Forest fires drive expansion of savannas in the heart of the Amazon

"...The authors studied an area of floodplains on the middle Negro River near Barcelos, a town about 400 km upstream of Manaus, the capital of Amazonas state, where areas of white-sand savanna are expanding, although forest ecosystems still predominate. They blame the increasing frequency and severity of wildfires in the wider context of global climate change..."

Forests on caffeine: coffee waste can boost forest recovery

"...The researchers also found that after two years, nutrients including carbon, nitrogen and phosphorous were significantly elevated in the coffee pulp treated area compared to the control. This is a promising finding given former tropical agricultural land is often highly degraded and poor soil quality can delay forest succession for decades..."

Federal Government Announces $185 Million For New Agricultural Climate Solutions Program

"...Each hub will centre on farms, where farmers and researchers can co-develop best practices, including cover crops, intercropping, conversion of marginal land to permanent cover, shelterbelts, nutrient management, and inclusion of pulses in rotations. Applicants will need to demonstrate their ability to engage with researchers and develop plans for knowledge transfer and adoption among their peers. Agriculture and Agri-Food Canada will host regional information sessions over the coming weeks..."

Corn belt farmland has lost a third of its carbon-rich soil

"...Productive agricultural soils are vital for producing food for a growing global population and for sustaining rural economies. However, degradation of soil quality by erosion reduces crop yields. Thaler and his colleagues estimate that erosion of the A-horizon has reduced corn and soybean yields by about 6%, leading to nearly $3 billion in annual economic losses for farmers across the Midwest..."

Facts on the ground: How microplastics in the soil contribute to environmental pollution

"...For their study, the scientists examined four soil types corresponding to different agricultural practices: soils from outside and inside a greenhouse (GS-out and GS-in, respectively), mulching (MS), and rice field soil (RS). Of these, the former three samples represented the use of polyethylene film, while the RS sample represented little to no use of plastic. To minimize the effect of non-agricultural sources of MP, scientists collected the samples from rural farmlands during the dry season..."

Study: Integrating satellite and socioeconomic data to improve climate change policy

"..."Extreme climate events, such as drought and flood, changes in urban and rural population and economic conditions are driving the changes from forest to shrub land in the southeast region of Bangladesh," Jain said. "Here, the locals earn their livelihood by using land, lumber and fuel resources from forests. However, deforestation may be controlled by implementing simple policies such as road improvement, which can provide the people with a means to obtain alternative fuels and livelihoods that are not as dependent on forests..."
