Budget 2020: enough cash for trees and soil?

Visit the University of Derby blog for this article I wrote about the new UK budget in March 2020. It’s just over a week since the Chancellor of the Exchequer Rishi Sunak unleashed his ambitious ’spending spree’ budget, marking an end to austerity as a UK economic policy. Instead there …

Experimental data of bio self-healing concrete incubated in saturated natural soil

The provision of suitable incubation environments is vital for successful implementation of bio self-healing concrete (bio-concrete). We investigated the effect of soil incubation to examine if the self-healing process can be activated in comparison with the conventional incubation environment (water). The data was collected from laboratory-scale experiments conducted on mortar …

Microbiological self-healing of structural concrete underground incubation for geotechnical applications

Concrete is the most used construction material worldwide for infrastructure projects. Due to deterioration, regular maintenance works are necessary to seal the concrete cracks and restore durability. In Europe, infrastructures such as tunnels, bridges and earth retaining walls alone cost approximately 5 billion EUR per year. Self-healing strategies (particularly bacterial-based …

The Influence of Trees, Shrubs and Grasses on Micro-Climate, Soil Carbon, Nitrogen and CO2 Efflux: Potential Implications of Shrub Encroachment for Kalahari Rangelands

Shrub encroachment is a well-documented phenomenon affecting many of the world’s drylands. The alteration of vegetation structure and species composition can lead to changes in local microclimate and soil properties which in turn affect carbon cycling. The objectives of this paper were to quantify differences in air temperatures, soil carbon, …

Integrating microbiomics into peatland management and restoration

Peatlands are Important global carbon stores but are also sensitive climatically controlled ecosystems dependent on the maintenance of high water tables. Consequently they are under threat in warmer drier future climate conditions. The natural resilience of peatland systems and the potential to engineer resilience through peatland restoration are therefore important …

Microbial transport and soil integrity in drylands

Dryland soils are particularly vulnerable to erosion because of low plant cover and low organic matter which is linked with water availability and biological constraints. It is increasingly recognised that dryland soils can be managed to minimise erosion, which has benefits such as increasing soil fertility, carbon storage, and prevention …
