High-frequency water quality measurements in streams and rivers have expanded in scope and sophistication during the last two decades. Existing technology allows in situ automated measurements of water quality constituents, including both solutes and particulates, at unprecedented frequencies from seconds to subdaily sampling intervals. This detail...

The world faces many threats, the climate crisis has reached the top of the political agenda (COP26) and the recent COVID19 pandemic has raised awareness of the fragility of socio-ecological systems. The time is right to seek new opportunities to consider how to enhance resilience to environmental and societal shocks, as reflected in the SG ambitio...

Rapid economic growth in Asia and especially in China, will lead to a huge increase of food waste (FW) production that is expected to increase by 278–416 million tonnes. Among various waste management practices, anaerobic digestion (AD) is a useful method to transform food waste, producing renewable energy/biofuel and bio-fertilizers. This review a...

Recent research suggests that groundwater overdraft can be mitigated by application of water onto agricultural lands for direct groundwater recharge. This technique is often called Agricultural Managed Aquifer Recharge (Ag-MAR) and is carried out in wintertime. Winter flooding of rice paddies could be considered as a form of Ag-MAR. Currently, it i...

Starting from October 2017, the hydrological balance of a 36 hectares’ rice area located in Lomellina (PV), where the practice of winter flooding has been adopted since 2004, has been under investigation. Flow meters were installed on the irrigation and drainage channels, piezometers were positioned inside and outside the study area, and a soil sur...

In Precision Agriculture electromagnetic induction (EMI) sensors are generally used to obtain soil electrical conductivity (EC) maps for the delineation of homogeneous management zones (MZ). EC measurements are related to many physical-chemical soil properties and, moreover, are average values referred to the soil depth explored by the sensor. Cons...

Hydrolysis is normally the rate limiting step for anaerobic digestion (AD). In this study, hyper-thermophilic (70 °C) pre-treatment of chicken manure under HRTs of 10, 5, 3, 2 and 1 d(s) was investigated to enhance the hydrolysis efficiency for biogas production. In-situ phase gas stripping was integrated into the pre-treatment reactor to remove am...
