Case 1: Co-creation with stakeholders for a climate-proof area

Case owner: Water Authority Hollands Noorderkwartier

Water board HHNK is looking for ways to make their area climate-proof. As the water board is not on the bar to solve all problems, all stakeholders have to join and work together, from a social responsibility. But citizens and municipalities do not always take their role. How can these parties be brought into an active position for co-creation, so that they can make their own contribution for a climate-proof environment? What is needed to strengthen the responsibilities of citizens and municipalities?

Case 2: Sustainable water and sanitation services for school children in Ghana

Case owner: VEI, WaterWorX & Ghana Water Company Limited

Of all schools in low-income countries, only 51% have access to adequate water sources and only 45% have adequate sanitation facilities, according to UNICEF, while WASH facilities and hygiene education in schools contribute to inclusion, dignity and equity. In Ghana, the Ghana Water Company Limited (GWCL) wants to ensure that an additional 19 schools are provided with adequate water and sanitation services. Funds are available, intentions are there; the question is: how can GWCL (in partnership with VEI and the WaterWorx program) ensure sustainable water and sanitation for the school children in their service area?

Case 3: Effective water management in a pressure drain dominated peatland

Case owner: Water Authority Drents Overijsselse Delta

Pressure drains might be an effective solution to mitigate land subsidence in peatlands, as they can increase the ground water table in summer and lower it in winter time, thereby reducing the oxidation rate of the peat soil. However, it implies that the ground water table can be managed at a finer scale than is common at present. Water requirements may rise, the timing of water needs may change, and the farm landscape might become more diversified. How could water authorities and farmers manage such new water management measures?

Case 4: Enabling decentralized water quality management in rural communities in Tanzania

Case owner: IHE Delft

The villages of the lower Mara area, Tanzania, rely on surface water and boreholes for most of their water needs. The communities are heavily affected by declining water quality, with pollution causing health issues and impacting fisheries and agriculture. Existing initiatives for community-based environmental monitoring typically focus on generating data for authorities and science, and rural water supply schemes typically focus on water quantity. How could an autonomous and systematic water quality monitoring and water treatment be integrated into community-based management of water resources and water supply?

Case 5: Break the production chains, for a circular economy!

Case owner: Municipality of Westland

The municipality of Westland is a partner in the ‘BioBoost initiative’, which aims to stimulate a biobased development in horticulture in Europe. This case focuses on rethinking the chain for biomass (wet) residual flows, f.e. rest products of tomatoes, in the Westland hortisector. The aim is to create value and a new purpose for upscaled products. How can we make changes, in early stages of the production chain, to create an optimal result? What kind of technical solutions could be viable? And what kind of legal challenges lay ahead?

Case 6: Transforming water use in subsistence farming for climate change adaptation in Zambia

Case owner: IHE Delft

Climate change heavily affects southern Africa, with extensive droughts and torrential rains, temperature extremes, and the collapse of seasonal weather patterns. It affects the food supply of communities in Western Zambia that could historically rely on subsistence farming. Improving water supply though boreholes provides short-term relief, but is not a long-term solution. How to create an approach for water challenges in subsistence farming communities? How to tranform agricultural water use, considering all possible sources of water on the one hand, and all aspects of farming practice – what is grown, when and how – on the other?
