Climate Change Adaptation in Africa, Asia, and Europe with the Citizen Science Climate Scan Platform Promoting Nature-Based Solutions

There is a clear demand for a collaborative knowledge-sharing by online climate adaptation platforms that contribute to (inter)national knowledge exchange and raising awareness about climate change. Climate adaptation platforms (CAPs) can contain decision-support tools to facilitate the process of decision-making, and may include capacity building, networking, dissemination to assist planning and implementation of proven adaptation concepts such as Nature-based solutions (NBS) to mitigate floodings, drought, and heat stress. From 2014 over 6000 global climate adaptation projects have been mapped on an open source platform ClimateScan using citizen science. This chapter describes the potential of this climate adaption platform by illustrated case studies with mapped climate adaptation measures in Africa, Asia, and Europe. The case studies illustrate engagement and tangible results related to online platforms such as: the period of relevance of ClimateScan, inclusiveness and engagement of users in different stages and continents. Workshops in Indonesia illustrate the need for validation of needs from potential users before implementing CAPs. Analyzing projects in Africa showcase best management practices in water conservation and water demand management that are of interest in many other regions in the world facing drought. In Europe detailed analysis of over 3000 climate adaptation measures in relation to neighborhood typologies is inspiring urban planners and stormwater managers to design, plan, and implement climate resilient measures with more confidence. These three global examples illustrate that mapping, promoting, and sharing knowledge about implemented proven concepts is raising awareness, contribute to community-building, and accelerate climate action around the world.

Storm water flooding Amsterdam, from a quick Scan analyses to an action plan

Dealing with the issue of urban storm water flooding is becoming increasingly urgent. In the Netherlands there are no clear guidelines on the level of acceptance of urban flooding. Based on an accurate DEM, a detailed quick scan tool has been used to assess an extreme storm event in Amsterdam. The resulting flood maps for the whole of the city show where flooding is likely to occur after 60 or 100 mm of rain in one hour, as well as which buildings are at risk.Based on the results from this mapping study, Amsterdam decided to start a program to make the city rainproof (Amsterdam Rainproof). Part of the program was the validation of the model based on field research. An example of this is the use of data from the extreme storm event that occurred in Amsterdam on 28 july2014. In this paper several pilots from Amsterdam will address the relevance and effectiveness of the quick scan tool.

XRF quick-scan mapping for heavy metal pollutants in SuDS: a methodological approach

Sustainable urban drainage systems (SuDS) such as swales are designed to collect, store and infiltrate a large amount of surface runoff water during heavy rainfall. Stormwater is known to transport pollutants, such as particle-bound heavy metals, which are known to often accumulate in the topsoil. In this study, a portable XRF instrument is used to provide in situ spatial characterization of soil pollutants. The method uses portable XRF measurements of heavy metals along profiles with set intervals (1 meter) to cover the swale with cross-sections, across the inlet, the deepest point and the outlet. Soil samples are collected, and the In-Situ measurements are verified by the results from laboratory analyses. Stormwater is here shown to be the transporting media for the pollutants, so it is of importance to investigate areas most prone to flooding and infiltration. This quick scan method is time and cost-efficient, easy to execute and the results are comparable to any known (inter)national threshold criteria for polluted soils. The results are of great importance for all stakeholders in cities that are involved in climate adaptation and implementing green infrastructure in urban areas. However, too little is still known about the long-term functioning of the soil-based SuDS facilities.

Quick Scan Circular Business Models

The QuickScan CBM (Circular Business Model) offers an approach to develop a circular business model. It focuses primarily on the manufacturing industry, even though it can be used in other sectors. It consists of three parts: (1) an introduction with an explanation of backgrounds and central concepts, (2) knowledge maps of seven business models that together form a classification and (3) the actual QuickScan.An interactive application can be found at Business Model Lab. This last version is bilingual (Dutch and English). Regardless of the version, it can be used to develop a new CBM or adapt an existing business model based on a qualitative approach. The starting point is that better design and organisation of a CBM contributes to the transformation and transition towards a sustainable and circular economy.
