Millennium Development Goal 1 calls for a reduction of 50% of the proportion of people whose income is less than one US-dollar a day and of the proportion of people who suffer from hunger between 1990 and 2015. However, during the 1990s, the percentage of people in sub-Saharan Africa living below the ‘poverty rate’ of $1 a day had risen and the number of undernourished people as well.
Studies so far have revealed that urban agriculture contributes to household food and nutritional security, the creation of informal employment, income diversification through sales of surplus produce or savings on food expenditures, and more broadly promotes urban food supply systems and, at least in potential, environmental sustainability (Mougeot 2000; Foeken et al. 2004; Brock & Foeken 2005). It is widely recognized that especially the urban poor could benefit from farming in town because of the relatively low investments needed to start the activity.
