The coastline of Pakistan stretches for 990 kilometers along the Arabian Sea, supporting critical farming and fisheries livelihoods for more than 10 million individuals. This zone is under increasing stress from rapid sea-level rise, saltwater encroachment, and stronger cyclonic events. Within the Indus Delta, over 2.2 million acres of once-productive farmland have been abandoned as soil salinity surpassed 15 dS/m. This has forced 1.2 million people to relocate, threatening national food supplies and undermining economic resilience. Agricultural districts situated in Sindh (Thatta, Badin, Sujawal) and Balochistan (Lasbela, Gwadar) experience yield reductions of 40 to 50 percent under moderate salinity, highly variable freshwater flows worsened by upstream diversions, and localized sea-level rise of 1.1 to 2.7 millimeters annually.
The policy structure of Pakistan, based on the National Climate Change Policy of 2012, the Sindh Agriculture Policy for 2018–2030, and the forthcoming Coastal Aquaculture Strategy for 2025–2035, forms a strong platform for adaptation. Significant technological advances demonstrate promise: salt-tolerant rice lines that retain 70 percent yield under 12 dS/m salinity, barley producing 2,000 kilograms per hectare at 15 dS/m, precision irrigation that reduces water demand by up to 40 percent, and integrated rice–fish or shrimp–rice systems that enhance system productivity by 35 percent. These approaches deliver strong financial returns, with benefit-cost ratios ranging from 2:1 to 5:1. Institutions such as the Nuclear Institute for Agriculture and Biology together with provincial research stations are central to developing and distributing these innovations.
Despite strong economic incentives linked to the blue economy, which is valued at 100 billion US dollars, and transport efficiencies from CPEC infrastructure that reduce costs by nearly 30 percent, serious gaps in practice remain. Overlapping institutional responsibilities, very low funding for extension services at only 0.21 percent of agricultural GDP, and limited cooperation between federal, provincial, and local agencies restrict widespread adoption. Financing also falls short, with government adaptation budgets covering less than one-fifth of requirements and private sector contributions staying below 10 million US dollars per year.
A phased action plan for 2025 to 2040 is recommended. This involves establishing a National Coastal Agriculture Authority, expanding tailored interventions across Sindh and Balochistan, mobilizing one billion US dollars in blended financing, and deploying comprehensive monitoring and adaptive management systems. Key priorities are large-scale distribution of salt-tolerant seed, expansion of solar- powered drip irrigation, rehabilitation of karez networks, and creation of agro-processing clusters near Karachi and Gwadar. Strengthening provincial Coastal Agriculture Cells, formalizing inclusive multi-stakeholder governance mechanisms, and embedding gender-sensitive, community-based approaches will be essential to transform the coastal plains into resilient agricultural landscapes and secure livelihoods under the pressures of climate change.
