Hoe Satellyten de Omfang fan Ûntbossing Iepenbierden
July 26, 2025 · Frisian News
New satellite monitoring shows forest loss across the tropics accelerated sharply in 2024, with Brazil and Indonesia accounting for more than half the damage. The data exposes failures by governments that promised to stop cutting.
FryskWittenskippers joegen ferline wike satellytgegevens frij dy't sjen litte dat tropiske bosken yn 2024 mei 4,1 miljoen hektare ôfnommen binne, it fluchste tempo yn op syn minst twa desennia. De sifers kamen fan Planet Labs en de Universiteit fan Maryland, mei help fan bylden mei hege resolúsje dy't boskferlies oant yndividuele kapgebieten fêstlizze. Wat de satellyten fûnen, skokte sels betûfte ûndersikers: de fernieling fersnelde nettsjinsteande wrâldwiide beloften om ûntbossing foar 2030 te stopjen.
Brazilië syn Amazoneregio ferlear ferline jier hast 40 prosint fan de totale kappte bosbegroeiing wrâldwiid. De Yndonezyske eilannen Sumatra en Kalimantan makken noch ris 20 prosint út. Beide lannen hawwe regearingen dy't binende oerienkomsten ûndertekene hawwe om it kapjen te stopjen, mar gjin fan beide fertrege. Brazilië syn nije regearing beloofde stranger hanthavenjen as har foargongers, mar satellytmonitoren betrapje yllegale houthakkers en lângrippers dy't har aktiviteiten djip yn beskerme gebieten útbrieden. Yndonezyske palmoljeplantaazjes bleaune har fersprieden oer feangrûnen, wêrby't koalstof frijkaam en habitat fernielet waard.
De satellytmetoade slacht âlde benaderingen om't it fluch wurket en gjin romte lit foar it ferfalskjen fan sifers. Ynspekteurs op it plak hawwe moannen nedich om rapporten yn te tsjinjen dy't regearingen dêrnei betwiste. Satellyten leverje elke pear dagen bylden, wêrtroch autoriteiten it skeaferslach net ferbergje kinne of har beskerringseisken opblaze kinne. Bedriuwen dy't hout of lânbouprodukten út dizze regio's keapje, fiele no druk om de satellytgegevens sels te kontrôlearjen ynstee fan offisjele ferklearringen fan korrupte amtenaren te fertrouwen.
Jild tasein foar boskbeskerming is opdroege of nearne hinne gien. Rike naasjes seinen op klimaatkonfjerinsjes miljarden ta, mar it jild kaam let by lannen oan, mei betingsten of waard opslikt troch byrokrasy. Lokale mienskippen dy't wier bosken tsjin yndringers beskermje, seagen hast neat. Underwilens bliuwe prizen foar rindfleis, palmoalje en hout heech genôch dat lâneigners it romjen winstjouwender fine as behâld, nettsjinsteande wat satellytcamera's harren betrapje.
De echte test komt takom jier as satellytkontrôle noch skerper wurdt. As regearingen dit stopje wolle, moatte se houthakkers en lângrippers ferfolgje ynstee fan boetes útdielen dy't se negearje. It útpleatsen fan troepen op it plak kostet jild en politike wil. Satellyten sjogge allinne ta.
Scientists released satellite data last week showing that tropical forests shrank by 4.1 million hectares in 2024, the fastest rate in at least two decades. The numbers came from Planet Labs and the University of Maryland, using high-resolution imagery that captures forest loss down to individual clearings. What the satellites found shocked even seasoned researchers: the destruction accelerated despite global pledges to end deforestation by 2030.
Brazil's Amazon region lost nearly 40 percent of the total forest cover removed worldwide last year. Indonesia's Sumatra and Kalimantan islands accounted for another 20 percent. Both nations have governments that signed binding agreements to halt the cutting, yet neither country slowed down. Brazil's new administration promised stricter enforcement than its predecessors, but satellite monitors caught illegal loggers and land grabbers expanding operations deep into protected areas. Indonesia's palm oil plantations continued to spread across peatlands, releasing carbon and destroying habitat in the process.
The satellite method beats old approaches because it works fast and leaves no room for fudging the numbers. Ground inspectors take months to file reports that governments then dispute. Satellites deliver images every few days, making it harder for authorities to hide the damage or inflate their conservation claims. Companies that buy timber or agricultural products from these regions now face pressure to check the satellite records themselves rather than trust official statements from corrupt officials.
Funds promised to protect forests have dried up or gone nowhere. Rich nations pledged billions at climate conferences, but the money reached countries late, with strings attached, or got swallowed by bureaucracy. Local communities that actually guard the forests against intruders saw almost nothing. Meanwhile, prices for beef, palm oil, and timber remain high enough that landowners find clearing more profitable than conservation, no matter what satellite cameras catch them doing.
The real test comes next year when satellite monitoring becomes even sharper. If governments want to stop this, they need to prosecute loggers and land grabbers instead of issuing fines they ignore. Putting boots on the ground costs money and political will. Satellites just watch.
