Urban farming is one of the strategies that can shape family food security in urban areas. The aquaponic system is one of the urban farming activities. Small-scale aquaponics can be used for household scale. Maximum care is needed in aquaponic cultivation so that the growth and yield of vegetables and fish are good. Aquaponic can be an IRT solution that does not manage daily food expenditure by getting fish and vegetable crops that are harvested per day. The purpose of this community service is to: (1) analyze the frequency of household vegetable consumption, (2) analyze household income (savings) from the application of aquaponics. This study uses a qualitative approach and survey methods and uses income analysis. The results showed: (1) There was an increase in the frequency of eating vegetables in respondents by 9.5%. Before the socialization, the frequency of eating vegetables for households was 90.5%, while after the activity was carried out, the frequency of eating vegetables was 100%. Respondents consume vegetables every day so that they have fulfilled the minimum amount of vegetable and fruit consumption per household member is three portions of fruit and two portions of vegetables or vice versa every day (2) Household food income or saving by applying aquaculture is Rp. 126.000/month obtained from the harvest of vegetables and catfish.

Urban Farming

Countries in West Africa are adversely affected by climate change (erratic rainfall and rising temperature) resulting in floods, desertification, drought and sea level rise. These events are anticipated to have negative impacts on agricultural development on the continent, ultimately, contributing to food insecurity and environmental degradation. This implies that the production capacity of agrarian communities is unable to meet the food demand of the growing urban population. Can sustainable and innovative urban farming technology such as aquaponics achieve food security as well as sustainable development in countries vulnerable to climate change? This study uses inferential statistic to examine the plant growth performance in micro-scale aquaponics and specific growth rate per day (SGR) for the fish growth performance vis-à-vis conventional urban farming production. A quantitative analysis use to examine the barriers to adoption based on survey of (five) urban aquaculture practitioners in Lagos, Nigeria. Literature review was use to assess the economic feasibility of a small-scale aquaponics system in developing countries based on Net-Discounted Benefit-Cost Rate (DBCR). The results suggest that aquaponics can improve food security through fish and vegetable production and it is likely that urban farming practitioners will adopt the technology if support mechanism are in place. Aquaponics systems present a novel opportunity to promote environmental conservation as well as sustainable food production and consumption in urban areas in Western Africa if adequate financial credit and knowledge transfer is provided.

Four Levels

This research analyzes the system of food expenditure based on the household food security level in Central Java. The household food security levels are classified into four levels, consisting of food-secure, food-less secure, food-vulnerable and food-insecure. The data used are the Susenas data in the form of raw data. The results show that there are significant differences in the proportion of food expenditure among the households of food-secure and food-less secure to the households of food-vulnerable and food-insecure. In each level of household food-secure, household expenditure on instant foods and drinks shows the highest proportion compared to other food groups. The more insecure foods in a household, the higher expenditure proportion for tobacco. In each household group based on the level of food-secure, the households in urban areas have a smaller proportion of rice expenditure compared to the households in rural areas. Based on these results, hopefully the handling priority for the foodsecure problem should be better given to the household groups of food-vulnerable and foodinsecure.

Abstract Objectives Dietary pattern analysis has a holistic approach to the eating behaviors of populations. The objective of this study was to identify the patterns of food expenditure (as a proxy of dietary patterns) in Iranian urban households. Methods The study made use of Iran Households Income and Expenditure Survey data in the urban areas that included 18,701 households. Principal components analysis was used to identify major household food expenditure patterns (FEPs) and binary logistic regression models for relation between households’ socioeconomic characteristics with FEPs. Results Four FEPs could be identified: “Affordable and Diverse” (ADP), “Expensive and Modern” (EMP), “Traditional" (TP), and “Cheap and Western” (CWP). Factors that increased the ORs of EMP and CWP had many similarities. Being a child under 5 years old, being a child or adolescent with 6 to 18 years old and being a mother's with a university education level in the household, increased the ORs of these patterns. Also Factors that increased the ORs of ADP and TP had many similarities. Smaller family size, older family, no children under 5, and lower maternal education in the household, increased the ORs of these patterns. The ORs of " ADP" Showed no difference between income quarters rather the ORs of EMP, TP, and CWP In households in the fourth quarter of income compared to the first quarter, were 3.57 (95% CI  = 3.12–4.17), 0.55 (95% CI  = 0.49–0.62) and 0.59 (95% CI  = 0.53–0.67) respectively. Conclusions This study clearly shows the role of mother's education and the presence of children in the choice of household food expenditure pattern and in Iranian urban households, especially households with children, improving household income should be considered along with creating healthier food environments.

Indian mustard plants are the main vegetable crops consumed by urban communities. The need for this vegetable increases along with the increase in culinary tourism in each region and the government's appeal on sustainable food home. One effort made to meet the needs of vegetable mustard in urban areas can be cultivated using polybags. The main problem of vegetable cultivation on polybags is the availability of soil media. To overcome the limitations of soil media it is attempted to substitute it with organic litter enriched with MOL (local microorganisms). The purpose of research is to find the right combination of planting media for mustard plants. The results showed that the composition of K7 = soil: compost: litter of hay: litter of maize (2: 1: 1: 1) best on plant length, number of leaves, length of root leaves and number of roots while the wet weight of mustard plant (g) K7 = soil: compost: litter of maize: litter of corn (2: 1: 1: 1) and K8 = soil: compost: litter of maize: litter of maize: cocopeat (2: 1: 1: 1: 1) or soil: compost + urea. Increased weights of wet mustard by 63% compared to soil media and 20% compared to soil composition: compost + urea. Organic straw in the form of straw: litter of corn stalk: cocopeat enriched with MOL are able to become ready-made planting media on the cultivation of indian mustard plants in polybags.

Although the ratio of sewer systems to population in Japan has been improving in recent years, the construction of sewer systems in small communities such as farming or fishing villages, etc. had lagged behind that of urban areas. However, construction of small-scale sewer systems in farming and fishing villages has been actively carried out in recent years. This report explains the history of the promotion of small-scale sewer systems, why submerged filter beds are being employed in many cases, and introduces the design, operation and maintenance of representative waste-water treatment plants in farming and fishing villages which incorporate de-nitrogen and dephosphorization.

ABSTRACT Generally, the environmental wind speeds in urban areas are relatively low due to clustered buildings. At low wind speeds, an aerodynamic stall occurs near the blade roots of a horizontal axis wind turbine (HAWT), leading to decay of the power coefficient. The research targets to design canards with optimal parameters for a small-scale HAWT system operated at variable rotational speeds. The design was to enhance the performance by delaying the aerodynamic stall near blade roots of the HAWT to be operated at low wind speeds. For the optimal design of canards, flow fields of the sample blades with and without canards were both simulated and compared with the experimental data. With the verification of our simulations, Taguchi analyses were performed to seek the optimum parameters of canards. This study revealed that the peak performance of the optimized canard system operated at 540 rpm might be improved by ∼35%.

Small-scale spatial variability in NO2 concentrations is analysed with the help of pollution maps. Maps of NO2 estimated by the Airviro dispersion model and land use regression (LUR) model are fused with measured NO2 concentrations from low-cost sensors (LCS), reference sensors and diffusion tubes. In this study, geostatistical universal kriging was employed for fusing (integrating) model estimations with measured NO2 concentrations. The results showed that the data fusion approach was capable of estimating realistic NO2 concentration maps that inherited spatial patterns of the pollutant from the model estimations and adjusted the modelled values using the measured concentrations. Maps produced by the fusion of NO2-LCS with NO2-LUR produced better results, with r-value 0.96 and RMSE 9.09. Data fusion adds value to both measured and estimated concentrations: the measured data are improved by predicting spatiotemporal gaps, whereas the modelled data are improved by constraining them with observed data. Hotspots of NO2 were shown in the city centre, eastern parts of the city towards the motorway (M1) and on some major roads. Air quality standards were exceeded at several locations in Sheffield, where annual mean NO2 levels were higher than 40 µg/m3. Road traffic was considered to be the dominant emission source of NO2 in Sheffield.

The use of biofertilizers is important for sustainable agriculture, and the use of nodule bacteria and endophytic actinomycetes is an attractive way to enhance plant growth and yield. This study tested the effects of a biofertilizer produced from Bradyrhizobium strains and Streptomyces griseoflavus on leguminous, cereal, and vegetable crops. Nitrogen fixation was measured using the acetylene reduction assay. Under N-limited or N-supplemented conditions, the biofertilizer significantly promoted the shoot and root growth of mung bean, cowpea, and soybean compared with the control. Therefore, the biofertilizer used in this study was effective in mung bean, cowpea, and soybean regardless of N application. In this study, significant increments in plant growth, nodulation, nitrogen fixation, nitrogen, phosphorus, and potassium (NPK) uptake, and seed yield were found in mung beans and soybeans. Therefore, Bradyrhizobium japonicum SAY3-7 plus Bradyrhizobium elkanii BLY3-8 and Streptomyces griseoflavus are effective bacteria that can be used together as biofertilizer for the production of economically important leguminous crops, especially soybean and mung bean. The biofertilizer produced from Bradyrhizobium and S. griseoflavus P4 will be useful for both soybean and mung bean production.
