Lymantria dispar es una plaga cuarentenaria ausente de Sudamérica, para la que se ha elaborado un plan de vigilancia fitosanitaria regional, debido su elevado riesgo de introducción involuntaria a través del comercio. El objetivo de este trabajo fue estimar la distribución geográfica potencial de L. dispar en una nueva área utilizando un enfoque deductivo, a fin de priorizar ambientes en riesgo para su monitoreo preventivo. En Sudamérica se evaluó la susceptibilidad de la cobertura boscosa ante diferentes escenarios climáticos.

Complexities in the rates and patterns of change necessitate the consideration of alternate futures in planning processes. These scenarios, and the inputs and assumptions used to build them, should reflect both ecological and social contexts. Considering the regional landscape as an anthrome, a priori, assumes human needs and institutions have a fundamental role and place in these futures, but that institutions incorporate ecological limits in decision making.

Este trabalho apresenta, além do referencial teórico construído, dados que foram coletados junto a radialistas e um historiador e pesquisador. Vale ressaltar que, na cidade, a população de profissionais que trabalham junto às rádios e instituições culturais é maior do que o número de entrevistados, pois os respondentes participaram voluntariamente desta investigação. Foram aplicados questionários compostos por perguntas fechadas, cujas respostas foram formatadas para que seguissem o esquema proposto por Likert.

Study region : In this study, 33 catchments across the Lower Mekong Basin in Southeast Asia are examined to detect historical changes in their hydrological response via a model-based methodology.Study focus : Intensive development over the past half century across Southeast Asia’s Lower Mekong Basin has inevitably affected natural resources. Large areas have been converted from forests for subsistence and commercial agriculture, and urban development. We implement an innovative approach to screen hydrologic data for detecting impacts of such large-scale changes on hydrological response.

Increasing climate variability and challenge in access to water pose major impediments to rainfed agricultural productivity. Extensive flooding of agricultural lands during the rainy season and lack of water during the 8-month long dry season affect the livelihood of the people in the northern Ghana, a situation that calls for better water management practices. The use of aquifer storage and recharge (ASR) based technique, helps to reduce flooding and improve access to water during the dry season; however such technology has specific requirements for successful implementation.

Although Ethiopia has abundant land for irrigation, only a fraction of its potential land is being utilized. This study evaluates suitability of lands for irrigation using groundwater in Ethiopia using GIS-based Multi-Criteria Evaluation (MCE) techniques in order to enhance the country's agricultural industry. Key factors that significantly affect irrigation suitability evaluated in this study include physical land features (land use, soil, and slope), climate (rainfall and evapotranspiration), and market access (proximity to roads and access to market).
