  1. Treatment of cultivated biological resources in SEEA-MFA 13th Meeting of the London Group on Environmental Accounting 29 September - 3 October 2008, Brussels, Belgium Karl Schoer, consultant UNSD

  2. Objective of this paper • to introduce a solution of the issue of “cultivated crops • and trees” for the SEEA-MFA by following the principal • line of the London Group conclusions; • (b) to provide an improved presentation of the alternatives • for dealing with cultivated crops and trees in MFA accounting; • and to present the implications of the proposed approach • for other MFA modules.

  3. Material flows of extraction of non-cultivated biological resources Extraction of non-cultivated biological resources Other economy Environment Technical metabolism Biological metabolism Fuels and other produced inputs Oxygen, etc. Raw materials Natural resources Waste, waste water, etc. Air emissions, waste, etc. By-catch of fishing etc. 12.0 Products Natural inputs Residuals Internal flows

  4. Material flows of plant cultivation: “ecosystem approach” Cultivation of plants Other economy Environment Technical metabolism Biological metabolism 3.0 Fuels and other produced inputs 9.0 Oxygen and other natural inputs Carbon dioxide, water vapor 12.0 Seed, fertilizers, pesticides, irrigation water 11.2 Seed, fertilizers etc. 11.2 552.3 Carbon dioxide, natural water, soil minerals 195.1 Used biomass increase 195.1 Used biomass increase Seed, fertilizers, pesticides, irrig. water (not incorporated) 7.0 Unused biomass increase 160.0 Oxygen, water vapor 201.4 Products Natural inputs Residuals Internal flows

  5. Material flows of plant cultivation: “harvest approach” Cultivation of plants Other economy Environment Technical metabolism Biological metabolism 3.0 Fuels and other produced inputs 9.0 Oxygen and other natural inputs Carbon dioxide, water vapor 12.0 Seed, fertilizers, pesticides, irrigation water 11.2 Seed, fertilizers etc. 11.2 552.3 Carbon dioxide, natural water, soil minerals 195.1 Used biomass increase 195.1 Used biomass increase Seed, fertilizers, pesticides, irrig. water (not incorporated) 7.0 Unused biomass increase 160.0 Oxygen, water vapor 201.4 Products Natural inputs Residuals Internal flows

  6. Why Harvest approach as the standard? • (a) Dominance of the biological metabolism for cultivation • of crops, plants and trees • (b) Harmonisation with EW-MFA • (c) Analytical usefulness: • ecosystem inputs are a much less meaningful indicator • compared to crops and trees • (d) Data availability

  7. Implications of using the “harvest approach” approach EW-MFA: Change in inventories in standing crops and timber have to be introduced to the current Eurostat reporting system (but indicators will exclude change in inventories of standing timber) Other SEEA-MFA modules: General: Only non-product flows related to biological metabolisms are affected, flows related technical metabolisms remain unchanged Module on agriculture: Focus on product flows and specific residual flows, but no complete mass balancing Module on forestry: Focus on product flows and specific residual flows, but no complete mass balancing Module on water: Direct take up of natural water by cultivated plants, crops and trees is not regarded Module on waste: Unused crop residues are not regarded as waste

  8. Questions to the London Group • Do you agree that EW-MFA should be designed as a fully • integrated sub-module of SEEA-MFA (harmonization)? • Do you agree to use the “harvest approach” as the standard • concept of SEEA-MFA for reporting the material flows • of cultivation of biological resources? • Do you agree to use the “ecosystem approach” and the • “extended harvest approach” as additional concepts of • SEEA-MFA in order to meet specific circumstances or • specific analytical requirements?
