building of small sand-mining enterprises. The results persuaded the Fiji Minister of Lands and Mineral Resources to agree to phase out extraction of river sand and gravel in favour of using crushed rock from quarries. In Cameroon, we supported the first monitoring system for sand and gravel production with the help of small-scale sand miners.
