Farmers have a long history of adapting to changing conditions, including changing climate, towards more sustainable agricultural production. In this study, we construct a unique long-duration pseudo-panel dataset from nationally representative households in Vietnam to investigate factors behind farmer's choices to adopt soil and water conservation techniques to adapt to climatic change. Since farmers' adoption decisions are inherently dynamic, a dynamic probit model was estimated. We find that weather shocks and long-run changes in temperature are significant determinants of farmers' choices. The decision to make new investments in adaptation practices in subsequent periods is confirmed to be strongly influenced by the past adoption decision. Farmer's experience, farm size, and access to weather and output price information are also associated with households that apply conservation measures. These findings suggest that policies aiming at promoting climate-resilient strategies should pay attention to farmers' adaptation behavior and the persistence of choices in farmers' decision-making processes. Policies should target improving farmers' access to information with a special focus on market- and weather-related information to enhance farmers' adaptive capacity to better cope with ongoing climatic uncertainty.

农民在适应不断变化的条件（包括不断变化的气候）以实现更可持续的农业生产方面有着悠久的历史。在这项研究中，我们从越南具有全国代表性的家庭中构建了一个独特的长期伪面板数据集，以调查农民选择采用水土保持技术以适应气候变化的背后因素。由于农民的采用决定本质上是动态的，因此估计了动态概率模型。我们发现天气冲击和温度的长期变化是农民选择的重要决定因素。确认在随后的时期对适应做法进行新投资的决定受到过去采用决定的强烈影响。农民的经验，农场规模，获取天气和产出价格信息也与采取保护措施的家庭有关。这些发现表明，旨在促进气候适应战略的政策应该关注农民的适应行为和农民决策过程中选择的持续性。政策应以改善农民获取信息为目标，特别关注与市场和天气相关的信息，以提高农民的适应能力，以更好地应对持续的气候不确定性。
