Urban Agriculture Magazine no. 23 – Sustainable Urban Nutrient Management

This Urban Agriculture Magazine looks at options for closing the nutrient loop through safe recycling of urban wastes, and argues that urban agriculture can play an important role in sustainable urban nutrient management.

Urban agriculture is a response to the increase in demand for food and the market proximity in cities. This way of producing food is highly dependent on available space, nutrients and water. While access to space and water largely depends on local conditions, farmers commonly use different organic and inorganic nutrient sources.

Also available in Spanish, Portuguese, French and Arabic.
