Gold extraction via small scale mining in the Amazon rainforest of Peru has become one of the greatest threats to deforestation and land degradation in the Amazon, especially in the Madre de Dios region which is one of the last biggest remnants of continuous tropical rainforest in the world. Restoration of these degraded ecosystems have become a priority in the last decade but without concrete actions, however, few research has been conducted in response to these restoration activities nor natural regeneration. The significance of this research was to 1) To Analyze how gold mining affects forest structure, species richness and diversity in the Amazon Rainforest of Madre de Dios, Peru. 2) To assess variation on diversity levels in secondary successional forest compared to that found in primary forest 3) to identify variations in the gold extraction methods reported in the region and how i...

This study evaluated risk factors associated with asymptomatic malaria among adults in communities near Iquitos: Zungarococha, Puerto Almendra, Ninarumi, and Llanchama. The sample consisted of 412 adults enrolled in a previous study conducted in 2017. The techniques used were a database review and standardized PCR and ELISA tests, and the instruments were a data collection form and a results processing form. The study found a prevalence of 10.2% of asymptomatic malaria, 4 times (16.5%) more cases of malaria were detected by PCR, 64.7% of submicroscopic cases were asymptomatic, and 97.6% of asymptomatic malaria cases were caused by Plasmodium vivax. The sociodemographic factors associated with the risk of asymptomatic malaria were living in Llanchama (OR 3.5, p<0.001, 95% CI 1.776–6.995) and being a laborer (OR 4.2, p=0.021, 95% CI 1.241–14.363). The epidemiological factors associated...

Las actividades humanas están produciendo un exceso de gases de efecto invernadero que están potencialmente calentando el clima de la tierra. En tanto que los ecosistemas forestales están almacenando el Carbono de la atmósfera en la biomasa y el suelo. La siguiente investigación, “Evaluación del incremento volumétrico de cinco especies forestales y su almacenamiento de captura de carbono, Centro de Producción e Investigación Pabloyacu, Moyobamba – 2018”, tuvo como objetivo general la evaluación del incremento volumétrico de cinco especies forestales y su almacenamiento de captura de carbono; Eucalipto torrelliana, Eucalipto saligna, Bolaina, Pino chuncho y Tornillo, especies encontradas, en la plantación forestal perteneciente al Centro de Investigación se desarrolló metodológicamente en dos fases, la fase de campo, que se desarrolló por etapas, la etapa de identifi...

The Regional Government of Cajamarca started in 2014 the recognition process as a regional conservation area of ​​the El Chaupe, Cunia and Chinchiquilla Forests. The objective of this study was to estimate the social benefits and costs for the establishment of the conservation area, which will serve the regional authority to manage its creation. In order to achieve the objective, a contingent valuation study was carried out in order to estimate the economic value of the main services provided by forests, after which, these values ​​were added to infer the social benefits they generate in a scenario of improvements through conservation programs. In addition, the probable costs of the optimal management of the area in which installation and program costs with long-term vision are included were estimated. The investigation concludes that the net social benefits range between 25 and ...
