The survey was conducted from June 2022 to January 2023 to study the impact of Agro meteorology Advisory Services and to know the increases of production of cotton crops concerning the effect of weather parameters in selected villages under the DAMU project in NTR district, Andhra Pradesh. District Agromet Units (DAMU) which was established in Krishi Vigyan Kendra’s by Andhra Pradesh cooperative program of India Meteorology Department and Indian Council of Agricultural Research. The Main theme of DAMU is to provide timely location specific Agro-met advisories to the farmers at the sub divisional and district level. The agro meteorology advisory services were provided weekly twice among the sub divisions (Tuesday and Friday) and disseminated to farmers by including cotton growers using Whats App, emails and other print media. The impact assessment was based on feedback to come at significant illation in terms of using of Agro meteorology Advisory Service (AAS) by farmers. The assessment study revealed that the farmers who adopted agro advisory services on real-time basis obtained 18 % higher net return in cotton compared to Non-AAS farmers which were benefited by forecasting of rainfall for timely agricultural operations, the recommended dose of fertilizers, and efficient use of pesticides majors in a required support manner during different crop growth stages were advised in bi-weekly bulletins. AAS farmers benefited by timely application of insecticides and fertilizers, timely accurate weather forecasting and timely agricultural operations to gain more yield in cotton crop as compared to Non-AAS farmers. AAS might be used to be helpful to the farmers in managing and changing weather, finally decreased input cost in agriculture and acquiring cost-effective agricultural production by adopting of weather-based Agromet Advisory.

This study describes how farmers manage climate variability in dryland crop production, and aims to contribute to the theory and practice of decision support for managing climate variability. The intent was to study farmer decision making to see how DSS could be used to deliver information and procedures on climate risk to farmers more effectively. The study investigated whether there are significant differences between farmers' subjective distributions of seasonal rainfall and its derivatives (such as crop yield and fallow recharge) and a probability distribution derived from long-term records and simulation models, and whether these differences in risk assessment lead to changes in the optimum decision. Subjective probability distributions of rainfall and its derivatives were collected from farmers and advisers and it was found the overall match between these and long term records and simulation models was close. This study found little evidence to support the role of DSS for routine decision making, but this does not lessen the value of distributions derived from simulation models. Rather, it provides an opportunity for both farmers and scientists to learn.Doctor of Philosophy (PhD)

A evapotranspiração de referência (ETo, mm d-1) foi medida por um lisímetro de pesagem acoplado a três células de carga, durante 1996, em Piracicaba, SP. Discute-se as dificuldades operacionais encontradas com esse tipo de lisímetro em dias com chuvas intensas e em seqüência de dias com chuvas intermitentes. A série temporal dos valores medidos diariamente foi agrupada em seqüências de 10 ou 30 dias, gerando conjuntos de valores médios representativos dessas duas escalas de tempo. Média móvel com diversos passos foram usadas para aumentar o número de pontos nos conjuntos gerados e para verificar seus efeitos sobre as relações estatísticas. Estimativas de ETo médio correspondentes aos intervalos de tempo das médias medidas foram obtidas com a equação de Penman-Monteith seguindo-se as parametrizações e procedimentos descritos no boletim FAO-56, usando dados meteorológicos de uma estação automatizada situada próxima ao lisímetro. A análise de regressão linear simples (Lisímetro = b Estimativa) mostrou as seguintes tendências estatística: 1) na escala de 30 dias, Y = 1,0905 X ± 0,212 mm d-1, r2 = 0,9512 de janeiro a junho; e Y = 0,9622 X ± 0,166 mm d-1, r2 = 0,8249 de agosto a novembro; 2) na escala de 10 dias, Y = 1,0866 X ± 0,332 mm d-1, r2 = 0,9158 de janeiro a junho; e Y =0,9573 X ± 0,323 mm d-1, r2 = 0,7729 de agosto a novembro. Os diferentes passos não afetaram substancialmente o valor de b; mas, em geral, o erro médio da estimativa aumentou quando o passo aumentou, diminuindo o número de pontos comparados. Face às dificuldades de medir ETo em períodos chuvosos as relações obtidas no segundo período talvez expressem melhor o grau de ajuste das estimativas. A performance das estimativas não se alterou quando se substituiu o saldo de radiação medido por valor estimado usando os procedimentos FAO-56, simulando uma situação muito comum de ausência de medida desse elemento meteorológico.Reference evapotranspiration (ETo, mm d-1) was measured by a weighing lysimeter coupled with three load cells, during 1996, in Piracicaba, SP, Brazil. Operational difficulties with this kind of lysimeter during days with high intensity rainfall and also during a sequence of days with intermittent rains are discussed. The time series of measured ETo was pooled in sequences of either 10 or 30 days generating groups of mean values for such time scales. Moving averages with different steps were used to increase the number of points in each group and to test their effect upon the statistical relationships. Estimatives of mean ETo corresponding to the time intervals of the measured averages were computed with the Penman-Monteith equation following the parameterizations and procedures described in the FAO Irrigation and Drainage Paper 56, using data given by an automatic meteorological weather station located next to the lysimeter. Simple linear regression analysis (Lysimeter = b Estimative) indicates the following statistical tendencies: 1) for the 30-days time scale, Y = 1.0905 X ± 0.212 mm d-1, r2 = 0.9512 from january to june; and Y = 0.9622 X ± 0.166 mm d-1, r2 = 0.8249 from august to november; 2) for the 10-days time scale, Y = 1.0866 X ± 0.332 mm d-1, r2= 0.9158 from january to june; e Y = 0.9573 X ± 0.323 mm d-1, r2 = 0.7729 from august to november. The different time steps did not affect substantially the b value; but, in general, as the time step increased so did the mean error of the estimative due to the decrease in the number of points compared. Due to the operational difficulties in measuring ETo during periods of high intensity rains perhaps the relationships found for the second period represents better the degree of fit of the estimatives. The performance of the ETo estimatives did not change substantially when the measured net radiation was substituted by an estimative using the FAO-56 guidelines, simulating a very common situation of lack of such weather element.

A field research work was carried out to evaluate the FAO Penman- Monteith method, the constant watertable lysimeter and the Class A pan for estimating the reference evapotranspiration (ETo) as a function of the main climatic data (air temperature, relative humidity, wind speed and sunshine duration) obtained in a conventional meteorological station at Governador Dix- Sept Rosado county. A model for determining the class A pan coefficient (Kt) was also proposed for that location. The regression and path analysis were used in evaluating the direct and indirect effects from each collected climatic elements on estimated ETo rates. ln both analyses the reference evapotranspiration was the dependent variable (Y) and the climate elements were the independent variables (X). According to the results, the Penman- Monteith method showed a better adequacy in estimating the ETo rates from the climatic elements data either for dally values or flve days averaged values. For the five days averaged values the evapotranspiration measuring equipment showed a substantial improvement in the coefñcient of determination. The regression and path analysis showed similar results emphasizing that the sunshine duration is the main clímatic element in the evapotranspiration process either as direct or indirect effect. lt was observed that the Kt values for the study area was only 0.73. thus much |ess then 0.85 determined by FAO.
Este estudo teve como objetivo avaliar o método de Penman-Monteith (FAO). o lisímetro de lençol freático constante e o evaporímetro tanque Classe "A" na estimativa da evapotranspiração de referência (ETo), em função dos principais dados climáticos disponíveis (temperatura do ar à sombra, umidade relativa, velocidade do vento e número de horas de brilho solar) na estação meteorológica principal, instalada no município de Governador Dix-Sept Rosado. Foi proposto também um modelo para determinar o coeficiente de tanque (Kt) para o tanque Classe A". Para avaliar os efeitos direto e indireto de cada elemento climático na estimativas da ETo obtidas pelos diferentes métodos utilizou-se a análise de regressão e de trilha. Em ambas as análises a evapotranspiração de referência foi a variável dependente (Y) e os elementos climáticos as variáveis independentes (X). As variáveis estudadas foram provenientes de dados diários e médias de períodos de cinco dias. De acordo com os resultados, o método de Penman-Monteith (FAO) apresentou melhor coeficiente de correlação na análise de regressão quadrática com os elementos do clima, tanto para valores diários quanto para valores médios de cinco dias. Para os valores médios de cinco dias, os dados apresentaram substancial melhoria no coeficiente de determinação com os valores de ETo medidos pelos equipamentos. Pela análise regressão e de trilha os resultados foram semelhantes, comprovando que a duração do brilho solar diário é o principal elemento do clima no processo da evapotranspiração de referência, tanto como efeito direto quanto indireto. Observou-se que o Kt proposto para a região em estudo teve um coeficiente máximo de 0.73. muito inferior, portanto, ao valor recomendado pela FAO de 0,85.

Full textAbstract:
A maioria das aplicações envolvendo a influência do clima na agricultura requer um grande volume de dados que, geralmente, não estão disponíveis. Desta forma, há necessidade de um aplicativo computacional para facilitar a organização dos dados necessários. O sistema computacional SIAGRO foi desenvolvido para dar suporte a uma plataforma de coleta de dados termo-pluviométricos e para atender à demanda dos usuários da
informação agrometeorológica para agricultura. O sistema proposto permite, a partir de dados coletados a intervalos de 15 minutos, cadastrar outras estações, importar dados, calcular a evapotranspiração por diferentes modelos (Thornthwaite; Camargo; Thornthwaite modificado por Camargo e Hagreaves e
Samani), utilizar a classificação climática de Thornthwaite e determinar médias para os parâmetros coletados em períodos distintos de tempo. Os resultados são apresentados em
forma de gráficos e tabelas num computador pessoal ou via Internet, que podem ser exportados para uso em outros aplicativos computacionais ou comparados com os resultados de outras estações cadastradas no sistema. Disponibilizar o SIAGRO de informação que permita gerir de forma eficiente programas de
irrigação para atender as carências de água nos cultivos, permitiu que se avaliasse o desempenho de três métodos de referência para estimar a evapotranspiração com dados obtidos em lisímetros de lençol freático constante. Os dados foram coletados diariamente e processados em escala mensal. O desempenho dos métodos foi analisado a partir do coeficiente de correlação r e do índice de concordância de Willmot d. Os resultados mostraram que a melhor estimativa foi obtida com o modelo de Thornthwaite modificado por Camargo, devido ao seu melhor ajuste aos dados lisimétricos, apresentando uma concordância ótima, com índice d de 0,91.Since most of the applications involving the influence of climate in agriculture require a great amount of data that usually are unavailable, a computational tool is needed to help to organize the necessary data. The computational system SIAGRO was developed in an attempt to support such a demand of users of climate information in agriculture. The system makes it possible to register other stations, import climatic data, to calculate evapotranspiration by means of different methods (Thornthwaite; Camargo; Thornthwaite modified by Camargo and Hagreaves e Samani), to apply a climatic classification and to determine averages for different periods of time from daily data. The system presents its results in graphics and tables, which can be copied for use in other computer applications or used to be compared with results of other weather stations registered in this system. To supply SIAGRO with profitable information for irrigation scheduling and increase the efficiency in water use by crops, allowed the evaluation of three reference methods to estimating evapotranspiration through correlation with data obtained in constant water table lisimeter. The data were collected daily and processed in a monthly basis. The performance evaluations of the methods were based on the correlation coefficient r and Willmott agreement coefficient d. The results showed that the best estimate was obtained with the Thornthwaite modified by Camargo model, which shows the best adjustment to lysimeter data, with the index d equal to 0.91.

Extratropical cyclones are very important to define global climate. These systems are responsable for the heat transport to poles, preventing the continuous cooling of the extratropical region. The preferential areas of these baroclinic systems are called "Storm Tracks". Cyclones are directly associated to zonal and meridional air or surface temperature gradients. In this context, the variability and changes in the Storm Tracks behavior at present climate and in A1B for global warming scenario are investigated by using the coupled climate model ECHAM5/MPI-OM for the period between 1981 to 2000 (PD), and for global warming (GHG) for the period between 2081 to 2100. The results shows that the climate model used reproduces the variables and the distribuition of ST with reasonable consistency, when compared to the ERA-40 reanalises.It may be concluded that the path of extratropical cyclones delivered by the A1B scenario of global warming shows substantial modification in the sense that the ST moves southward in respect present day position demonstrates that variations in sea ice cover and sea surface temperature play the role heading in the magnitude and preferential area of cyclonic activity in the future climate scenario.
Os ciclones extratropicais são muito importantes para definir o clima global. Estes sistemas são responsáveis pelo transporte de calor para os pólos impedindo o arrefecimento contínuo da região. As áreas preferenciais destes sistemas baroclínicos são chamados de "Storm Tracks". Os ciclones são diretamente associados ao gradiente meridional e de temperatura. Neste contexto, a variabilidade e mudanças de comportamento dos Storm Tracks no clima atual e em um cenário de aquecimento global são investigadas por meio do modelo climático acoplado ECHAM5/MPI-OM no período entre 1981 a 2000 (PD) e para o aquecimento global (GHG) para o período entre 2081 para 2100. Os resultados mostram que o modelo climático usado reproduz as variáveis e a distribuição de ST com consistência razoável, quando comparado com o reanalises ERA-40. Os resultados para um cenário de aquecimento global A1B indicam que as trajetórias dos ciclones extratropicais sofrerão uma modificação na sua distribuição, deslocando-se mais ao Sul em direção ao pólo. Isso demonstra que as variações na cobertura de gelo marinho e da temperatura da superfície do mar foram determinantes na redistribuição da atividade ciclônica no cenário climático futuro.

Grid-type flight patterns at an altitude of 30 m were executed in the summer of 1991 by the Canadian Twin Otter flux research aircraft over a 15 km x 16.5 km agricultural area, as part of the San Joaquin Valley Air Quality Study/California Ozone Deposition Experiment (SJVAQS/CODE). Fast-response on board sensors for turbulence, temperature and gas concentrations permitted the spatial mapping of fluxes of momentum, sensible heat, moisture, CO$ sb2$ and ozone. Flux maps were produced in the form of GIS-interpolated 1 km averages, and in the discrete form of those coherent structures of the turbulent process, intermittent in time and space, which dominate the exchange of scalars between the ground and the atmosphere. The magnitude of surface-related mesoscale contributions to the flux was also quantified. Flux observations were compared against radiometrically observed surface temperatures and vegetation indices (NDVI), observed from aircraft and satellite (NOAA AVHRR), and surface characteristics from ground surveys.Flux maps showed the expected correspondence between greenness, evapo(trans)ration (ET) and CO$ sb2$ exchange. Discrepancies between ozone flux maps and maps of greenness, ET or CO$ sb2$ were more pronounced than would be consistent with the hypothesis of stomatal control of ozone uptake. More insight into control mechanisms on ozone exchange is gained by an examination of the spatial coincidence between transporting structures for the various scalars (heat, moisture, CO$ sb2$ and ozone), through the Jaccard coefficient of co-location (J), which showed a lower value ($ rm0.3

Para isso foram utilizados os dados do Censo Agropecuário (2006 ¿ IBGE): dados de quantidade produzida, área plantada, colhida para o período de 1990 a 2014, e séries históricas de precipitação para o período de 1974 a 2014. No tratamento dos dados da chuva elaborou-se a climatologia mensal, trimestral e anual, e se calculou um índice de seca (Standard Precipitation Index - SPI). Estas informações foram relacionadas com a quantidade produzida, área plantada e colhida dos cultivos. Finalmente se construíram calendários agrícolas para cada cultivo e município em estudo, que incluíram as informações mensais e decendiais. Os resultados mostraram que os municípios com 90% a 100 % de estabelecimentos familiares principalmente na área do Sertão Cearense detêm 40 % a 60 % de área agrícola total por município. Na análise da climatologia mensal dos municípios estudados, encontrou-se que os meses de maior total pluviométrico concentram-se entre fevereiro a abril devido à influência da Zona de Convergência Intertropical. Os municípios com máxima intensidade de chuva são Limoeiro do Norte, Aurora e Alto do Santo. A análise das tendências mostrou decréscimo das chuvas em todos os municípios para o período de 1974-2014. O índice de SPI destacou que os anos de seca associaram-se principalmente com eventos do El Niño, sendo estes mais intensos nos anos de 1990-1993 e 1997-1998, e houve uma relação direta com a diminuição da quantidade produzida de arroz no município de Aurora e Limoeiro do Norte, e do cultivo de milho em Acopiara. Os resultados dos calendários agrícolas de arroz, feijão e milho evidenciaram cada fase do cultivo para a melhor época do plantio em função do padrão mensal da chuva. Verificou-se que para cada localidade deve ser elaborado um calendário agrícola específico segundo o cultivo e o padrão mensal da chuva. Por esse motivo, foi sugerido que os municípios de Acopiara, Limoeiro do Norte e Tauá para os cultivos de feijão, arroz e milho respectivamente adiassem um mês a sua época de plantio. Este estudo pode auxiliar no aprimoramento das pesquisas sobre a chuva e sua influência na agricultura familiar no Ceará, servindo de base para uma melhor gestão de politicas públicas, de forma a otimizar a produtividade agrícola onde os ganhos sejam sentidos principalmente pelos agricultores familiares.
The objective of this study was to analyze the precipitation influence over the agricultural cultivation of corn, beans, and rice in the following six cities from the state of Ceará: Aurora, Alto do Santo, Canindé, Limoeiro do Norte, Acopiara, and Tauá. The information used was provided by the Farming Sense (IBGE-2006) and included: seeded and harvested area, and produced quantity from 1990 to 2014; historical precipitation series from 1974 to 2014. From the rain data manipulation it was elaborated the monthly, trimesterly, and annually climatology, where the SPI (Standard Precipitation Index) was calculated. This information was correlated with the seeded and harvested area, and produced quantity. Finally, agricultural calendars were created for each crop and city analyzed where rain information was available. The results showed that municipalities with 90% to 100% of domestic harvesting in the Sertão Cearense region detain 40% to 60% of the agricultural area. In the analysis of the monthly climatology of the scoped cities, the results also showed that from February to April the pluviometric indices were higher due to the influence of the Intertropical Convergency Zone. The cities with maximum rain density are: Limoeiro do Norte, Aurora, and Alto do Santo. The analysis of the rain density in the period of 1974 to 2014 exposed a decrease trend. The SPI showed that the drought periods were related with the El Niño, where it was more intense in the periods of 1990-1993 and 1997-1998, where a direct correlation was traced with the rice production in Aurora and Limoeiro do Norte, and corn production in Acopiara. The results of the agricultural calendars for rice, beans, and corn exposed the best match between the period of the year and each phase of the crops, based on the monthly rain standard. It was also verified that a specific agricultural calendar should be created for each locality, based on the crops phase and the local rain monthly standard. Due to this reason, it was suggested that the cities of Acopiara, Limoeiro do Norte e Tauá delay one month their seeding activity for beans, rice, and corn. This study can help in the improvement of the researches about the rain and its influence in the domestic harvesting in Ceará, serving as a base for a better management of the public politics aiming to optimize the agricultural production where gains can be granted especially to the domestic farmers.

Full textAbstract:
Lombardy is one of the most polluted regions at the European level, also due to its particular geographical structure and weather conditions which prevent the pollutants’ dispersion, and the high levels of emissions coming from human activities. Recently, some evidence has been found regarding the relationship between agriculture and air quality, particularly between ammonia - produced mainly by the livestock sector - and particulate matter concentrations. In this respect, Lombardy is the first Italian region for agriculture production, having 69% of its area classified as agricultural land and about 245 swine and 92 bovines per rural km2. In the Agriculture Impact On Italian Air project (AgrImOnIA, https://agrimonia.net, funded by Fondazione Cariplo within the framework of Data Science for science and society), we aim to predict continuously in space (i.e. mapping) air pollutants concentrations in Lombardy region, taking into account meteorology, land use and emissions coming from agriculture. In this regard, data integration and harmonization process have been carried out starting from data from different sources and characterized by different spatial and temporal resolutions. The first results are based on spatio-temporal Kriging models, with external drift, and an extension of the traditional random forest algorithm to consider the spatial and temporal correlation. These models will be used to generate scenario analysis which simulates the impact of policy interventions in the agricultural sector to mitigate its environmental impact on air quality.

Full textAbstract:
The planning of river basin management should utilize a high-resolution, process-based hydrological model to tackle issues such as diffuse pollution, drought, flood forecasting, and the impact of climate change. The studies available to date only encompass five meso-scale and one large-scale river basins in Ukraine. The objective of this study is to calibrate the Soil and Water Assessment Tool (SWAT) for all Ukrainian river basins, including upstream transboundary parts. The model could potentially assist in land management and assessing the impact of agriculture on water resources; hence, considerable attention is paid to agricultural practices and crop rotations. The Soil and Water Assessment Tool (SWAT) is a process-based semi-distributed hydrological model developed by the United States Department of Agriculture's Agricultural Research Service (USDA-ARS) in collaboration with numerous institutions. SWAT is widely used for simulating the impact of land management practices on water resources, including water quantity and quality, as well as assessing the overall environmental impact of land use and climate changes. The watershed, encompassing transboundary areas, covers an area of 873,600 km2, with Ukraine accounting for 68.7% of it. The inputs for the model consist of topography, river network, merged national soil maps with the properties for each soil polygon and underlying horizons, land cover, and agricultural practices such as crop rotations, fertilization, and operation schedules. In calibrating the model, we arranged daily discharge data from 56 gauges, snow cover from 61 locations, and crop yields of primary crops. The modeling period spans 41 years from 1980 to 2020. The modeling results are evaluated based on three criteria: the Nash-Sutcliffe coefficient (NS), the coefficient of determination (R2), and the percent bias (PBIAS). The model is available via a user-friendly web platform that features an interactive map of Ukrainian subbasins. Users can inspect the model inputs for each subbasin and monitor the daily dynamics of key outputs: river discharge, water flow components, evapotranspiration, soil water, and snow cover. The results can be downloaded as an image or a CSV file for further research. The hydrological model of Ukraine has the potential to address a wide range of issues related to water and agriculture: water supply, flood forecasting, soil water availability, water quality, the impact of climate change, and so on. The model will be expanded in the future to include sediment and nutrient transport.

Full textAbstract:
Abstract. On June 6, 2023, the Russian military blew up the Kakhovska HPP dam. During the day, large areas of the Kherson region and the nearest cities (Kherson and Oleshki) were flooded. In addition to flooding, this case led to the gradual draining of the Kakhovske reservoir, pollution of the Black Sea, restoration of the Dnipro riverbed, and the formation of a complex hydrological structure of medium and large reservoirs and watercourses. Methods. Multispectral satellite images were provided by the European Space Agency (Sentinel-2A). They used to separate areas flooded with water with a high degree of accuracy. Lower quality images from NASA's Terra, Aqua and NOAA-20 satellites were also used. Results. The surface area of the Kakhovske reservoir was 2,061 km2 before the destruction of the dam. 3 days after the breakthrough, approximately a quarter of the reservoir area (553 km2, 27.3%) was drained, mainly in the northeast. This is explained by shallower depths and the outflow of water downstream. The water intakes of large cities (Nikopol, Zaporizhzhia, Energodar), which are located within relatively shallow parts, have dried up. The water receded relatively evenly, the most on the left bank. On June 13th there were formed the separate reservoirs with an area of 200-400 km2 at the reservoir. The old bed of the Dnipro began to be restored. Water moved for 300 m from the city of Nikopol to the old channel. 15.06 observations were impossible due to cloud cover. On 18.06 the riverbed of the Dnipro River was restored. They began to form secondary watercourses that connected the Dnipro with the reservoirs from which the remaining water left. The reservoir stopped providing its economic and ecosystem services — water could not be obtained for drinking water supply, electricity generation, and irrigation. The water intake of the North Crimean Canal was exposed. This date can be considered the day of the termination of the Kakhovske reservoir. Its remaining area was 655 km2. As of June 20, the area of reservoirs was 509.3 km2, decreasing by 24%. The old channel of the Dnipro River is clearly distinguished. Numerous channels of small and medium watercourses were formed. The water level decreased by 10 m. On 21.06, the reservoir area decreased to 460.39 km2, after another 3 days it decreased by 165.25 km2 to 295.14 km2 (14.3%), i.e. by 50 km2 every day. The channel area was 123.73 km2, i.e. 6% of the reservoir area. June 25 area was 289.24 km2. On June 28, precipitation led to an increase in the area to 318.27 km2 (15.44%). Conclusion. We witnessed perhaps the world’s only unplanned draining of a large reservoir caused by a terrorist attack. The consequences are there: the drainage of the water intake of the North Crimean Canal will lead to the loss of productivity of part of agricultural land. Most of the remaining water basins will dry up, except of the lakes formed as a result of draining Kakhovske reservoir. Water from them is drained by a system of small watercourses that will follow each other until vegetation appears. After they dry up, the area of the reservoir will decrease by about 6% compared to the initial area. It is not yet known what scenario will be chosen to restore the Kakhovske reservoir. One of the initiatives involves the transfer of plots to agricultural production. Their area on the right bank is 72,701.1 hectares, and on the left — 116,192.3 hectares, respectively — the latter are not yet available for use due to invasion.

Full textAbstract:
The southern part of Ukraine is one of the most vulnerable regions of the country to climate change due to the increasing precipitation deficit. The region is highly dependent on a system of canals fed with water from the Kakhovka reservoir. The Kakhovka Dam destruction on June 6, 2023 and the consequent disappearance of the reservoir led to water supply problems to many settlements and agricultural lands. Rainwater harvesting in a precipitation-deficient region is an important measure for climate change adaptation. One of the solutions to mitigate the consequences of technical water deficit at the individual household level is an installation of rooftop rainwater harvesting systems (RRWHS). To evaluate the feasibility of using such systems and estimate the amount of water potentially collected, simulations are performed based on both climatological and climate projections data. Various indicators can be used to evaluate the RRWHS efficiency, e.g. volume of water that can be collected (precipitation inflow PI index) or the amount of time with a shortage of water in the water storage (demand exceeds supply, DES index) for a given roof area, the roof and the water storage geometry and average water consumption. The essence of the DES index is the time in days when water demand exceeds the actual water supply to the RRWHS water storage. The DES calculation involves solving the water balance equation as described in [1]. The water level change component of the equation takes into account runoff coefficient (depends on the roof geometry), the roof area, actual precipitation during a day, water outflow (daily water demand), daily evaporation rate and an area of the water storage [1]. When solving the water balance equation, the condition of not exceeding the actual water storage volume must be met. The E-OBSv27.0e dataset [2] was used as input data on precipitation over the period 1991-2020. The results of DES and PI simulations were obtained for the roof area of 50, 75, 100 m2 under the condition of the runoff coefficient equal to 0.75. The results were obtained for a fixed daily water demand of 0.3 m3 and the water storage volume of 2.0 m3. For climatological assessment, the daily DES data in the southern region of Ukraine were averaged over months, seasons and the whole climatological period. Since the efficiency of RRWHS depends on the roof area, for practical purposes PI index per 1 m2 of the collection area was calculated as well. The simulation code has been adapted to use both GFS and WRF forecast data as an input. Thus, it can be used for operational forecasting of the water level in the water storage of preset parameters in different sites of the Southern region of Ukraine.

Full textAbstract:
The field of nature management is an important component of the national economic complex. The state controls the use of natural resources and the preservation of the environment. Existing environmental problems related to the use of resources are secondary to the priorities of state economic policy. The most disincentive influence on the dynamics of natural resource attraction and environmental protection is exerted by the institutional irregularity of resource use monitoring processes. This is related to the lack of an effective system of natural resource inventories, the inequality of different forms of ownership of natural resources, and the dualistic nature of the system of management and regulation of natural resources. It should also be pointed out the asymmetry of the system of fiscal regulation and inter-budgetary relations regarding the distribution of resource payments and environmental fees. The influence of environmental factors on the economy is obvious: the economy as a sphere of material production directly depends on the resource base, territorial features and natural raw materials. The quality and quantity of resources and raw materials determine the possibilities and limits of economic growth. Global and local ecological systems are characterized by appropriate resistance to external and internal influences. Possible manifestations of survival under adverse conditions, cyclical and rhythmic processes, balance of natural processes. But these manifestations have certain limits. Certain types of activities can quickly cause changes in the state of natural components and affect the effectiveness of activities. Thus, industrial pollution of the atmosphere in a number of cases leads to crop losses of agricultural products. Discharges of pollutants into water sources reduce fish productivity, etc. Such consequences have the character of external effects in relation to activities that are a source of negative changes in the state of the environment. External effects are not taken into account first, but they significantly affect economic results. Quite often, external costs are difficult to estimate. As a rule, they are costs for society, and in some cases for future generations. Environmental problems cause situations when the economic value of ecological resources is not reflected in the price. This is the main thing for the economy of nature use. The state should play a significant role in the regulation of nature management processes. One of the possibilities of ensuring the resource potential of further development was proposed as a model of the interaction of five main factors: population, natural resources, food, capital, environment. The method of economic-mathematical modeling was used, which was called "intersectoral balance" and took into account the requirements of environmental protection. The results of economic activity - generation of production waste and costs associated with their disposal - were introduced to the existing "costs - output" model.

Full textAbstract:
Weather measurement systems became an important tool for the ef- ficient operation of various economic activities. Automated irrigation systems, that improve agricultural productivity and reduce the consumption of water resources, relies on data collected by these systems, for example. Due to the inherent complexity of these systems (i.e. stations with multiple sensors communicating through multiple communication channels to cloud services), it is very important to have measures that clarify how faults behave allowing better planning of maintenance and establish a degree of systems reliability. This work presents a study of the availability of all meteorological stations of the National Institute of Meteorology-INMET installed in the Brazilian territory in the year 2017. The results present the first analysis of this parameter and serve both for academic and commercial users, as a form of measurement of these systems reliability, as well as for weather measurement infrastructure providers as a tool for improving the effectiveness of their maintenance policy and as a support for the strategic planning of new investments.

In International Conference of Young Scientists on Meteorology, Hydrology and Environmental Monitoring. Ukrainian Hydrometeorological Institute, 2023. http://dx.doi.org/10.15407/icys-mhem.2023.016.
Full textAbstract:
The left tributaries of the Middle Dnipro - Psel, Vorskla, Sula, Trubyzh, Supii, Zolotonoshka, Kryva Ruda, Kobelyachok, Kagamlyk, Irkliy, Kovray and Kovalivka belong to the category of medium and small rivers. These rivers are important for the left-bank forest-steppe of Ukraine, where they flow. They are used for irrigation of agricultural land and for hydropower. Global climate change in the region and the introduction of green electricity in Ukraine, these two aspects are currently very important for two reasons. The total flow volume of the rivers of the left bank of the Middle Dnipro subbasin is similar to the flow volume of the Southern Bug, and the catchment area is even larger. The three largest rivers of the region, Psel, Vorskla and Sula, are particularly promising in this aspect. Today, small hydroelectric power plants only operate on the Psel and Vorskla rivers. All hydroelectric power plants are located in the middle course of the river: on the Psel - within the boundaries of Sumy and Poltava regions, and on Vorskla - within the boundaries of the Poltava region. The left bank of the Middle Dnipro has 15 small hydros operating today, with 10 of them on the Psel and 5 on the Vorskla. River Psel, from the village of Nyzy in the Sumy region to the village Sukhorabivka fish of Poltava region, fully regulated. The following small hydropower plants operate on Psel: Nyizivska, Vorozhblyanska, Mykhailivska, Bobrivska, Knyshivska, Veliko-Sorochynska, Shishatska, Velika Bagachka, Ostapievska and Sukhorabivska. The total annual electricity generated is 4.78 MW. Upon the completion of its planned operation by 2025 as planned in the plan for the development of hydroelectric power plants, the Malobudyshchanska hydroelectric power plant is scheduled to be functional. 5 small hydroelectric power stations operate within the Vorskla riverbed and its left tributary – the Vilshanka – Opishnyanska, Vakulynska mini hydro, Poltava Hydro mini hydro, Nizhnyomlinska and Kuntsivska. The Vorskla river from the village of Kuzemin in southern Sumy Oblast to the village of Kunzevo in Poltava Oblast is regulated by regulating locks and small hydrographic locks. These locks are located in the villages of Kuzemin (Sumy Region) and Derevky (Poltava Region). Both systems are included in the development plans of their regions until 2025, within which 2 small hydroelectric power plants will operate. A total of 1.72 MW of small hydropower is generated within the Vorskla Basin. The power of hydroelectric power stations on both rivers ranges from 0.19 MW to 1.04 MW - Shyshatska small hydroelectric power station. Global climate changes also affected the Left Bank-Dnipro hydrological region. Over the past 30 years, the average annual air temperature has increased by 1.5-2 0C and the annual precipitation has decreased by 20-30 mm. The most significant changes are seen in the southern, southwestern, and eastern parts of the left bank of the Middle Dnipro, especially in the small river basins of the Dnipro Lowlands and the lower reaches of the Sula, Psel and Vorskla rivers. Therefore, these regions need irrigation systems functioning within their river basins. The left bank of the middle Dnipro River basin has a total of 26 irrigation systems covering a total area of 65,000 hectares. The largest number of irrigation systems is in the Dnipro Lowland river basin:13 irrigation systems (12,000 ha) on the left bankin Cherkasy Oblast,11 irrigation systems (50,000 ha) in Poltava Oblast, and 2 irrigation systems (up to 3,000 ha) in Kharkov Oblast. Thus, the left bank of the middle Dnipro river has great potential for hydropower and water quality improvement. The total capacity of small hydropower plants in the Psel and Vorskla river basins is 6.5 MW, which is about 6.37% of the total capacity of small hydropower plants in Ukraine (in 2019: 102 MW for Ukraine). The use of small hydroelectric power stations on Vorskla and Psel is quite promising for Poltava and Sumy regions for local consumption and the growth of the share of green energy in these regions. As for irrigation systems, in general, 32% of the total irrigated area in the Dnipro basin (196,000 ha) is concentrated on the left bank of the middle Dnipro river.
