From 2003-2006, 34 research projects were carried out at LDC-CelAgrid with the financial support from Swedish International Development Authority (Sida)/Swedish Agency for Research Cooperation (SAREC) through MEKARN for Research Cooperation for Livestock-based Sustainable Agriculture in the Lower Mekong Basin, Cambodian Agricultural Research Fund (CARF), International Foundation for Sciences and Centro International para Agricultura Tropical and articles were published in various local and international journals (see publications). However, 24 main topics with 40 experiments are going and need to be carried during 2007-2009. The topics of these experiments are listed below:
