Greening urban food systems through nature-based solutions in Bengaluru

As the field of research on green infrastructure and nature-based solutions in cities expands, the potential of urban agriculture in the production of ecosystem services remains unexplored. Beyond the benefits of increasing food supply and reducing the vulnerability of urban populations, urban food systems can be at the heart of policies to develop nature-based solutions. This project studies the potential benefits of these systems in the perimeter of Bengaluru, an Indian city with a strong heritage in terms of urban agriculture.

Taking the case study of Bengaluru, this project led by IIHS explores how and why urban food systems, in rapidly developing urban and peri-urban areas, can be seen as nature-based urban solutions that bring benefits to ecosystems and society.  

Two research questions are addressed: 

1. What is the scope and outcomes of urban agriculture for ecosystem services (including pollination) and societal well-being (such as food and nutritional security of the most vulnerable populations)?
2. How can we use different co-production pathways across the science-policy-citizen interface to scale up NBS around sustainable urban agricultural practices?

The research methodology is based on three main work packages: 

1. Synthesis of scientific knowledge on the potential of NBS and existing practices at various scales, and particularly within a chosen ward of Bengaluru with the deployment of pilot interventions;
2. Incubation and capacity building: incubating novel NBS ideas and experiments related to pollinator friendly and water conserving urban agriculture, and capacity building through the training of various stakeholder groups;
3. Scaling impact by identifying and engaging with different stakeholders, including city-level policy and decision makers, right from the start of the project to ensure the scaling of impact throughout the project.

The expected results of these projects are: 

• Academic results on sustainable urban food systems in the context of rapidly urbanizing countries from the Global South, on urban NBS experiences and their effects on ecosystem services (including pollination);
• Knowledge outputs for urban decision-makers on the integration of NBS in urban planning;
• Capacity building and teaching materials on multidisciplinary approaches to urban sustainability.  

The project is also testing nature-based solutions aimed at strengthening the resilience of food systems in Bangalore. 

The research team aims to show how nature-based solutions (NbS) can address urban water security challenges in the Global South — a topic that remains underexplored in the scientific literature, which is still largely focused on the Global North. Drawing on expert discussions and a literature review, they identify the specific characteristics of these contexts (environmental, socio-economic, governance-related, technical capacity, etc.), as well as the barriers and opportunities for implementing these solutions. The goal is to propose concrete avenues to support the more effective and equitable adoption of NbS in cities of the Global South.
