Climate Smart Agriculture (CSA) is a strategic approach that addresses the intricate connection between agriculture and the challenges posed by climate change on global food and nutritional security. CSA aims to incorporate these concerns and highlight their significance through sustainable farming practices that help mitigate the effects of climate change. Its goals include increasing agricultural productivity, fostering resilience to climate change and variability, and reducing greenhouse gas emissions for a more climate-smart world. It underpins sustainable intensification, adaptation, greenhouse gas (GHG) mitigation, and resilience. CSA contributes to food security through larger productivity, increased resilience, improved farmer and supply networks, and access to healthy diets. Yet, CSA faces constraint including policy and institutions, funding and technical gaps as well as social conditions. Solving these will require cooperation among government, policy- makers, scientists, farmers and others with an interest at stake. In the face of these challenges, CSA provides an encouraging avenue for securing sustainable food. It is imperative to combine these technologies with traditional practices and to have a sound policy support for successful up-scaling of CSA universally.
