    (The Royal Society, 2022-10-24) Goodwin, Daniel; Holman, Ian P.; Sutcliffe, Chloe; Salmoral, Gloria; Pardthaisong, Liwa; Visessri, Supattra; Ekkawatpanit, Chaiwat; Rey Vicario, Dolores
    The intensification of drought affects agricultural production, leading to economic losses, environmental degradation and social impacts. To move toward more resilient system configurations requires understanding the processes that shape farmers' adaptation amidst complex institutional contexts. Social networks are an important part of collective action for supporting adaptive capacity and there are continuing calls to strengthen network connectivity for agricultural governance under the impacts of climate change. Through a survey of 176 farmers in northern Thailand, we explore the extent to which the characteristics of information shared in a catchment advice network are associated with adaptations. Statistical analyses reveal the perceived efficacy of communications as well as farmers’ relative closeness in the advice network to be positively associated with adaptation to drought. We identify a capacity for local actors to bridge information bottlenecks in the network and opportunities for institutions to enhance their dissemination of information to reach less networked farmers. We find that not all adaptations are perceived as effective against future drought and infer opportunities to support engagement with extension services, encourage the sharing of local knowledge and experience and devise policy and interventions to strengthen advice networks for more resilient agricultural systems.

    Indicator-to-impact links to help improve agricultural drought preparedness in Thailand
    (EGU: European Geophysical Union, 2023-07-06) Tanguy, Maliko; Eastman, Michael; Magee, Eugene; Barker, Lucy J.; Chitson, Thomas; Ekkawatpanit, Chaiwat; Goodwin, Daniel; Hannaford, Jamie; Holman, Ian P.; Pardthaisong, Liwa; Parry, Simon; Rey Vicario, Dolores; Visessri, Supattra
    Droughts in Thailand are becoming more severe due to climate change. Developing a reliable drought monitoring and early warning system (DMEWS) is essential to strengthen a country's resilience to droughts. However, for a DMEWS to be valuable, the drought indicators provided to stakeholders must have relevance to tangible impacts on the ground. Here, we analyse drought indicator-to-impact relationships in Thailand, using a combination of correlation analysis and machine learning techniques (random forest). In the correlation analysis, we study the link between meteorological drought indicators and high-resolution remote sensing vegetation indices used as proxies for crop yield and forest growth impacts. Our analysis shows that this link varies depending on land use, season and region. The random forest models built to estimate regional crop productivity allow a more in-depth analysis of the crop- and region-specific importance of different drought indicators. The results highlight seasonal patterns of drought vulnerability for individual crops, usually linked to their growing season, although the effects are somewhat attenuated in irrigated regions. Integration of the approaches provides new, detailed knowledge of crop- and region-specific indicator-to-impact links, which can form the basis of targeted mitigation actions in an improved DMEWS in Thailand and could be applied to other parts of Southeast Asia and beyond.

    Stakeholder perceptions of drought resilience using government drought compensation in Thailand
    (Elsevier, 2025-04-15) Chengot, Rishma; Goodwin, Daniel; Tanguy, Maliko; Armitage, Rachael; Pardthaisong, Liwa; Jha, Srinidhi; Holman, Ian; Rey Vicario, Dolores; Visessri, Supattra; Ekkawatpanit, Chaiwat; Hannaford, Jamie
    In the context of escalating climate challenges in Southeast Asia, this study investigates the dynamics of disaster budget allocation in Thailand and examines farmers' perceptions of drought compensation, focusing on the Ping catchment situated in the Northwest of the country. The main objective of the study was to gauge stakeholders' awareness and views on government drought compensation and evaluate its effectiveness. Using government budget data, drought indicators, and a comprehensive survey in Chiang Mai and Tak provinces, the study explores correlations between budget allocation, drought indicators, and farmers' experiences. A correlation analysis unveils stronger links between compensation and Vegetation Condition Index (VCI) as compared to Drought Severity Index (DSI), with regional variations and the impact of irrigation practices. Compensation shows positive correlations with drought severity, suggesting support to farmers occurs when they suffer severe crop damage. We investigate drought occurrences and their impacts along with farmer's awareness and experiences of drought compensation schemes to uncover disparities in awareness, application rates, and satisfaction levels, providing insights into farmers' views on compensation effectiveness. The study concludes by proposing policy adjustments, tailored regional approaches, and feedback mechanisms to enhance the effectiveness of drought compensation strategies. Despite limitations in sample size and potential biases, this study contributes valuable insights into the complex dynamics of disaster budget allocation, drought compensation, and farmers' perspectives in Thailand, laying a foundation for refining policies and fostering sustainable agricultural practices amidst increasing climate challenges.

    What is the evidence linking financial assistance for drought-affected agriculture and resilience in tropical Asia? a systematic review
    (Springer, 2022-01-17) Goodwin, Daniel; Holman, Ian P.; Pardthaisong, Liwa; Visessri, Supattra; Ekkawatpanit, Chaiwat; Rey Vicario, Dolores
    Agriculture is sensitive to drought and associated social, environmental and economic impacts. Finance-based interventions aim to support farmers affected by drought; however, the extent to which such tools encourage resilience to this natural hazard is unclear. This paper systematically reviews evidence on links between financial interventions to mitigate drought-related impacts and adaptation towards longer-term resilience. We focus on tropical Asia where agriculture contributes significantly to national economies and is a primary source of livelihood in a region subject to high climate variability and episodic drought. Guided by Population, Intervention, Comparator and Outcome criteria, we identify and review 43 regionally specific articles that describe a range of financial interventions. Through thematic synthesis, we document the interventions’ associations with micro-level and macro-level outcomes. The results reveal how some interventions helped sustain household incomes and crop yield (e.g. through farm investments that increased productivity) through drought, whilst others encouraged adaptive behaviours. At a macro-level, there were challenges associated with government budgets and scheme administration, with the longevity of many schemes difficult to sustain. From fragmented evidence, this review reasons that there can be challenging policy trade-offs for institutions between supporting livelihoods and economic growth whilst also protecting the environment—highlighting the interdependence of systems’ resilience and variability in actors’ capacity to adapt. Low-regret interventions that integrate existing community adaptive practices, engage with farmers’ needs and prioritise extension support may encourage more desirable counteractions to drought; however, further research is needed to establish the role of such interventions.

    Which factors determine adaptation to drought amongst farmers in Northern Thailand? Investigating farmers’ appraisals of risk and adaptation and their exposure to drought information communications as determinants of their adaptive responses
    (Springer, 2024-01-11) Sutcliffe, Chloe; Holman, Ian P.; Goodwin, Daniel; Salmoral, Gloria; Pardthaisong, Liwa; Visessri, Supattra; Ekkawatpanit, Chaiwat; Rey, Dolores
    Drought communications constitute an important source of learning about climate risks and responses that can assist adaptation decision-making amongst those whose livelihoods are threatened by drought. This paper applies Protection Motivation Theory to explore associations between drought communications and attitudes towards drought risk and adaptation amongst farmers in Northern Thailand. The analysis reveals links between drought communications, farmers’ adaptation appraisal, and their adaptation decisions, whilst links with risk appraisal are minimal. The results highlight positive feedbacks between adaptation experience and appraisal and reveal a weak negative relationship between risk appraisal and adaptation appraisal. The findings imply benefits to framing drought communications in terms of the efficacy and attainability of suitable adaptations, rather than simply highlighting drought risks or providing drought warnings, to best enable farmers to build drought resilience.
