21 pages, Despite decades of investment in agricultural extension, technology adoption among farmers and agricultural productivity growth in Sub-Saharan Africa remain slow. Among other shortcomings, extension systems often make recommendations that do not account for price risk or spatial heterogeneity in farmers' growing conditions. However, little is known about the effectiveness of extension approaches for nutrient management that consider these issues. We analyze the impact of farmers' access to site-specific nutrient management recommendations and to information on expected returns, provided through a digital decision support tool, for maize production. We implement a randomized controlled trial among smallholders in the maize belt of northern Nigeria. We use three waves of annual panel data to estimate immediate and longer term effects of two different extension treatments: site-specific recommendations with and without complementary information about variability in output prices and expected returns. We find that site-specific nutrient management recommendations improve fertilizer management practices and maize yields but do not necessarily increase fertilizer use. In addition, we find that recommendations that are accompanied by additional information about variability in expected returns induce larger fertilizer investments that persist beyond the first year. However, the magnitudes of these effects are small: we find only incremental increases in investments and net revenues over two treatment years.
12 pages, via online journal, Since the rice crisis of 2007, the government of Benin has initiated many programmes for rice intensification. Comparison of three rice production areas shows that local rice production has indeed been increased by the facilities provided by the government programmes. Although broadly the same facilities (market outlet, credit, input, etc.) were provided to rice farmers in the three study areas, which are located close to one another, there are not only similar, but also some different outcomes with regard to farmers' practices. There were also some unexpected changes, like the shift from limited collective canal cleaning to individual canal cleaning in Koussin-Lélé and the use of pumps in upland areas in Bamè. The study explores the interplay between these external interventions of government programmes and local actions of farmers to explain the outcomes. Using an actor-oriented perspective, the study concludes that farmers' agency played a critical role in the success of interventions; the changes occurred because of local actions of the farmers and intermediaries interacting with the external interventions at diverse junctures. Differences in strategies for resolving livelihood problems, in production options and biophysical conditions influence farmers' local actions and contribute to the explanation of the diversity of outcomes. The main lesson drawn from this research is that evaluation studies should not consider external interventions as the only or primary source of change. The dynamic interplay between local agency, intermediation and external interventions makes room for change.
18 pages, Based on panel data from the Rural Fixed Point Survey of the Ministry of
Agriculture over the period 2004-2016 and supplementary survey data on information
and communications technology (ICT) applications in the countryside, this paper employs
the difference in differences (DID) method to analyze the effects of ICT applications on
rural households’ agricultural total factor productivity (TFP) with mobile phone signal,
internet and 3G mobile network connections as indicators, and decomposes and evaluates
the constituent factors. Our findings reveal a positive effect of ICTs on rural households’
TFP, which primarily stemmed from rising agricultural technical efficiency. However, ICTs
exerted no significant effect on agricultural technical progress during this paper’s data
period due to limited rural human capital. These findings are consistent with robustness test
results based on counterfactual and matching methods.
AGE 85925422, Data from 358 households in 12 sites representative of climatic, geographical, and agricultural variations in the eastern communal areas of Botswana show that differences in the agricultural practices and extension contact of male- and female-headed households largely disappear when economic stratum is controlled. Female-headed households are shown not to be a homogeneous group. There appear to be greater similarities between farmers within the same economic stratum regardless of gender than between farmers of the same gender in different strata.
