As a solution to mitigate the effects of climate change, scientists have been looking for more environmentally friendly energy production alternatives, so, since the 2000s, renewable energy production has increased across Europe. Climate change has a negative impact on our planet, with increased emissions of greenhouse gases contributing to global warming. In this context, biogas has become a promising solution for reducing greenhouse gas emissions and improving environmental quality. The purpose of the study is to review the evolution of research and development in this field, identify trends and gaps in existing knowledge, and assess the impact and significance of published research. In this sense, a bibliometric analysis was carried out, based on the topics "renewable energy" and "biogas", in which VosViewer software was used to create maps. The research results show that existing policies worldwide encourage transfer and synergy between researchers from different countries, achieving important results. Practically, researches and examples of good practise show that biogas can be a viable solution to mitigate the effects of climate change, and in the coming decades, under the conditions of the population growth estimates materialization, we will most likely witness an intensification of agriculture to ensure the population's food needs.

In front of escalating resource limitations in agriculture, this study emphasizes the critical need for efficient crop cultivation. Focusing particularly on tomatoes, a staple in global diets, the research aims to sustenably enhance productivity. Recognizing productivity as a key economic indicator, the study highlights the pivotal role of energyefficient practices in addressing challenges posed by climate change and depleting natural resources. By optimizing energy use in agricultural processes, this research not only improves economic efficiency but also positions the sector for resilience and innovation in a resource-constrained environment. Through an in-depth analysis of data from Eurostat covering the 2014-2022 period, we trace the trends in greenhouse tomato cultivation across Europe, evaluating changes in cultivation areas and productivity. This research offers insights into how different European countries have adapted their agricultural practices in response to environmental and economic pressures and in the same time, it underscores the need for continued innovation and adaptation in agricultural practices to meet the demands of a growing global population under increasingly constrained environmental conditions.

Charcoal rot of the sunflower roots and stems is present worldwide in all the areas with arid climate where is determining major loses. The etiologic agent of this disease is the fungus Macrophomina phaseolina considered as invasive due to its great range of host plants (over 500 species) and the very high harvest loses of the cultivated crops, mostly sunflower. The present climate changes are favouring the spread of the disease in areas where it wasn't present before. The climatic simulations realised until now in Europe shows the adaptation trend of the fungus in areas from Central and Southern Europe. The survival of the pathogen Macrophomina phaseolina in soil for long time periods makes its control almost impossible. In this work it was brought to attention the state of the art of the researches regarding the symptomatology, pathogeny, epidemiology and the control of this pathogen in conjunction with the climate change. The control strategies should highlight the prevention methods and the biological ones and less attention to be addressed to the chemical ones. The fungal and bacterial agents can be in future a viable alternative for the control of the pathogen M. phaseolina. [ABSTRACT FROM AUTHOR]
