Plant genetic resources can be conserved both in-situ and ex-situ. Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions. 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. function shs_animate(){ 0000018788 00000 n 0000003107 00000 n 0000008200 00000 n 0000006974 00000 n %PDF-1.3 %���� } trailer << /Size 100 /Info 60 0 R /Root 62 0 R /Prev 185313 /ID[] >> startxref 0 %%EOF 62 0 obj << /Type /Catalog /Pages 58 0 R /PageLabels 56 0 R >> endobj 98 0 obj << /S 123 /L 209 /Filter /FlateDecode /Length 99 0 R >> stream 0000005833 00000 n Gene banks store cells from various species in liquid nitrogen that can later be used to preserve the gene pool of an endangered species. Therefore, poor gene flow among the populations in M. subcordatum could be due to genetic barriers caused by the tributaries of river Tambraparani. 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. It is generally recognized that plant genetic diversity changes in time and space. This loss of genetic diversity in plant crops and animal breed is dangerous because it makes our food supply more vulnerable. The natural world has several ways of preserving or increasing genetic diversity. The report notes that genetic information held in certain crop varieties is crucial to the development of heat, drought, salinity, pest and diseases-resistant, fast-growing, high-yielding new varieties that are necessary to reduce food insecurity in the face of climate change. jQuery('#shs_slider_ul:not(:animated)').animate({'left' : '-300px'},1000,function(){}); Guidance is particularly needed on how many living plants are necessary to conserve a threshold level of genetic diversity in ex situ collections. Any human activity that affects the delicate relationships between species and habitats will impoverish our quality of life and reduce the number of resources available to us. FAO believes that increasing the sustainable use of plant diversity could be the main key for addressing risks to genetic resources for agriculture. jQuery('#shs_slider_ul:not(:animated)').animate({'left' : left_indent},1000, FAO is particularly concerned that such trend threatens the world’s food security and efforts must be made to conserve the plant diversity that are genetically related to the crops that we grow and eat. 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. jQuery('#shs_slider_ul').css({'left':'-300px'}); Genetic diversity is important for two reasons. Our plant conservation efforts. 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. We need to broaden our skills and knowledge to better use PGR and biodiversity of food crops for the benefit of society. FAO, established by the United Nations, is concerned that if the current trend persist, as many as half of all plant species could face extinction. var shs=setInterval(function(){ shs_animate(); },7000); By JAMES LARAKI THE loss of plant genetic diversity is considered one of today’s most serious environmental concerns by the Food and Agricultural Organisation (FAO). Genetic diversity is important to a species’ fitness, long-term viability, and ability to adapt to changing environmental conditions.

It is generally recognized that plant genetic diversity changes in time and space. 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. Ocean viruses, which infect the plankton, carry genes of other organisms in addition to their own. T he plant genetic diversity used in agriculture—the crops that feed us and their wild relatives—is being lost at an alarming rate. The National, Tuesday 04th September 2012. Growing concerns for the loss of plant genetic diversity and species’ extinctions, as well as advancing know-how to make successful conservation collections, motivates CPC Network scientists to collect seeds from wild populations and bank them.. This is part of the institute’s efforts towards building capacity and is being done in partnership with the Solomon Islands ministry of agriculture and livestock and the Vanuatu agricultural research and technical centre. 0000012216 00000 n One in five plant species are at risk of extinction worldwide. 1 The Need to Conserve Livestock Genetic Resources Selected varieties of plants and animals form the foundation of agriculture. The areas covered in these series are focused on PGR collection and maintenance, characterisation and evaluation, conservation, screening and evaluation, pre-breeding techniques and breeding and utilisations. Coupled with the loss of biodiversity is the lack of knowledge on how to collect, maintain and utilise the plant genetic resources. jQuery('#shs_slider_ul').css({'left':'-300px'}); NARI is conducting this training series with the aim to improve the human resource capacity in PGR conservation and utilisation in research and development institutions in the region. jQuery(document).ready(function() { In their fields and in the nearby wild areas, there is a huge diversity of plants, which continue to evolve and adapt to changing conditions and so can be used to provide useful genes for new crops. Smallholder farmers can use diversity of crops as a resource to adapt their crops to environmental changes. The participants are also expected to become trainers of others in their respective organisations and countries. 0000005855 00000 n The western Pacific region, including PNG, is rich in plant genetic diversity and home to many food crops. This loss of genetic diversity in plant crops and animal breed is dangerous because it makes our food supply more vulnerable. shs_animate_next(); Just nine crops (wheat, rice, maize, barley, sorghum/millet, potato, sweet potato/yam, sugar cane and soybean) account for over 75 percent of the plant kingdom's contribution to human dietary energy. 0000012237 00000 n New varieties of plants can be grown by cross-breeding different genetic variants and produce plants with desirable traits like disease resistance, increased tolerance to stress.
