Physico-chemical properties of soil of two dominant forest types in Western Himalaya, viz. oak (Quercus leucotrichophora) and pine (Pinus roxburghii) across three soil depths, and winter and rainy seasons were analysed. In general, all the soil parameters, viz. soil moisture, water-holding capacity, organic carbon and total nitrogen decreased significantly with increasing soil depth in both the forests. However, pH did not show any trend with soil depth. All the soil physicochemical parameters were found significantly higher for oak forests compared to pine forests.

Tropical agroforestry has an enormous potential to sequester carbon while simultaneously producing agricultural yields and tree products. The amount of soil organic carbon (SOC) sequestered is however influenced by the type of the agroforestry system established, the soil and climatic conditions and management. In this regional scale study, we utilized a chronosequence approach to investigate how SOC stocks changed when the original forests are converted to agriculture, and then subsequently to four different agroforestry systems (AFSs): homegarden, coffee, coconut and mango.

This paper provides field experiment–based evidence on the potential additional forest carbon sequestration that cleaner and more fuel-efficient cookstoves might generate. The paper focuses on the Mirt (meaning “best”) cookstove, which is used to bake injera, the staple food in Ethiopia.

Forty years after the ocean floor was first mapped by hand, a team of Australian researchers has created the first digital map of the entire sea floor. Made by the University of Sydney's School of Geosciences and National ICT Australia (NICTA), the map can be used to plot the planet's underwater carbon sinks and understand how oceans respond to climate change.

The researchers combined Landsat and MODIS data in a land model to assess the impact of urbanization on US surface climate. For cities built within forests, daytime urban land surface temperature (LST) is much higher than that of vegetated lands. For example, in Washington DC and Atlanta, daytime mean temperature differences between impervious and vegetated lands reach 3.3 and 2.0 °C, respectively. Conversely, for cities built within arid lands, such as Phoenix, urban areas are 2.2 °C cooler than surrounding shrubs.

Plantation-associated drainage of Southeast Asian peatlands has accelerated in recent years. Draining exposes the upper peat layer to oxygen, leading to elevated decomposition rates and net soil carbon losses. Empirical studies indicate positive relationships between long-term water table (WT) depth and soil carbon loss rate in peatlands. These correlations potentially enable using WT depth as a proxy for soil carbon losses from peatland plantations. Here, we compile data from published research assessing WT depth and carbon balance in tropical plantations on peat.

Further degradation of Indonesia's forests could impact the national economy and the lives of millions, according to a new UN study titled "Forest Ecosystem Valuation Study: Indonesia".

Researchers are racing to determine whether forests will continue to act as a brake on climate change by soaking up more carbon.

There has been extensive debate about whether the sustainable use of forests (forest management aimed at producing a sustainable yield of timber or other products) results in superior climate outcomes to conservation (maintenance or enhancement of conservation values without commercial harvesting). Most of the relevant research has relied on consequential life-cycle assessment (LCA), with the results tending to show that sustainable use has lower net greenhouse-gas (GHG) emissions than conservation in the long term.

This compendium is released on the target year of the Millennium Development Goals (MDGs). While there has been remarkable progress on the MDGs, such as halving the
