Systematická rešerše o změnách využití půdy ke snižování rizik povodní a sucha a motivacích uživatelů půdy tyto změny provádět.

Abstrakt: Modifications to land can serve to jointly reduce risks of floods and droughts to people and to ecosystems. Whether land modifications are implemented will depend on the willingness and ability of a diversity of actors. This article reviews the state of knowledge on land modification use in areas exposed to dual hydrologic risks and the land owners, managers, and users who directly make decisions about action on lands they control. The review presents a typology of land modifications and explains how land modifications interact with the hydrological cycle to reduce risks. It then addresses the roles and perspectives of the land owners, managers, and users undertaking land modifications, summarizing theories explaining motivations for, as well as barriers to and enablers of, land modification implementation. The analysis reveals geographical differences in narratives on land modifications as well as knowledge gaps regarding variation across actors and types of land modifications.

Článek se věnuje přínosu carsharingu k proenvironmentálnímu chování – porovnává uživatele carsharingu, kteří mají k dispozici vlastní automobil, a těch bez něj.

Abstrakt: This paper provides insights into differences in carsharing users‘ attitudes, motives for joining carsharing, and transport behaviour between users with and without another car at their disposal. It builds on revealed and stated data about members of the oldest carsharing company in the Czech Republic. Carsharing adopters without a car utilise shared cars more intensively than carsharing users with a car available in their household. On the other hand, unlike the second group, they drive fewer kilometres by car in total. The car availability in households also influences the shift in car use after joining carsharing. The sale of a car thanks to adopting carsharing is a factor leading to a decrease in overall car use. Those who have a car at their disposal within their household have a lower probability of decreasing kilometres driven after joining carsharing. Households without an additional car available seem to be less car-dependent on average than those utilising carsharing as a second or third car. They tend to be more environmentally conscious and more inclined towards policies supporting alternative modes and restricting private car use, although both groups share these beliefs. The findings open a debate over whether carsharing increases the legitimacy of restrictive transport measures against private car ownership and use.

Článek zjišťuje, jaké byly dopady pandemie covid-19 na dojíždění do práce a práci z domu a zda se dopady lišily mezi ČR a Izraelí.

Abstrakt: The COVID-19 crisis has forced many people to work from home, rather than at their regular workplace. This paper aims to assess the impact of the pandemic on telecommuting and commuting behavior after the end of the crisis: Will people embrace teleworking and reduce commuting, even to some extent, or will they resume their pre-pandemic work patterns? This study, implementing a cross-country survey from Israel and Czechia, combines data regarding revealed preferences about work habits before and during the pandemic and stated intentions data regarding anticipated work patterns when life returns to „normal“ after the pandemic. Two models were used for the data analysis, one addressing factors that affect the increased/decreased teleworking trend and the other addressing factors that affect the frequency of actual commutes. The results reveal that most respondents (62% in Israel and 68% in Czechia) will maintain the same telecommuting/working from home balance. About 19% of respondents in both countries expressed their intention to reduce the number of commuting days, while 6% stated they would increase out-of-home days. However, these estimates rely only on workers‘ expectations not accounting for employers‘ point of view and other constraints they may have. Not accounting for potential bias, a moderate reduction of 6.5% and 8.7% (in Israel and in Czechia, respectively) in the number of commuting trips is expected in the post-pandemic era. The anticipated decrease in commuting days is accompanied by an increase in teleworking: from 10% to 14% among those who work more than 20 h a week (in both countries) and a drop in the rate of those who telework five hours or less a week (down from 73% to 63% in Israel and from 76% to 70% in Czechia). Self-employment, travel time to work, working solely on premise during the lockdown, and personal preferences regarding telework versus working away from home were found to significantly contribute to a decrease in the number of commuting days and to an increase in teleworking. An interesting finding is the high probability of increased teleworking among people who teleworked for the first time during the lockdown or who increased their teleworking time during the lockdown. This indicates that the teleworking experience due to the pandemic has enabled some people to view working from home as viable. Although, overall, the change in working habits does not seem dramatic, our results suggest that hybrid schemes for combining on premise and telework are expected to be adopted by some sectors.

Tento článek provádí rešerši 153 vědeckých publikací, zkoumající ekosystémové služby poskytované přírodě blízkými opatřeními z pohledu preferencí jednotlivců, komunit a společnosti.

Abstrakt: Ecosystem services (ES) provided by nature-based solutions (NBS) have been examined using various data collection techniques and preference elicitation methods to understand what ES are important to human well-being. This article provides a systematic review of 153 scientific publications, with a focus on data collection techniques and perspectives of well-being used when eliciting preferences toward multiple ES provided by NBS. ES provided by urban parks, urban trees, and community gardens are the most commonly examined; however, generally specified NBS such as “green spaces” or “green infrastructure” prevail. The review further shows that the questionnaire surveys is the dominant technique for bringing evidence about the most preferred ES, followed by semi-structured interviews and workshops. Only a limited number of studies use revealed or stated preference methods as a part of data collection efforts such as a choice experiment or contingent valuation. Additionally, the review defines three different perspectives of well-being considered but rarely discussed in existing studies: individual; community; and society well-being perspectives. As the concept of well-being is hardly discussed in NBS literature and still depends on a large degree of subjectivity, this review highlights the need for future research that looks more deeply at individual, community, and social well-being, which is influenced differently by the implementation of NBS.

Článek představuje ekonomické hodnocení dopadů nově stanovených emisních limitů pro velká spalovací zařízení

Článek představuje ekonomické hodnocení dopadů nově stanovených emisních limitů pro velká spalovací zařízení na české elektrárny. Na základě detailních dat a mikroekonomického přístupu je ilustrováno, že Evropská komise nejen významně podcenila ekonomické náklady spojené s dosahováním nových emisních limitů, ale stanovila emisní limity takovým způsobem, že jednotkové náklady plnění nové regulace jsou v porovnání s plněním předchozí regulace řádově vyšší. Dosažení nových emisních limitů totiž v drtivé většině případů vyžaduje pořízení nové technologie na snižování emisí (a tedy narušení inovačního cyklu), jejichž plný potenciál ovšem zůstane nevyužitý. Významná investice má proto pouze omezený environmentální dopad, což má za následek velmi vysoké jednotkové náklady na zachytávání polutantů. Regulace je tedy nastavena nevhodně a není v souladu s principem přiměřenosti, který je v evropské environmentální legislativě uplatňován. Buď mělo být spalovacím zařízením dovoleno pokračovat se stávajícími technologiemi za cenu nepatrně vyšších environmentálních dopadů, nebo měla být regulace přísnější a ospravedlnit masivní investice výrazným přínosem pro životní prostředí. Výjimky z plnění emisních limitů, o které elektrárny z důvodu nepřiměřených nákladů žádají, navíc celkový environmentální dopad ještě snižují.

Článek přibližuje, jak je možné využít CBA jako podpůrný nástroj při hledání kompromisů v rámci regenerace měst a povodňového managementu.

 Urban areas are hot spots of flood risk due to how urban development concentrates people and assets into hazard prone areas, reinforcing negative externalities on the welfare of urban residents. Mitigating flood risk in urban environments, however, is challenging. This is not only because the process generating flood risk is complex, but the objectives of city planners, residents and/or developers are also multi-faceted. Therefore, there are various trade-offs to be considered. One such problem across many areas of Europe and beyond is how to regenerate declined urban areas, to improve the welfare, prosperity, and image of the city. However, in turn, many areas within these cities will see this activity being traded-off against increased flood risk. Cost-benefit analysis represents a useful approach for assessing this trade-off, as a decision-support tool. In this paper we present an exploratory cost-benefit analysis of a potential urban regeneration project within the city of Ústí nad Labem (Czechia) that seeks to highlight the potential magnitude of such trade-offs that need to be more often actively considered as a core, rather than peripheral, element of urban regeneration. We present an exploratory framework that can be expanded upon and integrated into wider regeneration visions.
