How Solar power is bringing food security to Africa
November 25, 2016 11:54 AM - Joe Ware , The Ecologist

Malawi is one of the poorest countries in the world. Ninety per cent of Malawians live in rural areas; agriculture makes up 80 per cent of the labour force and 80 per cent of its exports. With so many people reliant on growing things from the ground, disruptions to the climate threatens the wellbeing of an entire nation.

For centuries Malawian farmers have learned the patterns of the seasons - when to plant their seeds in order to capture the rains that watered the ground and brought forth food to eat and sell. But this life-saving knowledge is becoming worthless, as rainfall patterns are distorted by a changing climate and the El Nino weather event, which this year created the worst food crisis in 25 years.

The Psychology Behind Climate Change Denial
October 5, 2016 06:53 AM - Uppsala University

Climate change is a serious threat to humans, animals, and the earth’s ecosystems. Nevertheless, effective climate action has been delayed, partly because some still deny that there is a problem. In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem.

In the scientific community there is a strong consensus that humans have significantly affected the climate and that we are facing serious challenges. But there is a lot of misinformation about climate change in circulation, which to a large part is created and distributed by organised campaigns with the aim of postponing measures that could combat climate change. And there are people who are more prone than others to trust this misinformation.

Previous research has consistently shown that it is more common among politically conservative individuals to deny climate change. In her thesis, Kirsti Jylhä has investigated this further and in more detail. Her studies included ideological and personality variables which correlate with political ideology, and tested if those variables also correlate with climate change denial.

The Great Green Wall of Africa

Llowell Williams, Care2

Though a border wall with Mexico is currently a matter of serious discussion in the United States, the aim of which is to prevent the physical movement of people (with few other apparent “benefits”), some walls can actually bring together and preserve communities, rather than divide them.

In only five years, the UN says, around 60 million Africans may be displaced as their land ceases to be arable, a potential humanitarian disaster the scale of which would be unprecedented. This would be devastating to a huge portion of the African continent not only ecologically and economically but socially as well.

That’s where Africa’s ingenious Great Green Wall comes in.

Experts at the United Nations say without action, desertification may claim two-thirds of Africa’s farmlands in under a decade. The Great Green Wall, however, was conceived as a wide-reaching strategy to halt Northern Africa’s rapidly advancing Sahara Desert.

The Great Green Wall, once complete, will stretch an incredible 4,400 miles from Senegal in West Africa to the East African nation of Djibouti. Instead of bricks and mortar, the wall will be made of trees and other vegetation, including plants that can be eaten or used to create medicine.
