15 The Foundations and Rules of Environmental
Afforestation in Cities
15.1 Introduction
1. Governments are doing a great deal to increase afforestation, parks, public
parks, children’s playgrounds and the multiple services needed to improve the
environment.
2. Some home owners also contribute to this work.
3. Afforestation and the increase of green areas are among the most important
facilities that municipalities compete to show their care for the city especially in
areas that subjected to high temperatures, dust and sand storms.
4. This is due to the importance of plants in preserving the environment and adapting
the local climate and its diversity.
5. It is important to choose the most efficient plant species adapted to the
environment.
6. The scientific foundations of the afforestation within the cities should be followed
and the plants should be distributed in the streets and parks.
7. Be careful not to plant useless plants in the streets and parks that may cause harm
such as species that produce positive ions [168–170].
8. For afforestation foundations and controls must be observed in the gardens of the
streets and the islands and the middle and in front of houses, parks and public
parks to achieve the environmental role, climate change and health of plants and
increase environmental efficiency in cities.
15.2 Some Characteristics of Local-Friendly Species
The environmental conditions of the area to be cultivated should be identified in
order to select appropriate and suitable plant species to be cultivated for planting
When selecting these trees, the following characteristics shall be met:
a. Have a high capacity to withstand the local environmental conditions of the area
where they are grown in terms of high temperature and pollution.
b. Its high efficiency in carbon dioxide absorption.
c. The wood has a high density, which indicates efficient storage of carbon dioxide.
d. High efficiency in lowering the temperature in the surrounding air.
e. It has high resistance to insect and pathogenic infections or worms.
f. Fast and dense growth and abundant branch.
g. It has a deep root and is not spread horizontally so as not to hinder the growth of
other plants and does not affect neighboring facilities.
h. The nature of its growth, the shape of its crown and height, corresponds to the
place where it is grown and the purpose of its cultivation.
