BBC’s Panorama reporter Paul Kenyon goes undercover as a cocoa trader in West Africa and discovers children as young as seven working long hours on cocoa farms, helping to make the chocolate we love so much. He buys a tonne of cocoa made with child labour, and sees how easy it is to sell it into the supply chain which leads to our high streets.

In a village in India’s poorest state, Bihar, farmers are growing world record amounts of rice – with no GM, and no herbicide. Is this one solution to world food shortages?

Sumant Kumar was overjoyed when he harvested his rice last year. There had been good rains in his village of Darveshpura in north-east India and he knew he could improve on the four or five tonnes per hectare that he usually managed. But every stalk he cut on his paddy field near the bank of the Sakri river seemed to weigh heavier than usual, every grain of rice was bigger and when his crop was weighed on the old village scales, even Kumar was shocked.

This was not six or even 10 or 20 tonnes. Kumar, a shy young farmer in Nalanda district of India’s poorest state Bihar, had – using only farmyard manure and without any herbicides – grown an astonishing 22.4 tonnes of rice on one hectare of land. This was a world record and with rice the staple food of more than half the world’s population of seven billion, big news.

It beat not just the 19.4 tonnes achieved by the “father of rice”, the Chinese agricultural scientist Yuan Longping, but the World Bank-funded scientists at the International Rice Research Institute in the Philippines, and anything achieved by the biggest European and American seed and GM companies. And it was not just Sumant Kumar. Krishna, Nitish, Sanjay and Bijay, his friends and rivals in Darveshpura, all recorded over 17 tonnes, and many others in the villages around claimed to have more than doubled their usual yields.

Amid all the controversy over genetically-modified (GM) crops and their pesticides and herbicides decimating bee populations all around the world, biotechnology behemoth Monsanto has decided to buy out one of the major international firms devoted to studying and protecting bees. According to a company announcement, Beeologics handed over the reins to Monsanto back on September 28, 2011, which means the gene-manipulating giant will now be able to control the flow of information and products coming from Beeologics for colony collapse disorder (CCD).
