The magnitude and trajectory of changes in ecosystem services and functioning have been as conspicuous as has never been until before 1980’s in this subcontinent. Both the services and resilience of agro-ecosystem, the pivotal for agricultural production and security have been disrupted in the name of modernization of agriculture as well as commercialization. The impact of green revolution in India, that look place during 1960’s and 1970’s have started eroding very fast and as the consequence of this green revolution, the ground water depletion has gone to the worst, it is contaminated either. 40 % of ground water in Punjab has been moderately or severely contaminated leaving agriculture a coercive proposition both from economic and ecological perspective. 10-15 tonnes of top soil are being eroded per hectare per year in its wrong welcoming to farm mechanization process. Most of the highly yielding varieties which did the ‘magic revolution’ now has been fatigued or segregated either. The social-ecological impacts on agriculture perhaps have been both disruptive and deleterious. Due to unabated fragmentation of holding which again is tiny in size, has initiated another problem of resource and energy wastage, bad enough to add to an ecological disruptions. With a non-denial to the gleaming success of green revolution, which ensured us with much awaited food security and self-reliance, has its intrinsic weakness and coercion as well.

This chapter reviews the research work done in the fields related to the objectives of the study. In any scientific investigation or research a comprehensive review of relevant literature is very essential. Its main function apart from determining the work done before concerning the problem area i.e. area of investigation, it provides an insight into the methods and procedures and create a basis for interpretation of findings. As direct references on all the item are not in abundance, certain specific references along with some indirect references have been incorporated this chapter for the purpose of meaningful use. 2.1. Ecosystem Services and Conservation Agriculture Acharya, S. K. and Chatterjee, R. (2019) found that conservation agriculture may help in re-building agro-ecology by maintaining carbon sequestration, maintaining soil health, checking soil erosion and ground water depletion, energy balance, mitigating climate change related problems through maintaining ecosystem services. Ayyam, V., Palanivel, S., and Chandrakasan, S. (2019) stated that CA embraces higher rates of carbon sequestration, organic matter accumulation, soil erosion reduction, and its associated improvement in soil biological properties. Additionally, there is reduction in greenhouse gas emission as a result of CA. Adoption of CA-based farming practices particularly in areas facing notable land degradation and depleting natural resources delineates a win-win scenario due to improved crop yield and trends of increasing soil fertility and scope for climate change adaptation to recuperate degraded soils and improve ecosystem services.

3. Contemporary Crisis in Global Agriculture Over the past century, bunch of initiatives have been taken and achieved worldwide in expediting human welfare. Societies have also changed to great extent as a result of quantum leaps in technology, rapid globalization, and innovations in agricultural production systems. Perhaps the world ‘free of fear and want’ envisioned at the foundation programme of the United Nations is still a far cry. Similarly, much work left to be fulfilled the vision of the Food and Agriculture Organization of the United Nations (FAO) and to make ‘a world free of hunger and malnutrition and one in which food and agriculture contribute to improving the living standards of all, especially the poorest, in an economically, socially, and environmentally sustainable manner’. Amidst great plenty, millions of people still face pervasive poverty, inequalities, joblessness, natural resource depletion, environmental degradation, displacement, migration, disease, and deprivation. Majority of humanity’s progress has reached at a significant cost to the environment. The impacts of climate change are already being felt, and if left unabated; definitely will intensify to a considerable extent in the years coming. Besides, population dynamics will radically change demographics over the decades ahead. Growth in the world’s population is projected to be concentrated in Africa and South Asia and in the biggest cities. Then agricultural production has to maintain pace with those of rising population for atleast a sustainable world. Although, agricultural production more than tripled between the years of 1960 and 2015, where Green Revolution owes to robust crop production and a significant increment in the use of land, water and other natural resources for agricultural purposes. This period witnessed a remarkable progress in both of industrialization and globalization of food and agriculture. At the same time changes in the length of food supply chains took place as the physical distance from farm to plate has increased dramatically; the consumption pattern of processed, packaged, and prepared foods has changed simultaneously in everywhere though the most in rural communities.

4. Research Setting Research setting presents the set of an ecosystem, here social-ecological systems, where the variables and characters are created, evolved, characterized and interact with others. Research setting is not a stale or lentic ecosystem rather it is agile, evolving and dynamic, so in this present work, we have perceived research setting as the performing social-ecology which sustains and keeps constantly characterizing the behaviour and dynamics of the variables under study, e.g. a settlement in close proximity to natural water body is expected to have interaction with ethiophonal diversity and performing economy therewith similarly, another set of respondents with the same set of variables but living in a forest ecosystem. The interaction and exposition of the variables will follow a different expression and pathway. So, while we will go for modelling, with the same set of variables but in different ecological set up, it is expected that the nature of interaction and expression will follow the unique characters of the concerned ecosystem. 4.1. Area of Study The area of investigation of this study is situated in the state of West Bengal located in the eastern part of India. The state of West Bengal in eastern India has unique social and ecological backgrounds which influence the living standard and behavioural patterns of the people in many ways. The present research design has accommodated two agro- ecological set ups in West Bengal, India, and these are New Alluvial and Terai zone.

The deliberation on the methodology has been made to understand the concept, methods, and techniques which were utilized to design the study, collection of information, analysis of the data and interpretation of the findings for revelation of truths and formulation of theories. This chapter deals with the method and a procedure used in the study and consists of eight main parts- • Locale of research • Pilot study • Sampling Design and Framework • Empirical measurement of the variables • Item analysis and experts rating for devising scoring technique on dependent variables • Preparation of interview Schedule • Pre testing of Interview Schedule • Techniques of Data collection • Statistical Tools used for Analysis of Data 5.1.

First Part: Multivariate Statistical Analysis 6.1. Results The chapter deals with the result and discussion of the study using multivariate statistical analysis and participatory Rural Appraisal (PRA) techniques with the purpose to provide sufficient information so as to arrive at valid conclusion. Tables and models are commonly used in this chapter to support and supplement the textual materials. Discussion helps to interpret the results of the study in proper perspective and to relate them with other relevant studies. Axiomatic statement on the variable interactions and behaviour selected for the study Research setting in the present study presents a dynamic social-ecology which is evolving along and across the undulation of social process. Both the structural and functional dimensions and behaviour are in constant interaction and response with the subject respondents in terms of innumerable variables. For the present research only some selected characters have been selected for empirical titration. There is no wonder these variables can be catalogued in terms of dependent or independent variables rather should not be distributed in a binary mode. Rather these variables are with seamless transformations like the algorithm of quantum physics. That is how whenever a set of x variables are supposed to behave with a contributor characters the same can be responsive with a recipient behaviour, e.g. in stepwise regression, set of ‘x variables’ are not considered as the only source of causal variables along with the couple of ‘y variables’ which are promoting rest other y variables have also been considered as causal variables. Hence, in case of y1, the rest of the y variables have to be treated like: y2 = y2' ; y3' = y3; y4 = y4' and so on.

7.1. Summary The planet rise at this moment cannot endure and conjure up any further stress and distress created by un-mindful modernization of agriculture. This situation has gone further complex with the unabated rate of urbanization. The natural resources which looked plenty some 50 years back, now is coming up something scant and degraded. We have to protect this planet; hence, we have to protect our agriculture by placing ecological resilience with its perfect balance and dynamics. In doing so, we need to manage and recycle energy, water, and biodiversity in such a way that the operating agro-ecosystem can perform for another centuries. This is a herculean task, it will only be possible when farmers and other citizens are participating elegantly and equally into the process, because farmers are not producing food for their own, rather they are feeding the entire civilization. Every year 15-20 tonnes of top soils are being eroded, the highest anytime; the sea level is rising at the rate 5-10 mm again it has become highest over the last decades and the prediction for rate of changes in rainfall and temperature contributing to global warming has been accelerate like anything. In addition to this, we need to feed 950 crores of population by 2050, while lands are getting fragmented, resources are fragile, and water is getting increasingly contaminated. Thus, CA is the only option to create a perfect balance between productivity with increase of ecological resilience, even within the cropping system by introducing crop diversification with leguminous crops and this is specially so when the biodiversity is also getting eroded. Water harvesting is the need of the hour as we can make our farm more energy parsimonious, we have direct whatever crop residues are produced in the soil echelon and making this concept a revolution into a reality we have to go in a massive way with bring awareness, creating policies, and mobilizing community to make our agriculture ever- green and ever- resilient. On this context the present research has been conducted with the following objectives:

Future Scope of the research 1. Inclusion of more number of relevant variables to generate and delineate complex interactions in the ecosystem functioning with a focus on agriculture, livestock, and forest. 2. The future research merits application of data analytics for visualization, prediction, and prescription of CA beyond time and geography 3. A robust Management Information System (MIS) needs to be the possibility of related to CA and allied natural resource management can help better and effective research interpretation and policy formulation as well, 4. Application of artificial intelligence can go immensely important in monitoring, auditing, and analyzing ecological services. Recommendations from the study/ Area of Intervention 1. Rationalization of chemical fertilizer and pesticides in a gradual manner and for which there will an environmental policy in place, 2. A data bank needs to be created on agricultural pollution and necessary recommendation from the environment and pollution department need to be made, 3. Fragmentation has come out as one of the barrier towards the socialization of Conservation Agriculture since small farms are energy and input prodigal, so we have to go for community based farming or farm enterprise creation in state of isolated and individual endeavours, 4. Through panchayat and rural development sector policies need to be promulgated, 5. Gender issues are coming up very strong and conspicuous in Conservation Agriculture, the more is the women participation in CA, the better has been the success, hence, gender mobilization can be a program and policy of the government in making CA sustainable,
