Abstract

Worldwide, semiarid rainfed areas are among the most vulnerable to the effects of global warming on agriculture. Biochar, a carbon-rich byproduct of pyrolysis, improves soil health and reduces emissions of greenhouse gases; it is an environmentally friendly option. In this study, we look at how biochar may improve soil fertility, decrease nitrous oxide (N2O) and methane (CH4) emissions, and sequester carbon. Biochar is perfect for semiarid regions because of its porous nature, which helps to retain more water and lessen soil erosion. Research in India and sub-Saharan Africa has shown that biochar may reduce greenhouse gas emissions while increasing agricultural yields by 150%. However, problems including poor awareness and high manufacturing costs must be resolved to achieve broad acceptance. Regarding combating climate change, biochar is an essential weapon for sustainable agriculture.

Conclusion

Utilising biochar in semiarid rainfed agriculture presents a game-changing opportunity to enhance environmentally responsible practices while simultaneously lowering emissions of greenhouse gases. Carbon can be captured, emissions of nitrous oxide and methane can be reduced, soil fertility can be increased, and water retention can be improved. This makes it a powerful weapon in the battle against climate change. Biochar has been shown to potentially reduce the negative impacts of agricultural inputs on the environment while enhancing harvest yields, according to research conducted in India and sub-Saharan Africa. However, for it to be used by more people, issues like high production costs and a lack of understanding among farmers need to be resolved. By incorporating biochar into agricultural systems, it is possible to achieve sustainable food production, enhanced soil health, and long-term agrarian resilience in areas prone to environmental stress. Furthermore, this will help to reduce the effects of climate change.
