Introduction

More than a third is covered by drylands in the terrestrial land surface, which have a harsh and vulnerable natural condition (Maier et al., 2014). Due to insufficient water availability, dry areas have a scant population of vascular plants, as well as poor availability of the nutrient turnover with poor availability of the resources as a result of severe temperatures (Adeel, 2008). Biological soil crusts or Biocrusts commonly protects the soil surface in dry environments and it is considered “ecosystem engineers” of arid and semiarid areas, as well as signs of ecosystem health (Briggs and Morgan, 2011; Bowker et al., 2008). They are connected in dryland ecosystem restoration level or degradation (Assouline et al., 2015). When compared to chemical or physical crusts, biocrust is the largest word that explicitly implies that these are the crusts which are dependent on the living organisms’ activity.

Introduction

According to the Forest Survey of India (FSI) “all lands, more than one hectare in area, with a tree canopy density of more than 10% is defined as Forest” (FSI 2009). The status of forests and forest management systems contribute to the vulnerability of forests to climate change. Indian forests are extremely diverse and heterogeneous. Forests and Climate Change are intimately intertwined. Forests have regulated the climate, rain, groundwater, soil of the earth over millennia. Their transpiration act as a regulator of the balance of oxygen and carbon-di-oxide: the world’s forests and forest soils currently store more than one trillion tons of carbon – twice the amount found floating free in the atmosphere. The forest and soils are home of biological diversity.

Introduction

Future agricultural production potential is in danger due to the existing cropping system, characterized by irresponsible chemical utilization, extensive tillage, monoculture, and soil health degradation. Consequently, a significant challenge for modern agriculture lies in ensuring adequate nourishment for the entire world’s population while also safeguarding the environment. The intensification of agricultural practices negatively impacts vital natural resources like soil, water, air, and biodiversity throughout various developmental stages. While the conventional cropping system have enhanced crop productivity, its consequences including land degradation, resource depletion, reduced organic matter insoil, draught, soil salinity, erosion, and climate change pose significant global threats (Tomar et al. 2014; Yadav et al. 2014; Mandal et al. 2020; Rani et al. 2021).

Introduction

Soil is a vital, complex, and firm layer of the land surface that provides a source of minerals and organic matter interacting with air and water to harbor life forms. (Lobmann et al., 2022). Versatile micro and macro living organisms, i.e., bacteria, fungi, and actinomycetes, inhabit soil and contribute to its quality, health, and inevitable role in serving the environment (Elsakhawy et al., 2022). Soil roots for a variety of crucial functions which involve ecosystem services or socioeconomic activities, e.g., biomass production, climate gas fluxes of CO2 , N2 O, and CH4 , water cleaning, storage and supply, foundation of construction and provision of construction materials, or provision of habitats etc. The responsibility of soil in sustaining life on earth by providing and conserving resources is not negotiable.

Introduction

By enhancing microbial populations, enzyme activity, soil respiration, and microbial biomass, nano-black carbon is a novel method for the enhancement of soil biological characteristics. By reducing soil acidity and boosting soil fertility, nano-black carbon is believed to improve plant development. The application of nano-black carbon to agricultural soils can have a significant positive impact on plant productivity. In addition to potentially boosting soil resilience to climate change, nano-black carbon greatly boosted enzyme activity, microbial activity, and soil organic carbon retention.Due to a liming action, nano-black carbon has been proposed as a potential biotechnology to boost agricultural yields in acidic soils.

Introduction

Overview of the Chapter’s Focus on Agroecology and Soil Sustainability

The ecology and biodiversity of our globe are being threatened by human activity, notably unsustainable agriculture methods. This chapter explores the vital function of agroecology, the intersection of ecological and agricultural concepts, in promoting sustainable farming systems. Soil sustainability, essential for effective and resilient agrarian operations, is critical to this strategy. Here, we give an overview of these key terms and talk about the pressing need to switch to sustainable agriculture methods to preserve the  health of the soil, increase food security, and create adaptable environments.

Introduction

More than three billion people are at risk of poverty due to land degradation caused by humans (Kansanga, Kerr, Lupafya, Dakishoni, & Luginaah, 2021). The implementation of Soil Sustainability Management (SSM) practices remains low among smallholder farmers, despite the fact that SSM has developed as a generally accepted technique to tackling soil degradation in Agro ecosystems (Kansanga et al., 2021). When it comes to food, water, energy, climate, biodiversity, and the provision of ecosystem services, soil plays a pivotal role in addressing these global environmental sustainability concerns (McBratney, Field, & Koch, 2014). The availability of food, fiber, clean water, and a varied landscape are all dependent on healthy soil.

Introduction

Soil plays a vital role in fulfilling fundamental human requirements, such as the provision of sustenance and water, while also serving as the primary medium for supporting biodiversity. The sustainability of soil in the 21st century is dependent upon not only the implementation of effective management practices by farmers, foresters, and land-planners, but also on government regulations, policies, marketing strategies, and subsidies (Mishra et al., 2017). The increasing influence of human activities on the Earth’s natural environment has led to significant global challenges concerning the interplay of planetary and public health (J. Huang et al., 2018).

Introduction

Waste management and soil sustainability are two critical aspects of environmental conservation and sustainable development. As our global population continues to grow and consume resources at unprecedented rates, it becomes increasingly important to manage waste effectively and preserve our soil health and productivity. Anthropogenic activities have consistently produced waste. The World Bank predicts that worldwide garbage production will rise to 70% by 2050 if no substantial actions are taken (Ghosh, 2020). This was not a significant problem when the world’s population was small; however, it is acquired as a major concern with industrialization and urbanization revolution. Lack of proper waste management has caused pollution of water, land, and atmosphere, as well as a significant effect on human health (Raza et al., 2022a; Raza et al., 2022b).

Introduction to Soil Restoration and Management

One of the most crucial elements for human survival is the availability of arable land. Desertification caused by land degradation has emerged as a serious global environmental threat to human well-being and sustainable development in recent years because of both climatic shifts and an increase in human activities that have direct impacts on soil. It has been widely alarmed by the United Nations Convention to combat desertification and has shown considerable interest in this issue (UNCCD, 2015). Soil degradation is used to describe the transformation of arable land into unproductive land because of natural processes, typically accelerated by human activity (Lal, 1993).

Introduction

Organic farming is a comprehensive approach to production management that promotes and improves Agro-health, ecosystems including biodiversity, biological cycles, and soil biological activity. It prioritizes management approaches above off-farm inputs, and agronomic, biological, and mechanical farming procedures are used rather than synthetic resources (Ajibade, Ayinde, and Abdoulaye 2020). The term “organic farming” refers to a production technique that excludes the use of artificially formulated fertilizers, pesticides, or growth regulators for agronomic practices or the use of different chemicals for livestock production, i.e., feed additives, growth promoters and antibiotics, etc. (M. Singh 2021).

Introduction

Global population growth has led to an increase in demand for energy, food, and other essentials, resulting in an increase in agricultural land. Poor farming techniques, urbanization, and a lack of soil management measures have negative consequences for agricultural soils, such as reduced soil fertility, migration of soil organisms, and loss of soil microbiota and ultimately loss of soil health(Mehmood et al., 2020; Omotayo and Babalola, 2021; Syed et al., 2022). In addition, fertilizers used in agriculture have an impact on soil quality and health. Soil fertility is defined as the ability of a soil to meet the physico-chemical and biological requirements of a plant for growth, reproduction and quality, taking into account plant and soil type, land use and climatic conditions (Abbott and Murphy, 2007; Tyagi et al., 2019).

Introduction

Agriculture contributes a vital part within the financial stability of smallest emerging nations such as Pakistan as well. The economic system of Pakistan is fundamentally based upon agriculture (Govt. of Pakistan, 2004-2005). The total surface of Pakistan approximately 796,095 km2, of which 8.3 million km2 are uncultivated and 22 million km2 are farmed (Govt. of Pakistan 2015 2016). Despite an average yearly increase of 2.7%, agriculture contributes 21% of Pakistan’s GDP (Govt of Pakistan, 2004–2005). Farming is a sector whose fundamental and commercial models combine. Agriculture’s importance to the economy may be examined through three distinct perspectives: 1) as a source of nutritious food for the country and raw materials for internal industry; 2) as a way to generate currency from abroad and 3) as a source of products and services for local industries and the global market (Govt. of Pakistan, 2015-16).

Introduction

Soil is a non-renewable resource that sustains life, providing ecosystem services such as biomass production, contaminants filtration, raw material supply, nutrient, and hydrological cycle (Panagos et al., 2020). It contributes about 95% to global food production (Borrelli et al., 2020). Soil is a major global biodiversity pool and a large carbon pool on Earth. Therefore, it plays a crucial role in regulating energy and mass flow and their transfer between the biosphere, lithosphere, hydrosphere, and atmosphere (Ferreira et al., 2021). Climate change and unsustainable management practices are threatening the soil’s natural capital resulting in soil degradation occurring simply from erosion to contamination and leading the soil to completely unproductiveness under severe conditions, leading to food insecurity (Ashoka et al., 2017; Syed et al., 2022)

8.1 Recommendations

The specific recommendation for NAZ in promoting CA are

• Since fragmentation has come out as a barrier to CA, the community based CA entrepreneurship will be more successful to make CA ecologically resilient, economically viable and socially adoptable.
• Crop residues are viable source for soil nutrients including organic carbon replenishment, but unfortunately left over crop residues are either burnt out or wrongly used. So, a community bank on crop residues in the form of bio-parks on a commercial basis can be a dependable source of organic manure for being blended into the farm soil. Auditing on volume of disposable CR and its proper application can help in making operating farm more resilient and productive.
• Since CA farmers have to go through a minimum gestation period and they are expected to contribute to the ecological resilience and carbon sequestration, economic incentives must be extended for their productive as well as stewardship function. A policy promulgation is the need of the hour to support their contribution
• Since fragmentation of holding poses a potential threat to resource energy biodiversity and economic conservation, so a strong land and farm policy needs to be there to abate disintegration and fragmentation of holding

Since the Green Revolution of 1960s, Indian agriculture have been highly dependent on chemical fertilizers, exploitation of ground water for irrigation, intensive tillage etc. to raise the food grain production of the country towards ensuring food security for all. The consequences of these practices resulted in declined and degraded soil health, soil erosion and dried up water capillaries - ultimately posing threat to the sustainability of the future production. This invites the need of affordable changes in the agricultural practices without hampering the production. Conservation Agriculture, as put forward by FAO, is a set of sustainable agricultural practices, aims to conserve, improve and make efficient use of natural resources through management of soil, water and biological resources in aid with external inputs. The three basic principles of Conservation Agriculture include - minimum soil disturbances, permanent soil cover and crop rotation or crop diversification.

Table 1 Represents the distribution of variables in terms of range i.e. maximum and minimum values, mean, standard deviation and coefficient of variation for alluvial zone of West Bengal.

It has been found that for the independent variable age (x₁), the range lies between 82 and 27 years, where the oldest respondent is of 82 years and the youngest respondent being 27years old. The mean value of the age of the respondents in this study was found to be 51.49 years with a standard deviation of 12.42 in the dataset. Coefficient of variation for this variable was found to be 24.14 per cent, which indicates a high level of consistency in the distribution.

Research methodology is a detailed plan of investigation and the blue print of procedure for carrying out the research. In this chapter, discussion on the methodology has been made to understand the concepts, methods and techniques, which are utilized to design the study, collect information, analyzing data and interpreting the findings for revelation of truth and formulation of theories. The entire chapter has been broken up under following sub-heads for easy understanding:

1. Locale of research
2. Sampling design
3. Pilot study
4. Variables and their measurements

4.1 Research Setting

In any social science research, it is hardly possible to conceptualize and perceive the data and interpret the data more accurately until and unless a clear understanding of the characteristics in the area and attitude or the behavior of people is at commend of the interpreter who intends to unveil an understanding of the implication and behavioral complexes of the individual who live in the area under reference and form a representative part of the larger community. The socio-demographic background of the local people in a rural setting has been critically administered in this section. A research setting is a surrounding in which input and elements of research are contextually imbibed, interactive and mutually contributive to the system performance. Research setting is immensely important in the sense because it is characterizing and influencing the interplays of different factors and components.

The last century has witnessed a global change in agricultural practices. From high dependency on external input agriculture, the world is now shifting towards low external input sustainable agriculture (LEISA). The history of dustbowl devastation in 1930s in America has put agricultural practices, tillage in particular, to question (Friedrich et al., 2012). Traditionally, tillage was believed to be a primary farm operation for preparing a good seedbed, nutrient mobilization, weed management, moisture availability, crop residue incorporation (Hobbs et al., 2008), thereby improving the overall soil health with increased production (Farooq et al., 2011a). The dust bowl devastation of 1930s gave rise to the concept of protecting soil by reducing tillage operation and maintaining ground cover, popularized as conservation tillage (Friedrich et al., 2012). Economic and ecological sufferings caused by the disastrous droughts in USA during 1930s drove the shift towards conservation agriculture (CA) (Haggblade and Tembo, 2003).
