Triharmony/Trilemma of Nutrients Assets in tropical peatland

Written by

Osaki and colleagues have developed an innovative nutrient management system for tropical peatland in high groundwater levels, known as AeroHydro culture.

Peatland soils and water are characterised by low nutrient concentrations. Despite this, biomass in native tropical peatlands is abundant and has adequate nutrients. At Hokkaido University, Sumitomo Forestry Co Ltd, Japan, and BRIN, Indonesia, scientists studying nutrient cycling in peatlands have developed an innovative nutrients management system for agriculture. Their approach – AeroHydro culture – involves cultivation using high groundwater […]

Testing the waters in Italy: Identifying co-seismic groundwater changes

Gilberto Binda & colleagues examined data regarding earthquakes in the Appenines and the resulting hydrochemical changes in groundwater

Co-seismic groundwater changes can have profound implications for water quality. Many studies have investigated earthquake-induced hydrochemical changes; however, the underlying mechanisms remain disputed. Dr Gilberto Binda and colleagues have shown that in the aquifers of the Italian Apennines, changes in water chemistry, temperature, and flow rate can follow earthquakes, and are for the large part transient. However, many changes are […]

Understanding water resources in Latin America and the Caribbean region using environmental tracers

The researchers examine the decline in surface water quality and quantity.

With approximately 660 million inhabitants, Latin America and the Caribbean region finds itself vulnerable to decreasing water availability in a changing climate. Increasing temperatures and abrupt land use changes, if not addressed, will continue the decline in surface water quality and quantity, thereby forcing greater dependence on groundwater extraction. Advancing studies into the availability, replenishment rates and quality of (ground) […]

Soil and groundwater contamination: An old and new issue needs to be solved

Written by

Industrial and agricultural waste contaminate the soil and groundwater.

Dr Ming Zhang is an innovation coordinator at Geological Survey of Japan, AIST. Alongside his research group, he is advocating the importance of using interdisciplinary tools for sustainable remediation of contaminated soil and groundwater. Their research has shown that cost-effective and environment-friendly technologies such as the use of microorganisms to degrade organic contaminants and the use of minerals to immobilise […]
