Dal 1983 al 1988 l'Irpinia è stata teatro di una delle storie più tristi dello sviluppo industriale della regione Campania, ovvero la vicenda dell'apertura e della chiusura dello stabilimento Isochimica. Una fabbrica progettata per la scoibentazione dei pannelli di amianto dalle carrozze dei treni su commissione delle Ferrovie dello Stato (FS). Se da un lato la storia produttiva della fabbrica è stata molto breve, dall'altro lato l'impatto disastroso che essa ha avuto sul territorio e sulla vita di centinaia di operai è, oggi più che mai, attuale. Infatti, dopo circa 25 anni dalla chiusura della fabbrica, installata in un borgo popolare alla periferia di Avellino (Borgo Ferrovia), gli operai, per la maggior parte ammalati di patologie asbesto-correlate, sono ancora in lotta per veder riconosciuti i loro diritti dalle istituzioni competenti. Inoltre, il sito in cui era collocata l'ex fabbrica non è stato ancora bonificato e centinaia di cubi di amianto sono ancora depositati all'aria aperta in prossimità di scuole, campi di calcio e abitazioni. In questo contesto, l'installazione della fabbrica, la sua attività, la sua chiusura e il successivo occultamento delle responsabilità da parte delle autorità, hanno svelato uno scenario socio-economico e politico che ha anticipato alcune dinamiche di riproduzione del capitale apportate dalla globalizzazione economica. Infatti, l'installazione illegale della fabbrica avvenuta senza i permessi delle autorità, l'organizzazione della produzione che oscillava tra il formale, informale e illegale, le relazioni di lavoro precarie e lo sversamento abusivo di tonnellate di amianto nel territorio circostante, hanno fatto dell'Irpinia, all'inizio degli anni '80, uno dei laboratori delle dinamiche del capitalismo deregolamentato di matrice neoliberista (Harvey 2005; Sennet 2006; Portes, Sassen-Koob 1987). Allo stesso tempo, la vicenda Isochimica si inscrive profondamente nelle storiche relazioni economico-politiche tra il Nord e il Sud dell'Italia in cui le forme embrionali di economia neoliberista si sono riprodotte all'interno di relazioni di potere di natura coloniale (Saitta 2013; Mezzadra 2005; Stoler, Cooper 1997). Dunque, partendo dall'analisi di questo scenario, l'articolo punta a studiare la lotta dei lavoratori dell'ex Isochimica, dalla prima occupazione della fabbrica avvenuta nel 1985 al movimento degli ex-operai dei giorni nostri. L'obiettivo è quello di analizzare nello specifico la lotta operaia degli anni '80 per il diritto a un lavoro sicuro e duraturo, comparandola alle recenti rivendicazioni per per il diritto alla vita. Questo studio prende in considerazione 20 biografie di ex operai dell'Isochimica, focalizzando l'attenzione soltanto su alcune e analizzandole all'interno del quadro politico-economico e istituzionale che, dagli anni '80 fino a oggi, è riuscito è impedire agli operai il riconoscimento dei loro diritti. L'ipotesi dell'articolo è che la lotta degli operai dell'ex-Isochimica, all'interno del sistema di potere locale, sia da inscrivere nei mutamenti del sistema di produzione e di rappresentazione apportato dalle politiche neoliberali in cui, nel caso paradigmatico del Sud Italia, la mistura tra «passato» coloniale e «modernità» neoliberale ha generato nuove forme di subordinazione (Petrillo 2011; Saitta 2013). In questo contesto, le rivendicazioni operaie dei lavoratori dell'Isochimica negli anni '80 e quelle attuali per il diritto alla vita (riconoscimento delle patologie, assegnazione di una rendita sociale, invalidità civile, cure dignitose) sono state estromesse dal terreno del conflitto tra capitale e lavoro in un'epoca in cui la fabbrica non è più il terreno in cui si giocano le lotte per una società più giusta (Fassin, Memmi 2004; Petrillo 2009).

This research focused on the development of sustainable alternative methods to control aphids, giving special emphasis on cultural practices and plant management systems. Increasing the diversity within crops may have several beneficial effects on pest control, creating attractive habitats for indigenous beneficial fauna and simultaneously deterring pests (“push-pull” approach). In this field study, two wheat/pea associations (mixed cropping and strip cropping) where compared to monocultures of pea and wheat. The abundance and diversity of adult aphidophagous beneficials (predators and parasitoids) were accessed weekly, using yellow traps, while aphids were observed directly on plants. All individuals were identified down to the level of species. In both crops, the percentage of aphid infestation and density of colonies were significantly higher in monocultures during the abundance periods. The mixing was particularly beneficial for the pea, while strip cropping was more efficient for the wheat. Concerning beneficials, their abundance was also significantly higher in monocultures, comparing with the other treatments. This study shows that increasing diversity within crops can prevent them from aphid infestations. However, additional methods are needed to attract more efficiently the aphidophagous beneficials, in order to promote the natural control of aphids. [less ▲]

Nowadays, strategies used to control aphids in fields of pea, Pisum sativum L., and wheat, Triticum aestivum L., still rely on synthetic insecticides which have negative effects on the environment and human health. This research focused on the development of sustainable alternative methods, with special emphasis on cultural practices and plant management systems. Increasing the diversity within crops may have several beneficial effects on pest control, creating attractive habitats for indigenous beneficial fauna and simultaneously deterring pests – the ‘push-pull’approach. In this field study, two wheat/pea associations (mixed cropping and strip cropping) where compared to monocultures of pea and wheat. The abundance and diversity of adult aphidophagous insects (predators and parasitoids) were accessed weekly using yellow traps, while aphids were observed directly on plants. In both crops, the percentage of plants infested with aphids and density of aphid colonies were significantly higher in monocultures during periods of aphid abundance. Mixed cropping was particularly beneficial for the pea, whereas strip-cropping was more efficient for the wheat. The abundance of beneficials was significantly higher in monocultures comparing to the other treatments. Quantitative aphid-natural enemy food webs showed that the abundance of the two main ladybird species, Coccinella septempunctata L. and Propylea quatuordecimpunctata (L.), increased with the occurrence of Acyrthosiphon pisum (Harris) on pea plants. Abundance of the two main species of Syrphidae, Sphaerophoria scripta (L.) and Eupeodes corollae (F.), increased with the occurrence of Sitobion avenae (F.) and Metopolophium dirhodum (Walker) on wheat plants. This study shows that increasing diversity within crops can help lower aphid infestations. However, additional methods are needed to more efficiently attract aphidophagous beneficials and promote the natural control of aphids. [less ▲]

This study aims to explore the utility of the impact response surface (IRS) approach for investigating model ensemble crop yield responses under a large range of changes in climate. IRSs of spring and winter wheat (Triticum aestivum) yields were constructed from a 26-member ensemble of process-based crop simulation models for sites in Finland, Germany and Spain across a latitudinal transect in Europe. The sensitivity of modelled yield to systematic increments of changes in temperature (-2 to +9°C) and precipitation (-50 to +50%) was tested by modifying values of 1981–2010 baseline daily weather, with CO2 concentration fixed at 360 ppm. The IRS approach offers an effective method of portraying model behaviour under changing climate as well as advantages for analysing, comparing and presenting results from multi-model ensemble simulations. Though individual model behaviour may depart markedly from the average, ensemble median responses across sites and crop varieties indicate that yields decline with higher temperatures and decreased precipitation and increase with higher precipitation. Across the uncertainty ranges defined for the IRSs, yields are more sensitive to temperature than precipitation changes at the Finnish site while sensitivities are mixed at the German and Spanish sites. Precipitation effects diminish under higher temperature changes. While the bivariate and multi-model characteristics of the analysis impose some limits to interpretation, the IRS approach nonetheless provides additional insights into sensitivities to inter-model and inter-annual variability. Taken together, these sensitivities may help to pinpoint processes such as heat stress, vernalisation or drought effects requiring refinement in future model development. [less ▲]

o improve climate change impact estimates and to quantify their uncertainty, multi-model ensembles (MMEs) have been suggested. Model improvements can improve the accuracy of simulations and reduce the uncertainty of climate change impact assessments. Furthermore, they can reduce the number of models needed in a MME. Herein, 15 wheat growth models of a larger MME were improved through re-parameterization and/or incorporating or modifying heat stress effects on phenology, leaf growth and senescence, biomass growth, and grain number and size using detailed field experimental data from the USDA Hot Serial Cereal experiment (calibration data set). Simulation results from before and after model improvement were then evaluated with independent field experiments from a CIMMYT world-wide field trial network (evaluation data set). Model improvements decreased the variation (10th to 90th model ensemble percentile range) of grain yields simulated by the MME on average by 39% in the calibration data set and by 26% in the independent evaluation data set for crops grown in mean seasonal temperatures >24 °C. MME mean squared error in simulating grain yield decreased by 37%. A reduction in MME uncertainty range by 27% increased MME prediction skills by 47%. Results suggest that the mean level of variation observed in field experiments and used as a benchmark can be reached with half the number of models in the MME. Improving crop models is therefore important to increase the certainty of model-based impact assessments and allow more practical, i.e. smaller MMEs to be used effectively. [less ▲]

Interacting soil organisms support biological processes that participate in soil functions, organic matter decomposition, and nutrient cycling. Earthworms and microorganisms play a range of beneficial roles in agricultural systems, including increased organic matter mineralization, nutrient cycling, and soil structure stabilization. The following aspects of crop residue management effects are examined in this paper: (i) earthworm composition and structure; (ii) soil microbial communities; and (iii) phosphorus (P) and nitrogen (N) element availability and distribution in the soil profile. Conventional tillage (ploughing) is often reported to generate decreased soil organism abundance and diversity, primarily earthworms and microorganisms, as well as a uniform distribution of the nutrients P and N within the ploughed soil horizon. Soil residue incorporation of mineral particles can maintain P and N levels, however returning soil also increases aeration and the activation of microbial activity. Hence, comparisons of tillage effects on soil biological functioning and nutrient cycling remain unclear. This review highlights the challenges in establishing definitive evidence regarding the effects of crop residue management on soil organisms and nutrient dynamics. The studies examined reported variability in soil and climate, and the complexity of soil processes contributed to the absence of clear findings. Further research is required under temperate climate conditions. [less ▲]

This study assesses the impact of supplemental irrigation from small man-made basins on cereal production in climate variability and change context marked by dry spells in the Sahelian zone of Burkina Faso. After two years, the experiments showed that this innovation in family farms increases maize yield and allows growing a second crop with the surplus of water available in the basin. At the end of the 2012-2013 campaign, the average maize yield was estimated 2.5 t/ha on experimental plots (EP) and 1.7 t/ha on control plots (CP). The average yield of the 2013-2014 campaign was evaluated as 3.3 T/ha and 0.9 t/ha for EP and CP respectively. Increase in yield is 0.8 t/ha for the 2012-2013 campaign and 2.4 t/ha during 2013-2014. It appears as well as the yield obtained on EP in 2012-2013 and 2013-2014 for bridging cereal need of 2 and 6 additional persons respectively in agricultural households compared to the CP. The review of the Net present value, Internal rate of return and the Net benefits increase ratio show that the profitability to practice supplemental irrigation depends on the types of basins.

Droughts and water shortage are generally accepted to be one of the most critical problems faced by worldwide agriculture, and it is so especially in China where agricultural production and prosperity are largely dependent on the timely, adequate and proper distribution of rainfall. The analysis of water productivity is becoming very critical in light of population growth, food security and increasing pressure on water resources. However, there is limited understanding of the spatio-temporal variation of crop water productivity (CWP) from the rotation system and its key influencing factors in Huang-Huai-Hai Plain (3H Plain) in which there is an over-exploitation of groundwater region and where future warmer and drought conditions will intensify crop water demand. As the largest water user, agricultural sector is facing a challenge to produce more crops with less water. Consequently, 3H Plain faced the double threat of both making contributions of high and stable yield to government and improving CWP of winter wheat through reducing water consumption. The overall ambition of this thesis was to investigate to what extent the grain yield and crop water productivity for winter wheat can respond to climate change and drought across the 3H Plain. In our study, a combined dataset composed of a historical 54-year time series and the RCP 8.5 scenario from 40 meteorological stations was provided by the China Meteorological Administration. Among these 40 stations we selected 12 stations with more detailed information available. The minimal data sets required for model operation include daily climatic variables, soil information and management information collected from the China Soil Scientific Database. Finally, we also used satellite data to estimate water productivity mainly involved in MODIS products including MOD11A1 (land surface temperature/surface emissivity), MOD13A2 (NDVI) and MCD43B3 (surface albedo). We used SPEI-PM method, DSSAT-CERES-Wheat model and SEBAL model to explore the characteristics in grain yield and crop water productivity for winter wheat in response to climate change and drought associated with their improvements across the 3H Plain. Our work demonstrated the investigation that an increase of ET0 was predicted leading to subsequent drought rise in frequency, duration, severity and intensity under the RCP 8.5 scenario. The cumulative probability of the simulated yield reduction was detected to be higher during jointing to heading stage in northern than southern region due to water stress and changes in the management inputs. The lower CWP was mainly situated in the low plain-hydropenia irrigable land and dry land (zone2) and the hill-wet hot paddy field (zone6), which suggests that it is an important issue and opportunity for improving agricultural water management in the water-scarce 3H Plain. The spatial increase of yield principally controlled increase of water productivity in north agricultural sub-regions and the spatial increase of water productivity was more governed by increment of yield than the reduction of ETa in other agricultural sub-regions. It will be adopted to develop feasible straw mulching, regulated deficit irrigation, and soil water storage and preservation to reduce pressure on groundwater over-exploitation, especially for winter wheat in the 3H Plain. In our work, major agronomic consequences have been drawn regarding the reform of the common agricultural policy in Huang-Huai-Hai Plain, China. Researchers are encouraged to further investigations into how to implement these practices with emphasis of improving the sustainability of these agro-ecosystems. [less ▲]
