\textbf{Abstract}
\begin{abstract}
\normalsize{
Given the current level of global population and its trend, the irreversibility of urbanisation creates a vast requirement and demand of resources in order for global cities to exist. The impact of the growing level of people movements into the cities have increased the concern of policy makers around the world to also provide access to food to feed the urban population, so as to achieve sustainable cities and community. The methodology used to project the global food security thus far relies on correlated models, did not provide insights into the causal relationship among other variables in the system. While food security is a global and systemic challenge, systems thinking help inform the current reference mode of the urban agricultural system. Domestically produced food in the urban area comes from the city gardens, parks and rooftop plantings, which together with imports increases the supply of food. This increase in the supply of food by domestically produced ones decreases dependence on the imported food. The locally urban produced food which depends on the available land for farming however, restricts land availability for other purposes. Increasing the amount of land use for one, decreases land availability for the others and vice versa. A model shows to what extent urban agriculture can secure food supply in response to changing and growing global demand, address land constraint and feed the urban population. An analysis into what factors can influence and motivate investments into urban agriculture are addressed. A base line of current behaviour as well as projections, mutual relationship, information feedback and circular causality, associated benefits and setbacks urban agriculture may offer to different stakeholders in the short and long term will be presented.}
