DocumentDrones - A feasible way to revive forests
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The role of forests in human survival is inevitable but the forest cover decreases by deforestation increased wildfires and unpredictable climate change. To regrow forest we need a lot of manpower and as per some estimates a human can plant about 1500 trees a day and there are many inaccessible places like mountains, river beds, which is not easy for human planters to go, carry, and plant trees. To combat this we need to find out effective mechanisms to plant a large volume of tree seeds in a stipulated period over a mass area. The feasible solution for this is the usage of drones in reviving forests. Drones are unmanned aerial vehicles (UAV), they are like small helicopters which can be flown by a person standing on the ground using a remote.
Drones can fly and drop seeds at places that were difficult to reach earlier. They can map out the territory, carry the seeds, and drop the load at the identified spots, and go back to check the progress at frequent intervals and creating a large-scale green landscape. The built of the drone for planting trees are designed to be durable enough to lift the high quantity of seeds and they mark the areas suitable for dropping the seeds using machine learning technologies and 3D imaging. The seeds used in the drones are highly recommended to use a protected nutrient coating that acts as a safe shell to bury them in the ground, protect them from animals, and be flown away.
Forests still cover about 30 percent of the world’s land area, but they are disappearing at an alarming rate. About 17 percent of the Amazonian rainforest has been destroyed over the past 50 years, and losses recently have been on the rise. Given the ferocity of the devastation, we need hundreds of companies, individuals, and groups to come forward, leverage the technology, take these aerial vehicles to the sky and make the planet green again.

ArticleDegradation of the vegetation cover in the White Nile State (Elgetaina Area)
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The study was carried out in, White Nile State (East of Elgetaina town) during 2004- 2006. The selected site was dominated by Capparis decidua shrubs and Panicum tergidum grasses. The main objectives of the study were to investigate the limitation for natural regeneration of vegetation cover by studying the variation in rainfall amount and distribution, evaluating the soil properties and assessing the soil seed bank. The study aimed to suggest some measures to enhance the natural regeneration of the vegetation cover. The site was divided into four Blocks. Soil samples were taken from each Block, soil seed bank and soil chemical properties were determined. In addition, the vegetation density was estimated for each Block for trees, shrubs and grasses. Satellite imageries were used to monitor the change in the vegetation cover (Land uses and bare area maps). The results showed that the mean annual rainfall and distribution for the period 1987-2005, and soil seed bank has little effect on degradation of vegetation cover in the study area, and that the main cause of vegetation cover degradation is the deteriorated soil properties. The high sodicity/salinity reduced the seeds germination and the infiltration rate of the soil and most of rainfall is lost as runoff. Most of the study area is now bare (no vegetation). The study recommended use of water harvesting methods, soil reclamation with organic and inorganic materials and enrichment of soil seed bank for rehabilitation of the vegetation cover.

ArticleEffect of cutting dimensions, rooting media and incubation on vegetative propagation of Prunus armeniaca
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Propagation through cuttings of Prunus armeniaca – a tree borne oilseed of mid hills and dry temperate regions in India was tested by using three treatments. Vegetative propagation provides the opportunity in multiplication by cuttings by providing true-to-its-type plant and producing superior individuals. Effect of length and diameter, type and concentration of auxin and incubation method and duration on rooting of cuttings in wild apricot was studied. The study concluded that the optimal condition for rooting percentage in P. armeniaca is maximum using the incubator for 18 days on cutting length of 15 cm and cutting diameter of 1.0-1.5 cm after the application of IBA @ 5000 ppm. The survival percentage was also enhanced from 50.00 % to 53.33 % when cutting length of 15 cm and cutting diameter of 1.0-1.5 cm with IBA @ 5000 ppm incubated for 18 days at 30oC.
