The article describes the scientific and methodological foundations of spatial geoecological modeling of the natural and agricultural potential of the region’s landscapes, the theoretical basis of which is the methodology of multiparameter analysis of complex objects, implemented in the form of two methods: summary indicators and randomized summary indicators. The essence of modeling is in mathematical-cartographic spatial analysis in the GIS environment of the favorableness of natural landscapes for environmentally friendly agricultural production. It is based on the principles of consistency, priority of the assessed indicators, continuity, regionality, emergence, scale, visibility of the display of results. During the development of the scientific and methodological foundations, the following methods of geographical research were used: ranking the properties of landscapes by their impact on the natural and agricultural potential, building model-classifications for assessing the natural-agricultural potential, convolution of multi-parameter information in conditions of information deficit. The developed method includes six blocks. The method has been tested in the Leningrad Region. The results of approbation do not contradict the data of other researchers obtained for the studied region. The developed method can be applied in land management and territorial planning.

In order to increase the efficiency of land use- and territorial planning, cartographic materials of various thematic contents are required. In the article, the authors propose a methodology of assessing and mapping the favorability of the natural and agricultural potential of landscapes for agricultural use to increase its efficiency using GIS technologies. It is proposed to obtain information on landscapes by means of geoecological assessment, including a multivariate mathematical-cartographic, and spatial analysis of landscape conditions for sustainable environment-friendly agricultural production. Geoecological conditions make an integral indicator of the natural and agricultural landscape. To assess the land for agricultural production, maps are used, according to which the quality of the land plot is determined through the convolution of normalized indicators of the territory’s favorability, while the map is created in the GIS environment of spatially-linked information on the degree of the agro-resource suitability and geoecological conditions for agricultural production. Indicators of agro-resource and geoecological state of landscapes were established. The first ones include the agroclimatic potential and soil bonitet, and the second – the ecological and geochemical resistance of soils to acidification, erosion, ecosystem diversity of the territory, the density of the hydrographic network, the depth of groundwater, and the erosion potential of the relief. The developed technique is tested on Volkhov landscape of Leningrad oblast. The aim of the research is to develop a methodology for assessing and mapping the natural and agricultural potential of landscapes in the GIS environment and to test it on the territory of the region.

The Decentralized Autonomous Government of the province of Chimborazo promotes the agricultural productive development of the province by promoting entrepreneurship, and improving the capacities of producers, access to production factors, and integration of actors and subjects of agriculture and management on the basis to strategic planning. The construction of the Chimborazo Competitiveness Agenda was a participatory process that identified opportunities to improve the agricultural sector, where agricultural production at the primary level was recognized as a vocation and strength of the province; however, a strategic necessity was to establish possibilities of adding value and diversifying agricultural production. The definition of a set of agricultural products with high potential at the primary level and/or in agroindustrial processes that are not deeply explored required determining market signals to identify new medium- and long-term commercial possibilities for Chimborazo farmers. Additionally, it was recognized that the management of the province of Chimborazo was based on its management of the Millennium Development Goals, the Constitution of the Republic, the National Plan for Development in a Supra-Provincial Framework, as well as the Plan Development of Chimborazo, the Territorial Planning Plan and others that promoted planning with a focus on territorial and solidarity sustainable development. Keywords: Chimborazo, productive development, entrepreneurship, agricultural sector. Resumen El Gobierno Autónomo Descentralizado de la Provincia de Chimborazo impulsa el fomento productivo agrícola de la provincia mediante la promoción del emprendimiento, el mejoramiento de las capacidades de los productores, acceso a factores de producción, integración de los actores y sujetos del agro y gestión en base a una planificación estratégica. Como parte de dicho accionar, la construcción de la Agenda de Competitividad Chimborazo fue un proceso participativo que identificó oportunidades para mejorar el sector agrícola, donde se reconoció la producción agrícola a nivel primario como una vocación y fortaleza de la provincia, no obstante, una necesidad estratégica fue el establecer posibilidades de agregación de valor y de diversificar la producción agrícola. La definición de un conjunto de productos agrícolas con alto potencial a nivel primario y/o en procesos agroindustriales que no están profundamente explorados requirió determinar señales de mercado para identificar posibilidades comerciales nuevas a mediano y largo plazo para los agricultores de Chimborazo. Adicionalmente, se reconoció que la gestión de la provincia de Chimborazo tuvo como base los Objetivos del Milenio, la Constitución de la República, el Plan Nacional de Desarrollo en un marco supra-provincial, así como el Plan de Desarrollo de Chimborazo, el Plan de Ordenamiento Territorial y otros en su conjunto que promovieron una planificación con un enfoque de desarrollo sostenible territorial y solidario.

An ecological and economical aspect of restoration and organization of use of recultivated lands in agriculture are considered. It is proved that the price of the land which is withdrawn from agricultural production, consists of the price of the importance of the land as nature component, from the land price as basic method of production etc. The methodological workings out for the evaluation of the mine technical stage of land recultivation are offered. It is emphasized, that in any case recultivation of the disturbed lands should be directed on the localization and neutralization of harmful influences on the environment, and on creation of conditions for restoration of fertility of the disturbed lands, especially with use of chernozem mass which preliminary was removed from a disposal area. These are considerable expenses because losses from the agricultural lands consist of the losses from soil losses as the basic means of an agricultural production, from short-received profit in connection with deficiency of soil for restoration of the former productive area and from compensation of the lost agricultural potential. It is noticed, that in the course of carrying out of separate excavation of the fertile layer of chernozem, its transportation and placement in collars, and also application on the leveled surface of the disposal area and planning of this entire surface, the soil undergoes so-called impoverishment, that is mixing of fertile horizons with potentially fertile soils. This process is accompanied by decrease, first of all, content of humus which quantity on the average in 1.5–2 times is less, than in humus horizon of zone chernozems. Thus, the more powerfully layer of the piled mass of chernozem on the rock, so match the bigger was the content of humus which, however, never exceeds a natural indicator. For the first time in the conditions of Steppe Prydniprovia it was carried out the valuation of the basic types of artificial soils at some leading mining enterprises. For the standard is taken the average index of content of humus in not broken old arable lands in a place of creation artificial. Economic calculations have shown, that recultivated lands which have a point 40 and above (content of humus about 2 % and more), are suitable for cultivation almost all agricultural crops. The lands, that have the point from 40 to 20 – are suitable for introduction of hay harvests and hay-fields, and also wood and fruit – and – berry plantings. The lands with an ecological and economical point less than 20 should be used for creation of recreational zones, athletic fields, plots for holiday visitors in the country, forbidden lands, etc. It is affirmed, that those types of soils which have not chernozem soil cover, but are potentially fertile (on occasion), it is possible to involve in agricultural production. These are loess, loess – like loams, their mix with other soils, and also grey-green clay and red-brown clay on which the farmers receive high and stable yield of multicomponent grass mixtures. But in any case, the indicator of the mark estimation decreases owing to mass losses of humus horizon, its impoverishment, reduction of capacity of the layer of fertile chernozem, unsatisfactory carrying out of amelioration operations and chemical kinds of land improvement. These lacks harm to use of recultivated lands in an agricultural production at that level on which they were used earlier. It is established, that recultivated lands as the material substance, are capable to perceive additional investments of work and means. Their fertility is an objective ecological and economical category, which is formed as result of interaction of properties of the created lands, productive forces and industrial relations.

In the land of Nema, fields show low agricultural potential due to high human and climatic pressure. To increase their agricultural production, the populations have opted either for the use of chemical fertilizer or for the supply of manure through the Agriculture-Livestock integration. This paper focuses on evaluating the effect of on-farm use of manure on groundnut pod and groundnut production, and nutrient balance at the field level. 20 square plots of 2m each were used per field on the monitored farms. The hay and pod samples were taken therein, weighed, and dried in an oven at 60° C to a constant weight. This work was carried out for both fertilized fields and unfertilized fields (controls). In these same farms, samples of manure produced were collected and analyzed. The production of peanut and groundnut pods in the fertilized fields and in the control fields shows an overall positive effect of the manure on the yields in the land of the Néma. Taking into account the figures of the average deficits, the nitrogen, phosphorus, and potassium balance is deficient in ground-level groundnut peanut fields. This is due to the low manure doses per hectare and its low nutrient content.

Agriculture represents without any debate a fundamental economic sector, with significant implication in achieving not only the food safety standards for a growing population, but also in promoting rural communities' cultural values and providing good living standards and revenues for farmers and rural population. In this context the evolution of agricultural production structures represent a major concern for all decision-makers involved in this sector. Achieving competitive results in valuing the agricultural potential impose a great convergence between inland agricultural policies and the Common Agricultural Policy in order to integrate the best measures in designing an economically efficient agricultural structure. The chapter aims to analyze the evolution of some of the agricultural production structures under the Common Agricultural Policy reform and the pressure to adapt and achieve the most functional decision in a better valorization of the inland agricultural potential.

The monograph presents a methodology for assessing the vulnerability of landscapes to external influences. A comparative analysis of the concepts of "stability", "sensitivity", "vulnerability" in relation to natural complexes. An overview of existing methods for assessing the vulnerability of natural complexes is presented. The author's method of assessing the vulnerability of landscapes to anthropogenic impacts is described. The methodology is based on: selection and justification of criteria for assessing the vulnerability of landscapes; preparation of a parametric matrix and gradation of assessment criteria in accordance with the developed vulnerability classes; calculation of weighting factors of vulnerability assessment parameters; selection of optimal territorial operational unit for landscape vulnerability assessment. The method is implemented in the GIS environment "Assessment of vulnerability of landscapes of the Kaliningrad region to anthropogenic impacts", created by the authors using modern geoinformation products. The specificity of spatial differentiation of different landscapes in terms of vulnerability to anthropogenic impacts at the regional and local levels is revealed. It is stated that the use of the methodology for assessing the vulnerability of landscapes to anthropogenic impacts and its integration into the system of nature management will ensure a balanced account of geoecological features and environmental priorities in territorial planning. It is of interest to specialists in the field of rational nature management, environmental protection, spatial planning.

Presently, most models of crowd evacuations within a building are created manually. This is inefficient. To address this issue, this paper focuses on the differences and relationship between industry foundation classes (IFC) and the macroscopic network model for evacuation (MNME), and studies the mapping and construction methods used to convert entity objects into nodes and arcs in the MNME. Furthermore, corresponding attribute information in the MNME are established from IFC. Based on this process, the MNME is created and used as an input to EVACNET4 to obtain simulation results. Finally, the results, together with a 3D building model, are expressed in a unified environment. Our study results show that a network as well as the relevant attributes can be automatically generated from IFC, and can be adapted to different working conditions. The method proposed in this paper can automatically map the semantic information model to the MNME and the simulation result as well as the building model can be integrated in a Geographic Information System (GIS) environment.

Os grandes aglomerados urbanos desencadeiam profundas problemáticas de natureza hidroclimática, resultantes principalmente das formas de uso e ocupação do solo. Os padrões hídricos, tais como escoamento e acúmulo de fluxo, são afetados diretamente pelo efeito de impermeabilização do solo decorrente das construções humanas e quando esta estrutura urbana é somada aos eventos climáticos extremos, culminam na ocorrência periódica de inundações. Diante deste contexto, o presente estudo tem como objetivo compreender e identificar os danos hidrológicos decorrentes da concentração urbana, sobre a dinâmica natural do escoamento, a fim de investigar os fatores que provocam estas inundações nas determinadas regiões. A área de estudo do presente trabalho é representada por folhas de amostragem do sensor LiDAR das Regiões político administrativas IV e VI do município do Recife, Pernambuco. Para subsidiar a análise proposta, os modelos digitais de elevação do projeto Pernambuco 3D, provenientes do sensor LiDAR, foram processados em ambiente SIG, e a partir destes dados de alta resolução espacial foi possível analisar detalhadamente as variáveis que propiciam o escoamento superficial e acúmulo de fluxo nas áreas em estudo. Os resultados obtidos para as áreas de amostragem, foram analisados e comparados com as políticas públicas de drenagem urbana e planejamento territorial vigentes, avaliando a relação entre as redes de macro e microdrenagem, com a ocorrência de inundações no meio urbano. The use of lidar data for the understanding of water flow and accumulation dynamics in the Recife – PEA B S T R A C TLarge urban agglomerations result in huge problems of hydroclimatic nature, resulting mainly from the forms of land use and occupation. Water patterns, such as runoff and flow accumulation, are directly affected by the waterproofing effect from human constructions, and when added to the extreme weather events, they culminate in a periodic occurrence of urban floods. The study area of the present work is represented by the LiDAR sensor sampling sheets from the administrative political Regions IV and VI of the municipality of Recife, in Pernambuco. Given this context, the present study aims to understand and identify the hydrological damage caused by the urban concentration on the natural dynamics of runoff, to investigate the factors that cause these floods in that specific region. To subsidize the proposed analysis, the digital elevation models of the Pernambuco 3D project, from the LiDAR sensor, were processed in a GIS environment, and from these high spatial resolution data it was possible to analyze in detail the variables that propitiate surface runoff and flow accumulation in the areas under study. The results obtained for the sampling areas were analyzed and compared with the urban drainage and territorial planning public policies in force, evaluating the relationship between the macro and micro drainage networks, with the occurrence of floods in the urban environment. Keywords: Geoprocessing. remote sensing. urbanization. urban flood. surface runoff.
