Actual Acidity

The challenge of degradation of natural ecosystems because of human activity is considered by the world community to be the most serious problems facing mankind. As a result of mineral extraction, man-made landscapes and environmentally ruined areas replace natural habitats and agroecosystems; a whole spectrum of man-made processes are typical for such landscapes, which leads to a decrease in species richness and biological diversity within such areas. Degraded territories formed in the process of coal mining are often partially restored through remediation measures. During the implementation of the technical stage of remediation, substrates with different potential fertility having different environmental properties and quality are used. However, in quality assessment of remediated soils insufficient attention is paid to restoration of the environmental properties of the soils, namely their suitability for the existence of soil biota, which ensures the soil’s sustainability and vitality. The main indicators determining the productivity of remediated lands and the degree of their suitability for the existence of soil biota are values of actual acidity and degree of salinity. An assessment of the quality of reclaimed lands of  the Ordzhonikidzevsky ore mining and processing enterprise was carried out on the example of the Zaporizhsky open-cast mine with the aim of assessing the possibility of their economic use and suitability for the existence of soil biota , as well as to make recommendations for further rational use. It was found that  main characteristics  of the study area (capacity of bulk humic layer, content of humus in the bulk layer, content of physical clay in the bulk humic layer and in the subsoil, average soil density in the meter bulk layer, salinity of the bulk humic layer and subsoil, composition and properties of subsoil), of the Zaporizhzhya quarry's reclamation is suitable for the further settlement and successful existence of the soil biota. It is concluded that as a result of the technical stage of reclamation, an artificial reclaimed soil was obtained, which according to its characteristics is similar to the primary zonal soils that were located in this area prior to mining; the recultivated soil has somewhat lower fertility and greater salinity at the lower horizons, but is capable of performing ecological functions and can not only be used for economic purposes, but also perform ecological functions, serving as an environment for the existence of soil biota.

Economic Use

Environmental protection, rational use of natural resources and ensuring the ecological safety of human life are integral conditions of sustainable economic and social development of European Union. Mining industry is one of the powerful factors that leads to degradation of various native landscapes. Withdrawal of agricultural land from intended use results from the minerals extraction. Instead them man-made landscapes (dumps and quarries) are formed, as well as destructive territories characterized by subsidence, contamination with toxic compounds, decrease of species richness and biological diversity. Disturbed territories formed during mining process are usually partially restored with remediation. Remediation process consist of two stages: technical and biological. In the result of technical stage implementation, substrates with different potential fertility having different environmental properties and quality are formed. However, in quality assessment of remediated soils insufficient attention is paid to restoration of the soil environmental properties, namely their suitability for existence of soil biota, which ensures the soil sustainability and vitality. Purpose of the presented work was to assess quality of remediated lands in condition of Ordzhonikidzevsky manganese quarry (Olexandrovskiy and Zaporizhkiy careers) on the possibility of their use and suitability for soil biota existence, as well as providing recommendations for further rational economic use of them. Data on chemical properties of reclaimed soil were collected on the sites of performed recultivation. Humus content was determined according to DSTU 4289: 2004, analysis of water extraction was carried out according to GOST 26425-85, GOST 26426-85, GOST 26427-85, GOST 26428-85. The study is novel in that it is proposed to take into account environmental conditions for existence of soil invertebrates which play a crucial role in formation of agro-system stability mechanisms. The main indicators determining the productivity of remediated lands and the degree of their suitability for soil biota existence are values of actual acidity and salinity degree. An assessment of the reclaimed lands quality on the Ordzhonikidzevsky ore mining and processing enterprise was carried out on the example of Zaporizhsky and Olexandrovsky open-cast workings on the possibility of their economic use and suitability for the soil biota existence, as well as recommendations for further rational use. It was found that studied areas by the main characteristics are suitable for the further settlement and successful existence of soil biota. It is concluded that as a result of the technical stage of reclamation, an artificial reclaimed soil was obtained, which, according to the main characteristics, is similar to native zonal soils located in this area prior to mining; the recultivated soil has somewhat less fertility and greater salinity of lower horizons, but it is able to perform ecological functions and can not only be used for economic purposes, but also perform ecological role, serving as an environment for existence of soil invertebrates.

Proceedings of the International conference (ИнтерКарто. ИнтерГИС, Russia) devoted to geographical information systems for sustainable development of territories have been published annually since 1994. The articles discuss theoretical and methodological aspects of geoinformation support for environmental, economic and social aspects of sustainable de­velop­ment, issues of geoinformatics, cartography, remote sensing of the Earth, problems of environmental sustainability and environmental impact assessment. Over a quarter of a century, the conference proceedings got more than 125 articles related to the use of geoinformation technologies to the study and mapping of vegetation. The review of proceedings gives the concrete examples how to solve problems of vegetation mapping using GIS, it is focused on publications providing some examples of GIS appli­cation to the vegetation studies. The review is organized into thematic sections according the field of application of Geoinformatics: 1.Vegetation, 2. Dynamics, state and ecological functions of vegetation, 3. Biodiversity and its assessment, 4. Plant resources, 5. Monitoring of vegetation. The Vegetation section contains publications on vegetation studies and mapping performed for some regions of Russia — the North of the Far East, the Republic of Sakha (Yaku­tia), the Tyva Republic, Central Siberia, and others. More than half of the articles are devoted to vegetation dynamics, state and ecological functions of vegetation at different hierarchical levels. Some papers present the results of the studies based on new types of information sources (photographs) and visualization methods (animation). The use of geoinformation technologies to study biological diversity was included in the agenda of five conference sessions and later reflected in more than ten publications. They cover the development and creation of GIS, the use of geoinformation technologies for the analysis, assessment and mapping of biodiversity, for its monitoring and conservation. Quite a large number of articles are devoted to the study of forest resources. GIS technologies were used to solve problems of forest management, cartometric analysis of forested areas, determination of taxation indicators, systematization of forest conditions, etc. Examples of geoinformation versatile research for medicinal plant resources are given to assess their quality, resources and productivity in the region, to identify growing areas, including ones to be protected. Most of the published materials concerning to vegetation monitoring mainly relate to forests and forest management.

The distribution of the Sosnovsky hogweed on the southern border of the secondary range in the European part of Russia on the example of the Kursk Region is investigated in the work. It is revealed that Sosnovsky hogweed grows mainly in the western part of the Region in the vicinity of places where it was cultivated in fields in the second half of the twentieth century. The analysis of invader occurrence in anthropogenic and natural ecosystems of the Region revealed patterns of distribution that are characteristic of invasive species at initial stages of their secondary range formation: most of the foci are present in anthropogenic and semi-natural habitats; medium-sized foci predominate (from 100 sq. m. to 1 ha); the greatest number of foci was found in the areas located along roads. The intensive distribution of hogweed in settlements of the Region, especially with pronounced depopulation processes, was revealed. Among natural and semi-natural habitats, most of the foci were found along the banks of reservoirs. In forests, hogweed is found mainly in small groups of vegetative rosettes on the outskirts, with the exception of areas with a strong anthropogenic impact, where multiple foci with generative shoots are formed. At present, hogweed is not found on arable land due to the intensive cultivation of agricultural land in the Region. Plant communities with Heracleum sosnowskyi in the Kursk Region are represented by 4 syntaxons: association Urtico dioicae-Heracleetum sosnowskyi , association Rudbeckio laciniatae - Solidaginetum canadensis variant Heracleum sosnowskyi , association Chelidonio-Aceretum negundi variant Heracleum sosnowskyi , derivative community Heracleum sosnowskyi [ Agropyretalia intermedio-repentis ].

During the last few decades, there has been a growing realisation that biodiversity conservation cannot be successful without the active involvement of the people living close to and dependent on natural ecosystems for their survival and livelihoods. Consequently, there has been a gradual broadening of the global conservation agenda from strict nature protection to include the sustainable use of natural resources, which is now reflected in governmental policy the world over. However, as conservationists strive today towards the harmonisation of people's needs with biodiversity conservation, one of the most elusive, yet critical, goals for them has been the sustainable extraction of plant resources from the wild. Hundreds of plant species continue to be extracted from natural habitats for use as food, medicine, fuel and fodder in households and for commercial sale, both legally and illegally. As a consequence of unmonitored extraction and over-exploitation, many plant species populations are reported to be declining in the wild. In the face of increasing pressure on forest resources, it has become more important than ever before to devise quantitative management policies for sustainable plant use so that both forests and the livelihoods of millions of rural people who are dependent on them, can be sustained. One of the major stumbling blocks for conservationists in developing countries, who are attempting to design and implement sustainable forest management systems, is the lack of information on the state-of-the-art in this field, especially that relating to field methods, data analysis, data recording and monitoring systems. In order to fill this lacuna, a comprehensive bibliography of studies undertaken so far in the science of sustainable use from terrestrial ecosystems is presented here. The scope of this bibliography includes sustainable

Aquaculture is one of the most promising and dynamically developing types of agricultural production, especially in countries with warm climates. The research was carried out to analyze the current situation in aquaculture in Vietnam to clarify the existing problems and prospects of this industry. When collecting materials, we used statistical data from the Government of the Socialist Republic of Vietnam, as well as information from representatives of the Institute of Economics and Business of the Vietnam National University (Hanoi). In the Socialist Republic of Vietnam, aquaculture is well developed and continues to actively expand, annually increasing the production of products that are in significant demand on the world market. One of the most important problems of the industry is the threat to natural biodiversity, primarily due to the reduction of the natural habitats of the inhabitants of rivers and mangroves. An equally important problem is the strong dependence of the production of products, primarily shrimp, on foreign markets, which today is objective and insurmountable. Due to the use of chemicals and antibiotics in aquaculture, especially in natural conditions, environmental degradation is possible. Among the promising areas for the development of the industry is the convergence of natural ecosystems and agriculture, a good example of which is the cultivation of shrimp in mangroves without destroying the forest cover. It is possible to switch to aquaculture as an adaptation to changes in the ecological situation, primarily to the salinization of river deltas. As a result of a decrease in the profitability of fishing in the natural habitat of fish and shrimps, an increase in their populations in natural conditions is possible

Contextual Values

Values have a profound influence on the behaviour of all people, scientists included. Biodiversity is studied by ecologists, like myself, most of whom align with the “mission-driven” field of conservation biology. The mission involves the protection of biodiversity, and a set of contextual values including the beliefs that biological diversity and ecological complexity are good and have intrinsic value. This raises concerns that the scientific process might be influenced by biases toward outcomes that are aligned with these values. Retrospectively, I have identified such biases in my own work, resulting from an implicit assumption that organisms that are not dependent on natural habitats (e.g., forests) effectively do not count in biodiversity surveys. Finding that anthropogenic forest disturbance reduces the diversity of plant species dependent on shady forests can thus be falsely equated with more general biodiversity loss. Disturbance might actually increase overall plant diversity (i.e., including all of the species found growing in a particular place). In this paper I ask whether ecologists share values that are unrepresentative of broader society, I discuss examples of potential value-driven biases in biodiversity science, and I present some hypotheses from behavioral economics on possible psychological underpinnings of shared values and preferences among ecologists.

Impact On Biodiversity

The purpose of this study is to explore the biodiversity reporting practices inside Indian companies. Biodiversity reporting studies across Indian companies are important because India has a wealth of biodiversity assets, that is, wildlife, flora, fauna, natural habitats, rare and endangered species and biological resources, and accounts for 7.8% of the global recorded species (Biological Diversity Act, the Biodiversity Rules, Andhra Pradesh Biodiversity Board, 2009). There are approximately 45,500 species of plants, 91,200 species of animals and 5,550 microbial species documented in India (National Biodiversity Authority, 2014). The International Union for the Conservation of Nature (IUCN) has listed 132 species of animals and plants in the Critically Endangered Category (Sudhi, 2012). To date, the literature omits to explore the biodiversity reporting practices inside Indian companies. Another important reason to conduct is this study is that India has alarming population levels; thus there is a huge demand for land, energy, and resources, which leads to massive biodiversity loss, deforestation, and habitat destruction. It is very likely that with the limited land mass and increasing population in India, several ecosystems, wildlife, flora and fauna will be/have been exploited, disturbed, and endangered. Given the high potential impact on biodiversity by industries, we are concerned that there is a dearth of biodiversity reporting studies within the Indian subcontinent. We concentrate on the largest companies (based on market capitalisation) because similar to Van Liempd and Busch (2013), we also expect that the largest companies have the greatest impact on biodiversity; therefore, they are expected to show more accountability to their stakeholders. Therefore it is worth exploring how Indian companies are engaging in biodiversity reporting practices (e.g. biodiversity conservation, biodiversity protection, habitat and ecosystem conservation); and whether these organisations are disclosing their impact(s) (both in quantity and quality) on biodiversity (such as wildlife, flora and fauna). Moreover, India has also been classified as one of 17 mega-diversity countries by The World Conservation Monitoring Centre which account for more than 70% of the planet’s species (Williams, 2001). All these reasons make this study timely and important.

Ecosystems are critically important components of Earth’s biological diversity and as the natural capital that sustains human life and well-being. Yet all of the world’s ecosystems show hallmarks of human influence, and many are under acute risks of collapse, with consequences for habitats of species, genetic diversity, ecosystem services, sustainable development and human well-being. The IUCN Global Ecosystem Typology is a hierarchical classification system that, in its upper levels, defines ecosystems by their convergent ecological functions and, in its lower levels, distinguishes ecosystems with contrasting assemblages of species engaged in those functions. This report describes the three upper levels of the hierarchy, which provide a framework for understanding and comparing the key ecological traits of functionally different ecosystems and their drivers. An understanding of these traits and drivers is essential to support ecosystem management.

Many studies in recent years have investigated the effects of climate change on the future of biodiversity. In this chapter, the authors first examined the different possible effects of climate change that can operate at individual, population, species, community, ecosystem, notably showing that species can respond to climate challenges by shifting their climatic change. Climate change is one of the most important global environmental challenges that affect all the natural ecosystems of the world. Due to the fragile environment, mountain ecosystems are the most vulnerable to the impact of climate change. Climatic change will affect vegetation, humans, animals, and ecosystem that will impact on biodiversity. Mountains have been recognized as important ecosystems by the Convention on Biological Diversity. Climate change will not only threaten the biodiversity, but also affect the socio-economic condition of the indigenous people of the state. Various activities like habitat loss, deforestation, and exploitation amplify the impact of climate change on biodiversity.
