An Innovation System Perspective on Adaptation Strategies to Climate Variability and Water Management in India

Government policies play a critical role in influencing market conditions, institutions and overall agricultural productivity. The thesis therefore looks into the history of agriculture development in India. Taking a political economy perspective, the historical account looks at significant institutional and technological innovations carried out in pre- independent and post independent India. It further focuses on the Green Revolution in Asia, as forty years after; the agricultural community still faces the task of addressing recurrent issue of food security amidst emerging challenges, such as climate change. It examines the Green Revolution that took place in India during the late 1960s and 70s in a historical perspective, identifying two factors of institutional change and political leadership. Climate change in agriculture development has become a major concern to farmers, researchers and policy makers alike. However, there is little knowledge on the farmers’ perception to climate change and to the extent they coincide with actual climatic data. Using a qualitative approach,it looks into the perceptions of the farmers in four villages in the states of Maharashtra and Andhra Pradesh. While exploring the adaptation strategies, the chapter looks into the dynamics of who can afford a particular technology and who cannot and what leads to a particular adaptation decision thus determining the adaptive capacity in water management. The final section looks into the devolution of authority for natural resource management to local user groups through the Water Users’ Associations as an important approach to overcome the long-standing challenges of centralized state bureaucracies in India. It addresses the knowledge gap of why some local user groups are able to overcome governance challenges such as elite capture, while others-that work under the design principles developed by Elinor Ostrom. It draws conclusions on how local leadership, can be promoted to facilitate participatory irrigation management.

La cooperazione dell'UE nella creazione di uno spazio sicuro nella globalizzazione come possibile modello per la regione dell'Asia Centrale

Gli ultimi anni hanno visto importanti cambiamenti positivi nella cooperazione interstatale in Asia centrale. Crescenti minacce come il terrorismo internazionale, l'estremismo religioso e politico, il traffico di droga, ecc, causati dagli interessi geopolitici e geo-economici delle potenze mondiali, hanno contribuito alla formazione di una politica estera più coordinata e coerente degli Stati della regione. Questo processo si manifesta nella partecipazione attiva dell’istituzionalizzazione della Shanghai Organizzazione del Commonwealth (SOC), Conferenza sulle misure di costruzione d’interazione e fiducia in Asia (CICA) e Organizzazione del Trattato di Sicurezza Collettiva (CSTO). Problemi moderni di sicurezza in Asia centrale dovrebbero essere risolti in dei nuovi modi, non convenzionali. Le nuove minacce alla sicurezza richiedono modi non standard per risolvere il problema. Considerate le differenze fondamentali dell'Unione europea e degli Stati dell'Asia centrale nei valori e dal punto di vista in materia di sicurezza. I paesi dell'Asia centrale non sono pronti per l'integrazione politica. Nonostante questo, nell’Asia centrale sono state adottate misure per contrastare le minacce non convenzionali. L’esperienza europea di unire gli sforzi della regione per garantire la sicurezza interna, può essere utilizzata dai paesi dell'Asia centrale, soprattutto, in primo luogo sulla formazione del quadro istituzionale e giuridico per la cooperazione operativa delle forze dell'ordine per le seguenti aree: • prevenzione del traffico di droga attraverso gli Stati dell'Asia centrale; • lotta contro nuove forme di terrorismo ed estremismo; • limitare la dimensione della migrazione clandestina; • migliorare la protezione giuridica dei cittadini. Fino a poco tempo fa, questi temi hanno ricevuto poca attenzione, sia nella teoria sia nella pratica, poiché i problemi di sicurezza della società erano principalmente ridotti per evitare il pericolo di guerra.

Landslide susceptibility in the Belt and Road Initiative

The Belt and Road Initiative (BRI) is a project launched by the Chinese Government whose main goal is to connect more than 65 countries in Asia, Europe, Africa and Oceania developing infrastructures and facilities. To support the prevention or mitigation of landslide hazards, which may affect the mainland infrastructures of BRI, a landslide susceptibility analysis in the countries involved has been carried out. Due to the large study area, the analysis has been carried out using a multi-scale approach which consists of mapping susceptibility firstly at continental scale, and then at national scale. The study area selected for the continental assessment is the south-Asia, where a pixel-based landslide susceptibility map has been carried out using the Weight of Evidence method and validated by Receiving Operating Characteristic (ROC) curves. Then, we selected the regions of west Tajikistan and north-east India to be investigated at national scale. Data scarcity is a common condition for many countries involved into the Initiative. Therefore in addition to the landslide susceptibility assessment of west Tajikistan, which has been conducted using a Generalized Additive Model and validated by ROC curves, we have examined, in the same study area, the effect of incomplete landslide dataset on the prediction capacity of statistical models. The entire PhD research activity has been conducted using only open data and open-source software. In this context, to support the analysis of the last years an open-source plugin for QGIS has been implemented. The SZ-tool allows the user to make susceptibility assessments from the data preprocessing, susceptibility mapping, to the final classification. All the output data of the analysis conducted are freely available and downloadable. This text describes the research activity of the last three years. Each chapter reports the text of the articles published in international scientific journal during the PhD.

Resistance and opposition to the Macedonian kingship in the ancient Iranian world

This thesis deals with the criticism of Macedonian kingship in the ancient Iranian world. The question of indigenous opposition and resistance to the Greeks and Macedonians has been little addressed by ancient historians. The study therefore adopts a different, interdisciplinary perspective and seeks to understand where the utterly negative portrayal of Alexander and the Macedonians found in most Iranian sources stems from. The first part deals with the subject by first examining the acts of violence committed by Alexander and his men against the Iranians during the expedition to Asia that might have led to such a portrayal in the Iranian sources. I have focused on looting, massacres and insults to deities, such as the looting of temples or the destruction of many settlements in ancient Iran handed down in classical sources. To this end, an important part was devoted to the analysis of archaeological sources, especially the signs of destruction in areas such as Persia and Sogdiana. In the second part, the image of Alexander and his successors, although mentioned much less frequently, as it appears in pre-Islamic Iranian literature, is analysed in detail, focusing on the faults and cruelties attributed to them against the Iranians, but especially against their religion. These are mostly Zoroastrian religious sources, whose clergy preserved a demonic image of the Macedonian kings. In the third and final part, further examples of offences committed by the Diadochi and Seleucids against the Iranians in the classical tradition are collected. At the same time, it is examined how the Hellenistic rulers of Iranian origin, e.g. the Arsacids and the Orontids, opposed not only militarily but also ideologically the Macedonian tradition represented by the kingdoms of Macedonian descent and chose a pro-Iranian tradition that was clearly different from the Greco-Roman one.

Studio della Peste dei Piccoli Ruminanti nei territori saharawi

La Peste dei Piccoli Ruminanti (PPR) è una patologia virale ed acuta che colpisce i piccoli ruminanti, diffusa in Africa Sub-Sahariana, in Medio Oriente ed in Asia Meridionale. Questo lavoro si propone di effettuare il primo studio epidemiologico sulla PPR nella Repubblica Araba Saharawi Democratica (RASD), che comprende i Campi Profughi Saharawi, in territorio algerino, ed i “Territori Liberati” del Sahara Occidentale, valutando la potenziale presenza, prevalenza e distribuzione del virus della PPR in questi territori. Lo studio si è basato su una metodica di campionamento “a cluster” secondo la tecnica “a due stadi”. Sono stati individuati 23 siti di campionamento dai quali sono stati raccolti un totale di 976 campioni di siero prelevati da pecore, capre e cammelli. I campioni sono stati prelevati in Marzo ed Aprile 2008. I risultati dei test Competitive-Elisa hanno evidenziato una sieroprevalenza nel 28,26% degli animali testati, benché durante la raccolta dei campioni nessun animale abbia presentato sintomi clinici riferibili alla PPR. Tra Gennaio e Maggio 2010, in seguito ad episodi di aumentata mortalità nella popolazione ovi-caprina presente nei Campi Profughi, le autorità veterinarie locali sospettarono un outbreak di PPR. Tra Maggio ed Ottobre 2010 è stato sviluppato un outbreak investigation nei Campi Profughi Saharawi con lo scopo di confermare la circolazione del PPRV. I risultati di laboratorio hanno confermato la presenza del virus nel 33,33% dei campioni. Il sequenziamento del genoma virale ha rivelato che il virus apparteneva al Lignaggio 4 e le analisi filogenetiche hanno indicato una stretta relazione (99.3%) con il PPRV isolato durante l'epidemia di PPR in Marocco del 2008.

Identification and genetic diversity in phytoplasmas associated with diseases of cassava and other agronomic relevant crops in south-east Asia and Latin America

Identification and genetic diversity of phytoplasmas infecting tropical plant species, selected among those most agronomically relevant in South-east Asia and Latin America were studied. Correlation between evolutionary divergence of relevant phytoplasma strains and their geographic distribution by comparison on homologous genes of phytoplasma strains detected in the same or related plant species in other geographical areas worldwide was achieved. Molecular diversity was studied on genes coding ribosomal proteins, groEL, tuf and amp besides phytoplasma 16S rRNA. Selected samples infected by phytoplasmas belonging to diverse ribosomal groups were also studied by in silico RFLP followed by phylogenetic analyses. Moreover a partial genome annotation of a ‘Ca. P. brasiliense’ strain was done towards future application for epidemiological studies. Phytoplasma presence in cassava showing frog skin (CFSD) and witches’ broom (CWB) diseases in Costa Rica - Paraguay and in Vietnam – Thailand, respectively, was evaluated. In both cases, the diseases were associated with phytoplasmas related to aster yellows, apple proliferation and “stolbur” groups, while only phytoplasma related to X-disease group in CFSD, and to hibiscus witches’ broom, elm yellows and clover proliferation groups in CWB. Variability was found among strains belonging to the same ribosomal group but having different geographic origin and associated with different disease. Additionally, a dodder transmission assay to elucidate the role of phytoplasmas in CWB disease was carried out, and resulted in typical phytoplasma symptoms in periwinkle plants associated with the presence of aster yellows-related strains. Lethal wilt disease, a severe disease of oil palm in Colombia that is spreading throughout South America was also studied. Phytoplasmas were detected in symptomatic oil palm and identified as ‘Ca. P. asteris’, ribosomal subgroup 16SrI-B, and were distinguished from other aster yellows phytoplasmas used as reference strains; in particular, from an aster yellows strain infecting corn in the same country.
