The Millennium Development Goals and Agenda 21 objectives have generated international research initiatives in the emerging field of urban agriculture (UA); these efforts in productive growing and food production in the urban domain are gaining pre-eminence. UA was first coined in the 80s by agro-economists who recognized informal gardening practices in southern cities (Ba et all), but it no longer is uniquely associated to the South. UA includes a broad rage of activities: the cultivation of plants, medicinal and aromatic herbs, fruit trees, and the raising of animals, poultry and fish to support the household economy, the site's ecology, as well as social and cultural activities. Thus, UA cuts across multiple disciplines - such as development, urban geography, food security, city planning, landscape architecture, urban design, housing, farming and agronomy - all of which are touched upon by the academic and professional contributors in this special issue of Open House International.
