Agricultural Economics (Amsterdam, Netherlands), GIS-derived measures of location and space have increasingly been used in models of land use and ecology. However, they have made few inroads into the literature on technology adoption in developing countries, which continues to rely mainly on survey-derived information. Location, with all its dimensions of market access, demographics and agro-climate, nevertheless remains key to understanding potential for technology use. The measures of location typically used in the adoption literature, such as locational dummy variables that proxy a range of locational factors, now appear relatively crude given the increased availability of more explicit GIS-derived measures. This paper attempts to demonstrate the usefulness of integrating GIS-measures into analysis of technology uptake, for better differentiating and understanding locational effects. A set of GIS-derived measures of market access and agro-climate are included in a standard household model of technology uptake, applied to smallholder dairy farms in Kenya, using a sample of 3330 geo-referenced farm households. The three technologies examined are keeping of dairy cattle, planting of specialised fodder, and use of concentrate feed. Logit estimations are conducted that significantly differentiate effects of individual household characteristics from those related to location. The predicted values of the locational variables are then used to make spatial predictions of technology potential. Comparisons are made with estimations based only on survey data, which demonstrate that while overall explanatory power may not improve with GIS-derived variables, the latter yield more practical interpretations, which is further demonstrated through predictions of technology uptake change with a shift in infrastructure policy. Although requiring large geo-referenced data sets and high resolution GIS layers, the methodology demonstrates the potential to better unravel the multiple effects of location on farmer decisions on technology and land use.
14 pages., his paper evaluates the effect of the Rural Capacity Building Project (RCBP),
which aimed at promoting growth by strengthening the agricultural service systems
in Ethiopia, and by making them more responsive to smallholders’ needs, in particular women farmers. We examine the gender-differentiated impact of the RCBP
using panel data on 1,485 geographically dispersed households in project and control
kebeles. We find that women farmers’ access and satisfaction with extension services
increased significantly immediately after the start of the project, but that effect did
not last into the medium term. The project led to an increase in the adoption of high-
value crop farming, area of land cultivated, and economic participation of household
members, benefiting male- and female-headed households equally. Results point to
the positive impact of incorporating women’s needs and constraints in the design of
the agricultural extension system. However, the project was not able to reduce the
preexisting gender gap in agricultural outcomes.
