Hundreds of nature reserves in densely populated areas across Europe are falling into public neglect and are threatened because of the limited resources engaged in their promotion and maintenance. Ignace Schops has realized their untapped potential and has found a way to dramatically enhance both the environmental and economic value of these areas through concerted development. In the province of Limburg, Belgium, he has piloted the first citizen movement in Europe to claim the custody of a 6,000 hectare natural reserve into a national park, leading to the compatible development of a 20,000 hectare area. In doing so, he has mobilized a new generation of entrepreneurs to create calibrated investments that foster business opportunities while supporting local ecological quality. Ignace is now using this park to anchor an economic development model adaptable to small and large nature spots and reserves in densely populated regions across Europe.
