Farmers in Indonesia used to be thinking about cropping plants based on two seasons, they were hot and rainy seasons. This calendar system was based on the natural process of raining and hot weather. But, today’s farmers would not crop their plant based on the weather as the climate change presents. The food productions particularly from carbohydrate-producing plants, fruits and vegetables are affected by the changing of climate change. Is this the only impact resulting from the greenhouse effect?

However, the criteria of non-habitable planets are not merely based on the temperature, CO2, rainfall or humidity or any others, but the domino effects which are the source of nutritional food. The climate change could affect the food security into low-level of nutrition, suggested by Myers et al., it is because the quantity of agricultural production depends on the availability of biophysical resources which are
- Soil quality with micro and micro ecosystem
- Water availability
- Quality of sunlight
- Carbon dioxide
- Suitable condition and temperature
- The presence of pollinator
Climate change affects the production of food
The global temperature has been elevating in the last ten to fifteen years. It has been estimated the elevation of temperature around 1 centigrade for every 10-15 years. By calculating it linearly, we can predict that in the next century the temperature will be 7-10 centigrade hotter than today. This calculation is not only based on the mere multiplying, but the consideration based on our activity in generating the greenhouse gases.
The scientists from Harvard University suggested that either oceans and land has been affected by CO2 and high temperature, so subsequently, followed by the acidification happened in the oceans floor, meaning the habitats of the fish are disturbed. Corals reef is the main source of food for marine life. The degradation in amount will influence the nutrition content of fish since corals are the primary producer of food in marine ecosystem. On the other words, the disturbance occurring in ocean alters the nutrition within fish.
In the meantime, the weather is also affected by the changing of temperature and the higher of temperature creates stress either for animals – such as livestock – and plants particularly for fruits and vegetables. Technically speaking, the animals will demand more water resources as the same as the plants. If the competition of consuming water is not balance, so neither animals or plant could grow optimally. In the causal conclusion, both impacts cause unstable price and productivity in food preservation and security, which economically means the price will be higher but the nutrient contents are low.
Primary resources of food will be affected by climatic change
Food sovereignty must be achieved and the way to address that is by preventing the Earth becoming warmer. The level of carbon dioxide airborne which can cause broken in the ozone layers on the atmosphere must be reduced. However, the increasing level of carbon dioxide will give positive effect as crops also demand the gas for fuel. Nevertheless, the future scenario when the alternating of climate provides agricultural issue on maize and wheat which are consumed by many people either in northern parts of America and Europe. On the contrary, the rice will be “okay” as it is less sensitive to be affected.
