The Government has a range of policies in place to mitigate the impacts of drought, including the impact on food supplies and public health:

• The Environment Agency, which has responsibility for managing water resources and protecting the environment, chairs the National Drought Group (NDG). The NDG consists of representatives from regulators such as Public Health England (PHE), the agricultural sector and water companies. This group ensures that all sectors work together and take action to manage any impacts of dry weather and drought.

• Water companies have the legal duty to supply adequate quantities of wholesome water. To fulfil their duties, water companies maintain statutory drought plans, which set out the short-term actions they will take should a drought develop. Water companies’ drought plans are published on their websites.

The impacts of drought on food supply are mitigated by the UK’s robust and reliable food industry, which is experienced in dealing with scenarios that can affect food supply, from adverse weather damaging crops to transport issues abroad. The size and diversity of the industry is a key factor in enabling the food sector to remain resilient to food supply chain disruptions. The expertise, capability, levers and resilience to plan for and respond to food supply disruption lies within the industry.

The health effects of drought are primarily indirect, including: injury, risk to public and private water supply; dust-related problems for those with pre-existing respiratory and cardiovascular disease; and impacts on mental health and wellbeing. PHE specifically plans for the risks of hot weather, including drought, in the Heatwave and Summer preparedness programme of the Heatwave Plan for England - which became operational in June 2020.

DFID has no programmes in Iran. However, DFID does provide core funding of £55 million annually to UNDP. Through our core funding, UNDP supports Iran to respond to environmental challenges, including those related to water resources.

The Government remains committed to improving our bilateral relationship with Iran. The Foreign and Commonwealth Office continues to work closely with other government departments on these and other issues concerning the UK/Iran bilateral relationship.
