Abstract

The negative Impact of climate change and food security are crucial issues for Indonesia with a large population. Agricultural sector as a contributor about 5-7 percent to CO 2 emissions, is a victim of climate change as this sector is very sensitive to the change of climate such as rise of temperature, drought, El Nino and La Nina and rise sea level. The decline in production due to climate change and extreme climate is very risky for Indonesia's food security. Various studies and studies have been conducted to evaluate the impact of climate change. However, since 2009, voluntary commitment of Indonesian Government to reduce 26 percent of CO 2 emissions set up the strong effort in many sectors to adapt with climate change. In agriculture, improving soil quality is key in maintaining food production. Soil conservation using vegetative or engineering technique is one of the most important technology. Nutrient management by applying balance fertilization, the use of organic material and ameliorant such as biochar, zeolite and other natural mineral are beneficial for plant production. All these ameliorants will be very useful in maintain soil organic matter (SOM) and soil carbon which very important in increasing water holding capacity. Water harvesting is one option to capture high precipitation and important to irrigate agricultural area. Besides, the use of cropping calendars, high yielding varieties which adapt to biophysical stress will be very useful. Other effort is also needed to control the peat fire, peat drainage and deforestation.
气候变化对印尼粮食安全的负面影响正在减少
气候变化的负面影响和粮食安全是印尼人口众多的关键问题。农业部门约占二氧化碳排放量的5- 7%,是气候变化的受害者,因为该部门对气温上升、干旱、厄尔尼诺和拉尼娜现象以及海平面上升等气候变化非常敏感。气候变化和极端气候导致的产量下降对印尼的粮食安全构成极大威胁。已经进行了各种各样的研究来评估气候变化的影响。然而,自2009年以来,印尼政府自愿承诺减少26%的二氧化碳排放量,为许多行业适应气候变化做出了强有力的努力。在农业方面,改善土壤质量是维持粮食生产的关键。利用植物或工程技术保持土壤是其中最重要的技术之一。平衡施肥、利用有机物质和改良剂如生物炭、沸石等天然矿物等养分管理有利于植物生产。这些改良剂在保持土壤有机质和土壤碳含量方面非常有用,这对提高土壤持水能力非常重要。集水是捕获高降水的一种选择,对灌溉农业地区很重要。此外,使用种植日历,适应生物物理胁迫的高产品种将非常有用。还需要采取其他措施来控制泥炭火灾、泥炭排水和森林砍伐。
