Farmer Willingness to Pay for Qualiity Cowpea Seeds, Burkina Faso 2017 Survey

Increasingly erratic weather/climatic conditions and the corresponding effects on crop yields are accentuating the need for farmers to plant good quality seeds of improved varieties. However, for self-pollinated crops like cowpeas (Vigna ungiculata), for which “seed” is highly competitive with “grain” when used as planting material, the demand for seeds of good quality is often negatively affected by several factors, including, the price of quality seeds and the common practice of “recycling” grains as seed. This dataset include farmer survey data on their willingness to pay (WTP) for three types of seed products (Certified, Quality Declared, and own-saved/recycled) in Burkina Faso using the Becker-DeGroot-Marschak (BDM) bidding mechanism.The objective of this survey and the BDM experiment was to understand i) how the perceived differential performance of different types of seeds translate into farmers' WTP for these seeds; and ii) the factors which determine the WTP for each type of “seed” product. Dataset also includes data collected from farmers to understand their household and farm characteristics and prior experience with growing different types of cowpea seeds. Dataset is recorded in French language.

日趋多变的天气与气候条件，及其对作物产量的连带影响，愈发凸显出农户种植改良品种优质种子的必要性。然而，对于豇豆（Vigna ungiculata）这类自花授粉作物而言，其用作种植材料的“种子”与“籽粒”存在极强的竞争性，因此优质种子的需求往往受到多重因素的负面影响，其中包括优质种子的价格，以及农户普遍将收获籽粒留作种子的常见做法。本数据集收录了布基纳法索地区农户针对三类种子产品（Certified、Quality Declared以及own-saved/recycled）的支付意愿（WTP）调查数据，调查采用贝克尔-德格鲁特-马夏克（BDM）竞价机制。本次调查与BDM实验的目标在于：其一，厘清农户对不同类型种子的差异化性能认知，如何转化为其对各类种子的支付意愿；其二，明确决定农户对每一类“种子”产品支付意愿的影响因素。本数据集同时收录了针对农户的调研数据，用于了解其家庭与农场特征，以及此前种植不同类型豇豆种子的相关经验。本数据集以法语记录。
