Land use/cover change (LUCC) is often the cumulative result of individual farmer's decisions. To understand and simulate LUCC as the result of local decisions, multi-agent systems models (MAS) have become a popular technique. However, the definition of agents is not often based on real data, ignoring the inherent diversity of farmers and farm characteristics in rural landscapes. The aim of this paper is to describe an empirical method that defines an agent typology and allocates agents into the different agent types for an entire region.

The spatial and temporal dynamics in the stream water NO3-N concentrations in a major European river-system, the Garonne (62,700 km2), are described and related to variations in climate, land management, and effluent point-sources using multivariate statistics. Building on this, the Hydrologiska Byrans Vattenbalansavdelning (HBV) rainfall-runoff model and the Integrated Catchment Model of Nitrogen (INCA-N) are applied to simulate the observed flow and N dynamics.

Having done research on agricultural decollectivization and its consequences since 1992, Ilkka Alanen and his colleagues has accumulated a wealth of knowledge on the coping strategies people adopted in order to survive in the Baltic countries and elsewhere (See Alanen 1998, Alanen et al 2001 and Alanen 2004a). The problems turned out to be much more difficult than the reforms planers anticipated, and that some of the initial failures still overshadow people’s lives.

Based on a survey of woodland owners in West Virginia, we examined the possibility of differences in the characteristics of those who had and had not received information about local invasive plants and implications for outreach providers. Findings suggest that landowners who farmed on their property, held recreation objectives, and lived in the local area were significantly more likely than their counterparts to have received information. A majority of landowners with these characteristics, however, had not heard or read such information.

Agricultural development on floodplains contributes to hydrologic alteration and forest fragmentation, which may alter landscape-level processes. These changes may be related to shifts in the seed bank composition of floodplain wetlands. We examined the patterns of seed bank composition across a floodplain watershed by looking at the number of seeds germinating per m² by species in 60 farmed and intact forested wetlands along the Cache River watershed in Illinois.

The aim of this study was to evaluate accuracy of farmer's paternity identification which determines success of future breed selection and hence genetic gain. Paternity of 269 Orma/zebu and Sahiwal/zebu calves was evaluated using genetic markers and the likelihood based method. Results indicate that only 6.7% farmer alleged paternities were confirmed, 88% parent-offspring relationships were rejected and 18% parent-offspring relationships were undetermined. However, 82% of offsprings were assigned at least 80% confident paternities to one of the sampled candidate males.

This year's annual report in addition to the 2007 research work also covers key events in the first half of 2008, particularly matters pertaining to the continuing global food price crisis. There is a special section on the record-high food prices; and an introduction to ILRI's 'Improving Market Opportunities' Theme. This annual report comprises three chapters, viz., East Africa; South Asia; and Southern Africa.
