Temporary crops             

ORG - Crops are divided into temporary and permanent crops. Temporary crops are those which are both sown and harvested during the same agricultural year, sometimes more than once.

(FAO, 2001, 'Food balance sheets. A handbook, Food and Agriculture Organization of the United Nations, Rome, Italy.)

 

Temporary grass

LEG - Grass plants for grazing, hay or silage included as a part of a normal crop rotation, lasting at least one crop year and less than five years, sown with grass or grass mixtures. The areas are broken up by ploughing or other tilling or the plants are destroyed by other means as by herbicides before they are sown again. Mixtures of predominantly grass plants and other forage crops (usually leguminous), grazed, harvested green or as dried hay are included here.

(EU, 2009b, Regulation (EC) No 1200/2009 of 30 November 2009 implementing Regulation (EC) No 1166/2008 of the European Parliament and of the Council on farm structure surveys and the survey on agricultural production methods, as regards livestock unit coefficients and definitions of the characteristics, OJ L329, 15.12.2009, pp. 1-28.)

 

Toe

The tonne of oil equivalent (toe) is a unit of energy: the amount of energy released by burning one tonne of crude oil, approximately 42 GJ (as different crude oils have different calorific values, the exact value of the toe is defined by convention).

Multiples of the toe are used, in particular the megatoe (Mtoe, one million toe) and the gigatoe (Gtoe, one billion toe).

 

Total fodder

ECT (GLO) - Total fodder (from arable land) includes lucerne, green maize and cereals for silage or green fodder, grassing in rotation and other green fodder. Not included are: grassing from permanent grassland, fodder beets and other roots for fodder.

(Eurostat a, Eurostat's Concepts and Definitions Database, accessed 14 October 2016.)

 

Thinnings

DIC - A cultural treatment made to reduce stand density of trees primarily to improve growth, enhance forest health, or recover potential mortality.

(SAF, 2015, Society of American Foresters, Dictionary of Forestry, http://www.eforester.org/Search?SearchTerms=dictionnary.)

 

Total aquaculture production

ECT (GLO) - Is the sum of the total catches and aquaculture production excluding hatcheries and nurseries. Total production is recorded in the live weight equivalent of the production.

(Eurostat b, Glossary, accessed 14 October 2016.)

 

Total organic carbon (TOC)

STA - quantity of organic carbon present in a product.

- Note 1 to entry: Total organic carbon is often determined as the carbon that is converted into carbon dioxide by combustion and which is not liberated as carbon dioxide by acid treatment.

(EN 16575:2014, European Committee for Standardisation,  Technical Committee 411 (CEN TC/411), Bio-based products – Vocabulary, Mandate M/492, August 2014.)

- Note: A unit (grams of carbon) can be mentioned. Considering the general definition of “product”, counting the inorganic fraction in TOC is not always appropriate

 

Total final energy consumption

ORG (GLO) - The sum of consumption by the different end-use sectors. Total final consumption is broken down into energy demand in the following sectors: industry, transport, other (includes agriculture, residential, commercial and public services) and non-energy uses. Industry includes manufacturing, construction and mining industries. In final consumption, petrochemical feedstocks appear under industry use.

(IEA, International Energy Agency, Glossary of term, accessed 23 September 2015.)

 

Transesterification

STL - Process of exchanging the alkoxy group of a fatty acid by an alcohol. The primary method for producing biodiesel using vegetable oils or waste grease.

(Darzins, A., Pienkos, P. and Edye, L., 2010, Current status and potential for algal biofuels production. A report to IEA Bioenergy Task 39, Report T39-T2, August 2010.)

 

Transgenic

STL - Relating to the transfer of genes from one species into another.

(Delgado, C.L., Wada, N., Rosegrant, M.W., Meijer, S. and Ahmed, M., 2003, Fish to 2020. Supply and demand in changing global markets, Appendix F, WorldFishCenter Technical Report 62, International Food Policy Research Institute (IFPRI), Washinton D.C., World Fish Center, Bayan Lepas, Malaysia.) 

 

Trawling [AQU]

STL - The fishing method of dragging a net behind a boat, sometimes on the sea bottom.

(Delgado, C.L., Wada, N., Rosegrant, M.W., Meijer, S. and Ahmed, M., 2003, Fish to 2020. Supply and demand in changing global markets, Appendix F, WorldFishCenter Technical Report 62, International Food Policy Research Institute (IFPRI), Washinton D.C., World Fish Center, Bayan Lepas, Malaysia.) 

 

Triacylglycerols; Triacylglycerides; Triglycerides

STL - Simple fats or lipids consisting of glycerol esterified to three fatty acids.

(Darzins, A., Pienkos, P. and Edye, L., 2010, Current status and potential for algal biofuels production. A report to IEA Bioenergy Task 39, Report T39-T2, August 2010.)

 

Trophic level

STL - Position in the food chain.

(Delgado, C.L., Wada, N., Rosegrant, M.W., Meijer, S. and Ahmed, M., 2003, Fish to 2020. Supply and demand in changing global markets, Appendix F, WorldFishCenter Technical Report 62, International Food Policy Research Institute (IFPRI), Washinton D.C., World Fish Center, Bayan Lepas, Malaysia.)
