Discuss in brief evolution of agricultural extension service system in India.

The evolution of agricultural extension services in India reflects the changing needs, priorities, and challenges of the agricultural sector over the years. Agricultural extension services play a crucial role in disseminating information, technology, and knowledge to farmers, facilitating adoption of modern agricultural practices, enhancing productivity, and promoting sustainable rural development. The evolution of agricultural extension services in India can be traced through several distinct phases:

1. Pre-Independence Era (Pre-1947):
During the pre-independence era, agricultural extension services in India were primarily focused on technology transfer and improving agricultural productivity to meet the colonial economic interests. The British colonial administration established agricultural departments, experimental farms, and research stations to introduce new crops, techniques, and technologies, primarily benefiting large landowners and commercial farmers. Agricultural extension was limited in scope and reach, and there was little emphasis on addressing the needs of smallholder farmers or promoting rural development.

2. Post-Independence Era (1947-1960s):
After independence, the Indian government recognized the importance of agricultural development for achieving food security, poverty alleviation, and rural prosperity. The Community Development Program (CDP) launched in the early 1950s aimed to promote integrated rural development through a network of block-level extension centers, village-level workers, and grassroots institutions. The National Extension Service (NES) was established to provide technical advice, training, and inputs to farmers, with an emphasis on promoting modern agricultural practices, improved seeds, fertilizers, and irrigation technologies. However, the CDP and NES largely focused on infrastructure development and top-down approaches, neglecting the participation of farmers and grassroots organizations in decision-making processes.

3. Green Revolution Era (1960s-1980s):
The Green Revolution in the 1960s brought about a paradigm shift in agricultural extension services in India, with a greater emphasis on technology-intensive farming, high-yielding varieties (HYVs), chemical fertilizers, and irrigation infrastructure. The Agricultural Universities (AUs) and Krishi Vigyan Kendras (KVKs) were established to conduct research, develop technologies, and disseminate knowledge to farmers through extension services. The Training and Visit (T&V) system introduced in the 1970s aimed to provide regular training, demonstrations, and advisory services to farmers, promoting the adoption of modern agricultural practices and technologies. However, the Green Revolution model led to ecological degradation, water scarcity, and socio-economic disparities, exacerbating inequalities and marginalizing smallholder farmers, women, and marginalized communities.

4. Participatory and Technology-Led Extension (1990s-Present):
In the wake of economic liberalization and globalization in the 1990s, agricultural extension services in India underwent a paradigm shift towards participatory approaches, farmer-centered extension, and technology-led innovations. The Agricultural Technology Management Agency (ATMA) model introduced in the early 2000s aimed to decentralize extension services, promote farmer participation, and strengthen linkages between research, extension, and farmers' organizations. The National Agricultural Innovation Project (NAIP) and the Agricultural Extension Reforms in India (AERI) initiative focused on promoting farmer-led innovation, ICT-enabled extension services, and knowledge-based agriculture. The establishment of Farmer Producer Organizations (FPOs) and Self-Help Groups (SHGs) has empowered farmers to access markets, inputs, credit, and extension services, fostering entrepreneurship and rural development.

5. Challenges and Future Directions:
Despite significant progress, agricultural extension services in India face several challenges, including inadequate funding, infrastructure, and human resources, limited coverage, and effectiveness of extension programs, uneven adoption of technologies, and sustainability of extension approaches. Addressing these challenges requires greater investment in agricultural research and extension, capacity building of extension personnel, strengthening of farmer institutions, promotion of gender-sensitive and climate-resilient agriculture, and harnessing of digital technologies and innovations for inclusive and sustainable rural development. Moving forward, agricultural extension services in India need to adopt a holistic and integrated approach that prioritizes the needs and aspirations of smallholder farmers, promotes agroecological principles, and fosters resilience, equity, and sustainability in agriculture and rural livelihoods.
