An Acehnese worker prepares mangrove saplings, which will be planted later, in the village of Lamnga on the outskirts of Banda Aceh December 23, 2005. Construction spending in Aceh, devastated by last year's December 26 tsunami, will soon reach $2 billion a year, the United Nations Development Programme said. A 9.15 magnitude earthquake triggered the tsunami which left 170,000 people dead or missing in Aceh alone.
