Changing Agriculture Scenario in Son-Karamnasa Interfluve in Bihar, India

There are various agricultural and environmental issues arising due to the climate change. The changes in the rainfall pattern and temperature leads to changes in the water resources, productivity and changing scenario in the agriculture. These changes also directly and indirectly influence the human society specially the poor people, for their livelihood as well as the economy of the nation, ultimately disrupt the sustainability. The concept of sustainability and development has close relationship with the climate change. United Nations Sustainable Development Goal (SDGs)13 aims isto “take urgent action to combat climate change and its impact”, while acknowledging that the United Nations Framework Convention on Climate Change is the primary international, intergovernmental forum for negotiating the global response to climate change.SDGs2 is to end hunger, achieve food security and improve nutrition and promote sustainable agriculture. Eradicating poverty and hunger are integrally linked to boosting food production, agricultural productivity and rural incomes. The aim of the study is to discuss the impact of climate change on decreasing the agriculture production in Son-Karamnasa interfluve in Bihar, covering four district such as Bhojpur, Buxar, Rohtas and Bhabhua, which is a part of Middle Ganga plain region. The study is purely based on the secondary data and field visits in the study area. The analysis reveals that there is highly probalility of increase in the frequency and intensity of drought in Bhabhua and Rohtas districts and flood in Buxar and Bhojpur district. The increase in the temperatures shorten crop cycles by reducing early flowering and shortening the grain-filling period, thereby reducing yield per unit area.
