Destocking as an emergency drought mitigation measure: lessons learned from the 2005 'Turkana emergency livestock off-take' intervention by Watson, D.J., Binsbergen, J. van

“…The TELO intervention had six specific objectives and the results are presented in relation to each in turn - to increase household cash income among pastoralists; to reduce pressure on water and pasture resources; to increase food security for vulnerable school children; to improve utilisation of assets with livestock owners gaining benefit from vulnerable livestock before the condition of the livestock deteriorates beyond the point of selling; to increase access to funds made available to livestock owners for future restocking; to use the money saved from school feeding program for school fees and/or other relevant projects for pastoralists' schools children. …”
