The impacts of climate change on agricultural sustainability vary from country to country, region to region and time to time. The yield and productivity of agricultural crops in Malaysia are proven to have been heavily influenced by climatic variations. Malaysia is the 26th largest greenhouse gas emitter which causes the expected rise of temperature by 0.3oC to 4.5oC, and rise in sea level is expected to be about 95cm over the time span of one hundred years. The changes in the country’s rainfall fluctuate heavily from -30% to +30%. This change reduces crop yield and is prone to drought in many areas so that cultivation of some crops such as rubber, oil palm and cocoa becomes unfeasible. Current crop productivity is also affected by the climatic variations throughout the country as the actual farm yields of rice in Malaysia vary from 3-5 tons per hectare while the potential yield is 7.2 tons per hectare. The projection of climate change and its impacts on productivity and farmers’ profitability are thus considered very alarming.
