In social-ecological systems, natural resource management can be characterized by trade-offs across sectors and sustainability targets. The water-energy-food (WEF) nexus concept makes explicit various trade-offs in order to maximize synergies of interventions. However, there are few successful examples of its operationalization in research settings. Here, we explore in a learning setting if sustainability impact assessment (SIA) protocols can be a useful process to be used to adopt a systemic, interdisciplinary perspective to operationalize WEF nexus in research for sustainable development. The process and method adopted of SIA protocol, evaluated for five exemplary WEF nexus cases in Central Asia during a week-long international workshop, adequately addressed the complexity of WEF interrelationships and associated sustainability issues, and facilitated a comparative case study analysis across scales. Results within this process highlight that water governance was critical for large-scale transboundary WEF nexus management, while land and soil management were decisive for minimizing trade-offs at local levels. Issues of interdisciplinarity, complexity, uncertainty, and reflection on impacts were adequately addressed, but challenges remain in the consideration of ethics and the design of transparent, multi-actor cooperation. Most importantly, this exercise showed that employment of the process of SIA protocol supported disciplinary experts to work across disciplines and take a systemic approach for analyzing WEF nexus.
Nowadays we can clearly see the activeness of the methodological and technological aspects of the new geoinformation direction in the field of cartography. The development of modern mapping methods is closely related to the development of geoinformation systems and technologies. The importance of geoinformation cartography and geoinformation systems is significant in creating databases and digital maps based on GIS software instead of analog methods for creating maps. There are the most important tasks such as improvement of modern method in obtaining cartographic information, and development of ways to quickly transmit and distribute cartographic information about nature and society. The application of GIS technologies in the field of demographic cartography will lead to drastic changes in the scope of work, as well as improve product design and increase the accuracy as a result of the performed tasks. The study shows that there is a need to develop a new method for mapping a new generation based on GIS technology, reflecting demographic processes. This article will focus on creating a database for development of maps based on GIS technologies, rapid identification, monitoring spatial changes using data from aerospace and other sources, and development of demographic digital mapping methods based on GIS technologies. Mapping demographic processes based on GIS technologies aims at implementing a number of practical tasks and research related to population. Based on this, a systematic method has been developed to analyse the demographic situation in the southern region of the Republic of Uzbekistan, and a digital demographic map has been created by applying the developed method.
Based on the collection and study of official data, the main criteria for selecting a land plot using GIS (Geographic Information System) technologies for the construction of a water treatment plant are presented. The main stages of data analysis are determined when solving the question of the location of the building using ArcGIS, ArcMap, ArcCatalog and it is scientifically proven that the use of such programs when choosing land plots for such types of construction can save in large amounts of material and labour resources. Together with these, in the conducted study, a methodology was developed and presented for the formation of a database necessary for compiling similar GIS projects, as well as a methodology for a feasibility study for the implementation of land allotment projects for the construction of various economic facilities. The advantages of using GIS technology for non-agricultural land use projects, which are the main form of inter-farm land use, which is a modern measure aimed at rational land use, are described. Key factors and key indicators, as well as expected project results.
Badland reclamation and low productive farmlands always have been one of the most detrimental effects on the national economy, typically in agricultural sector of Uzbekistan. Nonetheless, such kind of lands has been used extensively for major crops like cotton and winter wheat. However, it is difficult to assessing real productivity of them. Advanced technologies as GIS and RS are vital tool for geospatially analysing and making decisions on this type of fields. This research was carried out for real-time crop monitoring and yield forecasting in case of low productive (3.5 ha) and high productive (8.3 ha) cotton areas of Jarkurgan district (Surkhandarya region, Uzbekistan) based on geospatial analyses of multi-temporal satellite images, condition of groundwater, soil salinity, and ground truth data. For monitoring vegetation phenology of cotton and forecasting its harvest, False Colour, NDVI (Normalized Difference Vegetation Index) and SI (Salinity Index) analyses of areas were carried out by using 6 temporal windows of multi-temporal Sentinel 2 from April through August 2019. Besides, groundwater condition data which was obtained from observation wells these located in massives consists of both cotton fields was analysed by IDW (Inverse Distance Weighting) interpolation algorithm method to determine groundwater’s effect to vegetation development and yield.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
