The Impact of Climatic Change Adaptation on Agricultural Productivity in Central Chile: A Stochastic Production Frontier Approach

Abstract

Adaptation to climate change is imperative to sustain and promote agricultural productivity growth, and site-specific empirical evidence is needed to facilitate policy making. Therefore, this study analyses the impact of climate change adaptation on productivity for annual crops in Central Chile using a stochastic production frontier approach. The data come from a random sample of 265 farms located in four municipalities with different agro-climatic conditions. To measure climate change adaptation, a set of 14 practices was used in three different specifications: binary variable, count and index; representing decision, intensity and quality of adaptation, respectively. The aforementioned alternative variables were used in three different stochastic production frontier models. Results suggest that the use of adaptive practices had a significant and positive effect on productivity; the practice with the highest impact on productivity was irrigation improvement. Empirical results demonstrate the relevance of climate change adaptation on farmers' productivity and enrich the discussion regarding the need to implement adaptation measures.

“…This implies that the dominance of small farms in the area under investigation may tremendously improve productivity in the region. However, Roco, et al [80] cautions that this may pose a threat to productivity.…”

Climate Change Impacts and Adaptation Strategies of Agriculture in Mediterranean-Climate Regions (MCRs)

“…For example, in Nepal, small-holders adopting a larger number of adaptation practices were on average 13% more efficient than those adopting fewer practices [120]. Also, in Central Chile, adaptation practices, in particular improvements in irrigation, had positive effects on productivity [121]. This highlights the relevance of CC adaptation to farmers' productivity and enriches discussions of the need to implement adaptation practices.…”

“…This highlights the relevance of CC adaptation to farmers' productivity and enriches discussions of the need to implement adaptation practices. However, despite the specific and global impacts, the rate of adaptation to CC is still low [121,122]. In addition, it has been noticed that there is a divergence between the adaptation practices recommended by experts and those adopted by farmers.…”

Selain tren ini, intensifikasi perubahan iklim akan terus mengubah kondisi pertumbuhan, seperti suhu, curah hujan, dan kelembaban tanah, dengan cara yang kurang dapat diprediksi [2].…”
