Abstract

The co-benefits from the implementation of ecosystem-based approaches in managing land degradation and enhancing ecosystem services have not been adequately explored in the mainstream literature. The study aims at identifying the indicators of land degradation and the associated ecosystem-based approaches used to remedy the situation. The ecosystem-based approaches refer to ecosystems and ecosystem services together with their flexible management in a cultural setting. The paper adopts a descriptive research design with quantitative and qualitative approaches. Principally, it targets 236 smallholder farmers for the survey, key informants for interviews and community members for focus group discussion. The results revealed that land degradation is mainly identified by reduced crop yield (53%). Farmer identification of land degradation is influenced by the age of the farmer (p = 0.001) with  The ecosystem-based approaches include stone bonding, crop rotation, mulching and particularly, composting (53%). The ecosystem-based approaches are statistically linked to the communities with p-value of 0.020. A p-value of 0.001 shows that the ecosystem-based approaches are beneficial in the various study communities. Farmers’ experience over the past five years is statistically related to the age of respondents (p = 0.008). The p-value of 0.000 indicates very strong statistical significance of the challenges of ecosystem-based approaches in the communities. The ecosystem-based approaches have long term goals for sustainable land improvement and may not be realized unless there is direct policy to take care of the approaches even in the short term.

Abstract

The impacts of land tenure security on investment have long been recognized. Land certification has been undertaking in most zones of the region including Jimma zone. Therefore this study assesses farmers’ perception on land certification and factors affecting long term land related investments specifically tree, fruit tree and coffee planting. It was conducted in three Woredas of Jimma Zone namely Omonada, Limmu Kossa and Seka Chekorsa. Multi-stage sampling techniques were employed to select respondent farmers from each Woreda and a total of 200 household heads, of which 79.5% are them secure land certification, were selected for the analysis. The findings’ indicates that most of the respondents have positive and strong agreements with different attributes of land certification. These are land certification encourage investment activities, soil conservation measures, and farmers to venture in area that could enhance productivity, provide increased land tenure, feel sense of ownership and current system is satisfactory, have lifelong use right and support both woman and man to share equally. There is significant relationship between land certification and long term land related investments specially tree and fruit planting. In addition long term land related investments are influenced by total land holding, land certification, oxen ownership, extension service and annual income. Thus, land certification and other socio-economics and institutional factors need to be considered to encourage farmers’ involvement in long term land related investments

Abstract

 As a source of minerals, water must be continuously maintained, including in term of its quality. Meanwhile, swamps are wetlands that have the potential to experience a decline in water quality. The presence of river borders in swamps has been known to maintain their water quality. Vegetation cover of the river border is established through restoration activities in which it is expected, directly and indirectly, to improve water quality. This study aimed to investigate the water quality in swamp using the Water Quality Index (WQI). Surveys were carried out and samples were collected to determine the effect of restoration on river border in swamps. Samples were collected severally, namely prior to restoration (T0), first year (T1), third year (T3) and fourth year (T4) after restoration. The parameters for water quality of T0 and T1 include pH, DO, BOD, TDS, turbidity and nitrate, while for T3 and T4 include: pH, DO, BOD, TDS, temperature, phosphate, E. coli and nitrate. The findings indicated that the WQI of the swamp prior to restoration was greater than that at the first year of restoration due to the process of land clearing. Meanwhile, the WQI at the third year has improved compared to before the restoration and land clearing phase. It suggests that the presence of vegetation on river border is able to improve the water quality. At the fourth year, a fire in the upstream reached the area adjacent to the study site. It led to a decline in surface water quality and affected the water quality index. Furthermore, the abundance of aquatic biota was indicated by two taxa of zooplankton in the third year of restoration while none of them was identified in the fourth year. In overall, restoration activities on the river border improve the quality of water in swamps in a sustainable manner.

Abstract

Soil acidity and problems related to aluminium (Al) toxicity are usually limiting factors for soil use in agriculture. Problems with acid soils can be overcome by liming. Another potential way to overcome problems of acid soils is to utilize young coal enriched with sulfate-reducing bacteria (SRB) or Acidithiobacillus ferrooxidans. The purpose of this study was to assess the utilization of coal enriched with SRB or A. ferrooxidans as an alternative ameliorant to provide transformation of aluminium fractions and phosphorus availability in acid soils. There were two acid soils (Ultisols) studied with differences in the content of exchangeable Al. Al fraction was differentiated into exchangeable Al (Al-exch), crystalline Al (Al-dithionite), non-crystalline Al (Al-o), organic Al bound (Al-p), non-crystalline inorganic Al (Al-po), as low or medium complex with organic matter (Al-Cu), highly stabilized Al complex with organic matter (Al-pCu). The results showed that for acid soils from Jasinga West Java and Lebak Banten, coal or lime ameliorant, microbial A. ferrooxidans or sulfate-reducing bacteria (SRB) and coal or lime ameliorant enriched with A. ferrooxidans or sulfate-reducing bacteria (SRB) significantly affected the value of Al fraction. Coal or lime ameliorant enriched with A. ferrooxidans could reduce the Al fraction content in acid soils. Coal or lime ameliorant enriched with SRB could increase the availability of P in acid soil from Jasinga West Java with the distribution of Al-pCu > Al-dhitionite > Al-po > Al-exch > Al-Cu fraction. Coal or lime ameliorant enriched with SRB could increase the availability of P in acid soil from Lebak Banten with the distribution of Al-pCu > Al-po > Al-dhitionite > Al-Cu> Al-exch

Abstract

Changes in land use will impact on the characteristics of humic acid in the soil due to biotic and abiotic factors. The study aimed to characterize humic acid in soil from various land uses in Tutur District, Pasuruan Regency of East Java. Soil sampling was carried out on six land uses, namely mixed garden, coffee plantation, apple orchard, vegetable garden, pine forest, and conservation forest. Analysis of soil samples included soil chemical characteristics (pH, redox, organic-C, and total-N) and characterization of humic acid included colour ratio of E4/E6, total acidity, carboxyl groups, and phenolic groups. The results showed that the land use of coffee plantation provided the best soil fertility indicated by the contents of humic acid, total-N, organic-C in the soil that were higher than that of other land-uses. The highest humification index was obtained for coffee plantation land use with the measurement of the E4/E6 colour ratio of 4.56 index value. The best characteristics based on the total value of acidity, the -COOH group and the phenolic -OH group were observed in the coffee plantation. This was supported by the characteristic of humic acid through the humification index or E4/E6 colour ratio, as well as the low phenolic -OH value which is a characteristic of fulvic acid.

Abstract

Cassava effluent has become a subject of growing environmental concern in developing countries largely due to ineffective disposal methods. In this study, the impact of land disposal technique by processors in Ayetoro, Ogun State Nigeria was investigated. Soil samples were collected from three disposal sites scattered across the study area at depths of 0 cm, 15 cm, 30 cm and 45 cm. Results were compared with samples obtained from control sites at a distance of 5 m from the disposal sites. The physicochemical parameters determined includes soil pH, silt, sand, clay, organic carbon, exchangeability acid, pH, total nitrogen, average phosphorous, zinc, lead, iron, sodium, copper, calcium, potassium, magnesium and manganese. The result show that the pH varies significantly across the sites. The highest concentration was recorded for phosphorous while the lowest concentration was obtained for total nitrogen. The highest concentrations were recorded at the soil surface while the lowest were recorded at 45 cm depth. Idagba recorded the highest pollutant concentration and while the lowest were obtained at kano. The activities and discharge techniques of processors had negatively impacted the soil quality which may also affect the ground water quality. There is a need to take proactive measures to protect the environment through adequate sensitization and enforcement of environmental laws.

Abstract

Land cover change is an urgent global issue that needs to be addressed immediately. Its dynamics are of the greatest importance to Key Biodiversity Areas (KBAs) along the Wallacea Corridor, including Buano Island, whose land and sea are rich in biodiversity. KBA Buano Island is home to endemic and endangered birds, such as Moluccan scrubfowl (Eulipoa wallacei) and black-chinned monarch (Monarcha boanensis). Black-chinned monarch only lives on the island (single-site species). Buano waters have an interestingly diverse life, including dugong (Dugong dugon), hawksbill turtle (Eretmochelys imbricata), loggerhead turtle (Caretta caretta), and many species belonging to the dolphin family (Delphinidae) and beaked whale family (Ziphiidae). This study was designed to analyze and map the spatial-temporal patterns of land cover changes on Buano Island. It employed a multi-temporal analysis on Landsat images from 1970, 1980, 1990, 2000, 2010, until now, and a t-test to analyze the results further. The t-test analysis produced t-count ≥ t-table at confidence level (α) of 0.05, indicating significant changes in land cover from 1970, 1980, 1990, 2000, 2010, until 2016. These multitemporal-spatial dynamics were attributable to fluctuation in population growth and open and straightforward access between the island and the capital of the regency. Furthermore, from the aspect of fishery and maritime affairs, Buano Island already had synergistic land area development.

Abstract

Most of the activities of the use of organic fertilizers and natural additions of organic matter in agricultural intensification fields in Indonesia have not been able to compensate for the rate of decline in soil organic matter by the decomposition process. Biochar has a high C level and has the mean residence time in a long period in the soils. It has been proven that biochar applications may increase soil Carbon but have not been able to increase plant production. Therefore, the use of biochar combined with organic waste rich in nutrients is essential to develop. The purpose of this study was to determine the effectiveness of some biochar compositions with sugar cane, chicken manure, fish waste in the form of biopellet fertilizer on improving the chemical properties of sandy soils and the vegetative growth of soybean plants. This study used a completely randomized block design with two factors. The first factor (B) was the composition of biochar consisting of three levels, namely: 70% biochar, 15% chicken manure, 15% fish waste (B1), 50 % biochar, 25% chicken manure, 25% fish waste (B2), and 20% biochar, 40% chicken manure, 40% fish waste (B3). The second factor (D) was the dose of biopellet fertilizers consisting of four levels, namely: control (D0), 2.5 t/ha (D1), 5 t/ha (D2), and 10 t/ha (D3). The results showed that the addition of biopellet fertilizer effectively improved soil chemical properties (pH, C-organic, and CEC) and the availability of N, P, and K of the sandy soil. The effectiveness of increasing the soil total-N varied from 32.42 to 75.79%, P-available varied from 17.46 to 40.69%, and exchangeable K ranged from 8.7 to 25.67%. Improvement of soil chemical properties and the availability of N, P, and K by biopellet fertilizer application increased plant growth but reduced the weight of root nodules.

Abstract

Heavy metal contamination was an environmental and human health problem all over the world. Cadmium is the most hazardous heavy metals due to its high mobility and toxicity at low concentrations. Lead (Pb) also belongs to the hazard element caused by its prolonged persistence in the soil. This study aimed to develop the remediation techniques on polluted land, i.e. a combination of biochar and indigenous plant. The biochar was produced by slow pyrolysis method. This experiment was conducted at the farmland at Sumber Brantas, Malang, East Java. We used rice husk and tobacco waste biochar, and Eleusine indica (L.) Gaertn and Rorippa sylvestris (L.) Bess. as remediator plants. The results showed that rice husk biochar had a significant effect on pH value and potassium content (p = 0.0001; p=0.0004). On the contrary, the soil nitrogen content, soil organic-C content, and soil cation exchange capacity applied with tobacco waste biochar application were higher than that applied with rice husk biochar (p = 0.03; p=0.00001; p = 0.00001). The improvement of soil characteristics increased the growth of Eleusine indica and Rorippa sylvestris as indicated by the plant height and biomass. The addition of biochar could promote the growth of remediator plant and enhanced the accumulation of Pb and Cd in the plants. Mixtures of rice husk biochar and tobacco waste biochar caused Eleusine indica more effectively absorbed heavy metals than Rorippa sylvestris on all types of biochar treatments; Eleusine indica absorbed Pb and Cd higher than Rorippa sylvestris as shown by Pb and Cd contents in the soil.

Abstract

Bojonegoro Sub-district is the capital of Bojonegoro District, East Java Province, Indonesia. This area has quite high economic growth supported by large oil and gas reserves in the district. An increasing number of population and improving economy will cause more water needs. People in this area use groundwater as their main source for daily purposes. However, information on the potential of groundwater resources is not yet well available. Therefore, the study aims to determine groundwater flow patterns, the distribution of aquifers, and groundwater geochemistry. The study was conducted by measuring groundwater level as many as 42 points; both dug wells and deep wells, 18 points geo-electrical surveys, and chemical analysis of eight groundwater samples. The results showed groundwater flow direction into the Bengawan Solo River with the primary aquifer of the sandstone lens. All groundwater samples indicate that the type of groundwater is calcium magnesium bicarbonate (Ca2+ - Mg2+ - HCO3-) and come from one system. High nitrate content was found in some areas, probably due to contamination from agricultural or urban wastewater. Therefore, it needs some actions for groundwater protection and conservation in this area to support the sustainable use of groundwater.
