摘要

背景:叙利亚是一个发展中国家,其经济仍以农业部门为主。农业部门被认为是叙利亚的主要粮食来源,也是就业和创收的主要来源。叙利亚的粮食和农业政策主要侧重于实现粮食安全并改善其四大支柱(可得性、可及性、稳定性和利用率)。因此,到2011年,在粮食供应方面取得了良好进展。2011年危机后,叙利亚的粮食安全形势恶化,面临严重粮食不安全的人数从2020年的790万增加到2021年的惊人的1240万。这是农业部门所遭受的许多冲击的结果,例如耕地面积相对减少、生产成本高、包括劳动力在内的投入物减少、普遍存在的暴力、对农业设备的相关损坏和废弃土地。鉴于叙利亚农业部门因危机而面临的变化,该研究涉及衡量叙利亚一些雨养谷物和豆类作物的生产技术效率,并在2011年开始的危机前后进行比较。采用非参数(DEA)方法对2003-2010年(危机前)和2011-2018年(危机后)期间的技术效率进行了测量,并采用审查回归(tobit模型)来研究技术效率的决定因素。采用t检验检验零假设(H0)在叙利亚危机前后所研究作物的生产技术效率没有差异,替代假设(Ha)在技术效率上有显著差异。结果:后危机时期技术效率水平较低。研究结果验证了危机前后技术效率的差异。采用危机假人剔除回归对硬粒小麦和扁豆作物的技术效率均有显著负向影响,而对其他作物的技术效率无显著影响。结论:本研究可为政府制定恢复和提高农业生产和生产力的新政策提供重要信息。迫切需要采取新的政策,侧重于以低息贷款的形式提供生产需求,可持续地利用资源,为销售过程提供支助,并侧重于一些研究作物(鹰嘴豆和扁豆)的出口市场。政府应改善对农民的农业推广服务,鼓励他们采用新技术。

Evaluation of technical efficiency of some rain-fed cereal and legume crops production in Syria: does crisis matter?

Background: Syria is a developing country whose economy is still dominated by the agricultural sector. The agricultural sector is considered as the main source of food in Syria and a major source of employment and income generation. Food and agricultural policies in Syria focus heavily on achieving food security and improving its four pillars (availability, accessibility, stability and utilization). As a result, until 2011, a good progress has been attained in food availability. The food security situation deteriorated in Syria after 2011 crisis, with the number of people facing acute food insecurity rising from 7.9 million in 2020 to a staggering 12.4 million in 2021. This is the result of many shocks that the agricultural sector has been exposed to, such as the relative decrease in cultivated areas, high costs of production, reduced input availability including labour, prevailing violence, related damage to farm equipment, and abandoned land. In view of the changes that the agricultural sector has been exposed to in Syria as a result of the crisis, the study concerns measuring the technical efficiency of production of some rain-fed cereal and legume crops in Syria and comparing it in the pre and post-crisis period, which has started in 2011. A non-parametric (DEA) method is applied for measuring technical efficiency during the time period 2003-2010 (pre-crisis) and the period 2011-2018 (post-crisis) with censored regression (the tobit model) to investigate the determinants of technical efficiency. A t test is used to test the null hypothesis (H0) that there was no difference in technical efficiency of the production of studied crops before and after the crisis in Syria and the alternative hypothesis (Ha) that there was a significant difference in technical efficiency.

Results: The findings show low level of technical efficiency in the post-crisis period. The results verified differences in the technical efficiency of pre- and post-crisis period. The use of censored regression with dummy for crisis has shown negative and significant effect on technical efficiency of each of the durum wheat and lentil crops, while it had no significant effect on the other studied crops.

Conclusions: This study can provide important information to the government to pursue a new policy for recovery and improving the agricultural production and productivity. There is an urgent need to adopt new policies that focus on providing production requirements in the form of low-interest loans, sustainable use of resources, providing support for the marketing process, and focusing on the export markets of some study crops (chickpeas and lentils). Government should improve agricultural extension services for farmers and encouraging them to adopt new technologies.

期刊介绍: Agriculture & Food Security is a peer-reviewed open access journal that addresses the challenge of global food security. It publishes articles within the field of food security research, with a particular focus on research that may inform more sustainable agriculture and food systems that better address local, regional, national and/or global food and nutritional insecurity. The journal considers cutting-edge contributions across the breadth of relevant academic disciplines, including agricultural, ecological, environmental, nutritional, and socio-economic sciences, public health and policy. The scope of the journal includes, but is not limited to: -Agricultural and environmental sciences, including genetics and systems ecology- Animal husbandry, fisheries science and plant science- Global change, biodiversity, climatology and abiotic stresses- Food technology and balancing agricultural outputs across food, feed, fibre and fuel- Economics, information sciences and decision theory- Strategies for the implementation of new policies and practices- Public health in relation to the condition of food and nutritional security. The pioneering advances in research reported in Agriculture & Food Security have far reaching implications both for the developing world and for sustainability in the developed world. The published articles are accessible not only to researchers, but are also of special interest to the wider community of farmers, development and public health workers, policy makers and the general public.
