    Description: In this paper we present the generic modelling system SITE (SImulation of Terrestrial Environments), a software package to develop and apply models simulating regional land-use dynamics. The modelling system includes (i) a framework managing the model generics and (ii) code templates for the development of rule-based land-use and land-cover change (LUCC) models. SITE comprises built-in methods for e.g. map comparison, model optimization and environmental scenarios.

    Description: India's energy dependence on oil imports has led to energy security becoming a prime concern for policy makers and has thus warranted an exploration of alternative energy sources. Globally rising oil prices have led to greater interest in the development of bioenergy from plant based systems. This paper examines various policy options and mechanisms with respect to biofuel oilseed crops like Jatropha curcas and Pongamia pinnata, the potential of the expansion of sugarcane as a source of bioethanol and the emergence of the increased inclination towards afforestation of wastelands and associated implications and challenges. Historical land use data indicates that the agricultural area in India has stabilized over the last decades and has little opportunities of expansion. Considering India's still fast growing population, it is expected that land use conversions due to new bioenergy cropping systems are likely to intensify the already existing competition between residential/industrial land, and land required for food and energy generation. The paper reviews national and sub-national scale case studies, which are addressing a number of different topics related to bioenergy production, such as intensity of land use, crop yields, potential land demands or scenarios blending petrol with bioethanol.

    Description: After two decades of decreasing agricultural activities, in 2008 the Mongolian government started the “Third Campaign of Reclaiming Virgin Lands”, aiming at massive expansion and intensification of the agricultural sector. This policy motivated the study presented here, for which we used an integrated modelling approach to investigate the feedbacks between land-use dynamics, agricultural management and biophysical conditions, with a strong focus on assessing availability of water for irrigation. Our simulation results clearly show that under the current extend of irrigated agriculture in several years water demands exceeded water availability, indicating an overexploitation of water resources, mainly in the period 1995–2006. Consequently, the targeted expansion of agricultural water use will either severely deplete water resources with potential negative effects on other users and the environment, or policies are needed to mitigate or avoid potential adverse effects. As simultaneously Mongolian authorities struggle to implement integrated water resources management (IWRM), the latter might provide monitoring concepts and regulations needed to minimise the potential gap between water demands and availability. In this context, integrated modelling could be a scientific tool to support future land and water management decisions, as researchers already started to integrate views and demands of Mongolian authorities into scenario and model development (identified during stakeholder workshops), and will continue to do so during the coming years of collaborative research.

    Description: Biofuel initiatives in ndia have gained momentum with the national biofuel policy targeting 20% blending of both petrol and diesel by 2017. Most of ndia's biofuel plans revolve around using sugarcane for bioethanol and jatropha for biodiesel production. This study, taking the southern ndian state of arnataka as an example, aims at estimating the potential to achieve policy targets. The study spatially analyses land‐use change owing to biofuel expansion and its effects on food production. We used an integrated modelling framework to simulate land‐use change and bioenergy production under two scenarios – ndustrial conomy () and gricultural conomy (). Results indicate that meeting the 20% blending target is a challenging goal to achieve under both scenarios. Bioethanol requirements can be nearly fulfilled (88% under and 93% under ) because of sugarcane expansion. However, biodiesel demands cannot be fulfilled using only degraded lands as currently planned in India, but additional agricultural land (3–4% of the total cropland) will be required for jatropha‐based biodiesel production. Food production will not be directly impacted until 2025, because the largest source of additional land could be short‐ and long‐term fallows. We conclude that conservation oriented initiatives, such as water harvesting and energy conservation measures can increase productivities of biofuel crops and reduce fuel demands, respectively. State support and Clean Development Mechanism opportunities can enhance economic incentives for energy cropping. Therefore, a simultaneous and multipronged approach is needed to accommodate food and fuel demands in India.

    Description: In Northern Mongolia, water resources are stressed by an increasing water demand for water supply in households, agriculture and mining as well as by climate and land-use changes. This study aims to obtain a better understanding of the complex hydrological processes in the semiarid, subarctic Kharaa River Basin (KRB). Therefore, the water balance components and the characteristic patterns of the river hydrograph were systematically analyzed to identify the stream flow generating processes in the catchment. The distributed, physically-based Soil and Water Assessment Tool (SWAT) model was employed for simulation of stream flow under the particular hydrological conditions. During the period 1991–2002, roughly 87 % of precipitation ( P  = 216–417 mm/year) was lost due to evaporation, leaving only a small portion of water available for stream flow and groundwater recharge. The Kharaa’s hydrograph shows striking recurring patterns. River runoff in summer occurs as a response to strong summer rainfall events while stream flow generation in spring is almost exclusively driven by the melt of snow and river icings. This results in an inter-seasonal redistribution of water resources being effective for stream discharge in spring rather than in winter. Due to frozen soils, stream flow in spring is mainly generated by surface runoff and interflow. The thawing of the active layer during summer allows increased groundwater recharge. Stream flow during winter is reduced by continuously forming aufeis. Our results show that SWAT satisfactorily reflects stream flow for single years but is not reliable for a longer time period. Melt water from snow and icings could not be sufficiently simulated. The analysis reveals that refinements of SWAT are required, e.g. coupling a river ice model in order to deal with the subarctic situation in the KRB.
