The relevance of urban agroforestry and urban remnant forest for avian diversity in a densely-populated developing country: the case of Port-au-Princ…
2021
9 pages; International audience; Urban green spaces can contribute to conserve some of the original avian diversity in urbanized landscapes. However, the relative contribution of urban agriculture vs. urban forest remnants to the preservation of the avifauna in large cities, particularly in developing countries in the tropics, remains poorly documented. We assessed bird assemblages in the densely-populated capital city of Port-au-Prince in Haiti, one of the poorest countries in the world. From early January to late April 2018, 10 censuses per site were conducted in 16 urban green sites, consisting of 8 unexploited, private forest patches and 8 agroforestry plantations, embedded within the u…
Urban gardens and institutional fences: The case of communal gardens in Turin
2017
Urban gardens take on different forms and meanings, which vary depending on the socio-economic context where they located/used and how it evolves over time. This makes a garden comparable to a micro-social ecosystem, different from other gardens and ever changing. As with every social-ecosystem resulting from a territorialisation process, there is a certain degree of social inertia that makes it difficult for outsiders with new motivations and demanding new spaces to enter into the "garden ecosystem". Drawing on existing literature and fieldwork in two urban communal gardens in Turin, the paper is mainly concerned with the spatiotemporal dimension of urban gardening, with a special focus on…
Beyond Alternative Food Networks: Understanding Motivations to Participate in Orti Urbani in Palermo
2019
Community gardens include many benefits, and different motivations seem to underline citizens’ choices to participate. In Italy, political motivations are considered one of the main reasons for participation in community gardens (known as orti urbani). Drawing from the orti urbani experience in Palermo (the largest city in Sicily, Southern Italy), this study aims to understand the main motivations that influence citizens’ participation and to measure the effects of these motivations on fruit and vegetable consumption among participants. Findings reveal that orti urbani attract middle‐class participants who possess high amounts of cultural capital but relatively less financial capital. Among…
Energy-environmental assessment of the UIA-OpenAgri case study as urban regeneration project through agriculture
2020
Abstract Sustainable agriculture is strongly promoted by Agenda 2030 and peri-urban agriculture is considered strategic for agri-food sustainability. Although, innovative farming practices are being implemented, the analysis of their impacts often does not reach the required depth. Within the EU project ‘UIA-OpenAgri - New Skills for new Jobs in Peri-urban Agriculture’, a regeneration process of a peri-urban area in Milan (Italy) was started, through the development of an innovative food hub. 28 innovative foodchains are assessed by a Life Cycle Assessment approach based on primary data collected from the involved start-ups. Non-Renewable Cumulative Energy Demand and the Global Warming Pote…
Ecological risk assessment of pesticides in urban streams of the Brazilian Amazon
2022
Abstract The use of pesticides in households and peri-urban areas of the Amazon has increased notably during the last years. Yet, the presence of these contaminants in Amazonian freshwater ecosystems remains unexplored. Here, we assessed the exposure to 18 pesticides and 5 transformation products in the Amazon River and in the urban streams of Manaus, Santarem, Macapa, and Belem (Brazil). Pesticide concentrations were analyzed by liquid and gas chromatography methods. Ecological risks were assessed following a two-tiered approach. First, hazard quotients and an overall hazard index were calculated using toxicity data for standard test species of primary producers, invertebrates, and fish. S…
Mani verdi per la città. Scenari di agricoltura urbana multifunzionale nella Piana dei colli a Palermo
2015
L’agricoltura periurbana multifunzionale è considerata una strategia efficace per arginare il dilagare dell’urbanizzazione nelle aree rurali, contrastare la pressione urbana e al contempo rendere le città più abitabili e vitali. Dalla prospettiva urbana, le aree agricole intercluse sono soggette a maggiori pressioni da parte del mercato immobiliare e sebbene assolvano molteplici funzioni nei riguardi della città, non sempre sono riconosciute come infrastruttura naturale d’interesse pubblico, come bene comune da tutelare in quanto paesaggio agro-urbano e da collegare a sistemi ambientali più ampi. L’articolo esplora il concetto di agricoltura multifunzionale e lo applica ad un sistema di are…
Reducing electric and thermal energy needs in buildings by using innovative envelope materials - Laboratory results of bio-composites embodying tomat…
2018
The life style of building occupants is continuously arising towards conditions that are more comfortable involving, on turn, the growing of the electric energy consumptions for climatization purposes. This calls for the improvement of the efficiencies of equipment along with environmental performance of building materials. Laboratory analyses of samples of mixed materials, utilizing tomato stems harvested in Sicily and Cataluña, have been conducted Thermal conductance and mechanical properties have been detected for different rates of bio-component and inert materials. First results of the thermal properties seem to situate such bio-composites among the insulating building materials, for a…
Environmental assessment of a new building envelope material derived from urban agriculture wastes : the case of the tomato plants stems
2023
Abstract Purpose Decarbonizing cities is one of today’s biggest challenges. In this regard, particular attention has been paid on improving the environmental performance of buildings. In this framework, this work consists in assessing the environmental impact of an innovative building envelope component derived from urban agriculture (UA) wastes. In fact, rooftop UA seems to be a possible solution to the rising food demand due to increasing urban demographic growth. Consequently, rooftop UA wastes need to be treated in sustainable ways. Methods This study aims to determine the carbon footprint and embodied energy of a new infill wall material, derived from UA wastes produced by a building r…
Privātmāju dārzi pilsētā
2019
Maģistra darba tēma ir „Privātmāju dārzi pilsētā”. Maģistra darba mērķis ir izpētīt privātmāju dārzu nozīmi pilsētnieku dzīvē un pilsētvidē. Darbā izvirzīti četri pētnieciskie jautājumi: kā pilsētu dārzi tiek skaidroti teorētiski; kādas ir dārzu īpašnieku piešķirtās nozīmes dārziem; kādas funkcijas tie pilda; kāda ir privātmāju dārzu ietekme uz pilsētvidi. Pētījuma teorētiskajam ietvaram izmantoti dažādi sociālo zinātņu teorētiskie skatījumi: pilsētas lauksaimniecības perspektīva, pilsētplānošanas teorijas un simboliskā interakcionisma teorija. Darbā izmantotas kvalitatīvās pētījuma metodes: daļēji strukturētas intervijas ar privātmāju dārzu īpašniekiem, novērojumi, kā arī dokumentu analīze…
PROGETTARE L’ADATTAMENTO. Resilienze di agricoltura urbana nel contesto europeo
2022
I crescenti fenomeni legati al cambiamento climatico spingono le città a sviluppare piani di resilienza che possano rispondere in termini di sostenibilità ambientale, sociale ed economica. Le strategie nature-based possono rappresentare una soluzione; tra queste l’agricoltura urbana può contribuire ad aumentare la resilienza dei tessuti urbani europei. Questa attività è stata più volte oggetto di interesse in periodi di crisi come impegno comunitario dai caratteri sociali, oltre che produttivi ed educativi. Attraverso un excursus storico e una successiva analisi di casi studio contemporanei, il paper fornisce strumenti progettuali per intervenire nel costruito con strategie che spaziano dal…
