need for targeted research and conservation efforts in the face of escalating environmental threats to the Western Amazon.

Abstract:
The region of the upper Cenepa river, in the Amazon region, was the scene of the last military confrontation between Ecuador and Peru. The Cenepa War (1995) was the last armed confrontation between the two countries throughout the 20th century. The Ecuadorian state lost significant portions of its territory in previous conflicts, suffering defeats in 1941 and 1981. The result in 1995 was different due to prior preparation and conduct of operations on the ground. This article raises how the conflict was portrayed in historiography by different authors, Ecuadorian, Peruvian and international.

Abstract:
This paper explores the possibilities and limitations of a post-neoliberal political project under conditions of planetary urbanization. We conceptualize planetary urbanization in terms of a tendency towards the real subsumption of space to capital on a global scale, through which capital is empowered as an abstract form of domination. We then relate this tendency to the ideology of ‘systemic competitiveness’ that has dominated the post-neoliberal project in Latin America, arguing that it threatens to strengthen the power of capital-as-subject. This relationship is illustrated by the Initiative for the Regional Infra-structural Integration of South America (IIRSA), and its incorporation into the post-neoliberal experiment currently underway in Ecuador. We focus on a series of IIRSA-related projects in the Ecuadorian Amazon, through which the real subsumption of space is disaggregated into three intertwined dimensions: territory, nature, and everyday life. In each case, we show how the ideological structure of post-neoliberalism unwittingly promotes the real subsumption of space and the empowerment of capital. However, the uneven dynamics of planetary urbanization imply that these projects are only succeeding in reproducing existing conditions of formal subsumption on an extended scale. The paper thus develops a materialist understanding of planetary urbanization in order to explain the failure of a political project to achieve its unintended results.

Abstract:
SUMMARYForest conservation incentives are a popular approach to combatting tropical deforestation. Here we consider a case where direct economic incentives for forest conservation were offered to newly titled smallholders in a buffer zone of a protected area in the northeastern Ecuadorian Amazon. We used quasi-experimental impact evaluation methods to estimate changes in forest cover for 63 smallholders enrolled in Ecuador's Socio Bosque program compared to similar households that did not enroll. Focus group interviews in 15 communities provided insight into why landowners enrolled in the program and how land use is changing. The conservation incentives program reduced average annual deforestation by 0.4–0.5% between 2011 and 2013 for those enrolled, representing as much as a 70% reduction in deforestation attributable to Socio Bosque. Focus group interviews suggested that some landowners chose to ‘invest’ in conservation because the agricultural capacity of their land was limited and economic incentives provided an alternative livelihood strategy. Interviews, however, indicated limits to increasing enrollment rates under current conditions, due to lack of trust and liquidity constraints. Overall, a hybrid public–private governance approach can lead to larger conservation outcomes than restrictions alone.

Abstract:
This article approaches livelihood alterations in Indigenous communities of the Ecuadorian Amazon as means of adaptation and resistance to socio-environmental impacts brought along by the expansion of global capitalism. The cases comprise collective Indigenous endeavors in typically capitalist sectors - tourism and mining - illustrated by the experiences of Kichwa community tourism in Shiripuno in the central Amazon, and sustainable mining in the southern Amazonian Shuar community of Congüime (Kenkuim). The aim is to unravel these emerging livelihood strategies in relation to Indigenous ethno-cultural identity. Methodologically, we rely on comparative and ethnographic work in the field with Indigenous actors, and on a theoretical framework anchored in the concepts of innovators, cultural boundary changes (Fredrik Barth), social fields of force (William Roseberry), and intercultural regimes (Fernando Galindo and Xavier Albó). In both empirical cases - Indigenous-controlled tourism and mining - communities are framing their ethnic identity to engage with, and positively reposition themselves in relation to the wider society. We hold that these endeavors must be comprehended as highly innovative, and that indigeneity and cultural boundaries can be strengthened by socio-cultural changes toward livelihoods previously considered as “unauthentic” or “non-Indigenous”. We also argue that these new livelihood orientations have (purposely) altered gender relations within the communities in benefit of women. Additionally, our cases suggest that cultural strengthening and gender empowerment, among other positive outcomes, requires a nuanced apprehension of indigeneity as a partly floating concept and instrument gaining ground amid the increasing interconnectedness of ancient traditions and capitalist modernity.

Full text
Abstract:
Tropical forests, and more concretely, the Amazon Basin and the Chocó-Darién, are highly affected by deforestation activities. Households are the main land-use decision-makers and are key agents for forest conservation and deforestation. Understanding the determinants of deforestation at the household level is critical for conservation policies and sustainable development. We explore the drivers of household deforestation decisions, focusing on the quality of the forest resources (timber volume potential) and the institutional environment (conservation strategies, titling, and governmental grants). Both aspects are hypothesized to influence deforestation, but there is little empirical evidence. We address the following questions: (i) Does timber availability attract more deforestation? (ii) Do conservation strategies (incentive-based programs in the Central Amazon and protected areas in the Chocó-Darién) influence deforestation decisions in household located outside the areas under conservation? (iii) Does the absence of titling increase the odds of a household to deforest? (iv) Can governmental grants for poverty alleviation help in the fight against deforestation? We estimated a logit model, where the dependent variable reflects whether or not a household cleared forest within the farm. As predictors, we included the above variables and controlled by household-specific characteristics. This study was conducted in the Central Amazon and the Chocó-Darién of Ecuador, two major deforestation fronts in the country. We found that timber volume potential is associated with a higher odds of deforesting in the Central Amazon, but with a lower odds in the Chocó-Darién. Although conservation strategies can influence household decisions, the effects are context-dependent. Households near the incentive-based program (Central Amazon) have a lower odds of deforesting, whereas households near a protected area (Chocó-Darién) showed the opposite effect. Titling is also important for deforestation reduction; more attention is needed in the Chocó-Darién where numerous households are living in untitled lands. Finally, governmental grants for poverty alleviation showed the potential to generate positive environmental outcomes.

Full text
Abstract:
Deforestation caused by gold mining in the Ecuadorian Amazon has increased by 300% in the last decade, leading to severe environmental degradation of water and land resources. Effective remediation and revegetation technologies are still needed to address this issue. This study aimed to foster revegetation on 0.5 hectares of degraded land in Naranjalito, a mining site in the Ecuadorian Amazon, by applying plant-based biocompost and biochar and planting Ochroma pyramidale and Arachis pintoi, two pioneer species. The project’s objective was to evaluate the impact of these treatments on vegetation cover recovery through physicochemical and microbiological improvements in the soil. Four blocks and sixteen experimental plots were established: eight plots received treatments with varying doses of biocompost+biol (BIOC), four plots included plantations without biocompost (Not-BIOC), and four served as control plots (bare land). Over six months, dasometric characteristics of O. pyramidale and the expansion of A. pintoi were recorded. The data were analyzed using multivariate methods. The results revealed significant differences between treatments, with BIOC plots T4 and T1 showing greater improvements in vegetation development compared to Not-BIOC plots T3 and T2, confirming the positive influence of biocompost+biol. The BIOC treatment favored not only the planted species but also the secondary successional plant communities including certain grasses, leguminous plants, and other shrub and tree species, thus accelerating the revegetation process. This study demonstrates that biocompost application is an effective strategy to enhance plant recolonization on land severely degraded by gold mining in the Ecuadorian Amazon.

Abstract:
This is the first report demonstrating that Boana tetete and B. maculateralis occur in the Colombian Amazon Basin. These specimens were identified previously as Boana fasciata; however, morphology and current distribution records show that the specimens were misidentified. These new records extend the known distribution of the B. tetete 630 km north from nearest locality in the Ecuadorian Amazon and 420 km for B. maculateralis. An updated map of current distribution and ecoregional areas in Amazonian is provided.

Abstract:
The effect of the addition of eCG on day 14 after FTAI was evaluated in 200 cows from the Ecuadorian Amazon, with a calf at the foot, of Brown Swiss breeds and their crosses (Bos indicus). Two treatments (T): T1 (J-Synch + eCG day 6) and T2 (J-Synch + eCG day 14 post-FTAI). The pregnancy rate for T1 (57%) and T2 (48%) without showing a significant difference (p≥0.05). The pregnancy percentage was higher (62.5%) in cows in estrus (125/200). Plasma progesterone levels differ between T1 and T2, evaluated on day 14: (7.1 ng/mL); (13.5 ng/mL), respectively, as well as on day 30: T1 (9.6 ng/mL) and T2 (13.7 ng/mL), (p≤0.05). The diameter of CL measured on day 14 (20.8 ± 3.3 mm) and day 30 (28.2 ± 6.2 mm) differed significantly (p≤0.05). Estrous expression is positively associated with an increased pregnancy rate, but improving eCG on day 14 post-FTAI does not improve the pregnancy rate in Ecuadorian Amazon cows.

Abstract:
We present the first Ecuadorian records of Furipterus horrens (Cuvier, 1828) from outside the Amazon Rainforest. Our specimens, collected in the Río Manduriacu Reserve, Imbabura Province, is the first record of any individual from the family Furipteridae in the Ecuadorian Andes. The genetic divergences observed with cyt-b and COI markers (10–15%) support previous studies that F. horrens represents a species complex and that the western Ecuador population may represent an undescribed species. This represents a significant increase in the potential habitat for this species and highlights the need for increased research into tropical Andean bat taxonomy.

Abstract:
(1) background: Urban representations of the Amazon are urgently needed in order to better understand the complexity of urban processes in this area of the World. So far, limited work that represents Amazonian urban regions has been carried out. (2) methods: Our study area is the Ecuadorian Amazon. We performed a K-means algorithm using six urban indicators: Urban fractal dimension, number of paved streets, urban radiant intensity (luminosity), and distances to the closest new deforested areas, to oil pollution sources, and to mining pollution sources. We also carried out fieldwork to qualitatively validate our geospatial and statistical analyses. (3) results: We generated six Amazonian urban regions representing different urban configurations and processes of major cities, small cities, and emerging urban zones. The Amazonian urban regions generated represent the urban systems of the Ecuadorian Amazon at a general scale, and correspond to the urban realities at a local scale. (4) conclusions: An Amazonian urban region is understood as a set of urban zones that are dispersed and share common urban characteristics such a similar distance to oil pollution sources or similar urban radiant intensity. Our regionalization model represents the complexity of the Amazonian urban systems, and the applied methodology could be transferred to other Amazonian countries.

"Five Underutilized Ecuadorian Fruits and Their Bioactive Potential as Functional Foods and in Metabolic Syndrome: A Review." Molecules 29, no. 12 (2024): 2904. http://dx.doi.org/10.3390/molecules29122904.

Full text
Abstract:
The Ecuadorian Amazon harbors numerous wild and cultivated species used as food, many of which are underutilized. This review explores the bioactive potential of five such fruits—Borojó (Alibertia patinoi); Chonta (Bactris gasipaes); Arazá (Eugenia stipitata); Amazon grape (Pourouma cecropiifolia), a wild edible plant; and Cocona (Solanum sessiliflorum)—and their applications against metabolic syndrome. This study highlights their health-promoting ingredients and validates traditional medicinal properties, emphasizing their significance in improving health and mitigating the effects of the Western diet. These fruits, integral to Ecuadorian cuisine, are consumed fresh and processed. Chonta is widely cultivated but less prominent than in pre-Hispanic times, Borojó is known for its aphrodisiac properties, Cocona is traditional in northern provinces, Arazá is economically significant in food products, and Amazon grape is the least utilized and researched. The fruits are rich in phenolics (A. patinoi, E. stipitata) and carotenoids (B. gasipaes, E. stipitata), which are beneficial in controlling metabolic syndrome. This study advocates for more research and product development, especially for lesser-known species with high phenolic and anthocyanin content. This research underscores the economic, cultural, and nutritional value of these fruits, promoting their integration into modern diets and contributing to sustainable agriculture, cultural preservation, and public health through functional foods and nutraceuticals.

Abstract:
The Ecuadorian Amazon is home to a rich biodiversity of woody plant species. Nonetheless, their conservation remains difficult, as some areas remain poorly explored and lack georeferenced records. Therefore, the current study aims predominantly to analyze the collection patterns of timber species in the Amazon lowlands of Ecuador and to evaluate the conservation coverage of these species in protected areas. Furthermore, we try to determine the conservation category of the species according to the criteria of the IUCN Red List. We identified that one third of the timber species in the study area was concentrated in three provinces due to historical botanical expeditions. However, a worrying 22.0% of the species had less than five records of presence, and 29.9% had less than ten records, indicating a possible underestimation of their presence. In addition, almost half of the species evaluated were unprotected, exposing them to deforestation risks and threats. To improve knowledge and conservation of forest biodiversity in the Ecuadorian Amazon, it is recommended to perform new botanical samplings in little-explored areas and digitize data in national herbaria. It is critical to implement automated assessments of the conservation status of species with insufficient data. In addition, it is suggested to use species distribution models to identify optimal areas for forest restoration initiatives. Effective communication of results and collaboration between scientists, governments, and local communities are key to the protection and sustainable management of forest biodiversity in the Amazon region.

Abstract:
Agroforestry systems in the Ecuadorian Amazon play a vital role in environmental conservation and the promotion of sustainable agriculture. Therefore, it is crucial to demonstrate the benefits of the associated species within these production systems. This study aimed to assess the impact of agroforestry systems on cocoa yield, carbon sequestration, earthworm presence, and the nutritional contribution of companion species linked to cocoa (Theobroma cacao L.) cultivation under agroforestry systems. The research was conducted at INIAP’s Central Experimental Station of the Amazon using a randomized complete block design with three replications. The agroforestry arrangements were: (1) monoculture; (2) forest (Cedrelinga cateniformis Ducke); (3) fruit forest (Bactris gasipaes Kunth); (4) service (Erythrina poeppigiana (Walp.) O.F.Cook); and (5) forest + service (E. poeppigiana + C. cateniformis). The results indicated that agroforestry systems showed better results than the monoculture in terms of yield (532.0 kg ha−1 compared to 435.4 kg ha−1) and total stored carbon (33.0–42.0 t ha−1 compared to 39.6 t ha−1). Additionally, agroforestry systems provided higher levels of Mg, B, and Ca, contributing to both crop yield and the presence of earthworms. These findings suggest a positive influence of companion species, improving soil nutrition through biomass incorporation and promoting environmental benefits (carbon sequestration). Therefore, agroforestry systems will support sustainable cocoa production in the Ecuadorian Amazon.

Abstract:
INTRODUCTION. The present investigation analyzes the elements that explain the failure of the undertakings carried out in the Ecuadorian Amazon. OBJECTIVE. The main objective of the study is to determine the socioeconomic factors that are difficult for the development of productive processes in the Amazonian indigenous communities, taking as a case study the community of Limoncocha. METHOD. Being a descriptive case study, qualitative research techniques were used 6 in-depth interviews with key actors and a focus group with 23 young people from the community. RESULTS. The analysis of the data obtained can be systematized in three determining aspects that hinder the development of community projects and sustainable undertakings over time: internal conflicts among the main leaders, educational system not oriented to entrepreneurship and the presence of inconclusive entrepreneurships. DISCUSSION AND CONCLUSIONS. In conclusion, it is argued that the absence of entrepreneurship culture, derived from a relationship of historical economic dependence with different public and private institutions, has given rise to the current scenario, where the community perceives itself as incapable of developing, managing and sustain community projects of a productive nature.

Abstract:
During the past decade, Ecuador’s Alianza PAÍS socialist government, primarily under the leadership of Rafael Correa, was committed to moving toward a post-neoliberal economy and implementing a “New Amazon” free of poverty, with expanded infrastructure and services, as part of the redistribution of oil revenues. However, in sites of state development projects, gender hierarchies and territorial dispossession in fact became more acute. Analysis of two place-based indigenous political ecologies—one in the central Amazon, where the state licensed new oil blocks in Sapara territory to a Chinese company in 2016, and the other in the Kichwa community of Playas de Cuyabeno in the northern Amazon, where the state company PetroAmazonas has operated since the 1970s—shows how women have reconfigured their ethnic and gender identities in relation to oil companies and the state in the context of rising and falling oil prices and in doing so reinforced or challenged male leaders’ positions in the internal structures of their communities and organizations. Durante la última década, el gobierno socialista de Alianza PAÍS de Ecuador, principalmente bajo el liderazgo de Rafael Correa, se comprometió a avanzar hacia una economía posneoliberal e implementar una “Nueva Amazonía” libre de pobreza, con infraestructura y servicios ampliados, como parte de la redistribución de los ingresos petroleros. Sin embargo, en los sitios de proyectos estatales de desarrollo, las jerarquías de género y el despojo territorial de hecho se hicieron más agudos. Análisis de dos ecologías políticas indígenas basadas en el lugar—una en la Amazonía central, donde el estado otorgó licencias de nuevos bloques petroleros en el territorio de Sapara a una compañía china en 2016, y la otra en la comunidad Kichwa de Playas de Cuyabeno, en el norte de la Amazonía, donde la compañía estatal PetroAmazonas ha operado desde la década de 1970—muestra cómo las mujeres han reconfigurado sus identidades étnicas y de género en relación con las compañías petroleras y el estado en el contexto del alza y la caída de los precios del petróleo y, al hacerlo, refuerzan o desafían las posiciones de los líderes masculinos en la estructura interna de sus comunidades y organizaciones.
