Abstract
The paper investigates the attitude of farmers to participate in an on-farm conservation programme based on the cultivation of vine landraces in Apulia, southern Italy, in place of the current commercial varieties, as an adaptation strategy to climate changes. The results, based on choice experiments and assessed through a latent class model, highlight a general interest of the regional farmers toward the biodiversity-based adaptation programme for coping with climate change. In particular, three classes of respondents were identified: (i) farmers operating on the whole regional territory and willing to cultivate up to 50% of their farm area with up to two landraces and compensation in line with the aid set by the regional rural programme; (ii) winegrowers of the intensive rural areas and willing to cultivate up to 25% of their farm with up to two landraces and a compensation greater than 200% compared to the aid of the regional rural programme; (iii) farmers operating in the intermediate rural areas and willing to cultivate up to 50% of their farm with up to three landraces and a compensation greater than 50% compared to the aid of the regional rural programme. Policymakers should calibrate adaption actions depending on rural areas, since economic, social, cultural, behavioural and cognitive barriers, as well as structural characteristics of farms, impact the farmers’ attitudes toward measures aimed at coping with climate change.
Highlights
Agriculture is one of the major sources of greenhouse gases (GHGs) but, at the same time, is one of the most susceptible sectors to the adverse impacts of climate change [1,2,3,4]
Motivation was investigated by asking them to select a statement among a set of five assertions at the end of section two. The two statements these respondents selected to explain their behaviour or preferences were (1) I do not believe in climate change (2) and (2)
A three-class latent class model (LCM) was selected since the LL, Akaike Information Criterion (AIC), Bayesian Information Criterion (BIC), and AIC3 were minimised at three segments (Table 4)
Summary
Agriculture is one of the major sources of greenhouse gases (GHGs) but, at the same time, is one of the most susceptible sectors to the adverse impacts of climate change [1,2,3,4]. Alterations in climate affect abiotic (drought, excessive temperature and salinity in flooded areas) and biotic factors (diseases, pests, vectors, and weeds), which influence crop productivity. Genetic diversity is crucial for breeding programs aimed at producing crops and livestock that are suitable to new climate conditions. Contrasting the effects of climate change and preserving agrobiodiversity are two of the nine specific objectives aimed at fostering a sustainable and competitive agricultural sector, so as to contribute to the “Farm to Fork”
