Purpose. Research of space-time changes in the specialization of grain and leguminous crops of the plant complex of Kherson region. Methods. System analysis, statistical, mathematical and cartographic. Results. Using a statistical method, we collected and analyzed data on sown areas of cereals and legumes in 2015 - 2019 in the Kherson region. Based on statistical data, we calculated the coefficients of territorial localization and identified areas of specialization of grain production. Using GIS-technologies we have developed maps of specialization of districts of Kherson region.As a result of research, we have revealed the basic laws of development of agriculture of the Kherson region, in particular production of grain crops. We also conducted a spatial-temporal analysis of the development of agricultural production of cereals and legumes using the analysis of land resources. On the basis of modern research methods, we have typified the territory of the Kherson region, identified areas of specialization in the cultivation of cereals and legumes in terms of administrative districts of the region. This made it possible to identify factors influencing the specialization of the region. It is determined that among all crop industries of Kherson region, grain production has developed the most. Conclusions. The dynamics of development showed that such trends as: reduction of the total area of crops; change of areas of specialization on cultivation; increasing grain yields and increasing grain production, had a positive impact on the development of grain production. The directions of intensification of grain production for its optimization are offered: introduction of the newest technologies of cultivation; investment activity; improvement of biological aspects of production, selection activities and reproduction of soil fertility.

Spatial Temporal Analysis

<p>Phenological information can be obtained from different sources of data. For instance, from remote sensing data or products and from models driven by weather variables. The former typically allows analyzing land surface phenology whereas the latter provide plant phenological information. Analyzing relationships between both sources of data allows us to understand the impact of climate change on vegetation over space and time. For example, the onset of spring is advanced or delayed by changes in the climate. These alterations affect plant productivity and animal migrations.</p><p>Spring onset monitoring is supported by the Extended Spring Index (SI-x), which are a suite of regression-based models for key indicator plant species. These models (Schwartz et al. in 2013) are based on daily maximum and minimum temperature from the first day of the year (January 1<sup>st</sup>). The primary products of these models are the timing of first leaf and first bloom, but they also provide derivative products such as the timing of last freeze day and the risk of frost damage day (damage index) for each year. This information helps to understand if vegetation could have suffered from environmental stressors such as droughts or a late frost events. The effects of environmental stressors in vegetation could be captured by the false spring index, which relates the first leaf day and the last freeze day. Moreover, this information could be used to understand plant productivity as well as to evaluate the economic impact of climate change.</p><p>Previous works studied the relationship between remote sensing and plant level products by means of spatial-temporal analysis between Gross Primary Production (GPP) and a spring onset index. However, they did not consider the possible impact of false spring effect in these relationships. Here, we present a spatial-temporal analysis between GPP and the damage index to better understand the effect of false springs (in annual gross photosynthesis data). The analysis is done for the period 2000 to 2015 over the contiguous US and at spatial resolution of 1 km. We used the MODIS annual sum of GPP and the damage and false spring indices derived from the SI-x models.</p>

Due to its large territory, Brazil has different climatic regions, which determines biome variations and equally diverse ecosystems, of this variety of vegetal landscapes, accompanies the diversity of climates. In this context, results of studies carried out locally, which guide measures, decision-making laws and regulations that reach large scales in the territory, need to be carefully planned, because there is a high risk of disregarding environmental specificities of the studied areas. Therefore, this study aimed to analyze the environmental dynamics resulting from the impacts of the last decades that have affected the habitat of the guaiamum (Cardisoma guanhumi) in the Acaú-Goiana Extractivist Reserve (RESEX) and surrounding areas. The analysis of the spatial-temporal dynamics, in the RESEX and adjacent areas, was made from the vegetation indices (SAVI) through remote sensing. In this way, three images of the RESEX were analyzed, two from the year 2010 and one from 2015, in which the RESEX was already in full legal operation. It is noticeable that there are some areas within the Conservation Unit with small plots of exposed soil, which can demonstrate the occurrence of fires.

Inadequate waste management leads to many environmental issues and theadoption of an efficient and sustainable waste management has become apriority objective of the EU. However, besides the demographic factors, thevarious socio-economic and geographical conditions of this complex spacelead to major disparities in municipal waste management between North andSouth, East and West. This paper aims to do a spatial-temporal analysis ofthe Eurostat indicators using ascending hierarchical cluster analysis thatdivides the member states into five typological classes. The resulted mapshighlight territorial disparities among the Member States on municipalwaste management and also reveal the evolution of environmental policiesbetween 2003-2009 related to the EU acquis.
