Synopsis (short abstract) Melia dubia Cav., member of family Meliaceae, found upto 1800 amsl in India and thrives well under variety of soils and climatic conditions. The short rotation indigenous tree meets raw material requirements of timber, veneer, ply and paper industries. Forest Research Institute, Dehradun, India has released ten cultivars for commercial cultivation with excellent bole form and average productivity of 34.57 m3ha-1 yr-1. These varieties are not only potentially contributing in supply of raw materials to different industries but also pivotally reducing foreign exchange. Though evaluated germplasm consisted exceptional variability for pulping parameters, few genotypes were found utmost suitable for paper manufacturing with pulp yield upto 55.32 %.The general purpose plywood (interior grade) was found to meet IS specification, and Progeny No. FRI/MD/104 performed with maximum modulus of rupture and modulus of elasticity along and across the grains, followed by Progeny No. FRI/MD/028, FRI/MD/075 and FRI/MD/076. Additionally, ply made from wood of Progeny No. FRI/MD/028 and FRI/MD/076 performed suitably in dry and wet state glue shear strength. The ply manufactured from this wood fetches handsome price in the market with low maintenance expenditure. Economically, plantations of the species are most suited to growers and when planted in rows along the field bunds about 60 trees can be planted per acre generating an income of about Rs. 2 Lakh in sixth year of planting. On the other hand, planting 300 to 400 trees per acre in blocks give a minimum profit of Rs. 1 lakh per year from an acre. Under good maintenance and controlled irrigation from sixth year onwards, trees with about 100 cm GBH and clear bole of 5 to 7 meters can fetch upto Rs. 4000 to Rs. 5000 per tree depending on soil depth and quality. Furthermore, total carbon stock and CO2 sequestration potential of improved varieties calculated substantially higher to the tune of 17.90 and 82.80 t.ha-1 yr-1.

The preservation of natural forests through the establishment of industrial wood production plantations via the new, fast growing Robinia pseudoacacia ‘Turbo Obelisk’ varieties and new cultivation technologies

After decades of research and development, Silvanus Forestry Ltd. and HungaroPlant Ltd. have successfully propagated the Robinia pseudoacacia ‘Turbo Obelisk’ variety group and developed the necessary cultivation technologies, specifically for intensive industrial wood production plantations. In comparison to the Hungarian and traditional black locust varieties and cultivation technology, industrial wood production plantations established with our variety group and using our cultivation technologies can produce twice as much timber yield and industrial timber yield, considering 15-year rotation periods. These parameters are comparable with the performance of the widespread Eucalyptus and Pinus plantations in the subtropics. Our varieties and cultivation technologies, however, are also usable in subtropical, temperate, as well as tropical climates. The outstanding yields achieved by the ‘Turbo Obelisk’ varieties and the extremely high industrial wood output can provide a significant contribution to the conservation and maintenance of natural ecosystems, whilst the CO2 sequestration per unit area per time is also several times that of natural forests. A particular advantage to emphasize is long term carbon sequestration due to the high percentage of industrial wood yield. Increasing the exceptional tolerance of black locust against drought, pollution and low-quality soils, our varieties are exceptionally suitable for the utilization of marginal agricultural areas, the agricultural utilization of which would otherwise create an economical loss. This can also significantly increase the advancement of less developed regions. In addition to plantation cultivation, it also provides a cost-effective solution for the establishment of protective forest belts, road-side plantings, quicksand fixation and soil renovation. Delicious honey production is also a possible revenue stream. The global exploitation of the research findings has begun, having already successfully established test plantations in China, India, and Pakistan, as well as in several European countries.

Forests and trees supporting rural livelihoods 2017

In Myanmar and Vietnam the political framework is conducive to support the allocation of forests to farm communities and private households, to facilitate community and farm forestry and to support the establishment of community forestry user groups and enterprises. The main crops planted in both countries are rice and maize. In Myanmar most crops are used for subsistence purposes, in particular in Chin State. In Vietnam about two thirds of the planted crops are sold in the market. In the provi nces included in the survey the agricultural area available for each person in Myanmar was found to be four times larger than in Vietnam, while the forest area per person was four times smaller. Accordingly, the results of the survey suggest that, in Myanmar, more than half of the peoples’ income originates from agriculture, whereas forestry supplies only 8% of the total family income. Forests and trees have a higher significance for rural livelihoods in Vietnam, where the bigger part of the fam ily income originates from forestry while agriculture only supplies less than one third. In Myanmar rural communities plant trees on both the communal and individually owned forest land. The most preferred species for planting are hardwoods, namely Teak (Tectona grandis) and Pyinkado (Xylia xylocarpa), as well as some eucalypts (Eucalyptus spp.). Some communities also plant other fast growing species (Gmelina, Acacia, Cassia). In Vietnam many communities possess individual land use rights for fo rests besides some communal woodlots. Farmers plant mainly fast-growing species (Acacia spp, Magnolia conifera, Bamboo, Melia azedarach, Chukrasia tabularis) and some trees that produce non-wood forest products (star anise, canarium nuts, cinnamon, styrax resin).
