Second Project: "Green Riyadh": The Green Riyadh Project includes planting 7.5 million trees across the capital in gardens and parks, mosques, schools, academic, healthcare and public facilities in addition to King Khaled International Airport and most of roads, streets, car parking spaces, and valleys. To secure the required irrigation water for this project, new irrigation networks will be established to use recycled water which is usually being wasted in the valleys. Selected species of trees will be used to make wide shade cover. Those species will survive in Riyadh's desert environment and they will not require large amounts of water. Additionally, required support elements will be made available for this project such as: a network of nurseries to feed the project with seeds, legislation and urban standards will be developed to encourage tree planting on public and private projects, and all local community groups will be encouraged to participate in volunteer initiatives within the Green Riyadh project. --More 20:05 LOCAL TIME 17:05 GMT 0029 www.spa.gov.sa/w1070124
