Global warming which leads to climate change has potential affect to Indonesia agriculture activities and production. Analyzing rainfall pattern and distribution is important to investigate the impact of global climate change to local climate. This study using rainfall data from 1976-2010 from both lowland and upland area of Lampung Province. The results show that rainfall tends to decrease since the 1990s which related to the years with El Nino event. Monsoonal pattern-having rain and dry season-still excist in Lampung; however, since most rain fell below the average, it could not meet crops water need. Farmers conclude that dry seasons were longer and seasonal pattern has been changed. Global climate change might affect Lampung rainfall distribution through changes on sea surface temperature which could intensify the El Nino effect. Therefore, watching the El Nino phenomena and how global warming affects it, is important in predicting local climate especially the rainfall distribution in order to prevent significant loss in agriculture productivities. ABSTRAKPemanasan global yang menyebabkan perubahan iklim memiliki potensi untuk mempengaruhi kegiatan dan produksi pertanian Indonesia. Kajian pola curah hujan dan distribusi sangat penting untuk mengetahui dampak perubahan iklim global terhadap iklim setempat. Penelitian ini menggunakan data curah hujan dari 1976-2010 dari kedua dataran rendah dan dataran tinggi wilayah Provinsi Lampung. Hasil penelitian menunjukkan bahwa curah hujan cenderung menurun sejak tahun 1990-an yang berhubungan dengan El Nino. Pola hujan musiman, musim hujan dan musing kering masih terjadi di Lampung; Namun, karena sebagian besar hujan jatuh di bawah rata-rata menyebabkan tidak bisa memenuhi kebutuhan air untuk pertanian. Petani menyimpulkan bahwa musim kemarau lebih panjang dan pola musiman telah berubah. Perubahan iklim global dapat mempengaruhi distribusi curah hujan Lampung melalui perubahan suhu permukaan laut yang dapat meningkatkan efek El Nino. Oleh karena itu, memperhatikan fenomena El Nino dan bagaimana pemanasan global mempengaruhi itu, penting dalam memprediksi iklim setempat terutama distribusi curah hujan untuk mencegah kerugian yang signifikan dalam produktivitas pertanian.Kata kunci: pemanasan global, perubahan iklim, distribusi curah hujan, El Nino
