    Changing dietary preferences and population growth in South Asia have resulted in increasing demand for wheat and maize, along side high and sustained demand for rice. In the highly productive northwestern Indo-Gangetic Plains of South Asia, farmers utilize groundwater irrigation to assure that at least two of these crops are sequenced on the same field within the same year. Such double cropping has had a significant and positive influence on regional agricultural productivity. But in the risk-prone and food insecure lower Eastern Indo-Gangetic Plains (EIGP), cropping is less intensive.

    The standard System of National Accounts (SNA) omits the costs of the environmental inputs from nature and the environmental fixed asset degradation from the national/sub-national natural working landscapes. The United Nations Statistic Division (UNSD) is currently drafting the standardization of the Experimental Ecosystem Accounting (EEA), as part of the System of Environmental-Economic Accounting (SEEA).

    Intercropping, i.e. the cultivation of crop species mixtures, can potentially reduce pressure on land resources by generating higher yields through exploitation of complementarities between crop species. Although intercropping is practiced on a non-negligible proportion of China’s arable land, little is known about the factors that influence farmers’ decisions to use intercropping. In this study we develop a theoretical framework that distinguishes exogenous factors from endogenous factors in farmers’ activity choices in general and the use of intercropping in particular.

    Action-based payments that compensate farmers for adopting land-management measures to preserve and enhance the environment have been criticized for being ineffective. The root of the problem is that farmers are not paid for achieving a desired environmental benefit, but compensated for their costs of management. There is growing interest in formulating result-based economic incentives.

    Despite its ostensible future orientation, research on land use planning has given relatively little consideration to temporality, either empirically or conceptually. The need for analytical advances becomes clear when considering the treatment of ‘end-of-life’ issues for renewable energy facilities like onshore wind. Expanding renewables is central to sustainable energy futures yet land use regulation often treats consents as ‘temporary’, raising questions about how the trajectories of energy transition are maintained into the future.

    Policy makers concerned with the peri-urban interface find their greatest challenges in the rapid urban growth of developing mountain regions, since limitations caused by relief and altitude often lead to an increased competition between rural and urban land use at the valley floors. In this context, little attention has been paid to the affected agriculturalists’ perceptions of peri-urban growth—important information required for the realization of sustainable land use planning. How is the process of rural–urban land change perceived and assessed by peri-urban smallholder communities?

    Within the debate about rural development policy (RDP), there has been increasing call for a stronger territorial focus emphasising the potentials, resources and demands of regions. Investments in territorial capital and regional capacity building have been considered as the two main cornerstones of a place-based approach to rural development (OECD, 2006). On the basis of an analytical literature review, we developed a framework to operationalise a place-based approach of RDP.

    Climate change is a major driver of land use with implications for the quality and quantity of water resources. We apply a novel integrated impact modelling framework (IIMF) to analyze climate change impacts until 2040 and stakeholder driven scenarios on water protection policies for sustainable management of land and water resources in Austria. The IIMF mainly consists of the sequentially linked bio-physical process model EPIC, the regional land use optimization model PASMA[grid], the quantitative precipitation/runoff TUWmodel, and the nutrient emission model MONERIS.

    We assess the production impacts of a 100% conversion to organic agriculture in England and Wales using a large-scale linear programming model. The model includes a range of typical farm structures, scaled up across the available land area, with the objective of maximising food production. The effects of soil and rainfall, nitrogen (N) supply/offtake and livestock feed demand are accounted for. Results reveal major reductions in wheat and barley production, whilst the production of minor cereals such as oats and rye increase.

    Slower than desired growth in crop yields coupled with rising food demand present ongoing challenges for food security in Africa. Some countries, such as Tanzania, have signed the Malabo and Abuja Declarations, which aim to boost food security through increasing crop productivity. The more intensive use of seed and fertilizer presents one approach to raising crop productivity. Our simulation study examined the productivity and economic effects of planting different seed cultivars and increasing fertilizer application rates at multiple spatial scales for maize in Tanzania.
