SESSION REPORT: Empowering rural women farmers with science—key to achieving food security

by Imelda V. Abano

In many parts of the world, it is the women who are responsible for food security, yet rural women farmers have little access to the benefits of research and innovation, said Jacqueline Ashby, a development sociologist and presently the Director of the Rural Innovation Institute at the Center for Tropical Agriculture in Colombia.

Professor Ashby said that 80 percent of the world’s 1.2 billion poor depend on agriculture for their survival and that rural women in developing countries play critical roles in guaranteeing food security and well-being for the entire community.

“Empowering women in most developing countries with science is key to achieving food security. We should communicate with them on what new plant varieties and new technology is being developed in order for them to improve their crop production,” Prof. Ashby said.

To help the rural women farmers in the developing countries, Prof. Ashby said that a new strategy is now being introduced — the participatory plant breeding (PPB).

PPB has been proposed as a way to address three problems of conventional plant breeding, namely its low effectiveness in marginal environments, the long time needed to develop a variety and the poor level of adoption, particularly in developing countries.

“Although it is difficult to introduce this new technology to women farmers in the developing countries we are determined to help them and so we partner with several organizations,” she said.

There are currently more than 80 programs worldwide using PPB in a number of different countries and crops. These countries are in Syria, Jordan, Eritrea and Egypt on barley, durum wheat, bread wheat, lentil and chickpea. The first varieties identified through PPB are already in farmers’ fields in Syria, Egypt, Eritrea and Yemen. Other countries such as Jordan and Eritrea are increasingly using PPB as their national breeding strategy.

SESSION REPORT: Is Australia running out of water?

By Imelda V. Abano

Water in Australia is emerging as a scarce commodity, fueled by population pressures, intensive irrigation and erratic weather patterns brought on by global warming.

Addressing science journalists at this session, climate change expert and author Tim Flannery said Australia’s drought was part of a global dry spell that threatened the planet’s future.

“While water shortage is a global phenomenon not just in Australia, the present drought had already put huge strain on river systems,” Flannery said adding that scientists have found a 10 to 15 percent decrease in rainfall over a 50 year period.

He warned that climate change will likely make things worse for water resource management in the Murray-Darling Basin. “The water that’s available for us to use is declining because of this warming trend.”

The Murray-Darling Basin is one of Australia’s foremost river systems responsible for irrigating the country’s crops. Australia is faced with water scarcity in the Murray-Darling Basin as a result of diverting large quantities of water for use in agriculture.

University of Adelaide Professor Mike Young said managing water supply is the biggest climate-change adaptation facing Australia.

“We need to build mechanisms that make people aware of the value of water and to cope with these changes,” Prof. Young said.

Prof. Young said there is an urgent need for “well-designed urban and rural water allocation: and trading systems that offer ways of ensuring that this system will be effective.

“We need to work-out with the government and talk to the community about this problem,” he said.

On the other hand, South Australia’s premier, Mike Rann said the issue of water has been paramount. He suggested a need to introduce legislation next year and adaptation with the prevailing issue of water in Australia.

“What we’re seeing with this drought is a frightening glimpse of the future with global warming,” Rann said.

SESSION REPORT: Climate change has far-reaching ramifications

by Piyaporn Wongruang

Former U.S. vice president Al Gore climbed over an elevator in one of the scenes featured in his recent Oscar Award documentary, “An Inconvenient Truth” to demonstrate how high the carbon dioxide greenhouse gas would rise in the sky, if the current emission course remained unchanged.

The elevator lifted him up to about three stories.

“An Inconvenient Truth” generated unprecedented discussion about climate issues worldwide. But some scientific reports about the subject are still very difficult to promote.

While people worldwide have been awed by the scenes of fierce storms, and such, the impact of climate change on people’s health apparently still lies in scientific reports, which are still in the hands of the scientists.

Dr. Tony McMichael, review editor for the Human Health chapter of the Intergovernmental Panel on Climate Change’s working group II said, the climate change focus is still very much on political and economic aspects.

“But we also know that public health is at risk,” he said.

An example of this was the heat waves in Europe during 2003, when death tolls increased to 900 when the temperature rose above the normal average daily temperature by about 12 degree Celsius.

Secondary impacts on people’s health, include increased injuries from extreme events, and the rise of infectious diseases and malnutrition, especially among the world’s
poor, Dr McMichael added.

Dr. Neville Nicholls, a lead author about climate change, said although reports could establish initial relationships between climate change and public
health, more knowledge is needed to help people better address these impacts and come up with adaptation measures.

He said people could start to act now. Take the case of Australia, which has attempted to mitigate impacts of heat-waves, which could become problematic to its senior citizens.

“We already know that people died because of them, and even though it may have not been from climate change, it’s still good to develop adaptation measures,” said Dr Nicholls, adding that adaptation could go in hand with mitigation.

Dr. Mongkol Na Songkla, Thailand’s Public Health Minister, said Thailand monitors the changing trends of some tropical diseases as a pro-active measure against climate change.

Recently, the ministry detected a surge in Malaria in the western part of the country, although its relation has not yet been linked to the change in weather patterns.

Apart from tropical diseases, Thais have also been encountering hotter and wetter weather, he said.

“The most significant thing for us to do is to equip our
people with adequate knowledge about climate change so that they can adapt themselves to the changing climate. Apart from this, our ministry will try to closely watch changes in disease trends, which may be related to the changing weather,” said Dr. Mongkol.

Health benefits will also help compensate the cost of mitigating climate change in the future.

Global concentration of greenhouse gases, mainly carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activity since 1750, and now far exceed pre-industrial values.

The increase of carbon dioxide is due primarily to fossil fuel use and land use change, while that of methane is primarily due to agriculture.

These have caused the total global temperature to increase up to 0.76 Celcius.

Eastern parts of North and South American northern Europe and northern and central Asia during 1900 to 2005 observed increased precipitation, while the Sahel, the Mediterranean, southern Africa, and parts of southern Asia observed drying condition.

More intense and longer droughts have been observed over wider areas since 1970s, particularly in the tropics and subtropics.

Both past and future human carbon dioxide emissions will continue to contribute to warming and sea level rise for more than a millennium.

SESSION REPORT: Climate Change in Ocean and how the media balance the reporting

By Xuxiuhua (from www.people.com.cn,China)

Climate change is now a hot topic to governments and scientists in developed and developing countries.

But it seems we pay too much attention to the land and not enough attention to the ocean.

At this session, Steve Rintoul, a scientist from CSIRO Marine & Southern Ocean Studies, says that since 1955, 84 percent of “global warming” is found in the ocean. So it stands to reason that the ocean, especially the ocean in polar regions, plays a critical role in climate change.

Polar regions can regulate the amount of CO2 — the main greenhouse gas which can cause global warming — being absorbed by the oceans. And new evidence shows that ice sheets are more dynamic than we thought before. Analysis of satellite data and tide-gauge observation indicates that the rate of sea-level rise has been increasing.

However there is another opinion. Some scientists consider that if you study the history of climate change criteria, the climate change we are enduring now is normal. The question is should the media present both sides of the argument to the public?

2nd SESSION REPORT: REPORTING CLIMATE CHANGE: THE DEVELOPING WORLD PERSPECTIVE

Presentation by Ochieng’ Ogodo

No doubt, communities need information on climate change. Good reporting on climate change is becoming increasingly important, especially for the developing world that has fragile economies and the vulnerable poor.

More and more, our lives are getting affected by the ever changing and unpredictable weather conditions. The developing world need to think about climate change, consider its impact on the environment, and deal with the problem. The community needs well informed science journalists who can report accurately and impartially on the impact of science on the society and across the world yet the subject is hardly covered by media in the South.

Throughout the 1990s, the media in the developing world was at the forefront of reporting on the devastation brought by the ‘El Niño’ rains, and bringing the issue of global climate change - and its impact on the local economy - into sharp focus.

The extensive coverage provided farmers and rural communities with a scientific explanation for the dramatic weather changes that they had been witnessing in recent years.

But while such high-profile occurrences captured the public imagination and generated intense debates on the impacts of environmental degradation on people’s day-to-day lives, the momentum generated was not sustained.

The topic of climate change that has captured the attention of the world for almost a decade 2000s, especially the developed nations, though they are culpable as major contributors to global warming, is not getting adequate attention in the media in the south.

The media has continued to focus on the ‘big’ stories such as deaths from drought, or the destruction caused by floods, with little information being provided on how to cope with the effects of climate-related changes.

Climate change is a relatively new concept within African media. Few journalists - or even editors, who are the gatekeepers of stories that go on air or into print - have a clear grasp of the science behind this phenomenon. On many occasions, science-oriented stories, as well as those covering forestry, agriculture, and climate change, get ‘spiked’. Publishers prefer stories about crime, violence and political scandal because this is what ‘sells.’

Yet above all, what farmers and rural communities require for mitigating and adapting to the effects of climate change, is access to information.

Farmers need to know whether the changing circumstances in which they grow their plants or raise their animals is merely a question of variability or a permanent change to weather patterns. Communities across the south also need channels through which they can share information on strategies that have worked well for them, and to adapt such techniques to their own circumstances, whenever possible.

Beyond sharing practical experiences, civil society organizations in the South need to discuss how best to exploit international support available through such instruments as the Kyoto Protocol’s Clean Development Mechanism (CDM), while continuing to debate amongst ourselves whether these approaches to emissions reductions are in their best interest.

The media - television, radio, print and online - naturally have a vital role to play in such debates, and yet there is a dearth of coverage of science issues in the developing world. A recent survey by the London-based NGO, Panos, of 47 journalists and from Jamaica, Zambia, Honduras and Sri Lanka found considerable frustration amongst media professionals, with what they felt was a severe lack of interest by editors.

Media owners are often concerned about short-term profits and may be unwilling to criticize industry, or offend advertisers. As many of the media houses operate on shoestring budgets, they often do not have adequate resources to undertake thorough investigation of climate-related stories.

Illiteracy too can be an obstacle to awareness, although the creation of online image banks of photographs and diagrams could help to convey the impacts of various facets of science.

There is also a need to build bridges between scientists and journalists. Scientists are often unwilling to simplify their research findings for a lay audience, so journalists have to sharpen their skills to simplify jargon heavy scientific content and make the subject more relevant and easier to understand.

We journalists too can do much to help ourselves. We can set up networks in order to share information. The Caribbean Environmental Reporters Network (CERN) and the Kenya Environment and Science Journalists Association (KENSJA) are good examples.

We also need to build bridges between the developed and developing environmental and science journalists so that we can exchange ideas and information.

Lack of pulling together-everyone with a stake in this problem - journalists, editors and publishers, NGOs, policy makers and funders, and of course the people of the developing world – are not pulling together to fill this grievous information gap. We need to do that.
