Land restoration is the process of ecological restoration of a site to a natural landscape and habitat, safe for humans, wildlife and plant communities. For reducing run-off and erosion in sodic soils, reclamation is a common practice. Reclamation of sodic soils involves replacement of exchangeable sodium by calcium. The invention relates to methods for land improvement (soil reclamation), first for soil remediation comprising the steps of (i) placing a material useful for improving soil and an explosive in the soil, and (ii) mixing the materials which are useful for reclaiming the soil and the polluted soil by explosion. The contaminants are separated from all soil particles by a soil reclamation system and generate reusable soil and contaminant products.

The capacity for biochar to adsorb contaminants presents opportunity to add value to land contaminated by heavy metals (Beesley and Marmiroli, 2011), to manage pH (Kim et al, 2013) or immobilize toxic organic compounds (remediation). In conjunction with other measures it has the potential to help restore valuable soil functions in degraded land (restoration).
Floods after bushfires: rapid responses for reducing impacts of sediment, ash, and nutrient slugs

A wide range of practical measures can reduce the impacts of ash and sediment runoff (Commonwealth of Australia 2020). Australia’s experience with landcare provides models of community and government partnerships in large-scale land restoration (Campbell, Alexandra, and Curtis 2018). However, treating all burnt areas may not be feasible, given the unprecedented scale of these fires. Technically, we know how to minimise erosion, using techniques like sediment traps made of earth, geo-fabrics, logs or straw bale barriers. These are especially useful near culverts that concentrate and accelerate flows off forest roads. These techniques are sometimes used to protect water supply catchments, or other high value areas after bushfires. However cost may be prohibitive over huge areas, unless funding programs are directed to waterway and catchment protection. While these are useful for employment in the affected regions, feasibility assessment and prioritisations of areas to treat would still be needed.
