Climate assumptions 'optimistic at best'
April 9, 2008 09:29 AM - , SciDevNet
The UN Intergovernmental Panel on Climate Change (IPCC) has seriously underestimated the technological advances needed to stem carbon dioxide emissions, say Roger Pielke Jr, Tom Wigley and Christopher Green in Nature. They describe the IPCC's assumption that the majority of future emission reductions will occur spontaneously, in the absence of climate policies, as "optimistic at best and unachievable at worst".
Involve indigenous people in climate policy, says report
April 5, 2008 11:21 AM - , SciDevNet
The ingenuity of indigenous peoples is too often overlooked by policymakers making decisions related to climate change — even though they are among the most vulnerable to its impacts, according to a new report. The report from the International Union for Conservation of Nature (IUCN), released last month (March), points out that indigenous people usually occupy marginal and remote areas, such as small islands, coastal plains, mountain areas and drylands, where they are exposed to adverse environmental effects.
Antibiotic resistance and the developing world
March 28, 2008 11:51 PM - , SciDevNet
Developing countries, struggling under the burden of bacterial diseases such as tuberculosis, are more in need of antibiotics than ever. But issues such as proliferation of counterfeit drugs, poor prescribing practices and a lack of regulation or guidelines are fuelling the growth of resistance to these much needed medicines.
Restoring Tanzania's ecosystems
March 28, 2008 09:24 AM - , SciDevNet
Degraded land in western Tanzania is gradually being reclaimed — two decades after work began to rehabilitate the declining ecosystems. Once a thriving and diverse woodland environment, western Tanzania supported the livelihoods of local communities without difficulty.
Chinese biofuel 'could endanger biodiversity'
March 21, 2008 01:10 PM - , SciDevNet
[BEIJING] Using China's forests and 'idle land' to produce biofuels could pose a threat to biodiversity, warned experts at an international meeting. Spike Millington, chief technical advisor to the European Union-China Biodiversity Programme, raised the problem earlier this month (7 March) at the International Workshop on Biodiversity and Climate Change, held in Beijing, China.
Reforming the approach to 'demand-driven' research
March 21, 2008 12:28 PM - , SciDevNet
An evaluation of Dutch-funded research programmes in developing countries raises questions about the concept of local "ownership". Anyone interested in learning more about the possibilities and limitations of demand-driven research — in which research programmes are determined by those who will benefit from their results — should look at the recent experience of Dutch organisations that fund research in developing countries.
Tropical forest changes 'explained by multiple factors'
March 20, 2008 10:43 AM - , SciDevNet
Changes in the growth and species composition of tropical forests cannot be fully explained by global environmental changes, say researchers. Recent studies in the Amazon rainforest have suggested that changes such as the increase in atmospheric carbon dioxide (see Carbon emissions 'may alter forest growth patterns') and other factors such as nutrient deposition, temperature, drought frequency and irradiance are increasing the productivity and biomass of forests.
Aid needed to help China make carbon cuts
March 18, 2008 09:28 AM - , SciDevNet
nternational carbon funds should be aggressively directed towards helping China avoid the use of carbon-rich technologies, say Ning Zeng and colleagues in this Science article. Action is needed despite significant gains in energy efficiency, they note, because based on current economic growth rates and levels of carbon intensity (emissions per unit of gross domestic product) China's emissions by 2030 will equal today's entire global output.
China/EU alliance 'could be key to low-carbon energy'
March 13, 2008 09:31 AM - , SciDevNet
[BEIJING] China and the European Union (EU) can significantly advance low-carbon technologies if they cooperate closely on technological development and market access, according to a new report. 'Interdependencies on Energy and Climate Security for China and Europe', outlines common challenges faced by the China and the EU in dealing with the impact of climate change on energy security — despite differences in their economic development.
Conservation areas 'neglected' under current efforts
March 12, 2008 10:16 PM - , SciDevNet
The most important areas for biodiversity conservation are neglected under current protection efforts, researchers say. Scientists from the US-based University of California San Diego (UCSD) investigated whether current methods of locating conservation reserves are adequate to deal with future environmental changes.
