Climate models have become an important tool in understanding as well as projecting future climate conditions. They thus become very critical to decision-making processes, especially in mitigation and adaptation strategies. This paper provides a general overview of methodologies that are applied in climate modeling, its validation, and uncertainty mapping, notably their strengths, limitations, and challenges. The paper takes the reader through all the intricacies associated with the modeling of climate systems: global circulation models, regional climate models, and statistical downscaling. Much emphasis is given to the issue of model choice depending on the research objectives and spatial scales. Thorough model validation is considered, emphasizing that observational data forms the core and good quality and availability are issues. Climate modeling should incorporate uncertainty quantification as a core activity. This paper debates estimation and representation techniques of model uncertainties applied, such as probabilistic approaches, sensitivity analysis, and ensemble modeling. Introduce an idea called here uncertainty mapping, as a means of communicating the climate-related risks. This paper sets this tone by asserting that uncertainties in climate modeling have to be communicated as clearly as possible to decision-makers. No matter how intrinsically complex and limited they are, climate models represent, by themselves, very valuable means for the task of estimating the probable futures of climates. This quest ranges from enhancing model accuracy to ever-lowering estimates of uncertainties, all impelled by new advances made in computational powers and deeper insights into the climate systems.

Ethnoveterinary practices, particularly the use of wild medicinal plants, play a significant role in animal healthcare in many rural communities of Malawi, Rwanda, and Ethiopia. These traditional practices provide affordable and culturally relevant alternatives to conventional veterinary medicine, especially where access to modern animal healthcare is limited. However, despite their potential, limited documentation and systematic evaluation of these practices pose challenges for their integration into broader animal health strategies and conservation efforts. This critical review aims to synthesize available knowledge on wild medicinal plants used in ethnoveterinary medicine across the three countries, focusing on plant species, preparation methods, dosage, and efficacy. The methodology involved a comprehensive literature search of peer-reviewed articles using databases such as PubMed, Scopus, and Web of Science. Inclusion criteria were applied to identify studies documenting traditional uses, plant preparation, dosage, and efficacy. Data extraction focused on key plant species, ethnoveterinary applications, preparation techniques, and reported effectiveness. Findings reveal a diverse range of wild plants utilized for treating various animal health issues, such as gastrointestinal disorders, wounds, and parasitic infections. Preparation methods often include decoctions, infusions, and topical applications. While many plants are reputed to have high efficacy, scientific validation remains limited for many species. The review underscores the need for further pharmacological studies and policy measures to protect traditional knowledge and biodiversity. This study highlights the critical role of ethnoveterinary practices in enhancing animal health and emphasizes the need to integrate traditional and modern approaches, promoting conservation and sustainable utilization of wild medicinal plant resources.

The object of the research was to determine the adverse effects of different concentrations of nickel chloride and cobalt chloride (10, 20, and 30) mg/L for a month on the physiological characteristics of Myriophyllum verticillatum and Schoenoplectus litoralis as well as assess the concentration of total chlorophyll and protein content. The results of the study showed that the concentrations of the components increased at the end of the investigation in the water plants used for the examination as compared with the control sample, in addition to a decrease in the protein and chlorophyll levels of the water plants exposed to the effects of heavy metal.

Previous studies have reported a positive influence of zirconium oxide nanoparticles on plants, the present effort was conducted to investigate the impact of two distinct concentrations of biosynthesized zirconium oxide nanoparticles (75 and 150 mg L-1) on the physiological and antioxidant responses of Vicia faba Plants. Zirconium oxide nanoparticles (ZrO2NPs) were synthesized using Matricaria chamomilla L. plant extracts. And their morphology and extent were determined Using X-Ray Diffraction and Transmission electron microscopy The diffuse reflectance spectra were measured using UV-Vis spectroscopy, the response of V. faba plants to foliar sprays regarding concentrations of (0, 75 and 150 Mg / l-1) M-ZrO2NPs was studied. The largest concentrations of chlorophyll a and b, carotenoids. Total pigments were documented in plants receiving 75mg / l-1 of M-ZrO2NPs associated to the control, secondary metabolite (Phenolics, Flavonoids, and Tannins) were gathered in response to M-ZrO2NPs treatment Glycosides, Terpenoid, Alkaloids (Mayer reagent) and Fuocoumarins. Moreover Tannins, Resins and Saponins, in addition to the levels of enzymatic and non-enzymatic antioxidants, rose by about two-fold in plant exposed to M-ZrO2NPs compared to control plants. The nitrogen, phosphorus, the contents of bean plants in terms also potassium, calcium, zinc, iron were noted in response to two applied quantities of M-ZrO2NPs. Spraying shrubberies by 75 Mg /l-1 of M-ZrO2NPs promoted plant development in addition to the buildup of antioxidants, osmolytes, and secondary metabolites that can help plants cope with the harmful consequences of environmental stress.
