Food security has been a major concern in India. In 2022, the Global Food Security Index ranked India at 68th out of the 113 major countries in terms of food security. In 2023, the Global Hunger Index ranked India at 111th out of 125 countries, exacerbated by factors such as population growth, climate change, and resource constraints. In response, startups are emerging as key players in developing innovative and sustainable solutions to address food security challenges. This dissertation investigates the role of startups in promoting sustainability and tackling food security issues in India. By analysing current trends, challenges, and opportunities, the study aims to identify entrepreneurial solutions that can contribute to enhancing food security while ensuring environmental and social sustainability. Through case studies, interviews, surveys, analysis of existing policies, collecting and analysing quantitative data on key indicators related to food security, such as agricultural productivity, food distribution networks, and access to nutritious food, to assess the effectiveness of startup interventions and to gain the deep insights into the entrepreneurial ecosystem of the food industry. Through the analysis of industry dynamics and other quantitative and qualitative data using a thematic analysis framework and other relevant statistical software, this research provides in-depth actionable insights for startups, policymakers, and stakeholders to foster sustainable entrepreneurship in the Indian food sector and improve food security outcomes.
