Coastal agricultural landscapes of India sustain the lives of more than one hundred million individuals, nearly half of whom rely directly on farming, fishing, and related occupations for subsistence. The shoreline extends over 11,000 kilometers, from the fertile plains of Gujarat and Maharashtra in the west to the great river deltas of the Ganga–Brahmaputra, Mahanadi, Godavari, Krishna, and Cauvery in the east. Coastal districts comprise multiple agro-ecological zones, ranging from salt-stressed cotton and groundnut belts of Gujarat to coconut-pepper plantations across Kerala and Karnataka, and from vast kharif rice systems in Odisha and West Bengal to integrated rice–fish models across many regions.
During the last fifty years, climatic patterns along the Indian coast have changed significantly. Average temperatures have climbed by nearly one degree Celsius, sea level has been rising at more than 2.5 millimeters per year, heavy rainfall events occur more often, and cyclones are becoming stronger. These
shifts accelerate salinity intrusion, prolonged waterlogging, shoreline erosion, and storm surge risks, reducing crop productivity and threatening national food security. Irregular timing of the monsoon further disrupts cropping schedules, while repeated flooding and salt stress damage soil fertility. Economic losses are already high, with annual agricultural damage from cyclones and floods exceeding one billion United States dollars. Smallholder farmers bear disproportionate costs, losing up to fifteen percent yield in years of severe salinity. Fisheries and aquaculture also face damages surpassing two hundred million dollars annually.
To confront such risks, the government of India has established a wide adaptation framework. The National Action Plan on Climate Change coordinates several thematic missions. Among these, the National Mission for Sustainable Agriculture promotes climate-smart methods such as resilient crop varieties, micro- irrigation, and integrated farming in vulnerable zones. Complementary schemes strengthen soil management, increase assured irrigation, and provide insurance linked to weather indices. Coastal Regulation Zone norms, integrated coastal zone projects, and aquaculture rules help protect critical ecosystems, while state-level action plans adapt measures to specific vulnerabilities. Research and extension networks under the National Initiative on Climate Resilient Agriculture have deployed weather stations, piloted climate-resilient villages, and shared localized advisories through Krishi Vigyan Kendra’s and digital platforms.
Nevertheless, turning policy into practice faces repeated hurdles. Funding cycles often fail to match agricultural calendars. Data remain fragmented and responsibilities of agencies overlap. Extension resources are limited and community participation is uneven. Farm-level demonstrations show strong potential salinity-tolerant crops improve yields, rice–fish practices diversify income, subsurface drainage and solar desalination reduce salt stress, and digital advisories support timely decisions. Yet widespread adoption is constrained by insecure tenure, small and fragmented holdings, limited access to finance, and gender-based obstacles.
The financing ecosystem consists of allocations from central and state budgets, concessional credit, green bonds, blended finance mechanisms, and multilateral funds including the Green Climate Fund, the Global Environment Facility, and the World Bank. Still, innovative models such as risk-sharing arrangements, performance-linked grants, and micro-loans run by communities need scaling to reduce private sector risk and guarantee predictable support.
Key directions moving forward include aligning agriculture, water, and environmental policies through coordinated ministries, streamlining access to climate finance, embedding resilience into extension training, institutionalizing multi-stakeholder platforms, and strengthening community-driven adaptation. Core principles; community involvement, adaptive planning for multiple scenarios, fair access to technologies, diversification of livelihoods, and contingency planning in real time should guide all interventions.
The roadmap is phased: initial years 2025–2028 focus on building institutions; the second stage 2028–2032 expands and integrates proven demonstrations; the final stage 2032–2040 achieves national transformation and leadership. A specialized Adaptation Financing Unit will coordinate diverse resources, allocate based on performance, and provide fiscal transparency using digital dashboards.
By narrowing the divide between policy and practice, encouraging innovation, and enabling coastal communities, the country can safeguard agricultural productivity, protect rural livelihoods, and establish itself as a regional leader in coastal climate resilience by 2040. This strategic framework delivers a clear,
evidence-based pathway to navigate the complex challenges of a rapidly changing climate.
