This working paper presents a proposal to quantify the Net Primary Productivity (NPP) of crops, pastures, and forests within an Andean and tropical context. The methodology is based on the adaptation of Agrarian Metabolism for the case of Ecuador. The following sections provide the necessary information to estimate each land use, including the sources used, the calculations, and the required coefficients, which are detailed in the Annex. These conversion factors are adapted to the country's conditions to account for the real NPP of ecosystems and agroecosystems, which involves quantifying the total phytomass, both harvested and non-harvested, of aboveground and root parts. The methodology can be useful for similar for similar cases where official data sources may be limited, especially for the NPP of pastures and forests. Furthermore, it can be applied to both contemporary and historical studies, as it considers the transition from organic-based agriculture to an industrialized model. This is exemplified at the end of the document with the main results of the case study ​
