Reduce flood risk

NAIAD Case study: Thames basin demonstration site

 The floodplains of the River Thames are characterised by high land prices and intense urbanisation, with few options for creating extra flood storage.  A number of tributaries of the fluvial Thames suffer localised flooding in urban reaches, affecting local inhabitants, businesses, property and infrastructure. 

Recently there has been UK government investment in natural flood management (NFM) and there is growing interest in how land management such as Conservation Agriculture can provide water management for storing flood water as well as biological benefits....

NAIAD Case studies: Lez river basin (France)

The Lez river (29 km long) is a small coastal Mediterranean river with a watershed of 746km2. Its spring is the outlet of a large karst aquifer. It then crosses natural and agricultural areas before reaching the plain of Montpellier (with 290 000 inhabitants) and the Mediterranean Sea. The Montpellier plain is characterized by a rapid urbanization with massive land artificialisation and soil-sealing (2920ha decrease of agricultural and natural areas from 1990 to 2012).

The watershed is exposed to a typical Mediterranean weather marked by repeated...

BEGIN (Blue Green Infrastructure through Social Innovation)

Together we can build more resilient and liveable cities

The overall objective of BEGIN is to demonstrate at target sites how cities can improve climate resilience with Blue-Green Infrastructure involving stakeholders in a value-based decision- making process to overcome its current implementation barriers.

BEGIN’s driving ambition is to substitute traditional ‘grey infrastructure’ such as concrete for ‘blue-green infrastructure’ (BGI) such as parks, rivers, and lakes.

Habitat enhancement of stone clad sea walls.

Seawalls are usually seen only as flood alleviation structures rather than as having other possible functions to benefit the wide environment. Where new walls are being installed there is opportunity to include more sympathetic “nature friendly” textured finishes to improve or maintain biodiversity. Where seawalls are already installed, retrofit enhancement measures provide significant opportunities. Small alterations were made to the mortar pointing between decorative stone cladding of a section of vertical concrete wall during construction of the Shaldon and Ringmore Tidal Defence Scheme...

NAIAD Case Studies: Brague Demonstration site (France)

Nature Based Solutions management is more than a technical problem: specific design and integrated decision-making frameworks are needed. From a more global point of view, choice of Nature Based Solutions and effectiveness assessment require specific principles mixing pluridisciplinary quantitative and qualitative criteria and indicators. It is important to note that the choice and definition of NbS’ effectiveness indicators highly depend on time, spatial scales and decision-making contexts. La Brague DEMO proposes some pathways to contribute to this objective. It is indeed essential to...

NAIAD Case Studies: Lower Danube Demonstration site (Romania)

The Lower Danube demo case has as main objective to create an efficient network of national, regional and local stakeholders in order to apply collaborative approach for water security measures and extreme meteorological events mitigation by using the ecosystem service and green infrastructure. In the NAIAD project the Lower Danube demo case study is focused on understanding the social risk perception and challenges for NbS implementation, to open business opportunities for insurance sector and to identify potential business model to foster Nature Based Solutions implementation and...

NAIAD Case Studies: Glinščica Demonstration Site (Ljubljana, Slovenia)

Glinščica catchment

The aim of Slovenian demo is to prepare a comparison of Nature based solutions and grey scenarios for the Glinščica catchment area, valuate the ecosystem services provided by implementation of restoration and management measures developed within the project and to develop and deploy economic and/or financial instruments (in the form of nature assurance schemes) for effective business models in the field of ecosystem services, green infrastructure and river restoration that would highlight the importance of understanding the value of ecosystems in the long run.
