Global-scale diffusion of IR refers to the spread of ideas, technologies, or practices across multiple countries or regions.
Local-scale of IR diffusion, on the other hand, refers to the spread of ideas, technologies, or practices within a specific community or region.
While global-scale diffusion can lead to the rapid adoption of new ideas, it may also face resistance from local cultures and traditions.
Local-scale of diffusion, on the other hand, can be more effective in promoting long-term change and sustainable development within a community.
