| Summary: | Climate change impacts on drylands pose more vexing risks to socio-ecological
systems, resulting in food security issues, biodiversity loss, and livelihood shifts in
Africa. This study critically reviewed relevant literature to evaluate the complexities
and feedback loops between the climate–drylands–food security (CDF) nexus,
which helps assess tactics to attain sustainable dryland ecosystem management
under the changing environment. Comprehensive CDF frameworks are explored
for dryland dynamics, ecosystem services, and food security (FS), and current high precision ecosystem observation networks are used to detect regional-level
climate variability and identify hotspots. In addition, this review also examines
challenges and uncertainties for CDF systems and effective agrarian innovations as
a way forward. To bridge the gap from science to policy making in the CDF nexus, it
is vital to enhance the impacts and feedbacks of ecohydrological processes on
agrarian production, ecosystem service tradeoffs and their effects on livelihoods,
and regional development and preservation by optimization of the ecological water
security pattern. This state-of-the-art assessment uses acquired information and
knowledge to conceptually evaluate the past, current, and future impacts and risks
and facilitates decision making through the delivery of long-term sustainability and
socio-ecological resilience. |
