Abstract

Tailings of post-tin mining land have the potential to be cultivation fields for eggplant, but the problem from post-tin-mining land is the low essential nutrient and high metal contents. The quality of land needs to be improved by providing ameliorant such as oil palm empty fruit bunch compost. This research aims to determine the best dosage of oil palm empty fruit bunch compost to production and metal uptake of eggplant in post-tin mining land. This research was conducted from January to May 2019 in post-tin mining land, Dwi Makmur Village, Bangka. This research used a randomized block design with six treatments and four replications. Treatments consisted of organic fertilizer (control) of 15 t/ha(K0), oil palm empty fruit bunch compost 20 t/ha(K1), 30 t/ha(K2), 40 t/ha(K3), 50 t/ha(K4), and 60 t/ha(K5). The results showed that the application of oil palm empty fruit bunch compost of 60 t/ha was the best dose to increase eggplant production in the tailing of post-tin mining land. Application of oil palm empty fruit bunch compost reduced metal absorption of eggplant fruit in tailing of post-tin mining land.

Abstract

One of land degradation problems in Nawangan is surface erosion, throughout the years it widespread. Land conservation by planting plantations in the potential disturbed area is one way to solve this problem. Grass jelly or locally known as janggelan (Mesona palustris BI.) can be an alternative for this land conservation, Nawangan has suitable geographic location and grass jelly cultivation is profitable for the surroundings economically. Aim of this study was to evaluate land suitability for grass jelly to solve the land degradation problem in Nawangan. Purposive sampling methods were used to determine sample point, then soil sample analyzed in a laboratory, and overlay of type of soil map and land use map. After soil characteristic was obtained, then the matching process was used. Finally, from this study showed that land suitability classes in Nawangan for grass jelly are very suitable on (S1) land unit LaS and LaK, suitable (S2) on land unit Lil, LiH, LiS and LaH, and marginal suitable (S3) on land unit LaL and LiK.

Abstract

Gold mine tailing soil media is characterized by low soil fertility and heavy metals toxicity. As an effort to improve the condition of gold mine tailing soil media, a revegetation experiment using Arbuscular Mycorrhizal Fungi (AMF) and soil media from gold mine tailing was conducted in the greenhouse. The objectives were to assess initial growth, P uptake and Pb reduction in Nauclea orientalis L. plants inoculated with indigenous AMF grown on gold mine tailing soil media. Three AMF fungi were used in this study, i.e. Glomus aggregatum, Glomus sp. and Acaulospora delicata. The experiment was conducted in Completely Randomized Design, having four treatments, i.e. control, G. aggregatum, Glomus sp. and A. delicata. The experiment was carried out for 3 months in a greenhouse scale. The results showed that local AMF inoculation significantly increased the height and stem diameter of lonkida by 181-213% and 284-443%, respectively, compared to control. The highest measurements of leaf’s length and width of lonkida seedlings were obtained from Glomus sp. and A. delicata treatments. Glomus sp. and A. delicata each significantly increased P levels in roots and shoots. Inoculation with G. aggregatum reduced Pb in the root and shoots parts by 74-86% and 72-76%, respectively, compared to controls. Local AMFs are potential to be developed as biological fertilizers to support revegetation in degraded lands, such as in gold mine tailing areas.

Abstract

This review paper aims to review on the causes and consequences of land degradation in Ethiopia. The results from different literatures indicate that the major factors that cause land degradation in Ethiopia are: clearing woodland for agriculture , repeated cultivation, removal of residuals and dungs, single cropping, extraction of wood, , population growth, deforestation, soil erosion, low technology, inadequate extension services, political instability, cultivation on steep slopes, overgrazing, traditional way of cultivation, heavy wind, high intensity of rainfall, drought and landslides, absence of all-inclusive land use and lack of land use plans developed. On the other hand, the depletion of forests and vegetation, loss in water resources, decrease in the quality and quantity of livestock, enhancing the unemployment rate and out-migration, conflict between pastoralists, food insecurity, deceasing of soil fertility and arable land, reduction of agricultural productivity, increasing price of farm inputs, reduction of plants grown, depletion of aquifers, loss of biodiversity, reduction of potable water, shortages of timber, climate change and desertification are the major consequences of land degradation in Ethiopia. Afforestation, Reforestation, terracing, crop rotation, mixed cropping, irrigation schemes and traditional soil conservations are among the coping strategies that Ethiopian farmers are using. To overcome this problem, strengthening the teamwork among policy makers, GOs/NGOs, local communities, research institutes and the mass media are the key agents that must take these responsibilities.

Abstract

Local cassava processing industries produce large quantities of wastewater containing cyanide which is toxic in nature with negative impacts on the environment when disposed without treatment. In this study calcined periwinkle shell (CPS) was prepared, characterized and used to adsorb cyanide present in cassava wastewater. Equilibrium studies were conducted in batch set ups to investigate the influence of process variables such as adsorbent dosage, pH, temperature, contact time and initial cyanide concentration on the adsorption process. The highest removal rate of cyanide from cassava wastewater was found to be 78.34% with equilibrium reached at fixed adsorbent dosage of 3.0 g at contact time of 80 minutes. Cyanide adsorption was also observed to be dependent on pH with the maximum adsorption of cyanide occurring at a pH 10. The percentage of cyanide removed decreased with increase in cyanide concentration. Results from the study confirm calcined periwinkle shell as low cost and effective adsorbent which can be used for the removal of cyanide from cassava wastewater

Abstract

Pyroclastic materials from Mount Kelud eruption which deposited in surrounding areas has very low nutrient availability. Fertilizer efficiency is normally low due to a coarse texture. This research was an attempt to increase nutrient availability using zeolite and organic matter in combination with inorganic fertilizers. The materials was treated with three rates of inorganic fertilizers (100%, 70%; 40% of the recommended rates, i.e. Urea 400 kg/ha; SP-36 150 kg/ha, and KCl 75 kg/ha), in combination with three types of amendments (zeolite, Tithonia diversifolia leaves, and cow manure at the rate of 20 t/ha), and 100% inorganic fertilizer treated materials as control, and incubated for 60 days. Soil samples were taken every 10 days after incubation and analysed for soil pH, C-organic, available N, P, K content measurement. The results showed that total N content increased with the rates of inorganic fertilizers. At 10-20 days after incubation the content of NH4+ is greater than NO3- but gradually changed after 30 days after incubation. Apparently, zeolite treated materials had lower NH4+ content than organic treated samples at 10-20 days after incubation, however at 60 days after incubation its NO3- content was relatively higher than Tithonia leaves treated samples. At 60 days after incubation, the higher the fertilizer rates, the higher the content of available P and exchangeable K. The highest content of available P and exchangeable K occurred respectively in cow manure and Tithonia diversifolia leaves treated materials. Until 60 days after incubation, organic treated materials had a higher amount of available and exchangeable K than zeolite treated materials, because they originally contain considerable P and K. However, at 60 days after incubation, zeolite treated materials contained the highest amount of NO3-. This indicated that zeolite had a higher capability to retain mineral N, hindering N removal from leaching and volatilization. A higher nutrient holding capacity could be related to the increasing cation exchange capacity after the addition of amendments, and to a lesser extend to pH and % C.

Abstract

This paper reviews the effects of habitat loss and human influence on the survival of Black-crowned cranes in Africa. Black-crowned crane is distributed through Sahel and Sudan Savannah regions of Africa, ranging from the Senegal basin and Guinea-Bissau drainage in West Africa to the western Ethiopian Highlands and south-west Rift Valley in East Africa. Habitat loss, transformation and degradation, and illegal capture and trade for pet industry, are the major threats of the species. Because of habitat loss, the population of Black-crowned cranes is declining across its home range and it is even disappearing in some countries in West Africa. It is predicted that the population decline will continue in the future due to habitat loss and trapping of cranes for domestication. The species is classified as Lower Risk from 1988 to 2000, Near Threatened from 2004 to 2008, and then Vulnerable from 2010 onwards. The rapid conversion of wetlands and intensive land use and different economic development with poor environmental protection threat the survival of Black-crowned cranes. In order to overcome the threats of Black-crowned cranes (Balearica pavonina), habitat conservation and community awareness are essential, not optional.

Abstract

Restaurant Wastewater (RW) is characterized by high volume and strength, with minimal treatment before its release into the environment. Electrocoagulation (EC) could be a better alternative due to its environmental friendliness. The study investigates the use of EC in RW treatment. The samples were collected from the University of Ibadan student Union Building restaurant, between 7-9 am. The EC consisted of an aerator, carbon electrodes, power source, a beaker, and stirrer. Electrodes were connected in mono-polar system at inter-distance of 10 mm, with retention times of 0, 30, 60 and 90 minutes. The RW was aerated before passing direct currents of 0.25, 0.5, 0.75, and 1.0 Amperes. The Colour, Particulate Phosphorus (PP), Soluble Reactive Polyphosphate (PO43-), Phosphorus Pentoxide (P2O5), Chemical Oxygen Demand (COD) and Dissolved Oxygen (DO) were determined. The study was three replicates. Mean percentage removal efficiencies for PP, PO43-, P2O5, COD, DO and colour at 30 minutes (16.85, 19.33, 17.15, 12.58, -32.88 and 20.12%), 60 minutes (30.88, 27.1, 30.57, 21.13, -57.18 and 34.30%), and 90 minutes (40.75, 33.00, 32.83, 25.83, -87.88 and 40.7%) respectively. Better treatment efficiencies of treated wastewater using the electrolytic reactor were obtained with an increase in direct current passing through.

Abstract

Forests are one of the most valuable ecosystems in the world, containing over 60% of the world’s biodiversity. This ecosystem has multiple social economic values, apart from its intrinsic value.  Forest provides a sustainable environment. Deforestation leads to the disappearance of sustainable development. Deforestation takes place due to multiple of reasons like logging, population growth, urbanization, grazing, construction of dams and reservoirs, habitat fragmentation, slash and burn method of farming, wildfire, global warming, hydroelectric projects. Agriculture is considered to be the backbone of the Ethiopian economy and almost 85% of the societies in Ethiopia engage in agriculture.  The agricultural sector in Ethiopia in particular and in Africa, in general, is highly affected by deforestation directly and indirectly. Therefore, this paper focuses not only on the causes and consequences of deforestation but also seeks for better alternatives to tackle deforestation in Ethiopia

Abstract

In order to maintain or improve the soil fertility of agricultural systems in Ngaoundere, an experiment on the decomposition of simple litters and mixtures of Harungana madagascariens, Vitelaria paradoxa and Syzygium guineense var. macrocarpum was conducted in a field using the litterbag method. This experiment was made of single species and their mixtures of which gave three uneven mixtures (5VP, 5HM and 5SM) and one even mixture (3E) amounting to seven treatments (THM, TVP, TSM, 3E, 5HM, 5VP, and 5SM). The experimental design was a completely randomized block with three replications. 126 samples of 10 g each were introduced in a field for 24 weeks and a deduction of 3 samples was made at 2, 4, 6, 10, 16 and 24 weeks. The remaining dry mass, rates of decomposition, half time and the nutrient release in the soil were determined. The results showed that the remaining dry mass varied from 67.95% in TSM (S. guineense) to 22.02% in TVP (V. paradoxa). The rate of decomposition ranged from 0.033 for 5SM (mixture 50% of S. guineense and 25% for each of the two other species) to 0.055 in 3E with respectively 19, 64 to 12, 56 as a half-time. The initial chemical content and that at the end of the experiment of the simple and mixed litters varied significantly within the treatments. The mixture of litter released more nitrogen and carbon than the individual litter and the pattern was ranged as follow 3E>5VP>5HM>5SM>TVP>THM>TSM. The pattern of phosphorus release in the soil was ranged in the following order: TVP>TSM>THM>5VP>3E>5HM>5SM, indicating that the individual litter released more phosphorus on the soil than their mixture. These preliminary results will not only contribute in the comprehension of the decomposition process mechanism of Ngaoundere but also will permit in choosing the type of the litter and mixture with release more nutrient in the soil for improvement of agricultural system fertility.
