A comprehensive strategy called Integrated Catchment Management (ICM) aims to integrate into management plans the social, economic, and environmental factors associated with a water basin. The significance of ICM as a strategy for coping with issues like drought and flooding arises from the growing effects of climate change and the rising demand for water supplies. Coordination between different stakeholders, such as farmers and local communities, is necessary for this strategy to guarantee the sustainability of natural resources and provide long-term advantages for present and future generations.

What is Integrated Catchment Management (ICM)?

In its broadest definition, ICM recognizes the necessity of incorporating all environmental, economic, and social concerns that are present in or associated with a river basin into a management philosophy, procedure, strategy, or plan. Therefore, ICM seeks to preserve the natural resources that these communities depend on while generating the widest range of long-term advantages for present and future generations.

Water resource managers frequently believe that “ICM” can be accomplished simply by working together to regulate water consumption and safeguard the integrity of water resources in a catchment area. Whilst this approach has had some success, it ignores the complex issues of land use patterns and the varied roles played by stakeholders, communities and governments.

Why is this approach needed?

As our climate changes, we recognize the urgent need to expedite current and future plans in order to adapt and develop solutions for threats such as drought and flooding. Furthermore, as consumer expectations shift, there is a greater emphasis than ever on maintaining vibrant habitats and healthy watercourses. The magnitude of the issue at hand is so tremendous that governments and organizations throughout Europe and the rest of the world are realizing the need to modify their current methods for managing and planning water and landscapes. To stop environmental deterioration, we must all work toward more sustainable catchment management.

How does Integrated Catchment Management work?

The process and mentality of integrated catchment management involves working together to make catchment choices by applying a systems-thinking methodology. The advantages and effects of every pertinent stakeholder’s viewpoint are taken into account and appreciated. In order to optimize shared advantages, such as biodiversity net gains and ecosystem services, social value and natural capital strategies are employed. Together with this, funding strategies are being developed to deliver actions that are prioritized in a political, social, economic, and environmental context.

Key principles and driving forces of ICM

Integrated Catchment Management (ICM) is based on five key principles or characteristics, which involve:

A systems approach which recognizes the individual components as well as the linkages between them, and addresses the needs of both the human and natural systems
An integrated approach, rather than a comprehensive approach, in which attention is directed towards key issues of concern identified by all stakeholders in the process.
A stakeholder approach which recognizes the importance of involving individual citizens and landowners, as well as government agencies, in a participatory process to define all decisions around conservation and use of natural resources.

A partnership approach which promotes the search for common objectives, and defines the roles responsibilities and accountabilities of each agency and individual who participates in the process of decision-making.
A balanced approach where close attention is given to decisions designed to achieve a sustainable blend of economic development and protection of resource integrity, whilst meeting social norms and expectations.

The ICM approach essentially aims to strike a balance between the conflicting demands of long-term resource integrity preservation, the strong desire for social advancement and uplift, and the requirement for ongoing economic growth and environmental resource use.

How ICM be truly effective

It can be necessary to coordinate land and water management in a way that goes beyond the typical “physical” borders of a single watershed.
Effective resource management may and should be ensured by the active participation of all landowners and other stakeholders.
Stakeholder relationships should be built on trust, with a sustained dedication to and continuity of the catchment management process.
The way that catchment limits are defined may need to change based on how stakeholders define common concerns.
Certain institutional arrangements might need to be adaptive and flexible within various catchments in order to fit the unique needs of each scenario.
Realistic short- and medium-term goals are also required, even though ICM is a long-term process.

Catchment pioneers

Various community and regional schemes are emerging across the UK to enhance integrated and accountable water management, often driven by the desire to increase private sector investment. A notable example is the Wyre Community Interest Company (CIC), established in 2021 by the Rivers Trust, which aims to reduce flood risk through natural flood management in the Wyre catchment, Lancashire. The CIC has successfully built a governance structure to manage £2 million in funding from stakeholders like United Utilities and the Environment Agency, without relying on government agricultural subsidies.

Defra’s pilot ELMS ‘Landscape Recovery’ scheme, launched since the Wyre CIC, allows farmers to collaborate on plans to improve natural habitats while attracting private funding. In the Darent valley, a similar pilot is underway, supported by local trusts to restore river habitats and enhance groundwater supplies.

The Landscape Enterprise Network (LENS) model takes a business-centric approach, facilitating co-investment in landscape measures. In the Petteril catchment, United Utilities and Nestle are co-funding soil management improvements through a dairy cooperative, aiming to reduce phosphate pollution and strengthen Nestle’s supply chain resilience.

Emerging insights

Many initiatives currently focus on narrow aspects of water management, such as flood risk or water resources, indicating that truly holistic management is still a distant goal. A phased integration approach is suggested, starting with combining funding overseen by the Environment Agency to achieve multiple outcomes, including Natural Flood Management and expanding to encompass wider flood risk management and private sector funding.

Despite the UK government’s ambition to boost private sector investment in climate adaptation, securing non-grant funding remains challenging. Businesses require a solid business case with measurable outcomes to invest, as vague initiatives often fall into token CSR funding. Government policies must establish clear engagement rules for ‘nature markets’ and provide seed funding to initiate complex schemes.

While significant private funding is directed towards river improvements through the Water Industry Natural Environment Programme (WINEP), it has been tied to specific regulatory outcomes, complicating integration with other funding sources. Additionally, with 70% of the UK covered by farmland, effective catchment management will require farmers to collaborate, ensuring that initiatives are economically viable and compatible with productive farming. Certainty and transparency regarding agri-environment subsidies and tax rules are essential for success.

Conclusion

One essential tool for tackling difficult environmental and socioeconomic issues is integrated catchment management. A balance between preserving natural resources and advancing economic development can be struck by encouraging cooperation among all parties involved and putting sustainable plans into practice. Everyone’s dedication to cooperating to guarantee efficient and sustainable management of water resources is essential to ICM’s success.
