In Nepal more than 80% of the precipitation is received during the monsoon (June-September). Winter rains are more pronounced in the western hills. The prime sources of rain in Nepal is the monsoons blowing from the Bay of Bengal. These monsoons blowing from south-east direction into Nepal are forced to rise up along the slopes of mountains and hills. These contribute major proportion (60% to 90%) of the total annual rainfall received by various geographic regions of the country.

During winter, north-east monsoons blow in the north-east part of Nepal. Since these are dry and cold winds originating from land surface, these contribute very negligible proportion of rain. In this season, the main source of rain is the westerly cyclones approaching from the Mediterranean Sea.

The following bar diagram shows usual rainfall pattern in Nepal. But this year the pattern changed. During June / July there was absolutely no rainfall. Because of this most of the rice field become fallow. The major producing crop rice was planted only 50% area in Nepal. It surely indicates that there will be food problem in upcoming days.

I have concerned with one of the farmer about the present rainfall Patten. Same condition was happened ten years ago. And few years ago there was heavy rainfall occurred throughout the month in June. So unusual pattern of rainfall in not new but in present condition it will disturb national economy as well as ecosystem.

Devastating earthquake has made land weak. Due do this reason if heavy rainfall occur then there will be serious problem of landslides .so rainfall is necessary evil in present condition in Nepal. In recent ten days more than twenty people died due to landslides in hilly region of Nepal.

Another photo is taken from the experimental plot of rice field in Chitwan. The unusual pattern of rainfall cause flooding in my experimental plot. From yesterday heavy rainfall occurring in Chitwan. This type of rainfall is not suitable in any point of view.it is only destructive.so farmers are worried about their field. As climatic condition change then there will be emergence of new types of weed, insects and disease.

Due to climate change it is certain that, there will be food insecurity in near future. So we must think right now.it is sure that the yield of rice will decrease drastically. But we must bring it back. We must bring our rainfall pattern back to normal. We must aware about the negative impact of climate change.
