« Deirdre O’Mahony, artiste et archéologue des savoirs techniques indigènes »
2022
Les projets participatifs et collaboratifs de l’artiste irlandaise Deirdre O’Mahony, ancrés dans le monde rural du Burren, valorisent le patrimoine vernaculaire et les savoir-faire indigènes. Ses recherches de terrain portant sur l’évolution du paysage abordé comme milieu et les collaborations multiples qu’elle entreprend aboutissent à des propositions artistiques revisitant le land art. Ses interventions dans le paysage sont souvent complétées par des propositions dialogiques, dont le repas partagé, qui invite les participants à explorer l’histoire des lieux, les jeux de pouvoir qui s’y tissent et la pertinence des savoirs vernaculaires pour les enjeux de demain, notamment en matière de sé…
A prioritised inventory of crop wild relatives and wild harvested plants of Tunisia
2022
AbstractAn inventory of crop wild relatives (CWR) and wild harvested plants (WHP) occurring in Tunisia, based on the integration of the last available floristic checklists, is presented. The taxa were prioritised according to economic value of the related crop, potential for crop improvement, threat status, endemism, inclusion in the ITPGRFA (Annex I) and average annual contributions to dietary energy (kilocalories) per capita per day by applying a scoring system based on 4 priority levels. Of a total of 2912 taxa belonging to the Tunisian Flora, 2504 CWR and/or WHP (86% of the total), from 143 families and 686 genera, were identified, 2445 of which are CWR and 847 are WHP. In detail, 1654 …
Security Standards Applied to Drinking Water
2021
This chapter presents security standards as applied to drinking water, based on the assumption that freshwater sources face huge threats for humankind both qualitatively and quantitatively due to uncertain global changes, namely population growth, rapid urbanization, and climate change. The study investigates whether the International Featured Standards (IFS—Food), which are complementary to HACCP (Hazard analysis and critical control point), can be used as a system of indicators to measure water security. The case study focuses on bottled water, by identifying structural and contingent risk factors for water as essential food and investigates the suitability of the IFS instrument as an ind…
Early assessment of crop yield from remotely sensed water stress and solar radiation data
2018
Soil moisture (SM) available for evapotranspiration is crucial for food security, given the significant interannual yield variability of rainfed crops in large agricultural regions. Also, incoming solar radiation (Rs) influences the photosynthetic rate of vegetated surfaces and can affect productivity. The aim of this work is to evaluate the ability of crop water stress and Rs remotely sensed data to forecast yield at regional scale. Temperature Vegetation Dryness Index (TVDI) was computed as an indicator of crop water stress and soil moisture availability. TVDI during critical growth stage of crops was calculated from MODIS products: MODIS/AQUA 8-day composite LST at 1 km and 16-day compos…
Two decades of discussion on charitable food aid in Finland : analysing the framing by and through the media
2016
Jo kaksi vuosikymmentä virallisen sosiaalipolitiikan rajapinnoilla toiminut ruoka-apu on murrosvaiheessa: Tulisiko toiminta hiljaisen hyväksynnän sijaan tunnustaa, jolloin avun kohdentamista ja järjestämistä voidaan avoimesti kehittää yhdessä kirkon, kunnallisen sosiaalitoimen ja yksityisen sektorin kesken? Onko toiminnan fokus siirtymässä väliaikaiseksi tarkoitetusta akuutin nälän torjunnasta kohti sosiaalipoliittisen ruoka- köyhyyden ja ekologisen ruokahävikin ongelmat yhdistävää ratkaisumallia? Julkisen, yksityisen ja kolmannen sektorin yhteistyönä toteutettavan saksalaisen ruoka-apumallin (Berliner Tafel -ruokapankkiverkosto) rantautuminen Suomeen (Yhteinen Pöytä …
Justice in transitions: Widening considerations of justice in dietary transition
2021
Just transition is gaining increasing attention. The need to consider social justice in sustainability transitions is finally being acknowledged. Research on this issue has, to date, mainly concentrated on energy systems. In this paper, we examine how the elaboration of dietary transition widens the spectrum of justice questions in sustainability transitions research. We explicate the arising normative questions along the dimensions of distributive, procedural and recognitive justice; widening the considerations further to restorative and cosmopolitan justice. Dietary transition widens the justice considerations to basic needs, food security and nutrition. By doing so, it evokes socio-cultu…
Indicators of agricultural intensity and intensification: a review of the literature
2015
Since the 1960s, research has dealt with agricultural intensification (AI) as a solution to ensure global food security. Recently, sustainable intensification (SI) has increasingly been used to describe those agricultural and farming systems that ensure adequate ecosystem service provision. Studies differ in terms of the application scales and methodologies, thus we aim to summarize the main findings from the literature on how AI and SI are assessed, from the farm to global levels. Our literature review is based on 7865 papers selected from the Web of Science database and analysed using CorText software. A further selection of 105 relevant papers was used for an in-depth full-text analysis …
Right to Food and Geoengineering
2023
AbstractClimate change poses grave risks to food security, and mitigation and adaptation actions have so far been insufficient to lessen the risk of climate-induced violations of the right to food. Could safeguarding the right to food, then, justify some forms of geoengineering? This article examines geoengineering through the analytical lens of the right to food. We look at the components of food security and consider how the acceptability of geoengineering relates to the right to food via its impacts on these components. Our examination shows that results vary greatly between different forms of geoengineering: while some forms of geoengineering fail to respect the right to food, certain o…
The land grabbing in the international scenario: the role of the EU in land grabbing
2016
The worldwide increase in population and consumption has produced a growing demand for food and energy in the rich and developing Countries. The resulting intensification of land investments, to cope with this need, has in many cases produced investments without transparency rules and it hasn't created real development for local people. The aim of this paper is to identify, through a cluster analysis, homogeneous groups of investor Countries in order to understand the role of the EU Member States in the context of land grabbing. The results show that the strategies adopted by the investors are driven by the need to achieve energy security and reduce CO2 emissions in order to cope with the p…
Technology generation to dissemination: lessons learned from the tef improvement project
2018
Indigenous crops also known as orphan crops are key contributors to food security, which is becoming increasingly vulnerable with the current trend of population growth and climate change. They have the major advantage that they fit well into the general socio-economic and ecological context of developing world agriculture. However, most indigenous crops did not benefit from the Green Revolution, which dramatically increased the yield of major crops such as wheat and rice. Here, we describe the Tef Improvement Project, which employs both conventional- and molecular-breeding techniques to improve tef—an orphan crop important to the food security in the Horn of Africa, a region of the world w…
