Efek Perubahan Zona Agroklimat Klasifikasi Oldeman 1910-1941 sampai dengan 1985-2015 terhadap Pola Tanam Padi Sumatera Barat

ARTICLE REVIEW: The Influence Of Climate Change On Rice Production And Cultivation Patterns In Indonesia

“…Due to these adaptations or adjustments made by farmers, cropping patterns can remain constant or change to yield essential food crops to meet demands. The research findings by Saputra et al (2018) indicate a shift in climate types in five rice-producing districts in the province of West Sumatra across three different periods (1910-1941, 1977, and 1985-2015). The five locations observed are as follows: Lima Kaum shifted from E1 (Very dry) to D1 (Dry) and became E3 (Very dry), Rao changed from D2 (Dry) to D1 and became C1 (Fairly wet), Luhak Situjuh transitioned from B1 (Wet) to E1 (Very dry), Gunung Talang shifted from A1 (Very wet) to B1 (Wet), and Sijunjung shifted from C1 (Fairly wet) to B1 and became D1 (Dry).…”

“…El Niño has a significant impact on reducing rice production and productivity in Indonesia. Saputra et al (2018) add that changes in the agro-climatic zone of the Oldeman classification have been observed to affect the alteration of rice planting patterns and decreased productivity in rain-fed paddy fields in several riceproducing regions of West Sumatra, including Luak Situjuh, Panti, and Lima Kaum.…”

Penentuan Zona Agroklimatologi Untuk Kesesuaian Lahan Pertanaman Padi Di Kabupaten Tojo Una-Una

“…Salah satu klasifikasi iklim yang digunakan tanaman pangan adalah klasifikasi agroklimat Oldeman. Metode ini menggolongkan tipe-tipe iklim di Indonesia berdasarkan pada kriteria bulan-bulan basah dan bulan bulan kering secara berturut-turut (van Wesenbeeck et al, 2016;Saputra et al, 2018).…”

“…Perubahan zona iklim menurut klasifikasi Oldeman juga mengubah pola tanam padi sawah tadah hujan menjadi palawija. Jika sawah tersebut tidak mendapat tambahan air irigasi maka petani cenderung menanam padi gogo atau tanaman jagung, singkong, ubi jalar, atau kacang-kacangan yang tidak membutuhkan banyak air dan minim risiko kegagalan (Saputra, 2018).…”
