Francisco M. Padilla and colleagues explored land-use changes and associated carbon sequestration that occurred through the 20th century in a rural area of southeast Spain. They observed that forest systems replaced dry land farming and pastures from the middle of the century onwards because of agricultural abandonment and afforestation programs. The area, which acts as a carbon sink, saw an increase in carbon stocks following the conversion of farmland to woodland. The authors carried out a land-use classification, determined carbon sequestration rates for the different types of land-use classes, and finally integrated total carbon stock of the different land-use units based on carbon sequestration rates. The area studied in Spain covered

The Progress and Challenges for the Implementa-tion of REDD+ in Tanzania
A number of challenges need to be overcome if REDD+ is to be successfully implemented in Tanzania, although the country has made a large effort to prepare for REDD+ and will be embarking on pilot projects in 2010 driven by donor funding.

Elevated Amazon Forest Tree Mortality Associated with Convective Storm Processes
A better understanding of forest disturbances linked to convective storm processes is needed given the increase in heavy precipitation cycles in the Amazon forest due to anthropogenic climate change. If a warming climate increases storm intensity and frequency, forest mortality may increase as well, resulting in greater carbon release into the atmosphere and further warming of the climate system. Negrón-Juárez et al. (2010) investigated forest disturbance produced by the storm to prove that a single squall line across the Amazon in January of 2005 caused widespread tree mortality, which may have caused the higher tree mortality that year. It is projected that it killed 0.3–0.5 million trees that year, equivalent to 30% of the annual deforestation. The results demonstrate the vulnerability of the trees in the Amazon to wind-driven mortality. –Abby Cheitlin
