Mining is one of the oldest economic activities of mankind. Within this activity, artisanal and small-scale gold mining (ASGM) is one of the most studied sectors due to its high level of environmental contamination and the social problems it causes. In recent years, ASGM in the northern Amazon of Ecuador has increased significantly, and studies that describe its current situation and impact are scarce. In this sense, the present study aimed to analyze the current status and socioenvironmental impacts caused by ASGM gold mining activities in the Cascales canton in the province of Sucumbíos in northeastern Ecuador. The methodological tools used in the present study were a literature review of scientific and gray literature, field visits to assess perceived impacts and an expert judgment to discuss the results and establish challenges. The main results indicate that illegal and informal activities continue to be carried out in the upper zone of the Cascales and Duvino rivers; 90% of local miners still use mercury in this activity, although it is legally prohibited. Among the main impacts evidenced are the contamination of water bodies, soil and atmosphere due to the use of mercury and disturbance to flora and fauna due to the use of machinery in the exploration process. Finally, the government should focus efforts on strengthening public policies to socialize the importance of good environmental practices in ASGM and the effects of the impacts on human health and environmental issues, all this with the support of social actors, such as ministries, universities, NGOs, ASGM associations and private enterprise.

Conflicts and ecological impacts in natural protected areas can arise for various reasons. The behavior of social stakeholders in the face of conflict is the object of study. Their reactions can be varied according to the personal interests of the parties. Conflicts can cause changes in the communities, incomprehensibly affecting the environment and ultimately transforming their lives. Although the environmental impacts have generally been well studied in protected areas, after reviewing the literature, it was observed that very few studies exist on the local economic conflicts that frequently arise. The purpose of this study was to evaluate the socio-ecological conflicts and impacts generated by the filming of the American reality series Naked and Afraid, produced by the Discovery Channel in the Ecuadorian Amazon-a special case in the Cuyabeno Wildlife Reserve. The data was gathered from numerous primary sources, including field interviews with the regional stakeholders involved and a video analysis of the Discovery Channels' Naked and Afraid. The results of our study conclude several interesting insights into various social and ecological conflicts and their resulting impacts on the Cuyabeno Wildlife Reserve. The first of these concerns the high impacts mainly associated with biotic components in the Reserve. The second set of interesting findings are social conflicts that were caused by the discontent of the Indigenous communities in relation to royalties and compensations left by the filming.

Ecuador belongs to the group of 17 megadiverse countries on the planet, and the Ecuadorian national system of protected areas covers around 20% of the country’s territory. Despite some initiatives for protected areas management effectiveness evaluation, the information on this matter is scarce and a general overview is missing. In this context, this study aims at investigating problems faced by National Parks in Ecuador and developing a base level management effectiveness evaluation for possible comparative assessments in the future. Focusing on all 12 legally established National Parks, this study used the Management Effectiveness Tracking Tool (METT), an internationally consecrated methodology based on a scorecard questionnaire that includes six elements of management cycle: context, planning, inputs, processes, outputs and outcomes. The questionnaire was applied to Ecuadorian National Parks management teams through face-to-face interviews. The resulted overall management effectiveness indices are between 40.6% and 99.0%. The general condition of biodiversity value was considered as good in line with the legal status and National Parks design but topics related to budget allocation, tourism arrangements, communities and indigenous people received lower scores. The low enforcement emphasis is not necessarily the best way to improve management effectiveness; the identified issues should be addressed by including communities and indigenous people in the decision making and benefits sharing as well as strategic allocation of budgetary resources, with proper adaptation to Natural Parks’ specific conditions.

At present, climate change is a direct threat to biodiversity and its effects are evidenced by an increasingly accelerated loss of biodiversity. This study identified the main threats presently facing the Tapirus pinchaque species in Ecuador, generated predictive models regarding its distribution, and analyzed the protected areas as a conservation tool. The methodology was based on a literature review and the application of binary predictive models to achieve these objectives. The main results indicate that the T. pinchaque is seriously threatened, mainly by changes in land use. In addition, three models were selected that show current and future suitable areas for the conservation of the species. Its current distribution amounts to 67,805 km2, 33% (22,872 km2) of which is located in 31 of the 61 protected areas. Finally, it is important to take timely actions focused on biodiversity conservation, considering the importance of balance in ecosystems to the humans dependent thereof, and the results regarding the changes in the current and future distribution areas of the mountain tapir are a great contribution to be used as a management tool for its conservation.
