Some 3.5 billion people reside in urban areas. This number is projected to reach 6.3 billion by 2050, increasing from 50% to more than 70% of the world’s population. Cities are centres of creativity and economic progress but they also face many environmental challenges due mainly to air pollution and weather, climate and water-related hazard.
Competency frameworks will be introduced into the WMO Technical Regulations, which define standards and recommended practices for services and for taking observations and creating, sharing and accessing meteorological, climatologic and hydrological data. Institutions supplying education and training opportunities to the personnel of National Meteorological and Hydrological Services are also encouraged to adjust their training courses and programmes to better support the competency frameworks.
