What are the primary benefits of afforestation?
The primary benefits of afforestation include increased biodiversity, improved soil quality, enhanced air quality through carbon dioxide absorption, and reduced soil erosion. Additionally, it supports water cycle regulation and provides habitats for wildlife.
What is the difference between afforestation and reforestation?
Afforestation involves planting trees on land where forests have not previously existed, whereas reforestation is the process of planting trees on land that was once forested but has been depleted, with the aim of restoring the forest.
How does afforestation contribute to climate change mitigation?
Afforestation aids in climate change mitigation by sequestering carbon dioxide from the atmosphere, thus reducing greenhouse gas concentrations. Trees absorb CO2, a major contributor to global warming, during photosynthesis, thereby lowering overall carbon footprint. Additionally, forests regulate temperatures and increase land albedo, further mitigating climate change.
What species of trees are most commonly used in afforestation projects?
In afforestation projects, species such as pine (Pinus), spruce (Picea), and fir (Abies) are commonly used due to their fast growth rates and adaptability to various climates. Hardwoods like oak (Quercus) and teak (Tectona grandis) are also favoured for their longevity and economic value.
What factors must be considered when selecting a site for afforestation?
When selecting a site for afforestation, factors to consider include the local climate, soil quality, availability of water, the native flora and fauna species, land use, and the potential impact on the ecosystem and local communities. Additionally, the objectives of the afforestation project should align with the site's characteristics.
