Survey data for ex-post evaluation of the horticulture project in the Marshall Islands

This Data provides supplementary information about how we explored aid effectiveness of the horticulture project in the Marshall Islands. The issue of sustainable development in small island developing countries has become increasingly important. We used a quasi-experimental design and selected the participants (using household as a unit) of the project to the experimental group and non-participants to the control group to evaluate the impact of the horticulture project. As for data collection in the field, we collected data through a structured questionnaire. We recruited one interviewer to conduct household surveys in the field for 40 days from April to June. A total of 96 valid questionnaires were collected, including 36 participants and 60 non-participants. The average household consumption of vegetables and fruits is 6.18 units (SD=7.84). Comparing project participants with non-participants, consumption of vegetables and fruits of the participants is 1.96 units higher than non-participants (P=0.062). Results from regression analysis indicate that participation in the project significantly affects consumption of vegetables and fruits (p&lt; .05). Also, the revenue of selling vegetables and fruit accounts for 74.77 percent of participants' household income, becoming an important source of income for the households.本数据集提供了我们探究马绍尔群岛园艺项目援助成效的相关补充信息。当前，小岛屿发展中国家的可持续发展议题愈发重要。本研究采用准实验设计（quasi-experimental design），以家庭为调研单位，将项目参与家庭纳入实验组，未参与家庭设为对照组，以此评估该园艺项目的实施效果。在实地数据采集阶段，我们通过结构化问卷（structured questionnaire）开展调研：于4月至6月期间招募1名访调员进行入户调查，历时40天，最终回收有效问卷共96份，其中参与组36份、非参与组60份。样本家庭的蔬果平均消费量为6.18单位（标准差Standard Deviation，SD=7.84）；对比两组家庭可知，参与组的蔬果消费量较非参与组高出1.96单位（P=0.062）。回归分析（regression analysis）结果显示，参与该项目对蔬果消费量具有显著影响（p<0.05）。此外，参与项目家庭的蔬果销售收入占其家庭总收入的74.77%，已成为该类家庭的重要收入来源。
