Abstract

Establishment of techniques for carbon dioxide (CO2) fixation through afforestation have been previously described. Land used for large scale afforestation for carbon sequestration should not compete with agricultural and high productivity areas. Recently, agroforestry has been suggested as a countermeasure for problems caused by salinity or waterlogging. The aim of our research is to determine the optimum· method of afforestation for land rehabilitation and the best mix between crops and planting in semi-arid landscapes. Our research area at Nielsen Farm in Western Australia has areas containing both live and dead trees. In this study, we airried to understand the causes of tree death on this farm. Salinity problems were identified from the results of chemical analysis of soil and plant. However,there were also large seasonal fluctuations in groundwater levels. It was shown that at Nielsen farm, salinity and waterlogging problems occur simultaneously.
