note = {Smallholder farmers, particularly in the Global South, are among the groups experiencing the most direct impacts of weather, climate variability and climate change. These direct impacts might disrupt or reverse development achievements such as poverty reduction and improved food security. Therefore, supporting farmers and other decision-makers in incorporating weather and climate information in their farming decisions (i.e. agro-climate services – ACS) is fundamental to reducing farmers’ vulnerability and safeguarding their farm productivity and income. Despite its importance, ACS delivery at the last mile is a critical gap and faces complex socio-economic and technical barriers. While investments in ACS have increased to pilot ACS innovations in recent years, such projects endure challenges translating experimental evidence to large-scale rolling-out in a real and complex socio-economic landscape. Thus, about 300 million smallholder farmers globally have no or limited access to ACS. As the demand to accelerate ACS access and finance has increased, it is necessary to provide scientific support to decision-makers and stakeholders to make scaling decisions in such a complex and uncertain environment. Therefore, my dissertation aims to understand these dynamics and provide decision support to ACS adoption and scaling processes. To this end, I applied different methodologies as part of a case study in Dien Bien District, Vietnam.
1. In Chapter 2, I describe a novel method to test hypothesized causal relations in ACS delivery pathways using confidence interval interpretation. In two distinct settings, farmer groups experience different pathways to access and uptake ACS while they share a similar high adoption rate. Generating awareness and creating demand, enhancing peer-to-peer exchange and farmers’ attitudes appear to be influential in driving the impact pathway. Adoption of ACS by a critical mass might be sufficient to trigger systemic changes within social groups. Employing a pathway approach can be beneficial in supporting tactical decisions in delivering and outscaling ACS.
2. In Chapter 3, I apply decision analysis to characterize and analyze the socio-economic impacts of upscaling decisions. Across four candidate options for scaling, our simulation results indicate a very high chance (98.35–99.81%) of the ACS interventions providing net benefits. With 90% confidence, investments in ACS would return benefits between 1.45 and 16.02 USD per 1 USD invested. The results demonstrate how decision analysis approaches can be helpful in valuing ACS and provide decision support under uncertainty. I suggest replacing deterministic with probabilistic approaches when analyzing decisions in complex environments.
3. In Chapter 4, I highlight the potential of integrating stakeholder engagement and decision analysis approaches for generating ACS system knowledge and incorporating it in development planning processes. The results show that defining and considering stakeholders’ multi-dimensional attributes are essential for mobilizing their individual knowledge and engagement. I consider in my study nine attributes, including gender, availability, experience, expertise, interest, influence, relevance, attitude as well as individual costs and benefits of each stakeholder. By combining these attributes with stakeholders’ system knowledge and insights about the decision-making process, I am able to explicitly recommend where, when and how stakeholders can support complex and uncertain decisions.
Overall, my research contributes to the advancement of decision-support methods and assists decision-making within and beyond the ACS context. These results and methods provide insights for researchers, governments, civil societies and donors to understand the dynamics, complexity and uncertainty of ACS and inform decision-making for sustainability transition processes.},
