Research overview

par FADER Marianela

My current research includes five areas :

1. Irrigation water requirements under climate change in the Mediterranean area and the possibility of supplying the energy needed by irrigation systems with photovoltaic panels. This is an ongoing 2 year-project financed by the Laboratory of Excellence OT-Med. See bellow, under « Research » for more details.

2. Global land use change, land use transitions, agricultural practices and their relation with climate change. These topics were assessed in my PhD work and will be part of a 2-year project starting on July 2015 in the framework on an EU financed project (LUC4C).

3. Resilience of the global food trade systems, potential disruptive shocks in the system and the relation to biophysical capacities of countries (yield gap closure, water and land availability). This is part of an ongoing project funded by SESYNC and in cooperation with a small group of scientists of all around the world.

4. Consequences of climate change for the agriculture of the MENA region. This is a recent consultancy project funded by the world bank and published as the report « Turn Down the Heat ».

5. Spatial decoupling of production and consumption areas, virtual water and water footprints. These topics were assessed in my PhD work (see main article here and power point presentation of the project here), and are also part of an ongoing cooperation with Emma Johansson, PhD student at the University of Lund.

See more details in the sections bellow. There, you will find, among others, presentations ready to download under « Presentations & Teaching ».

Tools : For all my research areas I combine data analysis and mechanistic modelling. On the later part I work with the vegetation, hydrology and agro-ecosystem model LPJmL. See here the homepage of the model and here a short presentation about the functionalities included.

Keywords :






























OT-Med Project : Solar energy for irrigation : mitigation and adaptation option for the Mediterranean ?

The countries of the Mediterranean region cover 8,760 million km2 and hold 430 million people (FAO 2003). These countries represent 7% of the world population, but they account for 25% of world food imports (Mediterra, 2008). Roughly speaking, around 22 % of the population of these countries works in agriculture, cultivating a total of 130 million ha (Nunes Correia 1999) and producing a gross value of 225 billion US$ per year (FAO 2012). The Mediterranean is characterized by natural climate variability, and spatially and temporally variable water scarcity. Currently, 108 million inhabitants, mainly in the Southern Mediterranean, have water availability of less than 1000 m3 yr-1 (Hallegatte 2010) and most Mediterranean areas experience water deficit (Nunes Correia 1999). Agriculture is the main user of this scarce resource : only about 15 % of cultivated area is irrigated but it accounts in 15 out of 19 countries for more than 50 % of the total water withdrawal (FAO 2012 ; Eulisse et al. 2009 ; Nunes Correia 1999).

75-95% of the energy supply in the Mediterranean is produced with fossil fuels. This situation makes the Mediterranean vulnerable to future oil price shocks and reveal a high dependence on fossil fuel reserves and on the future geopolitical strategies of the oil exporters (Hallegatte 2010). But more importantly, it leaves the door open for a positive feedback : climate change may lead to higher irrigation water requirements, which in turn would need more energy and would lead, at the end, to more fossil fuel burning and more climate change. This project aims to evaluate the possibility of breaking this positive feedback by testing the potentials of solar energy to drive future irrigation. The project is structured in the following research questions :

1. Does climate change increase irrigation water requirements in the Mediterranean area ?

2. How much energy demand increase can be expected due to higher irrigation water requirements ?

3. How much money and roof surface would be needed to drive irrigation fully with solar energy ?

4. Can a switch of irrigation systems reduce irrigation water requirements and/or energy requirements of irrigation today and in future ?

This project makes use of geographical and statistical as well as modelling experiments. In order to account for the interlinkages between land use and the water balance, an ecosystem modelling approach is needed. LPJmL, a process-based, biogeochemical, dynamic global vegetation and hydrology model, is therefore being used and further developed to tackle these questions.
