"Hãy vươn tới những vì sao. Cho dù không chạm được vào nó, nhưng nếu cố gắng hết sức, ít ra, chúng ta cũng chạm được những hạt bụi của ngôi sao" (Reach for the stars. Although you will never touch them, if you reach hard enough, you will find that you get a little star dust on you in the process).

FOOD CROPS. "Đời người tối thiểu phải ăn, kế đến là học tập, công việc, nhà ở, quần áo và chăm sóc sức khỏe. Quanh ta còn nhiều mảnh đời bất hạnh. Hiểm họa nghèo đói vẫn bùng phát bất cứ lúc nào. Hãy luôn nhớ điều đó." Lời của Thầy Norman Bourlaug và di sản của Người về cuộc cách mạng xanh mãi mãi là niềm tin và nổ lực của chúng ta !

GLOBAL CASSAVA PARTNERSHIPS GCP1

“Cassava : Meeting the Chalenges of
the New Millennium” July 21-25, 2008
IPBO – Ghent University – Belgium

Cassava is one of the major subsistence crops in the world. It feeds more than a billion people every day, through it is today exploited at about 15% of it current potential. Many factores account for this situation , most of them due to the fact that it is a vegetatively propagated crop, therefore associated with a lot of biotic constraints. However, it natural drought resistance and it semi-perennial botanical nature offer incomparable advantages for poor farmers. Expressing the full potential of cassava would turn this subsistence crop into an industrial one. This evolution already took place in several Asian coutries and South America, and in some rare places in Africa. It the largest number of people in developing countries use cassava as a crop to solve the food problem in the world and to change the economy of developing countries.

During the First Scientific meeting of the Global Cassava Partnership (GCP-1), we will review the status of knowledge about cassava, to show its potential and demonstrate the possibilities to unlock that potential !

The first day of the meeting, dubbed “Donor Day” is entirely dedicated to illustrate all the recent initiatives taken in cassava research and development, and to promote a discussion about the gaps in knowledge and funding.

During the week, 115 presentations by all the world most knowledgeable cassava experts, gathered in 13 concurrent sessions, intend to review all the recent advances made in cassava science and cassava improvement. Three days of poster sessions, with open 200 posters, will provide an opportunity to exchange, talk and argue about issues important for casava.

More importantly, the goal of this International Cassava Forum is to convince donors of the necessity to invest more , to strengthen the synergy in the cassava community, as well as to encourage more scientists to work with this very important crop, the third source of calories in the developing world, which feeds more than a billion people every day!

Cassava: A Gift to the World and a Challenge for Scientists

The Global Cassava Partnership, a network of scientists and developpers of cassava, aims to improve cassava by promoting the investment of science and technology worldwide. In the past decade the cassava research community has made impressive progress in tackling important production constraints in the areas of assembling large conlections of landraces and willspecies, breeding for pest and disease resistance and added value traits, development of low-cost rapid propagation systems, implementation of genomics tools for marker-assisted selectionand virus diagnostics, development of transgeniccassava for nutritions traits and for resistance to viruses, and the establishment of regional public and private sector partnership. Despit these improvements, yields in large parts of the cassava production areas are well below the potential of the germplasm developed. Limitations exist and are preventing the rapid formation of the next generationof cassava scientists on a large scale. Gaps still persist in the areas of technology transfer and in delivering added values for casava end users. The GCP has identified several opportunities and strategies to improve cassava production systems and they will be presented and discussed during the First Scientific meeting of the Global Cassava Partnership (GCP 1).
