With the increasing role of NFFs, their structures and operational procedures are becoming more complex and diversified. While many of these funds are State-driven and often support projects that include public goods with a focus on social and environmental benefits, some also support privately managed small-scale “for profit” businesses related to wood and non-wood forest-based value chains. This paper describes some the recent developments of NFFs and presents the results of a research effort that analyzed how NFFs’ funding targeting small-scale forest enterprises can contribute to the provision of forest ecosystem services. For this analysis, five case studies from Costa Rica, Guatemala, Luxembourg, Portugal, and Tanzania have been selected. In specific, the Forest Financing Fund (FONAFIFO), the FONABOSQUE, the Forest and Climate Change Fund (FCCF) of Luxembourg, the Floresta Atlantica Fund, and the Tanzania Forest Fund (TaFF) are reviewed. The research addressed several key research questions, including: How are NFFs operations conceived to support small-scale forest businesses? What type of funding windows are targeting small-scale enterprises? What are the current practices of NFFs supporting ES provision through small-scale forest businesses? How could NFFs further support small-scale enterprises while unleashing contributions to the provision of ES?

Leaf Area Index measurements in a tropical moist forest: a case study from Costa Rica / M. Kalacska in Remote sensing of environment, vol 91 n° 2 (30/05/2004)

Therefore, there is a greater need for accurate and detailed information about their biophysical characteristics (e.g., Leaf area index-LAI) along different stages of ecological succession. Remote sensing offers the possibility of providing relatively accurate estimations of such biophysical characteristics at a reasonable cost for most regional projects. The objectives of this study are to (1) document the variability of LAI in different stages of secondary growth in a tropical moist forest, (2) estimate LAI from spectral vegetation indices (SVIs), and (3) link LAI to the estimation of other canopy physiognomic characteristics. We found that segregation of LAI measurements by successional stage (early, intermediate, late) contributed to a better definition of the relationship between LAI and the SVIs. In addition, we conclude that the propagation of errors of precision through the SVI formulas must be taken into consideration along with intra-site and radiometric variability when uncertainty terms are calculated. From a linear regression analysis, we found that there is only a minimal difference between the nonparametric Theil-Sen and classical least-squares regressions. We also found that not only does the Lorentzian cumulative transition function describe the relationship between LAI and the SVIs, it also provides an estimate of the range of LAI values to which each index is sensitive.

Statistical methods to partition effects of quantity and location during comparison of categorical maps at multiple resolutions / Robert Gilmore Pontius in Photogrammetric Engineering & Remote Sensing, PERS, vol 68 n° 10 (October 2002)

This methodology quantifies agreement between any two categorical maps, where either map uses fuzzy or crisp classification. The method measures the agreement at various resolutions by aggregating neighboring cells into an increasingly coarse grid. At each resolution, the method partitions the overall agreement into correct due to chance, correct due to quantity, correct due to location, error due to location, and error due to quantity. In addition, the method computes six statistics that are useful to interpret the differences between maps, and shows how these statistics change with resolution. This technique is particularly useful for characterizing land-cover change and for validating landcover change models. For illustration, this paper applies these theoretical concepts to the validation of a land-use change model for Costa Rica.

Flight lines were repeated with a 15 to 30 minute time difference for measurement of forest canopy thermal response over time. Concurrent radiosonde measurements of atmospheric profiles of air temperature and moisture provided inputs to LOWTRAN6 for atmospheric radiance corrections of the TIMS data. Techniques for using calibrated aircraft-based thermal scanner data to examine tropical forest canopy thermal properties are described. Forest canopy temperature changes over time assessed between repeated, duplicated flight lines were combined with estimates of surface radiative energy measurements from towers above the forest canopy to determine temperature spatial variability, calculate Thermal Response Numbers (TRN), and estimate evapotranspiration along the elevation gradient from selected one hectare forest inventory plots.
