We can increase the removal of carbon dioxide from the atmosphere by growing more forests. This can be done by:

• establishingforestsonlandthathasnotbeena forestforaverylongtime(severaldecadesago)-this iscalledafforestation;

• re-establishingforestsinanareathatwasrecentlya forest(aroundadecadeago)-thisiscalled reforestation;

• plantingsuitabletreesindegradedforestareasto restoreforeststructure.

Theseactivitieswillincrease carbon sinksandpromotethe establishment of valuable forest ecosystem services.

We can reduce the amount of carbon dioxide released into the atmospherebyreducingtheareasofforestremovedandtreescutdown.Thiscanbedoneby:

• preventingtheconversionofforeststoanotherland usetype(e.g.properlanduseplanningofforestareas tominimiseforestclearanceinsteadofcompletely clearingtheforesttoestablishcashcropplantations orpastureland);

• applyinglessdestructivetimberharvestingtechniques (e.g.selectonlysuitabletreestoharvestandensure minimumenvironmentaldisturbancewhenputtingin loggingroadsandtracks);

• practisingfarmingsystemsthatminimisetheremoval oftrees(e.g.applyagroforestryfarmingsystems);

• conservingforeststhatareunderthreatofbeing removed.

Theseactivitieswillprotect carbon pools and sinks and maintain forest ecosystem services.
