The urban development trends though often presented as if happening within closed and self-operational environments cannot be properly understood and managed without taking into account the surrounding land, namely the equally changing metropolitan landscapes. Though urban centres often act as the economic engines by creating more jobs, better medicinal supply, and more educational opportunities than the traditional countryside, they also have a large impact on the surrounding environmental quality such as water and air, on climate change, on the rapidly declining agricultural land use as well as on the biodiversity within the increasingly fragmented ecological networks to name just a few key issues.
A review of the existing initiatives in the field of urban agriculture in the context of international best practice cases will provide the basis for developing targeted policy advice and agro-buisness strategies for a more pro-active involvement of Dutch knowledge systems at the scale of European and global market perspectives. This will have to fill the gap in the wider context of urban metabolism in which food is one of the key currencies for sustainable development. Rather than just being considered a set of different innovation cases, the aim must be to develop an integrated approach towards food planning and governance at the level of metropolitan regions and thriving upon the principles of circular economy.
