Abstract As urban areas and land-use constraints grow, there is increasing interest in utilizing urban spaces for food production. Several studies have uncovered significant potential for urban growing to supplement production of fruit and vegetables, focusing on one or two cities as case studies, whilst others have assessed the global scale potential. Here, we provide a national-scale analysis of the horticultural production potential of urban green spaces, which is a relevant scale for agri-food and urban development policy making using Great Britain (GB) as a case study. Urban green spaces available for horticultural production across GB are identified and potential yields quantified based on three production options. The distribution of urban green spaces within 26 urban towns and cities across GB are then examined to understand the productive potential compared to their total extent and populations. Urban green spaces in GB, at their upper limit, have the capacity to support production that is 8x greater than current domestic production of fruit and vegetables. This amounts to 38% of current domestic production and imports combined, or >400% if exotic fruits and vegetables less suited to GB growing conditions are excluded. Most urban green spaces nationally are found to fall within a small number of categories, with private residential gardens and amenity spaces making up the majority of space. By examining towns and cities across GB in further detail, we find that the area of green space does not vary greatly between urban conurbations of different sizes, and all are found to have substantial potential to meet the dietary needs of the local urban population. This study highlights that national policies can be suitably developed to support urban agriculture and that making use of urban green spaces for food production could help to enhance the resilience of the national-scale food system to shocks in import pathways, or disruptions to domestic production and distribution.

The study was conducted with the objectives to determine the market availability of animal sourced foods (ASF) and fish, and their share in the supply of biomass and protein through visiting the wet markets of metropolitan and municipality areas of Rajshahi district, Bangladesh. A preset questionnaire was used for recording the biomass weight of different ASF and fish in every four days interval in March, 2016. It was found that the supply of ASF (beef, chevon, chicken and egg) and fish in the metropolitan markets (80.20 and 35.89 t/d, respectively) was significantly higher (P<0.05) than any municipality wet market in the district (7.66 and 3.03 t/d, respectively). The market supply of biomass and its protein value of ASF were 3.64 and 4.33 times higher than fish. The chicken shared the highest amount of protein (28.19 %) followed by fish (26.8%), beef (26.21%), eggs (11.46%) and chevon (7.34%) during the study period. However, this initial work does not include milk, and the wet market of ASF and fish may have seasonal variations which needs to be explored through further research. In addition to them, socioeconomic status of consumers and regional variations are important which needs to be studied for addressing resource base safe food production help the strategic reduction of food insecurity in the country by 2030.Res.

Abstract Maintaining food production while reducing agricultural pollution is a grand challenge under the threats of global climate change, which has exerted negative impacts on agricultural sustainability. How agricultural nitrogen use and loss respond to climate change is rarely understood. Here we show that climate change leads to inequality of cropland nitrogen use and loss across global regions based on historical data for the period 1961-2018 from 143 countries. Increases of yield, nitrogen surplus and nitrogen use efficiency (NUE) are identified in 30% of countries, while reductions are observed for the remaining 70% of countries, as a result of climate change. Farm size changes further intensify the inequality of nitrogen use and pollution in global croplands. Yet, enlarging farm size can facilitate climate change adaptation, by which global cropland NUE could be increased by one-third in 2100 compared to 2018 under future shared socioeconomic pathways. Our results would be of great significance to sustain global agriculture as well as eliminate national inequalities on food production and agricultural pollution control.

Trade Offs

Agricultural systems are heterogeneous across temporal and spatial scales. Although much research has investigated farm size and economic output, the synergies and trade-offs across various agricultural and socioeconomic variables are unclear. This study applies a GIS-based approach to official Brazilian census data (Agricultural Censuses of 1995, 2006, and 2017) and surveys at the municipality level to (i) evaluate changes in the average soybean farm size across the country and (ii) compare agricultural and socioeconomic outcomes (i.e., soybean yield, agricultural production value, crop production diversity, and rural labor employment) relative to the average soybean farm size. Statistical tests (e.g., Kruskal–Wallis tests and Spearman’s correlation) were used to analyze variable outcomes in different classes of farm sizes and respective Agricultural Censuses. We found that agricultural and socioeconomic outcomes are spatially correlated with soybean farm size class. Therefore, based on the concepts of trade-offs and synergies, we show that municipalities with large soybean farm sizes had larger trade-offs (e.g., larger farm size was associated with lower crop diversity), while small and medium ones manifest greater synergies. These patterns are particularly strong for analysis using the Agricultural Census of 2017. Trade-off/synergy analysis across space and time is key for supporting long-term strategies aiming at alleviating unemployment and providing sustainable food production, essential to achieve the UN Sustainable Development Goals.

ABSTRACTThis article explores the phenomenon of in-kind remittances of maize and its implications for rural household livelihoods and food consumption. Interviews with a sample of 391 households in eight villages in Malawi are used to substantiate the discussion. Explanations for in-kind remittances are sought in the micro-level interaction between the formal market realm, informalised exchange systems and the household. Remittances are not connected to lower commercialisation levels, suggesting that the explanation for remittances should be sought in the production and consumption patterns of the households. Remittances function as an important redistributive mechanism for food across space. The role of smallholder food production for urban livelihoods as well as the subsistence responsibilities of rural households are underestimated if agrarian household level linkages from rural to urban areas are not recognised in national production and consumption surveys and among policy makers.

This paper addresses <i>(ex ante)</i> the issue of the potential impact of the modulation of direct payments on a sector and regional scale in the Czech Republic. The ultimate version of the compulsory modulation measure adopted under the Health Check of the Common Agricultural Policy (CAP) assumes the reduction of direct payments if the total individual claim exceeds 5 thousand € or 300 thousand € level. The Czech agricultural sector will be impacted by this measure substantially, given the large scale farming enterprises. In 2013, the total farmers’ direct payments will be cut by more than 10% (€ 91 million). Moreover, there are regional differences in farm structures (the average farm size and the extent of collectivization) which will bring about various effects of policies in the heterogeneous regions. The analysis further shows that the regions that are least affected are at the same time more environmental sensitive and are mostly situated in the mountainous or sub-mountainous parts of the country or more urban areas than the average. Hence the effect of the modulation, from a purely environmental perspective, may not contradict the objectives of other environmental policies. That is to say the regions that need support the most will be reduced the least. However, the picture is less obvious in the regional economies where more rural regions (potentially more vulnerable with socio-economic problems) tend to be more affected.

Purpose The purpose of this review of the literature is to provide readers a foundation of understanding whereby future research can move forward in the quest for global sustainable food production. Design/methodology/approach This review includes up-to-date information from evidence-based sources on hydroponics. Topics included are advantages, limitations, nutritional quality and sensory quality Findings Hydroponic growing systems offer the opportunity to at least augment traditional soil-based growing systems in global food production. Some benefits of hydroponic growing systems are limitation of water waste (recirculation), crops grown in controlled environments (control of pests, nutrients and attributes required for optimal plant growth) and ability to manipulate conditions to maximize production in limited space (vertical gardens). Practical implications The human population is increasing with a parallel increase in the demand for food; therefore, food production must increase to meet the need. Originality/value In spite of the rapid interest and proliferation of information by laypeople, evidence-based research is scant on hydroponics. This article provides a summary of the literature on hydroponics and how it may be used for sustainable food production in arid and urban areas.
