Subsidence, or the lowering of the land surface due to the removal of material from underground, impacts 25 percent of the Planet's population, U.S. researchers have found
The causes of floods are multiple and involve several variables interacting with each other. Photo: somersetpedia.paul CC BY-SA 3.0 DEED Attribution-ShareAlike 3.0 Unportedsomersetpedia.paul CC BY-SA 3.0 DEED Attribution-ShareAlike 3.0 Unported

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
During flood events, cover crops reduce the release of nitrate and phosphorus from the soil. SSGT Paul Griffin Release Status: Released to Public Combined Military Service Digital Photographic FilesPaul Griffin Release Status: Released to Public Combined Military Service Digital Photographic Files

Cover crops are a barrier against agriculture-based pollution

,
According to a U.S. study, the application of cover crops on a share of cultivated land reduces the maximum concentration of ammonia and phosphorus by more than 30 percent. Whose accumulation is favored by floods
Increasing urbanization results in the conversion of natural ecosystems into residential areas that incorporate green areas such as parks or lawns. Photo: Md.

Urbanization promotes increasing emissions from the soil

,
As a result of urbanization, soil nitrous oxide emissions increase 153%, according to a new study. At the same time, the ability to absorb methane is reduced

Solar farms may encourage soil erosion in U.S.

,
Virginia Tech researchers will analyze erosion risk in the state's solar installations. In the U.S., the problem is real. But several solutions are available
The expansion of large-scale agriculture is making the plains of South America more vulnerable to flooding. Photo: Andy Abir Alan Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)Andy Abir Alan Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)

Extensive farming increases flooding in South America

,
According to an Anglo-Argentine study, the spread of large-scale agriculture over the last four decades has favoured the rise of water tables in the plains of South America. Substitution of native vegetation has been crucial factor
The Avcılar neighborhood in Istanbul stands on land particularly prone to liquefaction, a widespread phenomenon in several urban areas of Turkey. Photo: Maderibeyza Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)Maderibeyza Attribution-ShareAlike 3.0 Unported (CC BY-SA 3.0)

Soil liquefaction is still a big issue in Turkey

,
There is more than just the force of nature behind the widespread building collapses experienced during earthquakes in Turkey. Poor construction practices and bad choices in fact foster soil fragility

Climate and drought are the perfect recipe for disruption (not just) in California

,
During extended drought periods, soil loses its ability to absorb water, writes The New York Times. When rain occurs, landslide risk increases. A combination of phenomena that climate change makes increasingly frequent
