Application of Geospatial Techniques in Agricultural Resource Management
Although technological advancements have sparked the beginning of the fourth agricultural revolution, human beings are still facing severe problems such as shrinking croplands, dwindling water supplies, negative consequences of climate change, and so on in achieving agricultural resilience to meet the demands of the growing population over the globe. Geospatial techniques involving the integrated use of geographic information system (GIS), remote sensing (RS), and artificial intelligence (AI) provide a strong basis for sustainable management of agricultural resources aimed at increased agricultural production. In recent times, these advanced tools have been increasingly used in agricultural production at local, regional, and global levels. This chapter focuses on the widespread application of geospatial techniques for agricultural resource management by monitoring crop growth and yield forecasting, crop disease and pest infestation, land use and land cover mapping, flood monitoring, and water resource management. Moreover, we also discuss various methodologies involved in monitoring and mapping abovementioned agricultural resources. This chapter will provide deep insight into the available literature on the use of geospatial techniques in the monitoring and management of agricultural resources. Moreover, it will be helpful for scientists to develop integrated methodologies focused on exploring satellite data for sustainable management of agricultural resources.

Green Adsorbents for Water Purification
Water purification is crucial for ensuring access to safe and clean drinking water. As a sustainable and effective solution, green adsorbents have gained significant attention in recent times. These adsorbents are composed of natural or waste-based materials that are biodegradable, renewable, and abundant, making them an eco-friendly substitute for traditional adsorbents. This chapter offers a comprehensive outline of the present and prospects of green adsorbents in water purification. It encompasses a comprehensive overview of the many forms of green adsorption agents comprising natural, agriculture waste-based, & industrial waste-based adsorbents, as well as their synthesis and modification methods. Furthermore, it also explores the potential applications of green adsorbents in removing heavy metals, organic pollutants, and inorganic contaminants from water. The challenges and future directions of green adsorbent research are also discussed, including the limitations of these adsorbents and the opportunities for enhancing their performance. Overall, this chapter offers valuable insights into the potential of green adsorbents as a sustainable and eco-friendly solution for water purification.
