Abstract

The agricultural sector, particularly the rice farming system (SUT) is very vulnerable to climate variability and change. SUT that rely heavily on water will be easily affected by climate variability and change when the water supply deficit of needs that should be. SUT is still dominant in the food supply in Indonesia, so the shock of farming due to extreme climate events will have a major impact on food security. Many findings indicate that the frequency and intensity of extreme climate events will increase as a result of global warming. Extreme climate events dominant occur in center of rice production in West Java like Indramayu is drought. Approximately 80°/o of the causes of the rice harvest failed in the district of Indramayu is the incidence of droughts. Farmers as the main actors receive large impacts due to drought is expected to be increasingly difficult to develop the farm. It is therefore necessary to have protection program for farmers from the impact of climate events such climate extrim. One option is starting a lot of feasibility is Climate Index Insurance. This study aimed to assess thefeasibility of the implementation of the climate index insurance system in Indramayu. Analysis step is performedinclude (i) preparation of endemic drought maps are required as the basis in determining the priority areas ofclimate risk management and (ii) the determination of climate index value (threshold value) to be used as an index into the determination of the value of insurance claims. This study found that climate indices that can be used for the three villages at high risk of drought is high rainfall during the dry season. Index value for the three villages is 168 mm, 248 mm and 472 mm for Cikedung, lelea and Terisi. Potential applications of Climate Index Insurance for rice SUT in Indramayu is high because about 90°/o of the people are rice farmers. Besides benefit of rice farming is also quite large with B/C from 1.4 to 1.8 during the wet season and 1.2 to 1.7 on the dry season, so the expected ability to pay insurance premiums high enough.Keywords: Climate Index Insurance, drought, rice farming system.

Abstract

This research was aimed to investigate distribution of vulnerable region of dengue fever disease based on climate condition and population density in Indonesia. Climate condition, population density and vulnerability of district level were defined in the form of ordinal variable. The Koppen classification was used to proxy the climate condition. The population density was used to categorize the district level into small, medium and big cities. Regional vulnerability level was developed by using the values of IR and the 3-year consecutive incidence. The result of analysis using the frequency of incidence clarified that the population density and climate pattern influences the vulnerable level of the district. The big cities whose climate type are of Am (annual rainfall more than 1000 mm) and dry season is not extreme are the riskiest vulnerable region. On the contrary, the small cities whose dry season is not clear have high probability to be the safest region.

Abstract

The characteristics of swampland areas are different from agricultural land of Java, mainly in water availability. In swampland ecosystems there are unique environmental conditions. To assess risks of climate, mainly in climate change, we must assess about capacity and adaptation strategy. From treasure of related institution and interview with farmers,its had been known about climate impact on farming systems application, rainfall pattern and water availability. This paper aims to assess risks of climate on farming systems, application of adaptation strategy to reduce risks of climate and probability to provide of planting pattern alternative in the future in swampland areas (tidal marsh) in Delta Telang I, Delta Telang II and Delta Air Saleh, Banyuasin, South Sumatera.

Abstract

There are significantly decreasing of rainfall in wet season and dry season, and changed in onset of early season, that all of them can make crouded in plan of planting date, field actifity especially for food crops africulture. In the other side, climate is one of condition that has been ready and can not change, where probability of climate change will be reality that should be happened every time. Increasing frequency of climate extrem will give high impact in agriculture, especialy in rice-based farming system. This paper describes the climate risk based on statistical approaches. The climate risk is focused on flood and drought event. The analysis used was a chance occurrence based on time series data of rainfall and flood/droughts (affected and puso) based on median value from time series data. The goal of this research are : (1) to know rainfall critical value that can be influence flood and drought event in some of central food crops i West Java, (2) to know probability of flood and drought event in some of central food crops in West Java. The result of this research show that critical value of the rainfall that can be influence flood and drought event is very variety. Average of for flood event for paddy field near coastal based on median approach is 140 mm/month with probability 0,6. For another location, 166 mm/month with probability 0,68. Average of critical value of the rainfall for drought event is 64 mm/month for paddy field near coastal with probability 0,73. For another location, critical rainfall value is 119 mm/month with probability 0,76. For spesific research or detail scale (district or sub distric) we can use rainfall critical value and probablity based on data in that specific location because the data is more representative local riil condition.
