How will the province of South Holland change in the next 10-100 years as a result of ongoing land subsidence, and where will problems arise? These are questions that the province, which has more than 3.5 million inhabitants, has to tackle. Pressure on space is increasing. More and more people want to live and work in South Holland, even though the subsurface is generally soft and unsuitable for building without inflicting damage. After 1000 years of land subsidence in South Holland, there are more and more places where the physical system is reaching the limit. Scenario studies have shown that continuing to use land as we do now will result in major costs. If there is no change in the policy, large areas will end up facing the same difficulties. In addition, ongoing subsidence results in rapidly-increasing management and maintenance costs for urban furnishings and infrastructure, including roads and pipes. A different approach and new measures are needed to keep the costs of living and working in South Holland manageable.
