The ability to produce high-resolution climate maps is crucial for assessing change impacts and mitigating disasters risks in developing countries. Mainstream geostatistical downscaling techniques use spatial interpolation or multi-linear regression models data-scarce regions. Since global evolution a nonlinear process governed by complex physical principles, these linear cannot achieve the desired accuracy. Moreover, utilize different resolution data as model inputs. In this study, we...
Climate change poses a global challenge with profound impacts on diverse aspects of the environment and human society. Understanding these is crucial for formulating effective mitigation strategies. As one most critical threats to sustainable development, climate anticipated affect environment, health, food security, economic activities, natural resources physical infrastructure. This review focuses change, its consequences efforts in Ethiopia. Ethiopia has encountered both variability...
This paper proposes and analyses a basic deterministic mathematical model to investigate Simulation for controlling the spread of malaria Diseases Transmission dynamics. The has seven non-linear differential equations which describe control with two state variables mosquito’s populations five human’s population. To represent classification human population we have included protection treatment compartments SIR epidemic extended it SPITR introduce new modified by adding vaccination...
This paper proposes and analyses a basic deterministic mathematical model to investigate Modeling Analysis of effect awareness program by media on the spread COVID-19 Pandemic Disease. The has seven non-linear differential equations, which describe effects programs diseases. Analytical study carried out analysis existence stability system, given threshold parameters known as reproduction number, obtained using next generation matrix method. equilibrium COVID 19 models is determined. In...
The occurrence of extreme precipitation events always leads to a mass disasters. In this study, based on daily data from 20 meteorological stations in Ethiopia, we performed detailed analysis patterns and trends ten indices during 1990–2020. Our study revealed that different topographic conditions the Ethiopian Plateau, savanna desert resulted great differences precipitation. Notably, intensity (Rx1day, Rx5day, SDII) amount (R95pTOT) showed significant downward eastern (averagely −1.0...
One of the most serious challenges in world is climate change. This study examines variations seasonal and yearly fluctuations extreme temperatures precipitation Ethiopia from 1987 to 2020 using 36 meteorological stations located various climatic zones. The outcomes demonstrated increased trends average annual maximum minimum temperatures, with values 0.094 ∘ C 0.052 C, respectively. Despite falling summer, experienced higher winter than summer. Furthermore, analysis revealed a trend toward...
This paper proposes and analyses a basic deterministic mathematical model to investigate Modeling Analysis of effect awareness program by media on the spread COVID-19 Pandemic Disease. The has four non-linear differential equations, which describe effects programs diseases such as flu been proposed analyzed. In modeling process assumed that disease spreads due contact between susceptible infective only. growth rate influencing population be proportional number individuals. It further, media,...
