This paper presents an assessment of the costs of diffuse groundwater pollution by nitrates and pesticides for the industrial and the drinking water sectors in the Upper Rhine valley, France. Pollution costs which occurred between 1988 and 2002 are described and assessed using the avoidance cost method. Geo-statistical methods (kriging) are then used to construct three scenarios of nitrate concentration evolution. The economic consequences of each scenario are then assessed. The estimates obtained are compared with the results of a contingent valuation study carried out in the same study area ten years earlier.

Mathematical model was developed and evaluated to monitor and predict the groundwater characteristics of Trans-amadi region in Port Harcourt City. In this research three major components were considered such as chloride, total iron and nitrate concentration as well as the polynomial expression on the behavious on the concentration of each component was determined in terms of the equation of the best fit as well as the square root of the curve. The relationship between nitrate and distance traveled by Nitrate concentration by the model is given as Pc = 0.003x2 - 0.451x + 14.91with coefficient of determination, R² = 0.947, Chloride given as Pc = 0.000x2 - 0.071x + 2.343, R² = 0.951while that of Total Iron is given as Pc = 2E-05x2 - 0.003x + 0.110, R² = 0.930. All these show a strong relationship as established by Polynomial Regression Model. The finite element techniques are found useful in monitoring, predicting and simulating groundwater characteristics of Trans-amadi as well as the prediction on the variation on the parameters of groundwater with variation in time.

The article assesses the food security of municipalities in the Volgograd region based on indicators of self-sufficiency in agricultural products. It was proposed to adapt the methodology for calculating self-sufficiency indicators, replacing indicators of consumption of basic products in municipalities that are not publicly available with indicators of necessary production volumes in accordance with rational norms. This makes it possible to better assess the extent to which municipalities are able to provide the population with basic food supplies, as well as to identify bottlenecks in order to develop proposals to address them. The highest self-sufficiency ratios for the main types of products was noted in the municipalities of the North-Western agricultural region with most favourable conditions for agricultural activities and, conversely, the lowest figures are typical for agricultural Zavolzhsky area – with the less favourable agricultural conditions.

The article considers the reclamation park, which is an instrument of state stimulation of the development of economic entities of the agro-industrial complex on irrigated lands. On the example of the Rostov region, the authors analyzed the organizational, economic and regulatory mechanisms for the functioning of reclamation parks, as well as the socio-economic effects that arise in connection with the implementation of the specified tools. The results obtained can be used by state authorities of the Russian Federation, a constituent entity of the Russian Federation when drawing up plans for socio-economic development, developing strategies and programs, as well as by economic entities in managing agricultural activities.
