Guardian -- "Food security: rising prices, climate change and a growing population"

The Guardian holds a periodic news round up and forums under their "Poverty Matters" series.

Below is a sample of the issues now being discussed:

Rising commodity prices, a changing climate and a growing population have combined to push food security to the top of the international agenda, and have also dominated coverage on the Global development site this week.

Our Global food crisis interactive highlights the big issues in the current food debate, through blogs, features, video, galleries and audio reports.

Meanwhile, Felicity Lawrence, who travelled to Guatemala, Argentina and the US, explores the workings of the global food system and its impact on the poor.

In Guatemala, she discovers how the system is failing poor people working in the agro industry, despite the country being a leading agro-exporter. She also looks at the impact of a changing climate on the country's smallholder farmers and how the drive for biofuels is pushing more people into poverty.

She also reports on concerns over Chinese land acquisitions in Patagonia, Argentina, and the strain this could put on the region's water resources.
