However, some attendees of the Ocean Days event left sceptical about the degree of meaningful implementation resulting from such gatherings. It is important to translate high level discussions with European ocean leaders into practical tools and mechanisms that can result in noticeable change.

One of the major policy discussions at the event focused on the European Water Resilience Strategy to address escalating water stress. This topic is prescient given that half of Europe’s river basins expected to face shortages by 2030. While the Water Framework Directive (WFD) exists, poor enforcement has hindered progress.

Recent EU efforts include the Water Resilience Initiative, a European Parliament report urging water integration into policies and a Knowledge Innovation Community launching in 2026. Financing remains a challenge, with an estimated €63bn ($68bn) in annual investment, but a proposed dedicated fund could bridge gaps. The EU’s leadership in water resilience could shape global policies for sustainable resource management and climate adaptation.

The thriving Blue Economy of Europe offers social as well as financial benefit. Turning Blue, an EU-funded project, is one example of its potential. The scheme helps young former inmates find employment in Europe’s blue economy, addressing both labour shortages and high reoffending rates. Operating in Portugal, the Netherlands, Romania, Cyprus and Italy, the initiative provides training, mentorship and employer connections in industries such as aquaculture and coastal tourism.

Many young offenders struggle to secure jobs due to stigma and lack of life skills, making reintegration difficult. Through VR experiences, industry talks and hands-on guidance, the programme introduces new career paths, aiming to break the cycle of recidivism.

A recent study in Nature examines sustainable marine development in 15 EU coastal countries from 2012 to 2022, assessing weak and strong sustainability in the blue economy. Using Sustainable Development Goal 14 indicators, it evaluated national progress in balancing economic growth with environmental preservation. Findings show that while seven countries achieved both weak and strong sustainability, seven progressed only under weak sustainability and one made no progress.

The report highlights challenges in policy enforcement, data limitations and financial constraints in achieving ocean health. Estonia, Lithuania and Poland led in sustainable progress, while the Netherlands lagged. The study highlights the need for more comprehensive data, balanced sustainability measures and stronger governance to ensure equitable and lasting marine economic development.

The European Ocean Pact proposes a comprehensive framework integrating environmental sustainability, economic growth and maritime security. It emphasises restoring marine ecosystems, protecting biodiversity through Marine Protected Areas (MPAs), tackling marine pollution and strengthening enforcement of the Water Framework and Marine Strategy Directives.

The pact supports the blue economy by promoting decarbonisation in shipping, expanding offshore wind and blue carbon projects and ensuring a fair transition for fisheries and aquaculture. It also enhances maritime security by protecting submarine cables, monitoring illegal fishing and strengthening EU naval and coast guard capabilities.

Key initiatives include the Green Ports Initiative, harmonised maritime spatial planning and international agreements on sustainable fisheries and plastic waste reduction. A roadmap and mid-term assessment will ensure progress.

Around 50% of countries currently depend on water supply from neighbouring countries. The report also calls for a move towards “water as a human right”, and the creation of a United Nations agency for water scarcity.

Why does this matter? In the World Economic Forum’s annual risk report, water scarcity has consistently secured a spot among the top five risks to the global economy. Multiple factors contribute to this scarcity in the UK, including the impact of climate change, which has led to more frequent and intense heatwaves and droughts. Following the current trajectory, the Environment Agency forecasts that by 2050, average summer temperatures will increase by 7.4C, causing a 50-80% decline in river levels and reducing freshwater availability by 10-15%. Meanwhile, average water consumption in the UK has risen YoY since 2014, reaching 143 litres per person per day. Demand now outstrips supply – In England, water levels in 28% of groundwater aquifers and 18% of rivers and reservoirs are declining, according to government figures. Much of this demand is spurred by domestic and agricultural use.

Domestic water use – Changing social norms is an important facet of tackling the water crisis, with many calling for a reframing of how we view and use water. As eloquently put by the Chief executive of the Environment Agency in 2019 “we need water wastage to be as socially unacceptable as blowing smoke in the face of a baby”. Numerous questions arise regarding domestic water usages, such as the necessity of flushing waste with clean drinking water and the appropriateness of using drinking water for hosepipes.

Reframing grey water – In India, where the water crisis is particularly acute, trials using grey water to flush toilets are underway. Grey water can be taken from baths, showers and sinks (outside of the kitchen), representing 50-70% of domestic water use. A home-installed system can lightly treat the water for reuse. The heat from bath or shower water can also be reused, with up to 60% of the heat recovered. Today, UK households spend £2.3bn ($2.9) each year heating water for showers and flush 740 billion litres of water down the toilet. Social norms are a barrier to the uptake of these technologies. However, as the water crisis intensifies, circular solutions may become mainstream.

Agricultural water use – Agriculture uses a staggering 65-70% of the world’s freshwater, with almost half of this wasted. Reducing water use in agriculture can be approached from several angles. For example, from a wastage perspective, losses occur at every stage of the food system, from planting and harvesting to storage and transportation – one study suggests that 44% of crops grown are lost before they reach the consumer. Preventing food waste reduces water demand and optimises farmers’ time.

Technology in agriculture – Precision agriculture is one solution to on-farm wastage, harnessing advanced technologies and tools to help farmers make better decisions and improve crop yields. Here, the use of water and other resources is optimised to increase production while reducing the time and effort required. Precision agriculture relies on collecting and analysing vast data sets from various sources, including crop health, soil moisture and soil fertility, enabling farmers to make informed choices. The drawback is the costs which, at present, are high – cameras and sensors mounted to tractors, drones and within the soil are expensive and require interpretation from IT-literate farmers or third-party providers. Small farmers from less developed countries cannot afford these services. However, companies are increasingly harnessing open-source data and data analytic tools available on smartphones to increase access to the benefits of precision agriculture for more farmers.

Changing diets – Further down the supply chain, consumers can reduce their freshwater footprint by choosing foods that do not require intense irrigation. Approximately one-third of the water used in agriculture is related to the production of livestock, but the nutritional returns are not relative. For example, a gram of protein provided by beef requires 20 times the amount of water compared to the same protein provided by cereals and starchy roots, according to a study. Changing diets may be an important tool in the water crisis.
