Many agent-based systems rely for their effectiveness on the intelligence of individual agents, and interaction among agents is required simply to coordinate these individually complex decisions. Specification and design methods for such systems focus on the internal architecture of individual agents. An alternative approach, “Synthetic Ecosystems,” uses relatively simple agents and draws heavi...
An appreciation of the dynamism of the links between soil resources and society provides a platform for examining food security over the next 50 years. Interventions to reverse declining trends in food security must recognize the variable resilience and sensitivity of major tropical soil types. In most agro-ecosystems, declining crop yield is exponentially related to loss of soil quality. For t...
Heavy metals including cadmium (Cd) and lead (Pb) are entering agricultural soils from different routes and mainly due to human activities. Accumulated Cd and Pb in the soil would eventually enter the human and animal food chains and pose threat to their health. Therefore, evaluating heavy metal accumulation is necessary to prevent soil and environmental pollutions and should be considered by r...
Agricultural expansion is a major driver for loss of biodiversity; changes in land use or intensity associated with trade liberalisation can therefore have major consequences. Assessments of the impacts of agricultural trade have tended to neglect biodiversity, despite its crucial role in maintaining productive agro-ecosystems. Advice on assessment of biodiversity impacts is required to support...

Renewable Agriculture and Food Systems is a multidisciplinary journal which focuses on the science that underpins economically environmentally and socially sustainable approaches to agriculture and food production. The journal publishes original research and review articles on the economic, ecological and environmental impacts of agriculture; the effective use of renewable resources and biodive...
Introduction Achieving more sustainable consumption and production in the agricultural sector requires a coherent response to the intimate linkages between agricultural production, agro-ecosystems and the people who rely on them, and also the concerns and preferences of a growing number of consumers. Less input intensive and more resource efficient agriculture offers a means to strengthen the c...
This article explores the implications for human health of local interactions between disease, ecosystems and livelihoods. Five interdisciplinary case studies addressed zoonotic diseases in African settings: Rift Valley fever (RVF) in Kenya, human African trypanosomiasis in Zambia and Zimbabwe, Lassa fever in Sierra Leone and henipaviruses in Ghana. Each explored how ecological changes and huma...
