Integrating nature-based solutions in the urbanization process by urban agriculture: a case of Bhubaneswar city, India

Abstract

Nature-based solutions are approaches that draw inspiration from and are supported by nature, offering environmental, social, and economic benefits for enhancing urban resilience and sustainability. One of the greatest land use changes affecting the urban landscape is agricultural land conversion which affects the food security. Urban agriculture will not only generate livelihood opportunity for the urban poor but be the urban lung and heat sink, allow solid and water waste disposal and facilitate eco-cultural community bonding. A vast majority of the global urban dwellers live in the small and medium sized cities. However very little study has been done on urban agriculture in these areas although agricultural loss is more pronounced here. The objective of this paper is to examine through remote sensing data, in a time series between 2011 to 2023, the loss in agricultural land in one such smaller city- Bhubaneswar, which lies on a very fertile agricultural belt. This paper examines the decline of agricultural land in comparison to the rise in built up area within the specified timeframe and goes on to suggest a nature-based solution which makes the city self-sufficient in terms of food security. The research methodology involves mapping the spatial distribution of both the supply and demand for ecosystem services and quantifying the impact of Agriculture land use conversion on agriculture production. It concludes by deriving a framework which will identify the policy and governance interventions required so that the SDG goals 2 and 11.3 are realized.
