13 pages., Via online journal., Access to food is a basic pillar of human development. It is therefore unsurprising that it features so centrally on global development agendas and that a robust, interdisciplinary literature seeks to examine its determinants. This study focuses on the relationship between mobile technology and food access. Specifically, we ask whether mobile technology can strengthen the relationship between food access and certain social and political factors such as remittance flows and political participation. We use Afrobarometer surveys and highly disaggregated data on 2G network coverage to estimate a multilevel model testing how increased connectivity measured by mobile technology influences food access. We show that mobile phone use and higher frequency of use are significantly and positively correlated with food access, but we do not find evidence that remittances and political participation levels can explain the mechanisms linking mobile technology and food access. The study highlights that connectivity can play a powerful role in shaping food outcomes even when controlling for commonly identified impediments such as income constraints or physical isolation. These findings suggest that policies aimed at improving food access should devote attention to strengthening both communication and physical infrastructure.
10 pages., Via online resource., Many smallholder farmers in developing countries grow multiple crop species on their farms, maintaining de facto crop diversity. Rarely do agricultural development strategies consider this crop diversity as an entry point for fostering agricultural innovation. This paper presents a case study, from an agricultural research-for-development project in northern Ghana, which examines the relationship between crop diversity and self-consumption of food crops, and cash income from crops sold by smallholder farmers in the target areas. By testing the presence and direction of these relationships, it is possible to assess whether smallholder farmers may benefit more from a diversification or a specialization agricultural development strategy for improving their livelihoods. Based on a household survey of 637 randomly selected households, we calculated crop diversity as well as its contribution to self-consumption (measured as imputed monetary value) and to cash income for each household. With these data we estimated a system of three simultaneous equations. Results show that households maintained high levels of crop diversity: up to eight crops grown, with an-average of 3.2 per household, and with less than 5% having a null or very low level of crop diversity. The value of crop species used for self-consumption was on average 55% higher than that of crop sales. Regression results show that crop diversity is positively associated with self-consumption of food crops, and cash income from crops sold. This finding suggests that increasing crop diversity opens market opportunities for households, while still contributing to self-consumption. Given these findings, crop diversification seems to be more beneficial to these farmers than specialization. For these diversified farmers, or others in similar contexts, interventions that assess and build on their de facto crop diversity are probably more likely to be successful.
