“…Despite the observed land use changes [74], the respondents did not perceive deforestation as a significant risk for them unless it was associated with colonists' claiming the land for agricultural purposes [24,45]. Land rights and the lack of significant community benefits from using their land for oil activity are of great concern for the community members, as reported by Gilbert [75].…”

Protected areas are considered the backbone of biodiversity conservation, but their management often fails because local people are not involved, and their needs are ignored. A socioecological approach has been demonstrated to be effective in improving the relationship between conservation efforts and human wellbeing through a better understanding of the interdependence between nature and people. This relationship can be observed through the case of the Kichwa indigenous communities within Yasuní National Park, Ecuador, as they have retained a very close relationship with forest ecosystems. Using key respondent interviews, along with semi-structured interviews and focus groups, this research describes the complex relationship between changing forest ecosystems and human wellbeing. The results highlight food, health, and cultural identity as the most important benefits that communities obtain from forests. The research also sheds light on how people in the investigated area perceive the dynamics of socioecological systems, indicating petroleum, infrastructure development, and small-scale agriculture as the most important direct drivers and land governance and the presence of colonists as the most important indirect drivers of changes to forest ecosystems. This paper demonstrates the importance of monitoring socioecological systems and adapting management to balance complex economic, social, and ecological challenges.

“…Donde encontramos valores negativos en las categorías de suelo desnudo con -7,5%, seguido de bosque denso con -1,7% y cuerpos de agua con -1,2%. A partir del año 2001 la superficie forestal ha venido disminuyendo, solo las áreas de infraestructura y agricultura han aumentado hasta 2017, según un estudio empleado en el bloque petrolero ITT (bloque 43) efectuada por (Heredia et al, 2021).…”

El propósito de este estudio es analizar la pérdida de cobertura vegetal y los cambios en el uso del suelo durante el período 2001-2020. Metodológicamente la investigación fue de tipo documental, se obtuvo información de las bases de datos SciELO, difusión de alertas en la red Dialnet entre otros. Los resultados evidenciaron que las ganancias y pérdidas de superficie original, para la categoría de bosque denso se demostró mayores pérdidas para el año 2020, a diferencia de las ganancias, gran parte de las pérdidas de bosque se dieron para usos agrícolas y ganaderos. En conclusión, la frontera de pastos y cultivos se incrementaron para el año 2020; se prevé que esta tendencia de cambio continuará hasta el 2040, en mayor proporción para la categoría de pastos y cultivos, esto representa que existirán problemas de biodiversidad de servicios ambientales y sociales, debido a que no se han formulado políticas claras.

“…FAO stated that between 1990 and 2000, Ecuador had the highest deforestation rate, averaging 1.2% year. Consequently, these factors have led to a land-use change, and fragmentation of farms due to population growth (Mena et al, 2006;Heredia-R et al, 2021). Since, Botto-Nuñez et al (2020) found association between forest fragmentation and pathogen spillover by contact with reservoir species (e.g., bats).…”

The hematophagous bats are usually the main reservoir of sylvatic rabies, being one of the most important viral zoonoses affecting humans and livestock in Latin America. Despite the most countries have already studied spatio-temporal distribution of bovine rabies, however, in Ecuador, little has been reported about the state of rabies in the country. Aiming to this objective, a descriptive observational study was realized from 2007 to 2020 based on the formal reports by WAHI-OIE and surveillance of bovine rabies retrieved from its official website. During the study period in Ecuador, some 895 cases of rabies were confirmed in cattle. In addition, in the total of bovine rabies cases seen in Andean and Coast regions (185 effected bovines), Loja and Esmeraldas had 95 (6.16% cases per 10,000 animals) and 51 (1.7% cases per 10,000 animals), respectively. Furthermore, the Amazon region indicated higher rabies cases in cattle than to the observed in other regions (710 rabies cases) while it was highly fluctuating with respect to the years (9.74 to 42.82% cases per 10,000 animals). However, Zamora (292 rabies cases), Orellana (115 rabies cases) and Sucumbíos (113 rabies cases) yielded the highest incidence rates than other provinces (9 to 42% cases per 10,000 animals). Based on this evidence, it has been fundamental to assess the current national program for preventing and control of the sylvatic rabies, being also necessary to include concept of the ecology of the vampire bat. Regardless of these results, vaccination is vital for control programs to prevent rabies in livestock and need to be widely increased for limiting their geographic and temporal spread.
