Providing extension and advisory services is expensive. There are salaries to be paid, transporta­tion and operational funds to be provided, buildings to be rented or built, demonstration plots to maintain, and continued education to be offered to the extension staff. And then there is the need to continually invest in an overall functioning agricultural innovation system with strong research and teaching institutions, enabling policies, as well as to make capital investments in rural infrastructure that will not only benefit the farming population.

Recent studies have shown that modern breeding for high yield, visual appearance and long shelf life led to an unintentional decline in taste and the content of essential nutrients in vegetables. AVRDC – The World Vegetable Center is studying whether traditional vegetables are more nutritious than modern varieties and whether early growth stages of these vegetables offer consumers a higher content of phytonutrients.

Twenty-seven nations are classified as ‘water scarce’, a further 16 as ‘water stressed’. This situation, coupled with the fact that many surface and groundwater systems are shared between two or more states, has led governments to develop sustainable water management strategies. This implies a real commitment by all water users – households, farmers, and industrialists – to use available supplies in ways that reap sustainable and equitable benefits for all.
