In a country like India where almost 60 percent of the population lives in large cities (i.e., in cities with a population of more than one lakh people) and about 30-40 percent of a city’s population is in slums, the urban areas can assume more importance as a catalyst for environmental improvement, employment generation and poverty alleviation.
Therefore, even though agriculture and urbanization are seen as typically conflicting activities, urban areas are increasingly being recognized as a realistic and desirable land-use option and as an integral part of the urban ecosystem. Hence, interest in urban areas in Kerala is growing very rapidly. In recent times, when considering the proliferation of
homes Kerala state as a whole and particularly its urban centers are witnessing major developments unseen in earlier times. Newer developments have overtaken the prominent city centers.
Along with the present urban developments, the government has also stepped in to promote the livelihood of people residing in the urban centers. Urban agriculture is now finding many takers with the proliferation of the modern concrete jungle along with phenomenal rise in day temperatures due to the lack of open spaces for plants and other greeneries. There are numerous examples of urban farming throughout the world, in countries like USA, Canada, China (with roughly 40 percent of the urban jobs in agriculture), Hong Kong, Singapore, Papua New Guinea, Zambia, Kenya, Mozambique (the capital Maputo has 30 percent area under urban agriculture) etc, which testify to the benefits derived from urban agriculture.
In cities like Berlin as many as 50,000 persons rent land to produce crops. In Dar es Salaam 68 percent of the city workers produced food in 1988. The common belief is that the future of urban agriculture is in Asia. It is true because urbanization is more rapid in the Asian countries today, than in the West.
But it is to be remembered that urban agriculture is transient in character, as it is practiced mostly on marginal/underutilized/transitional lands. Therefore, urban developments can obliterate such agriculture both within the city, as well as in the semi-urban areas. On the periphery of the cities like Trivandrum, Kochi and Kozhikode, urban agriculture can be pushed farther away from the center of the city because of urban expansion.
