Four different files with land requirements (demand) scenarios have been created for the
period from 1997 to 2011. The land requirements are not very realistic for this short time
period, but allow us to clearly analyse the differences between the scenarios. Figure 7
summarizes the land requirements defined in the four scenarios:
1. Slow growth scenario, in this scenario a continuation of the land transformation
rates of the past ten years is assumed, meaning deforestation and an increase in the
area of coconut plantations, grassland and rice-area (file Demand.in1)
2. Fast growth scenario, in this scenario a higher rate of land transformation is
assumed, leading to rapid conversions of forest to coconut, grassland and rice fields (file
Demand.in2).
3. Food-focus scenario, a high rate of land transformation is foreseen, however,
compared to the 'fast growth scenario' relatively more land is dedicated to rice cultivation
in order to supply food for the population of the island (file Demand.in3).
4. Export oriented scenario, the same high land conversion rate applies. However, it is
assumed that high copra prices make it profitable to dedicate most land to coconut
plantations and less land to food crops (file Demand.in4)
