Leucaena is widely recognized as the most sustainable, and valuable multipurpose tree legume in the tropics. For livestock, it is a productive and profitable source of protein for ruminant production. Its other multipurpose uses include:- land regeneration; carbon sequestration and methane reduction; biomass for paper pulp and electricity generation. Over the past three decades, scientists and farmers have greatly increased their knowledge of this plant, resulting in new plantings that have grown almost exponentially over time. As a consequence, there is demand for improved knowledge of the latest varieties, recommended management practices, and feeding systems. You are invited to attend an international conference on the tree legume leucaena (Leucaena leucocephala) and other species in the Leucaena genus to be held on the resort Island of Lombok in eastern Indonesia 29 October – 2 November 2018.
