Special Issue Information

Dear Colleagues,

Environmental degradation is becoming increasingly intense around the world. Extreme weather events potentiate the degradation processes, causing environmental and socio-economic damage. In this way, a greater understanding of these degradation processes is necessary, especially in tropical ecosystems, in order to improve their prediction, as well as mitigate their effects. The use of complex systems modeling and advanced ecosystem assessment methods help with their prediction. Aiming at the sustainability of tropical ecosystems, the development of new materials is also essential, especially within the context of the circular economy, aiming at the recovery of degraded areas.

In this Special Issue, we are interested in contributions related to recent studies at the frontier of knowledge aimed at the sustainability of tropical ecosystems. In particular, we encourage our colleagues to submit studies exploring the following topics:

  • Extreme events with an emphasis on tropical weather conditions, which may also include temperate conditions for comparison purposes;
  • Degraded areas: assessment, mitigation and adaptation;
  • Instrumentation and advanced methods of environmental assessment;
  • Simulation/modeling of complex systems;
  • New materials: remediation/recovery involving soil/water systems;
  • Bio-inputs;
  • Circular economy applied in the context of remediation/recovery of degraded areas.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.

In waste disposal areas, soils can be used as environmental protection barriers to retain potentially toxic metals. Although most studies focus on lateritic soils, it is still of interest to evaluate other soil types, aiming to select the best materials among those available near the contamination area, reducing costs and construction efforts. This paper characterizes and evaluates the behavior of 13 soil materials collected in a region (Ribeira Valley, Brazil) with a history of improper mining waste disposal for the retention of lead (Pb) and cadmium (Cd) and their possible use as environmental protection barriers. All soils were acidic, kaolinitic, with negatively charged particles. Soils were grouped into three classes according to soil properties, such as particle size distribution, cation exchange capacity (CEC), and specific surface area (SSA), using cluster and principal component analysis. The Pb and Cd adsorption capacities ranged from 288 to 479 µg g−1 and 207 to 326 µg g−1, respectively, obtained from batch equilibrium tests. In general, all soils presented suitable characteristics for the retention of Pb and Cd, but four of them (1 to 4) showed the highest adsorption capacities, probably due to their larger SSA, CEC and percentage of fines (clay + silt).
