Q

techniques used to manage RLD

A

-afforestation projects reduce wind erosion and prevents soil erosion as the tree roots bind the soil together

-fenya juu terraces (popular in tanzania) have been made by digging a drinage channel and throwing soil uphill to make a ridge to increase infiltration

-use of fuel efficient stoves e.g “jiko”
reduces demand for firewood therefore more trees left to prevent wind and water erosion

-nomadic farmers encouraged to reduce the number of livestock to reduce soil compaction

-movable fencing allows farmers to control grazing area, allowing soil to recover at different times of the year

Q

comment on the effectiveness of techniques used to manage RLD

A

AFFORESTATION
✅depending on tree type, seeds and pods are a good source of protein for livestock, add benefits
❌expensive! green wall project, expected cost is $8B
❌too expensive for most developing nations like the sahel, as focus is services for the ppl
NOT EFFECTIVE

FUEL EFFICENT STOVES LIKE JIKO
✅effective, uses half the amount of fuel than an open fire

REDUCING LIVESTOCK NUMBERS WITH NOMADIC FARMERS
❌they will resist, large livestock size=large status

FENYA JUU TERRACES
✅low technology approach
❌building g and maintaining is very labour intensive
