The demand for agricultural products continues to grow rapidly, but further agricultural expansion entails substantial environmental costs, making recultivating currently unused farmland an interesting alternative. The collapse of the Soviet Union in 1991 led to widespread abandonment of agricultural lands, but the extent and spatial patterns of ab...

Many terrestrial biomes are experiencing intensifying human land use. However, reductions in the intensity of ag-ricultural land use are also common and can lead to agricultural land abandonment. Agricultural land abandonment has strong environmental and socio-economic consequences, but fine-scale and spatially explicit data on agricultur-al land a...

A nationwide multidate GIS database was generated in order to carry out the quantification and spatial characterization of land use/cover changes (LUCC) in Mexico. Existing cartography on land use/cover at a 1:250,000 scale was revised to select compatible inputs regarding the scale, the classification scheme and the mapping method. Digital maps fr...

Después de tres años de ocurrido un incendio de gran extensión, el ocelote casi no hace uso de la zona afectada por el fuego, probablemente porque el hábitat no le favorece para atrapar a sus presas. Durante 10 meses, vimos que el ocelote usó muy poco la zona afectada por el fuego; obtuvimos únicamente seis registros, a diferencia de la zona que n...

QGIS is the most popular free geospatial software in the world. QGIS belongs to the Open-Source Geospatial Foundation (OSGeo). Among the main strengths of this Geographic Information Systems are: the incorporation of tools via plugins, and a community of users and developers in constant growth. Despite the importance on the use of QGIS on the scien...

Fires can pose a threat to forest ecosystems when those ecosystems are not fire-adapted or when forest community conditions make them vulnerable to wildfires. Thus, investigating fire-prone environmental conditions is urgently needed to create action plans that preserve these ecosystems. In this sense, climate variables can determine the environmen...

The increase and preservation of the socio-environmental functions of urban green spaces (UGS) through suitable management is part of the actions of the United Nations’ Sustainable Development Goals. UGS offer benefits to the population in function of their quantity, availability and accessibility. Therefore, we developed a methodology to measure a...

This chapter of the 2020 Report of the FABLE Consortium Pathways to Sustainable Land-Use and Food Systems outlines how sustainable food and land-use systems can contribute to raising climate ambition, aligning climate mitigation and biodiversity protection policies, and achieving other sustainable development priorities in Mexico. It presents two p...

Knowledge of the spatial distribution of agricultural abandonment following the collapse of the Soviet Union is highly uncertain. To help improve this situation, we have developed a new map of arable and abandoned land for 2010 at a 10 arc-second resolution. We have fused together existing land cover and land use maps at different temporal and spat...

Our goal was to understand the underlying drivers and spatial determinants of agricultural land abandonment following the collapse of the Soviet Union and the subsequent transition from state-command to market-driven economies from 1990 to 2000. We brought an example of agricultural land-use change in one agro-climatic zone stretching across Lithua...

Este trabajo trata de definir cuál modelo de distribución de especies es el más adecuado para determinar la distribución potencial de la avifauna en la Reserva de la Biosfera Sierra de Manantlán (Jalisco, México).

El presente trabajo busca obtener información cuantitativa y precisa de los parámetros estructurales que tienen una mayor influencia sobre especies de aves de interés para la conservación o aprovechamiento, en ésta u otras regiones del país con condiciones similares, a través de la caracterización de la estructura vertical del bosque mesófilo de mo...

Electronic waste is a widespread environmental problem. From all waste streams, e-waste is registering one of the largest growing rates (between 3% and 5%). In Mexico, the e-waste recovery system comprises a mix of formal and informal sectors not well known to date. The goal of this article was to analyze electronic waste in Mexico through the acti...

In South American highland forests, domestic grazing can cause major changes in forest structure and soil quality thereby altering resources available to avian communities. However, the consequences of changes in variability in plant growth forms after disturbance are little known. Understanding forest succession effects on avifauna is critical tho...

El presente trabajo busca contribuir a las metas de la Alianza México REDD+, en particular al componente de Monitoreo, Reporte y Verificación (MRV) mediante el establecimiento de una guía que permita medir el impacto de las acciones REDD+ en los ecosistemas, la biodiversidad y los servicios ambientales . El producto final es una propuesta metodológ...

Agriculture is expanding and intensifying in many areas of the world, but abandoned agriculture is also becoming more widespread. Unfortunately, data and methods to monitor abandoned agriculture accurately over large areas are lacking. Remote sensing methods may be able to fill this gap though, especially with the frequent observations provided by...

Protected areas are cornerstones of biodiversity conservation, but they are in danger of becoming islands in a sea of human dominated landscapes. Our question was if protected areas may even foster development in their surroundings because they provide amenities that attract development, thus causing the isolation of the ecosystems they were design...

A wall-to-wall multidate GIS database was generated in order to carry out the quantification and spatial characterization of land use/cover changes (LUCC) in Mexico. The first step was the elaboration of a wall-to-wall updated to 2000 database on land use/cover compatible with previous cartographic efforts. Previous land use/cover maps from two dif...
