O sistema de irrigação, as práticas de manejo da água e manejos diferenciados de preparo do solo para o cultivo do arroz são fatores determinantes à produção deste cereal, influenciando de forma diferenciada o efluxo de gases de efeito estufa (GEE), sendo que alguns desses apresentam potencial mitigador das emissões de GEE.

Los Sensores Remotos se han convertido en los últimos tiempos en una herramienta importante para la planificación territorial, debido a la originalidad metodológica con la cual operan y el amplio espectro de observación de la superficie terrestre. El número de algoritmos disponibles en la literatura científica, permiten tratar individualmente muchas de las coberturas terrestres y caracterizarlas en base a su comportamiento espectral. En el presente trabajo se han aplicado dos métodos de clasificación de imágenes: árboles de decisión o reglas y clasificación no supervisada.

Un mapa de deforestación del território mexicano, derivado de Ia sobreposición de dos cartografias de uso del suelo y vegetación de 1993 y 2000, se comparo con variables espaciales como el aislamiento (distancias a Ias carreteras y a Ias poblaciones), Ia topografia (altitud y pendiente), el tipo de suelos y el estatus de protección (dentro de una ANP o fuera) en un sistema de información geográfica (SIG).

Building soil conservation practices on a base of indigenous knowledge greatly increases the rate at which they are adopted by farmers in Burkina Faso. Indigenous soil conservation practices are ecologically sound and need to be taken into account when efforts are made to introduce modern agricultural techniques. This article provides an example of how soil conservation practices built upon local systems for conserving resources were preferred by small-scale farmers over newly introduced conservation techniques.

Focuses on two themes in the study of ethnopedology: (1) the hows and whys of indigenous soil classifications. (2) the differences and overlaps between indigenous soil classifications and western soil classifications. Aims to come to a synthesis of how to link the two sources of information to improve the success of cooperation in sustainable agricultural development.

Over the last 25 years civil disturbances, drought, population increases and global market pressures have all contributed in direct and indirect ways to a modification of Sub saharan African land cover. 

In Nepal, natural factors such as heavy seasonal precipitation, the erosion-prone nature of the soil, steep topography and the removal of ground cover, make the country's hill soils particularly vulnerable to leaching of organic matter and micronutrients.

The Kailash Sacred Landscape (KSL) spreads across a vast region that includes remote portions of the Tibet Autonomous Region of China (TAR China) and contiguous areas of Nepal and India. This area is historically, ecologically, and culturally interconnected; it is the source of four of Asia’s most important rivers, and at the heart of this landscape is the sacred Mount Kailash, revered by millions of people in Asia and throughout the world.

This study sought to determine a 22-year past and future land use and land cover trend and its implication on green spaces in an eThekwini Municipal Area’s peripheral settlement. Results show a consistent pattern of decline in land use and land cover types associated with green spaces and an increase in impervious surfaces. The study is taken to confirm recent urban bio-physical transformation and anticipated increased pressure on peripheral urban green spaces in eThekwini Municipality.

You can carry out your own analyses on poverty and ecosystem services with the GIS data made available, some of them being publicly released for the first time. All data are accompanied by metadata.

• Population & poverty
• Agriculture
• Land cover & land form
• Base data

In this study, methods, originally developed to assess life course trajectories, are explored in order to evaluate land change through the analysis of sequences of land use/cover. Annual land cover maps which describe land use/land cover change for the 1985–2017 period for a large region in Northeast Brazil were analyzed. The most frequent sequences, the entropy and the turbulence of the land trajectories, and the average time of permanence were computed. Clusters of similar sequences were determined using different dissimilarity measures.
