Food forests offer better profits to farmers

Unprecedented climate change is causing a rethink on the way we grow our food. More and more farmers in India are looking at resilient food forests to sustain themselves, with reduced irrigation needs and improved productivity; and to help the country through the current agrarian crisis.

River turns drain, drowns villages in sorrow

Till four decades ago, Ghaggar river in Haryana and Punjab was the lifeline of the villages along its course. Incessant dumping of sewage and industrial effluents, however, has choked the life out of it and has reduced it to a drain or nullah, as locals call it, now. Its water has become unusable and those who come in contact with it, mostly farmers, contract skin ailments. Water-borne diseases such as jaundice and diarrhoea are common in settlements along the Ghaggar. Early greying of hair in children is another disturbing trend. Even the underground water has turned black or yellow in many places.

Cooking imposes heavy burden on rural women

She wakes up at 5am when it is still dark and the rest of the family is asleep. She walks 4 km to reach a hillock and starts gathering firewood. By daybreak, she is back and starts cooking for the family. What about water for cooking? That involves another trek.

Light pollution lures night-time pollinators away from plants

Populations of bees, bats, butterflies and other pollinators have been declining for decades due to habitat loss, disease, pesticides and climate change. Now, scientists have documented yet another threat to pollinators: night-time light pollution.

In a recent study in Nature, ecologists showed that plants growing near streetlights were pollinated far less often at night and produced fewer fruits than their unilluminated counterparts. In turn, this may compromise the efficiency of daytime pollinators in the same fields, the authors conclude.

Can CRISPR feed the world?

By 2040, there will be 9 billion people in the world. ‘That’s like adding another China onto today’s global population,’ said Professor Sophien Kamoun of the Sainsbury Laboratory in Norwich, UK. Prof. Kamoun is one of a growing number of food scientists trying to figure out how to feed the world. As an expert in plant pathogens such as Phytophthora infestans – the fungus-like microbe responsible for potato blight – he wants to make crops more resistant to disease. Potato blight sparked the Irish famine in the 19th century, causing a million people to starve to death and another million migrants to flee. European farmers now keep the fungus in check by using pesticides. However, in regions without access to chemical sprays, it continues to wipe out enough potatoes to feed hundreds of millions of people every year.‘Potato blight is still a problem,’ said Prof. Kamoun. ‘In Europe, we use 12 chemical sprays per season to manage the pathogen that causes blight, but other parts of the world cannot afford this.’

Micro Solutions For A Macro Problem: How Marine Algae Could Help Feed The World

Our planet faces a growing food crisis. According to the United Nations, more than 800 million people are regularly undernourished. By 2050, an additional 2 to 3 billion new guests will join the planetary dinner table. Meeting this challenge involves not only providing sufficient calories for every person, but also assuring a balanced diet that includes the protein and nutrients that are essential to good health. In a newly published study, we explain how marine microalgae could be a sustainable solution for solving global macro-hunger.
