Exposure pattern of tobacco cultivation places due to climate change in Probolinggo district, East Java

Abstract

Probolinggo District is one of the centers of tobacco producer in Indonesia, paiton tobacco as local varieties included in dry season type of tobacco (Voor Oogst). Rainfall as well as dry season dynamics in 2015 and 2016 which had already been global, is affected tobacco cultivation and additional values to farmers in Probolinggo district. This research has purpose to identify the exposure patterns of tobacco cultivation places in Probolinggo district related to climate change. Based on daily rainfall data during 1990–2016 from 50 rain gauge stations, parameters of exposure due to climate change are processed by using de Boer method and mapped by using Thiessen polygon method. Determination of level of exposure places are done by scoring method and map overlay technique, then associated with landuse. The analysis results showed that exposure pattern with low level tend to be in the coastal areas and lowlands, stretching from West to East. The higher elevation is, the higher level of exposure places.
