AGROVOC as Knowledge Organization Model applied to Brazilian Agricultural Intensification Processes
This paper shows the experience of using AGROVOC thesaurus as a basis and model of information and knowledge organization and domain representation applied to soybean and sugar cane agricultural intensification in Brazil. A textual corpus of about 2,5 million of words was compiled and candidate terms extracted automatically for creating an initial hierarchical conceptual map, then compared to AGROVOC terms. The results show the importance of AGROVOC as a resource to organize and represent agricultural information and knowledge, as a reference for creating new terminological products on agriculture, and open new possibilities for enrichment of AGROVOC´s Brazilian Portuguese terminologies
Investigation of the effects of rainfall (Climate Change) on pineapple production in Essequibo Tri-Lakes Area
The variability of the rainfall pattern on the Essequibo Coast can be seen as an agricultural risk.
Indigenous and other farmers who produce pineapple in the area operate using an organic methodology,
having been certified with the assistance of IICA, and have been traditionally relying on rain-fed
conditions to satisfy the moisture requirements of the crops. Since the Essequibo Coast normally
experiences two rainy periods on an annual basis, the pineapple farmers have depended upon and used
this as a source of water for their cultivation methods. Moisture availability is important to the pineapple
plant at critical periods of growth of the crop and deficits or excesses can have detrimental effects on
production.
This situation was evident owing to the fact that pineapple yields were substandard for a two-harvest
period and the crops produced were not accepted for processing by the Mainstay Pineapple Factory, as
the fruit from these crops did not satisfy the criteria for processing. The Mainstay Pineapple Factory
which depends on local pineapples from the area was not able to satisfy its AMCAR export market to
Europe and other countries. The pineapple factory lost important revenue and if the phenomenon
continues, it risks losing its market share and foreign exchange income.
During the period of review, the rainfall experienced was out of sync with the normal rainfall pattern with
moisture not being available at the critical periods as needed for the maturity of the crop. This abnormal
pattern of rainfall was to the detriment of two successive pineapple crops. The fruits produced were
smaller and cores larger, being unfit for processing by the factory’s standards. The study reveals that
even though there was the production of a smaller crop, the fruits were substandard relative to processing
criteria. The reasons were that the rains were not enough during the vegetative state of the pineapple
growth, triggering early flowering, just after which the rains came and there was too much water available,
leading to vigorous stem growth and large core development which is disadvantageous when the fruit is
used for canning
