Adaptation to climate change with green infrastructure in urban environmen = A városi zöld infrastruktúra vizsgálata a klímaváltozással szembeni adaptációkban
(2018) Hoyk, Edit
A klímaváltozás negatív hatásaival szembeni adaptáció városi környezetben elsősorban a túlzott felmelegedés elleni védekezésre, ill. a városi hősziget-hatás mérséklésére fókuszál. Ebben a folyamatban a zöld infrastruktúrának kitüntetett szerepe van, és kell, hogy legyen a jövőben is. Jelen tanulmányban egy magyarországi középváros, Kecskemét példáján mutatjuk be a városon belüli mikroklimatikus eltéréseket, amelyek utalnak a városi hősziget kialakulására. Mennyiségi és minőségi szempontból elemezzük a belváros zöldfelületeit, amelyek szerepet játszhatnak a hősziget-hatás csökkentésében, valamint kitérünk a túlmelegedéssel szembeni egyéb adaptációs lehetőségekre, mint pl. zöld falak és homlokzatok, zöld tetők, reflektív tetők és járdák, stb. Következtetésként javaslatokat fogalmazunk meg az egyes, zöld infrastruktúrához kötődő adaptációs eszközök alkalmazási lehetőségeivel kapcsolatban, amelyek egy kontinentális klímájú, közép-kelet európai középváros esetében hatékonyan szolgálhatják a klímaváltozás negatív hatásainak mérséklését.
Climate consciousness and adaptation from the viewpoint of farmers
(2017) Farkas, Jenő Zsolt; Hoyk, Edit
Adaptation to climate change and finding solutions to the environmental consequences are urgent tasks. The role of farmers in the adaptation is essential, that is why beliefs of farmers in this theme are important. In our work we give an overview about the opinion, knowledge and attitude of farmers in relation to climate change. We revealed their knowledge and individual insights with questionnaires. 50 farmers from the area of Kiskunság participated in it. Our aim with the questionnaire was to assess the farming community’s information about the climate change, explore the changes in their natural environment and actions against unfavourable trends. In addition, we tried to get answers about what kind of assistance the producers require to overcome these problems in the future. Beside the questionnaire we interviewed large agricultural entrepreneurs, agricultural public administration employees and agricultural intellectuals about the effects of climate change in the agriculture. We found that farmers are mostly waiting for outside help for resolving their problems, in the form of financial support and a solution for the problem of irrigation. It is highlighted that up-to-date knowledge and flexibility are needed in order to prevent damages. It means adequate production technology and farming practices instead of only increasing the monetary aid.
Climate vulnerability regarding heat waves – a case study in Hungary
(2018) Uzzoli, Annamária; Szilágyi, Dániel; Bán, Attila
One form of climate change vulnerability is the increase in the number, frequency and length of heat waves related to temperature rise. The protection against the health and sanitary risks of heat waves will pose a major challenge at national, regional, as well as local level in the future. The aim of the study is to present the main results of an assessment of climate change vulnerability conducted in a research project. Through statistical analyses, vulnerability was calculated based on the exposure, sensitivity and adaptive capacity at district level (LAU1), which is a complex information carrier about the vulnerability of population and institutions to heat waves. The territorial differences of vulnerability proved the West-East division of the country, but the centre-periphery relation also plays role in the development of territorial pattern. Based on statistical examinations it is ascertainable, that, in total, 42.5% of the country’s territory, where currently 39.5% of the population live, is severe and extreme vulnerable to the effects of climate change. The main results of the research can also be used as suggestions for the local decision-making related to the preparation for and adaptation to the health effects and sanitary consequences of heat waves.
Cosmopolitans in a farmhouse: Return migration and the adaptation of habitus through the lens of a homemaking process
(2022) Németh, Krisztina
This paper is an attempt to offer a specific perspective on the interrelation and complexity of the spatial and social mobility trajectory and its multi-layered effects on habitus. This family case study is based on two semi-structured family history interviews. Its protagonist is a return migrant who is deeply embedded in the periphery (tanyavilág) of a Hungarian rural town. After spending almost fifteen years in the UK, she moved back to this relatively marginalised micro-place and bought an old farmhouse. The interpretation of her periodical migration trajectory focuses on the process of change in habitus and interprets the question of the ‘emotional cost’ of migration through the interrelation of spatial and social mobility. This perspective emphasises the spatial aspects of how mobility can dynamize the practical and emotional aspects of dislocation and belonging, while offering an insight into the adaptation of habitus. It is primarily examined through a homemaking process, which reveals the reconciliation of different place-based, family-inherited, and newly developed (migration-related) dispositions. This Bourdieusian interpretation shows that this home is a materialised reality as well as a symbol of social and spatial position. This harmonious ‘sense of (social) place’ (Hillier & Rocksby, 2002) can be grasped in terms of taste and lifestyle, revealing that ‘freedom of choice’ is the lived meaning of this intergenerational social mobility trajectory, which was fuelled by transnational migration.
Geographical analysis of climate vulnerability at a regional scale: the case of the Southern Great Plain in Hungary
(2017) Farkas, Jenő Zsolt; Hoyk, Edit; Rakonczai, János
This paper provides an example for regional scale analysis of climate vulnerability incorporating environmental as well as socio-economic indicators. Researches have focused on different aspects of climate vulnerability so far, but usually there is little connection between the physical and social dimensions. Our study provides a more complex analysis, which builds on the application of international indices which have been used on the local and regional levels very rarely. In our research we combined physical and human geographical approaches and research techniques. The physical geographical assessment is based on indicators referring to ground water levels and vegetation production, while the human geographical side of the analysis focuses on economic and social sensitivity, adaptation and exposure indices, combined in the so-called socio-economic climate vulnerability index. In the analysis we tried to figure out the most sensitive areas in the Hungarian Southern Great Plain region. The main findings of the study are „hot spots” which coincide on both analyses, therefore, the most sensitive areas under current climate change conditions could be delimited. This study also demonstrates that the resolution of global climate change vulnerability indices is not suitable for regional scale analysis because of the significant territorial differences. Therefore, local or regional scale assessments are needed for the preparation of strategies for the elaboration of mitigation and adaptation policies.
Investigation of soil permeability and suitable vegetation for rain gardens in Kecskemét
(2021) Hoyk, Edit
Nowadays, the implementation of integrated stormwater management is an important element of urban climate adaptation. Rain gardens are part of this system, which effectively handles large amounts of sudden precipitation. In this way, they are suitable for preventing the increasing frequency of flash floods. For rain gardens, it is important to collect information about the soil and the vegetation. We examined the permeability of the typical soil types in Kecskemét – humus sandy soil, solonetz meadow soil – and Bácsvíz compost, in order to decide what proportion of soils and compost can be considered ideal for rain gardens. In addition, experiments were performed with three broad-tolerant plants (Inula Britannica, Aster tripolium subsp. pannonicus and Limonium gmelinii) planted in the studied soil types and compost, as well as in a mixture of these. Based on our results, it can be concluded that the solonetz meadow soil practically means a waterproof layer, while a mixture of half of this soil type and compost already has adequate water permeability and water storage properties, which provide the necessary living conditions for plants.
The role of climate strategies and green infrastructure in the adaptation to climate change
(2017) Hoyk, Edit; Kovács, András Donát
Climate change is one of the greatest challenge for the economy, society and settlements. Today it is an expectation to mitigate the expected negative consequences and to make adaptation efforts. To achieve this, municipal climate strategies are needed which must include successfully used possibilities in adaptation. In our paper, we overview the specialities of the current Hungarian climate strategies, expectations for the future climate strategies and the role of green infrastructure as a possible method for adaptation. We investigated the climate strategies, and also conducted additional experts’ interviews. To confirm the effectiveness of green infrastructure, we analysed the inside and outside temperatures in a green-walled building for a two-month period. As a result of the analysis and the comparison of Hungarian and international climate strategies, we can conclude that these documents put great emphasis on the use of renewable energy sources. Our suggestion is that the application of energy-saving green walls should get a greater role among adaptation possibilities in the future. First results of our measurement show that in the case of green-walled buildings the difference in the temperature between walls with and without shadow can reach 20 °C, and shading can reduce indoor minimum temperature with 4-5 °C. Besides that, application of green walls has a great importance from the perspective of reducing CO2 emission, and improving of air quality thanks to the O2 production.
Tasks and suggestions for the adaptation to the climate change in Kecskemét
(2020) Hoyk, Edit
Adapting to the expected negative impacts of climate change in our region is a strategic task in order to preserve the ecological conditions of the region and ensure the conditions for sustainable development. Responsible management of local water resources is essential (rainwater and purified sewage, saving water use) together with water supply, rational land-use change, deliberate management of green spaces, and eco-friendly urban planning/design. These serve both to preserve the natural features of the area, to ensure the sustainable use of landscape resources and to ensure the long-term viability and operability of the city.
Transferring circular economy solutions across differentiated territories: Understanding and overcoming the barriers for knowlege transfer
(2019) Varjú, Viktor; Dabrowski, Marcin; Amenta, Libera
“Learning from abroad” is a widely recognised and used means to innovate and improve strategies and policies implemented by regions and cities. However, literature on knowledge transfer and related concepts, such as policy transfer, policy mobility or lesson-drawing, highlights the limitations of this process, especially when it entails the simple transfer of (best) practices from “place A” to “place B”. Such a transfer may lead to suboptimal solutions particularly when the imported practices concern complex phenomena, involving networks of multiple actors and relying on place-specific dynamics. Departing from this critique, the article sheds light on the process of knowledge transfer in the field of circular economy, taking place between the two metropolitan regions of Amsterdam and Naples. This process is guided by an innovative methodology based on a network of (peri-urban) living labs generating eco-innovative solutions for using material waste and wastescapes as a resource in peri-urban areas. Using participant observation in knowledge transfer workshops, stakeholder interviews and surveys, it investigates how the process of co-creation of knowledge in the relational space of the networked living labs takes place thanks to the participation of stakeholders from both regions. This in turn allows for drawing conclusions on what barriers are encountered in such knowledge transfer, what makes solutions transferable across different contexts, and, finally, how the solutions are adapted as they travel from one place to another.
