Abstract	Perishable rural produce can lose marketable quality rapidly when harvested commodities remain exposed to field heat, unsuitable packaging, mechanical damage, delayed transport, high ambient temperature, and discontinuous cooling. Conventional refrigerated warehouses can reduce these losses but are frequently inaccessible to small-scale producers because of high capital requirements, unreliable electricity supply, transportation distance, small consignment volumes, and operating costs. This study develops a conceptual–methodological framework for low-cost cold-chain innovation suited to decentralized rural produce systems. Rather than equating cold-chain development with ownership of conventional refrigerated infrastructure, the framework combines inexpensive field handling, reusable ventilated crates, shading and rapid pre-cooling, evaporative cooling, zero-energy cool chambers, modular solar-powered refrigeration, shared storage models, basic temperature monitoring, and coordinated market dispatch. Existing evidence shows that evaporative systems can lower storage temperature and preserve fresh produce without conventional refrigeration under suitable climatic conditions, while small solar-powered cold-storage designs demonstrate potential where electricity supply is unreliable. The proposed model identifies five innovation domains: heat removal, protective handling, affordable cooling, shared infrastructure, and cold-chain continuity. A scenario-based analysis compares conventional ambient handling with increasingly integrated low-cost postharvest systems. Because no primary farm or supply-chain dataset was supplied, all quantitative results are explicitly simulated and should not be interpreted as field observations. The analysis suggests that the greatest benefit arises not from one cooling technology but from preserving temperature and product quality continuously between harvest, temporary storage, aggregation, transport, and sale. The paper concludes that low-cost rural cold chains should be designed as service networks rather than isolated storage facilities, with technology selected according to crop sensitivity, climate, market distance, energy availability, utilization rate, and producer capacity.
