Afforestation has many benefits. In the context of climate change, afforestation can be helpful for climate change mitigation through the route of carbon sequestration. Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion (from water and wind), floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products.Several countries have afforestation programs to increase carbon dioxide removal from forests and to reduce desertification. However, afforestation on grasslands and savanna areas can be problematic. Carbon sequestration estimates in those areas often do not include the full amount of carbon reductions in soils and slowing tree growth over time. Also afforestation can negatively affect biodiversity through increasing fragmentation and edge effects for the habitat remaining outside the planted area.

Definition

The term afforestation means establishing new forest on lands that were not forest before (e. g. abandoned agriculture). The same definition in other words states that afforestation is "conversion to forest of land that historically has not contained forests".IPCC, 2022: Annex I: Glossary [van Diemen, R., J.B.R. Matthews, V. Möller, J.S. Fuglestvedt, V. Masson-Delmotte, C.  Méndez, A. Reisinger, S. Semenov (eds)]. In IPCC, 2022: Climate Change 2022: Mitigation of Climate Change.

Types

There are three types of Afforestation:WEB, Lark, Rachel, 2023-10-02, The Importance of Afforestation,weblink 2024-01-04, Environment Co, en-US,

1. Natural regeneration (where native trees are planted as seeds; this creates new ecosystems and increases carbon sequestration).
2. agroforestry (this is essentially an agricultural activity carried out in order to grow harvestable crops such as fruits and nuts).
3. Tree plantations (carried out in order to produce wood and wood-pulp products; this can be seen as an alternative to cutting down naturally-occurring forests).

Procedure

The process of afforestation begins with site selection. Several environmental factors of the site must be analyzed, including climate, soil, vegetation, and human activity.{{Citation|last1=Duan|first1=Jie|title=Basic Theory and Methods of Afforestation|date=2021-03-10|url=https://www.intechopen.com/books/silviculture/basic-theory-and-methods-of-afforestation|work=Silviculture|editor-last=Cristina Gonçalves|editor-first=Ana|publisher=IntechOpen|language=en|doi=10.5772/intechopen.96164|isbn=978-1-83968-448-7|access-date=2021-03-25|last2=Abduwali|first2=Dilnur|doi-access=free}} These factors will determine the quality of the site, what species of trees should be planted, and what planting method should be used.After the forest site has been assessed, the area must be prepared for planting. Preparation can involve a variety of mechanical or chemical methods, such as chopping, mounding, bedding, herbicides, and prescribed burning.JOURNAL, Knapp, Benjamin O., Wang, G.

Benefits

There are several benefits from afforestation such as carbon sequestration, increasing rainfall, prevention of topsoil erosion (from water and wind), flood and landslide mitigation, barriers against high winds, shelter for wildlife, employment and alternative sources of wood products.

Climate change mitigation

Environmental benefits

Afforestation provides other environmental benefits, including increasing the soil quality and its organic carbon levels, reducing the risk of erosion and desertification.JOURNAL, Suganuma, H., Egashira, Y., Utsugi, H., Kojima, T., July 2012, Estimation of CO2 reduction amount by arid land afforestation in Western Australia,weblink 2012 IEEE International Geoscience and Remote Sensing Symposium, 7216–7219, 10.1109/IGARSS.2012.6351997, 31123240, The planting of trees in urban areas is also able to reduce air pollution via the trees' absorption and filtration of pollutants, including carbon monoxide, sulfur dioxide, and ozone, in addition to {{CO2}}.JOURNAL, Freedman, Bill, Keith, Todd, 1996-04-11, Planting trees for carbon credits: a discussion of context, issues, feasibility, and environmental benefits,weblink Environmental Reviews, en, 4, 2, 100–111, 10.1139/a96-006, Afforestation protects the biodiversity of plants and animals which allows the sustenance of ecosystems that provide clean air, soil fertilization, etc.Why is biodiversity important?

Local climate and rain

A 2017 study gives the first observational evidence that the southern Amazon rainforest triggers its own rainy season using water vapor from plant leaves, which then forms clouds above it.Jonathon S. Wright, Rong Fu, John R. Worden, Sudip Chakraborty, Nicholas E. Clinton, Camille Risi, Ying Sun, Lei Yin, Rainforest-initiated wet season onset, Proceedings of the National Academy of Sciences Aug 2017, 114 (32) 8481-8486; DOI: 10.1073/pnas.1621516114 These findings help explain why deforestation in this region is linked with reduced rainfall. A 2009 study hypothesizes that forest cover plays a much greater role in determining rainfall than previously recognized.Douglas Sheil, Daniel Murdiyarso, How Forests Attract Rain: An Examination of a New Hypothesis; BioScience, Volume 59, Issue 4, April 2009, Pages 341–347,weblink It explains how forested regions generate large-scale flows in atmospheric water vapor and further underscores the benefit of afforestation in currently barren regions of the world.

Criticism

Impact on biodiversity

Afforestation can negatively affect biodiversity through increasing fragmentation and edge effects for the habitat remaining outside the planted area. New forest plantations can introduce generalist predators that would otherwise not be found in open habitat into the covered area, which could detrimentally increase predation rates on the native species of the area. A study by scientists at the British Trust for Ornithology into the decline of British populations of Eurasian curlew found that afforestation had impacted curlew populations through fragmentation of their naturally open grassland habitats and increases in generalist predators.JOURNAL, Franks, Samantha E., Douglas, David J. T., Gillings, Simon, Pearce-Higgins, James W., 2017-07-03, Environmental correlates of breeding abundance and population change of Eurasian Curlew Numenius arquata in Britain, Bird Study, en, 64, 3, 393–409, 10.1080/00063657.2017.1359233, 2017BirdS..64..393F, 0006-3657, 89966879, free,

Surface albedo

Questions have also been raised in the scientific community regarding how global afforestation could affect the surface albedo of Earth. The canopy cover of mature trees could make the surface albedo darker, which causes more heat to be absorbed, potentially raising the temperature of the planet. This is particularly relevant in parts of the world with high levels of snow cover, due to the more significant difference in albedo between highly reflective white snow and more darker forest cover which absorbs more solar radiation.JOURNAL, Mykleby, P.

Australia

In Adelaide, South Australia (a city of 1.3 million as of June 2016), Premier Mike Rann (2002 to 2011) launched an urban forest initiative in 2003 to plant 3 million native trees and shrubs by 2014 on 300 project sites across the metro area.WEB, Projects: Adelaide Greening Strategy,weblink www.greenadelaide.sa.gov.au, Thousands of Adelaide citizens participated in community planting days on sites including parks, reserves, transport corridors, schools, water courses and coastline.

Canada

In 2003, the government of Canada created a four-year project called the Forest 2020 Plantation Development and Assessment Initiative, which involved planting 6000 ha of fast-growing forests on non-forested lands countrywide. These plantations were used to analyze how afforestation can help to increase carbon sequestration and mitigate greenhouse gas (GHG) emissions while also considering the economic and investment attractiveness of afforestation. The results of the initiative showed that although there is not enough available land in Canada to completely offset the country's GHG emissions, afforestation can be useful mitigation technique for meeting GHG emission goals, especially until permanent, more advanced carbon storage technology becomes available.JOURNAL, Dominy, S.W.J., A retrospective and lessons learned from Natural Resources Canada's Forest 2020 afforestation initiative, The Forestry Chronicle, en, June 2010, 86, 3, 339–347, 10.5558/tfc86339-3, free, On 14 December 2020, Canada's Minister of Natural Resources Seamus O'Regan announced the federal government's investment of $3.16 billion to plant two billion trees over the next 10 years.

Man-made dunes (here a liman) help keep in rainwater, creating an oasisoasisWith wood production as a main objective, monocultures of Aleppo pine were vigorously planted between 1948 and the 1970s. Following a massive collapse of this species in the 1990s, due to attacks by the insect pine blast scale, the Aleppo pine was gradually replaced by Pinus brutia.JOURNAL, Pritchard, H.

In the 1800s people moving westward in the US encountered the Great Plains – land with fertile soil, a growing population and a demand for timber but with few trees to supply it. So tree planting was encouraged along homesteads. Arbor Day was founded in 1872 by Julius Sterling Morton in Nebraska City.WEB, History at arborday.org,weblink 2024-03-04, www.arborday.org, By the 1930s the Dust Bowl environmental disaster signified a reason for adding significant new tree cover. Public works programs under the New Deal saw the planting of 18,000 miles of windbreaks stretching from North Dakota to Texas to fight soil erosion (see Great Plains Shelterbelt)weblink
