The agricultural sector faces a series of environmental challenges such as water and soil pollution, erosion or biodiversity loss, especially in monoculture systems. Alternatively, crop diversification is seen as an option to reduce negative impacts and to enhance agricultural Ecosystem Services (ES). Most of these ES, such as improving resilience, despite the benefits and the high social value, do not take part in the market. In this context, the present paper presents an analysis of social preferences regarding crop diversification practices in Mediterranean agroecosystems. To do so, a choice experiment has been developed to assess social demand for more welfare-improving agricultural cropping systems. Benefits were obtained from improving environmental and cultural ES provision due to intercropping, as crop diversification practices. The results show a strong social preference for crop diversification with regard to all the benefits considered in the experiment. In fact, the total economic value for non-market goods and services provided by intercropping, which ranges from 900 to 1400 €/ha/year, for some crops might be potentially higher than cropland financial benefits. These results highlight the social support for a change in agricultural model to reach sustainable agroecosystems, which is essential to ensure the success of agrarian and rural development policies.

通过间作地中海农业生态系统评估多样化收益：一种选择实验方法

农业部门面临着一系列环境挑战，例如水和土壤污染、侵蚀或生物多样性丧失，特别是在单一栽培系统中。或者，作物多样化被视为减少负面影响和加强农业生态系统服务 (ES) 的一种选择。这些ES中的大多数，例如提高弹性，尽管有好处且具有很高的社会价值，但并未参与市场。在此背景下，本文对地中海农业生态系统中作物多样化实践的社会偏好进行了分析。为此，开发了一个选择实验来评估社会对更多改善福利的农业种植系统的需求。由于间作，作为作物多样化实践，改善环境和文化 ES 供应获得了收益。结果表明，就实验中考虑的所有好处而言，社会对作物多样化有着强烈的偏好。事实上，对于某些作物，间作提供的非市场商品和服务的总经济价值为 900 至 1400 欧元/公顷/年，可能高于农田经济收益。这些结果强调了改变农业模式以实现可持续农业生态系统的社会支持，这对于确保农业和农村发展政策的成功至关重要。对于某些作物而言，其经济效益可能高于农田。这些结果强调了改变农业模式以实现可持续农业生态系统的社会支持，这对于确保农业和农村发展政策的成功至关重要。对于某些作物而言，其经济效益可能高于农田。这些结果强调了改变农业模式以实现可持续农业生态系统的社会支持，这对于确保农业和农村发展政策的成功至关重要。
