“…Su uso permite identificar parámetros como la fecha de comienzo de la estación de crecimiento o el periodo de máxima actividad fotosintética. Derivado de ello, permite distinguir zonas agrícolas de regadío, altamente nitrificadas y donde más infiltración se produce (Dzurella et al, 2015;Merchán et al, 2020). Las 13 características fenológicas utilizadas fueron extraídas a partir del análisis de series temporales de NDVI calculados a partir de compuestos semanales de reflectancia de superficie del producto MODIS MOD09Q1.…”

This contribution uses anonymous mobile phone data to study the impact of the Spanish lockdown on the daily dynamics of the Madrid metropolitan area (Spain). The analysis has been carried out for a reference week prior to the lockdown and during several weeks of the lockdown in which different restrictions were in place. During these weeks, presence profiles are obtained throughout the day for each type of land use. In addition, a multiple regression analysis is carried out to determine the impact of the different land uses on the local population. The results in the reference week, pre-COVID-19, show how the population in activity areas increases in each time slot on a specific day and how in residential areas it decreases. However, during the lockdown, activity areas cease to attract population during the day and the residential areas therefore no longer show a decrease. Only basic essential commercial activities, or others that require the presence of workers (industrial or logistics) maintain some activity during lockdown.

“…3 Groundwater contamination is attributed to nonpoint sources of contamination (excessive use of pesticides, mineral and natural fertilizers), adaptation of old wells into permeable septic tanks, unsanitary landfills, uncontrolled waste disposal and discharge of untreated wastewater. [4][5][6] Temporal and spatial distribution of physico-chemical pollutants, mainly nitrogen compounds is essential for evaluation of groundwater quality [7][8][9] . The uncontrolled urbanization in the vicinity of protected areas affects groundwater quality causing the contamination with nutrients from agriculture, waste disposal and discharge of untreated mixed urban wastewater.…”

Research results define basis for specific monitoring programs of gro-undwater quality in wetland eco-systems in Serbia and Croatia. The main pur-pose of the research was to determine the impact of nonpoint diffuse source pollution on the groundwater quality, as well as seasonal variations on the con-centration levels of selected physico-chemical parameters. Statistical analyses, PCA, HCA, ANOVA and t-test, encompass 18 monitored parameters in ground-water. Statistical data indicated that protected area in Serbia has a significantly higher load of pollution from agricultural activities compared to Wetlands Tompojevci. The highest load in groundwater was detected from total nitrogen, ammonia and nitrogen anions, indicating contamination of groundwater by nitrogen-based fertilizers. The results obtained within the two-year seasonal monitoring program, from 2018 to 2020, are highly essential for achieving a comprehensive database that could be used as platform for high-quality groundwater management in selected protected areas with the aim of minimizing environmental pollution.

“…Mineral exploitation, chemical enterprise operation, pesticide and fertilizer application, sewage discharge and vehicle emissions are sources of pollution on agricultural land [7]. The use of large quantities of inorganic fertilizers to meet the N demand of crops, in combination with the return flow associated with irrigation, has increased NO 3 -concentrations in surface water bodies and the groundwater of agricultural areas in particular [16]. Phosphorus (P) loading in lakes degrades the quality and usability of water globally [17].…”

Influence of Anthropogenic Loads on Surface Water Status: A Case Study in Lithuania

et al. 2021

Twenty-six water bodies and 10 ponds were selected for this research. Anthropogenic loads were assessed according to pollution sources in individual water catchment basins. It was determined that 50% of the tested water bodies had Ntotal values that did not correspond to the good and very good ecological status classes, and 20% of the tested water bodies had Ptotal values that did not correspond to the good and very good ecological status classes. The lake basins and ponds received the largest amounts of pollution from agricultural sources with total nitrogen at 1554.13 t/year and phosphorus at 1.94 t/year, and from meadows and pastures with total nitrogen at 9.50 t/year and phosphorus at 0.20 t/year. The highest annual load of total nitrogen for lake basins on average per year was from agricultural pollution from arable land (98.85%), and the highest total phosphorus load was also from agricultural pollution from arable land (60%).
