Saudi Arabia's Ministry of Environment, Water and Agriculture is urging people to plant trees as a way to deal with high summer temperatures. The ministry says trees are one of the best natural ways to cool cities, improve air quality, and help the environment.
Trees lower temperatures by providing shade and reducing heat absorbed by roads and buildings. They also release water vapor, which cools the air. According to the ministry, one tree can absorb about 150 kilograms of carbon dioxide each year.
More green spaces also improve public health. They reduce stress, boost mental well-being, filter air pollutants, lower noise, and help manage rainwater. Trees also provide homes for wildlife and pollinators.
The ministry recommends planting native tree species because they are better suited to Saudi Arabia's climate and need less water. This makes tree-planting projects more sustainable.
For watering, the ministry advises doing it early in the morning or late in the evening. Using drip irrigation can cut water loss from evaporation by up to 50% compared to traditional methods. Adding organic mulch around trees helps keep soil moist, regulate soil temperature, and stop weeds.
The ministry calls tree planting a long-term investment for the environment and future generations. It says community involvement and responsible practices are key to expanding green areas and protecting natural resources.
