Using a simulation model as an analysis tool, the economic impact of spittlebugs in pastures of Colombia was quantified in terms of animal production. Three levels of abundance (10, 25, 50 adults/m2 ) and farm area affected (25, 50, 100%) were evaluated using data obtained in Brazil for Notozulia...

The assessment of impact of climate change on coconut, a plantation crop, is challenging. However, the development of a simulation model (InfoCrop-COCONUT) has enabled the process. We present the first simulation analysis of the potential impacts of climate change on coconut productivity in India...

Long time series of daily meteorological data that are needed in various applications are not always available or appropriate for use at many locations. The Weather Generation Model (WGEN) developed by Richardson and Wright (1984) was evaluated as a substitute for daily observed data at 17 sites ...

This paper considers the mechanism of certification to encourage sustainable harvesting and best management practices of Iriartea deltoidea Ruiz and Pavon, in the context of current land use and agricultural management in Amazonian Ecuador. To understand the demographic variables that are critica...

Weighted goal programming (WGP) is employed to reconcile the goals of food security, improved incomes and woodland conservation in households from selected sites in Malawi, Mozambique and Zimbabwe. The three goals are attainable simultaneously, albeit with trade-offs useful in guiding development...

During the 1990s, a soils database was developed by the International Soil Reference and Information Centre in The Netherlands for the project “World Inventory of Soil Emission Potentials” (WISE). Using this database, we converted 1125 soil profiles from around the world into a format that can be...
