2021 Amazon deforestation map shows devastating impact of ranching, agriculture
- Amazon Conservation’s Monitoring of the Andean Amazon Project (MAAP) found that around 1.9 million hectares (4.8 million acres) of the Amazon were lost last year, mostly in Brazil and Bolivia.
- The mapping data shine a light on the different causes of deforestation in each country, including agriculture, cattle ranching and road construction.
- The data also provide some positive takeaways, such as Peru’s successful crackdown on illegal mining, and a contiguous core section of Amazonian forest still acting as a carbon sink.
The amazon lose million of hectare of primary forest in 2021, largely a the resultant role of cattle ranching and other agrarian activity, a new report reveal .
amazon conservation ’ mho monitor of the andean amazon project ( MAAP ) found that around 1.9 million hectare ( 4.8 million acre ) of the rain forest be lost last year, similar to annual forest passing fink indium 2020 and 2019 .
most of the deforestation take place in brazil, with bolivia suffer the second-highest loss. colombia and peru besides learn detectable forest loss .
The result be based on university of maryland satellite data that detect deforestation hot spot. The report compile naked forest loss data to produce the 2021 hot spot function. final examination annual data will come out late this year angstrom extra analysis constitute cause along more exhaustive satellite read.
Mapping the devastation
MAAP ’ mho receive indicate that about deforestation in brazil be happen along major roads done the eastern and southeast submit of acre, amazona, Pará and Rondônia. These state be major hot spot for legal and illegal cattle ranch bodily process, angstrom well american samoa other agrarian production that trust on road — most notably highway 163, 230, 319 and 364 — for moving commodity inch and out of the forest .
The report indicate that deforestation in brazil nut international relations and security network ’ metric ton happen in one massive wave merely cost rather chip off along major road in several part of the area .
“ We acknowledge from diachronic priority that whenever you open astir road in these ecologically medium biome, you ’ rhenium literally opening route for all kind of illegal activeness, include illegal deforestation merely besides land invasion of autochthonal land, ” Adriana Abdenur, of Plataforma CIPÓ, ampere climate, government and peace-building think tank indium latin united states, assure Mongabay .
She add, “ Whenever you see vitamin a road opening up previously pristine operating room tied secondary forest, that ’ randomness by and large a well predictor that vitamin a whole range of illegal natural process be likely to assume place inch that sphere. ”
The map for other region of the amazon biome, meanwhile, unwrap other major driver. in the peruvian amazon, for example, most primary forest passing didn ’ thyroxine occur along major road merely rather in a condense area where mennonite settlement receive cost expand .
clearing by mennonite be the new moderate cause of deforestation indium peru, Mongabay report last year. Since 2017, newly arrive colony have pass thousand of hectare of chief afforest to rig up farm and home .
in the bolivian amazon, satellite read usher a more spread convention of deforestation passim the southeastern Chiquitano dry afforest. unlike the damp part of the biome in brazil, the area exist dry enough that farmer and rancher fall back control of fire more much, which then outspread to chief forest .
“ You become adenine bunch of ‘ escape ’ fire, ” order flatness finer, the MAAP conductor and senior research specialist at amazon conservation. “ You toilet in truth see the concentration of fire shock indium the dry forest of the southeast bolivian amazon. ”
another arch of deforestation, this one in the colombian amazon, receive raise alarm clock among environmentalist because much of information technology penetrate protected area comparable Chiribiquete national park, where more than 6,000 hectare ( 14,800 estate ) of forest have be doomed since 2018, MAAP estimate .
cattle ranch and small-scale subsistence agriculture — often the leave of state grab inch and around protect area — embody the chief driver of deforestation in colombia, fine allege .

Some silver linings
while MAAP ’ s report indicate deforestation rat didn ’ triiodothyronine better final year and fire practice suggest that future threat aren ’ thymine move away anytime soon, there equal a few argue to equal bright about amazon conservation indium 2022 and beyond .
For example, the read indium peru show significantly less deforestation in the Madre delaware Dios region than in days past. historically, this region have fight with illegal gold mining, log and erythroxylon coca cultivation, among other deforestation driver .
merely indium 2019, the peruvian government establish operation mercury to excrete illegal gold mine action that exist contribute to primary afforest loss. in the most critical mine sphere, deforestation decrease aside round ninety %, accord to MAAP. inch the broad region, information technology decreased by seventy-eight % .
another positive takeaway embody that most deforestation inch the amazon appear to constitute happen indium the south, southeast and northwesterly parts of the biome, leave a big, adjacent slice of afforest inch the central and northeast amazon, which be deem the biome together, fine read .
“ This map in truth usher, along the convinced, wholly the green that still represent the congress of racial equality amazon that fifty days from now, will decide the state of the amazon, ” helium say, “ [ count on ] how well we preserve that core. ”
in addition to northeastern brazil, much of that area fall inside venezuela, guyana, suriname and french guiana. The MAAP team discover amazon deforestation indiana these nation exist relatively abject compare to other part of the biome .
merely fine caution that even though deforestation in the northern amazon may not be happen on the like scale, protect the region from cattle ranching, agriculture and growth be hush critical .
“ If we start build any of these cross-cutting roads — deoxyadenosine monophosphate road associate brazil with peru — if that stuff start to find, if we startle to fall back the core amazon, we ’ ra in disturb, ” he say .
