Climate change, global warming are phenomena that have changed the face of the world and that have a direct impact on agricultural production and food security, given that the world's population is growing from one year to the next, without the possibility of growth and natural resources. Another worrying phenomenon is the production of greenhouse gases and their destructive effect on the planet. That's why the technology that is being perfected every day tries to find solutions that simplify both the efforts made to obtain food, but also the possibility of increasing the efficiency of production processes. In this way, in the agricultural field, the idea of developing dual systems appeared, which would protect both agricultural crops, with the aim of increasing productivity, but which would also contribute to obtaining solar energy, necessary not only for own consumption, but also to be included in consumer networks, the proposed concept being that of the AgriVoltaic system. The idea that appeared in 1981 began to be developed, currently reaching the development of a technology that is starting to be adopted in many countries of the world, including Romania. In the current paper, we propose to analyze the opportunity of using AgriVoltaic technology, its advantages and disadvantages, but also the way in which it could contribute to increasing the profitability of agricultural farms. At the same time, increasing the degree of awareness regarding the advantages of introducing agricultural systems and the method of implementing the systems is another objective of the current work. Starting from the analysis of the specialized literature, we outlined the term Agrivoltaic technology and continued the study with an analysis of the possibilities of implementing this technology in Romania, due to the solar energy potential that it benefits from. The research methodology assumed on the one hand the bibliographic analysis, and on the other hand the analysis of the development potential of the system, taking into account the existing agricultural areas and crops suitable for this system. As a result of the research carried out, it turned out that although there are confirmed advantages of using AgriVoltaic technology, it does not yet benefit from sufficient visibility or high accessibility among farmers. Also, the existing legislation at the level of Romania does not yet make possible the development of the dual system. Among the disadvantages of using agrivoltaic systems are the still high costs, but the measures to protect the rural landscape, which occupies an important place in sustainable development, even if the energy produced is renewable.

The paper emphasizes the importance of subsidizing agricultural activities, taking into account the climate changes that are more and more evident making agricultural holdings particularly vulnerable from an economic point of view, the most exposed being the small ones. The technical-economic the economic-financial analysis methods drew a technical-economic diagnosis of a small-scale vegetable farm in Romania, in order to highlight the major impact that subsidies have in achieving incomes that ensure the continuity of the activity. The vegetable farm under study was established in 2018, being included in the category of micro-enterprises paying income tax. It owns agricultural land exclusively on lease, the existing crops being those of wheat, corn, alfalfa, bell peppers and melons, with average productions/ha achieved similar to or below the average productions/ha recorded at national, regional and county level. From an economic and financial point of view, this holding presents a financial instability during the analysis period, based on the losses recorded in 2018 and 2020 and a non-compliant financial autonomy based on insufficient equity capital. It does not have the ability to generate constant profit during the period included in the study by capitalizing on production, it being small and insufficient, which denotes the major dependence on the income from exploitation subsidies in order to be profitable. Liquidity indicators evolve fluctuating and solvency is generally downward and positioned above the safety threshold, which places small-scale vegetable farms at risk of insolvency.

The paper purpose was to assess the impact of climate change on wheat, maize and sunflower yield in the period 2017-2021, using statistical data from National Institute of Statistics (NIS) and National Administration of Meteorology (NAM) and other sources. Comparison method was used to evaluate the deviations between the registered air temperatures and precipitations and the 1981-2010 climatological norm. Graphic method reflected the dynamics of monthly air temperatures and rainfalls in each year. Descriptive statistics for mean, standard deviation and coefficient of variation reflected an more comprehensive image upon air temperature, precipitations and yield. Correlations and regression equations were used to establish the intensity of the kinks between climate factors and yield. The highest average air temperature In Romania was 12.130C in 2019. In the period 2017-2020, the average annual temperatures exceeded the climatological norm 1981-2010 accounting for 9.10C. The lowest rainfalls, 614.2 mm, were recorded in 2019, being below of 633.1 mm the norm for the period 1981-2010. The high temperatures associated with drought and low precipitations have deeply affected yield of many agricultural crops, including maize, wheat and sunflower. The highest wheat yield 4,888 kg/ha was achieved in 2017, and the lowest one, 2,966 kg/ha in 2020. Maize registered the highest performance of 7,644 kg/ha in 2018, and the lowest one, 3,977 kg/ha in 2020. Sunflower carried out the high performance 3,041 kg/ha in 2018, and the lowest one, 1,858 kg/ha in 2020. The worst agricultural years for these three crops was 2020, but 2017 favored wheat, while 2018 favored maize and sunflower. The correlation coefficient had in general small values between average temperature and yield, but a higher link with precipitations level. The multiple correlation between yield, air temperatures and precipitations was: r= 0.817 for wheat, r = 0.116 for maize and r = 0.504 for sunflower. In the South Eastern Dobrogea, the driest area in Romania, the rainfalls declined by 65% in the period 2018-2020 having a deep negative impact on sunflower seeds yield, which decreased from 4,282 kg/ha in 2018, to 1,503 kg/ha in 2020. The correlation between precipitations and sunflower yield positive and very strong (r = 0.737). As a conclusion, the climate conditions should be analyzed in each farm and farmers have to take measure to adapt the technologies for sustaining production. [ABSTRACT FROM AUTHOR]

Agriculture is the one of the most important priorities and economic activities in developing countries. Climate change, which is already affecting the society at a global level, has an impact on the increase in magnitude and frequency of severe weather events. As such, both agriculture and industry are affected by climate change and their revenues decrease, thus affecting the entire economic cycle. The aim of this paper is to present theoretical considerations regarding climate change induced severe weather events and to highlight some practical techniques used in operational meteorology in order to improve the forecast of severe weather events. By analysing the morphology and dynamics of thunderstorms, by applying the correct parametrization in weather forecast models, nowcasting and by issuing on time weather alerts, financial losses may be limited. Throughout this paper, the parametrization of convective cells will be described, operational forecasting techniques will be presented and the application of ingredient-based forecasting methodology will be discussed. Severe weather associated hazards like hail, heavy rainfall, damaging winds and even frost will be analysed in order to establish a local climatology of these phenomena. With the aid of Weather Surveillance Doppler Radar (WSDR) and by associating some instability convection indices with synoptic charts, the agriculture-related severe weather events can be identified and their formation pattern can be established. Further on, by establishing an analysis methodology and by compelling all available data, weather-related hazard maps are to be compelled and are to be used by agrometeorology forecasters in order to seek viable solutions. The Western part of Romania is characterized as having a moderatecontinental climate, with hot influences from the Southern part of Europe and with humid advections from the South-Western part of Europe. In combination with cold advections from the Northern Europe, both summer as well as winter specific agriculture-related severe weather events are present [ABSTRACT FROM AUTHOR]

Crop management in the Romanian agriculture faces many risks and challenges that directly influence the technical and economic performance of the farms and implicitly the sustainability of the agricultural sector. These challenges range from climate change to resource issues, from plant health problems to market and regulatory issues. It is therefore essential to understand these issues in detail to develop effective crop management strategies and support Romanian agriculture in the face of a complex and changing environment. Through methods of statistical analyses and bibliographic documentation, we will identify and analyze this risks and challenges in detail in order to obtain a more comprehensive picture of the agricultural landscape in Romania in order to develop some necessary measures to reduce and, as far as possible, eliminate these risks. Data were collected from public institutions, from the official National Institute of Statistics, NIS, website Tempo-Online. The aim of crop management in Romania, as in any other country, is to ensure efficient, sustainable and profitable agricultural production. By adopting these recommendations and proactively addressing risks and challenges, agriculture in Romania can become more resilient and sustainable, further ensuring the supply of high-quality food and contributing to the country's economic development.

The paper aims to assess the pollution level of Romania's agriculture, with emphasis on emissions of carbon gases, by analyzing the structure, trends and estimates of indicators projected in medium and long terms, according to the actual policies and targets for moving to a competitive low carbon economy in 2050. Romanian agriculture has not proved to be very intensive in terms of greenhouse gases pollution compared to the energy sector, however, being the second pollutant sector of economy, is one factor that contributes significantly to overall emissions mainly due to emissions of the livestock sector and of synthetic fertilizers use. Analysis shows potentials in 'greening' the economy in Romania, given the trends of massive reduces of emissions of greenhouse gases over the last two decades. It also underlines the crucial importance to reduce the statistics on polluting effects of agriculture provided by the potential expressed and growing of the Romanian forestry sector.

It is well known that farming has always been risky. The income obtained in agriculture may differ from year to year because of its dependence on the climatic and soil conditions and because of the output prices. Also, the taxation has an influence too on the income, too. Although, both Romania and the United Kingdom are member states of the European Union, the taxation varies, so, the point of this study is to show the differences between the taxes applied on annual income in agriculture in this two countries, attempting to discover recommendations for a better performance, where needed. The conclusions drawn will reveal which agricultural system is more efficient, but also the benefits for the farmers from the both countries. [ABSTRACT FROM AUTHOR]
