Apresento, neste ensaio (autora), um breve histórico sobre a questão agrícola na região do Monte Pascoal e a forma como os modos cotidianos de resistência Pataxó foram capazes de promover a perpetução de saberes e práticas agrícolas tradicionais de gestão da agrobiodiversidade em detrimento do avanço das mudanças ambientais e dos projetos de modernização dos sistemas agrícolas. Ainda, demonstro como esses modos de vida possibilitaram a adaptação de conceitos e práticas advindas de atores externos, como técnicos, ambientalistas e planejadores, inovando-os através de mecanismos próprios que a

 
COMPLEJAS CONJUNCIONES: CAMBIO CLIMÁTICO Y REPRIMARIZACIÓN DE LAS ECONOMÍAS
Karen Mercado Andia *
Hace pocos días, como salidas de algún filme, rondaban imágenes de Chicago con temperaturas extremas de bajo cero, recordándonos, pero esta vez de manera rotunda, los comentarios cotidianos de los cambios en el clima, entre ellos: el calor esta insoportable o este frío no lo habíamos sentido nunca, las lluvias se han retrasado y no podemos empezar la sembrar, la sequía es cada vez más larga… comentarios que estación tras estación se hacen más recurrentes.

Introducción​ constituyente
La situación actual por la que atraviesa el país da cuenta de temas pendientes, no solo en el ámbito político sino fundamentalmente constitucional.
Son tiempos de constituyente para cambiar una constitución que no llegó a su mayoría de edad. Nuestra carta magna con una cortísima historia de afecciones y desafecciones, hoy es amenazada de ser lanzada al cesto de la basura de la historia. Junto a ella todos los derechos reconocidos, entre otros, los de los pueblos indígenas.

For over a decade, the globalisation of environmental, economic and social issues has induced rapid modification in agriculture and land. These changes raise the question of future extensive livestock systems in regards to the worldwide challenge to double livestock production by 2050 in ways which are safe for the environment. In order to better understand and follow modification processes, a comparative study of livestock systems and land dynamics has been carried out on seven case studies on three continents through the use of a common grid.

We propose a flexible and adaptable framework to assist the quick design of models dealing with the durability of the extensive livestock systems at the territorial scale. This metamodel results from the collaborative design starting from MAS developed on 7 sites in Latin America, France and Senegal. It is composed of four packages: Agent, Community, Space and Vegetation-Herd. We illustrate these packages with examples extracted from the various models. The role of this tool is discussed in order to show its advantages and its limits

A combined agronomic and geographic approach has helped to explain forest agrosystem spatio-temporal dynamics in the forest regions of Guinea. The important expansion of cropping systems associating various perennial crops (coffee, kola, cocoa, fruit trees) and native spontaneous forest species – called “agroforests”- has been observed in 3 villages of the Kobela area. This spatial dynamic can be considered as the renewing of an ecosystem dominated in the past by forest.

Once the conditions that led to the creation of the Société Civile des Terres du Larzac (SCTL) have been introduced, the companion modelling approach used with this group of farmers is presented. The agent-based model co-constructed with a group of researchers and technicians is then described, as well as the way it was used to confront scenarios developed by the SCTL to envision management options of the forest massif, with scenarios developed by the farmers to improve the current functioning of their farms

Land degradation has been a major political issue in Java for decades. Its causes have generally been framed by narratives focussing on farmers’ unsustainable cultivation practices. This paper causally links land degradation with struggles over natural resources in Central Java. It presents a case study that was part of a research project combining remote sensing and political ecology to explore land use/cover change and its drivers in the catchment of the Segara Anakan lagoon.
