Dua set data FAO terkait tentang Tanah Organik yang Dikeringkan memberikan perkiraan:
DROSA-A: area Tanah Organik (dalam hektare) yang dikeringkan untuk aktivitas pertanian (lahan tanaman dan padang rumput yang digembalakan)
DROSE-A: estimasi karbon (C) dan dinitrogen monoksida (N2O) (dalam gigagram) dari drainase pertanian tanah organik di bawah penggunaan lahan ini.
Data tahunan tersedia dalam resolusi 0,0083333 X 0,0083333 (~1 km di
ekuator), dengan cakupan global untuk periode 1992 - 2018.
Estimasi FAOSTAT mengikuti Pedoman Panel Antarpemerintah tentang Perubahan Iklim (IPCC) dan menggunakan histosol sebagai proksi untuk keberadaan tanah organik dan peta tutupan lahan tahunan sebagai komponen yang bergantung pada waktu. Selain itu, karakteristik tanah, penggunaan lahan, dan informasi iklim diterapkan dalam analisis. Emisi karbon dapat dikonversi menjadi CO2 dengan mengalikan nilai piksel dengan rasio berat molekul karbon dioksida (CO2) terhadap C (44/12).
Tanah organik berkembang di ekosistem tanah basah. Lahan basah ini mencakup lahan gambut tropis dan boreal, rawa di lintang tinggi, pakis, dan rawa. Tanah organik mencakup
hanya 3 persen dari area daratan global, tetapi mewakili hingga
30 persen dari total karbon tanah, sehingga memainkan peran penting dalam
mempertahankan keseimbangan karbon bumi. Pertanian adalah penyebab utama pengeringan tanah organik di seluruh dunia. Drainase mengekspos bahan organik tanah organik ke kondisi aerobik yang mengoksidasi dan melepaskan sejumlah besar gas rumah kaca (GHG) berbahaya ke atmosfer.
DROSA-A dan DROSE-A adalah dasar untuk statistik negara dan regional tentang tanah organik yang dikeringkan yang disebarkan dalam tiga set data FAOSTAT (Cultivation of Organic Soils; Cropland; dan Grassland).

Food and Agriculture Organization of the United Nations (FAO) diberi mandat untuk mengumpulkan, menganalisis, menafsirkan, dan menyebarkan informasi terkait nutrisi, makanan, dan pertanian. Dalam hal ini, FAO memublikasikan sejumlah database tentang topik yang terkait dengan mandatnya, dan mendorong penggunaan database tersebut untuk tujuan ilmiah dan penelitian. Sesuai dengan prinsip keterbukaan dan berbagi yang diusulkan dalam Lisensi Data Terbuka untuk Database Statistik, dan sesuai dengan mandat FAO, data tentang emisi GHG dari aktivitas pertanian di tanah organik sebagai bagian dari FAOSTAT - database FAO tentang data Pangan dan Pertanian, tersedia gratis untuk komunitas pengguna.

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| `cropland` | ha | meters | Area of cropland organic soils (histosols) |\n| `grassland` | ha | meters | Area of grassland organic soils (histosols) |\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. In this regard, it publishes a number\nof databases on topics related to FAO's mandate, and encourages the use of\nthem for scientific and research purposes. Consistent with the principles of\nopenness and sharing envisioned under the Open Data Licensing For\nStatistical Databases, and consistent with the mandate of FAO, data on GHG\nemissions from agriculture activities on organic soils as part of FAOSTAT -\nFAO's database on Food and Agriculture data, is available free to the user\ncommunity.\n\n### Citations\n\nCitations:\n\n- FAO 2020.
