**REDD Abacus SP** is a public domain software developed by the [World Agroforestry Centre (ICRAF)](http://www.worldagroforestry.org/sea) to:
* Estimate emission from land use and land cover changes allowing for dynamic heterogeneity of soil types, elevations, climate and other biophysical characteristics in the landscapes
* Analyze trade-offs between emissions and financial gain (opportunity cost analysis) and produce abatement cost curves Project ex-ante emissions and financial gain of business-as-usual scenarios for setting Reference Emission Level (REL)
* Simulate zone-specific policies and other emission reduction scenarios within the landscapes, and estimate the potential emission reductions and opportunity costs of them
**REDD Abacus SP** can serve as a main tool in:
* Developing land use plan for low emission development strategies at the province or district level
* Assessing carbon efficiency of a large scale land-based enterprise
* Estimating abatement cost o
Today’s small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!
