Mining mine qofa caalaa bosona qulqulleessa — forest loss extraction naannoo dhokataa

Footprint jechuun boolla qofa miti

Bakki albuudaa tokko bifa ifaa qaba. Pit, tailings pond, spoil heap, road bosona keessa murame. Isaan mallattoolee satellite argu fi regulator daangaa itti kaasu danda’u.

Garuu extraction lafa naannoo isaa illee jijjiira. Namoonni dhufu. Roads bosona bira ga’uu salphisu. Settlements guddatu. Agriculture bal’ata. Bakki albuudaa kaartaa irratti scar qofa miti; giddugala of gravity haaraa ta’uu danda’a.

Barruu Nature tokko garaagarummaa kana sub-Saharan Africa guutuu irratti lakkoofsaan kaa’a. Barreessitoonni bosona dense keessatti 2001–2020 kallattii albuuda-baasuun-ka’e deforestation tilmaamu; achiis places similar amma hin mined ta’in waliin wal-bira qabanii mine naannoo bosona dhabamuu dabalataa hammam akka mul’atu gaafatu. Xumura isaanii salphaa fi nama hin gammachiisne: kallattii bal’ina bakka albuudaa kutaa mul’atu qofa.

Kun climate fi biodiversity politics’f bu’aa faayidaa qabu dha, sababni isaas yaada lama frame tokko keessatti eega. Ammayyaa infrastructure fi anniisaa transition albuudota barbaadu. Garuu albuudota bakka duwwaa irraa hin dhufan. Gaaffiin qulqulluun slogan “Albuuda baasuun gaarii moo badaa” miti; guutuu baasii bosonaa amanamaan safaramaa jiraa?

Barreessitoonni maal godhan

qorannoon continent-scale forest fi land-fayyadama daataa causal-inference qophii waliin walitti makata. Barreessitoonni forested bal’inoota sub-Saharan Africa keessatti 2001–2020 mine clusters 16,627 kaartaa godhan. bosona dhabamuu gosa lama adda baasan.

Tokkoffaan kallattii albuuda-baasuun-ka’e deforestation dha: bal’ina bakka albuudaa keessatti clearing, pits, tailings ponds, spoil heaps, shafts fi amaloota Albuuda baasuun operations waliin kallattiin wal qabatan dabalatee.

Lammaffaan offsite deforestation dha: mine naannoo bosona dhabamuu, pit mataa isaa miti, garuu hundeessuu bakka albuudaa irraa ancillary sochii — agriculture, settlements, roads fi access biroo — ka’uu danda’u.

Kutaa lammaffaa tilmaamuuf barreessitoonni difference-in-differences bu’uura fayyadaman. Afaan salphaan, Albuuda baasuun jalqabu dura fi booda mine naannoo bosona dhabamuu, places similar garuu amma hin mined ta’in naannoo bosona dhabamuu waliin wal-bira qaban. Achiis mine giddugala irraa concentric fageenyawwan ilaalu: 1 km keessatti, 1–5 km, 5–10 km fi 10–20 km.

Qophii kun barbaachisaa dha, sababni isaas barruun mine bira bosona dhabamuu qofa lakkaa’aa hin jiru. hundeessuu bakka albuudaa irraa additional dhabamuu counterfactual trend unmined bal’inoota waliin wal-bira qabamee tilmaamame godhu yaala.

Maal argatan

Kallattii albuuda baasuun bosona dhabamsiisuu guddaa ture. Dense bosonoota sub-Saharan Africa keessatti barreessitoonni 2001–2020 187,070 hectares kallattii Albuuda baasuun-induced deforestation tilmaamu. Democratic Republic of the Congo, Ghana fi Côte d’Ivoire walitti 45% kallattii dhabamuu kanaa qabaatan.

Dhabamuu naannoo footprint caalaa guddaa ture. Bakki albuudaa tokko erga established ta’ee booda, 1 km keessatti cumulative deforestation waggaa kudhan booda unmined bal’inoota caalaa 0–100 safartuu irratti qabxiilee 8 ol ture. Kun deforestation saffisa absolute gap dha, 8% walbira qabamee daballii miti. Dhiibbaa fageenya waliin dadhabaa ta’e, garuu hin badne: waggaa kudhan booda qorannoon gaps dabalataa 1–5 km irratti 3.6 qabxiilee, 5–10 km irratti 1.9, 10–20 km irratti 1.1 tilmaama.

Lakkoofsi kun time-specific dha: dhiibbaawwan waggaa kudhan, immediate dhabamuuwwan miti.

Offsite/kallattii reeshiyoo nama ajaa’ibsiisa. Shallaggii adda keessatti, bal’ina bakka albuudaa’n hectare tokko kallattiin ifaa godhu hundaaf, waggaa shan keessatti offsite 33.9 hectares bosona cufaa dabalataa bade jedhanii giddugaleessa tilmaamu. Offsite dhabamuu dabalataa keessaa baay’een agricultural expansion hundeessuu bakka albuudaa’n triggered ta’e waliin wal qabate; settlement expansion illee barbaachisaa, roads share xiqqaa.

Lakkoofsi kunis time-specific dha: reeshiyoo waggaa shan. Ten-year 0-to-100-safartuu dhiibbaawwan waliin walitti makuun hin qabu.

Dhiibbaa bakka hunda tokko miti. qorannoon DRC irratti concern cimaa gabaasa, sababni isaas kallattii Albuuda baasuun footprint guddaa fi offsite dhabamuu dabalataa guddaa walitti qaba. Biyyoonni biroon walbira qabamee offsite rukuttaawwan ol’aanaa, kallattii footprints xiqqaa qabu. Commodity sadarkaa irratti, cobalt fi copper mines — albuudota batteries, electrical infrastructure fi anniisaa transition’f ijoo — total additional deforestation qorannoo tilmaamota keessatti ol’aanaa turan.

Maaliif offsite kutaan barbaachisaa dha

Environmental assessment yeroo baay’ee kallattii project daangaa irraa jalqaba. Kun hubatamuu danda’a. Pit mul’ata, permit perimeter qaba, dhaabbata infrastructure ijaaru ibsuu danda’a.

Garuu bosonoota legal boundaries qofaaf deebii hin kennan. Access fi incentives irratti deebii kennu. Mine roads, hojjettoota, money, settlements fi demand food fiduu danda’a. Kun bosona naannoo lafa ifaa gochuun salphaa, bu’a qabeessa yookaan barbaachisaa ta’e godhuu danda’a.

Kanaaf yaadni paperichaa cimaan lakkoofsa tokko miti. Garaagarummaa kallattii fi triggered dhabamuu dha.

Supply chain bal’ina bakka albuudaa qofa lakkaa’e, land-fayyadama jijjiirama extraction’n uume gadi xiqqeessuu danda’a. Environmental rukuttaa assessment lease daangaa irratti dhaabbate, bosona dhabamuu project sun carraan isaa guddaa gochuuf gargaare darbuu danda’a. Product renewable anniisaa deeggaru jechuun “ifaa” jedhamee market godhame illee maateriyaalii chain isaa ofumaan ifaa hin ta’u.

Kun maal hin mirkaneessu

• Anniisaa transition badaa dha jechuu hin agarsiisu. Ammayyaa infrastructure, energy-transition albuudota dabalatee, land-fayyadama costs guddaa qabaachuu danda’u agarsiisa.
• Mine hundi kallattii hectare tokkoof sirrii 33.9 hectares offsite dhabamuu uuma jechuu miti. giddugaleessa mine clusters hedduu irraa, project tokko tilmaama miti.

• Albuuda baasuun rukuttaawwan hunda hin haguugu. Water pollution, labor haalawwan, biodiversity fragmentation, rights conflicts fi hawaasummaa displacement ijoo safartuu forest-dhabamuu kana alatti jiru.
• World guutuu hin haguugu. Dense bosonoota sub-Saharan Africa irratti xiyyeeffata.

Ragaan hammam cimaa dha?

Direct-deforestation tilmaama irratti ragaa continental safartuu keessatti cimaa dha. qorannoon maxxanfame land-fayyadama fi forest-cover kuusaa daataa fayyadamuun bosona dhabamuu Albuuda baasuun amaloota waliin kallattii associated adda baasa.

Offsite additional dhabamuu irratti ragaa substantial dha, garuu model-based. Difference-in-differences observational daataa irraa sababa-qabeessa dhiibbaawwan tilmaamuuf qophaa’e, tasaa yaaliiwwan impossible yeroo ta’e. Barreessitoonni heterogeneity-jabaataa malleen haaraa fi alternative estimators robustness qoru. Gaarii practice dha.

Garuu bu’aa safartuu sirriitti dubbifamuu qaba. barruun Albuuda baasuun establishment qorannoo sirna guutuu keessatti bal’ina bakka albuudaa alatti additional deforestation waliin wal qabata jechuun ragaa jabaataa dha. Tree tokko tokko satellite irratti “mine irraa murame” jechuun confession miti.

Dubbisuu ummataaf banaa faayidaa qabu panic yookaan dismissal miti; safartuu discipline dha: Albuuda baasuun landscape tokko bana yoo ta’e, rukuttaa assessment fence alatti ilaalu qaba.

Maaliif barbaachisaa dha

“Clean anniisaa” jechuun maateriyaalii world dhoksuu danda’a. Solar panels, batteries, transmission sararoota, electric vehicles fi daataa centers hundi mined maateriyaalota barbaadu. Maateriyaalota keessaa muraasni bosonoota fi biodiversity waliigalaa barbaachisummaa qaban irraa dhufu.

Kun decarbonization dogoggora godha jechuu miti. Alternative — fossil-fuel dependence itti fufuu — land, air, water fi climate costs gurguddaa mataa isaa qaba. Garuu transition fossil sirna caalaa ifaa ta’uu danda’a, akka default ifaa ta’ee osoo hin taane.

Gatiin barruu kanaa geography dhokataa ignore gochuu rakkisa. Inni: pit qofa hin lakkaa’in. Forest jijjiiramoota pit naannoo lakkaa’i. Roads, farms fi settlements extraction booda dhufan lakkaa’i. Offsite deforestation environmental rukuttaa assessments, no-net-dhabamuu himannoowwan fi zero-deforestation supply chains keessatti galchi, jedha.

Kun “green albuudota gaarii” yookaan “green albuudota badaa” caalaa seenaa ga’eessa dha. Maateriyaalii basis transition consequences qaba; supply chain ofii isaa ifaa jechuun dura consequences sun mul’ataa ta’uu qabu.
