Outline of Final Research Achievements

From obtained results of these experimentation, afforestation for carbon mitigation using hardpan-blasting method was confirmed to succeeded under complete rain-fed condition. And thus, this type of afforestation method can be applicable to whole area where Wiluna hardpan distributes, and then a huge CO2 mitigation potential of this afforestation method became promising.
Based on the observation data and simulation results, optimization of afforestation plot layout became available, and then 2 main points were revealed. Horizontally long rectangular shape and grid tree planting pattern had advantage on surface runoff-water collection. Since present results were intermediate, further studies on optimization of afforestation plot layout should be necessary.
