The article is devoted to the improvement of the water resources management system at the territorial level. The article covers problems in different countries of the world, which are described in the water supply with an increase in the population of a harsh climate. Today, the existing trend shows that about two-thirds of forests and wetlands have been lost or degraded since the early 20th century, the soil was destroyed and deteriorated in quality. These trends predict floods and droughts, which in turn affects our ability to adapt to climate change. The analysis of the literature on the peculiarities of determining the main elements of influence on the use of water resources in the world is carried out. The article used a dialectical method, which is due to the need for analysis and generalization of certain aspects of scientific knowledge that analyze the availability of water resources in different parts of the world. Structural-functional analysis of the principle of systematic study of phenomena and processes is applied. With the help of the system-analytical method, the maintenance of the territories (areas) of Ukraine by local water resources is calculated, on average, per year, this m3 per person, based on the resource of surface water, as well as the exploration and catchment of groundwater. The decomposition of criteria for assessing the effectiveness of water resources management at the territorial level based on the integral territorial index is developed. According to the numerical value of the integrated territorial efficiency index, it is proposed to combine regions into homogeneous groups depending on the proximity or distance from the average value of this index.
Purpose. To develop a mathematical approach to quantitative assessment of the effectiveness of digital marketing of territories. To determine the tasks of digital marketing of territories and directions for increasing its effectiveness. Methodology. The research uses general and special methods of cognition: content analysis to substantiate the use of quantitative indicators for evaluating marketing effectiveness; induction and deduction for the development of a mathematical approach to evaluating the effectiveness of digital marketing of territories; analysis and synthesis to coordinate projects under conditions of a dynamic transformation of marketing processes. Findings. The mathematical formalization of quantitative evaluation effectiveness of marketing territories is developed, provided that the possibility of implementing project approach and conditions for coordination of projects is ensured. The tasks to be solved by the digital marketing of territories and directions for increasing its effectiveness are defined, and its advantages are detailed. The scheme is proposed for the implementation of territory marketing, taking into account the direct impact of information tools on the result and the reverse impact of an inappropriate result on the choice of information tools, which dictates the need to ensure the adaptability of marketing to dynamic changes in external and internal influences. Originality. The synergistic mutual influence of territory marketing and digital technologies, the synergistic mutual influence of business activities in the territorial location and the marketing of territories is established. It is established that the factor that determines the dynamic change in marketing plans is also a significant level of uncertainty due to the dynamic change in the level of threats and the dynamic nature of the introduction of the latest technologies. Practical value. The mathematical approach of quantitative assessment effectiveness of digital marketing territories and the determination of its tasks and directions for increasing efficiency determine the practical value of the study.
