GREENING HOMES

Planting trees in homes is an effective way to help mitigate the effects of climate change.

With the growing global concerns about environmental degradation and rising greenhouse gas emissions, it has become essential to think of local solutions. One of the most prominent solutions is to dedicate part of the home space for tree planting.

Trees act as one of the best natural agents for air purification, as they absorb carbon dioxide, one of the gases responsible for global warming, and release oxygen in return. By planting a tree, an individual can help reduce carbon dioxide levels in the atmosphere, leading to improved air quality and reduced pollution levels.

Dr Rashid al Yahyaei, Professor, Department of Plant Sciences at the College of Science Agriculture and Marine, explains what is termed 'amateur gardening' in home gardens, public spaces, and schools. This, he says, is a positive and necessary trend that significantly contributes to improving the environment.

He emphasises that this practice represents an important step in combating climate change, as planted trees absorb carbon dioxide, which is one of the main greenhouse gases. He added that this step is not only beneficial to the environment but also provides green spaces that enhance the aesthetic appeal of homes and cities.

Al Yahyaei points out that planting in home gardens should be fruitful and of nutritional value, such as palm trees, mangoes, and lemons, which can meet family nutritional needs and contribute to achieving a level of self-sufficiency.

Regarding public gardens, he stressed the importance of utilising the diverse native plants of Oman, as it boasts more than 1,400 plant species well-suited to local climatic conditions. He emphasised that these native species require minimal water, reducing the energy consumption needed for irrigation and lowering the emissions associated with garden maintenance.

He further explained that for every tree planted in public gardens and streets, there is a native Omani counterpart, which is often more beautiful and sustainable compared to imported plants. He highlighted that native trees need little water, meaning they require less maintenance energy, making them eco-friendly and contributing to the absorption of more carbon dioxide, thus enhancing the environmental benefits of these practices.

Al Yahyaei stresses the importance of encouraging individuals to plant home gardens, not only to achieve food security but also to improve the local environment. He explained that using native plants in home gardens helps reduce emissions and energy consumption, which is a critical step in combating climate change.

Regarding individuals' awareness of the importance of addressing climate change risks through gardening and planting, Dr Al Yahyaei added, "We should not wait until we reach a stage where we are accountable for every carbon molecule we consume or release into the air."

He noted that this trend has already started to emerge in some countries and may become widespread in most nations in the coming years. Therefore, each person must be aware of the importance of reducing energy consumption and contributing to carbon absorption by expanding green spaces, whether at home or in public places.

Making tree planting part of a family’s culture can shift lifestyles towards sustainability. The planting spaces do not necessarily have to be large; even a small tree can make a tangible difference. Encouraging children to participate in the planting process and care for it helps instil environmental awareness in them from an early age.

Dedicating a small piece of land at home for planting trees is not just a simple contribution to improving the environment but an investment in a healthy future. Trees, by providing shade and cooling the air, help reduce the need for cooling devices, thus reducing electricity consumption from sources that may not be environmentally friendly. Trees also contribute to preserving biodiversity and providing shelter for small animals and birds, enhancing ecosystem stability and helps prevent the degradation of natural resources.
