Defra has published an assessment of UK and global food security. Sustainable water resources are essential but are threatened by environmental challenges.
The analysis released today provides perspectives at global and national level. Providing food for up to three billion more people worldwide by 2050 requires more efficient use of water to increase cereal yields. Yet global water productivity – crop yield per unit of water – has not been rising.
The yield is highest in Europe as a result of effective governance and operational arrangements. In the UK, Defra points out, we enjoy a high degree of food security because of our openness to trade and the ability of food retailers to switch supply in the event of disruption.
A more sustainable food chain
Complacency is not an option, however. At global level, we are told "the UK Food Security Assessment focuses on data for fertiliser and water use (along with global fish stocks)". Among the goals of UK policy Defra sets out is "a more environmentally sustainable food chain". Speaking about today's publications on the BBC, Hilary Benn, Secretary of State, underlined the importance of research in helping develop plants that need less water.
In the UK we have a well-managed and efficient water industry, overseen by regulators all of whom have a duty to work for long-term sustainability.
Water companies in England and Wales are required to prepare strategic direction statements and water resources management plans looking 25 years ahead, and detailed business plans for 2010 to 2015. Increasing water efficiency is a core aim in all these documents.
Fortunately the government and water regulator Ofwat share this aim, because the industry's success in contributing to a more sustainable environment depends in no small part on Ofwat's final determination of water prices for 2010-15, due in November, and the Secretary of State's support for water resource plans in the coming months.
Ofwat and risk - is the devil in the detail?
