The European forest carbon balance studied by various methods shows different results.
This study uses a combination of remote sensing data, field observations and information from local people to analyze the patterns and dynamics of land-use/cover changes for 35 years from 1972 to 2007 in the arid and semi-arid Northern Afar rangelands, Ethiopia. A pixel-based supervised image classification was used to map land-use/cover classes.
Dit onderzoek is in opdracht uitgevoerd voor mechanisatiebedrijf Basrijs in Rijsbergen en loonbedrijf Huijbregts in Zundert en is gefinancierd door het Ministerie van Economische Zaken met behulp van kennisvouchers van SenterNovem.
Global environmental changes observed during recent decades are likely to have had an impact on the distribution of species. Currently, silver fir (Abies alba) is becoming established in the subalpine forests of the west central Alps at elevations higher than 2000 ma.s.l.; prior to the 1970s its upper altitudinal limit was 2000 m.
Estimates of the percent of Earth's land surface that has either been transformed or degraded by human activity range between 39 and 50 percent, with agriculture accounting for the vast majority of these changes.
The Clean Development Mechanism (CDM), Article 12 of the Kyoto Protocol allows Afforestation and Reforestation (A/R) projects as mitigation activities to offset the CO2 in the atmosphere whilst simultaneously seeking to ensure sustainable development for the host country.
Background: The divergent glacial histories of southern and northern Europe affect present-day species diversity at coarse-grained scales in these two regions, but do these effects also penetrate to the more fine-grained scales of local communities?
The Indonesian economic quarterly reports on and synthesizes the past three months' key developments in Indonesia's economy. Its coverage ranges from the macro economy to financial markets to indicators of human welfare and development.
Onderzoekvoorstellen worden getoetst op wetenschappelijke kwaliteit én maatschappelijke kwaliteit door onafhankelijke deskundigen. De onderzoekprogramma’s hebben voor de Deltacommissie informatie aangedragen over de mogelijk te verwachten zeespiegelstijging.
