when managing pasture lands, does it cause an increase in CO2 or does it decrease?
It depends on the specific management practices implemented on the pasture land. In general, well-managed pasture lands can help to sequester carbon dioxide from the atmosphere through the growth of plants and their root systems. This can help to mitigate the effects of climate change. However, poor management practices such as overgrazing or land conversion can release stored carbon and contribute to an increase in CO2 levels.
Overall, sustainable pasture management practices can potentially lead to a decrease in CO2 levels, while unsustainable practices may contribute to an increase. It is important for land managers to implement practices that promote soil health, plant growth, and carbon sequestration in order to reduce the impact of pasture lands on CO2 levels.
