Chitwan Valley Family Study: Labour Outmigration, Agricultural Productivity and Food Security, Nepal, 2015-2017

Dataset 1: Using the Chitwan Valley Family Study (CVFS) surveys and national surveys (Demographic Health Survey and Nepal Living Standard Survey), this survey was designed as a 43-minute Household Agriculture and Migration Survey. This survey includes information on household agricultural practices, including crop production and farm technology use, wealth, assets, income, consumption, food security and information about each household member currently away from home, and remittances received by the household. In addition, an Agriculture and Remittance Calendar was designed to collect retrospective data on farming/non-farming status, crop production, land under cultivation, farm technology use, and migration and remittances from 2006 through July 2015 matching with the agricultural production data collection in 2006. This draft survey was pre-tested in 50 households before data collection was launched. The first wave of the survey was administered to 2,255 households residing within 151 CVFS sample neighborhoods July 15, 2015 through December 20, 2015. These data are part of the Labour Outmigration, Agricultural Productivity and Food Security project data collection, which also includes the Women's Time Use Survey data. Households that participated include the women surveyed in the related data collection. Data from additional waves of the Household Agriculture and Migration Survey will be deposited after data collection is completed. Datasets 2-6: Seasonal Agriculture Survey Data from five additional waves of the Household Agriculture and Migration Survey. Dataset 7-16: To create measures of agricultural productivity, the survey measured yields of major crops grown by farm households. The measures were collected across two seasons in 2015-2017 for lentil, maize, mustard, rice and wheat. Dataset 17: A monthly demographic event registry was administered to all households residing within the 151 CVFS sample neighborhoods from March 2015 through January 2017. The registry monitored outmigration, births, deaths, marriages, and other population events. Dataset 18: A merged data file containing all five waves of the Women's Time Use Survey data (Dataset 19-23) was created. Dataset 19-23: A 16 minute Women's Participation in Farming Survey was designed and administered to women from farm households to collect information on changes in their time and involvement in agriculture and other activities. Survey instruments were used from the International Food Policy Research Institute's modules for the Women's Empowerment in Agriculture Index and Nepal Living Standard Survey (NLSS) as a basis for the Women's Participation in Farming Survey. The instrument was pre-tested to 50 women before finalizing survey content. The Women's Time Use Survey instrument was designed in calendar format to assess the number of hours worked in various household (farming and non-farming) activities in the past 24 hours and the number of days worked in each activity in the past month. Datasets 24-25: These data are the restricted-use version of Dataset 1, which only includes the public-use calendar data. The restricted-use contains both the survey and calendar data.

数据集1：本研究依托奇特旺谷地家庭研究（Chitwan Valley Family Study, CVFS）调研数据与全国性调查数据（人口与健康调查（Demographic Health Survey）、尼泊尔生活标准调查（Nepal Living Standard Survey）），设计了时长43分钟的家庭农业与迁移调查（Household Agriculture and Migration Survey）。该调查涵盖以下信息：家庭农业生产实践数据（含作物种植与农业技术使用情况）、家庭财富、资产、收入、消费与粮食安全状况，以及当前离家的每位家庭成员信息与家庭获得的汇款数据。此外，本研究设计了农业与汇款日历（Agriculture and Remittance Calendar），用于回溯收集2006年至2015年7月的相关数据，包括农业/非农业从业状态、作物种植情况、耕地面积、农业技术使用情况、移民与汇款情况，该回溯数据与2006年的农业生产数据采集工作相匹配。本问卷初稿在正式启动数据采集前，于50户家庭中完成预调研。首轮调查于2015年7月15日至2015年12月20日开展，覆盖151个CVFS抽样社区内的2255户家庭。本数据集隶属于“劳动力外流、农业生产率与粮食安全”项目的数据采集内容，该项目还包含妇女时间使用调查（Women's Time Use Survey）数据。参与本调查的家庭均包含了相关数据采集中受访的妇女。家庭农业与迁移调查后续波次的数据将在全部数据采集工作完成后归档公开。
数据集2至6：为家庭农业与迁移调查额外5个波次的季节性农业调研数据。
数据集7至16：为测算农业生产率，本调研针对农户种植的主要作物产量进行采集。相关测算数据覆盖2015至2017年的两个种植季，涉及小扁豆、玉米、芥菜、水稻与小麦。
数据集17：本研究于2015年3月至2017年1月期间，为151个CVFS抽样社区内的所有家庭建立月度人口事件登记库，用于监测外流、出生、死亡、婚姻及其他人口事件。
数据集18：整合了妇女时间使用调查（Women's Time Use Survey）全部5个波次的数据（数据集19至23），形成合并数据文件。
数据集19至23：本研究设计并针对农户家庭中的妇女开展了时长16分钟的妇女农业参与度调查，用于收集其在农业及其他活动中投入的时间与参与程度变化相关信息。本调查工具以国际粮食政策研究所（International Food Policy Research Institute）开发的妇女农业赋权指数（Women's Empowerment in Agriculture Index）模块与尼泊尔生活标准调查（Nepal Living Standard Survey, NLSS）为基础编制。在最终确定调查内容前，本问卷于50名妇女中完成预调研。妇女时间使用调查工具采用日历式设计，用于评估受访者过去24小时内在各类家庭（农业与非农业）活动中的工作时长，以及过去一个月内参与每项活动的天数。
数据集24至25：本类数据为数据集1的受限使用版本，仅包含公开可用的日历数据；完整受限数据集则同时包含调查数据与日历数据。
