Selected Projects
Hydrological Modelling for Informed Water Resource Planning and Investments
Yemen faces declining agricultural productivity and rising malnutrition of people due to an extreme pressure on water resources. A basin-wide SWAT model (Soil Water Assessment Tool) was developed and provides a first estimate of the water balance and key hydrological processes.
Reducing CO2 Emissions: Model Study of Innovative Peatland Rewetting
In a feasibility study, Acacia Water surveyed the extent to which a drip infiltration system (DIS) can contribute to the rewetting of peat soils and the reduction of greenhouse gas emissions. This modeling study shows the effect of different DIS variants on groundwater levels, soil moisture, temperature, and emissions.
Thriving Rangeland Ecosystems and Water Availability in (Semi)-Arid Landscapes
Resilient water and rangeland service delivery, in arid and semi-arid lands (ASALs), is the focus of the Kenya Resilient Arid Lands Partnership for Integrated Development Plus (Kenya RAPID+). The program builds on over five-years of learning from the original Kenya RAPID program.
Nature-based Solutions for a Climate-Resilient Geul River Valley
Nature-based solutions (NbS) can reduce the likelihood of droughts and floods. For the river basin of the Geul in the Netherlands, Belgium, and Germany, the effects of 10 landscape interventions were modeled using the SWAT+ model (Soil and Water Assessment Tool Plus).
Enhancing Flood Resilience in South Sudan
South Sudan has faced prolonged and severe flooding for over many years, To strengthen the communities’ resilience to climate-related disasters, a feasibility assessment was conducted, identifying robust, evidence-based, and community-informed investments.
Water Harvesting in Jordan: Building Resilience Through 3R
Targeting Jordan’s northern regions, critical water challenges posed by climate change, population growth, and human security risks are addressed. This is done through rainwater harvesting, flood risk reduction, groundwater recharge, and reuse strategies.
Water Harvesting Explorer: Decision Support for Climate Adaptation
he Water Harvesting Explorer is a decision support webtool that helps identify sustainable small-scale water harvesting interventions in the Sahel and Horn of Africa (HoA). The online tool is based on publicly available datasets and expert-validated typologies.
Promising Pilot Study on Countering Soil Subsidence
When peat decomposes due to a drop in groundwater level, carbon dioxide is released, and soil subsides. Measures can be taken to keep the peat moist and minimize soil subsidence. Studying the effect of water infiltration.
More Successfull Drillings: Groundwater Mapping and IWRM
In the past, many wells drilled in this project area were unsuccessful or gave less yield than expected. Acacia Water delivers (shallow) groundwater mapping and Integrated Water Resources Management (IWRM) services. This approach contributes to more successful drillings.
Underground Water Storage: From Feasibility Testing to a Freshwater Cooperative
What is the feasibility and scale up potential of an innovative underground water storage system? Farmers are increasingly looking for new sources of fresh water for their agriculture to mitigate the impact of climate change.
From Degraded Slopes to Stable Watersheds: Catchment Restoration
Implementing catchment restoration activities to offset water consumption of breweries in Ethiopia. The ‘BURQAA Initiative’ focuses on soil and water conservation, hydrological monitoring, and the development of catchment management guidelines.
Is Sustainable Extraction from Small Freshwater Lenses Possible?
Can small freshwater lenses be sustainably managed so that they can be a source of water supply? A pilot study in the Dutch province Zeeland investigates the usage of water extraction from small freshwater lenses.
Double Drainage for Fresh Water: From Idea to Application
Shortage of fresh water remains a recurring challenge in the Dutch province Zeeland. In the project ‘Working together for Freshwater: demonstrating, monitoring and evaluating innovative drainage’ a new idea of double drainage has been tested in practice. The results are promising.
Drain or Elevate: Tackling Standing Water on Sports Fields
The Noordwijkse Golf Club (NGC) has been facing ponding water, forming puddles and ponds, on low-lying parts of the golf course for extended periods since 2023. This problem is caused by exceptionally high groundwater levels as a result of extreme rainfall in 2023 and 2024.
Underground Storage of Drinking Water in Oman
Water scarcity, increasingly is a problem in Oman. Rainfall is limited and irregular, and the capacity of aquifers is under pressure. Aquifer storage and recovery (ASR) could provide a cost-effective solution to Oman’s water management needs.
Managed Aquifer Recharge for Irrigation in Saline Environments
Agriculture in the coastal plains of Bangladesh faces serious challenges from seawater intrusion. A Managed Aquifer Recharge system offers a low-key low-cost method to store freshwater underground for later use. Economic assessments show a profitable business case.
