Abstract The article focuses on the issue of agricultural soil sealing in the Dolní Věstonice and Modřice cadastres (South Moravian Region). Available data and map resources were used for this purpose (historical and up-to-date). Data was processed using manual digitalisation which helped to generate the needed map output. The decrease in area of agricultural land is analysed in individual periods starting in the year 1824 (source of data stable cadastre - the first half of the 19th century) until the present, and the sealing of different types of plots and soil kinds is assessed according to Evaluated Soil-Ecological Units (ESEU). In most cases, agricultural land sealing is associated with municipal expansion. To compare future development, potential (forthcoming) agricultural land sealing proposed within the valid landscape plans was also explored. Likewise, the overall price of sealed plots in both locations was calculated. The results show that there was a significant change in the use of both model territories between 1824 and the present. In Modřice, the area of the built-up area was changed from 16 ha (1824) to 409 ha (2016). The area of the site has expanded from 90% to agricultural land. The most significant change in this area is the development of builtup areas on agricultural land. In the model territory of Dolní Věstonice, the area of the built-up area increased from 16 ha (1824) to 48 ha (2016). The area of the site has expanded from 70% to agricultural land. Due to the construction of water reservoirs “Nové Mlýny”, the area of water bodies increased by 569 ha (during the period 1824- 2016). The water reservoirs occupy 65% of the cadastral area of Dolní Věstonice. The most significant change in landscape is the increase in water areas in Dolní Věstonice. Should this trend persist, an extensive reduction in agricultural soil and ensuing problems associated with sustainable agriculture, potentially also deficient food resources must be anticipated.

SummaryWe have analyzed the loss of agricultural land in a case study of the community Eggelsberg in the Innviertel in Upper Austria. The trigger for the project was the attribution of Austria as Europe’s leader in soil sealing. We compared the results of the Austrian agricultural soil survey of the 1970s with the actual land use and quantified the land use change. Within half a century, 15% of the agricultural area was converted to settlement area or to other forms of infrastructure. According to the original soil assessment, 96 ha of high-quality cropland, 1,220 ha of medium-quality cropland, 121 ha of low-quality cropland, and 409 ha of grassland were converted. The forest cover remained stable. The highest share of soil sealing was owed to the expansion of the settlement area and the construction of a successful enterprise. Minor contributions were expansions of farm buildings. The loss of agricultural land was reasonable and reflected the needs of the local population. A special protection status because of the future relevance of the agricultural land was not communicated to land managers and is not reflected in the market prices of agricultural products. The relevance of the agricultural land beyond the regional level is not fully recognized.

Karst features such as polje are highly vulnerable to natural and anthropogenic pollution. The main objectives of this study were to investigate the soil quality in the Ioannina polje (north-west Greece) concerning arsenic (As) and zinc (Zn), and delineate their origin as well as compare the As and Zn content in soil with criteria recorded in the literature. For this purpose, the geomorphological settings, the land use, and the soil physicochemical properties were mapped and evaluated, including soil texture and concentrations of aqua-regia extractable As and Zn. The concentration of elements was spatially correlated with the land use and the geology of the study area, while screening values were applied to assess land suitability. The results reveal that 72% of the total study area has a very gentle slope. This relief favors urban and agricultural activity. Thus, the urban and agricultural land used cover 92% of the total area. The spatial distribution for As and Zn in the soil of the study area is located on very gentle slopes and is strongly correlated with the geological parent materials and human-induced contamination sources. Arsenic and Zn can be considered enriched in the soil of the area studied. The median topsoil contents (in mg kg−1) for As (agricultural soil 16.0; urban soil 17.8) and Zn (agricultural soil 92.0; urban soil 95.0) are higher compared to the corresponding median values of European topsoils. Land evaluation suitability concerning criteria given from the literature is discussed. The proposed work may be helpful in the project of land use planning and the protection of the natural environment.

The Impact

This paper develops a lexicographic optimization model to allocate agricultural and non-agricultural water footprints by using the land area as the influencing factor. An index known as the water-footprint-land density (WFLD) index is then put forward to assess the impact and equity of the resulting allocation scheme. Subsequently, the proposed model is applied to a case study allocating water resources for the 11 provinces and municipalities in the Yangtze River Economic Belt (YREB). The objective is to achieve equitable spatial allocation of water resources from a water footprint perspective. Based on the statistical data in 2013, this approach starts with a proper accounting for water footprints in the 11 YREB provinces. We then determined an optimal allocation of water footprints by using the proposed lexicographic optimization approach from a land area angle. Lastly, we analyzed how different types of land uses contribute to allocation equity and we discuss policy changes to implement the optimal allocation schemes in the YREB. Analytical results show that: (1) the optimized agricultural and non-agricultural water footprints decrease from the current levels for each province across the YREB, but this decrease shows a heterogeneous pattern; (2) the WFLD of 11 YREB provinces all decline after optimization with the largest decline in Shanghai and the smallest decline in Sichuan; and (3) the impact of agricultural land on the allocation of agricultural water footprints is mainly reflected in the land use structure of three land types including arable land, forest land, and grassland. The different land use structures in the upstream, midstream, and downstream regions lead to the spatial heterogeneity of the optimized agricultural water footprints in the three YREB segments; (4) In addition to the non-agricultural land area, different regional industrial structures are the main reason for the spatial heterogeneity of the optimized non-agricultural water footprints. Our water-footprint-based optimal water resources allocation scheme helps alleviate the water resources shortage pressure and achieve coordinated and balanced development in the YREB.

The main focus of this chapter is the highly valued work done by the architect Francesco Pieroni at the Ministero delle Finanze in Rome. This contribution can to attribute to Pieroni various drawings and numerous modine, i.e. real scale cardboard templates of various shapes used in the realization phases of the mouldings. Pieroni's activity represents, in the Roman context, one of the first applications of typical 16th century mouldings, to modern and prefabricated metal bar structures, spreading in the 70's of the 19th century. The construction companies were resilient to agree for changes in building techniques due to a lack of expertise. The realization of the Ministero is a case study of this phenomenon. The archival research developed casts new light on the numerous modifications carried out by Peroni during construction phases, which demonstrate the accuracy employed by the architect in designing the stuccos. The chapter analyses two different types of archive documents: the report Spoglio modificazioni lavori di stucco, and the examples of modine authored by Pieroni.

Land Use And Cover

Urbanization changes the land surface environment, which alters the regional climate system. In this study, we took the Haihe River Basin in China as a case study area, as it is highly populated and experienced rapid urbanization from 2000–2015. We investigated how land use and cover change (LUCC) was driven by urban land development affects land-climate dynamics. From 2000–2015, we collected data from the land use and cover database, the remote sensing database of the Moderate Resolution Imaging Spectroradiometer (MODIS) series, and the meteorological database to process and generate regional datasets for LUCC maps. We organized data by years aligned with the selected indicators of land surface, normalized difference vegetation index (NDVI), albedo, and land surface temperature (LST), as well as of regional climate, cloud water content (CWC), and precipitation (P). The assembled datasets were processed to perform statistical analysis and conduct structural equation modelling (SEM). Based on eco-climatology principles and the biophysical process in the land-climate dynamics, we made assumptions on how the indicators connected to each other. Moreover, we testified and quantified them in SEM. LUCC results found that from 2000–2015 the urban area proportion increased by 214% (2.20–6.91%), while the agricultural land decreased by 7.2% (53.05–49.25%) and the forest increased by 4.3% (10.02–10.45%), respectively. This demonstrated how cropland intensification and afforestation happened in the urbanizing basin. SEM results showed that the forest had both positive and negative effects on the regional hydrological cycle. The agricultural land, grassland, and shrub had indirect effects on the P via different biophysical functions of LST. The overall effects of urbanization on regional precipitation was positive (pathway correlation coefficient = 0.25). The interpretation of how urbanization drives LUCC and alters regional climate were herein discussed in different aspects of socioeconomic development, biophysical processes, and urbanization-related atmospheric effects. We provided suggestions for further possible research on monitoring and assessment, putting forth recommendations to advance sustainability via land planning and management, including agricultural land conservation, paying more attention to the quality growth of forest rather than the merely area expansion, integrating the interdisciplinary approach, and assessing climatic risk for extreme precipitation and urban flooding.

Bangladesh is a land scarce country where per capita cultivated land is only 12.5 decimals. It is claimed that every year about one percent of farm land in the country is being converted to non-agricultural uses. The study is based mainly on field survey covering 2 villages (Narikel Baria and Baze Silinda) from 10 sub-urban villages around Rajshahi City Corporation under Paba Upazila of Rajshahi district. The study area was selected purposively and the respondents of this research work were selected randomly. The major focus was on to mention the general land use pattern of the area, estimates the agricultural land conversion besides determining the causes and consequences affecting such conversion. Both Narikel Baria and Baze Silinda villages were selected as study area because of its relatively higher growth in infrastructure. In order to fulfill the goal of this study, primary and secondary data were collected from various sources and to analyze and process of collected data the SPSS, Excel and Arc GIS software were used. Different types of descriptive statistics were applied for representing the analyzed data. It is observed that the land conversion form agriculture to non-agriculture allied in recent time is more than the previous time due to gradually increasing land demand in housing and relevant services which invites adverse impact on agricultural land as well as its dependent population. So, it is necessary to take integrated land-use planning to offer better options for the fulfillment of land demand both of housing and agricultural sectors.
