“…Inorganic carbonates are found in medium amounts (3.5–4.5%). Soil fertility and the choice of agricultural crops are first of all limited by the low soil moisture content, as well as its extreme seasonal distribution and the low water retention capacity of the topsoil [ 35 , 36 , 37 ]. Frequent desiccation exposes the soil to sandstorms, which carry away large amounts of low-density humus particles.…”

Soil moisture reserves are a key factor in maintaining soil fertility and all other related ecosystem services (including carbon sequestration, soil biodiversity, and soil erosion control). In semiarid blown-sand areas under aridification, water preservation is a particularly crucial task for agriculture. The international Diverfarming project (2017–2022), within the EU Horizon 2020 Program, focused on the impacts of crop diversification and low-input practices in all pedoclimatic regions of Europe. In this three-year experiment conducted in the Pannonian region, the impact of intercropping asparagus with different herbs on some provisioning and regulating ecosystem services was evaluated in the Kiskunság sand regions. Relying on findings based on a range of measured physical and chemical soil parameters and on crop yields and qualitative properties, advice was formulated for farmers. The message drawn from the experiment is somewhat ambiguous. The local farmers agree that crop diversification improves soil quality, but deny that it would directly influence farm competitiveness, which primarily depends on cultivation costs (such as fertilization, plant protection, and labour). Further analyses are needed to prove the long-term benefits of diversification through enriching soil microbial life and through the possible reduction of fertilizer use, while water demand is kept at a low level and the same crop-quality is ensured.

“…A mezőgazdasági művelés számára rendkívül kedvezőtlen környezeti tulajdonságokkal rendelkezik (ZentAy T. 1989): a homokfrakció aránya 90-99%, minimális az agyagtartalma (0-0,3%), a talaj szegény szerves anyagban (összes széntartalom 1,5-3,5 g/kg), ezért alacsony szintű az aggregátumok képződése (a >250 μm átmérőjű szemcsék gyakorlatilag hiányoznak), közepes a szervetlen karbonátok mennyisége (3,5-4,5%). Elsősorban a csekély mennyiségű és szélsőséges évszakos eloszlású talajnedvesség, valamint az erősen limitált vízmegtartó képesség korlátozza a termékenységét és a termeszthető növények körét (Cserni I. et al 2015). A gyakori kiszáradás miatt a talaj nagymértékben ki vannak téve a széleróziónak.…”

The destructive environmental impacts of large-scale agriculture are further aggravated by drier climate in the Danube-Tisza sand region, where soil fertility is low, water retention is very limited and groundwater levels are steadily dropping. The prevention of wind erosion is a central task in raising the level of ecosystem services. Among other related services the enrichment of the blown-sand soil with organic matter (enhancing carbon sequestration), the improvement of soil structure and water retention capacity and achieving higher soil biodiversity are major objectives. The international Diverfarming project (2017–2022) within the EU Horizon 2020 Program focussed on the impacts of crop diversification and low-input practices. In the experiments intercropping with different annual crops was investigated and its influences on some provisioning and regulating ecosystem services were evaluated in an asparagus field in Jakabszállás. Although the findings point out the decisive role of soil moisture conditions, the positive impacts of diversification are also remarkable. The local farmer agrees that crop diversification improves soil quality, but he denies that it would directly influence farm competitiveness, which is primarily dependent on the costs of fertilization, plant protection and labour. Further analyses are needed to prove the benefits of diversification through enriching soil microbial life and the possible reduction of fertilizer use while water demand is kept at a low level and the same crop quality is ensured.

“…Hungary is also in a challenging position (Tran et al, 2022;Jánosi et al, 2023), and the Sand Ridge in the Danube-Tisza Interfluve (Sand Ridge abbreviated as SR or named Homokhátság in Hungarian) is one of the most exposed regions within Europe (Kovács et al, 2017). Thus, since the mid-90s, the SR has garnered attention in the literature primarily because of its aridification and landscape degradation (Pálfai et al, 1998;Bartholy et al, 2005;Cserny & Füleky, 2008;Bíró, 2011;Rakonczai et al, 2021). The region's name has become synonymous with unfavorable changes in hydrological balance, declining groundwater levels, and the deterioration of other ecological parameters (Bíró et al, 2007;Molnár & Balázs, 2009;Rakonczai, 2011).…”

There 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.
