Between floods and forests is a matter of probability

,
Properly managing forests and preventing floods requires a paradigm shift, a Canadian study explains. That means replacing the deterministic approach with probability analysis and take all factors into account

Climate change is behind record drought in the Amazon Basin

,
Without climate change, the Amazon Basin would not have experienced the exceptional agricultural drought that has affected the area around the region's main river, an international study finds

Analysis of a river in Congo reveals carbon dynamics

,
As a tributary of the Congo River, the Ruki provides one-fifth of the dissolved carbon in the region's main waterway. A figure that suggests a lower sequestration capacity by the local forest, says a research
Nanopesticides were developed to ensure efficient distribution and lower environmental impact than traditional products. Photo: Aqua Mechanical CC BY 2.0 DEED Attribution 2.0 GenericAqua Mechanical CC BY 2.0 DEED Attribution 2.0 Generic

“Further investigation is needed on nanopesticides,” Dutch researchers say

Crop yield history reveals details of soil health

,
A study by the University of Michigan reveals the link between agricultural yield and soil quality. Using a new metric, key information can be obtained to plan agricultural strategies while reducing environmental impact

Atlantic Forest, Brazil, 82% of tree species could disappear

,
In the forest area spanning the southeastern region of Brazil, two-thirds of all species and more than four-fifths of endemic ones are threatened with extinction
Strategies such as extending the lifespan of infrastructure and recycling waste with subsequent transformation into inputs enable urban agriculture to largely reduce its climate impact.

Urban agriculture generates an excessive carbon footprint. Here’s how to avoid it

,
Agriculture developed in urban spaces can have six times the climate impact of traditional agriculture, explains a University of Michigan study. Some tricks, however, make it possible to solve the problem
In tropical forests, lianas tend to suffocate trees by restricting their growth. Photo: Andreas Kay CC BY-NC-SA 2.0 DEED Attribution-NonCommercial-ShareAlike 2.0 GenericAndreas Kay CC BY-NC-SA 2.0 DEED Attribution-NonCommercial-ShareAlike 2.0 Generic

Lianas and climate change limit forest restoration

,
In tropical forests, rising temperatures promote the spread of lianas that smother trees by limiting their growth, an Australian study says. With obvious consequences for carbon sequestration

The impact of agricultural deforestation on biodiversity is not the same everywhere

,
Some features promote the resilience of certain species to the effects of deforestation, a Peking University study has found. But biodiversity conservation is also affected by local agricultural history
