Over the last two decades, there has been growing interest on the effects of agricultural practices on soil biology in Europe. As soil biota are known to fluctuate throughout the season and as agro-environmental conditions may influence the effect of agricultural practices on soil organisms, conclusions cannot be drawn from a single study. Therefore, integrating the results of many studies in order to identify general trends is required. The main objective of this study was to investigate how soil biota are affected by repeated applications of organic amendments (i.e.

The assessment of microbial functional diversity is an important indicator of soil quality. Different methodological approaches are currently used; among them are enzyme activities (EA) and CLPP (community level physiological profile) techniques (e.g. MicroResp™ MR).

Non-vascular plants such as mosses, lichens and especially microalgae are widespread in terrestrial ecosystems, but their contribution in the nutrient cycling and energy budget of soil food webs is generally neglected. Despite a relatively low total biomass, soil microalgae can be very productive and contribute to the diet of many soil decomposers such as Collembola. Using 15N/14N ratios we showed that phycophagy is of particular importance for Collembola in extreme habitats like rock surfaces, or seasonally during the wintertime.

Inspired by the energy democracy movement, this conceptual review critically explores relationships between concentrated or distributed renewable energy and political power. Advocates assert that because the renewable energy transition is fundamentally a political struggle, efforts to shift from fossil fuels and decarbonize societies will not prove effective without confronting and destabilizing dominant systems of energy power.

Looking back from 2050, this article is written in the form of a fictional speech reflecting on the impressive progress made by 2050 towards achieving the global goal of zero net emissions. The speaker also highlights the severe and ongoing ecological damage and human suffering caused by the failure to reduce emissions with sufficient urgency in the first quarter of the 21st Century – and the ongoing challenge of implementing the actions required to bring global temperatures back below 1.5 degrees. The speech identifies the following key drivers of the ‘great 21st century energy transition’.

In development engineering, practitioners often strive to empower local communities through technology. Effective adult education principles worked well with medium-tech mapping solutions. Local people used these skills to identify and solve their own development problems.

Since 2000, mobile phone technologies have been widely adopted in many developing countries. Existing research shows that use of mobile phones has improved smallholder farmers’ market access and income. Beyond income, mobile phones can possibly affect other dimensions of social welfare, such as gender equality and nutrition. Such broader social welfare effects have hardly been analyzed up till now. Here, we address this research gap, using panel data from smallholder farm households in Uganda.

Corrosion inhibition performance of an environmentally friendly compound, 8-hydroxyquinoline (8-HQ), on X60 steel was investigated in 15% hydrochloric acid (HCl), which simulate oil well acidizing environment. Efficacy of the inhibitor was examined utilizing weight loss, potentiodynamic polarization (PDP), electrochemical frequency modulation (EFM), linear polarization (LPR), and electrochemical impedance spectroscopy (EIS). Results show increased inhibitor efficiency with increase in concentration of 8-HQ and was further enhanced when iodide ions were added.

The versatile use of droplet coagulation to recycle complex waste resources (fly ash FA, rice husk ash RHA and alum sludge AS) was investigated. Monodisperse microspheres were shaped, creating higher impact on the applicability of the waste resources. In order to obtain a suspension with appropriate rheological properties, pre-processing was required for the AS powder in contrast to the RHA and FA powders. Furthermore, the impact of the shaping process and waste stream properties on the calcination and sintering was determined and correlated to the microstructure of the sintered spheres.

Metal-organic framework (MOF) materials are porous materials with high surface area that offer enormous flexibility of design and tailoring of its surface properties to be used in diverse chemical processes. Most of the reported properties of MOF materials were evaluated in powder materials produced in small scale where the synthesis has been optimized to obtain crystalline powders. Ideally, the industrialization of these materials will also be associated to efficient scalable synthesis protocols.
