    Land use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within 1979–2006 in Fuyang County (eastern China) and Fuyang Land Use Master Planning (FLUMP) (2006–2020) were selected for this pilot study.

    Due to the multiple impacts of landform effects, spatial heterogeneity and land use policies, farmland dynamics in mountainous areas are complicated. This study investigated farmland dynamics based on land use data from a typical mountainous area, Panxi, in China for 1990, 2000 and 2010, discussed the relationship between altitude, slope and farmland changes and presented an analysis of the driving forces of farmland change. Our findings are as follows: (1) from 1990 to 2010, the area of converted farmland was relatively small (313 km2), accounting for only 2.6% of the region’s farmland.

    The Cambodian government allowed 1,204,750 hectares as economic land concession (ELC) to 118 local and international companies. Global Witness reported that 2.6 million ha had been given in 272 ELCs, mainly for rubber plantations. Many concessionaires do not comply with their contracts, nor with existing land and forest laws. Government revenues from timber exports are extremely low. Deforestation, and removal of luxury timbers has increased dramatically. Land concessions rob local communities of their income from non-timber forest products.

    In order to develop the original long-term cutting age management standard of Sugi (Cryptomeria japonica) plantaions in Nagasaki prefecture, site index curves and taper tables of Sugi plantations were created. 1) Site idex curves were revised up after 40-50 years on stand age, and rate of height growth was not decreased remarkably. 2) On the average relative stem curve, the determination coefficient of polynomial expression was 0.9799. 3) The new taper tables could be applied to trees whose height from 15 to 31 m and DBH from 15 to 50 cm.

    The environment is deteriorating on a long-term basis in the Ejina River Basin in Inner Mongolia, China as a result of a water shortage. The shortage was caused by increased water use by industries and agriculture after 1992 along the upper part of the Ejina River. In 2002, the Chinese National Water Resource Agency instituted a water sharing plan which resulted in more water being released downstream to a region including the Kyoen Delta. The repartition will have an effect on vegetation increase in the Kyoen Delta area.
