Overview of hydrogen production processes: Health and environmental impact

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Hydrogen is traditionally regarded as a cornerstone in the path to a sustainable energy economy. However, there are substantial differences in the inclusion of environmental and health effects across the hydrogen production pathways, due to different feedstocks, technologies, and byproduct emissions.

Intensifying Drought Patterns and Agricultural Water Stress in Erbil Governorate, Iraq: A Spatiotemporal Climate Analysis

Global Challenges, EarlyView.
ABSTRACT Drought is a prolonged lack of rainfall that causes water shortages for agricultural land by reducing soil moisture and limiting crop yields. This study assesses the impacts of drought in Erbil, Iraq, using 28 years of data from the southern, central, and northern regions.

Potential of Biochar to Alternate Soil Properties and Crop Yields 3 and 4 Years after the Application

Agronomy, 2020
Several studies have reported that biochar can improve soil properties which are linked with higher crop yields and this effect is long-term. This paper aimed to study the effects of biochar (0, 10 and 20 t ha−1) and its combinations with N-fertilization

Land use driven change in soil pH affects microbial carbon cycling processes

Nature Communications, 2018
Land use intensification could modify microbial activity and thus ecosystem function. Here, Malik et al. sample microbes and carbon-related functions across a land use gradient, demonstrating that microbial biomass and carbon use efficiency are reduced ...

Assessing the Sustainability of Community‐Managed Irrigation Systems Using Multicriteria Analysis and Sustainability Indicators in Northern Ethiopia: A Holistic Approach

Irrigation and Drainage, EarlyView.
ABSTRACT Reservoir‐based irrigation schemes (RBISs) have been developed to minimize the adverse effects of moisture stress and improve the livelihoods of smallholder farmers in semi‐arid regions. However, many RBISs perform below expectations. A multistage expert elicitation approach and an indicator‐based Sustainability Assessment of Food and ...

Surface Energy Flux Estimation in Two Boreal Settings in Alaska Using a Thermal-Based Remote Sensing Model

Remote Sensing, 2020
Recent Arctic warming has led to changes in the hydrological cycle. Circum-Arctic and circumboreal ecosystems are showing evidence of “greening” and “browning” due to temperature warming leading to shrub encroachment, tree mortality and deciduousness ...
