Dear Mr. Henk,
Several modeling studies project, by the end of the twenty first century, a decrease of grain crop (maize, rice and wheat) yields/productivity due to the increase of frequency, magnitude, and duration of climate-related stressors, such as heat-waves and tropical cyclones. Indeed, some observational studies had demonstrated a similar correlation during the recent past. During the European heat wave of 2003, for instance, temperatures increased by 6?C above long-term means and precipitation deficits increased by 300 mm. Consequently, the heat-wave reduced yields of maize/corn (Zea mays). When compared to the 2002 harvests, maize yields decreased in 2003 by 36% and 30% in Italy and France, respectively. To what extent will European farmers be able to adapt their high-input cropping systems to climate change and variability by the year 2100?
Francis Bagambilana (from Tanzania (United Republic of))
Dear Francis, you are certainly correct that this is major issue. Not only in Europe,also in North America, parts of Asia and South America this will become a major issues. The first step is of course reducing GHG and climate change. Further we will need resilient agricultural systems, which make more effecitve use of ecosystem services (thus lower pesticide use) and with lower nutriënt losses (thus lower need for input of fertilizers). I hope that this answers your questions.
Kind regards Henk

Dear M. Westhoek,
I am an innovative project holder in tne diary sector showing that huge quantities of water may be saved compared to conventional agriculture. In this special climate change context especially in South Mediterannean countries while we still need more milk and meat production increase, shouldn't we base that increase on other crops than corn, lucerne, and soja, knowing that natural pastures are almost inexistant in our arid climate countries.
That's my project's focus.
Dear M. Westhoek,
I'd be very pleased if you could introduce my project toward FrieslandCampina decision makers if they can be our idustrial partners and toward the Wagheningen University as forage will be produced in hydroponic greenhouses.
I'd be very pleased if you could give me your feedback so we may study how we can make this proof of concept.

Dear Nour Iraki,

I understand your idea, and indeed it will be difficult to base on natural pastures only.
What I know is that the production of bulk products such as forage will be very expensive if you will do so in hydroponic greenhouses. In The Netherlands (my home country) we grow only high value crops in greenhouses, such as certain vegetables (but certainly not all).
I am not sure whether FrieslandCampina is active in Morocco, but I will try to contact them once I am home.

I am a master's student in natural resources management at the Cpperbelt University, Zambia. I am carrying out a research on phytoremediation of mine tailings hee in Zambia. Is there a workshop, seminar, conference or short training that you would recommend to attend so as to gain know how on phytoremediation field? Thank you.

Dear Elijah Mwangi,

Not that I am aware of, I hope you can find something because it sounds very interesting and relevant.

kind regards, Henk Westhoek

Dear Kapil Awtani,

These are quite specific questions, and I am sorry I cannot answer these in detail.
Please look on the web whether you can find some guidance.
