ASSESSING SPATIAL BREAK-EVEN VARIABILITY IN FIELDS WITH TWO OR MORE MANAGEMENT ZONES [PDF]

Farmers are interested in knowing whether applying inputs at variable rates across a field is economically viable. The answer depends on the crop, the input, their prices, the cost of variable rate technology (VRT) versus uninform rate technology (URT ...

Scholarly collaboration across time zones [PDF]

, 2008
The barriers to global collaboration of yesteryear were, for example, country boundaries and time zones. Today however, in a world where communication is thriving on new technologies, these barriers have been overcome, not only by the technology itself ...

Management zone delineation using a modified watershed algorithm [PDF]

Le zonage intra-parcellaire est une méthode couramment utilisée pour gérer la variabilité intra-parcellaire. Ce concept consiste à partitionner une parcelle en zones de management selon une ou plusieurs caractéristiques du sol et/ou du couvert végétal de

Coastal zone management

Land Use Policy, 1991
Bangladesh, St Lucia, the Philippines and dozens of other countries are affected by serious storms and flooding. The damage from these and other hazards could be reduced through effective programmes that control the type, density and location of coastal settlements.

How tightly linked are Pericopsis elata (Fabaceae) patches to anthropogenic disturbances in Southeastern Cameroon? [PDF]

, 2015
While most past studies have emphasized the relationships between specific forest stands and edaphic factors, recent observations in Central African moist forests suggested that an increase of slash-and-burn agriculture since 3000–2000 BP (Before Present)
