“…For instance, Dubey et al (2019) have assessed the potential of different soil amendments for improving the soil quality in different agro-ecological zones of India. Moreover, Abhilash et al (2012) and Tripathi et al (2019) have suggested the potential of plant-microbe interactions as a remedy for contaminated lands. Furthermore, Edrisi et al (2020) have assessed the sustainability potential of alien plant species and suggested their careful utilisation for restoring marginal and degraded lands in northern India.…”

Restoration of degraded land is imperative for addressing climate change, deriving additional benefits such as biomass and biofuel for supporting a biobased economy and also for meeting various targets of the Bonn Challenge and the UN Sustainable Development Goals (UN-SDGs). In this context, the present research aimed to evaluate the performance of mixed biomass plantations on the saline land of western India over a period of 4 years. The impact of plantations on soil quality over the study period (2015)(2016)(2017)(2018) was analysed by the Saline Soil Reclamation Index (SSRI), developed through principal component analysis. The study found a strong correlation between plant growth attributes and soil quality (p < .01). Soil porosity, texture, pH balance, electrical conductivity (EC), available potassium (AK) and available nitrogen (AN) levels are found to be the key indicators regulating the plant growth. The EC, AK and AN levels were seen to change significantly during the initial stage (2014) from 25 dS m −1 , 10 mg kg −1 and 23 mg kg −1 to 1 dS m −1 , 24 mg kg −1 and 39 mg kg −1 , respectively, towards the end of the study period (2018). Among the various test plants, six species (Albizia lebbeck, Casuarina equisetifolia, Cordia dichotoma, Pithecellobium dulce, Pongamia pinnata, Terminalia arjuna) were found with high SSRI (>0.50); while the rest displayed moderate SSRI (0.30-0.49), except for Azadirachta indica, which shown low SSRI (<0.30). The trees having high SSRI are most suitable for the reclamation of saline soil and therefore, SSRI can be used as a tool for assessing the progress of saline land restoration.

“…Land is a complex biophysical system providing vital ecosystem services for human wellbeing and a good quality of life [1][2][3][4]. It supports primary production for feeding a rapidly growing human population and livestock, maintaining biodiversity and resultant ecological complexities (i.e., from species to ecosystems, and landscapes to biomes) [5][6][7] and plays a central role in cycling of nutrients [8] (i.e., C, N, P), water [9], and other critical elements [3][4][5][6]; and regulating the emission of trace gases (i.e., CH4, CO2, N2O, NO) and the earth's climate [2][3][4][5][6][7][8][9][10][11]. Moreover, land is perceived as an important production factor (as an economic resource) for overall human development [10] (www.undp.org), and also has enormous social, biocultural, and religious significance [1][2][3]11].…”

“…Therefore, protecting land system is essential for protecting our own future. Unfortunately, more than 33% of the global land resources is already degraded due to various direct and indirect drivers of changes [1][2][3][4][15][16][17][18][19][20][21] including pollution due to rapid agriculturalization [5,6,10], urbanization, and industrialization; unsustainable land use practices [15], deforestation [18], salinization [17], desertification, natural and human induced fires, soil erosion, overexploitation of groundwater and other critical natural resources, mining activities, invasive alien plants, climate change, poor land governance and policy measures, behavioral changes, etc. [7,[15][16][17][18][19][20][21].…”

“…[31,32]; there are no well-defined indicators for assessing the extent and severity of degradation in non-forested areas like agroecosystems [6,33] and other land use. In the latter one, the ecological profiling of soil, including physical, chemical, and microbiological profiling is the only way to understand the level of degradation [5,24]. Hence, it will require a considerable amount of time, labor, and other resources for undertaking the soil quality profiling of non-forested areas at a global scale for ascertaining the extent of land quality degradation.…”

Restoring the health of degraded land is critical for overall human development as land is a vital life-supporting system, directly or indirectly influencing the attainment of the UN Sustainable Development Goals (UN-SDGs). However, more than 33% of the global land is degraded and thereby affecting the livelihood of billions of people worldwide. Realizing this fact, the 73rd session of the UN Assembly has formally adopted a resolution to celebrate 2021-2030 as the UN Decade on Ecosystem Restoration (UN-DER), for preventing, halting, and reversing degradation of ecosystems worldwide. While this move is historic and beneficial for both people and the planet, restoration of degraded land at different scales and levels requires a paradigm shift in existing restoration approaches, fueled by the application of applied science to citizen/community-based science, and tapping of indigenous and local knowledge to advanced technological breakthroughs. In addition, there is a need of strong political will and positive behavioral changes to strengthen restoration initiatives at the grassroot level and involvement of people from all walks of life (i.e., from politicians to peasants and social workers to scientists) are essential for achieving the targets of the UN-DER. Similarly, financing restoration on the ground by the collective contribution of individuals (crowd funding) and institutions (institutional funding) are critical for maintaining the momentum. Private companies can earmark lion-share of their corporate social responsibility fund (CSR fund) exclusively for restoration. The adoption of suitable bioeconomy models is crucial for maintaining the perpetuity of the restoration by exploring co-benefits, and also for ensuring stakeholder involvements during and after the restoration. This review underpins various challenges and plausible solutions to avoid, reduce, and reverse global land degradation as envisioned during the UN-DER, while fulfilling the objectives of other ongoing initiatives like the Bonn Challenge and the UN-SDGs.

Restoration practices in marginal lands for food production are the most important sustainability challenge for humans at the global level. Nature-based solutions (NBS) are among the best interventions to improve soil health, which directly enhances the soil productivity and biodiversity for improved sustainability of ecosystems. Our field experiment was conducted to evaluate the effects of three inoculants, two of which were bacterial: Azotobacter chroococcum (T1), Acetobacter diazotrophicus (T2), and the third fungal: Aspergillus awamori (T3) on soil properties, plant biomass, enzymatic activities (phosphatase, dehydrogenase activity), and soil carbon stock in marginal lands. The experimental results clearly revealed that the inoculations significantly enhanced plant growth and biomass (p < 0.01). The soil enzyme (dehydrogenase and phosphatase) activities increased under T3 and T2 treatments in response to inoculation. Interestingly, the significant results were observed in T3 and T1 treatment in the 4th year of observation for soil carbon stock (53.06 Mg ha À1 yr À1 and 51.41 Mg ha À1 yr À1 , respectively). The total soil carbon stock was found to be 38.60 Mg ha À1 yr À1 in control plots. The inoculation enhanced (p ≤ 0.05) the soil biological properties like microbial biomass carbon as 267.62 ± 18.73 μgg À1 to 894.24 ± 41.65 μg g À1 . We conclude that selected inoculations in marginal lands can provide a suitable option for eco-restoration and can sequester more atmospheric CO 2 in to stable carbon pools to achieve UN Sustainable Development Goals and food security.
