Fires and the Water Cycle: Impacts and Management

Fires can have severe impacts on water quality. Fires disturb vegetation cover, create an ash layer rich in potential contaminants, and increase contaminant mobilisation by enhancing runoff and erosion. This may lead to the contamination of surface and groundwater resources with suspended sediments, metals, organic compounds and nutrients. While many of the potential impacts are known, key knowledge gaps remain on their probability of occurrence, magnitude, and longevity. Overcoming these gaps is essential to support decision-makers in addressing these risks.

Geophysics and technology innovations for sustainable soil and water management

Saltfree is a project under the ARIMNet2 program, which focuses on geophysical methods for prevention of salinization in irrigated agricultural areas around the Mediterranean. In this workshop, we propose to discuss in a broader scope the use of innovative approaches and tools for tackling the important challenges of sustainable management of soil and water use. 

Porque está a NASA a estudar a água mineral de Cabeço de Vide?

Portugal possui o mais rico e diversificado Património Hidrotermal da Península Ibérica. A água é, por si só, um dos recursos primários e fundamentais à existência de vida, pelo que importa compreender onde e como existe, como interage com o solo e com a floresta, e como a tratamos, pois sem este conhecimento não conseguimos assegurar a sua exploração sustentável.

Impacts of Fire on Water Quality

2017 was marked by wildfires which ravaged Portugal and other regions around the world. The ash generated by these fires can contaminate downstream rivers and reservoirs, harming aquatic ecosystems and limiting water resources for human use. There is an urgent need to understand transport pathways, determine post-fire contamination risks, design effective mitigation measures, and support long-term land-use planning in fire-prone forests.
