“…Previous studies investigating the effects of information technology adoption or policy programme intervention have used a propensity score matching (PSM) method (e.g. Fentie and Beyene 2019;Hou et al 2019) and an inverse-probability weighted regression adjusted (IPWRA) estimator (Manda et al 2018;Adolwa et al 2019;Tambo and Mockshell 2018). For example, using the PSM approach, Fentie and Beyene (2019) have analysed the impact of row planting technology on the welfare of rural households in Ethiopia.…”

“…Different terminologies of SAPs have been used by scholars, including such as conservation tillage, legume intercropping, crop rotation, uses of improved varieties, the application of farmyard manure and organic fertiliser, adoption of soil and water conservation technology, conservation agriculture technology and integrated pest management (IPM) technology (e.g. Adolwa et al 2019;Kassie et al 2013;Ma and Abdulai 2019;Midingoyi et al 2019;Ndiritu et al 2014;Rodriguez et al 2009;Tambo and Mockshell 2018;Teklewold et al 2013;Wossen et al 2015;Zeweld et al 2017).…”

“…Midingoyi et al (2019) find that the adoption of IPM technologies significantly increases mango yields and net income but reduces insecticide use in Kenya, contributing to an improvement of environment and human health. In their investigation on Ghana and Kenya, Adolwa et al (2019) reveal that adoption of interpreted soil fertility management leads to an increase in maize yields.…”

“…Despite the multiple benefits associated with the SAP adoption, the adoption rate of SAPs is still low in rural areas of developing countries (Adolwa et al 2019;Midingoyi et al 2019). A better understanding of constraints and incentives that determine farmers' adoption behaviour for SAPs is, therefore, of importance for designing agri-environmental policies that could stimulate their SAP adoption and enhance farm economic performance.…”

“…Previous studies have used either a propensity score matching technique or an inverseprobability weighted regression adjusted estimator to estimate the effects of a binary treatment variable (e.g. Adolwa et al 2019;Fentie and Beyene 2019;Hou et al 2019;Manda et al 2018;Tambo and Mockshell 2018). However, the two approaches fail to address the selection bias arising from unobserved factors.…”

Relatively little is known about the association between Internet use and environmentally-friendly agricultural innovation adoption. To fill this void, this study examines the impact of Internet use on the adoption of sustainable agricultural practices (SAPs) and their heterogeneous effects on farm income and household income. Unlike previous studies that analyse the dichotomous decision of agricultural innovation adoption, this study captures the number of SAPs adopted. We apply both endogenous-treatment Poisson regression model and unconditional quantile regression model to analyse unique farm-level data collected from China. The empirical results show that Internet use exerts a positive and statistically significant impact on the number of SAPs adopted, and the joint effects of Internet use and SAP adoption on farm income and household income are heterogeneous. In particular, we show that Internet use has a larger impact at the upper tail of household income but it has no significant impact on farm income. SAP adoption is negatively associated with farm income and household income across the selected quantiles.

Does nutrition knowledge training improve dietary diversity and nutrition intake? Insights from rural China

Improving dietary diversity and nutrition intake among rural households is essential to promote sustainable rural development. In this study, we examine whether nutrition knowledge training increases rural households' dietary diversity, nutrition intake, and total calorie intake. We consider three macronutrients (proteins, fats, and carbohydrates) and three micronutrients (vitamin C, iron, and zinc) to capture nutrition intake. The doubly robust inverse probability weighted regression adjustment estimator is employed to estimate survey data of 765 rural households collected by the Institute of Food and Nutrition Development, Ministry of Agriculture and Rural Affairs of China. The results show that nutrition knowledge training enhances household dietary diversity, improves the intake of macronutrients in terms of proteins and fats and micronutrients in terms of zinc, and increases total calorie intake. In addition, the intake of nutrients and calories of males responds to nutrition knowledge training while that of females does not. The dietary diversity of females increases with nutrition knowledge training, whereas that of males is unaffected. {EconLit Citations: I12, I18, Q12, E24}.

The role of active soil carbon in influencing the profitability of fertilizer use: Empirical evidence from smallholder maize plots in Tanzania

2021

We use recent plot-level panel data from Tanzanian smallholder farmers to investigate maize yield responses to inorganic fertilizer under variable soil carbon conditions. Unlike many prior studies which consider total carbon measurements, we focus on active soil carbon, which is a component strongly related to key soil functions, such as nutrient cycling and availability. Active soil carbon is found to be a strong predictor of maize yield response to nitrogen fertilizer. These results highlight important sources of variation in the returns to fertilizer investments across plots and smallholder farmers in the region. When farmgate prices for maize and fertilizer are
