Analisis Dampak Perubahan Iklim Terhadap Produksi Tanaman Pangan Pada Lahan Kering Dan Rancang Bangun Sistem Informasinya

Abstract

<p>Changes in the frequency and severity of extreme climate events and in the variability of weather patterns will have significant consequences for stability of agricultural system. Research objectives were to a) analyze the Impact of Climate Change on Food Crops in Dryland b) develop a software prototype analysis of the impact of climate change on food production, especially upland rice and maize on dry land; c) create a simulation with multiple scenarios of the impact of climate change on dry land. The study was conducted in South Sulawesi, West Nusatenggara and East Nusatenggara.The activities were carried out by projecting precipitation using scenarios: a) SRESA2 (Scenarios of climate change by assuming economic growth is lower and population growth remains high so the rate of greenhouse gas emissions increased, b) SRESB1 (scenario of climate change by assuming mitigation efforts through expanding efficient use of energy and technology improvements so that the emission levels are lower) and making projections of production of upland rice and maize using Decission Support System for Agrotechnology Transfer (DSSAT) as resource information in the preparation of prototype software information Systems Climate Change Impacts on Crop Production (SIDaPi TaPa). The system was built based on the analysis simulation model projections of production output DSSAT. Based on SRES scenarios A2, the decline in rainfall increased until 2050 in several districts, in South Sulawesi, West Nusatenggara and East Nusatenggara.Treatment of adaptation through SRESB1 scenarios could be effective to anticipate a decrease in rainfall in some regions, either in 2025 or 2050. In general, the region experiencing a decrease in rainfall will also decrease in production of both upland rice and maize production. The decline in upland rice production by SRESA2 scenario until 2050 was between 20-25%, and by a scenario adaptation SRESB1 the decline in production could be minimized to only between 7 -10%.The decline in maize production in the plot until 2050 by SRESA2 was between 9-15%, using scenarios to reduce production SRESB1 was only 5-8%. SIDAPI TAPA is a software analysis of the impact of climate change on food production, especially upland rice and maize on dry land in South Sulawesi, West Nusatenggara and East Nusatenggara.</p>

Analisis dampak perubahan iklim terhadap produksi kedelai dan pilihan adaptasi strategisnya pada lahan tadah hujan di Kabupaten Garut

“…Selain itu adanya pengaruh perubahan iklim menjadi salah satu faktor yang sulit dikontrol dan berdampak terhadap perubahan produksi kedelai. Apriyana et al (2016) menuturkan bahwa perubahan iklim di kawasan Asia Tenggara dapat menurunkan produksi tanaman kedelai sebesar 12,4%. Menurut penelitian Agung (2016) di Maluku, kedelai merupakan komoditas yang paling sensitif terhadap perubahan iklim karena memiliki dampak penurunan produksi ketika kondisi El Nino sebesar 10,7% maupun La Nina sebesar 11,4%.…”

Impact of climate change on cayenne pepper availability in Sleman District, Yogyakarta with dynamic system modelling

“…Inversely proportional to climate change which will reduce production results. Climate change affects 11% of agricultural land in developing countries, reducing agricultural production [15] and reducing Gross Domestic Product (GDP) by up to 16% [16]. Therefore, it is necessary to make policies related to increasing land area [17] and yard land utilization to maximize cayenne pepper production in Sleman District.…”

Tren Curah Hujan Berbasis Data Sinoptik BMKG Dan Reanalisis Merra-2 Nasa Di Provinsi Sulawesi Tengah

“…Perubahan kondisi iklim sangat erat kaitannya dengan perubahan pola dan intensitas curah hujan yang akan berdampak pada perubahan musim (Fuentes-Franco et al, 2015;Mufti et al, 2017;Setiawan, 2012). Berdasarkan penelitian dan kajian yang dilakukan oleh para ahli sebelumnya, perubahan intensitas dan pola curah hujan akan mempengaruhi banyak sektor di antaranya sektor pertanian dan ekonomi sosial serta lingkungan (Apriana et al, 2016;Hidayati & Suryanto, 2015;Hosang et al, 2012;Sudarma & As-syakur, 2018). Oleh karena itu, perlu dilakukan studi dan kajian tentang perubahan iklim dalam konteks perubahan pola atau laju pertumbuhan tren curah hujan untuk mengetahui kondisi terkini yang terjadi pada suatu wilayah.…”
