What happens after the boom? Aquaculture, land use change, and smallholder resilience in Central Thailand

Abstract

There has been a proliferation of research on Southeast Asian crop booms over the past 15 years. Most studies take place at the height of booms or examine the immediate trajectory of boom and subsequent ‘bust’. Few take a longer-term perspective. In this article we draw on the literature on crop booms and scholarship on ‘everyday’ forms of agrarian transformation to address the question of what happens to livelihoods and land use patterns after a crop boom has ended. We pose this question with reference to aquaculture (shrimp and fish farming) in Central Thailand, which has undergone a series of booms and busts since the 1980s. We address the question using integrated mixed methods (geospatial analysis of land use change, surveys of 455 farm households in 8 provinces, in-depth interviews with 40 farmers). The post-boom trajectory of aquaculture and associated livelihoods has been characterized by the attenuation of boom/bust cycles, continuous adaptation and diversification by producers in the face of successive overlapping shocks, and a surprising degree of continuity and persistence in land use, landholdings and livelihoods. This pattern reflects historical legacies including high levels of absentee landlordism and secure agricultural tenancy and land tenure. Intra-household division and reconsolidation of inherited land, the relatively high economic value and environmental plasticity of key species farmed, and Thailand's ‘middle-income trap’ status all contribute to the persistence of aquaculture after the boom.
