The success of Russia's socio-economic development heavily depends on resource avail abi li ty , resource sufficiency, and resource diversity. Because economic resources (natural, human, capital, information, and material) represent a key barrier to regional social and economic development, the regional federal systems should take into account the effects of regional development drivers. This study aims to assess the level of economic development across economic regions in Russia regarding resource availability and develop state regulation measures to improve regional economic performance. For thi s, a l l regions were divided into groups by their gross regional product estimates. Fac to rs re fl ec ti ng e c onomi c performance were identified through factor analysis, and the cyclical nature of resources av ai la bil it y w a s discussed. The paper offers a resources availability model that allows determining the minimum a moun t o f resources required for a region having a specific level of economic development to a c hi ev e t he ma x imu m economic performance possible inless time. In addition, the paper presents a state regulatory framework for a regional economy that integrates financial support measures, state projects and programs, and me a sure s to modify the regulatory framework and the regulation of human resources. The proposed sta te re g ul ati on framework takes into account the full range of regional resources and makes it possible to choose t h e mo st effective tools with the view to meeting regional development goals

“…In this context, it is worth mentioning the need to develop public policies and implement land management plans in a manner that Cabouço area can be preserved from water pollution and legally protected for conservation of water resources. This study exposed the interdependency, availability, and accessibility of surface water and groundwater in Vila Pouca de Aguiar, and therefore contributed to identify and manage water security in the municipality [66]. We are therefore confident that the construction of Cabouço dam to complement drinking water supply in deficit areas and complementary irrigate the South Valley, would represent the most reliable route to follow in achieving sustainable use of local water resources.…”

The drinking water supply to Vila Pouca de Aguiar municipality in North Portugal is based on high quality groundwater, namely on nearly one hundred artesian springs and fifty boreholes. The groundwater resources are plentiful on a municipal level, but evidence some deficits at the sub-municipal (village) level, especially during the dry period (July- August) that coincides with the return of many emigrants for holiday time. The deficits affect mostly the municipal capital (Vila Pouca de Aguiar) and a neighboring village (Pedras Salgadas), which populations nearly double or even triple during that period. The estimated annual deficits approach 55,000 m3/yr in those villages. If the anticipated increase in consumption/habitant and decrease in annual rainfall become reality in the next two decades, then the deficits may raise to approximately 90,000 m3/yr. To balance the water supply system, this study proposes its transition towards a conjunctive water management based on surface water stored in small dams and groundwater. A hydrologic modeling involving small forested catchments (< 15 km2) elected the Cabouço watershed as most suited basin to store stream water, because surface water availability is large (2.4 Mm3/yr) and forest cover is dominant (84.8%). Estimated nutrient loads are also compatible with drinking water supply.

“…Besides the aforementioned water resources applications of hydrologic models in the GBM and the Mekong basin, Land Surface Models (LSMs) are also used as a core tool for understanding the spatio-temporal variation of hydrometeorological variables and associated physical processes. The importance of understanding the water cycle and quantifying its various fluxes using LSMs is even more acute in the case of ungauged and transboundary regions, where such data can prevent large-scale disasters (Siddique-E-Akbor et al, 2014;Murshed and Kaluarachchi, 2018). At this time, several operational global LSMs are producing continuous estimates of different hydrological fluxes, which can be used as an easilyaccessible alternative to locally-tailored hydrological models.…”

“…Khandu et al (2016) used GRACE along with soil moisture estimates from different LSMs to estimate the influence of precipitation extremes on the Total Water Storage (TWS) in the GBM basin. A recent study by Murshed and Kaluarachchi (2018) used GLDAS soil moisture data to estimate freshwater availability in the Ganges Delta and demonstrated how LSMs can be used to identify the complex issues of water security.…”

Numerical models have become essential tools for simulating and forecasting hydrometeorological variability, and to help better understand the Earth's water cycle across temporal and spatial scales. Hydrologic outputs from these numerical models are widely available and represent valuable alternatives for supporting water management in regions where observations are scarce, including in transboundary river basins where data sharing is limited. Yet, the wide range of existing Land Surface Model (LSM) outputs makes the choice of datasets challenging in the absence of detailed analysis of the hydrological variability and quantification of associated physical processes. Here we focus on two of the world's most populated transboundary river basins-the combined Ganges-Brahmaputra-Meghna (GBM) in South Asia and the Mekong in Southeast Asia-where downstream countries are particularly vulnerable to water related disasters in the absence of upstream hydro-meteorological information. In this study, several freely-available global LSM outputs are obtained from NASA's Global Land Data Assimilation System (GLDAS) and from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis-interim/Land (ERA-interim/Land) and used to compute river discharge across these transboundary basins using a river network routing model. Simulations are then compared to historical discharge to assess runoff data quality and identify best-performing models with implications for the terrestrial water balance. This analysis examines the effects of meteorological inputs, land surface models, and their spatio-temporal resolution, as well as river network fineness and routing model parameters on hydrologic modeling performance. Our results indicate that the most recent runoff datasets yield the most accurate simulations in most cases, and suggest that meteorological inputs and the selection of the LSM may together be the most influential factors affecting discharge simulations. Conversely, the spatial and temporal resolution of the LSM and river model might have the least impact on the quality of simulated discharge, although the routing model parameters affect the timing of hydrographs.
