Složitý svět jedním číslem aneb Česko v indexech
Čermáková, Eva ; Grešlová, Petra ; Kochová, Tereza ; Mertl, Jan ; Pokorný, Jan ; Přech, Jiří ; Svirskyi, Volodymyr ; Vlčková, Václava ; Havránek, Miroslav ; Koblížková, Edita ; Hejná, Lenka
Publikace přináší přehled nejznámějších indexů, pomocí nichž hodnotí pokroky v nejrůznějších oblastech lidské činnosti ve světle dosahování udržitelnosti ve všech jejích pilířích – v environmentálním, sociálním i ekonomickém. Stav a vývoj v Česku je ukázán jednak pomocí skóre patnácti vybraných indexů a porovnáním s žádoucím stavem, tak i v rámci zemí Evropské unie a celého světa. Cílem knihy je najít odpovědi na otázky, jak Česko čelí komplexním výzvám nejen v oblasti životního prostředí, ale i v kontextu sociálně-ekonomickém. Jinými slovy, jaká je kvalita života či ekonomický vývoj, jelikož lidská společnost, její ekonomika a přírodní sféra fungují jako ucelený a propojený systém vzájemných interakcí. Jako nástroj pro mapování situace využívá hodnocení pomocí indexů, protože je u nich výrazná snaha o komplexní propojení nejrůznějších témat, která spolu zdánlivě nesouvisí, ve skutečnosti se však navzájem výrazně ovlivňují. Pořadí Česka se v mezinárodním srovnání u jednotlivých indexů liší v závislosti na zvoleném tématu, metodě výpočtu a vstupních datech. Jejich pochopení napomáhá uvedení silných a slabých stránek indexu a popisu, jak jsou jednotlivé indexy konstruovány – které indikátory a vstupní data do jejich výpočtu vstupují i popis metodiky výpočtu.

Impacts of directive 2019/904/EU on the management of plastic beverage bottles of up to 3 litres in the Czech Republic
Martiniaková, Ivana ; Král, Jakub
The article focuses on the impacts of Directive 2019/904/EU on the management of plastic beverage bottles with a volume of up to three liters. It describes how various European countries and the Czech Republic deal with loading and negative effects, describes three main collection methods which are distinguished in European countries and discusses whether to maintain the existing collection system or whether it would be better to introduce a back-up system to achieve the value of sorted collection at 77% by 2025.

Distribution of the Contaminated Sites on the Territory of the Czech Republic
Suchánek, Zdeněk
The National Inventory of Contaminated Sites (NIKM 2 project) was completed in December 2021. We present the output regarding the distribution of inventoried, contaminated and potentially contaminated sites (CSs) in 205 administrative districts - Municipalities with Extended Powers ("small districts"). The filled database of the Contaminated Sites Registration System (SEKM) [1] serves as the main source for the so-called Planning Analytical Materials, i.e., for spatial planning at the level of Municipalities with Extended Powers. Until now, incomplete documents on CSs were used. After the completion of the inventory, the updates of the territorial analytical documents in this matter can be based on relevant data.

The Inventory of Contaminated Sites in the Czech republic (NIKM 2019–2021)
Suchánek, Zdeněk
The complete National inventory of contaminated sites (NIKM) took place in the years 2009 – 2021 in two phases, both co-financed from the EU Cohesion fund. The basic goal of NIKM was the capture and basic evaluation of the most complete number of contaminated sites/potentially contaminated sites (CSs hereinafter) on the territory of the entire country. The 1st stage of NIKM focused on the methodology of the inventory, its testing and collection of the main data sources. The 2nd stage of NIKM (2018-2021) was completed on 31.12.2021. CENIA teams and suppliers selected via public tender participated in the project. 30,020 CSs or CSs clues were inspected of which 8,643 sites were evaluated as CSs. From other sources, 1491 newly evaluated localities were registered. In result, a total of 10,134 assessed CSs were registered. These sites have a record at least in the scope of the summary form, including the evaluated priority of needed corrective measures. In addition, maps of CSs distributions in the 205 municipalities with extended powers (“small districts”) of 14 regions were processed, for each of the three priority categories (A, P, N). The result of NIKM is the filled in System for registration of contaminated sites (SEKM) (10,134 records), 14 inventory reports for individual regions and the Inventory Report for the Czech Republic.

Spectral Indices as a Tool for Hop Growth Evaluation
Seidlová, Jana ; Procházka, Pavel ; Kumhálová, Jitka
The use of unmanned aerial vehicles (UAV) to monitor crop growth is nowadays a common non-invasive way how to obtain information on the current state of crops. Spectral indices derived from multispectral images obtained in the right growth stage can then serve as a good data source for agro-technical interventions and yield estimation. Hop belongs among the crops where it is possible to scan the individual growth parameters very exactly. In the year 2021, significant precipitation amounts were recorded during the growing season, when it turned out that UAVs are a very powerful tool for determining the quality of production or quantification of vegetation damage compared to the previous year (2020). It was found that the common spectral indices were possible to use for calculation leaf area, structure, vigor and chlorophyll content of hop gardens.
