Clustering for global market access in Bangladesh: Endline survey

The \"Clustering for Global Market Access Survey\" was conducted to assess the impacts of shrimp farm clustering interventions implemented by the Department of Fisheries (DoF), the Bangladesh Shrimp and Fish Foundation (BSFF), and a private sector actor. The survey was carried out in two rounds: a baseline in 2023 and an endline in 2024, to evaluate the effectiveness of these interventions. The data presented here are from the endline survey conducted between May 7 and May 31, 2024. Data were collected at the household, cluster, and community levels using a two-stage simple random sampling design and analyzed through a difference-in-differences approach. Household Data: The household datasets include 1,222 shrimp farms across three districts in southern Bangladesh—Bagerhat, Khulna, and Satkhira. Among these, 622 are cluster farmers, and 600 are non-cluster comparison farmers situated in either the same or adjacent villages to cluster farmers. The data encompass cluster participation, pond characteristics, inputs received from cluster operators, stocking and harvesting, feed and non-feed input use, sales revenue, integrated farming, labor use, credit access, dietary diversity, and food security. Cluster Data: The cluster datasets cover 68 shrimp farm clusters, providing insights into cluster composition and training delivered to cluster members. Community Data: The community datasets provide contextual information on the 136 villages where both cluster and non-cluster farmers reside.‘全球市场准入集群化调查’（Clustering for Global Market Access Survey）旨在评估由孟加拉国渔业部（Department of Fisheries, DoF）、孟加拉国虾类与渔业基金会（Bangladesh Shrimp and Fish Foundation, BSFF）及一家私营机构推行的虾塘集群化干预措施的实施效果。本次调查分为两轮开展：2023年基线调查与2024年终线调查，用于评估上述干预措施的有效性。本次展示的数据均采集自2024年5月7日至5月31日开展的终线调查。本数据集采用两阶段简单随机抽样设计，在家庭、集群与社区三个层面采集数据，并通过双重差分法（difference-in-differences）进行分析。家庭数据集：涵盖孟加拉国南部巴盖尔哈德（Bagerhat）、库尔纳（Khulna）与萨德基拉（Satkhira）三个专区的1222个虾塘，其中622个为集群养殖户，剩余600个为非集群对照养殖户，其居住村落与集群养殖户的村落相同或相邻。该数据集包含集群参与情况、虾塘特征、从集群运营方获取的生产投入物资、苗种投放与收获、饲料及非饲料投入品使用、销售收入、综合种养模式、劳动力使用、信贷获取、膳食多样性与粮食安全状况等内容。集群数据集：覆盖68个虾塘集群，可用于解析集群构成情况以及面向集群成员开展的培训内容。社区数据集：提供了集群养殖户与非集群养殖户共同居住的136个村落的相关背景信息。
