Observe - Understand - Decide

Increasing populations and growing prosperity place pressure on the natural environment and result in problems such as contamination of land and water resources, desertification and overgrazing. In turn, the depletion of natural resources can frequently lead to land scarcity and widespread changes in land use. Environmental issues, such as climate change, transcend national boundaries; they impact the whole planet and affect the well-being of nations.

GAF provides best-in-class geo-information solutions and systems that assist with the preservation of the natural environment and the management of the Earth’s natural resources. Our integrated service approach combines information from a range of disciplines, topics, sources and scales, and addresses issues from local to continental level. Our genuinely multi-thematic service approach allows us to offer proven solutions customised to the needs of our clients. Geospatial information enables cost efficient and area-wide observation and monitoring of the environment and natural resources. It also helps improve the understanding of the dynamics and complexities of the physical interactions between nature and society. Modelling and scenario development makes it possible for us to describe and forecast the future consequences of decisions made today. In short: GAF provides geospatial data, as well as monitoring, information and decision support systems, that enable the successful management of the environment and natural resources.

Improving water management

The security and sustainable development of our water resources is one of the key challenges of the 21st century. Floods, droughts, water quality, water-ecosystem and soil-water-climate interactions, and the sustainability of resources are important issues in the field of water resources management and hydrology. The land surface, geology, soils and geomorphology govern important parts of the water cycle. Furthermore, climate variability and climate change also impact strongly on the state of the environment and renewable sources of energy; this is an area in which we can offer outstanding services for the mapping and monitoring of desertification, natural greening, reforestation and large irrigation projects.

GAF provides earth observation and geo-information solutions for quantifying the components of the water cycle and other valuable information that is essential in water resources assessment and management. We integrate such information into dedicated geographic information systems, which are tailored to the needs of decision makers, water managers, politicians or the general public, thus enabling informed decision making.
