Caracterización y aprovechamiento de los varillales amazónicos : contribución a la economía de las comunidades locales

La Gestión Forestal Sustentable es la principal herramienta para garantizar la compatibilidad entre producción y conservación en todos los bosques, y mas especialmente en los que exhiben niveles máximos de diversidad, como los tropicales humedos. En ellos existe un gran desconocimiento sobre la gestión de los recursos maderables de pequeña dimensión y los no maderables (PFNM) con mercado local. La madera redonda de pequeño diámetro es un recurso forestal de bajo valor económico extraído tradicionalmente por los pobladores locales de las zonas tropicales húmedas para construir sus viviendas. Los fustes de mejor calidad se obtienen del bosque de varillal, o bosques sobre arena blanca, altamente oligotroficos, sin potencial agrícola, escasos, dispersos, de pequeña superficie, gran fragilidad y alto porcentaje de endemismos. En el entorno de los centros urbanos de la Amazonia peruana, esta madera supone uno de los principales ingresos económicos para la población local, al ser extraida para su comercialización en dichos centros urbanos. Esto supone un riesgo de sobre-explotacion cuyos efectos se desconocen hasta el momento. Para acercarnos la situacion ambiental, social y económica asociada al varillal, se han realizado inventarios botanicos y de estructura forestal, se ha descrito el sistema de aprovechamiento tradicional y cuantificado sus efectos y, finalmente, se han realizado encuestas orientadas a analizar la situación social y economica de las comunidades locales que extraen y comercializan sus productos. El aprovechamiento tradicional del varillal es una actividad de bajo impacto que no emplea maquinaria y se centra en la extracción de fustes con diámetro normal entre 5 y 15 cm y características especificas de longitud, forma de fuste y calidad de la especie. Los resultados ponen de manifiesto la relevancia de la distancia existente entre el punto de extracción y el punto de venta, asi como la gran influencia que tiene la situación social y económica en la gestión sustentable del varillal. Todo ello pone en evidencia que si existe un cierto efecto negativo de la extracción intensa y continuada que han sufrido los varíllales mas próximos al centro urbano. Para favorecer una Gestión Forestal Sustentable que reduzca este efecto negativo es esencial llevar a cabo una adecuada planificación comunal que permita establecer una secuencia ordenada de zonas de corta y un cronograma para su gestión y aprovechamiento que evite la extracción repetida en un mismo varillal. ABSTRACT Sustainable forest management is the main tool to ensure compatibility between production and conservation in all forests, and especially in those exhibiting the maximum levels of diversity, such as tropical rain. Within them there is a great ignorance about the management of small sized timber and non-timber resources (PFMN) in the local market. The small-diameter round timber is a forest resource of low economic value extracted traditionally by local people of the humid tropics to build their homes. The better quality shafts are obtained from varillal forest or forests on white sand, highly oligotrophic, no agricultural potential, few, scattered, small size, fragility and high percentage of endemic species. In the environment of the urban centres of the Peruvian Amazon, this wood is one of the main incomes for the local population, since it is extracted for marketing in these urban centres. This poses a risk of overexploitation whose effects are unknown so far. To approach the environmental, social and economic situation associated to the varillal, botanical and forest structure inventories have been conducted, traditional harvesting systems described and their effects quantified and targeted surveys have eventually been conducted to analyse the social and local economic situation of the communities that extract and sell the products. The traditional use of varillal is a low-impact activity that does not use machinery and focuses on the extraction of shafts with a normal diameter of between 5 and 15 cm and specific characteristics in length, stem form and quality of the species. The results highlight the importance of the distance from the extraction point and the sale point, and the great influence of the social and economic situation in the sustainable management of varillal. This demonstrates that there is indeed a negative effect caused by the intense and continuous extraction that varillales closest to the city centre have suffered. To encourage a Sustainable Forest Management to reduce this negative effect is essential to conduct proper community planning in order to establish an ordered sequence of areas and a chronogram for their management and use, to avoid a repeat extraction in the same varillal.

Planning and community development: case studies

Planning and Comunity Development: Case Studies, presents the findings of the inter-university Seminar held on 28?29 July 2011 and organized by researchers from the Technical University of Madrid and the University of California, Berkeley, who were fortunate to have the presence of the renowned Professor John Friedmann. Professors, researchers and PhD students from our research groups presented their works as scientific communications that were enriched by the debate among the different researches who attended the Seminar. All of them appear in the picture below in front of the gate of Haviland Hall at UC Berkeley. This book analyses the concept of planning and its evolution so far, leading to the conceptualization of governance as an expression of the planning practice. It also studies the role of social capital and cooperation as tools for the community development. The conceptual analysis is complemented by the development of six case studies that put forward experiences of planning and community development carried out in diverse social and cultural contexts of Latin-America, Europe and North America. This publication comes after more than 20 years of work of the researchers that met at the seminar. Through their work in managing development initiatives, they have learned lessons and have contribute to shape their own body of teaching that develops and analyses the role of planning in public domain to promote community development. This knowledge is synthesized in the model Planning as Working With People, that shows that development is not effective unless is promoted in continuous collaboration with all the actors involved in the process.

Advanced system of planning and organization of classes at the university

This document is the result of a process of web development to create a tool that will allow to Cracow University of Technology consult, create and manage timetables. The technologies chosen for this purpose are Apache Tomcat Server, My SQL Community Server, JDBC driver, Java Servlets and JSPs for the server side. The client part counts on Javascript, jQuery, AJAX and CSS technologies to perform the dynamism. The document will justify the choice of these technologies and will explain some development tools that help in the integration and development of all this elements: specifically, NetBeans IDE and MySQL workbench have been used as helpful tools. After explaining all the elements involved in the development of the web application, the architecture and the code developed are explained through UML diagrams. Some implementation details related to security are also deeper explained through sequence diagrams. As the source code of the application is provided, an installation manual has been developed to run the project. In addition, as the platform is intended to be a beta that will be grown, some unimplemented ideas for future development are also exposed. Finally, some annexes with important files and scripts related to the initiation of the platform are attached. This project started through an existing tool that needed to be expanded. The main purpose of the project along its development has focused on setting the roots for a whole new platform that will replace the existing one. For this goal, it has been needed to make a deep inspection on the existing web technologies: a web server and a SQL database had to be chosen. Although the alternatives were a lot, Java technology for the server was finally selected because of the big community backwards, the easiness of modelling the language through UML diagrams and the fact of being free license software. Apache Tomcat is the open source server that can use Java Servlet and JSP technology. Related to the SQL database, MySQL Community Server is the most popular open-source SQL Server, with a big community after and quite a lot of tools to manage the server. JDBC is the driver needed to put in contact Java and MySQL. Once we chose the technologies that would be part of the platform, the development process started. After a detailed explanation of the development environment installation, we used UML use case diagrams to set the main tasks of the platform; UML class diagrams served to establish the existing relations between the classes generated; the architecture of the platform was represented through UML deployment diagrams; and Enhanced entity–relationship (EER) model were used to define the tables of the database and their relationships. Apart from the previous diagrams, some implementation issues were explained to make a better understanding of the developed code - UML sequence diagrams helped to explain this. Once the whole platform was properly defined and developed, the performance of the application has been shown: it has been proved that with the current state of the code, the platform covers the use cases that were set as the main target. Nevertheless, some requisites needed for the proper working of the platform have been specified. As the project is aimed to be grown, some ideas that could not be added to this beta have been explained in order not to be missed for future development. Finally, some annexes containing important configuration issues for the platform have been added after proper explanation, as well as an installation guide that will let a new developer get the project ready. In addition to this document some other files related to the project are provided: - Javadoc. The Javadoc containing the information of every Java class created is necessary for a better understanding of the source code. - database_model.mwb. This file contains the model of the database for MySQL Workbench. This model allows, among other things, generate the MySQL script for the creation of the tables. - ScheduleManager.war. The WAR file that will allow loading the developed application into Tomcat Server without using NetBeans. - ScheduleManager.zip. The source code exported from NetBeans project containing all Java packages, JSPs, Javascript files and CSS files that are part of the platform. - config.properties. The configuration file to properly get the names and credentials to use the database, also explained in Annex II. Example of config.properties file. - db_init_script.sql. The SQL query to initiate the database explained in Annex III. SQL statements for MySQL initialization. RESUMEN. Este proyecto tiene como punto de partida la necesidad de evolución de una herramienta web existente. El propósito principal del proyecto durante su desarrollo se ha centrado en establecer las bases de una completamente nueva plataforma que reemplazará a la existente. Para lograr esto, ha sido necesario realizar una profunda inspección en las tecnologías web existentes: un servidor web y una base de datos SQL debían ser elegidos. Aunque existen muchas alternativas, la tecnología Java ha resultado ser elegida debido a la gran comunidad de desarrolladores que tiene detrás, además de la facilidad que proporciona este lenguaje a la hora de modelarlo usando diagramas UML. Tampoco hay que olvidar que es una tecnología de uso libre de licencia. Apache Tomcat es el servidor de código libre que permite emplear Java Servlets y JSPs para hacer uso de la tecnología de Java. Respecto a la base de datos SQL, el servidor más popular de código libre es MySQL, y cuenta también con una gran comunidad detrás y buenas herramientas de modelado, creación y gestión de la bases de datos. JDBC es el driver que va a permitir comunicar las aplicaciones Java con MySQL. Tras elegir las tecnologías que formarían parte de esta nueva plataforma, el proceso de desarrollo tiene comienzo. Tras una extensa explicación de la instalación del entorno de desarrollo, se han usado diagramas de caso de UML para establecer cuáles son los objetivos principales de la plataforma; los diagramas de clases nos permiten realizar una organización del código java desarrollado de modo que sean fácilmente entendibles las relaciones entre las diferentes clases. La arquitectura de la plataforma queda definida a través de diagramas de despliegue. Por último, diagramas EER van a definir las relaciones entre las tablas creadas en la base de datos. Aparte de estos diagramas, algunos detalles de implementación se van a justificar para tener una mejor comprensión del código desarrollado. Diagramas de secuencia ayudarán en estas explicaciones. Una vez que toda la plataforma haya quedad debidamente definida y desarrollada, se va a realizar una demostración de la misma: se demostrará cómo los objetivos generales han sido alcanzados con el desarrollo actual del proyecto. No obstante, algunos requisitos han sido aclarados para que la plataforma trabaje adecuadamente. Como la intención del proyecto es crecer (no es una versión final), algunas ideas que se han podido llevar acabo han quedado descritas de manera que no se pierdan. Por último, algunos anexos que contienen información importante acerca de la plataforma se han añadido tras la correspondiente explicación de su utilidad, así como una guía de instalación que va a permitir a un nuevo desarrollador tener el proyecto preparado. Junto a este documento, ficheros conteniendo el proyecto desarrollado quedan adjuntos. Estos ficheros son: - Documentación Javadoc. Contiene la información de las clases Java que han sido creadas. - database_model.mwb. Este fichero contiene el modelo de la base de datos para MySQL Workbench. Esto permite, entre otras cosas, generar el script de iniciación de la base de datos para la creación de las tablas. - ScheduleManager.war. El fichero WAR que permite desplegar la plataforma en un servidor Apache Tomcat. - ScheduleManager.zip. El código fuente exportado directamente del proyecto de Netbeans. Contiene todos los paquetes de Java generados, ficheros JSPs, Javascript y CSS que forman parte de la plataforma. - config.properties. Ejemplo del fichero de configuración que permite obtener los nombres de la base de datos - db_init_script.sql. Las consultas SQL necesarias para la creación de la base de datos.
