The phrase "afforestation activities" is correct and usable in written English.
It can be used when discussing efforts or initiatives aimed at planting trees and restoring forested areas.
Example: "The government has launched several afforestation activities to combat climate change and promote biodiversity."
Alternatives: "tree planting initiatives" or "forest restoration efforts".
Particularly notable are consistent intensification of agricultural and, afforestation activities in the inner sectors of the dunes and a widespread urbanization.
Erica arborea utilisation has declined dramatically during the past century, mostly due to the decreasing demand for smoking pipes, as well as the increasing frequency of wildfires and large-scale afforestation activities in this region.
In the past, monoculture tree plantation was the primary method used in afforestation activities in central Yunnan; in recent years however, several different methods of restoration have been introduced including the use of agroforestry systems.
Likewise, afforestation activities have recently also been questioned in the context of possible additional methane emissions from trees – the second-most important greenhouse gas [44].
At the same time, net emissions from grassland in 2030 is expected to be increased by 1 Mt CO2e year−1 (compared to 2007 levels) mainly relating to afforestation activities reducing the total area of grassland.
In the case of Australia and New Zealand, this includes a lack of inclusion of harvested wood products in applicable methods and recognised afforestation activities and in Australia a relatively short contract period for the purchase of emission reductions by the Australian Government.
Furthermore, nonmetric multidimensional scaling analysis showed that the influence degree of afforestation on activities of the four enzymes was higher than that of temporal variation.
The principle of conservativeness has already been reflected in several UNFCCC documents, for example in the context of afforestation and reforestation activities under the Clean Development Mechanism (CDM) [19, 20].
With this scheme a country may report on changes in carbon stock due to land use change activities (afforestation, reforestation and deforestation) reporting differences in carbon stock between forest land and cropland, grassland, wetland, settlement and other land.
In this consideration, the evaluation of specific site conditions referring to the plant-effective water deficiency and the plant-internal, physiological ability of adaptation towards these, are recommended as key-parameters, for, e.g., afforestation and reforestation activities in arid lands, or as an approach for bio-monitoring of declining vegetation types in arid zones.
