Addressing gender in agricultural research for development in the face of a changing climate: where are we and where should we be going?

Agricultural development efforts that do not address persistent gender gaps miss opportunities for greater impact. This synthesis reflects on key findings from integrated quantitative and qualitative analyses at the nexus of gender, agricultural development, and climate change. Linked farm household-, intrahousehold-, community-, and institutional-level data highlight significant and nuanced gender differences in adaptive capacity of individuals and communities to respond to climate change. The gender gap is also substantial in exposure to climate change and its impacts, and uptake of new practices that lower vulnerability. Women in agriculture will remain largely neglected by information and service providers unless their differing needs, access to, and control over resources are considered at policy and project design stage. Yet clear guidelines for addressing the needs of both men and women in different environments and agricultural systems are still lacking. Participatory ‘action research’ approaches with a focus on co-learning, and using innovative cell phone or social media-based approaches offer exciting new opportunities. Agricultural development decision-makers and project designers need to ‘design with gender in mind’. Equipping them with tools and knowledge of innovative gender-transformative practices and intervention options and creating accountability for serving women and men will be key.     

Are we overestimating the negative impact of higher food prices? Evidence from Ghana

Most studies of the welfare impact of higher food prices adopt Deaton's approach, based on the first‐order effect of prices changes using income and expenditure survey data. This paper explores the impact of higher maize and food prices in Ghana and considers the sensitivity of results to changes in several assumptions. If second‐order effects are included, incorporating household response to price changes, the welfare impact of food price increases is more positive, but only modestly so. However, if we assume that marketing margins are constant in real terms rather than proportional to prices, the welfare impact is substantially more positive. These findings highlight the need for more research on the behavior of marketing margins under volatile prices.     

Urban expansion in contemporary China: What can we learn from a small town?

Rapid physical expansion of urban land use is widely observed in Chinese cities. Although there is a consensus that economic liberalization and decentralization of administrative responsibilities explain the urban changes, it is not clear whether or not actual economic and population growth is the only cause of urban expansion. By using a small town as a case study, this paper shows that urban expansion is a combined outcome of actual needs, planning preparations, profit-seeking, and more importantly, the approach used by local government to achieve economic ambitions. Findings show that local economic and demographic changes do contribute to land-use expansion, but a local development approach that uses urban expansion to improve the competitive edge of the locality plays a critical role. A pro-growth coalition consisting of top local government officials, state work-unit leaders, and developers, whose interests align for short-term gain in economic and political terms, guarantee the mobilization of resources for carrying out the rapid urban expansion, and a vision of the local economic success. These findings add in a new dimension that is not yet seen in the study of China's urban expansion.     

Can we avoid overdevelopment of river floodplains by economic policies?: A case study of the Ouse catchment (Yorkshire) in the UK

River floodplains are significant environmental resources in that they provide multiple ecosystem services. However, river floodplains are/tend to be overdeveloped because indirect-use values linked with ecosystem services are overlooked by private landowners. In a case study of the Ouse catchment, it turns out that river floodplains tend to be overdeveloped in upstream areas because of a unidirectional spatial externality. We set a simple model that considers both direct- and indirect-use values to analyse the social optimisation. The essential point is that we must consider two types of environmental externalities related to the ecosystem services of river floodplains to make decisions on floodplain development. First, the development of river floodplains has opportunity costs in terms of lost ecosystem services. Second, the development of floodplains increases flood risks to people downstream (imposes a unidirectional spatial external costs). Theoretically, we can easily deal with the problem by zonal economic policies: zonal taxes or subsidies (price policies) and zonal marketable permits or transferable development rights (quantity policies). On the practical side, however, there are so many problems. Then, such approaches are too complex to use. First of all, we have to specify real complicated economic and physical systems which show non-linearity, irreversibility, site-specific relationships, and inter-dependency between systems and sites. Secondly such policies should be ‘zonal’, which might impose substantial transaction costs. In order to apply them to real situations, we have to determine the appropriate number of zones, their sizes and geographical shapes, and then set appropriate rates or amounts of permits in each zone. Furthermore, the determination of zones is difficult because of the trade-off between the internalisation of externalities and implementation costs of policies, which are also related to political frictions and market failure.
