The biodiversity footprint of consumption in the Czech Republic
Matuštík, Jan ; Vačkářová, Davina Elena (advisor) ; Weinzettel, Jan (referee)
The exponential increase in the scale of human influence on Earth, especially in the past century, has now led to a crisis of biodiversity. Most direct drivers of the biodiversity crisis are present at local scales - local ecosystems are destroyed by a land use change, local populations are annihilated by overhunting. Nevertheless, in the globalized world, our actions do not only affect the ecosystems directly around us but also those located on the other side of the globe. Next to the direct impacts we pose on the ecosystems we live in, we are also partly responsible for the indirect, tele-coupled impacts we pose on distant ecosystems. The goal of this study is to map the impacts consumers in the Czech Republic cause to ecosystems in other countries. Environmental footprints, and specifically biodiversity footprint, are the tools commonly used to measure such distant environmental impacts and to allocate responsibility for them to the final consumers. There are currently multiple methodologies to quantify biodiversity footprint which are, nevertheless, burdened by some methodological problems or do not properly fit the goal of this study. Therefore, a novel method was developed here employing the Biodiversity Intactness Index as the measure of the state of ecosystems. This biodiversity footprint,...

TITLE: Evaluation of ecosystem integrity and services on regional level with the use of participatory approaches AUTHOR: Mgr. Jakub Zelený DEPARTMENT: Environmental studies SUPERVISOR: Mgr. Davina Elena Vačkářová, Ph.D. ABSTRACT: The presented work proposes and applies a set of methods designed to describe ecosystem integrity, services and landscape values, including their interaction, on the example of several studied regions. The included publications describes 4 types of methods for evaluating these phenomena: remote sensing of the Earth, regional statistics, expert matrices, and qualitative interviews and mapping. Applied methods can be divided into natural sciences and social sciences, and part of the work is to evaluate the benefits and compare the compatibility between these very different methods in evaluating selected elements of landscapes. The methods are applied in a variety of ranges, ranging from urban areas (10 km2) to the federal states. Natural ecosystems and forests have been assessed best in terms of ecosystem integrity, with the relationship between ecosystem integrity and crop production being negative. Qualitative mapping of landscape values revealed that pristine and inaccessible areas, as well as single- purpose sites, had low societal value in terms of intensity and / or diversity...
Assesing the complience of nature conservation in the Czech republic with international strategic objectives
Daněk, Jan ; Vačkářová, Davina Elena (advisor) ; Kružíková, Eva (referee)
The subject of the master thesis is the assessment of the compliance of nature conservation in the Czech Republic with international strategic objectives, analysing the mainstreaming of biodiversity across government and society and analysing the fulfilment of the commitments rising for the Czech Republic as a member of the Convention on Biological Diversity (CBD). The thesis is focused on an assessment of strategic goal A of the Strategic Plan for Biodiversity 2011-2020 and its 4 Aichi targets related to the mainstreaming of biodiversity and ecosystem services in society and policy. The methodology used is a systematic search of available relevant documents and other related sources, especially the national reports from the Ministry of the Environment to the Secretariat of the Convention on Biological Diversity and other associated analysis and reports. Another aim of the thesis is summarizing the current state of the mainstreaming of biodiversity to governance and decision making and identifying the areas which are not included in the national strategic documents or are not included sufficiently. In addition to the theoretical analysis, the thesis suggests specific actions and indicators for reaching the targets included in the international strategic documents, particularly the Strategic plan of...
Perception of climate change impacts and adaptive capacity in organic agriculture
Říhová, Jana ; Vačkářová, Davina Elena (advisor) ; Pražan, Jaroslav (referee)
This thesis deals with the perception of climate change issue and adaptive capacity of organic farming systems in the Czech Republic. The aim of this thesis it to investigate organic farmers' attitudes toward climate change and their willingness to adopt adaptation practices. The method used in this thesis is based on questionnaires that were distributed among organic farmers in the period of January-March 2015; 52 questionnaires were subsequently analysed. The results indicate that the majority of organic farmers surveyed believed that the global climate change is occurring, expected negative climate change effects and observed higher frequency of extreme weather events. Most of the respondents also acknowledge the importance of adaptation practices and their own responsibility in adaptation. The statistical analysis revealed that both the belief about climate change and perception of associated threats may serve as predictors of the willingness to implement adaptation measures.
Assessment of climate change impacts on selected ecosystem services in the Czech Republic: application of land use scenarios
Lorencová, Eliška ; Vačkářová, Davina Elena (advisor) ; Müller, Karel (referee) ; Cudlín, Pavel (referee)
Doctoral thesis abstract Assessment of climate change impacts on selected ecosystem services in the Czech Republic: Application of land use scenarios MSc Eliška Lorencová Climate and land use change are recognized as the greatest global environmental problems. Both considerably impact delivery of crucial ecosystem services, such as carbon sequestration, water flow regulation, erosion control, and food and fibre production. By combining future projections of ALARM scenarios (for years 2020, 2050 and 2080) with modelling of ecosystem services, the study aims to evaluate climate change impact on selected ecosystem services (carbon storage and sequestration, erosion control and sediment retention) in the Czech Republic. This study provides quantitative as well as spatially explicit analysis of the impacts on selected ecosystem services in the Czech Republic. Performed ecosystem service assessment indicates that spatial distribution of provision of ecosystem services, such as carbon storage and sequestration, sediment retention reflects the projected future land use changes. In case of carbon sequestration, SEDG scenario shows the lowest carbon sequestration rates accounting for 37,029.6 Gg C within the period 2000-2080. Stable vegetation cover is one of the factors that play important role in amount of sediment...
Assessing ecosystem services and the alternatives of their future development in UNESCO Biosphere Reserves
Harmáčková, Veronika Zuzana ; Vačkářová, Davina Elena (advisor) ; Cudlínová, Eva (referee) ; Pechanec, Vilém (referee)
The provision of ecosystem services within social-ecological systems is influenced by multiple environmental and anthropogenic driving forces, affecting natural ecosystems. At the same time, the capacity of ecosystems to concurrently provide different types of ecosystem services is inherently limited. Thus, ecosystem changes and their effect on ecosystem services have direct implications for human existence and well-being. The aim of this thesis is to present a modelling approach to assess regulating, provisioning and cultural ecosystem services and to quantify their potential trade-offs, illustrated by two case studies carried out in selected UNESCO Biosphere Reserves in the Czech Republic, Třeboň Basin Biosphere Reserve and Šumava Biosphere Reserve. Both of the selected case study areas are characterized by high levels of natural and cultural assets and challenges regarding future landscape management. In this study, first the social-ecological dynamics within the study areas was analysed by creating participative scenarios through collaboration with local stakeholders, eliciting their preferences regarding future landscape development to 2050. Second, the impact of the scenarios on ecosystem services and their trade-offs were assessed using a combination of spatially explicit models and...
Defining the Basic Socio-ecological Landscapes Types in the Czech Republic in the Context of Ecosystem Service Provision
Spustová, Kateřina ; Vačkářová, Davina Elena (advisor) ; Romportl, Dušan (referee)
Current approaches of anthropogenic impact on the ecosystems and ecosystem services are within the scope of this master's thesis. The aim of the thesis is, on the basis of current landscape classifications, landscape typologies, and their combination with approaches of ecosystem services classification, to appoint socio-ecological units as functional socio-ecological types of the territory. In other words, on the basis of classification listed, this thesis attempts to prove, that socio-ecological units are functional socio-ecological types of the territory, which should be given proper attention. Socio-ecological landscapes are defined according to degree of anthropogenic impact, selected socioeconomic characteristics, and selected ecosystem services. The thesis focuses on three of four categories of ecosystem services defined in Millennium Ecosystem Assessment - provisioning services, regulating services, and cultural services. As a methodology, the quantitative research was chosen. The research was carried out by data collection and the analysis of statistical data of Czech Statistical Office, Czech Office for Surveying, Mapping and Cadastre, and Statistical Yearbook of Soil Services. The thesis main finding is that social and ecological components of socio-ecological systems are in mutual...

The Application of the National Footprint Accounts for agricultural production based on national data
Corlannová, Lenka ; Vačkářová, Davina Elena (advisor) ; Třebický, Viktor (referee)
The aim of this thesis is to compare the National Footprint Accounts of the Czech Republic in the section of cropland and grazing land for the year 2007 based on globally available data and data available in the Czech Republic, and also to compare these National Footprint Accounts of the Czech Republic based on nationally available data from the years 2007 and 2013. This thesis used the method of calculation of the National Footprint Accounts developed by Global Footprint Network. The ecological footprint of cropland of the Czech Republic is lower according to national data compared to global data while the ecological footprint of grazing land is higher. According to national data, the ecological footprint of both cropland and grazing land of the Czech Republic was lower in 2013 compared to 2007. This work gives an opportunity to compare the calculation of the ecological footprint and biocapacity of cropland and grazing land based on different data sources and to compare the results based on data from 2007 and 2013.
