This theme looks at freshwater, food and ecosystem services in dynamic social-ecological landscapes
Water is the bloodstream of the biosphere that makes agricultural activities possible. Agricultural land use now covers large parts of the terrestrial planetary surface. While producing food for a growing world population, it also pushes against many of the planetary boundaries and thus impairing social-ecological resilience.
This theme works on a range of scales, from local landscapes to analysis of global freshwater and agricultural changes, and cross-scale teleconnections. It focuses particularly on operationalising resilience in relation to the water-food-poverty nexus in semi-arid to dry sub-humid parts of the world. Theme members have substantial fieldwork in e.g. the West African Sahel, India, Tanzania and South Africa.
The theme also looks at relationships among multiple ecosystem services and how these can generate synergies or trade-offs between e.g. food production, carbon sequestration, and water availability.

Extreme rainfall variability has been one of the major factors to famine and environmental degradation in Ethiopia. The potential for water harvesting in the Upper Blue Nile Basin was assessed using two GIS-based Multicriteria Evaluation methods: (1) a Boolean approach to locate suitable areas for in situ and ex situ systems and (2) a weighted overlay analysis to classify suitable areas into different water harvesting suitability levels. The sensitivity of the results was analyzed to the influence given to different constraining factors. A large part of the basin was suitable for water harvesting: the Boolean analysis showed that 36% of the basin was suitable for in situ and ex situ systems, while the weighted overlay analysis showed that 6–24% of the basin was highly suitable. Rainfall has the highest influence on suitability for water harvesting. Implementing water harvesting in nonagricultural land use types may further increase the benefit. Assessing water harvesting suitability at the larger catchment scale lays the foundation for modeling of water harvesting at mesoscale, which enables analysis of the potential and implications of upscaling of water harvesting practices for building resilience against climatic shocks. A complete water harvesting suitability study requires socioeconomic analysis and stakeholder consultation.

Denna rapport är framtagen som del av ett forskningsprojekt som undersöke huruvida metoden resiliensanalys, ”Resilience Assessment”, är användbar och til hjälp inom kommunal förvaltning. Det är ett led i metodutveckling av resiliensanalysen. Resultaten avseende livsmedelsförsörjningen i Eskilstun kommun är vad som framkommit under processen och har inte varit själv forskningsfrågan. Eskilstuna kommuns arbete har letts av Lars Wiklund och Lars-Erik Dahlin. Från Stockholm Resilience Centre och Albaeco har arbetet letts av My Sellberg och Louise Hård af Segerstad.

Zoonotic diseases are the main contributor to emerging infectious diseases (EIDs) and present a major threat to global public health. Bushmeat is an important source of protein and income for many African people, but bushmeat-related activities have been linked to numerous EID outbreaks, such as Ebola, HIV, and SARS. Importantly, increasing demand and commercialization of bushmeat is exposing more people to pathogens and facilitating the geographic spread of diseases. To date, these linkages have not been systematically assessed. Here we review the literature on bushmeat and EIDs for sub-Saharan Africa, summarizing pathogens (viruses, fungi, bacteria, helminths, protozoan, and prions) by bushmeat taxonomic group to provide for the first time a comprehensive overview of the current state of knowledge concerning zoonotic disease transmission from bushmeat into humans. We conclude by drawing lessons that we believe are applicable to other developing and developed regions and highlight areas requiring further research to mitigate disease risk.

Many production landscapes around the world have been sustained through appropriate use and management of natural resources, but many are now facing overuse or underuse. This paper explores future perspectives on the satoyama landscape (traditional Japanese rural landscape) as a social–ecological system through an overview of its transformation. Two phases in the human–nature relationship are observed: before the fossil fuel revolution of the late 1950s, people maintained a direct relationship with nature, and the landscape was integrally managed through community cooperation to avoid overuse; then, after the late 1950s, inflow of goods and services from outside and outflow of the population resulted in underuse of natural resources, and the human–nature relationship became weakened and more indirect. Rebuilding the human–nature relationship in the present day calls for efforts that go beyond the local level toward cross-scale, connected and coupled social–ecological systems.
