The article presents statistics on the number of pigs and poultry in Ukraine and Odessa region for 1990-2019 and the results of the calculation of needs for premixes and protein-vitamin supplements (PVS) in Ukraine, and in particular, in Odessa region, the average increase and volumes of compound feed consumption. The main purpose of the calculation is to determine the production potential of premixes and compound feeds in Ukraine and in the region, the cost of compound feeds in poultry farming using different types of premixes and PVS.According to the Main Department of Statistics in Odesa Oblast, the number of pigs has decreased over the past five years, and the number of poultry has increased by 7.3%.The calculation of the need for premixes and PVS is determined by the volume of feed production, the need for which depends on the number of livestock and poultry, data on their average growth and consumption of feed.The method of calculating the number of pigs and poultry (forecast) depending on the needs of the population in livestock food, as well as the results of the forecast of the number of pigs and chickens in Ukraine and Odessa region for 2020-2023, which amounted to 5702, 0 and 173.0 thousand goals, 224.8 and 3.3 million goals, respectively.The calculations taking into account the export-import potential of raw materials showed that in the Odessa region there is a shortage of capacity, namely: P mf forecast = 104819.6 thousand tons.  0, P mf forecast ≥ M year, ie 104819.6  9000.0 thousand tons, so in the Odessa region should provide a feed mill with a capacity of 15 thousand tons per shift in two shifts is appropriate and reasonable. The potential of production and sale of compound feeds in the Odessa region, which is up to 8500 thousand tons of feed, 85 thousand tons of premixes and 2430 thousand tons of PVS, calculated the main producers and consumers of feed products.The estimated economic efficiency of the use of feed enriched with complex premixes, as a result of which it is possible to reduce the cost of obtaining 10 eggs to 280 million UAH. per year, and in the fattening of suckling piglets - zeko-nomity in the production of pork up to 3.15 million UAH.

With the rapid development of society and the economy, the shortage of water resources and the deterioration of the water environment has resulted in restriction of the development of society and the protection of ecology and the environment. Consequently improving water efficiency is the key to realizing the sustainable utilization of water resources, and water efficiency evaluation is an important part of water resources management. Emergy theory aims to convert different dimensions of material and energy into solar energy, which can be analyzed and compared uniformly. Therefore, a new approach to assessing the economic efficiency of water resources, based on the water contribution to economic production, is evaluated using an emergy theory model. Water efficiency and system sustainability are explained by variables and emergy indicators in a regional water ecological–economic system (WEES) for Zhengzhou, China. The general status and economic efficiency of water resources in Zhengzhou are identified from the WEES. The average water contribution quantity and water contribution rate were 50.99 × 1020 sej and 6.13% during 2000–2011, respectively. Results also show that industrial water efficiency is higher than that of agriculture. This quantification method will help decision-makers to adjust water prices and provide better water services.

The Kaligesing area is part of the western part of the West Progo Dome. As the hard water area, water resources should be important problem to support rural development. The characteristics of the drainage as an indicator of water resources potential need to be understood in order to assess water potential. This paper wants to describe drainage characteristics as one of potential water resources indicators. The sufficient water resource is important for rural development. Result of the research shows that geological conditions allow this area to have relatively little water potential, but surface water can develop through rock-controlled flow patterns and geological structures. The flow characteristics in the area show rectangular, sub dendritic, and trellis patterns. Rivers develop genetically with consequent and subsequent types. Based on the quantity of water, the rivers in the study area include the intermittent and ephemeral rivers. Meanwhile, based on tectonics these rivers can be classified as superimposed rivers, where geological structures facilitate the formation of rivers in the research area. The river order in the study area shows the order of 1 - 4. Meanwhile, the density of the river is 0.81 - 1.86 km/km2 with young to mature river stages.

Abstract One of the major socioeconomic and global sustainability issues is water scarcity, which imperils human survival and regional development. The current study aims to develop a model for allocating water resources more efficiently and equitably. In this regard, a multi-objective programming approach was developed with the first objective of equality of water resource allocation to be maximized, and the second objective of risk to be minimized. The risk considered in this study was the economic efficiency loss risk. For the annual water allocation model, the fluctuation in available water within the river basin is the main source of uncertainty and can result in the corresponding risk of economic efficiency loss. Thus, it is essential to manage the economic efficiency loss risk resulting from uncertainty. To solve the model, the compromise programming (CP) method was used. A sustainability index was also employed to determine the objective function weights. The developed model was applied to the Givi River basin in Iran. From the results, it was found that using the sustainability index is a suitable strategy in the CP method for determining the objective function weights. The results showed that the proposed model can be helpful in water management to allocate water resources.

The spatio-temporal change of the surface water is very important to agricultural, economic, and social development in the Hetao Plain, as well as the structure and function of the ecosystem. To understand the long-term changes of the surface water area in the Hetao Plain, we used all available Landsat images (7534 scenes) and adopted the modified Normalized Difference Water Index (mNDWI), Enhanced Vegetation Index (EVI), and Normalized Difference Vegetation Index (NDVI) to map the open-surface water from 1989 to 2019 in the Google Earth Engine (GEE) cloud platform. We further analyzed precipitation, temperature, and irrigated area, revealing the impact of climate change and human activities on long-term surface water changes. The results show the following. (1) In the last 31 years, the maximum, seasonal, and annual average water body area values in the Hetao Plain have exhibited a downward trend. Meanwhile, the number of maximum, seasonal, and permanent water bodies displayed a significant upward trend. (2) The variation of the surface water area in the Hetao Plain is mainly affected by the maximum water body area, while the variation of the water body number is mainly affected by the number of minimum water bodies. (3) Precipitation has statistically significant positive effects on the water body area and water body number, which has statistically significant negative effects with temperature and irrigation. The findings of this study can be used to help the policy-makers and farmers understand changing water resources and its driving mechanism and provide a reference for water resources management, agricultural irrigation, and ecological protection.
