The methane uptake capacity of soil garden - Phuong Linh Ngo4. CONCULUSION The installation of rainfall exclusion roofs in the native garden led to a significant decrease of soil moisture at the surface and the top layers of the soil profile (top 15 cm). The decrease in soil moisture resulted in a corresponding increase in CH4 uptake in the soil which is comparable to other temperate eucalypt forest stu...

Precipitation scenarios in Ho Chi Minh city in the context of climate change - Nguyen Ky Phung4. CONCLUSIONS Based on the CSIRO-MK-3-6-0 model, by SimCLIM software, this research established precipitation scenarios in HCMC to 2100. By over the time and under the RCPs (RCP2.6 - RCP8.5), the average annual precipitation in HCMC would increase: 13.4 - 24 % by 2100 as compared to that in the period of 1986-2005 (1812 mm).
