“…Adaptation options are diverse in delta environments: these regions are accessible, productive and are frequently sites of major populations and urban economic growth poles 60 How delta resources are used are the outcome of myriads of individual decisions: hence a need for observational studies on agency and choice. Rice farming practices in deltas, for example, are highly exposed to both periodic floods and to creeping salinization, affecting food security and health outcomes 51,52 . In depth methods including semi-structured interviews and focus groups with farming communities in the Mahanadi delta in India, show that insecure land tenure and uneven access to credit drives the spatial patterns of vulnerability to environmental hazards 51 .…”

Studies of climate change at specific intervals of future warming have primarily been addressed through top-down approaches using climate projections and modelled impacts. In contrast, bottom-up approaches focus on the recent past and present vulnerability. Here, we examine climate signals at different increments of warming and consider the need to reconcile top-down and bottom-up approaches. We synthesise insights from recent studies in three climate-sensitive systems where change is a defining feature of the human-environment system. Whilst top-down and bottom-up approaches generate complementary insights into who and what is at risk, integrating their results is a much needed step towards developing relevant information to address the needs of immediate adaptation decisions.

“…However, resource constraints and the diverse needs of smallholders limit the flow of top-down information [24]. For example, resource constraints of agricultural extension staff have been identified as a challenge under climate change in the South Pacific [25] and the lack of transparency and connectivity a constraint to information delivery in India [26].…”

Multiple factors constrain smallholder agriculture and farmers’ adaptive capacities under changing climates, including access to information to support context appropriate farm decision-making. Current approaches to geographic information dissemination to smallholders, such as the rural extension model, are limited, yet advancements in internet and communication technologies (ICTs) could help augment these processes through the provision of agricultural geographic information (AGI) directly to farmers. We analysed recent ICT initiatives for communicating climate and agriculture-related information to smallholders for improved livelihoods and climate change adaptation. Through the critical analysis of initiatives, we identified opportunities for the success of future AGI developments. We systematically examined 27 AGI initiatives reported in academic and grey literature (e.g., organisational databases). Important factors identified for the success of initiatives include affordability, language(s), community partnerships, user collaboration, high quality and locally-relevant information through low-tech platforms, organisational trust, clear business models, and adaptability. We propose initiatives should be better-targeted to deliver AGI to regions in most need of climate adaptation assistance, including SE Asia, the Pacific, and the Caribbean. Further assessment of the most effective technological approaches is needed. Initiatives should be independently assessed for evaluation of their uptake and success, and local communities should be better-incorporated into the development of AGI initiatives.

“…Autonomous adaptation (at household or community levels) to SLR and other environmental change, e.g. sale of assets, switching livelihoods or accessing financial support will continue, provided the environment changes slowly (Duncan et al 2017). Appropriate adaptation buys time, but will not ultimately solve the problem of multimillennium climate-induced SLR without further mitigation.…”

“…Appropriate adaptation buys time, but will not ultimately solve the problem of multimillennium climate-induced SLR without further mitigation. Planned adaptations in deltas, guided by the government and other national or international organisations, are already documented, such as flood risk management plans and disaster risk reducing infrastructure (Tompkins et al 2017). Planned adaptation at the national level could support autonomous action at a local level at a larger geographical scale.…”

Even if climate change mitigation is successful, sea levels will keep rising. With subsidence, relative sea-level rise represents a long-term threat to low-lying deltas. A large part of coastal Bangladesh was analysed using the Delta Dynamic Integrated Emulator Model to determine changes in flood depth, area and population affected given sea-level rise equivalent to global mean temperature rises of 1.5, 2.0 and 3.0°C with respect to pre-industrial for three ensemble members of a modified A1B scenario. Annual climate variability today (with approximately 1.0°C of warming) is potentially more important, in terms of coastal impacts, than an additional 0.5°C warming. In coastal Bangladesh, the average depth of flooding in protected areas is projected to double to between 0.07 and 0.09 m when temperatures are projected at 3.0°C compared with 1.5°C. In unprotected areas, the depth of flooding is projected to increase by approximately 50% to 0.21-0.27 m, whilst the average area inundated increases 2.5 times (from 5 to 13% of the region) in the same temperature frame. The greatest area of land flooded is projected in the central and northeast regions. In contrast, lower flood depths, less land area flooded and fewer people are projected in the poldered west of the region. Over multi-centennial timescales, climate change mitigation and controlled sedimentation to maintain relative delta height are key to a delta's survival. With slow rates of sea-level rise, adaptation remains possible, but
