Os dois conjuntos de dados relacionados da FAO sobre solos orgânicos drenados fornecem estimativas de:
DROSA-A: área de solos orgânicos (em hectares) drenada para atividades agrícolas (terras agrícolas e pastagens)
DROSE-A: estimativas de carbono (C) e óxido nitroso (N2O) (em gigagramas) da drenagem agrícola de solos orgânicos sob esses usos da terra.
Os dados anuais estão disponíveis em resolução de 0,0083333 X 0,0083333 (~1 km no equador), com cobertura global para o período de 1992 a 2018.
As estimativas da FAOSTAT seguem as diretrizes do Painel Intergovernamental sobre Mudanças Climáticas (IPCC) e usam histossolos como proxy para a presença de solos orgânicos e mapas anuais de cobertura da terra como componente dependente do tempo. Além disso, características do solo, uso da terra e informações climáticas são aplicadas na análise. As emissões de carbono podem ser convertidas em CO2 multiplicando os valores de pixel pela proporção do peso molecular do dióxido de carbono (CO2) e do C (44/12).
Os solos orgânicos se desenvolvem em ecossistemas de solo úmido. Elas incluem turfeiras tropicais e boreais, pântanos de alta latitude, samambaias e charcos. Os solos orgânicos cobrem apenas 3% da área terrestre global, mas representam até 30% do carbono total do solo, desempenhando um papel importante na manutenção do equilíbrio de carbono da Terra. A agricultura é uma das principais causas da drenagem de solos orgânicos no mundo todo. A drenagem expõe a matéria orgânica dos solos orgânicos a condições aeróbicas, que oxidam e liberam grandes quantidades de gases de efeito estufa (GEE) prejudiciais na atmosfera.
DROSA-A e DROSE-A são a base para estatísticas nacionais e regionais sobre solos orgânicos drenados divulgados em três conjuntos de dados do FAOSTAT (Cultivo de solos orgânicos, Terras agrícolas e Pastagens).

A Organização das Nações Unidas para Alimentação e Agricultura (FAO) tem o mandato de coletar, analisar, interpretar e divulgar informações relacionadas à nutrição, alimentos e agricultura. Nesse sentido, ela publica vários bancos de dados sobre temas relacionados ao mandato da FAO e incentiva o uso deles para fins científicos e de pesquisa. De acordo com os princípios de abertura e compartilhamento previstos no Open Data Licensing For Statistical Databases e com o mandato da FAO, os dados sobre emissões de GEE de atividades agrícolas em solos orgânicos como parte do FAOSTAT, o banco de dados da FAO sobre dados de alimentos e agricultura, estão disponíveis sem custo financeiro para a comunidade de usuários.

DROSA-A: area of Organic Soils (in hectares) drained for agricultural\n activities (cropland and grazed grassland)\n\n2. DROSE-A: carbon (C) and nitrous oxide (N2O) estimates (in gigagrams) from\n the agricultural drainage of organic soils under these land uses.\n\nAnnual data are available at 0.0083333 X 0.0083333 resolution (\\~1 km at the\nequator), with global coverage for the period 1992 - 2018.\n\nFAOSTAT estimates follow the Intergovernmental Panel on Climate Change\nGuidelines (IPCC) and use histosols as proxy for the presence of organic\nsoils and annual land cover maps as time- dependent component. Additionally,\nsoils characteristics, land use, and climate information are applied in the\nanalysis. The carbon emissions can be converted to CO2, multiplying pixel\nvalues by the ratio of the molecular weight of carbon dioxide (CO2) to that\nof C (44/12).\n\nOrganic soils develop in wet soil ecosystems. They include tropical and\nboreal peatlands, high-latitude bogs, ferns, and mires. Organic soils cover\nglobally a mere 3 percent of the terrestrial land area but represent up to\n30 percent of the total soil carbon, thus playing an important role in\nmaintaining the earth's carbon balance. Agriculture is a major cause of\ndrainage of organic soils around the world. Drainage exposes to aerobic\nconditions the organic matter of organic soils that oxidizes releasing large\namounts of harmful greenhouse gases (GHG) to the atmosphere.\n\nDROSA-A and DROSE-A are the basis for country and regional statistics on\ndrained organic soils disseminated in three FAOSTAT datasets (Cultivation of\nOrganic Soils; Cropland; and Grassland).\n\n### Bands\n\n\n**Pixel Size**\n\n927.67 meters\n\n**Bands**\n\n| Name | Units | Pixel Size | Description |\n|----------------|-------|------------|--------------------------------------------|\n| `croplandc` | Gg | meters | C emissions from cropland organic soils |\n| `croplandn2o` | Gg | meters | N2O emissions from cropland organic soils |\n| `grasslandc` | Gg | meters | C emissions from grassland organic soils |\n| `grasslandn2o` | Gg | meters | N2O emissions from grassland organic soils |\n\n### Terms of Use\n\n**Terms of Use**\n\nThe Food and Agriculture Organization of the United Nations (FAO) is\nmandated to collect, analyze, interpret, and disseminate information related\nto nutrition, food, and agriculture.
