Agroecological Footprints Management for Sustainable Food System
(Springer Singapore, 2020) Arnab Banerjee; Ram Swaroop Meena; Manoj Kumar Jhariya; Dhiraj Kumar Yadav
Agroecological footprints are a unique and popular concept for sustainable food system. Measuring and keeping a tab on the agroecological footprints of various human activities has gained remarkable interest in the past decade. From a range of human activities, food production and agriculture are most essential as well as extremely dependent on the agroecosystems. It is therefore crucial to understand the interaction of agroecosystem constituents with the extensive agricultural practices. The environmental impact measured in terms of agroecological footprints for a healthy for the sustainable food system. The editors critically examine the status of agroecological footprints and how it can be maintained within sustainable limits. Drawing upon research and examples from around the world, the book is offering an up-to-date account, and insight into how agroecology can be implemented as a solution in the form of eco-friendly practices that would boost up the production, curbs the environmental impacts, improves the bio-capacity, and reduces the agroecological footprints. It further discusses the changing status of the agroecological footprints and the growth of other footprint tools and types, such as land, water, carbon, nitrogen, etc. This book will be of interest to teachers, researchers, government planners, climate change scientists, capacity builders, and policymakers. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, agroforestry, agroecology, soil science, and environmental sciences. National and international agricultural scientists, policymakers will also find this to be useful to achieve the ‘Sustainable Development Goals’. © Springer Nature Singapore Pte Ltd. 2021.
Ecological Footprints in Agroecosystem: An Overview
(Springer Singapore, 2020) Arnab Banerjee; Manoj Kumar Jhariya; Ram Swaroop Meena; Dhiraj Kumar Yadav
Agroecology has many pyramids on the earth, and has interaction between the living components. It encompasses the key issues such as food system on the planet and ecological concepts for greener future. Ecological footprint is a holistic approach which assesses the issue of sustainability both at macro-scale and micro-scale. In the present era, it has been observed that reduction in agricultural inputs helps to reduce the ecological footprints and support to the sustainable food system. However, this is absent due to intensive agricultural practices and huge use of agrochemical to feed the booming population of human being. The values of ecological footprints vary site wise. According to global footprint network food production contributes ~30% of the ecological footprint of the human civilization. On the basis of hectares per individual the value is 3 ha per individual globally for the food system. It is very interesting to note that the value of the developed nation stands to be higher in comparison to the poor economy or developing economy based on the status of countries. For example, the ecological footprints value of North America, Oceania and Europe ranges between 5 and 7 global hectares per individual and, on the other hand, the value of Africa, Asia, Latin American countries ranges between 0 and 3 global hectares per individual. In the Indian context, it is again much lesser of about 0.77 ha on individual basis. It has been observed that with intensive agriculture practices for more production agroecosystem stability reduces. Technological intervention is required for greener production, move towards low carbon economy, improving the biocapacity of the land which would help to reduce ecological footprint of the ecosystem. Hence, proper accounting of the natural resource is required for overall sustainability of the agroecosystem. Therefore, this book will support the government planners, policymakers, researchers, academicians and students to develop a vision to sustainable food, environmental and an economic system to fulfil the “Sustainable Development Goals”. © Springer Nature Singapore Pte Ltd. 2021.
Energy and Climate Footprint Towards the Environmental Sustainability
(Springer Singapore, 2020) Arnab Banerjee; Manoj Kumar Jhariya; Abhishek Raj; Dhiraj Kumar Yadav; Nahid Khan; Ram Swaroop Meena
Agriculture has a share of 5% energy use globally. Most of the source is not from the renewable sources leading huge amount of GHG (greenhouse gases) emission. As per the Paris agreement on the use of climate change the major emphasis should be given for reducing GHG emission. Therefore, the process of agriculture needs a modification. It was observed that the various forms of ecological footprint are very important for environmental sustainability of agroecosystem. Energy footprint estimation is a key issue in the era of energy crisis. Improved technology and processes has improved the lifestyle of common man and as a consequence of that the energy consumption has given at tremendous rise. The non-renewable energy sources are declining at a fast rate and therefore, emphasizing switching over to renewable alternatives. Moreover, the energy demand and footprint is increasing day by day. In the agroecosystem with improved agrotechnology and mechanization of the agriculture practices the energy requirement is gradually increasing day by day. It is leading to release of huge amount of GHG emission from the agroecosystem leading to increase in energy subsidy in agriculture sector. Energy footprint estimation in cropping system is therefore most needed aspect at the present time. Further emission of huge amount of GHG from the agroecosystem is creating the problem of climate change and global warming. Therefore, the climate footprint of the earth ecosystem is also reflecting changing pattern. It is also hampering the agricultural productivity and production. Proper management of agriculture through organic farming, crop rotation and other indigenous technologies under changing climate has become the biggest challenge on the earth surface. The concept of energy footprint is associated with the level of GHG emission that is taking place from various sectors of agroecosystem. Addressing environmental sustainability in the field of agriculture requires sustainable and integrated management of resources along with emission reduction of GHGs. This would help to reduce the energy footprint of the agroecosystem and subsequently help in combating climate change. The pattern of climate footprint needs to be conserved in order to avoid the hazards of the changing climate that is challenging the issue of environmental sustainability. Therefore, analysing climate and energy footprint is a key issue from agroecosystem point of view in order to attain environmental sustainability of the agriculture sector. © Springer Nature Singapore Pte Ltd. 2021.
