If a population has < l N m it is more susceptible to genetic drift [ 42 ]. 0000011238 00000 n More could be lost forever unless we make special efforts not only to conserve … We investigated this question for 11 taxa across five genera. jQuery('#shs_slider_ul:not(:animated)').animate({'left' : left_indent},1000, 0000012216 00000 n The genetic diversity between and within plant species is being eroded each year. }). Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. Public institutions in the region are struggling on this front and efforts are urgently required as better use of genetic resources and biodiversity in food crops is essential for future food security. } The main reasons for conserving PGRFA are to ensure the future adaptability of cultivars and wild populations; to preserve data and traits that ensure sustainable agriculture; to promote the use of genetic resources in commerce and biotechnology; to conserve genetic diversity for cultural reasons. More vigorous varieties can better compete with weeds, reducing the need for applying herbicides. 0000006995 00000 n Smallholder farmers can use diversity of crops as a resource to adapt their crops to environmental changes. ical Diversity's recommendation to conserve 70% of genetic diversity in situ, as applied to rare alleles (~10 populations within each species' British range). The National, Tuesday 04th September 2012. 0000003107 00000 n Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. } 0000013203 00000 n conservation of the genetic diversity of crops, farm animals and trees. }); The continued lack of investment in agriculture, particularly in agricultural research over the years, has inevitably led to a shortage of qualified agricultural scientists including plant breeders in the region. }else{ jQuery('#shs_prev').click(function(){ The National | A Site By. 0000014807 00000 n This vital training series, through funding support from the EU ACP science and technology programme, would conclude at the end this year. �����)+�sx+�� R*+. However, maintaining genetic diversity is fundamental to food security and the provision of raw materials and it is best preserved within plants' natural habitats. 0000003443 00000 n
function shs_animate_next(){ This loss of genetic diversity in plant crops and animal breed is dangerous because it makes our food supply more vulnerable. In a report released recently, FAO warns that the loss of biodiversity will have a major impact on the ability of humankind to feed itself in the future, a situation it says is far more serious for inhabitants of developing countries. 0000014263 00000 n }); many reasons and they can be generally divided into two categories: the importance for ecosystems and for us var left_indent = parseInt(jQuery('#shs_slider_ul').css('left')) -item_width; To conserve the diversity found within species of cultivated plants, experts employ a strategy that combines ex situ conservation (storing diversity in genebanks) with in situ on-farm conservation in matching agro-ecosystems. } jQuery('#shs_slider_ul').css({'left':'-300px'}); 0000005833 00000 n Crop varieties that are resistant to pests and diseases can reduce the need to apply harmful pesticides. It works together with many different actors, such as breeders' organisations, networks of farmers, nature reserve Headquartered in Port Moresby, it has offices in Five (5)centres: Lae, Mount Hagen, Kokopo, Madang and Goroka. Hopefully, this training series would lay the foundation for us to work together to better conserve and utilise our biodiversity in our efforts towards reducing food insecurity in the region. 0000026613 00000 n Coupled with the loss of biodiversity is the lack of knowledge on how to collect, maintain and utilise the plant genetic resources. 0000008200 00000 n 0000008605 00000 n 0000010261 00000 n The natural world has several ways of preserving or increasing genetic diversity.

These wild relatives are presently threatened due to … Genetic diversity is important for two reasons. A selected number of research officers from partner and associate organisations from three countries have been put through these trainings and they are expected to play an important role in PGR conservation and utilisation.
