Climate Change and Price Volatility: Can We Count on the ASEAN Plus Three Emergency Rice Reserve?
ADB, 2012On 12 July 2012, the Association of Southeast Asian Nations (ASEAN) Plus Three intergovernmental agreement establishing the ASEAN Plus Three Emergency Rice Reserve (APTERR) entered into force. In this paper, lead author Roehlano Briones, a senior research fellow at the Philippine Institute for Development Studies, assesses the effectiveness of APTERR as a mechanism for addressing food security in light of the rising challenges of climate change and price volatility. Using Riceflow, a model of the global rice economy, he studies the possible impacts of APTERR releases on the rice market by simu ...
Flood Risk Management in the People's Republic of China: Learning to Live with Flood Risk
ADB, 2012This publication presents a shift in the People’s Republic of China from flood control depending on structural measures to integrated flood management using both structural and non-structural measures. The core of the new concept of integrated flood management is flood risk management. Flood risk management is based on an analysis of flood hazard, exposure to flood hazard, and vulnerability of people and property to danger. It is recommended that people learn to live with flood risks, gaining and promoting a clear understanding of flood risks, quantifying and modifying the flood hazard, regula ...

Sustainable low-carbon city development in China
Cities contribute an estimated 70 percent of the world's energy-related greenhouse gases (GHG). Their locations, often in low-elevation coastal zones, and large populations make them particularly vulnerable to the impacts of climate change. But cities often take steps, even ahead of national governments, to reduce GHG emissions. So it is with China's cities, which are well placed to chart a low-carbon growth path to help reach China's national targets for reducing the energy and carbon intensity of its economy. China's cities will need to act on multiple fronts, in some cases scaling up elemen ...

Le Karakorum, glacier de l'Himalaya qui ne fond pas: In lemonde.fr
2012Les glaciers de l'Himalaya fondent lentement, mais une partie d'entre eux sont dans un état stable, voire regagnent légèrement du volume : c'est ce qui ressort de deux articles scientifiques parus dans les revues Science du 20 avril et Nature Geoscience du 15 avril.

Projections of air pollutant emissions and its impacts on regional air quality in China in 2020
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Xing J.; Wang S.X.; Chatani S.; et al. - Copernicus GmbH, 2011Anthropogenic emissions of air pollutants in China influence not only local and regional environments but also the global atmospheric environment; therefore, it is important to understand how China's air pollutant emissions will change and how they will affect regional air quality in the future. Emission scenarios in 2020 were projected using forecasts of energy consumption and emission control strategies based on emissions in 2005, and on recent development plans for key industries in China. We developed four emission scenarios: REF[0] (current control legislations and implementation status), ...

Analysis on the impact of aerosol optical depth on surface solar radiation in the Shanghai megacity, China
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Xu J.; Li C.; Shi H.; et al. - Copernicus GmbH, 2011This study investigated the decadal variation of the direct surface solar radiation (DiSR) and the diffuse surface solar radiation (DfSR) during 1961–2008 in the Shanghai megacity as well as their relationships to Aerosol Optical Depth (AOD) under clear-sky conditions. Three successive periods with unique features of long term variation of DiSR were identified for both clear-sky and all-sky conditions: a "dimming" period from the late 1960s to the mid 1980s, a "stabilization"/"slight brightening" period from the mid 1980s to the mid 1990s, and a "renewed dimming" period thereafter. During the ...

Distribution and air-sea exchange of mercury (Hg) in the Yellow Sea
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Ci Z.J.; Zhang X.S.; Wang Z.W.; et al. - Copernicus GmbH, 2011The Yellow Sea, surrounded by East China and the Korea Peninsula, is a potentially important receptor for anthropogenic mercury (Hg) emissions from East Asia. However, there is little documentation about the distribution and cycle of Hg in this marine system. During the cruise covering the Yellow Sea in July 2010, gaseous elemental mercury (GEM or Hg(0)) in the atmosphere, total Hg (THg), reactive Hg (RHg) and dissolved gaseous mercury (DGM, largely Hg(0)) in the waters were measured aboard the R/V Kexue III. The mean (±SD) concentration of GEM over the entire cruise was 2.61 ± 0.50 ng m−3 (ra ...

Origin and radiative forcing of black carbon transported to the Himalayas and Tibetan Plateau
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 3. Kopacz M.; Mauzerall D.L.; Wang J.; et al. - Copernicus GmbH, 2011The remote and high elevation regions of central Asia are influenced by black carbon (BC) emissions from a variety of locations. BC deposition contributes to melting of glaciers and questions exist, of both scientific and policy interest, as to the origin of the BC reaching the glaciers. We use the adjoint of the GEOS-Chem model to identify the location from which BC arriving at a variety of locations in the Himalayas and Tibetan Plateau originates. We then calculate its direct and snow-albedo radiative forcing. We analyze the seasonal variation in the origin of BC using an adjoint sensitivity ...

Climate: observations, projections and impacts
The Met.Office, 2011Understanding the potential impacts of climate change is essential for informing both adaptation strategies and actions to avoid dangerous levels of climate change.
But assessing the impacts is scientifically challenging and has, until now, been fragmented. To date, only a limited amount of information about past climate change and its future impacts has been available at national level, while approaches to the science itself have varied between countries.
In April 2011, we were asked by the United Kingdom's Secretary of State for Energy and Climate Change to begi ...
Terrain Effects on an Afternoon Heavy Rainfall Event, Observed over Northern Taiwan on 20 June 2000 during Monsoon Break
Journal of the Meteorological Society of Japan, Vol. 88. No 4. Chen Ching-Sen; Liu Che-Ling; Yen Ming-Cheng - Meteorological Society of Japan, 2010An afternoon heavy rainfall event in northern Taiwan, observed on June 20, 2000 during the monsoon break, is investigated using surface observation and Doppler radar data and a nonhydrostatic model with a horizontal grid spacing of 1.33 km. Heavy rainfall was brought majorly by two precipitation systems, namely A and B. System A was initiated and developed in Taipei Basin, associated with a local wind convergence line. System B was formed on the western slopes south of Taipei Basin, extended northward of the Taipei Basin, and lasted for 4 h. The formation and maintenance mechanisms of the two ...
