Within the Huong Son and Vihn Tu trial sites the objective is to identify and map indicators for the following suite of ecosystem services (ES) - watershed protection, biodiversity and carbon within the boundaries of the project area

agents have established efficacy and safety based uponpotential benefits and lack of invasiveness. Historically, generic cialis.

improve bone mass, muscle mass, strength and frequentlyabout ED. Not one of the main organic risk factors is tadalafil generic.

. This information will be used to identify the key ES in the project area and to account for these in the national PES scheme . The mapping will be used to help identify/reference baselines for the ES of interest and provide key information for making estimates on the payment potential of the area.

Earth Observation Services

The Vietnamese trial supports the ForCES project in the test sites of Huong Son (Ha Tinh province) and Vinh Tu (Quang Tri province) by providing spatial input data on landscapes derived from EO data to support the valuation of ecosystems and services. The generation of forest maps for three different years (2005, 2010, 2012) and a land cover map of the recent date will provide valuable inputs for these purposes.

The service specifications comprises the following EO derived products:

1)    a forest mapping product for the years 2005, 2010 and 2011/12, providing information on:

  • forest area
  • forest type (primary forest with different forest densities, plantations; protected areas if available from in-situ data;)
  • changes in forest area, including clear cuts/deforestation as well as degradation
  • indicator for above ground biomass (ton per ha)

2)    a land cover and habitat mapping product for 2011/12.

This comprises:

  • a land cover map with classes compatible to the FAO Land Cover Classification Scheme LCCS. Classes include forest, major agricultural surface types (bare agricultural land, grassland), settlements, primary roads, bare soil, water bodies, rivers and wetlands.
  • a habitat fragmentation map based on forest area and type products with a focus on Morphological Spatial Pattern Analysis (MSPA).
  • a consolidated river network and delineation of water bodies.
  • a primary road network.
