Climate change could deepen poverty in developing countries, study finds

WEST LAFAYETTE, Ind. - Urban workers could suffer most from climate change as the cost of food drives them into poverty, according to a new study that quantifies the effects of climate on the world's poor populations.

A team led by Purdue University researchers examined the potential economic influence of adverse climate events, such as heat waves, drought and heavy rains, on those in 16 developing countries. Urban workers in Bangladesh, Mexico and Zambia were found to be the most at risk.

"Extreme weather affects agricultural productivity and can raise the price of staple foods, such as grains, that are important to poor households in developing countries," said Noah Diffenbaugh, the associate professor of earth and atmospheric sciences and interim director of Purdue's Climate Change Research Center who co-led the study. "Studies have shown global warming will likely increase the frequency and intensity of heat waves, drought and floods in many areas. It is important to understand which socioeconomic groups and countries could see changes in poverty rates in order to make informed policy decisions."

The team used data from the late 20th century and projections for the late 21st century to develop a framework that examined extreme climate events, comparable shocks to grain production and the impact on the number of impoverished people in each country.
Thomas Hertel, a distinguished professor of agricultural economics and co-leader of the study, said that although urban workers only contribute modestly to total poverty rates in the sample countries, they are the most vulnerable group to changes in grains production.

"Food is a major expenditure for the poor and, while those who work in agriculture would have some benefit from higher grains prices, the urban poor would only get the negative effects," said Hertel, who also is executive director of Purdue's Center for Global Trade Analysis. "This is an important finding given that the United Nations projects a continuing shift in population concentrations from rural to urban areas in virtually all of these developing countries."

With nearly 1 billion of the world's poor living on less than $1 a day, extreme events can have a devastating impact, he said.

"Bangladesh, Mexico and Zambia showed the greatest percentage of the population entering poverty in the wake of extreme drought, with an additional 1.4 percent, 1.8 percent and 4.6 percent of their populations being impoverished by future climate extremes, respectively," Hertel said. "This translates to an additional 1.8 million people impoverished per country for Bangladesh and Mexico and an additional half million people in Zambia."

A paper detailing the work will be published in Thursday's (Aug. 20) issue of Environmental Research Letters. In addition to Diffenbaugh and Hertel, Syud Amer Ahmed, a recent Purdue graduate and a member of the development research group for The World Bank, co-authored the paper. The World Bank's Trust Fund for Environmentally and Socially Sustainable Development funded the research.

The team identified the maximum rainfall, drought and heat wave for the 30-year periods of 1971-2000 and 2071-2100 and then compared the maximums for the two time periods.

The global climate model experiments developed by the Intergovernmental Panel on Climate Change, or IPCC, were used for the future projections of extreme events. The team used an IPCC scenario that has greenhouse gas emissions continuing to follow the current trend, Diffenbaugh said.

"The occurrence and magnitude of what are currently the 30-year-maximum values for wet, dry and hot extremes are projected to substantially increase for much of the world," he said. "Heat waves and drought in the Mediterranean showed a potential 2700 percent and 800 percent increase in occurrence, respectively, and extreme rainfall in Southeast Asia was projected to potentially increase by 900 percent."

In addition, Southeast Asia showed a projected 40 percent increase in the magnitude of the worst rainfall; central Africa showed a projected 1000 percent increase in the magnitude of the worst heat wave; and the Mediterranean showed a projected 60 percent increase in the worst drought.

A statistical analysis was used to determine grain productivity shocks that would correspond in magnitude to the climate extremes, and then the economic impact of the supply shock was determined. Future predicted extreme climate events were compared to historical agricultural productivity extremes in order to assess the likely impact on agricultural production, prices and wages. Because the projected changes in extreme rainfall and heat wave events were too large for the current model to accept, only the extreme drought events were incorporated into the economic projections, making the projected poverty impacts a conservative estimate, he said.

To assess the potential economic impact of a given change in wages and grains prices, the team used data from each country's household survey. The estimates of likely wage and price changes following an extreme climate event were obtained from a global trade model, called the Global Trade Analysis Project, or GTAP, which is maintained by Purdue's agricultural economics department.

Purdue's GTAP framework is supported by an international consortium of 27 national and international agencies and is used by a network of 6,500 researchers in 140 countries.

Large reductions in grains productivity due to extreme climate events are supported by historical data. In 1991 grains productivity in Malawi and Zambia declined by about 50 percent when southern Africa experienced a severe drought.

Diffenbaugh said this is an initial quantification of how poverty is tied to climate fluctuations, and the team is working to improve the modeling and analysis system in order to enable more comprehensive assessments of the link between climate volatility and poverty vulnerability.

DES QUESTIONS ENVIRONNEMENTALES TRAITEES PAR LES PRESIDENTS KABILA ET KAGAME AU SOMMET DE GOMA

La rencontre au sommet entre les Présidents Joseph Kabila et Paul Kagame du 7 août 2009 dans la salle des conférences de l’hôtel Ihusi de Goma a aussi traitée des questions environnementales qui restent parmi les priorités dans la coopération entre les 2 pays de la région des grands lacs.
En effet, s’adressant à la presse dans la zone neutre séparant les villes de Goma et Gisenyi, les deux présidents ont affirmés qu’un regard devra être placé sur les questions de l’environnement au cours des différentes discutions entre les partenaires de cette région pour faciliter une intégration régionale sans faille dans toutes ses dimensions.
On devra cependant remarqué que le volet environnement est l’un des axes très développé entre le Rwanda et la RDC depuis des dizaines d’années,surtout quand on sait que l’habitat naturel des gorilles des montagnes du massif des Virunga est l’un des grand couloirs écologiques du monde qui facilite les mouvement sans passeport des animaux entre ces pays et la protection s’en suit sans casse par les institutions ayant en charge la conservation de la nature dans chacun des pays voisins.
Il existe même un accord de collaboration transfrontalière qui fait généré des recettes aux uns et aux autres qu’il s’agisse dans le tourisme que dans les échanges scientifiques.
Les 2 présidents ont soutenus avec intérêt que l’avenir entre le Rwanda et la RDC doit désormais compté sur les relations réchauffées par ce tête à tête tant attendu depuis plus de 12 ans car la dernière visite officielle d’un président Rwandais sur le sol congolais remonte au 29 Mai 1997 lors de la prestation de serment de feu Mzee Laurent Désiré Kabila à Kinshasa pendant le règne du Pasteur Bizimungu et la réplique congolaise s’était faite en septembre de la même année.
L’accueil de Paul Kagame à Goma par Joseph Kabila a eu lieu à la grande barrière sous le coup de 12h15, leur entretien sans témoins de l’hôtel Ihusi de plus d’une heure et demi s’est déroulé dans le calme et la sérénité ; car on a pu noté sur les visages des experts dans la cours de l’hôtel des assurances pour un lendemain meilleur.
La rencontre de Goma a surtout balisé le chemin d’avenir sur le plan politique, social, économique, culturel et scientifique surtout que l’on sait que la coopération dans les grands lacs passe par une entente sincère entre les habitants de la région et l’exemple venant d’en haut, les rwandais et congolais peuvent désormais croire à la fin de la guerre.
Les deux chefs d’états ont appréciés positivement les efforts de mettre fin à la présence des forces négatives encore actifs dans les forets congolaises par les opérations militaires en cours amorcées par « Umoja wetu », la nomination des ambassadeurs des deux pays,la relance de la CEPGL et autres. Kagame et Kabila ont soutenus que le partage des expériences dans l’extraction du gaz méthane déjà actif au Rwanda aidera les habitants de ce Lac Kivu à utiliser les ressources du gaz pour améliorer leur vie en bénéficiant de l’énergie.
C’est sur fond satisfaisant que les deux chefs d’états se sont séparé par la zone neutre de entre Goma et Gisenyi.

Climate change poker: The barriers which are preventing a global agreement

As the world's environment ministers, government officials, diplomats and campaigners prepare to attend the COP15 conference in Copenhagen in December 2009 to unite in the battle against climate change in one of the most complicated political deals the world has ever seen, the increasingly complex territory of climate negotiations is being revealed in an article published today, 5 August, 2009, in IOP Publishing's Environmental Research Letters.

The paper 'Tripping Points: Barriers and Bargaining Chips on the Road to Copenhagen' lays bare the main tripping points – political barriers and bargaining chips – which need to be overcome for countries to reach a consensus on how to address global climate change.

One of the key issues delegates will face in their attempt to agree on mitigation, is that what some countries see as barriers, others perceive as bargaining chips. While many developed countries, including the UK, favor extending mitigation actions to some developing countries, many developing countries will be using finance and technology transfer as a deal breaker for their consent to the overall deal.

Bargaining is expected to evolve around what is referred to as the 'chicken and egg question', that is whether actions depend on financing, or financing on actions. Researchers predict that similar to a poker game, countries will be delaying decisions until the last hours of the conference when all the bargaining chips will be on the table and parties cannot wait any longer to see who will show their hand first.

Other barriers delegates will face in their bid to reach an agreement on a post-2012 framework are issues evolving around the reduction of emissions from deforestation and forest degradation, and how to implement adaptation to climate change.

Even if some consensus is reached in Copenhagen, there is however no guarantee a deal will be agreed on. Nevertheless, the researchers write "Regardless, however, of the perspective from which one frames the discussions, success in Copenhagen and beyond will depend on parties' ability to negotiate past the tripping points […] by finding ways to match barriers with bargaining chips in envisioning how the details of any future agreement can be hammered out in the months and years to come."

17TH NILE COUNCIL OF MINISTERS IN CHARGE OF WATER AFFAIRS REAFFIRM BASIN-WIDE COOPERATION

Alexandria, Egypt
27-28 July 2009

The 17th annual meeting of the Nile Council of Ministers in charge of water affairs was held from 27 to 28 July 2009 in Alexandria, Egypt, upon the invitation of the Government of Egypt.

Ministers from Burundi, Democratic Republic of Congo, Egypt, Ethiopia, Kenya, Rwanda, Sudan, Tanzania and Uganda as well as Eritrea attended the meeting and held discussions on key strategic issues regarding the future of the Nile Basin Initiative, including the River Nile Cooperative Framework Agreement.

Ministers reaffirmed the determination of their respective Governments to strengthen basin-wide cooperation in the area of water resources management of the River Nile and beyond. They highlighted the critical importance of the Nile Basin Initiative’s Shared Vision to sustain this cooperation by achieving an inclusive agreement, underscoring the reality of the climate change phenomenon that brings countries ever closer to each other irrespective of geographical remoteness.

Reiterating the desire of the member states to move forward in the spirit of cooperation on the basis of ‘one Nile, one Basin and one Vision’, the ministers have decided to allow an additional period of six months to enable member states to move forward in concluding an inclusive treaty. They also expressed the wish for continued cooperation with the Development Partners.

In this regard, the ministers have mandated members of the Technical Advisory Committee and Negotiating Committee to consult with international experts and advise them on procedures for signing the Cooperative Framework Agreement. An Extraordinary Meeting of the Nile Council of Ministers will be convened to receive the report.

Convinced that these efforts towards advancing cooperation among their countries will also contribute to regional and global stability, peace and prosperity, and encouraged by the mutually unswerving commitment to pursue this path as displayed in the meeting, the Nile Basin countries expressed hope that their next meeting will mark the last step of signing of the Cooperative Framework Agreement.

---------------------------------
NOTE TO THE EDITOR
The Cooperative Framework Agreement is a proposed international treaty currently being negotiated among the countries which share the River Nile – Burundi, DR Congo, Egypt, Ethiopia, Kenya, Rwanda, Sudan, Tanzania, and Uganda (with Eritrea as an Observer). It lays down principles of cooperative water resources management and would establish a permanent Nile River Basin Commission.
