**Abstract**

Climate change has negative effects on food security, water security, and energy security due to change in extreme events such as floods, droughts, and heat waves, and reduces agricultural productivity. Global demand for food is projected to double by 2050. The rapidly growing population and the increase in demand for food, feed, and fuel will require sustainable agronomic practices to increase crop productivity. To meet the challenge, many advanced agronomic practices have been developed. For example: (1) selection of suitable crops and their varieties that are resistant to biotic stresses, (2) selection of suitable crops and their varieties that are resistant to abiotic stresses (3) selection of suitable cropping system, sustainable intensification. Sustainable agronomic practices are important to improve food security in changing climates. SDG-2 focuses explicitly on food by seeking to "end hunger, achieve food security and promote sustainable agriculture". SDG-1 focuses on poverty reduction, where agriculture have a key role to play. SDG-13 specifically calls for "urgent actions to combat climate change and its impacts." About 45 of the 169 targets are related to SDG-13, which highlights the need to tackle climate change and avert its impacts, particularly on food security, water, energy, and economic development.
