Preventing the introduction of IAS through robust biosecurity and implementing early detection and rapid response mechanisms are crucial for effective management.

Invasive alien species often outcompete native species for resources, prey on native species, and alter habitat structure, leading to significant ecological disruption.

Climate change can alter environmental conditions, making it easier for invasive species to survive and reproduce, while simultaneously stressing native species and making them more vulnerable to invasion.

Invasive alien species are non-native organisms that establish themselves in a new environment and cause ecological or economic harm.

Biodiversity hotspots are characterized by a high number of endemic species and a significant level of threat from human activities.

The storage aspect of CCUS involves injecting captured CO2 into deep geological formations, such as depleted oil and gas reservoirs or saline aquifers, for long-term containment.

While captured CO2 can be used in fuels, building materials, and chemicals, directly applying it to enhance agricultural yields through atmospheric application is not a primary utilization pathway for captured CO2.

Direct Air Capture (DAC) refers to technologies that remove carbon dioxide directly from the surrounding air, rather than from a point source of emission.

Traditional CCUS systems typically capture CO2 from concentrated sources like emissions from power plants and heavy industrial processes.

CCUS is an acronym for Carbon Capture, Utilization, and Storage, a set of technologies aimed at reducing CO2 emissions.
