reforestation

Reforestation according to the IPCC means the "conversion to forest of land that has previously contained forests but that has been converted to some other use".IPCC, 2022: [https://www.ipcc.ch/report/ar6/wg3/downloads/report/IPCC_AR6_WGIII_Annex-I.pdf Annex I: Glossary] [van Diemen, R., J.B.R.

According to FAO terminology, reforestation is defined as the re-establishment of forest through planting and/or deliberate seeding on land classified as forest.

Afforestation on the other hand means establishing new forest on lands that were not forest before (for example, abandoned agriculture).{{Cite book |url=http://www.fao.org/3/I8661EN/i8661en.pdf |title=Terms and definitions – FRA 2020 |publisher=FAO |year=2018 |location=Rome |archive-url=https://web.archive.org/web/20190809045851/http://www.fao.org/3/I8661EN/i8661en.pdf |archive-date=2019-08-09 |url-status=live}} It is the process of restoring and recreating areas of woodlands or forests that may have existed long ago but were deforested or otherwise removed at some point in the past or lacked it naturally (for example, natural grasslands).{{Cn|date=November 2024}}

Reforestation is not only used for recovery of accidentally destroyed forests. In some countries, such as Finland, many of the forests are managed by the wood products and pulp and paper industry. In such an arrangement, like other crops, trees are planted to replace those that have been cut. The Finnish Forest Act from 1996 obliges the forest to be replanted after felling.{{cite web |url= https://www.metsakeskus.fi/oikeudet-ja-velvollisuudet |title= Oikeudet ja velvollisuudet |publisher= Metsäkeskus (Forest Center) |language= fi |trans-title= Rights and responsibilities |access-date= 7 July 2020}} In such circumstances, the industry can cut the trees in a way to allow easier reforestation.{{Cn|date=November 2024}}

Reforestation, if several indigenous species are used, can provide other benefits in addition to financial returns, including restoration of the soil, rejuvenation of local flora and fauna, and the capturing and sequestering of 38 tons of carbon dioxide per hectare per year.{{Cite book|last=Henkel|first=Marlon|url=https://books.google.com/books?id=s2HxCQAAQBAJ&q=Reforestation,+of+several+indigenous+species+are+used,+can+provide+other+benefits+in+addition+to+financial+returns,&pg=PA126|title=21st Century Homestead: Sustainable Agriculture III: Agricultural Practices|date=22 February 2015|publisher=Lulu.com|isbn=978-1-312-93975-2|pages=126|language=en}}

{{see also|Deforestation and climate change}}There are four primary ways in which reforestation and reducing deforestation can increase carbon sequestration and thus help with climate change mitigation. First, by increasing the volume of existing forest. Second, by increasing the carbon density of existing forests at a stand and landscape scale.{{Cite journal |last1=Thomas |first1=Paul W. |last2=Jump |first2=Alistair S. |date=2023-03-21 |title=Edible fungi crops through mycoforestry, potential for carbon negative food production and mitigation of food and forestry conflicts |journal=Proceedings of the National Academy of Sciences |language=en |volume=120 |issue=12 |pages=e2220079120 |bibcode=2023PNAS..12020079T |doi=10.1073/pnas.2220079120 |doi-access=free |issn=0027-8424 |pmc=10041105 |pmid=36913576}} Third, by expanding the use of forest products that will sustainably replace fossil-fuel emissions.

Plantation forests are intensively managed, composed of one or two species, even-aged, planted with regular spacing, and established mainly for productive purposes. Other planted forests, which comprise 55 percent of all planted forests, are not intensively managed, and they may resemble natural forests at stand maturity. The purposes of other planted forests may include ecosystem restoration and the protection of soil and water values.{{cite web |title=Global Forest Resource Assessment 2020 |url=http://www.fao.org/forest-resources-assessment/2020/en/ |access-date=20 September 2020 |website=www.fao.org |language=en}}

Plantation forests cover about 131 million ha, which is 3 percent of the global forest area and 45 percent of the total area of planted forests.

Over 90% of the world's forests regenerate organically, and more than half are covered by forest management plans or equivalents.{{Cite book |last=Bank |first=European Investment |url=https://www.eib.org/en/publications/20220173-forests-at-the-heart-of-sustainable-development |title=Forests at the heart of sustainable development: Investing in forests to meet biodiversity and climate goals |date=2022-12-08 |publisher=European Investment Bank |isbn=978-92-861-5403-4 |language=EN}}{{Cite web |last=Martin |title=Forests, desertification and biodiversity |url=https://www.un.org/sustainabledevelopment/biodiversity/ |access-date=2023-01-30 |website=United Nations Sustainable Development |language=en-US}}

Planting new trees often leads to up to 90% of seedlings failing. However, even in deforested areas, existing root systems often exist. Growth can be accelerated by pruning and coppicing where a few branches of new shoots are cut and often used for charcoal, itself a major driver of deforestation. Since new seeds are not planted, it is cheaper. Additionally, they are much more likely to survive as their root systems already exist and can tap into groundwater during harsher seasons with no rain.Archived at [https://ghostarchive.org/varchive/youtube/20211211/2H-fKmbompo Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20200914171901/https://www.youtube.com/watch?v=2H-fKmbompo&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web |date=27 May 2019 |title=Africa's underground forest |url=https://www.youtube.com/watch?v=2H-fKmbompo |access-date=31 July 2020 |publisher=DW News}}{{cbignore}} While this method has existed for centuries, it is now sometimes referred to as farmer-managed natural regeneration{{cite web |date=11 February 2020 |title=In Semi-Arid Africa, Farmers Are Transforming the "Underground Forest" Into Life-Giving Trees |url=https://ensia.com/features/in-semi-arid-africa-farmers-are-transforming-the-underground-forest-into-life-giving-trees/ |access-date=31 July 2020}} or assisted natural regeneration.{{Cite web |date=2021-07-15 |title=What is assisted natural regeneration and where does it work? |url=https://www.weforum.org/agenda/2021/07/benefits-assisted-natural-regeneration/ |access-date=2023-10-26 |website=World Economic Forum |language=en}}{{Cite journal |last1=Chazdon |first1=Robin |last2=Calixto |first2=Bruno |last3=Oliveira |first3=Mariana |last4=Messinger |first4=Jared |last5=Alves |first5=Julio |last6=Calmon |first6=Miguel |last7=Anderson |first7=Will |date=March 2022 |title=The Benefits and Power of Assisted Natural Regeneration |url=https://www.wri.org/insights/what-assisted-natural-regeneration-benefits-definition |journal= |language=en}}

Policies that promote reforestation for incentives in return have shown promising results of being an effective and motivative concept to re-plant globally on a mass scale.{{Cite journal |last1=Ruseva |first1=Tatyana B. |last2=Evans |first2=Tom P. |last3=Fischer |first3=Burnell C. |date=2015-05-15 |title=Can incentives make a difference?

Some incentives for reforestation can be as simple as a financial compensation. A compensated reduction of deforestation approach has been proposed which would reward developing countries that disrupt any further act of deforestation: Countries that participate and take the option to reduce their emissions from deforestation during a committed period of time would receive financial compensation for the carbon dioxide emissions that they avoided.{{Cite journal |last=Streck |first=C. |author2=S.M. Scholz |year=2006 |title=The role of forests in global climate change: whence we come and where we go |journal=International Affairs |volume=82 |issue=5 |pages=861–879 |doi=10.1111/j.1468-2346.2006.00575.x}}{{rp|875}} To raise the payments, the host country would issue government bonds or negotiate some kind of loan with a financial institution that would want to take part in the compensation promised to the other country. The funds received by the country could be invested to help find alternatives to the extensive cutdown of forests. This whole process of cutting emissions would be voluntary, but once the country has agreed to lower their emissions they would be obligated to reduce their emissions. However, if a country was not able to meet their obligation, their target would get added to their next commitment period. The authors of these proposals see this as a solely government-to-government agreement; private entities would not participate in the compensation trades.{{rp|876}}

Another emerging revenue source to fund reforestation projects deals with the sale of carbon sequestration credits, which can be sold to companies and individuals looking to compensate their carbon footprint. This approach allows for private landowners and farmers to gain a revenue from the reforestation of their lands, while simultaneously benefiting from improved soil health and increased productivity.{{Cite journal |last1=Shabman |first1=Leonard |last2=Zepp |first2=Laura |last3=Wainger |first3=Lisa |last4=King |first4=Dennis |date=2002 |title=Incentives for reforestation of agricultural land: What will a market for carbon sequestration credits contribute? |url=https://www.jstor.org/stable/44503226 |journal=American Journal of Alternative Agriculture |volume=17 |issue=3 |pages=116–124 |doi=10.1079/AJAA200213 |issn=0889-1893 |jstor=44503226|url-access=subscription }}

Alongside past financial incentive strategies, reforestation tax benefits have been another way the government has encouraged companies to promote reforestation tactics through the promises of a tax break.{{Cite web |last=Shutterstock |first=Credit |date=2020-02-04 |title=What Are Reforestation Tax Benefits? |url=https://mylandplan.org/content/what-are-reforestation-tax-benefits |access-date=2022-05-14 |website=My Land Plan |language=en}}

As many landholders seek to earn carbon credits through sequestration, their participation also encourages biodiversity and provides ecosystem services for crops and livestock.{{cite journal |last1=Andres |first1=Samantha |date=20 September 2022 |title=Defining Biodiverse Reforestation: Why It Matters for Climate Change Mitigation and Biodiversity |journal=Plants, People, Planet |volume=5 |pages=27–38 |doi=10.1002/ppp3.10329 |s2cid=252418294 |doi-access=free |hdl-access=free |hdl=20.500.11820/fa87acb7-8982-43d9-bf03-ab700dd168d8}}

Reforesting sometimes results in extensive canopy creation that prevents growth of diverse vegetation in the shadowed areas and generating soil conditions that hamper other types of vegetation. Trees used in some reforesting efforts (for example, Eucalyptus globulus) tend to extract large amounts of moisture from the soil, preventing the growth of other plants. The European Commission found that, in terms of environmental services, it is better to avoid deforestation than to allow for deforestation to subsequently reforest, as the former leads to irreversible effects in terms of biodiversity loss and soil degradation.{{cite web|title=Press corner|url=https://ec.europa.eu/commission/presscorner/detail/en/MEMO_08_632|access-date=28 September 2020|website=European Commission – European Commission|language=en}}

A debated issue in managed reforestation is whether the succeeding forest will have the same biodiversity as the original forest. If the forest is replaced with only one species of tree and all other vegetation is prevented from growing back, a monoculture forest similar to agricultural crops would be the result. However, most reforestation involves the planting of different selections of seedlings taken from the area, often of multiple species.{{cite web |title=Archived copy |url=http://kennethmarendefoundation.com/index.php/reforestation-problem |url-status=dead |archive-url=https://web.archive.org/web/20141111185724/http://kennethmarendefoundation.com/index.php/reforestation-problem |archive-date=2014-11-11 |access-date=2013-03-27}}{{Citation |author1=Goosem, Stephen P |title=Repairing the rainforest |publication-date=2013 |year=2013 |edition=2 |publisher=Wet Tropics Management Authority; [Tarzali, Queensland] : Biotropica Australia |isbn=978-1-921591-66-2 |author2=Tucker, Nigel I.

Lots of plantation are being carried out in the Indian continent but the survivability is very poor especially for massive plantations, with less than 20% survivability rate. To improve the forest cover and to achieve the national mission of forest cover of 33%, there is a need to improve the methods of plantation. Rather than mass planting, there is a need to work on performance measurement & tracking of trees growth. Taking this into consideration, a non-profit organization [http://www.ekkadam.org Ek Kadam Sansthan] in Jaipur is leading the development of a module of mass tracking for plantations.

Agroforestry would affect the agriculture and atmosphere in Thailand in numerous ways. By planting a combination of different tree species, these trees are able to change the microclimatic conditions. Nutrient cycling also occurs when trees are incorporated in the agricultural system. It is also probable that the soil erosion that occurred as a result of deforestation can be mediated when these trees are planted.

The "doctrine of coniferous sowing" spread widely through forestry regulations and other writing at the time.

Reforestation is required as part of the federal forest law. 31% of Germany is forested, according to the second forest inventory of 2001–2003. The size of the forest area in Germany increased between the first and the second forest inventory due to forestation of degenerated bogs and agricultural areas.{{cite web |title=Grußwort – Bundeswaldinventur |url=http://www.bundeswaldinventur.de |work=bundeswaldinventur.de}}

In the 1940s, more than 75% of the country was covered in mostly tropical rainforests and other indigenous woodlands. Between the 1940s and 1980s, extensive, uncontrolled logging led to severe deforestation. By 1983, only 26% of the country had forest cover. Realizing the devastation, policymakers took a stand. Through a continued environmental focus they were able to turn things around to the point that today forest cover has increased to 52%, two times more than 1983 levels.

An honorable world leader for ecotourism and conservation, Costa Rica has pioneered the development of payments for environmental services. Costa Rica's extensive system of environmental protection has been encouraging conservation and reforestation of the land by providing grants for environmental services. The system is not just advanced for its time but is also unparalleled in the world. It received great international attention.

Costa Rica doubled its forest cover in 30 years using its system of grants and other payments for environmental services, including compensation for landowners.

Approximately 59% of Peru is covered by forest.{{Cite web |last=Vizzuality |title=Peru Deforestation Rates & Statistics {{!}} GFW |url=https://www.globalforestwatch.org/country/PER/ |url-status=dead |archive-url=https://web.archive.org/web/20180310072536/http://www.globalforestwatch.org/country/PER |archive-date=2018-03-10 |access-date=2022-05-13 |website=www.globalforestwatch.org |language=en}} A history of political turmoil and the government's inability to enforce environmental regulations has led to the degradation of the forest and environment in Peru. A military coup in 1968 caused a loss of economic mobility in the Talara region and sparked a boom in illegal logging due to the lack of alternative economic opportunities.{{Cite web |date=August 2020 |title=Engineering For People Design Brief |url=https://www.ewb-uk.org/wp-content/uploads/2020/09/EcoSwell-Design-Brief-2020-A4.pdf. |website=EcoSwell}} Illegal mining and logging operations are responsible for a great deal of Peru's deforestation and environmental damage.{{Cite journal |last=Damonte |first=Gerardo H. |date=2016 |title=The "Blind" State: Government Quest for Formalization and Conflict with Small-Scale Miners in the Peruvian Amazon: The "Blind" State |url=https://onlinelibrary.wiley.com/doi/10.1111/anti.12230 |journal=Antipode |language=en |volume=48 |issue=4 |pages=956–976 |doi=10.1111/anti.12230|url-access=subscription }} The Peruvian government has not been able to enforce an environmentally conscious mining formalization plan to protect the Amazon forest in the Madre de Dios region. The 1980s were known in Peru as the "lost decade" due to a nationwide internal conflict and severe economic crisis almost destroying the country and resulting in the state losing control over several regions. Many areas in Peru, including Madre de Dios, had no state presence until the government initiated a movement to 'conquer and populate the Amazon,' with the hopes of minimizing illegal and informal mining operations that had expanded in the region and were polluting the Amazonian rivers and the destroying of its forests.

Reforestation initiatives have expanded in the country since. In Peru, reforestation is essential to preserving the livelihoods of rural communities because much of the population relies on the forest in some way.{{Cite journal |last=VonZabern |first=Karl |date=2018 |title=From Protests to Policy: How the Institutionalization of Indigenous Movements Affects Environmental Policy Related to Resource Extraction in Peru, Ecuador and Bolivia |url=https://cdr.lib.unc.edu/concern/honors_theses/8p58pj16x |archive-url=https://web.archive.org/web/20200301015518/https://cdr.lib.unc.edu/concern/honors_theses/8p58pj16x |url-status=live |archive-date=1 March 2020 |journal=Carolina Digital Repository}} Deforestation also disproportionally affects indigenous communities in Peru, which is why reforestation efforts are essential for the protection of many communities' livelihoods.{{Cn|date=November 2024}}

One plan in this region, called Great Green Wall (Africa), involves planting a nine-mile width of trees on the Southern Border of the Sahara Desert for stopping its expansion to the south.{{Cite web |last=Mohammed |first=Omar |date=22 December 2015 |title=African countries are building a "Great Green Wall" to beat back the Sahara desert |url=https://qz.com/africa/579682/african-countries-are-building-a-great-green-wall-to-beat-back-the-sahara-desert/ |website=Quartz Africa}} However, this is more of an afforestation project than a reforestation one.{{Cn|date=November 2024}}

• Many companies are trying to achieve carbon offsets by nature-based solutions like reforestation, including mangrove forests and soil restoration. Among them are Microsoft and Eni. Increasing the forest cover of Earth by 25% will offset the human emissions in the last 20 years. In any case it will be necessary to pull from the atmosphere the {{CO2}} that already have been emitted. However, this can work only if the companies will stop new emissions and stop deforestation.{{cite news |last1=Hook |first1=Leslie |date=28 July 2020 |title=Business turns to nature to fight climate change |agency=Financial Times |url=https://www.ft.com/content/7d940587-4502-4468-acea-a67b7bf6a523 |url-access=subscription |access-date=28 July 2020 |archive-url=https://ghostarchive.org/archive/20221210/https://www.ft.com/content/7d940587-4502-4468-acea-a67b7bf6a523 |archive-date=2022-12-10}}
