## 5 Conclusions  
Understanding the changes in ESs and their relationship with the help of spatially explicit methods could be helpful for the study to be conducted. In the present review, research dynamics of ES in the global scenario are given, and are then narrowed down to the national scale of the Indian scenario between 2000 and 2021. This analysis is based on 138 articles gathered from the databases of Science Direct, etc., with the help of bibliometric statistics such as keywords, countries, and outcomes. Additionally, ecosystem types, geographical location of the studies conducted, and assessment and valuation methods are in the limelight. The number of publications in the Indian context is gradually increasing. We find a steady increase in the publication trend post-2015. We find publications focusing on the study of two or more ES categories. Crop production and water yield have focused on provisioning ecosystem services; carbon sequestration, soil conservation for regulating ecosystem services; biodiversity conservation, along with the nutrient cycle, for supporting ecosystem services; psychological behavior, and quality of life in cultural ecosystems. We find these studies have been completed, since these are considered major determinants ruling these ESs along with the help of readily available research methodological framework. On the other hand, due to lack of methods and data, it is difficult to map the remaining ESs. In the Indian context, water, carbon, and soil play a major role in improving the socioeconomical aspect of ES.  
India is a peninsular country with a wide variety of physical landscapes, including croplands, woods, grasslands, deserts, rivers, lakes, deltas, shelves, oceans, mountains, plateaus, basins, and islands. With its existing rapid economic growth and massive urbanization, India has become increasingly vulnerable to both natural disasters, such as droughs and floods, and human-caused ecological disasters, such as deforestation, salinization, erosion, and water, air, and soil pollution. The ES transdisciplinary paradigm serves as a useful framework for analyzing diversified natural assets and addressing environmental issues through integrated ecosystem management. However, the dataset built in this review work is not comprehensive; it can serve as a foundation for future studies, with the hope of creating a complete ES research database at the national level.
