Ocean scientists and researchers released a new publication warning of the sea level rise and its impacts on freshwater systems, given the current and future climate scenario. Titled “Navigating the Future VI”, the article shows that rising sea levels may be affecting the availability of freshwater. The work was published on October 23rd.
Node textmarine science experts say that the ocean and freshwater can no longer be considered and managed separately.
“Global warming causes sea level rise, which is pushing seawater inland into rivers, swamps and underground freshwater reserves, with negative effects on water quality,” says Peter Kraal of NIOZ Sea Research, co-leader of the freshwater and ocean chapter in the article, in press release.
In the chapter, the author explains that rising sea levels and their impact on fresh water can lead to changes in the living conditions of aquatic fauna and impact the suitability of this water for consumption and agriculture.
The article excerpt also indicates that saltwater “intrusion” — the movement of saline water into freshwater systems — also occurs underground, amplified by the excessive extraction of fresh groundwater by human activities. This practice can alter the chemistry and quality of coastal aquifers, according to the authors.
“Additionally, human activities generate waste streams with cocktails of dangerous chemicals that enter the global water cycle, making their way from freshwater reservoirs to the ocean. Freshwater and the ocean are closely connected and affect each other; we need to understand how to sustainably use both components of the global water cycle,” adds Kraal.
Article reinforces the importance of new policies to manage ocean resources
Navigating the Future VI is a position paper of the European Marine Board (EMB) and explores the role of the ocean in the broader Earth system and promotes collaboration between disciplines to address global issues.
According to statement published by EMBthe document aims to influence and guide international, European and national research funding programs, policy development and inspire the scientific community.
The paper highlights the need for a new approach to managing ocean resources. “The ocean is no longer seen as an isolated ecosystem; it is recognized as a key element in regulating climate, sustaining biodiversity, ensuring access to freshwater and supporting human livelihoods. However, the ocean is also under immense pressure from climate change, pollution and unsustainable exploitation,” says the EMB statement.
The document was structured around four main themes: people, climate, freshwater and biodiversity. Among the recommendations made by the article are marine research priorities to face challenges related to climate change, from strategies such as water resilience and climate adaptation, to protecting biodiversity and understanding the relationship between the ocean and population.
