Urban food availability and consumption in Grand Lomé, Togo: A household perception analysis

Introduction: Food well-being of the population is one of the priorities of the Togolese government, which relies on the agricultural investment and food security Programme to increase national food production. In addition, the country relies on food imports to make up the shortfall. At the same time undernourishment and malnutrition remain high among the country’s population. This research analyzes food supply and its implications for household consumption in Grand Lomé, Togo. [Methods] The methodology used documents, a survey of 963 heads of household randomly sampled households and semi-structured interviews with 10 households and with Togolese food safety agency (ANSAT). Quantitative data were processed and analyzed using Excel spreadsheets R and R-Studio, while content analysis was applied to the verbal applied to the verbal statements collected. Results: Firstly, the results show that domestic agricultural production contributed an average of 91% of food supply between 2014–2017. The deficit is made up by food imports, which rose from 13.5% in 2014 to 15.4% in 2017. This translated into an acceptable food energy consumption of 2337 Kcal/head/day in 2017. Secondly, 81% of respondents recognize a strong food presence at consumer markets, except that the chi-square test applied to the data at the 5% threshold shows (p-value < 2.2 × 10−16), indicates that this satisfaction is a function of place of residence. Despite this, persistent shortages affect more staple crops, livestock and dairy products, leading households to deprive themselves and buy food at affordable prices. Finally, we observe non-diversified diets marked by regular consumption of “cereals/legumes”, vegetables and beverages to the detriment of “tubers/roots”, “meat/fish”, “fruit” and “dairy products”. Conclusion: This research shows that food supply, although adequate, is not sufficient to ensure balanced, nutritious and culturally appropriate food consumption by urban households. Recommendations: To meet these challenges, the central government, in collaboration with urban communes and consumer advocates, must mobilize resources to create urban agricultural farms, strengthen food protection systems, distribute staple products directly to households and limit the importation of food that is hazardous to health.

Respon Pertumbuhan dan Hasil Microgreens Beberapa Varietas Tanaman Caisim (Brassica juncea L.) pada Berbagai Jarak Tanam

The diminishing amount of land available for agriculture and the growing demand for nutritious food have made it necessary to find alternative sources of fresh vegetables. Urban farming, especially the cultivation of microgreens, can help meet this demand. Microgreens offer several advantages, such as time and cost savings, and they require minimal space while growing quickly. However, the optimal spacing for different types of microgreens is not extensively documented, as research on microgreens is still limited in Indonesia. The Brassicaceae family is one of the most commonly cultivated families for microgreens. This study was carried out at Room A, Faculty of Agriculture, Singaperbangsa Karawang University, Campus 2. The experimental method used was a factorial randomized block design (RBD Factorials) with two treatments for varieties and three for spacing, repeated five times, resulting in 30 experimental units. Factor I, Varieties, consisted of v1 (Tosakan) and v2 (Shinta). Factor II, Spacing, consisted of j1 (1 cm x 1 cm), j2 (1 cm x 2 cm), and j3 (2 cm x 2 cm). The data were analyzed using an analysis of variance (Uji F) at a 5% level. If the results of the analysis of variance were significantly different, the study continued with a multiple range test (DMRT) at a 5% level to determine the best-performing treatment. There was an interaction between the treatments for microgreen varieties and spacing on parameters such as plant density, dry weight of the plant, and fresh weight. There was a significant effect of the variety on the parameter of chlorophyll content, and a significant effect of spacing on the parameters of plant growth rate and the age of leaf appearance. Additional types of plants are needed to determine significant differences related to spacing and their interactions.

Urban agriculture and urban planning: a case of Bangalore between the 1950s and the 1970s

With urbanisation moving at a faster pace than ever before, discussions on Urban Agriculture (UA) and its role in sustainable development have taken centre stage. The implementation of UA has its challenges, one of them being how urban development frameworks view it. This paper examines the disappearance of a historic UA landscape in Bangalore, India between the 1950s and the 1970s, a period of post-independence urban planning. Using historical records including urban planning documents, government files, and oral histories that I recorded with a traditional community of UA practitioners—the Vahnikula Kshatriya—in Bangalore on their memories of the 1950s–1970s, I argue that colonial frameworks in post-independence urban development plans not only displaced UA but also continues to affect it. This paper highlights the urgent need to change how urban planning in formerly colonised places approaches UA.

Urine luck: Environmental assessment of yellow water management in buildings for urban agriculture

The increasing global demand for agricultural production poses challenges to maintain the needs for critical fertilizers such as nitrogen. This study explores the potential of human urine as a source of renewable nitrogen for fertilizer production. Through a life cycle assessment, three different urine management strategies were compared: (S1) an artificial wetland, (S2) an on-site lab-scale aerobic reactor for nitrogen recovery, and (S3) a centralized wastewater treatment plant. While scenario S2 had the highest impacts in 6 out of 8 categories, an advantage in marine eutrophication was identified. S2 showed high energy demand (750 kg MJ-eq) and ecotoxicity (602 kg 1.4-DCB-eq.) mainly due to energy requirements. Nitrogen production exceeded 2.3 times the yearly nitrogen demands of the building tomato production. Upscaling S2 reduces impacts up to 2 times, lowering the payback time from 29 to 13 years. Therefore, implementing large-scale nitrogen recovery systems in cities is encouraged.

Sustainable agriculture impacts in urban settings make the case for federal investments [Policy brief

Urban agriculture has flourished in American cities under the care of communities, but its growing popularity faces a number of challenges related to scant funding, insecure land tenure, and environ­mental pollution. Both local and national policy in the U.S. have struggled to adequately address those challenges and meet the demand for fresh food, local production spaces, and resilient communities. In this policy brief, we explore an emerging apparatus to support urban agriculture in the U.S. Department of Agriculture: The Office of Urban Agriculture and Innovative Production. We describe the relation­ship between urban agriculture’s many bene­fits and future funding, technical assistance, and data collec­tion initiatives through this office. Specifically, we call for consistent, permanent funding that is not subject to the annual federal budget process, which could power more tailored technical assistance programs, reformed granting initiatives, and expanded data collec­tion to inform future policy and practice. Urban agriculture has the potential to transform communities and the future of farming, and federal policy has the potential to provide important support for this transforma­tion. The policies outlined here offer a roadmap for this support.

A classification scheme for urban agriculture combining technical properties with characteristics related to the economic and social sustainability

Urban agriculture is often associated with sustainable agricultural practices. However, the variety of systems qualifying as urban agriculture and the limited information available about their sustainability question this direct relationship. To better understand differences in intra-urban agriculture systems and their sustainability, this paper proposed an holistic classification of urban agricultural systems and collected knowledge about the environmental, social, and economic sustainability of these systems. Such a classification is important to evaluate sustainability claims on urban agricultural systems, anticipate potential sustainability trade-offs between urban agricultural systems and propose preventive measures to address these, and ultimately guide the sustainable deployment of these systems. Compared with existing classifications, the novel classification scheme proposed here accounts for technological, social and economic characteristics of urban agriculture systems to better distinguish between all systems. It was built on 91 scientific papers. The economic intensity of production was, for example, an important characteristic to coherently group urban agriculture systems. The intensity of cooperation between all actors was another characteristic emphasized for certain urban agriculture systems. One end of the classification scheme describes ground-based open, socially motivated urban agriculture systems with high cooperation intensity and low production intensity. The other end of the classification scheme describes building-integrated quasi-closed systems with high production intensity. In between, we find: building-integrated conditioned systems, ground-based conditioned systems, and building-integrated open systems. Mapping sustainability claims from literature in the classification scheme supported its definition along the three characteristics. For example, urban farming was associated with job creation, food safety, water savings, and higher yields while urban gardening with educational potentials, biodiversity improvements, and lower yields. Their display in the classification scheme was therefore supported. To further support the use of the proposed scheme, additional quantitative research to better understand and quantify the sustainability of urban agriculture systems is required.

Urban green spaces and public realm design in Cairo: Enhancing quality of life and environmental sustainability

The paper explores the pressing challenges and promising initiatives in enhancing urban green spaces and the public realm in Cairo, a metropolis grappling with rapid population growth and environmental degradation. As the city struggles with density, air pollution, and a shortage of green areas—far below the recommended standard for urban health—the article highlights key efforts to revitalize public spaces. Notable projects include the creation of large parks like Al-Azhar Park, the redevelopment of the Nile riverfront through projects such as Mamsha Ahl Misr, and the introduction of green infrastructure solutions like street trees, green roofs, and sustainable urban drainage systems. Despite these advancements, Cairo faces significant obstacles, including limited public land, budget constraints, and water scarcity. However, there are opportunities to address these challenges through innovative urban agriculture, public-private partnerships, and community participation in green space development. The paper suggests that through continued investment and thoughtful urban design, Cairo can foster a more sustainable, livable environment. By integrating green infrastructure into future development projects, the city holds potential to transform its landscape and improve the quality of life for its residents in the coming decades.

Assessing pollinator richness on urban-grown mountain mint (Pycnanthemum spp.) populations

ABSTRACT Pollinators provide important ecosystem services in human-developed areas, including pollination for urban green spaces and agriculture. As developers aim to become more eco-friendly, understanding pollinator dynamics in these settings will help enhance pollinator services. Mountain mint plants (Pycnanthemum spp.; Lamiaceae) are commonly grown in urban green spaces and may provide resources to a large range of pollinators. There is a limited understanding, however, of the Pycnanthemum spp.–pollinator relationship. In this study, we used visual monitoring and DNA barcoding to evaluate flower visitor richness over the extended bloom duration of two native species of Pycnanthemum spp. in the greater Richmond area of Virginia (USA). We recorded a total of 85 taxa on Pycnanthemum muticum and 43 on Pycnanthemum tenuifolium flowers. In most cases, our visual monitoring results were confirmed or refined with DNA barcoding, enabling us to build a flower visitor barcode library for the region. The taxon assemblages varied between the two observed Pycnanthemum spp. in general, and over time, demonstrating that these plant species provide resources across taxa and are therefore good candidates for bolstering pollinators when developing urban green spaces.

Promoting active ageing: The positive impact of older people’s participation in Urban Gardens

Abstract Background The socio-health and economic consequences of the progressive population ageing constitute a global challenge for public health, which is committed to the promotion of active and healthy ageing as a strategy to mitigate these consequences. The European project U-GARDEN has evaluated from a comprehensive and innovative approach the impact of urban gardens on the promotion of active ageing through the participation of older people in urban agriculture. Methods A qualitative methodology was designed and implemented in order to analyse the information provided by people over 65 years of age, who actively participated in urban gardens, from a personal and subjective perspective through semi-structured in-depth interviews. The benefits obtained from participation in urban gardens were analysed, considering the different dimensions that make up the paradigm of active ageing: physical, psychological, economic, health, behavioural and personal impact. A total of 20 interviews were used to reach the saturation point. Results Qualitative analysis showed multiple benefits of active and healthy aging. Participants reported increased physical activity and psychosocial improvements such as higher personal satisfaction, reduced stress, and enhanced self-esteem, strengthening community connections and fostering a sense of belonging. Economically, they reported savings on food costs and increased food security. Overall, respondents noted improvements in general health and quality of life, highlighting urban gardening as valuable for well-being and social-economic integration. Conclusions The findings reported in the framework of the U-GARDEN project support the importance of implementing innovative strategies that encourage participation in urban gardens as a tool to improve the overall wellbeing and health of older people, effectively addressing some of the main challenges of ageing such as loneliness unwanted frailty and disability. Key messages • The U-GARDEN project is an example of good practice in the use of urban gardens as a platform for promoting active and healthy ageing. • The promotion of green spaces through the establishment of urban gardens should be considered by health and political authorities for their ability to promote the general well-being of society.

The Application of Smart Drip Irrigation System for Precision Farming

Managing water resources in urban areas is relatively expensive due to the costs of electricity and water distribution from wells and water companies. Therefore, water resource management for urban agricultural purposes needs to be made efficient, such as through smart irrigation technologies, one of which is the drip irrigation system that engages soil moisture sensors and the Internet of Things (IoT) to control the amount of distributed water. This study aims to apply and evaluate the performance of a drip irrigation system based on soil moisture sensors and IoT in urban agriculture. The results showed that the distribution uniformity in the system was identified at fair levels, with a Coefficient of Uniformity (CU) of 90.15% and 86.58%, respectively. Furthermore, our study also found that the IoT-assisted drip irrigation system that engaged a Deep Neural Networks (DNN) model to meet the water requirement led to better peanut yield than the irrigation system based on soil moisture as a control.

Optimizing Growth of Melon (Cucumis melo L. cv. Madesta) in Nutrient Film Technique and Drip Irrigation Hydroponics with Varied Substrates

Hydroponic systems offer a promising solution for urban farming and the utilization of unproductive land. Successful implementation, however, requires careful optimization to select the most effective hydroponic system tailored to specific plants and environmental conditions. This study aims to compare the growth and physiological responses of Madesta melons (Cucumis melo L. cv. Madesta) cultivated using the nutrient film technique (NFT) and drip irrigation system (DIS) with variations in growth media. The Madesta melon seeds underwent a two-week germination phase in coco peat media, followed by transplanting into NFT and DIS setups utilizing diverse growth media, including rice husk, rice husk mixed with compost, and compost only. Over four weeks post-cultivation, assessments were conducted on key growth metrics such as leaf count, leaf diameter, plant height, and stem diameter. Plant physiological responses were also analyzed, encompassing chlorophyll and nitrogen levels, along with the mineral composition within leaves and fruits. Results revealed that the DIS cultivation outperformed the NFT in terms of growth outcomes. Among the varied media combinations, the rice husk and compost blend supported growth most effectively. Notably, no significant differences were observed in leaf and fruit nitrogen content between the DIS and NFT systems, and the overall mineral content of the media remained relatively stable before and after the cultivation period. Mineral content analysis revealed calcium as the predominant element in the leaves, while potassium emerged as the most abundant mineral in the fruits. This research sheds light on the potential of hydroponic systems, specifically the DIS method, for enhancing melon cultivation, emphasizing the importance of selecting appropriate growth media to maximize plant growth.

Green horizons: Exploring the potential of vertical green walls

The term “Green walls” also known as vertical gardens or living walls has emerged as a promising solution to combat the environmental challenges posed by rapid urbanization. This review explores the concept ornamental, plant choice suitable and benefits associated with green walls in urban settings. Utilising vegetation to cover vertical surfaces, green walls offer several benefits to the environment, society and economy. They contribute to improved air quality, noise reduction, energy conservation and biodiversity enhancement. Vertical greenery allows for the utilization of unused wall surfaces, creating green areas without occupying valuable ground space, which is often scarce in urban environments. Additionally, green walls offer aesthetic appeal, promote urban agriculture and create opportunities for community engagement. However, their implementation requires careful consideration of factors such as structural integrity, irrigation and maintenance. Despite these challenges, green walls offer a sustainable and innovative approach to enhancing the quality of urban life while mitigating the negative impacts of urban development on the environment. The current emphasis highlights the significance of green walls as an effective tool in sustainable urban planning, underscoring the need for further research and their integration into urban planning practices.

Assessing the Potential Impacts of Contaminants on the Water Quality of Lake Victoria: Two Case Studies in Uganda

Nutrients are essential for the growth of aquatic life; however, in excess, they can result in a decline in water quality, posing serious risks to both human and aquatic organisms. Human activities, such as urbanisation, industry, and farming, can increase the amount of nutrients and other elements that reach receiving waterbodies like Lake Victoria in Uganda, which can be problematic at elevated levels. There is therefore a strong need to evaluate recent changes in pollutant concentrations and their potential negative effects. To contribute to this gap and to explore the pollutant changes in Lake Victoria, a series of water chemistry data (phosphate, nitrate, potassium, ammonium, sodium, sulphate, silica and chlorine) was collected between 2016 and 2023 in Uganda’s Napoleon Gulf (NG) and Murchison Bay (MB), primarily by the Ministry of Water and Environment (MWE). These locations were chosen based on their vicinity to expanding urban centres and agriculture, and they are also areas where fishing frequently occurs. The datasets were collected at different water depths (0.5–24 m). Data were analysed with the use of IBM’s Statistical Package for the Social Sciences (SPSS 28.0) software and confirmed the excessive concentrations of pollutants within MB compared to NG. The analysis identified the different nutrient types that exceeded internationally recognised thresholds relating to acceptable water quality during the data collection period. Seasonal variations were observed, during the dry season; nutrient levels, however, in NG showed higher nutrient concentrations during the wet season. The study’s capacity to inform local authorities and policymakers about such potential major sources of pollution is of crucial importance for beginning to address the potential impacts on human health and aquatic life.

Urban Open Space Utilization for Subsistence Agriculture: A Study of Esikhaleni Township

Employing a mixed-methods approach, the study conducts structured interviews with local farmers and in-depth interviews with municipal officials from the uMhlathuze Municipality. The findings highlight food insecurity, the necessity for accessible fresh produce, agricultural passion, and rising food costs as primary drivers compelling Esikhaleni residents towards open space farming. Moreover, the research underscores the significant contribution of open space agriculture to the livelihoods of Esikhaleni residents, including improved access to fresh food, reduced food expenditures, and supplementary income generation through produce sales. The study concludes by recommending the integration of urban agriculture into urban planning efforts to safeguard land for agricultural purposes, thereby enabling residents of Esikhaleni Township to engage in sustainable agricultural practices.

PENDAMPINGAN KOMUNITAS POKDARWIS PILANG DALAM PENGELOLAAN ANIMAL WASTE MENJADI KOMPOS ORGANIK UNTUK MENDUKUNG SUSTAINABILITY URBAN FARMING

Animal waste management is an environmental challenge that can be turned into an economic opportunity through the right approach. This service program aims to assist the Pokdarwis Pilang community of Probolinggo City in managing animal waste into organic compost to support the sustainability of urban farming. The Asset-Based Community Development (ABCD) approach is used to empower the community by utilizing existing local assets, such as animal waste, community skills, and infrastructure support. The service process includes five stages: Discovery, Dream, Design, Define, and Destiny. The Discovery stage focused on identifying local assets, where animal waste was found to be a valuable asset that was previously not managed properly. Through the Dream stage, the community formulated a shared vision to create a sustainable waste treatment system. The Design stage implemented technical training and procurement of composting infrastructure. At the Define stage, the community began to manage the waste treatment independently, followed by an evaluation of the results and social impact at the Destiny stage. The results showed an increase in the technical skills of Pokdarwis members, the establishment of a compost production unit, and changes in community behavior in waste management. In addition, the formation of partnerships with local markets helped improve the economic welfare of the community. The ABCD approach has proven effective in creating sustainable social change through community empowerment. Recommendations from this program are to expand the application of the ABCD approach to other communities and strengthen collaboration with stakeholders to support the sustainability of waste management and urban farming.
