Organic Matter Database (OMD)

Agricultural, fisheries, forestry and agro-processing activities produce large quantities of residues, by-products and waste materials every year. However, data on such residues and by-products are not readily available. We present a global organic matter database (OMD) of residues and by-products from agriculture, fisheries, forestry and related industries. The OMD is the first of its kind consolidating quantities of residues and by-products from agriculture, fisheries, forestry and allied industries globally. Residue datasets were estimated from the FAOSTAT and FishStatJ databases using prescribed equations and conversion factors.农业、渔业、林业及农产品加工业每年均会产生大量残余物、副产物与废弃物料。然而，此类残余物与副产物的相关数据往往难以便捷获取。本研究构建了一款面向农业、渔业、林业及相关行业的全球有机质数据库（Organic Matter Database，OMD）。该OMD是全球范围内首个整合农业、渔业、林业及关联行业残余物与副产物产量数据的同类数据库。本数据库的残余物数据集依托FAOSTAT与FishStatJ两大数据库，通过预设方程与转换系数估算得到。
