ENVIRONMENT-CANADA: Western Farmers Battered by Worst-Ever Drought

Canadian farmers on tiny, green Prince Edward Island are stacking bales of their fresh-cut hay onto rail cars and shipping them 5,000 kilometres to feed hungry cattle in dusty Alberta and Saskatchewan, suffering their worst droughts in history.

SCIENCE: Different Visions Compete to Control Africa’s Witchweed

A biotechnology approach to controlling African farmers' persistent enemy - witchweed - may be getting the upper hand on more "ecological" solutions to the problem, thanks to funding from Western agencies.

HEALTH: Big Promise, Small Prospects Seen in Genetic Technologies

Genetic research could help save millions of lives in poor countries by helping defeat diseases like malaria, tuberculosis, and HIV/AIDS, says the World Health Organisation (WHO). Some experts say faith in the genomic industry -- with its emphasis on high technology and profits -- is misplaced.

ENVIRONMENT: Biotech Industry Cautioned Over Good Intentions

Biotechnology companies intend to foster the development of medicines for the world's poorest people and ensure that developing countries benefit when local plants or remedies are used for new drugs. In exchange, they want open markets, harmonised regulations, and respect for their intellectual property rights.

ENVIRONMENT: Mining Companies Embrace Sustainability

Some of the world's biggest mining and metals corporations publicly committed to sustainable development at a Global Mining Initiative Conference here this week. Activists greeted the promise with scepticism.

ENVIRONMENT: NGO Treaty Aims to End Patenting of Life Forms
