While the adoption of irrigation technology that confers water savings has improved water-use efficiency at the vineyard level, further gains can be made by planting inherently efficient varieties (Condon et al., 2004).
Current understanding of complex genetic control of N and P utilisation is being converged towards precision breeding such as marker assisted breeding for nutrient efficient varieties.
Genomic technology can overcome these limitations providing new tools, for example, to produce more efficient varieties and rootstocks and to identify new genes, alleles or genotypes of agronomic relevance.
Amy Hardberger, of the Environmental Defence Fund in Austin, suggests that asking people to stop watering their lawns in the blistering afternoon sun is like asking them to swap their light bulbs for the energy-efficient variety: not a cure-all, but a valuable conceptual lesson.
And at the zoo, they're all on, and most of them these days are of the more efficient LED variety.
Other conspirators include "Europeans [who] now see global warming as a means of hampering U.S. economic competitiveness" and yes, even Wal-Mart, the conservative stalwart, which is scheming to sell compact fluorescent bulbs rather than the cheaper but less efficient incandescent variety.
Therefore, systematic approaches need to be made to use soil P and fertilizer P sustainably and efficiently, including development of P-efficient crop varieties (Lynch, 2011).
The Green Revolution was an intensifying of input-based production characterized by the use of high-yielding and fertilizer-efficient new varieties of seed (rice and wheat).
Molecular breeding therefore provides an exciting opportunity to use this gene pool effectively for the development of well-adapted and nutrient-efficient rice varieties.
The government has worked to make the power system more efficient through a variety of privatization measures, handing broad responsibility to the National Grid Corporation of the Philippines, created in 2008.
With effective and efficient treatment, a variety of waters with impaired quality can potentially be beneficially used in many applications.
