Malawi farming experiment shows how simple changes can boost maize yields and improve soil

    By Alan Dixon, University of Worcester     Malawi’s increasingly unpredictable rainfall and higher than usual temperatures are causing problems for smallholder farmers. Soil erosion has increased, causing soil fertility and water availability to decline. Crops often fail. Farmers are already struggling financially. Many farm only one crop: maize. They can’t easily afford chemical fertilisers that would boost the soil’s fertility and sustain yields. Agriculture accounts for just […]

African elephants address one another with name-like calls − similar to humans

Elephants have close social bonds, which may have led to the evolution of name-like calls. Michael Pardo     By Mickey Pardo, Colorado State University     What’s in a name?

Hunter-gatherer diets weren’t always heavy on meat: Morocco study reveals a plant-based diet

      By Zineb Moubtahij, Leiden University     About 11,000 years ago, humans made a major shift from hunting and gathering to farming. This change, known as the Neolithic Revolution, dramatically altered our diets. For decades, scientists have thought that pre-agricultural human groups ate a lot of animal protein. But analysis has always been hampered by a scarcity of well-preserved human remains from Pleistocene sites. So, in fact, […]

Hydropower damages river systems in Africa: how more solar and wind power can solve this problem

      By Angelo Carlino, Carnegie Science; Andrea Castelletti, Polytechnic University of Milan, and Rafael Schmitt, Stanford University     Across the African continent, more than 300 new hydropower projects are planned to meet the growing demand for electricity. Some of these will require big dams, which can have major negative environmental impacts. Another looming problem with hydropower is that the water cycle is affected by climate change. Water […]

By not mining vital minerals, NZ is ‘offshoring its own environmental footprint’ – is that fair?

Getty Images     By Martin Brook, University of Auckland, Waipapa Taumata Rau     When Resources Minister Shane Jones recently unveiled his draft strategy for mineral mining, it was quickly criticised by the Labour opposition as “taking New Zealand backwards”. One environmental group even called it a “love letter to mining companies”. But the government’s ambition to double the sector’s export value to NZ$2 billion by 2035, with flow-on effects […]

Climate Change threatens Namibia’s Agricultural Sector

    The agricultural sector is vital for sustaining livelihoods in Namibia but faces significant climate change challenges. Namibian farmers frequently experience adverse rainfall seasons, leading to floods, droughts, and pest and disease outbreaks. Droughts, occurring every other year with varying severity, have particularly harmed crop and livestock farmers, reducing productivity and income due to poor yields, livestock performance, and market prices.   Technical Advisor of Livestock and Rangeland from […]
