A metagenomic survey of soil microbial communities along a Rehabilitation chronosequence after iron ore mining.
Scientific Data, 2019Co-Authors: Markus Gastauer, Silvio Junio Ramos, Cecílio Frois Caldeira, Mabel Patricia Ortiz Vera, Kleber Padovani De Souza, Eder Soares Pires, Ronnie Alves, Guilherme OliveiraAbstract:Microorganisms are useful environmental indicators, able to deliver essential insights to processes regarding mine Land Rehabilitation. To compare microbial communities from a chronosequence of mine Land Rehabilitation to pre-disturbance levels from references sites covered by native vegetation, we sampled non-rehabilitated, rehabilitating and reference study sites from the Urucum Massif, Southwestern Brazil. From each study site, three composed soil samples were collected for chemical, physical, and metagenomics analysis. We used a paired-end library sequencing technology (NextSeq 500 Illumina); the reads were assembled using MEGAHIT. Coding DNA sequences (CDS) were identified using Kaiju in combination with non-redundant NCBI BLAST reference sequences containing archaea, bacteria, and viruses. Additionally, a functional classification was performed by EMG v2.3.2. Here, we provide the raw data and assembly (reads and contigs), followed by initial functional and taxonomic analysis, as a base-line for further studies of this kind. Further investigation is needed to fully understand the mechanisms of environmental Rehabilitation in tropical regions, inspiring further researchers to explore this collection for hypothesis testing.

Mine Land Rehabilitation in Brazil: Goals and techniques in the context of legal requirements
Ambio, 2018Co-Authors: Markus Gastauer, Joyce Reis Silva, Silvio Junio Ramos, José Oswaldo Siqueira, Pedro Walfir Martins Souza Filho, Cecílio Frois Caldeira, Antonio Eduardo Furtini NetoAbstract:Environmental legislation in many countries demands the Rehabilitation of degraded areas to minimize environmental impacts. Brazilian laws require the restitution of self-sustaining ecosystems to historical conditions but ignore the emergence of novel ecosystems due to large-scale changes, such as species invasions, extinctions, and Land-use or climate changes, although these novel ecosystems might fulfill ecosystem services in similar ways as historic ecosystems. Thorough discussions of Rehabilitation goals, target ecosystems, applied methods, and approaches to achieving mine Land Rehabilitation, as well as dialogues about the advantages and risks of chemical inputs or non-native, non-invasive species that include all political, economic, social, and academic stakeholders are necessary to achieve biological feasibility, sociocultural acceptance, economic viability, and institutional tractability during environmental Rehabilitation. Scientific knowledge of natural and rehabilitating ecosystems is indispensable for advancing these discussions and achieving more sustainable mining. Both mining companies and public institutions are responsible for obtaining this knowledge.

Mine Land Rehabilitation: Modern ecological approaches for more sustainable mining
Journal of Cleaner Production, 2018Co-Authors: Markus Gastauer, Joyce Reis Silva, Cecílio Frois Caldeira Júnior, Silvio Junio Ramos, Pedro Walfir Martins E Souza Filho, Antonio Eduardo Furtini Neto, José Oswaldo SiqueiraAbstract:Abstract Despite the urgent demand for sustainable mining, the revegetation and Rehabilitation of areas degraded by mining activities remain challenging. Uncertainties about species selection, the management and control of alien invasive species and monitoring procedures require ongoing multidisciplinary research. Modern functional and phylogenetic approaches in community ecology represent powerful tools to enhance the entire Rehabilitation process and to overcome these challenges, but methodologies that incorporate up-to-date phylogenetic information or knowledge about intraspecific variation along Rehabilitation trajectories must be developed. Functional and phylogenetic criteria may play an especially important role in guiding the definition of faster-growing, more resistant species mixtures that can be applied in mine Land revegetation and Rehabilitation. Limiting similarity approaches may help to reduce biological invasions, enabling native vegetation to outcompete alien invasive species and aiding in the development of enduring mechanisms for controlling such species in rehabilitated mine Land. Finally, incorporating phylogenetic and functional aspects into monitoring of the success of mine Land Rehabilitation with additional tools, such as remote sensing or metabarcoding, can enrich scientific knowledge about ecosystem functions such as nutrient cycling, community assembly and resource availability while providing sound information about the success of revegetation activities. In the middle to long term, research activities on these topics can provide valuable technical recommendations for all aspects of the management of rehabilitated ecosystems, thus contributing to more sustainable mining.

Assessment for soil improvement benefit of Land Rehabilitation in dump areas
Mathematical and Computer Modelling, 2011Co-Authors: Yingyi Chen, Yongjun ZhengAbstract:Land Rehabilitation can affect the environment of dump areas prominently. For example, it can improve the chemical properties of the soil in the dump. In order to discover the quantitative relationship between Land Rehabilitation and soil improvement, firstly, 14 kinds of physical and chemical properties of the soil in dumps are compared and analyzed, such as the soil's organic matter content, thickness of the soil layer, total nitrogen, available phosphorus, calcium, magnesium, sulphur and boron, rapidly available potassium, iron, copper, zinc and manganese, and pH. Secondly, according to different waste ages and different Rehabilitation ages and based on the theory of water and soil conservation and soil science and ecology resumption, the soil improvement benefit of Land Rehabilitation is studied by using the method of space as a substitute for time. Finally, this paper discusses the soil improvement benefit evaluation system of Land Rehabilitation in dump areas initially, then builds a soil improvement benefit evaluation model utilizing the gray relational analysis method. This research can provide the necessary test data, scientific basis and evaluation method for Land Rehabilitation projects in dump areas. The results show that the soil improvement benefit is directly proportional with the different waste ages and the different Rehabilitation ages. In addition, human activity is also an important factor for the improvement benefits of Land Rehabilitation.

Monitoring of Landscape change for waste Land Rehabilitation in Haizhou opencast coal mine
WSEAS Transactions on Information Science and Applications archive, 2009Co-Authors: Yingyi ChenAbstract:Land Rehabilitation is being carried out throughout the whole country. But in many areas, the main purpose of Land Rehabilitation is to increase the overall cultivated Land area which neglects the eco-construction. Important tasks of modern Landscape ecology are to monitor and assess natural resources, to examine the impacts and effects of human intervention and, last but not least, to observe the state of the environment over long periods of time. The objective of this research was to create a method for Land Rehabilitation project using Landscape ecology by combining Geographical Information Systems (GIS) and Landscape Ecology Analysis (LEA). GIS technologies were developed for the digital preparation and analysis of historical maps, and subsequent digital Land use mapping. The Landscape spatial pattern and influence on Landscape were expressed by dominance index, contagion index, cohesion index, etc. Applying those Landscape ecology indexes Landscape spatial pattern influence caused by the Land development and Rehabilitation planning of Haizhou coal mine waste area was studied by comparing Landscape characteristics between those before and after planning implementation. The analysis of the structural Landscape changes proved to be an important aspect.
