Influence of an Ice Storm on Aboveground Biomass of Subtropical Evergreen Broadleaf Forest in Lechang, Nanling Mountains of Southern China

This study focuses on the influence of the 2008 ice storm in China and subsequent forest rehabilitation dynamics up until 2011. All seven plots studied exhibited significant damage, with the total number of damaged trees varying between 63 and 92%. In addition, most trees suffered stem bending in 2008 and the extent of damage varied with tree diameter at breast high (DBH). Relationships between loss of biomass as dead trees and stand characteristics were analyzed by multiple stepwise regression. The results showed that the decrease in biomass (Y) could be related to altitude (X1), slope (X2), and aboveground biomass (AGB) in 2008 (X5) according to the following formula: Y=−0.02456X1+0.2815X5−1.480X2+51.23. After 2 to 3 years, tree numbers had declined in all seven plots. The mean increase in AGB (4.9 t ha−1) for six of the plots was less than the biomass loss as dead trees (9.4 t ha−1) over the 3 year periods. This corresponds to a release of CO2 to the atmosphere for each plot. Therefore, the forests of Lechang in the Nanling Montains have probably acted as a carbon source to the atmosphere for a short period after the 2008 ice storm

Acceptance of New Land-Use Activities by Hmong and Khmu Ethnic Groups: A Case Study in Northern Lao People’s Democratic Republic

Reducing emissions from deforestation and forest degradation (REDD+) to address climate change has historically included little evaluation of how heterogeneous local communities respond to REDD+ interventions and new land-use activities. We assessed differences in the acceptance of new land-use activities as a function of livelihoods of the Hmong and Khmu ethnic groups in northern Lao People’s Democratic Republic, where REDD+ was implemented between 2011 and 2018. Our socioeconomic data, collected by a questionnaire-based survey and focal group discussions, showed that the Hmong more effectively incorporated support from REDD+ than the Khmu because the Hmong owned grazing land. Our findings highlight the importance of understanding the capabilities and characteristics of each ethnic group when implementing new land-use activities (i.e., designing and implementing alternative livelihoods) within a target area to ensure distributional equity in heterogeneous communities. Such a consideration should be included in land-use policy and also be a part of the social safeguards in the land-use sector
