Mapping agro-climatic zone for coffee crop in the Srepok River Basin

The objective of the present study was to map the agro-climatic zone for Robusta coffee crop in the Srepok River Basin. In this study, the trends of temperature and precipitation were identified using by the Mann - Kendall non-parametric test, the water deficit was calculated based on the CROPWAT model, and the agro-climatic zones for Robusta coffee crop were mapped using geographic information system (GIS). Results showed that the average annual temperature and the average annual rainfall had increasing trends. In addition, five agro-climatic zones were identified in the study area, including very appropriate, appropriate, neutral, restricted and inappropriate. Most of the territory was classified as Moderately Suitable for Robusta coffee. Suitable areas for the coffee cultivation were found in the east of the basin. Agro-climatic zoning will help managers and farmers improve crop yields effectively, avoid climate risks and maximize local advantages.
