“…Several authors have employed choice experiment in empirical works. For example, Krah et al (2019) used choice experiment to examine the constraints and drivers of soil fertility management (SFM) practice adoption. Waldman et al (2017) evaluate farmers' preference for perennial attributes of pigeon pea intercropped with maize in Malawi.…”

“…where X j is a vector of cowpea attributes associated with alternative j (yield, maturity, colour, size, and price); Z ij is a vector interaction between farmer-specific characteristics (participation in training and being a model farmer) and choice variables; 1 ij is the random error term that is unobserved by the researcher. Refer to Krah et al (2019) and Campbell et al (2018) for more detailed exposition on the conceptual framework.…”

“…more frequent way of evaluating preference heterogeneity is the estimation of the RPL model that allows random taste variation within a sample based on a specified distribution (McFadden & Train, 2000). We specify the subjective expected utility following Krah et al (2019) and Asrat et al (2010) where key socio-economic characteristics enter the utility framework through interaction with the attributes. The subjective expected utility of farmer i choosing cowpea traits j is specified as:…”

Farmers’ preferences for climate-smart cowpea varieties: implications for crop breeding programmes

Despite sustained efforts to promote climate-smart technologies in Sub-Saharan Africa (SSA), adoption remains low. At the same time, the downside risks associated with climate change and food insecurity are becoming acute. Improved cowpea varieties are climate-smart and contribute to food and nutrition security. Limited evidence exists, however, regarding how cowpea attributes influence adoption. We use a discrete choice experiment to investigate farmers' preferences and mean willingness to pay (WTP) for cowpea variety attributes. Our results show that farmers' decision to adopt improved cowpea varieties increases in response to the following attributes: higher yields, early maturity, and white seed coat colour. The results indicate that 86% of the sampled farmers prefer climate-smart cowpea. Secondly, while we observe a wide dispersion of WTP among female cowpea farmers relative to male cowpea farmers, participation in cowpea training reduces the dispersion of WTP for both men and women. Moreover, controlling for farmer risk aversion further decreases the dispersion of WTP for all respondents. Our experiment reemphasizes the need for crop breeding programmes to be participatory. Moreover, such programmes would do well to satisfy the demands of different segments of the population based on risk, gender, and geographical characteristics.

“…In this study, a technical training variable, which measures the number of technical training sessions received by farmers in 2018, is employed as an identifying instrument. Previous studies have shown that participation in soil‐improving practice training stimulates farmers’ adoption behaviour (Chesterman et al ., 2019; Krah et al ., 2019). It is envisaged that OSA adoption is conditional on farmer’s perception of the consequences of chemical fertiliser overuse and the importance of investing in organic soil amendments.…”

“…Soil depletion, occurring both nationally and globally, has posed a wide range of threats to the environment, sustainable agriculture development and food security (Abdulai and Huffman, 2014; Donkor et al ., 2019; Krah et al ., 2019; Fontes, 2020). For example, land degradation may cause climate change when soil carbon and nitrous oxide on the degraded land is released into the atmosphere.…”

Adoption of organic soil amendments and its impact on farm performance: evidence from wheat farmers in China*

This study examines the determinants of adoption of organic soil amendments (OSAs) such as organic fertiliser and farmyard manure and its impact on crop yields and net returns, using household survey data of 558 wheat farmers in China. We employ an endogenous switching regression model to account for selection bias stemming from both observable and unobservable factors. The empirical results show that household size, dependency ratio, machine ownership and non-paid labour are main factors that determine farmers' decision to adopt OSA, and the OSA adoption has a positive and statistically significant impact on wheat yields and net returns. In particular, the treatment effects of OSA adoption are to increase wheat yields and net returns by appropriately 22 and 24 per cent, respectively. Moreover, disaggregated analysis by farm size reveals that large-scale households tend to obtain higher wheat yields and net returns than their small-scale counterparts.
