Coupled Natural-Human Systems
Resolving social-environmental system dynamics in subsistence agriculture and developing sustainable water management strategies
Coupled Natural-Human Systems Research
Our CNH research examines the complex interactions between human activities and natural systems, with a focus on agricultural sustainability, food security, and livelihood resilience. We investigate how social and environmental factors interact to shape outcomes for people and ecosystems in dryland regions.
Research Focus
Dryland regions support over 2 billion people, many of whom depend on rain-fed agriculture for their livelihoods. These systems face increasing pressures from climate change, population growth, and economic transformation.
Our research helps understand how human and natural systems interact and co-evolve, informing strategies for sustainable development and climate adaptation in vulnerable regions.
Methodological Approach
We combine household surveys, participatory methods, and quantitative analysis with biophysical measurements and remote sensing data. Our work integrates social science methods with natural science approaches.
Field sites include smallholder farming systems in Kenya, Zambia, and Ghana, providing insights into diverse agricultural and livelihood contexts across sub-Saharan Africa.
Key Research Areas
Our CNH research spans multiple interconnected areas of investigation
Agricultural Adaptation
How farmers adapt their practices to climate variability and change, including crop selection, planting dates, water management, and risk mitigation strategies.
Water Resources Management
Sustainable management of water resources in smallholder systems, including irrigation efficiency, groundwater use, and community-based water management institutions.
Food Security
Drivers of food security and nutrition outcomes in dryland regions, including crop productivity, market access, dietary diversity, and seasonal food availability.
Livelihood Sustainability
Resilience and sustainability of rural livelihoods, including income diversification, social networks, and adaptive capacity in the face of environmental and economic shocks.
Land Use Change
Drivers and consequences of land use and land cover change, including agricultural expansion, deforestation, and the impacts on ecosystem services and biodiversity.
Climate Risk Perception
How farmers perceive and respond to climate risks, including cognitive biases, traditional knowledge systems, and the role of information in decision-making.
Research Locations
Our CNH research is conducted across multiple sites in sub-Saharan Africa
Kenya
Smallholder farming systems in semi-arid regions, focusing on maize-based agriculture and pastoralism interactions at the Mpala Research Centre.
Zambia
Climate adaptation and food security in the Southern Province, examining how farmers respond to rainfall variability and seasonal forecasts.
Ghana
Urban food security and peri-urban agriculture, investigating the connections between rural production and urban consumption systems.
