Linking National Agrarian Policy to Deforestation in the Peruvian Amazon: A Case Study of Tambopata, 1986–1997

The present work corresponds to five different case studies of peasant agriculture and of 2 social types: one Amazonian and the other Andean immigrant, located in four different ecological floors. It was carried out in the Pilluana and Three United districts, Picota province, San Martín department, Upper Amazon of Peru. Open and semi-structured interviews were conducted and, direct observations of the various activities that exist in each family property with tours of each of the plots that it has on its properties in order to record in-situ information regarding the diversity they conserve, the uses and destinations of this diversity, concentrating on the value of diversity that is market oriented; it was analyzed on the basis of diversified production data, production volumes, values for each of them, environmental values, and food security and sovereignty; noting their resilience, adaptation and mitigation to the disorders of the contexts that present themselves.

Multiple Variables

Complexity in the management and variability of environmental factors in the agricultural, environmental and food industries has brought about the demand for developing robust methods that allow multiple variables to operate with compound dependencies and are inert to changing situation conditions (e.g. changing the agrarian policy of the state). Therefore, new attempts are being made to cope with these problems (i.e. complexity in control and the instability of initial conditions). There is one solution based on interdisciplinary or transdisciplinary approaches; these methods were chosen for our case study on the agribusiness sector, where we use economic variables in the transformed form. This transformation allowed us to determine the optimal parameter settings (regarding factor instability) and the potential for regulating agribusiness activities using the corporate cybernetic diagrams. Estimations of the position and variability of the input values of the factors were carried out using a random vector. The practical experiment was conducted on the Agro-farm Krasna as a case study, thereby making it easy to repeat the designed procedure.

: La Amazonia occidental, puntualmente la región de Madre de Dios, es conocida como la capital de la biodiversidad del Perú y es reconocida mundialmente como uno de los lugares con mayor biodiversidad de la Tierra. Sin embargo, se ha visto amenazada por un grave problema de pérdida de bosques. Las principales amenazas ambientales se deben a una mala gestión del territorio que ocasionan la concentración de tierras, expansión agrícola, ganadería, minería de oro y la explotación económica descontrolada. El presente estudio analiza la dinámica de pérdida de bosques y los cambios de uso de suelo entre 1999-2018. Para la cuantificación de la pérdida de bosque se utilizaron técnicas de sensoramiento remoto, imágenes Landsat 5 Thematic Mapper (TM) y 8 Operational Land Imagery (OLI). Las imágenes fueron procesadas utilizando una clasificación supervisada denominada Neural Net. La metodología incluye procedimientos de validación utilizando puntos de verificación de campo e imágenes de teledetección de media y alta resolución de diferentes sensores (SPOT-5, PlanetScope, WorldView y Drone). Los resultados mostraron una pérdida de bosque durante 1999-2018 de 1698.63 km2 , con una tasa anual de -0.21% y una pérdida promedio de 59.28 km2 /año. Para los cambios de bosques a otros usos de la tierra, encontramos la conversión 841.41 km2 durante 2014-2018. Nuestros resultados indican que la agricultura es la mayor responsable del avance de la deforestación (72.90%), mientras que la minería de oro tiene una mayor incidencia en los sectores focalizados.

Detailed Case

Abstract This paper investigates the role of negation in grammaticalization in Iquito, an endangered Zaparoan language of the Peruvian Amazon. Iquito has a verb, pajɨɨni, which has undergone two paths of grammaticalization only in negated clauses. First, pajɨɨni has grammaticalized from “learn” to “be able to.” Subsequently, it is undergoing grammaticalization from an ability verb to a future auxiliary. Given that ability verbs are an uncommon source for future auxiliaries (Bybee et al. 1994), this study provides a detailed case study of this rare path. Our analysis of Iquito demonstrates that grammaticalization paths are not limited to affirmative contexts and may behave differently depending on the polarity of the utterance.
