Drought and Heat Stress in Agriculture: Implications, Mitigation and Policy Approaches
(Springer Science+Business Media, 2025) Rachana Dubey; Kumari Shubha; Sanjeev Raj Kumar; Amitava Rakshit; Anup Das
This edited book provides critical insights into changing climate's impact on agriculture and innovative strategies for building resilience. The agricultural sector is highly dependent on climatic conditions, is particularly vulnerable to the impacts of drought and heat stress. It has been notices that crop yields in Africa, Asia, and the Middle East are reduced by 15–35% when temperatures rise by 3-4 °C. The book explores the impacts of climate change on agriculture and how farmers can adapt their practices to overcome the dual threat of drought and heat stress on cereals, pulses, oilseeds, vegetables, and other allied sectors. One of the key themes of the book is the importance of smart water management in building agricultural resilience to drought and heat stress. By adeptly managing water resources and nurturing soil health through practices like cover cropping and reduced tillage, farmers bolster their resilience. Additionally, livestock management strategies are explored to combat reduced productivity and health issues due to heat stress. Harnessing the power of AI-assisted solutions, the book showcases how cutting-edge technology aids data-driven decisions on crop management and irrigation. This book is a vital resource for farmers, researchers, policymakers, and those concerned about our food systems' future. It emphasizes the urgent need for climate-smart agricultural policies and technologies, offering prospects for sustainable practices and resilient food production. © 2025 The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

On earth, soil is one of the most essential parts of nature which plays critical roles in plant growth, water flow, waste products recycling and provides habitats to various organisms. Soil is the combination of organic matter, air, water minerals, and sixteen different essential nutrient elements which are categorized into primary macronutrients, secondary macronutrients, and micronutrients. The nutrients elements present in soil either in organic forms or organic forms interchanged by the various microbial mechanisms such including fixation, chelation and solubilization. The microbes from all three domain i.e., archaea, bacteria, and eukarya have been reported for exhibiting the various mechanisms and strain belonging to genera Arthrobacter, Burkholderia, Bacillus, Paenibacillus, Pseudomonas, Rhizobium, Natrinema, and Serratia are widely known for ruling the nutrients dynamics. The microbes playing role in nutrients dynamics, have great economic importance in agriculture sector as agriculturist is in pressure of producing high quality and quantity of food along with managing the sustainability. These microbes could solve agricultural problems such as soil degradation and environmental pollution by using them as bio-fertilizer over chemical-based products. A huge number of reports have supported such statements so, the purpose of the present review aims to complies microbial role in all category nutrients dynamics and their role in plant growth promotion. © Association of Microbiologists of India 2024.
