Agroclimatic zoning for winemaking grape production in the State of Parana

Abstract

Paraná is the fourth largest grape producing state in Brazil and the cultivation of Vitis vinifera L. cultivars for winemaking is expanding is several regions of the state. The objective of this work was to characterize the potential of wine grape production based on the Géoviticulture Multicriteria Climatic Classification System for Paraná. A 30-year database constituted of 21 IAPAR (Agronomic Institute of Paraná) meteorological stations and 455 rainfall stations from Instituto das Águas do Paraná (Paraná State Water Institute) generated the following climatic indexes: dryness index (DI), heliothermal index (HI) and cool night index (CI) for the periods of October to March and April to September. According to the results, the viticultural climate of some regions in the state of Paraná belongs to the climatic groups where are found several traditional wine-producing regions in the world, showing potential for the expansion of winemaking in the state. Viticultural climate, associated with latitude in Paraná and with thermal conditions for vine growing cycle all over the year, make production displacement possible in the West, North and Northeastern regions and the production of the best quality grapes for winemaking in the fall and winter period, due to the most favorable cold night index and the lowest rainfall volume. In the coldest regions of the state (Center, South and East), it is only possible to have one production cycle, since the risk of frosts prevents the exploration of grapes in different periods.

Acurácia da Reanálise ERA-Interim do ECMWF e sua Aplicação na Estimativa da Deficiência Hídrica no Estado do Paraná, Brasil

“…2) com desvios variando entre -1,6 a -1,1ºC. Os maiores desvios ocorreram na macrorregião Noroeste, na qual se predomina também as mais elevadas T AIR do Estado do Paraná (Ricce et al 2014), evidenciando que o ERA-Interim subestima nas regiões onde ocorrem as mais altas T AIR . A acurácia da T AIR na primavera foi de MAPE = 3,04% e R 2 adj = 0,96 para todo Estado do Paraná (Fig.…”

“…O Paraná tem a quinta maior economia do Brasil e tem como um dos principais setores produtivos o agrícola (Rodrigues, Moretto, Guilhoto, 2015), produzindo feijão, café, algodão, trigo, mandioca e cana-de-açúcar (Aparecido et al 2016). Assim como no território brasileiro, não dispõe de uma rede de estações meteorológicas de superfície que atenda todas as necessidades agrícolas.…”

Agroclimatic risk zoning of mango (Mangifera indica) in the hydrographic basin of Paran River III, Brazil

“…The agroclimatic risk zoning consists of different levels of scales and exhibits the aptitude and risks from the specific areas for crops cultivation, through maps. The zoning considers the hydroclimatic requirements of each crops species (Ricce et al, 2018;Caldana et al, 2019).…”
