The name given to the model of decentralized planning adopted by the southern state of India is the Kerala Model. This model has gained recognition for its successful implementation of decentralized planning and has become a reference point for other regions and countries.

The Kerala Model of decentralized planning is based on the principles of grassroots democracy, people's participation, and local self-governance. It aims to empower local communities by giving them the authority and resources to plan and implement development initiatives according to their specific needs and aspirations.

The main features of the Kerala Model include:

1. People's Participation: The model emphasizes the active involvement of local communities in the planning and decision-making processes. It encourages the formation of local-level institutions, such as Village Panchayats and Ward Committees, where people can actively participate in identifying their development priorities and allocating resources accordingly.

2. Bottom-up Approach: Unlike traditional top-down planning methods, the Kerala Model follows a bottom-up approach. It starts with the identification of local-level needs and resources, which are then aggregated at higher levels to create a comprehensive development plan. This approach ensures that development initiatives are tailored to the specific requirements of each region.

3. Decentralized Resource Allocation: Under the Kerala Model, a significant portion of the state's budget is allocated to local governments, enabling them to prioritize and fund local development projects. This decentralized resource allocation ensures that funds are used efficiently and effectively, addressing the specific needs of each community.

4. Equitable Development: The Kerala Model places a strong emphasis on social justice and equitable development. It aims to bridge the gap between different social and economic groups by focusing on sectors such as health, education, and social welfare. This approach has resulted in significant improvements in human development indicators, such as literacy rates and life expectancy, in the state.

5. Participatory Planning Process: The planning process under the Kerala Model is highly participatory, involving extensive consultations with local communities, experts, and stakeholders. This inclusive approach ensures that diverse perspectives are considered, resulting in more effective and sustainable development interventions.

Overall, the Kerala Model of decentralized planning has been successful in promoting inclusive and sustainable development in the state. Its focus on people's participation, bottom-up planning, and equitable resource allocation has made it a valuable example for other regions and countries seeking to empower local communities and achieve holistic development.
