Biofuel crops 'may amplify mosquito-borne disease'
January 23, 2014 01:29 PM - Wagdy Sawahel, SciDevNet
The expansion of the some biofuel crops may unwittingly increase the risk of mosquito-borne disease by altering the insects' life cycle, a study suggests. The so-called first-generation biofuel crops, most notably maize, are increasingly being replaced by second-generation biofuel crops, such as perennial grasses, which require less energy, water, fertilizers and pesticides to thrive.
Volume of electronic waste set to rise by a third
January 6, 2014 01:02 PM - Greenpeace India, SciDevNet
The amount of electronic waste produced globally is set to grow by a third between 2012 and 2017, according to a forecast made by experts at a global partnership created to tackle e-waste.
Forecasting storms using lightning!
January 3, 2014 09:43 AM - NASA via, SciDevNet
An alternative to costly radar-based weather services could soon be operational in developing nations, to help them detect severe storms more cheaply and quickly. The technology, which uses lightning detection to forecast when and where storms will strike, has already proven successful in demonstration projects in Brazil, Guinea and India. Next year, Earth Networks — one of the companies at the forefront of the technology — will conduct further trials in Haiti. As more developing nations increase their numbers of mobile phone masts, which are ideal locations for mounting the lightning sensors on, the proportion of countries using the technology looks set to increase, according to the US company.
Intelligent disaster relief
December 27, 2013 11:46 AM - Kieran Dodds/Panos, SciDevNet
The "fragmented" coordination between relief actors in the Philippines following Typhoon Haiyan last month underscores the need for artificial intelligence to streamline disaster response, says a team behind such an effort. The ORCHID project, a consortium of UK universities and private firms, aims to make this possible by combining human and artificial intelligence into an efficient complementary unit known as a Human Agent Collective (HAC).

Using Plankton to Control Malaria
December 17, 2013 09:02 AM - Joel Winston, SciDevNet
Improving the biodiversity of ponds and lakes in malaria-endemic regions could offer a powerful and sustainable way to control malaria. A common mosquito-controlling strategy is to apply biological insecticides, such as Bacillus thuringiensis israelensis (Bti) — a bacterium that produces toxins that target mosquito larvae. Because of this precise impact, Bti treatment preserves more biodiversity than chemicals such as DDT, which are lethal to most species.
UN shows how mobile-phone data can map human need
December 9, 2013 01:00 PM - Jan Piotrowski, SciDevNet
Tracking people’s movements after the Haiti earthquake, mapping malaria spread in Kenya, evaluating Mexico’s government policies on flu outbreak, improving national census surveys in Latin America and Africa... These are just a few examples of how mobile-phone data has been used in development, as highlighted by a recent UN report.
Developing technology for the developing world: Earthquake detection via smartphone
December 2, 2013 01:01 PM - Fred Furtado, SciDevNet
Countries that do not have or cannot afford earthquake detection systems may soon have an alternative thanks to a new technology being developed in the United States and discussed last week at the 6th World Science Forum (WSF), in Rio de Janeiro, Brazil.
Quick tsunami sensors tested in Mediterranean
November 20, 2013 08:58 AM - Giovanni Sabato, SciDevNet
A new alert system could improve tsunami warnings in the Mediterranean, but most countries bordering the sea still lack evacuation plans, scientists have said ahead of a meeting of 20 countries in Italy this week (19-21 November). The tenth session of the Intergovernmental Coordination Group for the North-Eastern Atlantic, Mediterranean and connected seas, Tsunami Warning and Mitigation System (NEAMTWS) will discuss establishing new national tsunami warning centres. It will also work towards organising the next tsunami exercise, a simulation of tsunami alerts following several different kinds of earthquakes, to evaluate the communication and response mechanisms throughout the NEATWS network.
Ocean acidification set to spiral out of control
November 15, 2013 06:57 AM - Jan Piotrowski, SciDevNet
The continued release of greenhouse gases into the air is set to bring about huge changes to land ecosystems as they are forced to adapt to rising temperatures. But the marine world — which is just as integral to human existence yet receives little attention during climate negotiations — will endure a similarly tumultuous time as emissions rise, scientists say. "Changing oceans will cause massive destruction of coral reefs, which, with their rich biodiversity, are the jungles of the sea," says Luis Valdes, the head of ocean science at UNESCO's Intergovernmental Oceanographic Commission (IOC-UNESCO), and co-author of a forthcoming report into ocean acidification.
