- ItemDelays in territorial development – case study of the Hungarian Sand Ridge Region(2023) Kovács, András Donát; Farkas, Jenő Zsolt; Varjú, Viktor; Szalai, Ádám; Hoyk, Edit; Lennert, József; Csáki, BélaThere are regions in Europe that are particularly vulnerable both environmentally and socially. Hungary's Sand Ridge in the Danube–Tisza Interfluve (Homokhátság in Hungarian) is considered such a region. The water balance of these lowland landscapes has been negative for decades, and complex ecological and social problems have escalated in parallel with aridification. Therefore, this region deserves special attention from the territorial development perspective. Over the last two decades, our successive studies have revealed that development policies in the region have been unsuccessful on multiple occasions, unable to alter the core negative trends significantly. We also noticed the mistakes and inertness of spatial planning when we worked on our current applied research: the Sand Ridge Regional Development Concept and Program. This study aims to explore deficiencies and shortcomings of the spatial policy and identify the factors that have slowed territorial development. Insights from interviews with experts and surveys conducted with local municipalities highlight that access to European Union funds has not alleviated long-standing conflicts. Resource-driven and uniform planning has become one of the main hindering factors. According to the experts, the necessary complex programs have not been implemented, and many initiatives have stalled. They also expressed concerns that Sand Ridge's natural and social endangerment will continue to increase.

- ItemHomokhátság - a special rural area affected by aridification in the Carpathian basin, Hungary(2017) Farkas, Jenő Zsolt; Kovács, András Donát; Hoyk, EditIn Hungary, the aridification primarily affects the Great Hungarian Plain, most specifically the “Homokhátság” area which is part of the Danube-Tisza Interfluve. On the basis of our experience gained in the past 15 years, we would like to give an insight into the complex problems of this rural region. Our starting point is the aridification process and water scarcity which are characteristic features of this area for the last century. We investigate the related problems in land use management such as unfavourable land use and vegetation changes and the challenges in the local economy and social sustainability. In this respect we introduce the emerging issues in agriculture, forestry and nature conservation which may be relevant in European context too. We have discovered specific factors related to the devaluation of the rural environment and found that significant part of the unfavourable phenomena can be explained by the combined effect of climatic changes, improper land use and inappropriate environmental management. Based on our findings we outline a possible regional pathway for a sustainable rural development.
- ItemInvestigation of ground and artesian waters as irrigation water on the Great Hungarian Plain(2015) Hoyk, Edit; Pető, Judit; Hüvely, AttilaOne of the most significant attribute of soils is that they function as water reservoirs. Subsurface waters — used as irrigation water — can contribute to nutrient supply, but their pollution has a negative impact on the conditions of cultivation. In our study we present the results of our investigation of ground and artesian water samples from the Great Hungarian Plain, mostly from Kecskemét and its surroundings. Based on the depth of the sampling points, we divided the samples into three categories: between 10-30, 31-70 and 71-275 meters. The results showed that the salt content is decreasing with the deepness, primarily because of the decrease in sodium, hydro-carbonate and chloride contents in the samples. The level of nitrogen and phosphorous-ions were low in almost all water samples. Iron, manganese and arsenic content were the highest in the middle deep waters (31-70 m depth). These results — especially in the case of iron and arsenic — can cause problems in the use of these waters in agriculture for cultivation and irrigation. Nowadays decreasing groundwater stocks decrease the water sources of irrigation. Nevertheless usage of subsurface waters for irrigation is important in the future, for example about their function as a potential nutrient sources. Their sensitivity against pollutions draw attention to the essential task of continuous quality parameters monitoring of subsurface waters.
