Persistence of open-air markets in the food systems of Africa's secondary cities
In a rapidly urbanizing sub-Saharan Africa (SSA), changing urban food systems are expected to affect the ways in which households access food. While significant research and policy efforts address food production to support food security in the context of city-region food systems, the complex nature of urban food systems has received less attention, particularly in secondary cities across the globe. Using household survey data collected in 2019 a…
Agricultural decision making and climate uncertainty in developing countries
In situations of uncertainty, people often make decisions with heuristic shortcuts or decision rules, rather than using computational or logical methods such as optimizing their behavior based on specific goals. The high level of uncertainty and complexity involved in adapting to climate change suggests that heuristics would be commonly used in this context rather than more structured decision methods. Through a systematic review of 137 articles,…
Has the vision of a gender quota rule been realized for community-based water management committees in Kenya
Cognitive Biases about Climate Variability in Smallholder Farming Systems in Zambia
Given the varying manifestations of climate change over time and the influence of climate perceptions on adaptation, it is important to understand whether farmer perceptions match patterns of environmental change from observational data. We use a combination of social and environmental data to understand farmer perceptions related to rainy season onset. Household surveys were conducted with 1171 farmers across Zambia at the end of the 2015/16 gro…
Maize seed choice and perceptions of climate variability among smallholder farmers
Modeling ecohydrological dynamics of smallholder strategies for food production in dryland agricultural systems
In dryland environments, characterized by low and frequently variable rainfall, smallholder farmers must take crop water sensitivity into account along with other characteristics like seed availability and market price when deciding what to plant. In this paper we use the results of surveys conducted among smallholders located near Mount Kenya to identify clusters of farmers devoting different fractions of their land to subsistence and market cro…
Community Water Governance on Mount Kenya
Kenyan river basin governance underwent a pioneering reform in the Water Act of 2002, which established new community water-management institutions. This article focuses on community water projects in the Likii Water Resource Users Association in the Upper Ewaso Ng’iro River basin on Mount Kenya, and the extent to which their features are consistent with Ostrom’s design principles of natural resource management. Although the projects have develop…
Regimes of Information
Socio-ecological systems are inherently complex. One source of complexity is the uncertainties involved in the decisions and behaviors of human actors that determine how landholdings are managed. Land management decisions are often influenced by diverse factors and considerations. Particularly significant among these are (1) the sources of information land managers utilize with their perceived quality, reliability, and accessibility; (2) the soci…
Assessing the transition from deforestation to forest regrowth with an agent-based model of land cover change for south-central Indiana (USA)
Geographic information systems, spatial network analysis, and contraceptive choice
How does family planning accessibility affect contraceptive choice? In this paper we use techniques of spatial analysis to develop measures of family planning accessibility, and evaluate the effects of these geographically derived measures in a multilevel statistical model of temporary method choice in Nang Rong, Thailand. In our analyses we combine spatial data obtained from maps and Global Positioning System (GPS) readings with sociodemographic…
