Agroforestry modeling for natural resource management
(Elsevier, 2023) Arnab Banerjee; Manoj Kumar Jhariya; Abhishek Raj; Bhimappa Honnappa Kittur; Ram Swaroop Meena; Taher Mechergui
Agroforestry (AF) is an integrated system involving tree–crop interaction to improve the agroecosystem's overall health and address food security. Simulation modeling is an approach that aims toward improving the AF output across various countries. AF practices tend to enhance the economic output of the farming system in comparison to the traditional farming system. Further, additional benefits include the regulation of proper biogeochemical cycling through various forms of physiological processes. Simulation modeling across various countries has shown significant promise toward improving the effectiveness of AF practices. Various forms of environmental mega events in terms of climatic perturbations, happenings of climatic extremes, biodiversity loss, and increasing human population pressure promote nature's contribution to mankind. Various models have been used to predict the contribution of the AF. A review of existing models revealed a major focus on biomass production and yield. Further upgradation in the form of the availability of codes, and a model having a more public domain, helps to understand the multiple interactions between the tree–crop system and overall implication both in the structure and process of resource management is required. © 2024 Elsevier Inc.

Climate Change Vulnerability and Agroecosystem Services
(Springer Singapore, 2021) Arnab Banerjee; Manoj Kumar Jhariya; Shailesh Kumar Yadav; Nahid Khan; Abhishek Raj; Ram Swaroop Meena; Taher Mechergui
The mega event of climatic perturbations has its severe impact on human health and also on the well-being of the global ecosystem. The major issue of changingclimate has affected various ecosystems globally in terms of acidification of oceans followed by elevated level of carbon dioxide. It has its severe impacts in various forms of habitat degeneration leading to huge loss of biodiversity. Therefore, there is an urgent need to inventory the climatic risks and its vulnerability issues and their subsequent management for developing ecosystem resiliencytoward climate change. Mitigating the changes in the climate solution based upon natural systems needs to be scientifically explored. The present chapter is an attempt to understand the climatic risks and vulnerabilities of ecosystem along with suitable strategies for the effective management of ecosystem change. The chapter concludes by finding the challenging opportunities and research initiatives toward the issue of nexus between climatic changes and ecosystem vulnerability and risks. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2021.
