The high Andean ecosystems in Peru constitute 14% of the surface of the territory at a national level and mining; the extractive activity of this area generates impacts in its exploration, exploitation, mineral processing and metallurgical processing activities considering the construction, operation and mine closure. Upon completion, it is a priority to recover the disturbed area and leave it in a state similar to that initially found. In the present investigation, the general objective was to identify the impacts of the mining activity that the " Humasha" Exploitation Project would generate in the stage of construction to the high Andean ecosystem, Pampa de Coshorococha, Huayllay-Pasco District, to implement a plan of management, with mitigation measures that counteract these impacts. The study was carried out through three stages: pre-field, field and cabinet; detailing that in t...

This article analyzes the fears and concerns many Venezuelan immigrants living in Peru go through every day. It delves into the communication dynamics between Peruvians and Venezuelans, as well as into its consequences at an intersubjective level. Methodologically, it is based on data gathered from interviews in Ayacucho, Chiclayo, Cusco and mainly in Lima. Basically, the life histories of immigrants in vulnerable situation are analyzed, whether they are unemployed, asking for financial support on the street or having undergone any difficult experience. Finally, the expectations they hold on the future are joined together, identifying a series of hopes they embrace to survive to the exploitation and discrimination they would face. However, this study still addresses the encouraging frameworks in a country that, as it is understood, is still an important migration destination for them.

This study presents a simplified analytical model for ore deposit evaluation for either an orebody in a stage of project or in actual exploitation. Model variables are average ore grades of contained metals, annual rate of ore mined and ore deposit reserves. The model estimates annual net cash income, return on investment and net value of the ore deposit at the investor’s fixed annual interest rate after discounting the total investment. An example of the model application is shown for a copper-zinc ore deposit mined by the open pit method. All three variables of the model are considered to be the most important factors and were chosen from a number of known variables of the annual income flow. The criteria for variables selection follow the 80/20 Pareto rule which shows that 20 percent of the factors account for 80 percent of the results. The surface mining method was chosen by compar...

Más del 70% de la Amazonía peruana está cubierta por parcelas de hidrocarburos para exploración y explotación. Estas parcelas se superponen a comunidades indígenas, áreas naturales protegidas y territorios reservados para poblaciones indígenas aisladas. El Proyecto de Gas Camisea (CGP), que es el mayor proyecto de exploración y explotación de gas en América Latina, ha estado operando desde 2000 en el sureste de la Amazonía del Cusco en Perú, en un territorio históricamente ocupado por las poblaciones indígenas de Machiguenga. Mi proyecto de investigación explora los impactos que las compañías externas de gas tienen en el estilo de vida de Machiguenga, con un enfoque particular en las mujeres. Realicé una investigación en la comunidad nativa de Machiguenga de Cashiriari, ubicada en la cuenca baja del Urubamba en la Amazonía del Cusco. El pueblo de Cashiriari se ve dir...

El Project Finance es un mecanismo de financiamiento alternativo al Corporate Finance que permite el financiamiento de grandes proyectos de infraestructura, sin necesidad de que las corporaciones pongan en riesgo su patrimonio y activos propios. A través del Project Finance se pueden ejecutar obras públicas de envergadura, en el marco de Contratos de Asociación Público Privada (APP), en donde la principal garantía de los Acreedores consistirá en el derecho que tiene la empresa que suscribe dicho contrato para explotar la infraestructura pública, bien sea a través del cobro de una tarifa a los Usuarios (en el caso de las APP Autosostenibles) o a través del cobro de un monto pre acordado con el Estado (en el caso de las APP Cofinanciadas). Para la estructuración exitosa de un Project Finance en una APP se requiere el trabajo conjunto de una serie de actores y de instrum...

Este estudio presenta un modelo analítico simplificado para valorar un yacimiento mineral en un proyecto de explotación o que se encuentra en explotación. Las variables que aparecen en el modelo son las leyes medias de los metales contenidos, el tonelaje anual de extracción mina y la reserva mineral del yacimiento. El modelo calcula el ingreso neto anual de efectivo y a una tasa anual de retorno fijado por el inversionista, calcula el valor neto del yacimiento después de descontar la inversión total. Se ejecuta una aplicación en un yacimiento de cobre-zinc. Las 3 variables que aparecen en el modelo fueron elegidas como las más importantes de un conjunto de factores que influyen en el flujo anual de fondos. El número de variables en el modelo sigue la ley de Pareto del 80/20 que establece que el 20 % de factores explican o representan el 80 % de la solución. Antes de elegir el m...

The era of Digital Customs is based on a paperless Customs due to the use of technologies to replace paper as a fundamental requirement to exercise its customs authority and offer a service with international standards. In other words, it is the change of mentality, progressively, of all the foreign trade operators that make up the logistics chain. This change began to be implemented since 2012 with the “Customs Dispatch System” (CDS) Project and to date has 3 components: SEIDA (Electronic System for the Exchange of Customs Documents): This allows the various operators to electronically transmit their different transactions. Operator Portal (Internet): Is an interoperability component between customs and foreign trade operators through the SOL key. Customs Officer Portal (Intranet): Where specialists, customs officers and unit heads interact with workflows and manage their operations...
