The Water Suitcase of Migrants: Assessing Virtual Water Fluxes Associated to ...
The Water Suitcase of Migrants: Assessing Virtual Water Fluxes Associated to ...University of Salerno
Disentangling the relations between human migrations and water resources is relevant for food security and trade policy in water-scarce countries. It is commonly believed that human migrations are beneficial to the water endowments of origin countries for reducing the pressure on local resources. We show here that such belief is over-simplistic. We reframe the problem by considering the international food trade and the corresponding virtual water fluxes, which quantify the water used for the production of traded agricultural commodities. By means of robust analytical tools, we show that migrants strengthen the commercial links between countries, triggering trade fluxes caused by food consumption habits persisting after migration. Thus migrants significantly increase the virtual water fluxes and the use of water in the countries of origin. The flux ascribable to each migrant, i.e. the “water suitcase”, is found to have increased from 321 m3/y in 1990 to 1367 m3/y in 2010. A comparison with the water footprint of individuals shows that where the water suitcase exceeds the water footprint of inhabitants, migrations turn out to be detrimental to the water endowments of origin countries, challenging the common perception that migrations tend to relieve the pressure on the local (water) resources of origin countries.The Global Virtual Water Network
''The global virtual water network'' is a FIRB project funded by MIUR which aims at studying the main characteristics and implications of the virtual water flows associated to the international trade of food.
The project has the following main goals:
understanding the global dynamics of virtual water flows;
investigating the international water (and food) trade network;
evaluating impacts and feedbacks for food security;
assessing the vulnerability of the system to crises.
We aim at investigating the complex relationships between climatic, agronomic and socio-economic factors and how they shape the evolution of the worldwide trade of virtual water.

PER IL RITORNO AL TERRITORIO, BENE COMUNE
La società dei territorialisti e delle territorialiste ai candidati delle elezioni del 24 febbraio 2013: un appello http://www.societadeiterritorialisti.it
La riflessione sulle prime tre declinazioni del ritorno al territorio richiede di focalizzare la
sfida su nuove forme di produzione della ricchezza, che sappiano trarre dalla ricostruzione
dei beni patrimoniali locali le basi materiali della produzione di valore aggiunto territoriale.
Nuove forme di intrapresa economica, adatte a promuovere i sistemi locali territoriali e
forme di scambio solidali, a mettere in valore e a gestire beni comuni territoriali, ambientali e
paesaggistici, richiedono ruoli nuovi del governo del territorio nella ricerca di diversi sistemi
socioeconomici, nella consapevolezza che investire in territorio, ambiente e paesaggio può
produrre nuova ricchezza durevole, ovvero nuove forme di reddito, di attività produttive,
di servizi ecosistemici e sociali.

Reasons for Using Employee Time Tracking
Running a business with lots of employees can be very difficult to manage at times. Often, it can be difficult to stressful and confusing. There are many things going on all at once that managing them efficiently can be true bother. When it comes to employees, though, there exists many ways to ensure that the whole ordeal is managed in an efficient way.

Top 8 westjet pilot interview questions answers
This document provides sample answers to common interview questions for the role of Westjet pilot. It discusses answering questions about proficiency in multiple languages, handling multiple simultaneous responsibilities during flight, behaving during an emergency, modifying flight courses, career goals, strengths, knowledge of the organization, and ways to improve aviation knowledge. The document emphasizes preparing examples to demonstrate skills, relating answers to the job requirements, and showing continuous learning and self-improvement.
3D printing for rapid prototyping
3D printing, also known as additive manufacturing, is a process where 3D objects are created by laying down successive layers of material until an entire object is formed. The earliest 3D printing technologies emerged in the late 1980s as a way to rapidly prototype products. There are several types of 3D printers that use different processes like stereolithography, digital light processing, and fused deposition modeling. 3D printing provides significant advantages over traditional manufacturing by reducing costs through less wasted materials, faster production times, and enabling new manufacturing strategies like highly customized medical devices.

La Unión Europea ha acordado un paquete de sanciones contra Rusia por su invasión de Ucrania. Las sanciones incluyen restricciones a los bancos rusos, la prohibición de la venta de aviones y equipos a Rusia, y sanciones contra funcionarios rusos. Los líderes de la UE esperan que las sanciones aumenten la presión económica sobre Rusia y la disuadan de continuar su agresión contra Ucrania.
El derecho a la libertad de conciencia
El documento resume el derecho a la libertad de conciencia y la objeción de conciencia según la Constitución colombiana y la jurisprudencia. Explica que la libertad de conciencia protege 3 garantías: no ser molestado por creencias, no ser obligado a revelar creencias, y no ser obligado a actuar contra la conciencia. Luego resume distintos casos donde se ha reconocido la objeción de conciencia en ámbitos como educación, salud, laboral y servicio militar.
Formulación de una pregunta
El documento enfatiza la importancia de hacer preguntas en clase para mejorar el aprendizaje. Los estudiantes deben prepararse antes de clase para poder resolver dudas y aprender más. No basta con hacer preguntas, estas deben ser claras, relevantes e investigativas. Una pregunta de investigación debe incluir la pregunta base, unidad de análisis, variables y dimensiones temporal y espacial.

Scopo impronta ecologica
- 1. L’ impronta ecologica ha lo scopo di sensibilizzare i cittadini verso una realtà futura in cui la domanda umana di risorse naturali sia monitorata costantemente, per poter ottenere nuove soluzioni ed accendere un dialogo sui limiti ecologici e il sovra utilizzo delle risorse naturali. Lo scopo dell’impronta ecologica è quindi, di provare a costruire un futuro eco sostenibile. L’impronta ecologica ha anche lo scopo di misurare quanto territorio biologicamente produttivo, viene impiegato da un individuo, una famiglia , una città, una regione, un paese e persino dell’intera umanità per produrre le risorse che consuma e per assorbire i rifiuti che genera.
