Abstract The notion of convergent and transdisciplinary integration, which is about braiding together different knowledge systems, becoming the mantra numerous initiatives aimed at tackling pressing water challenges. Yet, transition from rhetoric to actual implementation impeded by incongruence in semantics, methodologies, discourse among disciplinary scientists societal actors. Here, we embrace “integrated modeling”—both quantitatively qualitatively—as a vital exploratory instrument advance such providing means navigate complexity manage uncertainty associated with understanding, diagnosing, predicting, governing human‐water systems. From this standpoint, confront barriers offering seven focused reviews syntheses existing missing links across frontiers distinguishing surface groundwater hydrology, engineering, social sciences, economics, Indigenous place‐based knowledge, studies other interconnected natural systems as atmosphere, cryosphere, ecosphere. While there are, arguably, no bounds pursuit inclusivity representing spectrum human processes around resources, advocate that integrated modeling can provide approach delineating scope through lens three fundamental questions: (a) What “purpose”?

More broadly, call for investigating what warranted “systems complexity,” opposed unjustified “computational complexity” when complex human‐natural careful attention interdependencies feedbacks, scaling issues, nonlinear dynamics thresholds, hysteresis, time lags, legacy effects.

Abstract The Latin America and the Caribbean (LAC) region plays key roles in both meeting global agricultural demands maintaining carbon sinks due to its abundant land water resources. In this study we use Global Change Analysis Model evaluate opportunities challenges posed by two global‐scale drivers: market integration (i.e., reduction of trade barriers) land‐based climate mitigation policy. We their potential individual combined impacts on production revenues across LAC's economies through mid‐century, as well resulting consumers integrated land‐water‐climate systems diverse sub‐regions. Increased results increased for many LAC economies, driven evolving comparative advantages. Climate measures CO 2 non‐CO greenhouse gases increase prices from competition emissions abatement. outcomes drivers are complex sometimes non‐linear, highlighting importance understanding interactions between multiple drivers. Our show that opportunities, either drivers, pose significant trade‐offs require careful multi‐sectoral planning, such challenges, loss livestock when pursuing strategies, consumer expenditures, changes land‐use or withdrawals, deforestation scarcity pressures. There is considerable heterogeneity economic environmental sub‐regions commodities, illustrating value considering at finer scales.

Our results show that, business-as-usual conditions, wind solar contribute more than half new generation capacity by 2050, though this requires substantial expansion natural gas-based capacity. While hydropower appears be less cost-competitive, existing high provides critically important flexibility integrate avoid further reliance expensive or polluting resources (e.g., gas).
