Journal of Wetlands Environmental Management is an international journal that publishes authoritative and original articles on topics relevant to freshwater, brackish and marine coastal wetland ecosystems. The Journal serves as a multi-disciplinary forum covering key issues in wetlands science, management, policy and economics. As such, Wetlands Environmental Management aims to encourage the exchange of information between environmental managers, pure and applied scientists, and national and international authorities on wetlands policy and ecological economics.

Abstract

This research aimed to analyze potential supply and removal of biomass and soil nutrients induced by different vegetation on peatlands. The research was carried out in peats dome of the catchment area of the Sibumbung River and the Burnai River in Pedamaran Sub-Districts, OKI South Sumatra. The research method used field survey of case studies of four natural phenomena (swamp grass, bush swamp, pulai peatlands, and peat forest). The research resulted that the highest production and harvest of biomass came from peat forest, pulai peatland, bush swamp and swamp grass. The highest biomass supply to the soils were given by the peat forest, pulai peatland, bush swamp and swamp grass (around 12,545; 11,593; 7,491 and 5,313 kg/ha/year respectively). The more varied the vegetation type, the higher the supply of soil nutrients. Swamp grass and bush swamp have low vegetation diversity and are mostly dominated by alang-alang. Swamp grass and bush swamp showed the same pattern and the order of nutrient supply in the highest sequence is K, Ca, N, Mg, Ca, and P. The supply order of soil nutrients (peat forest and pulai peatland) showed a similar pattern, namely from the highest content of Ca, N, K, Mg and P. Pulai vegetation can be recommended for a paludiculture system because it resembles almost the peat forest in producing biomass and soil nutrient supply to the soils and is originally native plant from peatland.

Abstract

 AbstractSouth African wetlands are disappearing at a rapid rate. Considering the vital functions they provide, they require optimal protection and, where appropriate, restoration. In line with protecting and restoring the environment, section 28 of South Africa’s National Environmental Management Act 107/1998 (NEMA) makes provision for the duty of care and remediation of environmental damage (DOC). This enforceable duty rests upon every person (natural and juristic) to, amongst others, prevent pollution or degradation of the environment or to stop, minimise, and rectify such pollution or degradation by taking certain measures. For wetlands, this duty is bound to the idea of 'ecological restoration’ (ER), which is defined as “the process of helping to recover an ecosystem that has been degraded, damaged or destroyed”. This paper, through the selected theoretical framework for ER, sets out the literature to provide the foundation for 1. the international obligation of restoration; and 2. a critical analysis of section 28 of NEMA through the selected ER framework for wetlands ecosystems. The research reveals the gaps in support of the argument that the DOC principle may lack in addressing the full embodiment of ER and providing the consequences of such failure. Thus, calling for the amendment of section 28 of NEMA (DOC) to include the appropriate provisions and the removal of superfluous and confusing provisions such as ‘significant’. However, there is scope for the improvement and development of ER for the 2024 proposed National Joint Wetland Management Policy..

Abstract

Tidal lowland reclamation aims to extend food agricultural area. Land clearing was done at Delta Telang II, Kabupaten Banyuasin District, South Sumatra I period of 1981-1982. Most area of Delta Telang II had land typology of B/C and almost half of it already been changed into palm oil plantation. Therefore, the field study had been conducted to determine the potentials and constraints for development of paddy field.  The research method was applied study and field experiment. Soil physical properties analyzed were texture, volume weight, and hydraulic conductivity.  Rice used in this study was Inpara 3 variety. The research results showed that soil physical properties was appropriate for development of paddy field rice. Controlling of water level in tertiary level by farmers was a key succeeds to provide water for crops. Model of water gate is flap gate type and it is operated dominantly as drainage during rice growth period and only functioned as supply when crops entering generative phase. Average rice production was 7.5 t ha-1. This condition was showed that using proper water management, balance fertilizer application, and adaptive rice variety resulted in successful rice crops cultivation at tidal lowland area and subsequently prevent land functional shifting.  Key words: Tidal lowland reclamation, water management, rice.

Abstract

The research was to determine the potential of various species of organic vegetable from bamboo, taro, rattan and eggplant group from Central Kalimantan as fungicide and bactericide. In vitro testing of botanical pesticides used two types of fungi, namely Colletotrichum capsici and Sclerotium roflsii), and one pathogenic bacteria, namely Xanthomonas campestris. The results showed that several organic vegetable extracts from taro and rattan could control C. capsici, S. roflsii and X. campestris. It was proven that extract plant from immature fruit of Solanum ferox, mature fruit of S. lasiocarpum, leaf of S. torvum, tuber of Xanthosoma sagittifolium, leaf and midrib of Colocasia esculenta, C. esculenta and C. esculenta, fresh leaf of Dendrocalamus asper, stem inside of rattan Calamus trachycoleus  and Daemonorops fissa against growth of S. rolfsii. It was also found that four type of plant extracts could control C. capsici (that is fresh leaf of S. lasiocarpum and S. torvum, tuber of C. esculenta, leaf and midrib of X. sagittifolium). This study was the first to report that plant extracts from fresh leaf and mature fruit of S. ferox, mature fruit of S. melongena, leaf and midrib of C. esculenta, fresh leaf and stem of D. asper, stem of B. vulgaris var striata, skin and stem inside of C. trachycoleus and skin of D. fissa can inhibit growth of X. campestris bacteria. Hance, non-vegetable and organic vegetables from Central Kalimantan had potential as botanical pesticides.

Abstract

The objective of the study was to determine the relationship between physical properties (specific gravity, moisture content, and shrinkage) and bonding strength of Jabon wood; and between wettability and bonding strength.  The results showed that the variable of bonding strength and physical properties had a close relationship, it was shown by R2 = 87.5% and r = 0.93, especially on tangential shrinkage.  In addition to physical properties, the wetting property of Jabon sawdust can be used to estimate bonding strength.
