Summary
Climate change threatens global food security by reducing crop yields. This review highlights sorghum as a climate-resilient crop and explores strategies for its improvement to ensure future food and feed security.
Area of Science:
- Agricultural Science
- Climate Change Adaptation
- Plant Breeding
Background:
- Climate change, characterized by extreme weather events, significantly disrupts global agriculture and food production.
- Crop losses due to climate change exacerbate food insecurity, poverty, and threaten the livelihoods of smallholder farmers, especially in developing nations.
- There is a critical need for climate-resilient food crops that require fewer inputs and offer sustainable yields through enhanced stress tolerance.
Purpose of the Study:
- To review the sensitivity of sorghum to climate change-induced stress events.
- To explore available crop improvement strategies for sorghum.
- To promote the adoption of sorghum in climate-smart agriculture initiatives.
Main Methods:
- Literature review focusing on sorghum's response to climate change.
- Analysis of existing crop improvement techniques for sorghum.
- Synthesis of information on climate-resilient agriculture.
Main Results:
- Sorghum exhibits notable resilience to climate change vulnerabilities compared to other staple crops.
- Understanding sorghum's sensitivity to various stresses offers pathways for enhancing its yield and nutritional quality.
- The review identifies potential strategies for improving sorghum to meet future food and feed demands.
Conclusions:
- Sorghum is a vital climate-resilient crop crucial for addressing global food insecurity.
- Targeted crop improvement strategies can further enhance sorghum's role in climate-smart agriculture.
- Adapting and improving sorghum is essential for ensuring sustainable food and feed security in a changing climate.

01:16What is Climate?
19.7K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:57Adaptations that Reduce Water Loss
27.1K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

01:50Global Climate Change
27.7K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
