Habitat

ORG - The place or type of site where an organism or population naturally occurs.

(UNEP, 1992, Convention on Biological Diversity. United Nations Environment Programme.)

 

Harvest year

LEG - Means the calendar year in which the harvest begins.

(EU, 2011, Regulation (EU) No 1337/2011 of the European Parliament and of the Council of 13 December 2011 concerning European statistics on permanent crops and repealing Council Regulation (EEC) No 357/79 and Directive 2001/109/EC of the European Parliament and of the Council. OJ L347, 30.12.2011, pp. 7-20.)

 

Harvested area

LEG - It is the part of the cropped area that is harvested. It can, therefore, be equal to or less than the cropped area.

(EU, 2009a, Regulation (EC) No 543/2009 of the European Parliament and of the Council of 18 June 2009 concerning crop statistics and repealing Council Regulations (EEC) No 837/90 and (EEC) No 959/93, OJ L167, 29.06.2009, pp. 1-11.)

 

ORG - (GLO) Data refer to the area from which a crop is gathered. Area harvested, therefore, excludes the area from which, although sown or planted, there was no harvest due to damage, failure, etc. It is usually net for temporary crops and sometimes gross for permanent crops. Net area differs from gross area insofar as the latter includes uncultivated patches, footpaths, ditches, headlands, shoulders, shelterbelts, etc. If the crop under consideration is harvested more than once during the year as a consequence of successive cropping (i.e. the same crop is sown or planted more than once in the same field during the year), the area is counted as many times as harvested. On the contrary, area harvested will be recorded only once in the case of successive gathering of the crop during the year from the same standing crops. With regard to mixed and associated crops, the area sown relating to each crop should be reported separately. When the mixture refers to particular crops, generally grains, it is recommended to treat the mixture as if it were a single crop; therefore, area sown is recorded only for the crop reported.

Harvested production

ORG - Excludes harvesting losses and production not harvested for various reasons. Harvested production is one of the three main concepts of production (and yield) used by countries when reporting to FAO.

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

 

Hemicellulose

DIC - Any of a group of complex carbohydrates that, with other carbohydrates (e.g.,pectins), surround the cellulose fibres of plant cells. The most common hemicelluloses contain xylans (many molecules of the five-carbon sugar xylose linked together), a uronic acid (i.e.,sugar acid), and arabinose (another five-carbon sugar). Hemicelluloses have no chemical relationship to cellulose.

(Encyclopædia Britannica, 2015, https://www.britannica.com/, accessed 23 September 2015.)

 

Heterotroph

STL - Organisms that obtain their material and energy needs from organic compounds produced by other organisms.

(Richmond, A., 2004, Handbook of Microalgal Culture: Biotechnology and Applied Phycology, Amos Richmond (editor), 588 pp, Wiley-Blackwell.)

 

Homogenization [ALG]

STL - Process that makes a mixture the same throughout the entire substance.

(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.)

 

Human toxicity - cancer

ECP - Impact category that accounts for the adverse health effects on human beings caused by the intake of toxic substances through inhalation of air, food/water ingestion, penetration through the skin insofar as they are related to cancer.

(EC, 2013a, Commission Recommendation of 9 April 2013 on the use of common methods to measure and communicate the life cycle environmental performance of products and organisations. OJ L124, 04.05.2013, pp. 1-210.)

 

Human toxicity - non cancer

ECP - Impact category that accounts for the adverse health effects on human beings caused by the intake of toxic substances through inhalation of air, food/water ingestion, penetration through the skin insofar as they are related to non-cancer effects that are not caused by particulate matter/respiratory inorganics or ionising radiation.

(EC, 2013a, Commission Recommendation of 9 April 2013 on the use of common methods to measure and communicate the life cycle environmental performance of products and organisations. OJ L124, 04.05.2013, pp. 1-210.)

 

Hydrotreated vegetable oil (HVO)

LEG - Vegetable oil thermochemically treated with hydrogen.

(EU, 2009c, Directive 2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the promotion of the use of energy from renewable sources and amending and subsequently repealing Directives 2001/77/EC and 2003/30/EC,OJ L 140/16, 05.06.2009.)
