Hardcover. Condizione: New. Uncertainty and Chaos in Indian Farming: Production,Livelihood and Income by S.K. Acharaya, A.B. Sharangi & Swagata Patra ISBN: 9788119002245 | Binding: Hardback | Pages: 131 | Language: English | Year of Publishing: 2023 Length: 152 mm | Breadth: 13 mm | Height: 229 mm Hardback INR 1,995.00 INR 1,796.00 1 Shipping: Free Worldwide Delivery Within 10-15 Days By Indian Post (Traceable Methods) Indian agriculture at large has been on trajectory of grand uncertainty. The brunt of climate change, sharp undulation in productivity, unpredictability in market price, the consistent up rise in cost of cultivation and downfall of net return are amounting to what we may call the grand uncertainty. Uncertainty is an inevitable character of any system where most of the contributory factors are either unpredictable or unfathomable. The higher is the complexity, the lesser would be the resilience, and higher would be the uncertainty. Agricultural production system, as it is managed in Indian condition, is the most vulnerable to a plethora of uncertainties. Mostly managed in an open air rain fed conditions, complex-diverse-risk prone, it has been exposed to weather and resource uncertainties, market volatility, poor access to technology and a fragile input delivery mechanism. Indian Agriculture is now at a crossroad and gets confronted by uncertainty and unpredictability. The growth rate of food production runs just marginally above population growth. The book has uniquely dealt with a basket of perceived uncertainties that makes farmers and economy reel under stress and risk. The world s largest agrarian economy is being managed mostly by private land owners, who are mostly under the clutch of middlemen and vagaries of weather. The book, based on an empirical study, has indentified the marker variables of farmers in responding to and complying with the unpredictability and freaks of social dynamics.

The origin of agroforestry practices, i.e. growing trees and shrubs with food and fruit crops and grasses is traditional and very old; but the science of agroforestry is new. Years of experience and experiments have shown that agroforestry as a land-use system is capable of yielding both food and wood and at the same time helps in conserving and rehabilitating the ecosystems. It has the capability to increase the overall productivity of land, maintain the nutrient balance in the soil and above all protect the nature. In the recent years, agroforestry has been recommended as a core subject in the curriculum of B. Sc. (Forestry) and B. Sc. (Agriculture) courses of the state agricultural universities. Keeping this in view, the book on has been written for the students. The common people, who love trees, would also find it worth reading. The book has been divided into sixteen chapters covering very comprehensive information on all aspects of agroforestry including history, concepts, classification, management, soil productivity, tree-crop interactions, multipurpose trees and their propagation, agroforestry for different agroclimatic zones, watershed and wasteland management through agroforestry, climate change adaptation and mitigation, diagnosis & design, experimental analysis, benefits and limitations, economics and extension of agroforestry. Definitions of agroforestry terminology, selected references and related web links are also added for the easy understanding and further study on the subject.

Global food security has been threatened by climate change and has become one of the most important challenges in the 21st century to supply sufficient food and nutrition for the increasing population while sustaining the already stressed environment. Studies on impacts of climate change and adaptation strategies to overcome such problems are increasingly becoming major areas of concerns for the scientists, researchers and policy makers. The climate change impacts on the production of crops like rice, wheat, maize, soybean and water resources in the river basin catchments have been studies by researchers in many parts of the world using simulation modelling. Crop productivity and soil water balance have been studied with crop growth models by using parameters from different climate models. Meanwhile, climate variability is one of the most significant factors influencing year to year crop production, even in high yield and high-technology agricultural areas. In recent years, more and more attention has been paid to the risks associated with climate change and associated problems and hence on productivity of crops in agriculture. Water availability will be one of the limiting constrains for crop production and food security. Therefore, it is an urgent need to determine the impacts of climate change on crop production in order to employ possible adaptation strategies in farm level as well as regional level. In the last decade, crop simulation models have become essential tools to support field research and agricultural productivity in developing and d.
