Role of Urban Agriculture for Livelihood Improvement, Waste Management and Greening in Case of Hawassa City

Background: Urban agriculture is one of the strategies to enhance the livelihood of the urban community, ensure food security and nutrition. Despite, the increasing development of the practice in Hawaassa city, its environmental and societal perspectives had been neglected. Moreover, the increase in urbanization due to several social-economic reasons has become a challenge for urban agriculture practices. Methodology: This study was aimed at investigating the roles of urban agriculture on livelihood improvement, waste management, and urban greening. A purposive random sampling technique was employed to select sample households. Besides questionnaire surveys and key informant interviews were used to elicit necessary information while literature analysis supplemented the data. Result: It was found that urban agriculture in the study area is maintaining the cultural experience of the local society, generating income, and introducing saving habits. It has also improved the esthetic value of the city via utilization of the organic waste. Hence, urban agriculture in the city is compatible with urban job creation, price adjustment, and provision of a green urban environment. Conclusion: Urban agricultural practices should keep the phase of increasing urbanization in the study area.

Postharvest Losses in Quantity and Quality of Pear (cv. Packham’s Triumph) along the Supply Chain and Associated Economic, Environmental and Resource Impacts

Approximately one third of the food produced globally is lost or wasted along the supply chain. Reducing this would be an important measure to increase the global food supply as the world continues the struggle to feed its people sustainably. Not merely a waste of food, these losses also represent a waste of human effort and agricultural inputs from expensive fertilizers to natural resources as well as contributing to global greenhouse gas emissions. Measuring the extent of, and understanding the reasons for, these losses can assist in developing appropriate measures required to prevent or reduce such losses. Therefore, the objective of this research was to quantify postharvest losses in quantity and quality of ‘Packham’s Triumph’ pears at farm and simulated retail levels. Pears were sampled from two farms in the Western Cape Province of South Africa, the largest deciduous fruit production and export region in Southern Africa. The greatest losses measured along the supply chain were on-farm immediately after harvest, with 18% recorded. The main reasons for on-farm losses were small size (65%), deformity (26%), and chafed peel (9%). After 14 days in cold storage (−0.3 ± 0.7 °C, 81.3 ± 4.1% RH), mean pear losses were 0.86% which increased to 1.49% after 28 days. After 10 days of further storage under simulated market conditions (5.4 ± 0.6 °C, 83.7 ± 2.9% RH), fruit losses were 1.52% during retail marketing and 2.09% during export. Storing pears under ambient conditions (25.1 ± 1.3 °C and 46.6 ± 6.0% RH) resulted in a higher incidence of losses, increasing from 0.90 to 1.55 and 2.25% after 3, 7, and 10 days, respectively. The socio-economic impacts of these postharvest losses amounted to financial losses of between ZAR 492 million (USD 34.1 million according to the conversion rate of 14 April 2021) to over ZAR 831 million annually, and this was associated with the loss of 301 million MJ of fossil energy, 69 million m3 of fresh water and contributed to the emission of approximately 19,690 tons of CO2 equivalent. The fresh water lost could sustain 3.7 million individuals daily for a whole year at a daily minimum usage rate of 0.05 m3 per day while it will require planting 0.5 million trees to sink the 19,690 tons GHG emissions of the pear losses (0.039 metric ton per urban tree planted). Decreasing postharvest losses will conserve resources as well as improve food security and nutrition, objectives of the post-2015 sustainable development agenda led by the United Nations.

COVID-19 pandemic: A wake-up call at science-policy-society to work towards a livable future

The year 2021 is nearing its end when the online version of the journal MASKANA 12(2) is published. 2021, means that already one-fifth of the 21st century has passed. Since 2000 raised the world population from 6.1 to 7.9 billion, or 29.5%. Different models predict that the world population in 2030, the year that the world leaders in Glasgow (UK) during the GOP26 meeting agreed to limit global warming to 1.5°C, will increase to 8.5 billion. Wonder if the world possesses the capacity to secure food, given the continuing exponential growth of the population, and at the same time will be able to limit the warming up of the planet by 1.5°C? According to the yearly study of FAO (Food and Agriculture Organization of the United Nations) on the state of food security increased the number of people experiencing undernourishment since 2014, and today the world experiences an unprecedented setback in its hunger eradication effort. The major drivers behind the decline in food security and nutrition are according to FAO: conflict, climate variability and extremes, and economic slowdowns and downturns. The impacts the people experience are exacerbated by the levels of inequality in terms of income, productive capacity, assets, technology, education and health. The COVID-19 pandemic has been an additional factor that put the world off track to ending world hunger, malnutrition, climate change, immigration, that the rich are getting richer, and the poor are becoming poorer, among other phenomena of inequality. Parallel to these evolutions, democracy worldwide is in decline. According to IDEA (International Institute for Democracy and Electoral Assistance), is the trend of democratic erosion ongoing since 2006 and is today worse than ever before.

The Future of Food Security, Nutrition and Health for Agri-food Systems Transformation

Global progress towards food security and nutrition has been slow in many places and even reversing in others. Against the background of changes in population, income, technology, climate, and other drivers, the pressures on food systems are daunting. When designing and rolling out future interventions towards these goals it is of vital importance to utilize foresight knowledge to anticipate, shape, and prepare for alternative possible futures. Overcoming current and emerging challenges but also seizing opportunities as they present themselves requires continued efforts to provide robust analysis to inform decision making. Here we collated the latest insights from foresight studies around three central aspects within the food system. First, consumer demand and the changes this is undergoing is a key aspect shaping the food system itself as well as nutritional and environmental outcomes. Second, distributional inequalities and trade-offs within the food system have further been identified as key challenges to tackling adverse health outcomes of the current food system. And third, amplified by the COVID crisis, enhancing the resilience of the food system that is increasingly under threat from multiple risks has risen to the top of the agenda.
