Browsing of forest frontiers by cattle in sub-tropical landscapes is detrimental to ecosystem health, but essential to smallholder livelihoods. We described a silvopastoral landscape, searching for browsed plants to assess how much of the forest is actually used for this end, and also searching for potential new useful species for silvopastoral purposes. The first objective was accomplished through a floristic description, making observations of individuals with browsing marks. Information from interviews, bromatological analyses and vegetative propagation tests further complemented this information to achieve the second objective. We classified the results using Fuzzy Inference Systems (FISs). A great variety of nutritious browsed plants was found, distributed across various types of vegetation, growth habits and taxonomic groups: forest frontiers already are like silvopastoral systems. Various plants like Acalypha leptopoda, Montanoa tomentosa and Verbesina perymenioides are interesting prospects for further intensification of silvopastoral systems.

Resumen en inglés

The Scientific Forestry and the associated management practices received significant attraction around the world which resulted in the birth of professional forestry education. In India, the professional forestry education was started in the year 1985 and currently offered at several State Agricultural and Central Universities. The Forestry and Agroforestry has also been incluzed as a subject in various under graduate and Post graduate program of State Agricultural and other conventional universities. This professional education in forestry and introduction of forestry courses to other degree programmes demand a comprehensive text book encompassing all the facets of forests. Against this backdrop, the current book on Introduction To Forestry & Agroforestry is conceived to cater to the needs of professionals in B. Sc (Forestry), B.Sc (Agriculture), B.Sc. (Horticulture) and B.Sc (Sericulture) courses offered at State Agricultural Universities and undergraduate programme of Botany and Environmental Science courses offered at Conventional Universities. Besides, the book can also act as a fast and ready made reference material for the graduates aspiring for State and Central Forest Service Examinations. For any beginner in professional forestry education and competitive examinations, this book will be an asset to understand and learn the principles and practices of forestry coupled with other recent developments in forestry sector.

Resumen en inglés

With the aim of knowing the level of technology adoption that has a group of cattle producers (peasants) participants of the Sustainable Rural Development program in Biological Corridors (SRDBC) in the Lacandon rainforest, Chiapas, we calculated the rate of adoption technology (RAT) and correlation tests were conducted to identify the socioeconomic variables that influence with the RAT. The values obtained indicate that the level of technology adoption of the study group was intermediate (RAT = 54.83 ± 9.23); the technological components focused on animal nutrition, management of the pastureland, restoration and revegetation in pastures and livestock infrastructure obtained the highest values. The adoption of sustainable livestock technologies was related (P>0.05) with years of participation in the program SRDBC, the amount of bovine heads and the income from the sale of animals. The lack of credit and financing, of market structures and of knowledge regarding the management of livestock techniques were the main limiting for technology adoption. The results of this study contribute to the planning and refocusing of technology transfer programs with the aim of achieving sustainability in the production of cattle in the Lacandona rainforest (Chiapas, Mexico).

Resumen en inglés

Understanding carbon (C) dynamics of the silvopastoral systems can help mitigate greenhouse gas emissions. The aim of this study was to evaluate the C concentration and storage in above- and belowground tree biomass as well as in the soils of fodder banks of Leucaena leucocephala (Lam.) de Wit, Guazuma ulmifolia (Lam.) or a combination of the both species. The above- and belowground biomass was quantified by the destructive sampling. We also obtained samples from soil pits, 20-cm deep, and determined bulk density and organic carbon concentration. The mixed species banks produced more foliage dry matter (DM) (6.3 t DM/ha) than the pure fodder banks. The total living biomass stocks ranged from 31.5 to 33.5 t DM/ha and did not differ between fodder bank types. The tissue C concentration was greater in stems (45.1%) and roots (44.9%) compared to the foliage component (43.4%). Total soil carbon (TSC) in the 5–10 cm layer was greater in the fodder banks with legumes alone than in mixed species banks (35.7 vs. 30.8 t C/ha). TSC storage in the 15–20 cm layer was greater in the nonlegume fodder bank than in the legume fodder bank (39.8 vs. 34.5 t C/ha). However, to the 0–20 cm layer, TSC was similar for all fodder banks. Thus, the three types of fodder banks had similar total C storage in plant biomass and soil, but the production of foliage biomass was higher in the mixed species banks.

Resumen en inglés

Ant community assembly is driven by many factors including species interactions (e.g., competition, predation, parasitism), habitat filtering (e.g., vegetation differences, microclimate, food and nesting resources), and dispersal. Canopy ant communities, including dominant and twig-nesting ants, are structured by all these different factors, but we know less about the impacts of species interactions and habitat filters acting at the colonization or recruitment stage. We examined occupation of artificial twig nests placed in shade trees in coffee agroecosystems. We asked whether species interactions—aggression from the dominant canopy ant, Azteca sericeasur Longino (Hymenoptera: Formicidae)—or habitat filtering—species of tree where nests were placed or surrounding vegetation—influence colonization, species richness, and community composition of twig-nesting ants. We found 20 species of ants occupying artificial nests. Nest occupation was lower on trees with A. sericeasur , but did not differ depending on tree species or surrounding vegetation. Yet, there were species-specific differences in occupation depending on A. sericeasur presence and tree species. Ant species richness did not vary with A. sericeasur presence or tree species. Community composition varied with A. sericeasur presence and surrounding vegetation. Our results suggest that species interactions with dominant ants are important determinants of colonization and community composition of twig-nesting ants. Habitat filtering at the level of tree species did not have strong effects on twig-nesting ants, but changes in coffee management may contribute to differences in community composition with important implications for ant conservation in agricultural landscapes, as well as biological control of coffee pests.

Resumen en inglés

The ongoing introduction of the exotic Grevillea robusta tree species into agroforestry systems (AFS) of the Indian Western Ghats could become a threat to both climate change mitigation and tree diversity conservation. Here, we quantified carbon (C) storage and shade tree diversity in native forests and coffee AFS under contrasted management (native versus exotic shade trees, Robusta versus Arabica systems) at 67 plots along a 3500mm precipitation gradient in the Cauvery watershed, India. Despite a substantial reduction of shade tree cover in native AFS compared to forest (from 90% to 32% in the high precipitation area), native AFS and forests displayed high and comparable C stocks (max. 228 MgC ha−¹ and 234 MgC ha-¹, respectively) and tree diversity (max. 44 and 45 species, respectively). Both variables were negatively impacted by the introduction of G. robusta, especially in Robusta coffee systems (max. 158 MgC ha−¹, 12 species). The current trend toward the introduction of G. robusta in coffee AFS of the study area (exotic agroforestry) negatively affects C storage and tree diversity, especially in Robusta coffee systems. Policy makers should take advantage of the carbon-tree diversity positive correlation found in the agroforestry landscape of the Western Ghats of India to promote conservation and climate change mitigation.

Resumen en español

Quienes realizamos investigación ecológica forestal y agroforestal reconocemos crecientemente la indisoluble interacción entre los procesos ecológicos y sociales, y nos vamos sumando a los esfuerzos de investigación multi- y transdisciplinaria y de acción entre múltiples actores sociales. Esto ha modificado en diversos sentidos y grados nuestros objetivos, conceptos, escalas, métodos y prácticas. La investigación participativa ecológica forestal y agroforestal (IPEFA) se concibe y se practica de muy distintas maneras, definidas por voluntad de quienes investigan y/o por las circunstancias que enfrentan. Aquí presentamos y reflexionamos nuestra experiencia directa en 2 procesos de IPEFA que hemos coordinado en la última década en territorios campesinos pobres y medios de la Sierra Madre de Chiapas: la cuenca alta del río El Tablón en la Reserva de la Biosfera de La Sepultura (LGB) y las cuencas de los ríos Xelajú y Bacantón (alto Grijalva), en los municipios de Motozintla y Mazapa (MGE).Presentamos logros, pero sobre todo destacamos algunos de los mayores retos que enfrentamos y aquellos caminos que no siempre llegaron a buen puerto. Creemos que varios de estos retos académicos, sociales, e institucionales son compartidos por la comunidad mexicana e internacional que practica la IPEFA y que se esfuerza continuamente por superarlos.

Resumen en inglés

Those of us who conduct forest and agroforest ecological research increasingly recognize the interaction between ecological and social processes and join multi and transdisciplinary research and action efforts involving multiple stakeholders. This has changed in various degrees our goals, concepts, scales, methods and practices. Ecological participatory forestry and agroforestry research (IPEFA) is conceived and practiced in many different ways, defined by the will of those who investigate and (or) the circumstances they face. Here we present and make a reflection of our direct experience in two IPEFA processes we have coordinated in the last decade in poor rural territories of the Sierra Madre de Chiapas: the upperbas in of El Tablón River in the Biosphere Reserve La Sepultura (LGB), and the basins of the rivers Xelajú and Bacantón (High Grijalva), in the municipalities of Motozintla and Mazapa (MGE). We present achievements, but above all highlight some of the biggest challenges we have faced, and those roads that did not always lead to good results. We believe that several of these academic, social, and institutional challenges are shared by Mexican and international researchers that practices IPEFA and continually strive to overcome them.

Resumen en español

Este estudio es una aproximación etnográfica a la experiencia de campesinos indígenas de Chiapas, México, participantes en un proyecto de pagos por servicios ambientales con fines de restauración ecológica y reforestación, el proyecto Scolel-Té, pionero en el establecimiento de parcelas agroforestales para la captura de carbono. El objetivo es comprender qué papel juega el incentivo económico en la permanencia o abandono de la siembra de árboles en la milpa desde la racionalidad del productor. Mediante la aplicación de entrevistas a profundidad con campesinos indígenas en cuatro zonas del proyecto y en diferentes fases de establecimiento de los sistemas agroforestales, se investiga cómo valoran los participantes en el proyecto los conocimientos adquiridos; las actitudes hacia los cambios ambientales en sus territorios; las modificaciones introducidas en sus estrategias productivas a raíz de la siembra de árboles; las motivaciones que llevan a participar en el proyecto y a continuar una vez finalice el pago; y cómo valoran los productores su experiencia. Se concluye que la adopción inicial de la práctica de sembrar árboles en parcelas de cultivo es alta y está fuertemente impulsada por el pago por captura de carbono. Sin embargo, la integración de las prácticas agroforestales desligadas de un incentivo económico es débil.

Resumen en inglés

This study employs an ethnographic approach to the experience of indigenous peasants in Chiapas, Mexico, participating in a project of payments for environmental services for the purpose of ecological restoration and reforestation, The Scolel-Té project, which pioneered the establishment of agroforestry plots to capture carbon. The objective is to understand what role the economic incentive plays in the permanence or the abandonment of the practice of planting trees in the milpa system from the rationality of the peasants. By applying in-depth interviews with indigenous farmers in four project areas and at different stages of establishment of agroforestry systems, we explore the acquired knowledge of the peasants; attitudes towards environmental change in their territories; amendments to its productive system as a result of tree planting strategies; the motivations for participating in the project and the integration of agroforestry practices after completion of the payment; and how producers value their experience. We conclude that the initial adoption of the practice of planting trees in farmer agricultural plots is high and is strongly driven by the payment for carbon sequestration. However, the integration of agroforestry practices detached from an economic incentive is weak.
