a r t i c l e i n f o We outline several diversity factors that modellers and models can include directly or indirectly in order to improve the accuracy and usefulness of the model. Without considering these factors, different types of diversity deficit can arise. These deficits can be considered in three domains: 1) in the real world where actual diversity(More)
Article history: Available online xxxx Keywords: Urban segregation Urban complexity Social simulation Agent-based model Brazil a b s t r a c t Urban segregation represents a significant barrier to achieving social inclusion in cities. To mitigate this problem, it is necessary to implement policies founded upon a better understanding of segregation dynamics.(More)
Keywords: Agent-based model Ecosystem services trade-offs Household decision making Payments for ecosystem services (PES) PES conditionality Land-use/cover change a b s t r a c t Rubber agroforests in the mostly deforested lowlands of Sumatra, Indonesia are threatened by conversion into monoculture rubber or oil palm plantations. We applied an agent-based(More)
This paper describes three fundamental pitfalls or caveats of empirical modeling of land-use decision making in agent-based models for land-use/cover change. A case study in the villages of Jambi Province (Sumatra), Indonesia, is presented to demonstrate the construction of empirical decision-making models using utility functions while taking into account(More)
Soil degradation by erosion is the most serious threat to food security in Ethiopia. Thus, effective management strategies (scenarios) that reduce soil degradation are crucial. However, the application of models such as Soil and Water Assessment Tool (SWAT) that simulate the impact of different scenarios on soil degradation by erosion in Ethiopia condition(More)
This study aims to identify and classify the geographic hotspots of human-induced land degradation in Vietnam. We used the long-term (1982–2006) trend of inter-annual NDVI, derived from AVHRR/NOAA imageries, as a proxy for the decline or improvement in biomass productivity on a national scale. By analyzing the temporal correlation between rainfall and NDVI(More)
This study has assessed the seasonal occurrence of annual vegetation fires and defined inter-seasonally burned area for the different vegetation cover types across Ghana and the northern region of Ghana using 10-year (2001–2010) remote sensing data. These values were used with fire induced elemental losses to estimate greenhouse gas emissions and net plant(More)
