Coffee is an annual crop sensitive to climate variability. Most Indonesian coffee is cultivated on marginal lands that are vulnerable to environmental changes, including climate. Indonesia's climate variability is influenced by several factors, including the monsoon, local aspects, and global climate oscillations such as the El Nino-Southern Oscillation (ENSO) and the Indian Ocean Dipole (IOD). It is crucial to identify the impacts of climate variability on both the production and the economy to develop adaptative measures. This study aims to determine the effects of global climate variability, namely ENSO and IOD, on coffee production in several Indonesian production centers. It uses annual coffee production data in the five major production centers in Indonesia. The ENSO indicators used in this study were the Oceanic Nino Index (ONI) in the Nino 3.4 region and the IOD indicator in the Dipole Mode Index (DMI). The production anomaly analysis approach in neutral years and the extreme ENSO and IOD phases were applied in this study. The results showed that the effects of ENSO and IOD were different in each region. The highest decline in production occurred in the La-Nina year in almost all production centers. The decline in output in the La-Nina year ranged from 6 to 22%. Meanwhile, the IOD that had a decreasing effect on production was positive IOD with a decrease ranging from 1 to 15%.

Identification of climate change impacts on spatial and temporal rainfall pattern and length of growing period are very important for climate change adaptation strategy. Rainfed is an agro-ecosystem most sensitive to changes in rainfall patterns. Bone Regency is a center of agriculture in South Sulawesi and has considerable rainfed potentials. This study aims to identify changes of rainfall patterns and length of growing period (LGP) for paddy and upland rice in Bone Regency. Data of three rain stations with a 55-year period were used and Oldeman methods was applied to determine rainfall pattern and LGP. Data was separated in two period, period 1 (1961-1990) and period II (1991-2016). The pattern of changes were identified by comparing rainfall patterns in LGP I and II. This analysis was grouped by wet year, normal year and dry year with criteria developed by BMKG. The results of the analysis showed that the rainfall pattern and LGP had changed of which pattern of change varies between regions. The LGP of paddy in Macope were three months shorter in all years, while for upland rice were two months shorter in wet year, and 1 month in normal year. In Katumpi, the LGP of paddy fields were 2 months shorter comparing to the wet year and 1 month shorter in normal and dry year for upland rice. LGP for paddy in Cellu was lengthened 1 month in wet year and shortened 2 months in dry year for upland rice.

Climate change has significant negative impact on agriculture in tropical region. Inrecent years, research on climate change has focused mainly on food crops while horticultural crops have received little attention. This paper is an overview of Indonesian future climate projection for precipitation, temperature and extreme climate, climate change impact and adaptation strategies on vegetable and fruit crops and future challenge for horticultural development under climate change. The climate change will decrease crop productivity and quality, increase the incidence of new pest and disease, and the outbreaks on vegetable and fruit crops. Further climate change will disrupt water availability, alter climate-crop suitability and cause crop failure due to extreme climate. Several adaptation measures have been developed in farming system, among other adjustment of planting time, using resistant varieties to environmental strees, adopting irrigation technology for efficient water use, using green house and increasing farmers and extention service capacity through climate field school. For future research it is necessary to assess climate projections with several scenarios and Global Circular Models (GCMs) and their impact on future vegetable and fruits crops by developing crop modeling which should be given a priority of in agriculture. This information crucially needed for adaptation strategy and a long term agricultural planning in the future.Keywords: Vegetable, fruit, climate change, global circular model, adaptation AbstrakPerubahan iklim berdampak negatif terhadap pertanian di daerah tropis. Selama ini penelitian dampak perubahan iklim terhadap pertanian lebih banyak dilakukan pada tanaman pangan, sementara pada tanaman hortikultura, khususnya sayuran dan buah-buahan masih terbatas. Tulisan ini merupakan tinjauan tentang proyeksi dampak perubahan iklim di Indonesia yang meliputi curah hujan, suhu udara, dan iklim ekstrim terhadap produksi tanaman buah dan sayuran, di samping berbagai upaya adaptasi yang telah dilakukan dan tantangan pembangunan hortikultura ke depan. Perubahan iklim pada tanaman sayuran dan buah-buahan terbukti menurunkan kuantitas dan kualitas produksi, munculnya hama penyakit baru, meningkatnya serangan hama dan penyakit, gagal panen, penurunan kapasitas air irigasi, perubahan kesesuian lahan dan tanaman. Beberapa langkah adaptasi yang sudah dilakukan yaitu penyesuaian sistem usaha tani yang meliputi penggunaan varietas toleran cekaman lingkungan, penyesuian waktu tanam, penggunaan teknik irigasi hemat air, pengembangan teknologi pencarian sumber daya air baru, penggunaan rumah kasa/rumah plastik, peningkatan kemampuan petani dan penyuluh dalam memahami perubahan iklim melalui sekolah lapang. Ke depan masih perlu dilakukan kajian proyeksi iklim dengan berbagai skenario dan berbagai Global circular model (GCM) serta kajian dampak perubahan iklim terhadap tanaman sayur dan buah unggulan melalui pengembangan pemodelan sistem usaha tani. Informasi proyeksi dampak perubahan iklim diperlukan sebagai upaya adaptasi dan perencanaan pembangunan pertanian yang dikaitkan dengan perubahan iklim.Kata kunci: Buah-buahan, sayuran, perubahan iklim, global circular model, adaptasi
