TL;DR: In this article, the authors analyzed the fuelwood consumption pattern for households along an altitudinal gradient in Garhwal Himalaya, Uttaranchal, India, and found that fuel wood consumption was influenced by climate and season of the year.
Abstract: The rural population of the Himalayas has been using firewood as the only source of energy for generations. Increasing population coupled with decreasing forest resources have led to strict environmental protection laws in the area. This paper analyses the fuelwood consumption pattern for households along an altitudinal gradient in Garhwal Himalaya, Uttaranchal. Firewood consumption was 2.80, 2.00, 1.42, 1.10 and 1.07 kg/capita/day , respectively, above 2000, 1500–2000, 1000–1500, 500–1000 and below 500 m altitude. The energy expenditure for fuelwood collection was 60.77, 62.57, 76.70, 87.23 and 85.14 MJ/capita/year , accordingly. Firewood consumption was influenced by climate and season of the year. On average, the fuelwood consumption was 2.0–3.0-fold higher in winter than summer (considering 265 days as winter and 100 days as summer). The present information on fuelwood consumption pattern by different altitude could form the basis for designing appropriate technologies for energy plantations in the region. The biomass consumption rate has also been discussed in environmental perspective in the Himalayan region.

TL;DR: In this article, the authors analyse firewood consumption along altitudinal gradient by households according to their socio-economic conditions in Garhwal Himalaya and find that consumption of fuelwood was 789, 664, 518, and 544 kg/cap-yr and energy consumption for fuelwood collection was 41, 53, 52, 80 × 103 kg/Cap-yr, respectively, above 2000, for 1500-2000, 1000-1500, 1000 -1500, and 500-1000m.

TL;DR: In this paper, the authors chart the understanding of landslide processes, prediction methods, and related land use issues, including land use, from timber harvesting and road building to urban and industrial development, and the effect of land use and climate change on landslides.
Abstract: Published by the American Geophysical Union as part of the Water Resources Monograph Series, Volume 18. Landslides are a constant in shaping our landscape. Whether by large episodic, or smaller chronic, mass movements, our mountains, hills, valleys, rivers, and streams bear evidence of change from landslides. Combined with anthropogenic factors, especially the development and settlement of unstable terrain, landslides (as natural processes) have become natural disasters. This book charts our understanding of landslide processes, prediction methods, and related land use issues. How and where do landslides initiate? What are the human and economic consequences? What hazard assessment and prediction methods are available, and how well do they work? How does land use, from timber harvesting and road building to urban and industrial development, affect landslide distribution in time and space? And what is the effect of land use and climate change on landslides? [Book Synopsis]

TL;DR: Future research on biophysical interactions should concentrate on exploiting the diversity that exists within and between species of trees, determining interactions between systems at different spatial and temporal scales, and improving understanding of belowground interactions.
Abstract: The rate and extent to which biophysical resources are captured and utilized by the components of an agroforestry system are determined by the nature and intensity of interactions between the components. The net effect of these interactions is often determined by the influence of the tree component on the other component(s) and/or on the overall system, and is expressed in terms of such quantifiable responses as soil fertility changes, microclimate modification, resource (water, nutrients, and light) availability and utilization, pest and disease incidence, and allelopathy. The paper reviews such manifestations of biophysical interactions in major simultaneous (e.g., hedgerow intercropping and trees on croplands) and sequential (e.g., planted tree fallows) agroforestry systems.

TL;DR: In this paper, a spatially explicit assessment of pan-tropical wood fuel supply and demand is presented to estimate where harvest exceeds regrowth and the resultant GHG emissions for 2009.
Abstract: Over half of all wood harvested worldwide is used as fuel, supplying ∼9% of global primary energy. By depleting stocks of woody biomass, unsustainable harvesting can contribute to forest degradation, deforestation and climate change. However, past efforts to quantify woodfuel sustainability failed to provide credible results. We present a spatially explicit assessment of pan-tropical woodfuel supply and demand, calculate the degree to which woodfuel demand exceeds regrowth, and estimate woodfuel-related greenhouse-gas emissions for the year 2009. We estimate 27–34% of woodfuel harvested was unsustainable, with large geographic variations. Our estimates are lower than estimates from carbon offset projects, which are probably overstating the climate benefits of improved stoves. Approximately 275 million people live in woodfuel depletion ‘hotspots’—concentrated in South Asia and East Africa—where most demand is unsustainable. Emissions from woodfuels are 1.0–1.2 Gt CO2e yr−1 (1.9–2.3% of global emissions). Successful deployment and utilization of 100 million improved stoves could reduce this by 11–17%. At US$11 per tCO2e, these reductions would be worth over US$1 billion yr−1 in avoided greenhouse-gas emissions if black carbon were integrated into carbon markets. By identifying potential areas of woodfuel-driven degradation or deforestation, we inform the ongoing discussion about REDD-based approaches to climate change mitigation. Over half of the wood harvested globally is used as fuel. Unsustainable harvesting can deplete woody biomass, contributing to forest degradation, deforestation and climate change. A spatially explicit assessment of pan-tropical woodfuel supply and demand is used to estimate where harvest exceeds regrowth and the resultant GHG emissions for 2009.
