Market demand for maize (Zea mays L.) in Indonesia is increasing from time to time along with the increasing demand for food and livestock for fodder. However, current farming practices in the upland area where maize usually cultivated, threaten the sustainability of maize production. Conservation farming could be an alternative to reduce land and soil degradation caused by current farming practices. A factorial randomized block designed field experiment was conducted to determine the combined effect of biogeotextile with cover crop residues and soil tillage on growth and yield of maize. The treatments included utilization of Mendong plant’s mat (Fimbrystilis globulosa) as biogeotextile material and four cover crop species: Sunn hemp (Crotalaria juncea), Cowpea (Vigna unguiculata), Pigeon pea (Cajanus cajan), and Mucuna (Mucuna spp). The results showed that the biogeotextile mat and cover crop residues, but not soil tillage, increased maize height and the number of leaves, and yield of maize. Biogeotextile mulch increased maize yield up to 43% compared to control. The highest yield (8.0 t/ha) was shown by the combination of biogeotextile application with cowpea residues. Conservation farming is prospective for improving plant production and protecting land from degradation.

In recent decades, climate change causes distressful shocks upon the poor people’s natural resources and socio-economic processes from local up to global scales. The crisis is more severe in Ethiopia, where harsh ecological changes are frequent. Therefore, the objective of this study was to determine the vulnerability levels of rural communities to climate change and natural resources scarcity in Debark woreda, Northwest Ethiopia. Livelihood Vulnerability Index (LVI) and IPCC methods were used to analyze the data. The meteorological data reveal a declining precipitation trend by 61.13 mm in the past 31 years whilst maximum and minimum temperatures increased by 0.62 0C and 0.74 0C respectively. The LVI result indicates that the Debark community is highly vulnerable with land (0.59) and forest (0.57) scarcity. Water scarcity (0.50) and climate exposure (0.30) put them in a vulnerable class. Both the total LVI (0.48) and LVI-IPCC (-0.69) approaches placed the woreda community again in a vulnerable position. The findings imply that climate change should be placed within the broader context of development strategy and rural poverty reduction. Particularly, concerted efforts should be exerted to participatory integrated watershed management strategies supported with farmers training to ensure sustainable development of natural resources. Farmers’ best natural resource conservation practices should be incorporated in the local plans.

Coal mining activities have a negative impact on the ecosystem and lead to the disruption of the environment due to waste disposal containing a high concentration of Fe and Mn. In addressing the problem, the biological reclamation approaches using LCC (Legume Cover Crop) is performed to anticipate the acidic condition of soil pH and high concentration of Fe and Mn. This study aimed to determine the effect of a combination of several types of LCCs, i.e., Centrosema pubescens, Calopogonium mucunoides and Pueraria javanica in combination with Bokashi fertilizers application for improving soil chemical properties and the efficiency of Fe and Mn uptake. The results showed that the combination of LCC and bokashi fertilizers had a significant impact on raising soil C-Organic, P and K along with the increasing of Fe and Mn uptake. Pueraria javanica had the highest value of BCF (BioConcentration Factor) of Fe and Mn uptake at the level of 0.72, and 0.56 %, respectively and this crop is more potential crop as phytoremediator than Centrosema pubescens and Calopogonium mucunoides. Canonical Variate Analysis could distinguish the position and distance among the treatments based on selected parameters.

As morphometric investigation is connected to prioritization of watershed, morphometric analysis has got a significance role in light of soil and water conservation. In this study, an endeavour for the examination of point by point morphometric analyses of sub-basins was accomplished through the measurement of linear and shape parameters by using ArcGIS-9.3 software. Specifically, linear and shape morphometric parameters like stream length, stream order, drainage density, stream frequency, bifurcation ratio, Length of overland flow, basin perimeter, form factor, compactness coefficient, elongation ratio has been considered. The SRTM DEM (30 x 30 m) is processed for the delineation resulting in 61 sub-basins. The morphometric parameters which affect the soil erodibility are considered to organize the sub-basins and relegate positions on the premise of their association with erodibility to get compound parameter (Cp) esteem. Based on the value of Cp the sub-basin with the lowest Cp value was given the highest priority and then categorized the sub-basins into three classes as high, medium and low in terms of priority. Accordingly, high priority zone comprises 11 sub-basins, medium 19 and low 31 sub-basins. The sub-basins which are falling under high priority were a great deal more defenceless to soil disintegration and ought to be given high need for land preservation measures.

One of the sectors supporting the economy of Indonesia is the mining industry. In East Kalimantan, coal mining activity has been done widely. Coal-mining open-pit activities play a significant role in the economic growth and the advancement of technology for Indonesia. Therefore, it is necessary to study every critical aspect including the hydrological and hydrogeological studies but especially aquifers, so that mining activities can be well managed and the impact on the environment can be overcome. The study of the aquifer from the study area was based on the resistivity value of the materials obtained through one of the geophysical methods that are the geoelectrical resistivity method, by using Wenner-Schlumberger configuration. In this study, geoelectrical resistivity method was performed in order to find out the condition of the subsurface by injecting two electrodes into the soil using direct current (DC) with certain distance so that potential difference can be known and resistivity information of subsurface layers can be obtained. The obtained resistivity value of the material was then interpreted so that the type of aquifer in the study area can be known. The interpretive results of the resistivity values of the materials in the study area showed that the distribution of aquifers based on measurement of a geoelectrical line of line number one, two and three, ware semi-confined aquifers. Meanwhile, the distribution of aquifers of line number four was confined aquifers. Based on the results of hydrological studies, the area of study has an annual rainfall of 3,053.704 mm/year with a watershed area of 16.586 km2. The evapotranspiration value of the study area is 1,784.21 mm/year, the surface run-off is 913.51 mm/year, and groundwater recharge is 355.98 mm/year.

Sweet potato is the main food resources for human life besides that of rice. An experiment to find out the effect of weeding with two kinds of fertilizer on the growth of yield sweet potato (Ipomoea batatas L.) was conducted at UB Agro Techno Park, Jatikerto, Kromengan, Malang, East Java, from April until to 2017. The experiment used a randomized block design with six treatments consisting of G1 (organic fertilizer + weeding 15 days after planting = DAP), G2 (inorganic fertilizer + weeding at 15 DAP), G3 (organic fertilizer + weeding at 15 and 30 DAP), G4 (inorganic fertilizer + weeding at 15 and 30 DAP), G5 ( organic fertilizer + weeding 15, 30 and 45 DAP), G6 (inorganic fertilizer + weeding at 15, 30 and 45 DAP) with three replications. The results showed that weeding three times (15, 30 and 45 DAP) significantly reduced the dry weight of weeds, improved the growth and yield of sweet potato with two kinds of fertilizers.

In recent years, GIS and Remote Sensing technology has played a vital role in studying urban growth and development. This study is aimed to assess the effects of urban expansion on the surrounding land uses using GIS and Remote Sensing in Debre Tabor Town. Remote sensing data or products such as Aerial photograph (1984), Quick Bird Satellite Image (2000), and Aerial photograph (2016) were used to compute spatial or temporal changes of land use land cover due to urban expansion. ERDAS Imagine and Arc GIS software were used to analyze, model and map the data. The study revealed a significant change in urban boundary and urban land-use land cover between 1984 and 2016. The urban boundary expansion rate between the years 1984 and 2000 was 69.06%, higher than the rate experienced thereafter to the year 2016 (18.86%). However, for the last thirty-two years, between 1984 and 2016, the overall boundary increasement of almost eighty one percent (81.4) was very magnificent. The study also indicated that the area experiencing rapid increase in built-up areas (80.93 %), and agricultural land (23.81%). However, sharp decrease of forest by 36.07%, and open land by 65.02% was seen in the same periods of years. Built-up area expansion was found to have increased by expanding the urban boundary at the expense of open land, agricultural land, and forests. Therefore, integrating GIS and remote sensing technology for urban expansion mapping is a worthy method. Hence, it is recommended that it will be cost effective if the results of this study will be incorporated into ongoing urban planning and land use by concerned bodies.

Environmental degradation, which is caused by the quarry, is a complex problem. The site of the quarry within an agricultural land and forest makes land become critical. Rehabilitation of the area can be conducted by reclamation. Revegetation using local species is no better than pioneer species. Based -on Indonesian regulation-in Permenhut P.4/Menhut-II/2011, revegetation using fast-growing species is important for a precondition before enrichment using climax species, so then it needs an evaluation of land suitability for the fast-growing species. The study of revegetation was conducted at quarry clay which the characteristics of this study were description and exploration with field survey supported by laboratory analysis. Data obtained were analyzed by giving weights and scores of species characteristics to decide selected species of vegetation, then the soil characteristics and qualities were matched with species growth requirements. The results showed that jabon (Anthocephallus cadamba) and sengon (Falcataria moluccana) are selected species for revegetation. Land suitability classes of jabon and sengon are not suitable (N) and land suitability of jabon and sengon can be increased to be marginally suitable (S3) by reclamation using potting system that includes building drainage, improvement of depth, soil pH, application of fertilizer, dolomite, and gypsum, application of grass mulch and collecting large rocks for making the terrace.

Irrigation with textile wastewater and fertilization with an inorganic fertilizer containing lead (Pb) have negative impacts for agricultural sectors, especially lead contamination in a rice field and its uptake by rice plant. The rice grain that contains Pb is dangerous if consumed by humans, so it needs treatment to suppress Pb uptake by rice. Agrobacterium sp. I30 and vermicompost have a role as chelating heavy metals agents. The purpose of this study was to determine the effect of the chelating agents to suppress Pb uptake by rice in Kebakkramat, Karanganyar of Central Java. The method used was the quantitative method through a completely randomized block design with two factors (inorganic fertilizer and chelating agents). The results showed that application of Agrobacterium sp. I30 without inorganic fertilizer decreased Pb content in rice from 5.03 mg/kg to 4.97 mg/kg with a decrease in Pb uptake of 6.28%. Application of vermicompost without inorganic fertilizers decreased Pb content in the rice from 5.03 mg/kg to 1.61 mg/kg, with a decrease in Pb uptake of 72.18%. The use of both chelating agents can be recommended to suppress Pb uptake by rice in polluted soil and increases the safety of rice for consumption.

Mungbean (Vigna radiata L.) productivity in dryland decreased recently due to the soil fertility degradation. The objective of this study was to evaluate the effect of biochar types and cattle manure rates on the growth of mungbean in semi-arid dark soil. The factorial completely randomized block design 3 x 5 with four replicates was set to arrange treatments for the field trial. Two biochars (rice husk and sawdust) at 10 t/ha in combination with four rates of cattle manure (1, 3, 5 and 10 t/ha) and control (without biochar and cattle manure) were applied to the soil, incubated for three weeks and then planted with mungbean cv. Fore Belu. The results revealed that additions of biochar and cattle manure increased soil moisture and soil electrical conductivity by 2-4% and 0.15-0.20, respectively; decreased soil temperature and bulk density by 1-2oC and 0.2 g/cm3, respectively; increased plant height, stem diameter, root length, total, shoot and root dry weights by 4 cm, 0.1 cm, 5 cm, 7 g, 0.9 g and 6 g, respectively, compared to the control. The best growth of mungbean was obtained from the additions of sawdust biochar at 10 t/ha and cattle manure at 3 t/ha.
