“…This study has particularly addressed this underreported issue and examined farm-level and extra-farm factors influencing future LULC changes on an island of the Indian Sundarbans. For example, a satellite-based approach may capture the cropping intensity dynamics [48] but may not precisely account for how microlevel factors shape the resource allocation for ZTPC. Furthermore, it is difficult to capture how factors in a complex socioecological system interact (captured in the cognitive map) to affect the future upscaling of ZTPC on Satjelia Island.…”

Upscaling sustainable intensification (SI) technologies is crucial to enhancing the resilience of fragile farming systems and vulnerable livelihoods of smallholder farmers. It is also critical to shape the future land-use and land-cover changes in a region. Zero-tillage potato cultivation (ZTPC), introduced as an SI intervention in parts of the Indian Sundarbans, has demonstrated promises of rapid upscaling, and thus, changes in the seasonal land-use pattern in the region. This study aims to understand the socioecological complexity of farming systems to comprehend how the nascent stage of ZTPC thrives at the farm level and what preconditions are necessary to upscale them. The objectives are to analyse the farm resource recycling pattern in ZTPC, and map and simulate its system’s complexity to strategize ZTPC upscaling in the region. The analysis of farm resource recycling data reveals that ZTPC stability hinges on managing trade-offs in resource allocations, specifically involving straw, organic manure, sweet water, and family labour. The decision to manage such trade-offs depends on farm type characterizations by their landholdings, distance from the homestead, pond, and cattle ownership, competing crops, and family composition. Using a semiquantitative systems model developed through fuzzy cognitive mapping, the study underscores the significance of effective training, input support, enterprise diversification by introducing livestock, timely tuber supply, access to critical irrigation, and capacity building of local institutions as the essential preconditions to sustain and upscale ZTPC. This research contributes a systems perspective to predict agricultural land use within technology transfer initiatives, providing insights into how farm- and extra-farm factors influence resource allocations for ZTPC. Public extension offices must understand the trade-offs associated with straw, organic matter, and harvested water and design differentiated supports for different farm types. The most compelling interventions to upscale ZTPC includes farm diversification by introducing livestock through institutional convergence, pragmatic agroforestry initiatives to enhance on-farm biomass and fuel production, building awareness and integrating alternative energy use to save straw and cow dung, building social capital to ensure access to sweet irrigation water, and developing and/or strengthening farmer collectives to ensure the supply of quality tuber and marketing of farm produce.

“…14 Scaling out of technologies needs a more detailed assessment of where to promote particular options to suit the constraints of each location. Mapping of cropping systems in West Bengal coastal zone indicate the degree of landscape diversity (Ghosh et al, 2019(Ghosh et al, , 2023a(Ghosh et al, , 2023bNanda et al, 2023). Demonstrations of technologies and Rabi season crops need to be completed more comprehensively across the Coastal zone.…”

“…With continuing climate change in the Ganges Delta (Ghosh et al, 2021;Karim et al, 2024), farming systems will approach critical tipping points: land will become increasing salinized, waterlogged, and prone to storm surges; heat stress and seasonal droughts will become more important as limiting factors. This will necessitate the evolution of farming systems.…”

“…The cropping intensification options will vary according to land type. Remote sensing technologies can be used to classify the landscape according to land use (Ghosh et al, 2019). Satellite Remote Sensing (RS) data from the petabyte Landsat reflectance archive available via Google Earth Engine (Gorelick et al, 2017), or Open Data Cube (https://www.opendatacube.org/) coupled with advances in geospatial techniques to filter clouds and fill gaps in the RS imagery (Cao et al, 2018;Zhou et al, 2015) plus the now ubiquitous techniques of data mining and pattern recognition via machine and deep learning used for landscape mapping (Li et al, 2019;Xu et al, 2020), provide an opportunity to look back to the 1980s and capture the dynamics of land cover changes month-by-month and at 30 m spatial resolution.…”
