Monitoring vegetation dynamics and carbon stock density in miombo woodlands
BACKGROUND The United Nation's Program for Reducing Emissions from Deforestation and Forest Degradation (REDD+) aims to reduce the 20% contribution to global emissions of greenhouse gases from the forest sector, offering a financial value of the carbon stored in forests as an incentive for local communities. The pre-requisite for the setup of a participatory REDD + Program is the monitoring, re...
متن کاملQuantifying the sampling error in tree census measurements by volunteers and its effect on carbon stock estimates.
A typical way to quantify aboveground carbon in forests is to measure tree diameters and use species-specific allometric equations to estimate biomass and carbon stocks. Using "citizen scientists" to collect data that are usually time-consuming and labor-intensive can play a valuable role in ecological research. However, data validation, such as establishing the sampling error in volunteer meas...
متن کاملStock prices and house prices: Which one affects the other?
Stocks and houses as two major assets which play important role in the balance sheet of Iranian households. Changes in two markets have a large influence on wealth and the general economy. The purpose of this study is to examine the relationship between stock and house prices over a thirty-year period using vector auto-regression (VAR). Using yearly data for the period from 1985 to 2013, we con...
متن کاملEffect of Sampling Density on Estimation of Regional Soil Organic Carbon Stock for Rural Soils in Taiwan
Accurately quantifying soil organic carbon (SOC) stocks in soils is considered necessary and important for studying the soil quality and productivity, modeling the global carbon cycle, and assessing the global climate change. The objectives of this chapter are (1) to evaluate the effects of sampling density and interpolation methods on spatial distribution of SOC density (SOCD) and (2) to estim...
متن کاملHydraulic redistribution of soil water by roots affects whole-stand evapotranspiration and net ecosystem carbon exchange.
*Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation. *By measuring soil water content, sap flow and eddy covariance, we investigated the temporal variability of HR in a loblolly pine (Pinus taeda) plantation during months of normal and below-normal precipitation, and ...
