This case study examines the Upper Klamath Basin of Oregon, which is experiencing a water crisis due to over-allocation. The purpose of this case study is to identify land cover / land use change looking specifically at wetland conversion and to discussion the effects of wetland loss on ecosystem services....
Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...

La lagune de Nador se caractérise par un écosystème semi-fermé, en communication avec la mer par une étroite passe. Cet écosystème est sous l'influence de plusieurs facteurs externes tels que l'ensoleillement, l'apport en eau douce, les eaux de ruissellement, le lessivage des champs agricoles et les eaux usées urbaines. L'influence...
Le projet «système d’information géographique pour les pêcheries en Afrique de l’Ouest » a pour objectif de promouvoir l’utilisation des systèmes d’information géographique comme outil d’aide à la décision en matière d’aménagement des pêcheries. Un rappel préliminaire des critères caractérisant un produit d’aide à la décision (accessibilité technique, disponibilité en...
Global aquaculture production increased with an average rate of 10% per year since 1990 and 90% of
aquaculture production comes from developing countries thus providing livelihood and income especially
to marginal groups who have limited access to resources such as agricultural land and financial capital.
Geographical information systems (GIS) based...
Ever expanding pressures on the health and productivity of our oceans and coasts from threats such as coastal development and climate change are stressing the need to consider the full spectrum of factors, scales, datasets, opinions, and trade-offs for current and future coastal management actions (Guerry 2009; McLeod and Leslie...

Although the ocean provides living space for about 97 percent of life on Earth, less than 5 percent of the ocean below the surface has actually been seen, let alone explored. Now, using the geographic information system (GIS), marine scientists are gaining new insights into a once-mysterious world. A technologically...
The data represent 48-state USA weather and climate data (both site and gridded), biological phenology (developmental) models, combined with photoperiod response (diapause inducing sensitivity to short daylengths). The example data sets are specific to a single insect biological control organism (a leaf beetle introduced to control purple loosestrife, an invasive...
