Resumen en español

Este libro describe la construcción de un estudio socioecológico participativo que explora formas para integrar a los actores locales y regionales en el proceso de toma de decisión y aprendizaje colectivo del manejo del bosque a partir de modelación acompañante. Se utiliza como ejemplo la resinación de Pinus oocarpa en dos ejidos de la Reserva de la Biósfera La Sepultura, Chiapas, México. El proyecto de resina combina la conservación de la biodiversidad y el desarrollo social de la población local. La viabilidad de este proyecto a largo plazo está en riesgo debido a la presencia de pastos exóticos que limitan el reclutamiento del pino resinero. Para entender el proceso social y ecológico y construir el modelo basado en agentes TRUE GRASP, se usaron diferentes herramientas metodológicas y técnicas, como información cartográfica, observaciones empíricas ecológicas y sociales, y experimentos de campo. TRUE GRASP es un modelo educativo virtual diseñado para simular las trayectorias futuras del bosque y contribuir así al aprendizaje colectivo de campesinos y otros actores regionales.

Resumen en inglés

Coffee agroforestry systems are a promising approach to the challenge of sustaining both biodiversity and livelihoods in tropical landscapes. However, coffee farmers' response to the unrelenting coffee leaf rust (CLR) outbreak may have repercussions for the potential of coffee agroforestry systems to contribute to biodiversity conservation. Adaptations in management practices could affect the extent to which farmers rely on ecological processes vs. external inputs (e.g., agrochemicals) to support production. This study investigates farmers' response to CLR outbreak through a study in a forest frontier in a Biosphere Reserve in Chiapas, Mexico. We conducted household surveys and fieldwork before the CLR outbreak in 2011-2012 (n = 59), and follow-up surveys after the outbreak in 2016 (n = 48). Before CLR outbreak, farmers were cultivating Arabica coffee varieties in agroforestry systems and generally following agroecological approaches. Most farmers (82%) were certified organic and did not employ synthetic agrochemicals. Farmers (66%) had plans to expand their Arabica coffee agroforests either into forest (35%) or fallow (31%) in response to high farm gate prices. After CLR outbreak, 94% of farmers had CLR-resistant hybrid coffee varieties (HCV) in their possession and were either incorporating them by substituting affected Arabica coffee plants in existing fields, or by establishing new coffee fields with HCV at lower elevations. In attempts to control CLR, farmers (54%) also applied agrochemicals at least once and, to a lesser extent (19%), removed shade trees. Among the farmers (63%) who were planning on expanding coffee production with HCV, more farmers were planning on expanding on fallow (46%) than forest (17%) compared to the period before CLR outbreak (p-value < 0.05). Public and private actors promoted and distributed saplings of HCV and agrochemicals along with technical assistance.

The promotion of HCV along with fertilizers may result in a substitution of ecosystem functions with agrochemicals, and the need to acquire seeds and saplings outside of farmers’ own resource base and networks. This shift in management strategies generates new instabilities and risks by introducing a new market for HCV about which little is known and by making external agents the holders of productive resources and knowledge.

Resumen en inglés

Win-win solutions might be short-lived. Government permission for smallholder farmers to extract and sell resin from a pine savanna biosphere-reserve in Mexico has settled a long dispute among different stakeholders in the short-term; however, forest production and conservation beyond 20 years are compromised due to low pine recruitment caused by competition with exotic grasses. Grass control practiced by farmers through grazing and fire has previously been discouraged by conservation authorities, which inadvertently limits long-term pine conservation and use. We describe the participatory design, rationale and simulation attributes of an educational, interactive, agent-based model that explores suites of management options and their economic and ecological outputs. We present and analyze the outcomes of four simulation workshops, where farmers and external-actors better grasped the complex ecological interactions involved in conserving and using pines in grazed pine savanna with exotic grasses, and discussed these findings with a long-term vision and tradeoff analysis approach.

Resumen en inglés

Small-scale coffee farmers understand certain complex ecological processes, and successfully navigate some of the challenges emerging from the ecological complexity on their farms. It is generally thought that scientific knowledge is able to complement farmers’ knowledge. However, for this collaboration to be fruitful, the gap between the knowledge frameworks of both farmers and scientists will need to be closed. We report on the learning results of 14 workshops held in Chiapas, Mexico during 2015 in which 117 small-scale coffee farmers of all genders (30% women) and ages who had little schooling were exposed by researchers to a natural history narrative, a multispecies network representation, a board game, and a series of graphical quizzes, all related to a nine-species complex ecological network with potential for autonomous control of the ongoing and devastating coffee rust epidemic that was affecting them. Farmers’ retention and understanding of direct and indirect bilateral interactions among organisms was assessed with different methods to elucidate the effect of adding Azteca Chess gaming sessions to a detailed and very graphical lecture. Evaluation methods that were better adapted to farmers’ conditions improved learning scores and showed statistically significant age effect (players older than 40 had lower retention scores) and gaming effect (lower retention of interactions included in the lecture but not in the game). The combination of lecture and game sessions helped participants better understand cascades of trait-mediated interactions.

Participants’ debriefings confirmed qualitatively that they learned that beneficial organisms and interactions occur on their farms, and that gaming was enjoyable, motivating, and critical to grasp complex interactions. Many of the farmers concluded that the outcome of these interactions is not unique and not always in favor of rust control but is context dependent. Many concluded that there are feasible things they can do on their farms, derived from what they learned, to favor potential autonomous pest control.

Resumen en español

Existe evidencia de la problemática que se vive en Áreas Naturales Protegidas (ANP) por conflictos generados entre las autoridades ambientales y los asentamientos poblacionales. Sin embargo, poco se sabe sobre los conflictos intraterritoriales generados a partir del decreto de conservación. En México, la historia agraria ha sido una determinante en las dinámicas territoriales de las poblaciones asentadas en ANP, debido a los problemas pendientes del reparto agrario. Particularmente en Chiapas, la problemática agraria ha ejercido fuerte presión sobre estos asentamientos. En este contexto se enmarcan dos escenarios, por un lado las poblaciones que son reubicadas o desplazadas de su territorio y de quienes se han realizado diversas investigaciones, sobre todo en la región Selva. En el otro escenario se encuentran, las que permanecen en el territorio pero que son excluidas y marginadas. En la presente investigación se aborda el caso de la localidad de Los Laureles, ubicada en la Reserva de la Biosfera La Sepultura (REBISE). Esta localidad fue catalogada por las autoridades ambientales como asentamiento irregular a causa de su rezago agrario. Como resultado, Los Laureles fue marginada y excluida de los programas y apoyos con los que venían contando desde su asentamiento. Por ello, esta investigación tiene como objetivo identificar y analizar las estrategias campesinas en las dimensiones agraria, económico-productiva y social que han implementado durante el período (1987-2016) los pobladores de la localidad Los Laureles. Para construir su territorio frente al decreto de la REBISE ya que con la entrada en vigor de ésta área protegida fue categorizada por las autoridades ambientales como población “irregular” y por las autoridades agrarias como “nacionaleros” o campesinos sin reconocimiento agrario.

Resumen en inglés

Human induced savannas in subtropical regions are often favored by small-holder farmers for livestock production and extraction of wood or non-wood products. Frequent burning and grazing are required to maintain the savanna vegetation structure. However, in conservation areas, fire suppression is promoted to avoid wildfires; whereas domestic livestock grazing is considered a strong interfering factor for tree establishment, due to trampling and browsing. In tropical forests which were converted to savannas, competitive exotic grasses have often replaced the native grasses. Where exotic grasses are present, aboveground biomass accumulation and thus man-induced fire risk are high and potentially undermine tree recruitment. On the long-term, the savanna state may shift into a grass-dominated state with little tree cover, generating unfavorable conditions from a livelihood perspective. We examined this problem in a human-induced pine savanna in the La Sepultura Biosphere Reserve in Chiapas, Mexico. Smallholder farmers highly valued this savanna for both livestock production and resin extraction from the fire resistant pine Pinus oocarpa. However, fire suppression and the presence of exotic grasses are reducing the tree recruitment. The main research question was to what degree can cattle grazing replace fire in its role of biomass removal and thereby stimulate pine recruitment and maintain the desired savanna state. We determined current savanna extension in the region and interviewed farmers to reconstruct past savannazation processes and expansion of exotic grasses. We related adult species-specific tree density to the herbaceous-grass cover, and pine and oak seedling and sapling densities to understory vegetation cover, canopy closure, and cattle grazing history. Finally, a field experiment was conducted to examine the effects of livestock grazing on survival and growth of planted pine saplings.

The savanna currently covers 20% of the study site; it is the result of past slash-and-burn agriculture and selective logging, which have favored the expansion of several exotic grass species. In savannas where exotic grasses are abundant, sapling density was lower compared to sites with a native grass cover. While livestock grazing seemed to increase pine seedling density likely as a consequence of reduced grass cover, pine sapling survival however, was significantly reduced by livestock trampling. By seeking a balance between the livestock’s benefits and adverse effects on pine recruitment, farmers may develop an integrated management system adapted to their specific biotic rangeland conditions. It should allow forage production, while controlling the negative effects of exotic grasses on pine recruitment, thus maintaining a productive pine savanna system.

Resumen en español

La presente obra colectiva analiza desde diferentes enfoques teóricos y metodológicos el proceso de extractivismo de recursos naturales, servicios ambientales y las políticas públicas en este tema en el Sur de México (Chiapas, Oaxaca y Tabasco), y en menor medida en países Sudamericanos. Cada uno de los trabajos que se presentan analiza no sólo el método mediante el cual se ejecuta el extractivismo, sino también los impactos sociales, culturales, ambientales, económicos y de alguna manera políticos en los territorios intervenidos. La falacia de bienestar, progreso y desarrollo se pone en cuestionamiento. Esperamos que la obra sea útil en estos tiempos de incertidumbre e imposición global.

Resumen en inglés

Many studies have considered community-based forestry enterprises to be the best option for development of rural Mexican communities with forests. While some of Mexico’s rural communities with forests receive significant economic and social benefits from having a community forestry enterprise, the majority have not formed such enterprises. The purpose of this article is to identify and describe factors limiting the formation of community forestry enterprise in rural communities with temperate forests in the Southern Mixteca region of Oaxaca, Mexico. The study involved fieldwork, surveys applied to Community Board members, and maps developed from satellite images in order to calculate the forested surface area. It was found that the majority of Southern Mixteca communities lack the natural and social conditions necessary for developing community forestry enterprise; in this region, commercial forestry is limited due to insufficient precipitation, scarcity of land or timber species, community members’ wariness of commercial timber extraction projects, ineffective local governance, lack of capital, and certain cultural beliefs. Only three of the 25 communities surveyed have a community forestry enterprise; however, several communities have developed other ways of profiting from their forests, including pine resin extraction, payment for environmental services (PES), sale of spring water, and ecotourism. We conclude that community forestry enterprise are not the only option for rural communities to generate income from their forests; in recent years a variety of forest-related economic opportunities have arisen which are less demanding of communities’ physical and social resources.
