This weblog documents the activities of Pacific Agricultural Genetic Resources Network (PAPGREN), along with other information on plant genetic resources (PGR) in the Pacific.
The myriad varieties found within cultivated plants are fundamental to the present and future productivity of agriculture. PAPGREN, which is coordinated by the Land Resources Division of the Secretariat of the Pacific Community (SPC), helps Pacific countries and territories to conserve their crop genetic diversity sustainably, with technical assistance from the Bioversity International (BI) and support from NZAID and ACIAR.
SPC also hosts the Centre of Pacific Crops and Trees (CEPaCT). The CEPaCT maintains regional in vitro collections of crops important to the Pacific and carries out research on tissue culture technology. The CEPaCT Adviser is Dr Mary Taylor (MaryT@spc.int), the CEPaCT Curator is Ms Valerie Tuia (ValerieT@spc.int).

Water implications of biofuel crops:
understanding tradeos and identifying options
From : IWMI
Biofuels are being touted as a solution to rising fuel prices, growing
energy demands, and the need to curb emissions of greenhouse
gases. Governments have good reasons for promoting biofuels.
Yet, a headlong rush into growing biofuel crops will bring its own
problems. Unless planned properly, biofuel crops are likely to
escalate competition for water, especially in areas where it is already
New research shows what options policymakers have for making
tradeos between biofuels and other uses of water. And, biofuel
crops that give ‘more crop per drop’ lessen the negative impacts and
boost the positive impacts.
• The development of biofuels will have an impact on water, food, energy and
the environment. How biofuels will affect these must be considered before
• Globally, there is enough water to produce both food and biofuel. But, in
countries where water is already scarce, like India and China, growing biofuel crops
will aggravate existing problems.
• Producing one liter of ethanol from sugarcane takes nearly 3,500 liters of
precious irrigation water in India, but just 90 liters of irrigation water in Brazil.
In China, it takes 2,400 liters of irrigation for maize to yield a liter of ethanol.
• Certain biofuel crops, such as jatropha trees and sweet sorghum, are less likely
to compete with food crops, use much less water, and have much less impact
on food production and the environment than others.
