Accepted Answer

Recent Rainfall Has Significantly Disrupted Salt Production in Kampot and Kep

Unusually heavy rainfall during the dry season in recent years has severely impacted Cambodia's sea salt industry, particularly in the key production areas of Kampot and Kep provinces. This persistent inclement weather has altered traditional production patterns, leading to reduced yields and increased challenges for salt producers who rely on prolonged periods of sunshine and dry conditions for the solar evaporation process.
Disrupted Production Patterns Due to Heavy Rains

Over the past five years, salt production in Kampot and Kep has been consistently affected by changing weather patterns. Heavy rainfall and high tides have frequently flooded salt ponds, a critical component of the solar evaporation technique. This disruption is directly linked to climate change, which is altering the monsoon seasons and making the weather less predictable for this traditional agricultural sector.
Significant Drop in Harvest Yields

The impact of adverse weather is clearly demonstrated by the projected harvest figures. Producers anticipate harvesting approximately 75,000 metric tonnes of salt this year. This figure represents a substantial increase from the approximately 30,000 tonnes harvested in 2025, a year when persistent rainfall severely hindered production. The disparity highlights the direct correlation between rainfall patterns and the volume of salt that can be successfully produced.
Climate Change Poses a Major Challenge

The Association of Geographical Indication Kampot-Kep Salt Producers has identified climate change as a significant threat to the industry. Salt production in these regions is entirely dependent on weather conditions, making it highly vulnerable to shifts in rainfall and temperature. The traditional harvest period, from October to May, requires extended dry spells and intense sun to evaporate seawater in shallow ponds, a process that is increasingly being compromised by unseasonal downpours.
