The 26 December 2004 earthquake and tsunami devastated the lives of millions. With considerable determination, local communities have joined national and international organizations and governments to bring relief and start the recovery work. FAO has been involved in assisting the affected countries in numerous ways so that agricultural activities may be resumed. While short-term assistance is indispensable, strategic planning for medium and long-term rehabilitation in collaboration with partners and governments is required for appropriate intervention.

Dyera polyphylla, which is locally known as jelutung, is a tree that produces latex. The latex is used for chewing gums, insulator, tube, and others. The wood is soft and bright colour, which can be used for pulp, plywood, pencil, wooden toy, and others. It naturally grows on peat swamp forests in Sumatra and Kalimantan (Indonesian part of Borneo). Along with fast deforestation, population of wild jelutung is decreasing. In the era of degraded peatland restoration, jelutung was promoted to be planted in reforestation and afforestation.

Agriculture is coming under more and more pressure to justify its use of the world's freshwater resources and to improve its productive and environmental performance. The allocations of raw water to agriculture (and the allocations within the agriculture sector) all need to be negotiated in a transparent way. This report reviews the large set of literature on the subject and makes the case for the adoption of a functional approach to water valuation as a basis for such negotiation.
