Abstract: Abstract Two of the biggest global challenges for food security – phosphorus scarcity and climate change – are threatening farmers’ livelihoods, agricultural productivity and environmental integrity. In Sri Lanka, the agricultural sector is comprised largely of smallholder farmers where rain-fed rice is often a staple. Yet climate change projections indicate rice yields could drop by 40%, affecting the majority of farmers, and poverty levels could increase from 17% to 33%. At the same time, fertilisers are highly subsidized, without which farmers in this import-dependent island state would be exposed to future price fluctuations like the 800% phosphate price spike in 2008. Collaborative research between Sri Lankan and Australian researchers investigated the capacity of smallholder farmers, policy-makers and other food system stakeholders in Sri Lanka to adapt to these twin challenges via a participatory rapid integrated vulnerability assessment framework. We find that while Sri Lanka is vulnerable, there are many adaptive strategies already in place or planned. Although these strategies are not driven by climate change adaptation or phosphorus scarcity, they could be strengthened to support phosphorus and climate smart agriculture (PACSA). Sri Lanka’s food production is in the midst of a major transformation, largely driven by the President’s push for organic agriculture and organic fertilisers, waste-to-energy systems implemented through public-private partnerships, and the National Adaptation Plan for Climate Change. There are many ‘win-win’ PACSA opportunities both on- and off-farm, such as developing crop varieties that are drought-tolerant and need less phosphorus fertiliser and improved cold storage in the food value chain to reduce food losses.
