Grasslands are an important land use in Europe with essential functions for feed and ecosystem service supply. Impact assessment modelling of European agriculture and the environment needs to consider grasslands and requires spatially explicit information on grassland distribution and productivity, which is not available. This paper presents and analyses spatially explicit data of grassland productivity and land use across regions in Europe. Data are extracted from various regional, national and international census statistics for Europe, extending eastwards to the Ural Mountains.
Exploring options for farm-level strategic and tactical decision-making in fruit production systems of South Patagonia, Argentina
In South Patagonia, Argentina, sweet cherry is the main fruit-tree crop grown for export, resulting in a highly seasonal labour demand. Managers of deciduous perennial fruit orchards must consider both biological and economic relationships in selecting crop species and orchard design. This makes decisions at the farm-level extremely complex, as especially in such perennial crops, strategic ('what to plant', 'with which technology' and 'how much area of each activity', i.e.
Transformation toward agricultural sustainability in New Zealand hill country pastoral landscapes
A multi-stakeholder representative group was established to oversee a project examining the economic and environmental performance of a representative North Island hill country catchment farm at Whatawhata in the western Waikato region of New Zealand. The group included representation from landowners, government agencies and scientists. The group was facilitated through an action research approach incorporating three phases: (1) awareness; (2) forecasting; and (3) implementation.
Landscape complexity and soil moisture variation in south Georgia, USA, for remote sensing applications
This research addressed the temporal and spatial variation of soil moisture (SM) in a heterogeneous landscape. The research objective was to investigate soil moisture variation in eight homogeneous 30 by 30m plots, similar to the pixel size of a Landsat Thematic Mapper (TM) or Enhanced Thematic Mapper plus (ETM+) image. The plots were adjacent to eight stations of an in situ soil moisture network operated by the United States Department of Agriculture-Agriculture Research Service USDA-ARS in Tifton, GA.
Challenges of optimal implementation of formal water rights systems for irrigation in the Great Ruaha River Catchment in Tanzania
In many countries around the world, increasing attention is being directed to the need to improve water rights systems. This paper is based on a recent study undertaken to investigate challenges facing optimal implementation of formal water rights systems for irrigation purposes in the Great Ruaha River Catchment in Tanzania. The study integrated social survey, hydrologic, water abstraction and water use data, and Geographical Information System techniques.
