Impact of Landscape Level Land Use Changes with Study Sites in Nicaragua
     

 Background

The main cause of loss of natural resources in Central America is the advance of the agricultural border (UICN, 2001), demanding more land area to produce the same amount of food, as a consequence of the loss of the productive capacity of the ground and the decrease sources (García 2003), the traditional farming practices as crop in the zones of greater slopes, exaggerated use of agrochemical substances and overpasturing have caused negative impacts on the ecosystems (Córdoba, 2002).

At the moment livestock is one of the activities of production that have the biggest share of the regions economy (ILRI, 2004), although at the same time it has been announced one of the main causes of the natural ecosystems transformation, provocing the loss of the agrosystems sustainability (Kaimowitz 1996). Taking into account that the systems of extensive production are coming along with the degradation of natural ressources that exist in the forest, an approach of new technics, that are compatible with livestock production and the conservation of natural ressources become necessary. One of these approaches is the introduction of Silvopastoral technologies (Ibrahim et al. 1999).

SilvoPastoral Systems (SPS) constitute an alternative for cattle production, where wooded perennial (trees and/or shrubs) interact with the traditional components (herbaceous covers and animals) under a system of integral handling (Ibrahim, 1996). This is a system of sustainable production that, through transformations that improve the performance in production, generates environmental services when protecting and conserving the sources (Ibrahim et al. 2003).


 Objectives
  1. Identify land use of SPS by analysing satellite imagery (Lansat TM/ ETM+ and Quickbird).
  2. Identify the contribution of SPS to the recovery of forestal coverage and the cabon stock in Nicaragua by the application of GIS (Geographic Informatic Systems).
  3. Determine the duration of the carbon fixation in SPS.

 Working Plan
04/08 – 12/08: Detailed revision of the research plan proposal (bibliography and methodology)
01/09 – 07/08: Database revision of 5 years` monitoring of land utilisation (studying appropiate technologies recovering degraded areas in the tropics)
08/09 – 12/09: Processing of satellite imagery, GIS analysis
01/10 – 07/10: Final paper preparation
08/10 – 10/10: Final revision and presentation
