TL;DR: In this paper, a 3D point cloud was generated from aerial photographs using the Structure from Motion (SfM) approach to estimate aboveground biomass (AGB) in a tropical forest.

TL;DR: The observed patterns can be explained by environmental homogenization under logging, which is biased to particular species and larger diameter at breast height, and forest patrol has been effective in decreasing logging.

Object-Based Mapping of Aboveground Biomass in Tropical Forests Using LiDAR and Very-High-Spatial-Resolution Satellite Data
Yasumasa Hirata,Naoyuki Furuya,Hideki Saito,Chealy Pak,Chivin Leng,Heng Sokh,Vuthy Ma,Tsuyoshi Kajisa,Tetsuji Ota,Nobuya Mizoue +9 more
TL;DR: This study developed a method to support REDD-plus implementation by estimating tropical forest aboveground biomass (AGB) by combining airborne LiDAR with very-high-spatial-resolution satellite data and suggests that this approach can provide the forest carbon stock per unit area values required to supportREDD- plus.

Factors Affecting Forest Area Changes in Cambodia: An Econometric Approach
TL;DR: In this article, the authors analyzed some socioeconomic factors and clarified their relationship with deforestation in Cambodia for the period of 2002 to 2010, and found that population, gross agricultural production and large-scale plantation development have negative impacts on forest area changes.
Estimating aboveground carbon using airborne LiDAR in Cambodian tropical seasonal forests for REDD+ implementation
Tetsuji Ota,Tsuyoshi Kajisa,Nobuya Mizoue,Shigejiro Yoshida,Gen Takao,Yasumasa Hirata,Naoyuki Furuya,Takio Sano,Raul Ponce-Hernandez,Oumer S. Ahmed,Heng Sokh,Vuthy Ma,Eriko Ito,Jumpei Toriyama,Yukako Monda,Hideki Saito,Yoshiyuki Kiyono,Sophal Chann,Nang Ket +18 more
TL;DR: In this article, an empirical model was developed to estimate aboveground carbon density with variables derived from airborne Light Detection and Ranging (LiDAR) in tropical seasonal forests in Cambodia, and assessed the effects of LiDAR pulse density on the accurate estimation of aboveground CO 2.
