Bats can help protect rice farms against pests
April 14, 2014 02:28 PM - Yao-Hua Law, SciDevNet
[KUALA LUMPUR] Bats that prey on a major rice pest in Thailand could save paddy harvests worth millions of dollars and help contribute to better food security, scientists say in a paper published in Biological Conservation recently (March).
IPCC warns over greater risk to food and water security
April 2, 2014 10:38 AM - F.Fiondella/IRI/CCAFS, SciDevNet
[NEW DELHI] The climate change-related risks from extreme events such as floods and heat waves will rise further with global warming, aggravating food and water insecurity, especially for some of the poorest communities, says the second instalment of the latest UN Intergovernmental Panel on Climate Change (IPCC) report.
Seaweed forests could help power tropical islands
April 1, 2014 06:45 AM - Jan Piotrowski, SciDevNet
Harvesting seaweed 'forests' and feeding them into large underwater digesters could one day meet the world's energy needs, with nine per cent of the ocean floor being enough to replace fossil fuels entirely, according to an ambitious idea. Even a more immediate and realistic use of seaweed — a major untapped resource — would greatly increase the self-sufficiency and sustainability of small island states, but limited investment is preventing the roll-out of relevant technologies, marine biofuel experts have said.
Climate-hit fisheries 'can still meet demand in 2050'
March 31, 2014 09:04 AM - Zoraida Portillo, SciDevNet
Fish catches will need to increase by only 3.4 per cent to meet global dietary demand in 2050, according to a study predicting how climate change will affect marine ecosystems. The authors warn that achieving this will require the wider implementation of sustainable harvesting, such as technological developments to reduce dependence on wild stock for farmed fish feed, and more-effective distribution of wild fish products from regions with a surplus to those with a deficit.
Scientists develop system to filter water using plant sticks
March 18, 2014 01:21 PM - Yao-Hua Law, SciDevNet
Scientists from the Massachusetts Institute of Technology (MIT) in the United States are working with their counterparts in developing countries to produce an "economical and efficient" means of filtering out bacteria from water using plant xylem that normally transports water and nutrients from the soil. The novel technology could provide a solution to the burden of water-borne diseases in East Asia and the Pacific where about 180 million people lack access to safe water supply, according to the UNICEF (UN Children's Fund).
Warmer years linked to more malaria in tropical highlands
March 13, 2014 01:53 PM - Pablo Correa, SciDevNet
[BOGOTA] People in densely populated highlands of Africa and South America — who have so far been protected from malaria by cooler temperatures — may be seeing more of the disease as the climate changes, according to a study in Science (6 March).
Challenges and a call for Conservation Cooperation in the Arab world
March 8, 2014 08:31 AM - Mark Henley, SciDevNet
The Arab region's best chance of facing the challenges of food insecurity, water scarcity and natural disasters lies in collaborating on environmental preservation, a study says. The study, published in The Lancet (20 January), argues that current academic discussions about health, population and development in the Arab region fail to convey the true level of urgency.
Crop Pests "Vastly Underestmated' Warns Study
March 6, 2014 03:22 PM - Sci Dev Net Contibutor, SciDevNet
The number of different pests plaguing crops in the developing world may be vastly underestimated, contributing to severely reduced harvests in some of the world’s most important food-producing nations, say researchers.
Scientists advocate protective deep-sea treaty
February 28, 2014 10:00 AM - Nick Kennedy, SciDevNet
A new international agreement is needed to police the exploitation of the deep ocean because of the rising threats of deep-sea mining and bottom trawling for fish, say scientists. Speakers at a symposium this month (16 February) urged the UN to negotiate a new treaty for the deep ocean to supplement the UN Convention on the Law of the Sea.
