Saudi ministry highlights tree planting to combat summer heat

The Ministry of Environment, Water and Agriculture announced that trees play a key role in cooling cities, enhancing air quality, and capturing up to 150 kilograms of carbon dioxide each year.

The initiative aligns with Saudi Arabia's broader environmental goals under Vision 2030, which include increasing green cover and reducing carbon emissions.

RIYADH — Saudi Arabia's Ministry of Environment, Water and Agriculture has highlighted tree planting as one of the most effective natural solutions for mitigating high summer temperatures, citing its role in cooling urban areas, improving air quality and supporting environmental sustainability.

Trees lower temperatures through shade, reduced heat absorption by infrastructure, and transpiration that cools the air, the ministry explained. It noted that a single tree absorbs roughly 150 kilograms of CO2 per year.

The ministry added that more green areas improve public health by lowering stress, boosting mental health, filtering pollutants, reducing noise, and aiding rainwater management, while also offering habitats for wildlife and pollinators.

It urged people to choose native tree species, which are better suited to the local climate and need less water, enhancing the sustainability of afforestation efforts.

The ministry also advised following proper irrigation practices during the summer, including watering trees early in the morning or late in the evening and using drip irrigation systems, which can reduce water loss through evaporation by up to 50% compared with traditional irrigation methods.

Applying organic mulch around trees also helps retain soil moisture, regulate soil temperature and suppress weed growth, it added.

The ministry described tree planting as a long-term investment in the environment and future generations, stressing that community participation and environmentally responsible practices are essential to expanding vegetation cover, and protecting natural resources.

The ministry's emphasis on native species and efficient irrigation shows a practical approach to afforestation in arid climates. Proper tree planting can significantly mitigate urban heat island effects, which is particularly relevant as Saudi Arabia experiences extreme summer temperatures. Public participation is crucial for the success of such initiatives. Expanding green spaces also supports biodiversity and public health, while the 150 kg CO2 absorption per tree underscores the role of urban forestry in climate action.
