Land consolidation is an activity that facilitates the improvement of the spatial structure and at the same time contributes to the sustainable development of rural areas. European Union (EU) funding helps to improve, among others the area structure of agricultural land in the EU countries.\u0000Aim: From these premises, the purpose of the work results, which is the assessment of the effects of the performed consolidation of land with EU funding. The detailed analysis covered 16 precincts from the Podkarpackie voivodeship and 3 precincts from the Świętokrzyskie voivodeship. The assessment of the consolidation of land was made in 19 consolidated objects in the years 2007-2020. In practice, there is a problem of how to demonstrate the effects of land consolidation? This article proposes to present the four most important effects of land consolidation in the form of the following coefficients: W1 (coefficient of reducing the number of plots as a result of consolidation), W2 (coefficient of increasing the average plot area in the consolidation facility), W3 (coefficient of reducing the number of plots in an individual farm as a result of consolidation), W4 (index of road network density in merged area) are a reliable image of the results of the land consolidation performed in the studied area.\u0000Results: The results were obtained. Index W1 in the examined objects indicated the result of 34.0% for the Podkarpackie voivodeship, and 28.8% for the Świętokrzyskie. Index W2 in the Podkarpackie voivodeship is 27.0%, and in the Świętokrzyskie it is higher and amounts to 29.7%. Index W3 which amounts to 39.4% of the average number of plots in a farm in the Podkarpackie voivodeship and much higher, amounting to 46.6% in the Świętokrzyskie. Index W4 for the Podkarpackie voivodeship is + 14.7%. However, for the Świętokrzyskie it is only + 3.7%. Summing up, the study analyzed four indicators showing the effects of land consolidation in southern Poland. The results obtained for these two voivodeships were similar. However, unsatisfactory in terms of the effects of land consolidation.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43162177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As cities respond to closure measures in order to flatten the infection curve, the challenges associated with the spread of the epidemic and the increasing numbers of infected and deaths that compel us to fundamentally rethink the formation of our cities, especially their streets, the research presents an urban review of the impact of the pandemic on cities and find solutions to recover, achieve a safe and sustainable healthy environment, and prepare better for any pandemic that may occur in the future, the research seeks to strengthen the theory of prevention, which the research proposes to call (urban immunity) by including social distancing as a design criterion in the city that has proven effective in flattening the curve.\u0000Aims: This paper focuses on the mechanisms related to sustainable mobility after COVID-19 in shaping urban mobility and initiating a green transformation in urban transportation rapidly by decarbonizing and promoting cycling and walking across all over the city. The research methodology depends on identifying the most important urban problems that Al-Dhubat Street suffers from and proposing solutions that reduce dependence on private transportation and move towards sustainable mobility as an important step in strengthening urban prevention against any epidemics that may occur in the future, and then testing indicators on the Al-Dhubat Street to identify effective indicators.\u0000Results: The research concluded that social distancing is the way back to active mobility by relying on walking and bicycles and works to restore the right of pedestrians in the streets and sidewalks instead of cars and thus achieve sustainable urban development, which enhances the urban immunity of the city against any other epidemics may occur in the future. With the proposed interventions on Al-Dhubat Street we can keep car use low and promote walking and cycling for a sustainable, equitable, habitable, and healthy community after the pandemic.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49081622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The choice of optimal adaptation solutions for cities is difficult as it requires an individual approach. One way of avoiding poor decisions is to use the experience of cities which have already implemented adaptation solutions. The aim of the work was to identify measures conducted as part of implementation of the municipal plan of adaptation to climate change for Poznań and to evaluate if the conducted measures complied with the adopted strategic goals specific for the research area. It was found that Poznań undertakes measures on each of the four specified strategic goals, but to a different degree. Hard measures and measures of the types: mitigation, physical infrastructure, and green infrastructure prevail. Most measures are performed in the sectors of transport and biodiversity. In addition, single cases of actions which have a negative impact on the natural environment have been identified.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42602342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It examines various definitions of the concept and explores its social, economic, and institutional dimensions as components of a dynamic system. The study design was a descriptive review of relevant material collected from high quality scientific databases using the purposeful sampling method. The results indicated that the social ecology model of urban resilience provided a coherent and dynamic approach to the study of urban resilience. This model comprises economic, social, and institutional dimensions, the components of which have different functions in relation to urban resilience in the face of changes and pressures. To be effective, the system must be flexible and contain a variety of resources and functions to make predictions, deal with adverse events, and make provision for possible failures. System stability and balance require active and knowledgeable actors and institutions that enable appropriate communication between them. In this approach, a resilient city not only has the ability to absorb and withstand disasters, but also contains a variety of internal and external resources to regain balance. Resilient systems are the result of a series of decisions and actions at different times. The necessary capacities must be developed in the economic, social, and institutional dimensions to create economic stability, increase awareness and public cooperation, and develop efficient institutions to legislate for and implement urban resilience programs.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46385206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are used for recreational purposes, and they contribute to improving social interactions and community cohesiveness. For this reason, the location and area of urban green spaces should correspond to the size of the city and its population.\u0000Aim: The main aim of this study was to analyze the accessibility of managed and publicly available urban green spaces, referred to as public urban green spaces (PUGS), in four functional and spatial zones in the city of Białystok. The analysis included parks, green squares (pocket parks, ornamental green squares, boulevards) and public forests. The accessibility of PUGS was determined in view of their size and role in the urban spatial structure. Spatial data were processed in GIS and quantitative analyses.\u0000Results: The study demonstrated that the area of PUGS per capita meets the requirements of the World Health Organization (WHO), but the area of parks and green squares should be increased. The accessibility buffers of public green spaces often overlapped, in particular in downtown Białystok (Central zone) which is most abundant in these green infrastructure components. The analysis also revealed locations that do not have access to urban green spaces. The results of the study were used to formulate guidelines for incorporating new green spaces in Białystok and improving the urban spatial structure.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47293074","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sesame is an important cash crop and plays vital role in the livelihood of many people in Ethiopia. However a number of challenges hindered the development of sesame sector along with the productivity.\u0000Aim: This study attempted to analyze production efficiency of sesame producers in Bench Maji Zone of Southwest Ethiopia. The study used both primary and secondary data sources. Purposive sampling techniques were employed to draw 270 sesame producer farm households. Descriptive statistics and econometric models were used to analyze the data.\u0000Results: The estimated stochastic production frontier model indicated that input variables such as inorganic fertilizer, sesame seed, oxen power, labor and chemicals found to be important factors in increasing the level of sesame output in the study area. The result further revealed significant differences in production efficiency among sesame growing farmers in the study area. Applying the Cobb-Douglas functional form the average, technical, allocative and economic efficiencies found are 50.72%, 86.83% and 44.2% for sesame producers, respectively. Also among fourteen variables used in the analysis of determinants, experience in sesame farming, education level, farm income, total cultivated land, social responsibility, frequency of extension contact, participation in off/nonfarm activities, credit, proximity to market and soil fertility were found to be significant sources of technical, allocative and economic inefficiencies of sesame producer farmers. Strengthening education, extension service, credit access at affordable interest rate and accessibility of transport services and motivating farm household to participate different training as well as their experience sharing with other sesame producing farmers improve productivity of sesame production. Therefore, those important socioeconomic and institutional factors which are mentioned above must take into account to improve the productivity of sesame in the study area.","PeriodicalId":36893,"journal":{"name":"Acta Scientiarum Polonorum, Administratio Locorum","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48762415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
