A dynamic modeling of cap-and-trade mechanism to accelerate the application of LID in stormwater systems

In Brazilian cities, urban stormwater management is considered the least regulated and funded water service in comparison to water supply and wastewater collection and treatment. The lack of proper regulation and funding mechanism results in poor drainage services, which impacts water quality and often results in flooding, with negative impacts to society and the environment. One alternative to address these issues is the implementation of low-impact development (LID). Such approaches, however, suffer from uncertain effectiveness, high implementation and operational costs, low level community involvement in project decisions, poor technical standards and economic incentives. In this work, we focused on understanding how urban typology influences the selection of stormwater systems integrated to LID. To do so, we explore how economic tools may contribute to the implementation of effective LID systems that favor the well-being and share social and environmental benefits among households and communities. In specific, we evaluate a trading of environmental licenses. The variety of local characteristics of urban areas and municipalities requires solutions that combine environmental, socio and economic aspects. We argue that successful implementation of LID for stormwater management still requires robust legislation and economic tools.

Designing resilient public spaces in Het Hogeland: Adaptive approaches for urban water cycle

This paper introduces an integrated methodology for public space design in Het Hogeland municipality, combining climate adaptation, cultural heritage, and social well-being. The approach is structured around the “Analyse – Ambition – Action” framework and incorporates four ambition levels: maintain, optimize, strengthen, and transform. Design principles are guided by a value compass balancing six dimensions: spatial quality, health and well-being, mobility, economy, climate, and environment. Representative profiles of spatial typologies—such as streets, squares, parks, roads, and harbors—include phased strategies (“Now, Soon, Later”) to support adaptive implementation. A dedicated focus is placed on the water chain (waterketen) during the Analyse phase, where future hazard scenarios, legal frameworks, and adaptation measures were assessed and categorized per ambition level to inform integrated design principles

The methodology is linked to the Public Space Program, which provides the municipal council with a forward-looking perspective through designed profiles that integrate measures from multiple disciplines. This program aims to inspire future designers in this program by aligning spatial quality with climate resilience and community needs.

Findings emphasize systemic integration and participatory processes as key to resilient and inclusive public spaces. The approach offers a scalable model for international knowledge exchange on urban planning and governance, with a focus on climate adaptation in response to increasing climate risks and extreme weather events (IPCC, 2023).
