The rights of nature have been widely discussed at a philosophical level for a long time, but examples of its practical application are quite rare. Ecuador is the first country to incorporate this concept into its constitutional foundation and put the theory into practice. However, implementing entirely justifiable rights of nature is hindered by factors, such as economic considerations, legal interpretations, cultural norms, political will, and disproportionate perspectives of “the greater good”. After getting opp [...]

Current production and distribution models in agriculture primarily operate based on the 'linear economy' approach. This means that after the exploitation of natural resources and the production of the final product, a significant portion of these resources and products, now contaminated or turned into waste, exit the economic cycle. The circular economy approach in agriculture seeks to reuse waste products and depleted inputs, thereby reducing the intensity of resource exploitation and taking a step towards sustai [...]
