The Galapagos Islands are a unique sanctuary for wildlife and have gone through a fluctuating process of urbanization in the three main inhabited islands. Despite being colonized since the 1800s, it is during the last 25 years that a dramatic increase in population has been observed. Analyzing impervious surface change over this period in an ecologically fragile environment is a challenging task, thus two methods that have been widely employed in studying urban environments were compared in this study: sub-pixel using spectral mixture analyses (SMA) and object-based classification.

The Salween River originates in the eastern highlands of the Tibetan Plateau and flows through valleys that are at first steep and narrow, then increasingly broad as the river approaches the tropical lowlands. Eventually it enters the Andaman Sea in eastern Myanmar.

The 2815 km long Salween river runs parallel to the mighty Mekong River for much of its course and forms part of the border between Myanmar and Thailand. When it flows through Yunnan, it is known as the Nujiang river.

This region contains Indochina�s largest block of moist forest, one of its richest plant diversities, and its largest number of mammals. This Global 200 ecoregion is made up of these terrestrial ecoregions: Tenasserim-South Thailand semi-evergreen rain forests; Kayah-Karen montane rain forests.

Biome: Tropical and Subtropical Moist Broadleaf Forests...
Size: 5,900 square miles...

Stand on the Shan Plateau, and you'll see mountains everywhere, stretching far and wide. Under your feet lies rocky soil rich with silver, rubies, and sapphires. But the real gem here is Lake Inle. One of Myanmar's few freshwater lakes, Inle contains many unique species of fish.

Lake Inle lies 2,952 feet (900 m) above sea level on the Shan Plateau, an extensive region of high mountain ranges crisscrossed by streams and the mighty Salween River. Inle is a shallow mountain lake that contains several islands and is fed by mountain streams...

El análisis de las transformaciones en el paisaje generadas por la expansión urbana de Cuenca, se realiza a través de una revisión de la historia de la ciudad, para poder obtener una visión sobre su futuro; es decir, qué hicieron nuestros antepasados en esta región, qué estamos haciendo nosotros en el presente y, especialmente, qué debemos hacer para el futuro. En este contexto, se analiza el crecimiento urbano y el incremento poblacional de la ciudad de Cuenca en los últimos cincuenta años.

Una de las principales preocupaciones dentro de los estudios en Tecnologías de Información Geográfica es el desarrollo de metodologías reproducibles en diferentes ciudades que contribuyan al análisis del proceso de urbanización. El objetivo de este trabajo es proponer una nueva metodología que permita extraer la superficie edificada del área urbana y discrimine las distintas densidades que en ella existen. La metodología se basa en imágenes satelitales Landsat 5 TM que presenta una vasta cobertura territorial y temporal que asegura la posibilidad de réplica.

En este trabajo se evaluó objetivamente la relación entre la variabilidad del rendimiento de la pastura en el departamento de Salto (Uruguay) y la variabilidad climática. Se analizaron también las posibles implicancias del cambio climático futuro. Se utilizaron datos diarios y mensuales de la estación meteorológica Salto en el período 1961-1990 y un registro de datos experimentales de crecimiento de pastura en el período 1980-1994. Adicionalmente, se emplearon salidas diarias de reanálisis del NCEP y de los Modelos de Circulación General HadCM3 y CSIRO-Mk2 para los escenarios A2 y B2.

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.

Artisanal and small-scale mining affects the quality and components of the environment in the Batouri area in different ways. Activities interfere with air, soil, water, fauna and forest resources. This study seeks to assess the impacts of mining on the environment using a combination of spatial analysis, questionnaires administration and Leopold’s grid of impact assessment. The impacts of mining on physical environment include air pollution by emission of dusts and fumes from engines, soil and subsoil degradation by earthworks and release of wastewater containing chemicals from companies.
