A study area covers Ninh Binh Province as a whole that has 67.125 hectares of agricultural land, including 55.125 hectares of arable land. Ninh Binh has 13 major drainage basins. Water resources are unevenly distributed across the catchment areas. Due to a dense drainage system, every year Ninh Binh is hit by heavy flooding during the wet season. With a total length of all channels and a lock-weir network, just 22.4 % of channels are concrete lined, i.e. only every fourth kilometer of channels is concreted, thus leading to high irrigation losses. To tackle current challenges related to the effective use of irrigation systems in Ninh Binh, it is necessary to organize annual inspections and assessments of the current state of water supply networks, irrigation systems, etc.
The article considers problems and prospects of reducing the risks of occurrence of emergency situations of natural and technogenic character in the coastal river areas, as well as the usage for operational informing of the population of a comprehensive system that includes Federal, regional and local information centres. It is shown that the solution of the problem is based on the formation of information about emergency situations, their consequences, the state of radiation, chemical, medical, biological, explosive, fire and environmental safety in these areas, taking into account the coastal and transboundary situation to ensure their sustainable development. The authors defined the indicators and presented a strategy for collecting information and proposed a comprehensive system of support for management decisions aimed at preventing natural and man-made emergencies for the river coastal territory (RCT) of the Far East regions.
Land use in the Republic of Tajikistan is characterized by very difficult conditions for conducting useful economic activities. The crop industry is experiencing a shortage of suitable arable irrigated land (total arable land, according to various estimates, makes up about 5% of the total area of the country), which is clearly expressed in the decline in gross agricultural production. Scientists and practitioners have noted negative trends, indicating a decrease in specific indicators of per capita provision of agricultural land. All this necessitates the development of mechanisms and methods for a qualitative study of the current state of land use and the development of recommendations to prevent its further degradation. The article sets forth material that relates to the current state and prospects of obtaining and processing updated data on irrigated lands of the Republic of Tajikistan using modern information and communication technologies and GIS. It is shown which factors are constraining and which factors are stimulating in the republic. The practical significance lies in the fact that the results of the study can be useful in the study of the condition and use of irrigated lands, as well as in the effective management of these lands.
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.
