Seaweed harvest has denuded many areas of the sea floor, threatening marine ecosystems and the livelihood of coastal communities. Recently, small operators have begun to cultivate seaweed. This paper studies the role of fishing and agriculture, and their interactions with risk and time preferences, in the uptake of seaweed aquaculture. We use a Heckman selection model to study the decision to participate and expansion of production in seaweed aquaculture in Chile. We find that experience with seaweed farming, ecological benefits, and perception of well-suited areas increase participation in seaweed aquaculture. In addition, more contacts within the industry, a surveillance system against theft, and a shorter authorization period to farm increase seaweed production. Among land farmers, while more risk-tolerant producers participate more in seaweed aquaculture, more patient producers cultivate higher levels. We argue that policy design should consider the particularity of other sectors that are synergetic with aquaculture.

渔民和土地农民向小规模海藻养殖的转型模式:风险和时间偏好的作用

海藻的收获已经侵蚀了海底的许多区域,威胁着海洋生态系统和沿海社区的生计。最近,小经营者开始种植海藻。本文研究了渔业和农业在海藻养殖中的作用,以及它们与风险和时间偏好的相互作用。我们使用 Heckman 选择模型来研究参与和扩大智利海藻养殖生产的决定。我们发现海藻养殖的经验、生态效益和对适宜区域的认知增加了海藻养殖的参与度。此外,行业内更多的联系、防盗监控系统以及更短的养殖授权期可以增加海藻产量。在土地农民中,虽然更具风险承受能力的生产者更多地参与海藻养殖,但更多耐心的生产者养殖的水平更高。我们认为政策设计应考虑与水产养殖协同的其他部门的特殊性。
