DocumentThe green pathway to growth and sustainability: Sustainable management of rubber plantations
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Vietnam Rubber Group (VRG) is the largest natural rubber producer, with over 410,000 ha located in Viet Nam, Laos, and Cambodia. VRG is always aware of the responsibility for a sustainable enterprise; VRG’s efforts demonstrate an excellent example in promoting rubber sustainability.
VRG is the leading enterprise in implementing the Viet Nam Forest Certification Scheme (VFCS) and PEFC certificates in the rubber sector. In 2021, about 55,000 ha rubber plantations and 22 natural rubber processing factories were certified under the VFCS/PEFC standards; another 57,000 ha and 14 natural rubber processing factories will be certified by the end of 2021 and 300,000 ha certified by 2022.
In economic terms, VRG rubber plantations have an average yield of 1.56 ton/ha/year, which is much higher than the global average yield, through the focusing on R&D and innovative solutions, especially: new high yielding rubber clones; advanced techniques in harvesting and soil protection; intercropping and Integrated Disease Management.
VRG pays attention to environmental values by applying the best practices to reduce significant carbon emissions: increasing the use of organic fertilizers; installing solar power systems for rubber factories; developing new processing process to reduce 40% of electric usage and DO oil; using biological waste treatment; and reusing 1.5 million m3/year (25% of total water usage) of treated wastewater.
VRG demonstrates the social responsibilities and has meaningful contributions to society by improving the living conditions of VRG workers and surrounding communities (infrastructure and health care facility improvement; job and income creation).
VRG strongly considers sustainable development as the green pathway of the future and business growth; VRG looks forward to sharing the best practices and the importance of industry sustainability leadership.

DocumentSucrose, photosynthetic photon flux density, & CO2 concentration affect growth & development of micropropagated mountain ash
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Mountain ash (Sorbus commixta Hedl.), is an important medicinal woody plant in Korea used for the treatment of cough, asthma, and other bronchial disorders. Unfortunately, the species is gradually disappearing due to over exploitation of the natural habitats. Tissue culture is a common and powerful technique for the clonal mass propagation which can be adapted to Mountain ash for ecosystem restoration. In an effort to establish a micropropagation method at the stage II for proliferation of shoots, Mountain ash was micropropagated under the so called a photo-autotrophic or photo-mixotrophic culture conditions. Micro-shoots of Mountain ash at the micropropagation stage II were cultured under two levels each of medium sucrose concentration (0 and 30 g.L-1), photosynthetic photon flux density (PPFD, 50 and 200 µmol.m-2.s-1), and CO2 concentration (350 and 1,000 µmol.mol-1). Axillary shoots originated from in vitro-grown plantlets, were stuck into and cultured on 50 ml per container of agar-solidified half-strength Murashige and Skoog (MS) medium with 2.0 mg.L-1 indole-3-butyric acid (IBA). Tissue water content, leaf length, and total chlorophyll content increased in plantlets cultured in the medium without sucrose (a photo-autotrophic condition). High PPFD promoted axillary shoot length, number of nodes, axillary shoot fresh weight, axillary shoot dry weight, leaf length, leaf width, and total chlorophyll content especially in the photo-autotrophic condition. High CO2 concentration increased axillary shoot length, number of axillary shoots, number of nodes, stem diameter, axillary shoot fresh weight, and axillary shoot dry weight. The treatment with a high PPFD, a high CO2 concentration, and without supplementation of sucrose to the medium (a photo-autotrophic condition) was better for growth and development in terms of number of nodes, tissue water content, leaf length, leaf width, and total chlorophyll content than those in the other treatments.

ArticleLand use and land use changes by the farmers from mulberry (Morus alba) plantations to green forest tree based farming for income growth and sustainability in Malda district of India
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Malda district was famous for two economic activities viz. Mango (Mangifera indica) cultivation and rearing mulberry silkworm (Bombyx mori). Earlier silkworm rearing was a flourishing cottage industry and every households of Kaliachak block reared silkworm for cocoon production. It was the major livelihood of rural farmers but they suffered heavily due to cheap import of silk from China. Thus, the backbone of farmers was crippled, hence they started cultivating various trees in mulberry fields along with agricultural crops for sustaining their livelihood. Present study was undertaken to know how farmers adjusted to new situation, their knowledge about trees, income growth and sustainability. It was observed that mulberry was raised as herb and leaves were fed to the silkworm larvae at home. Traditionally farmers planted Dalbergia sissoo trees on the border of mulberry fields but later on they started planting other trees. A few farmers uprooted their mulberry bushes and converted to Swietenia macrophylla plantation. Some farmers converted their entire land to Mango and Litchi chinensis orchards for long term gains. Besides, some traditional farmers, around 10% still continued with silkworm rearing for their livelihood security but planted few rows of trees like Tectona grandis, D.sissoo, Bombax ceiba, S.macrophylla and Acacia auriculiformis. Few big farmers converted their mulberry fields into ponds for fishery, however, planted Mango and Sissoo on border. The first crops inside the tree plantations were Maize, Papaya and Vegetables which gave farmers quick income. Later, Banana and Citrus were planted. These activities are still continuing, but timber harvesting has also started which will give high returns. These forest tree based land changes not only provided sustainable income growth to farmers, but also made them drought resilient leading to climate change mitigation and adaptation besides conserving plant biodiversity.
