NEWS in brief FAOs’ AquaCrop Version 6.0 is now available Global Highlights The water sector, and the UK overall, is facing a wide range of enormous and complex challenges and is working to secure the long-term resilience of water and sewerage supplies and services. Climate change is bringing more volatile and extreme weather patterns. In just the past few years we have seen severe droughts, floods, and extremes of rainfall and cold weather. This has led to shortages and to too much water, sometimes both at once. At the same time, environmental standards are getting even tougher, particularly around the quality of our rivers and bathing waters. This requires, for example, the highest standards of water treatment and well-maintained sewer networks. Version 6.0 of AquaCrop, the crop-water productivity model developed by FAO to address food security and assess the effect of the environment and management on crop production, has now been released on the AquaCrop website. The new features of version 6.0 are: • It enhances simulation of crop performance in very dry environments. • It allows to consider the presence of gravel as an extra soil profile. • It simulates the effect of weed infestation on crop production. • The water thresholds for stomatal closure of some crops have been improved in the crop data base. • Dry beans have been calibrated and added as a new crop in the crop data base. Another big challenge facing many water companies is dealing with growth in population and housing. The UK’s population is expected to rise by 10 million by the 2030s and another 10 million by around 2050. Water UK has united industry knowledge in two key sector-wide projects, the Long Term Water Resources Planning Framework and the 21st Century Drainage Programme. These projects are helping the water sector to resolutely tackle these issues, and looking
