PESD partners Katharine Gratwick, Rebecca Ghanadan and Anton Eberhard have completed a case study on the experience of IPPs in Tanzania. The latest report is in addition to the PESD run study, Experience with Independent Power Projects in Developing Countries, exploring the factors that explain the patterns in IPP investment, and the legal and institutional mechanisms that could make the IPP mode of investment more sustainable. The Management Program Infrastructure Reform & Regulation (MIR) team has also revised previous case studies on Kenya and Egypt.

It is time to acknowledge that the international community's strategy on Zimbabwe has failed.

Robert G. Mugabe's regime has survived even as the economy deteriorates further (unemployment is above 70 percent, and gross domestic product will decline another 7 percent this year) and personal freedom suffers greater assaults (the recent "drive out the rubbish" campaign left 700,000 people homeless).

Indeed, with the opposition Movement for Democratic Change (MDC) on the verge of collapse - following a bitter fight over whether to boycott the recent Senate elections and after years of sustained government pressure - the regime has a stronger grasp on power than ever. Doddering though he may be, Mr. Mugabe, who recently turned 82, has foiled the pressure of the United States and Britain and the quiet diplomacy of his neighbors in southern Africa.

Predictions of imminent change still crop up in Western newspapers on the occasion of every new crisis in Zimbabwe. But these predictions have not come to bear, and they likely will not. So long as Mr. Mugabe reigns, his Zimbabwe African National Union-Patriotic Front (ZANU-PF) regime will survive.

The international community tried to change things. It embarked on a strategy of concerted economic and diplomatic pressure to weaken the Mugabe regime, trying to force it to either back down or submit to the democratic opposition. It's clear that strategy has failed.

It is, therefore, time to focus international attention on the prospect of Zimbabwe's only genuine political opening in the years ahead: the exit of Mr. Mugabe, whether through retirement or death, which will leave the regime internally and externally vulnerable.

Internally, the ZANU-PF regime without Mr. Mugabe at the helm will be uniquely susceptible in an election. In sub-Saharan Africa, opposition candidates have won post-transitional elections only 5 percent of the time against incumbents but 33 percent of the time against regimes' designated successors.

The most important reason for that is the incumbent's exit removes the regime's glue. The regime fractures into competing factions and is left with a substantially reduced capacity to repress the political opposition and rig an election.

In Kenya, after President Daniel T. arap Moi, and in Ghana, after President Jerry J. Rawlings, the regimes did not - could not - resort to all the dirty tactics that they certainly would have used had the incumbents run. In turn, these political openings have tended to galvanize the fractured opposition to successfully cooperate.

A ZANU-PF that is deeply unpopular, badly fractured among ethnic groups and between moderates and hard-liners (the expulsion of the information minister, Jonathan Moyo, is the beginning) and facing a reinvigorated opposition will not likely be able to effectively rig elections, let alone win the popular vote.

It will be critical, then, that presidential elections be held within a year of Mr. Mugabe's exit, before the regime has too much time to consolidate. If Mr. Mugabe's exit does not occur within that window before the 2008 elections, then international, and particularly regional, pressure will be crucial in forcing early elections.

Externally, Mr. Mugabe's exit may prompt genuine regional pressure. Analysts have long emphasized that international pressure requires the support of Zimbabwe's neighbors - especially South Africa - that have significant political and economic leverage. But to the great frustration of Western governments, southern African countries have thus far refused to publicly challenge Mr. Mugabe.

Their reluctance has much to do with Mr. Mugabe's status as a hero of Zimbabwe's anti-colonial struggle and a champion of liberation struggles elsewhere. Southern African nations will have much greater political room to apply real pressure on Zimbabwe when its leader lacks such credentials.

Simultaneously, the prospect of an altogether different level of violence might shake the complacency of southern African nations. Zimbabwe's implosion has not, thus far, been entirely bad for its neighbors. They have benefited from the elimination of economic competition and from the influx of professionals, and they have retained confidence that Mr. Mugabe can keep control.

But there is a real danger, if a post-Mugabe Zimbabwe is not handled adroitly, that elements of the opposition, disaffected war veterans and youth militia and losers in the ZANU-PF factional battle will take up arms and plunge Zimbabwe into civil war.

This specter should push neighboring countries to step up their efforts, especially to press the post-Mugabe regime to hold new presidential elections and encourage moderate elements within ZANU-PF.

Notwithstanding its occasional fulminations against Zimbabwe, the United States has failed in its efforts to unseat Mr. Mugabe's regime. The United States should focus now on his eventual exit by helping the MDC to overcome its bitter infighting and engaging Zimbabwe's neighbors, especially South Africa, in vigorous diplomacy, pushing them to prepare for the occasion.

The stakes could not be higher, for if the post-Mugabe period is the first genuine opportunity for political change in Zimbabwe, it may also be the last for some time.

SEATTLE - There are a billion hungry people in the world. Fifteen thousand children-the equivalent of five times the victims of the World Trade Center bombings-die each day of hunger. Yet it doesn't have to be this way. We can end hunger-if we make a commitment to doing so. The new one-hour documentary Silent Killer: The Unfinished Campaign Against Hunger shows how it can be done. Shot on location in the United States, South Africa, Kenya, Rome, Mexico and Brazil, Silent Killer examines both the problem of hunger and solutions. The documentary and its companion Web site (www.SilentKillerFilm.org) will provide viewers with inspiration and information to become part of the effort to end hunger.

Produced by Hana Jindrova and John de Graaf (Affluenza, Escape from Affluenza), in association with KCTS/Seattle Public Television, Silent Killer will air on several California public television stations as follows:

KTEH/ San Jose: Sunday, October 16 at 5:00 p.m. (please confirm).

Narrated by National Public Radio's Scott Simon, the film begins in South Africa's Kalahari Desert, where razor-thin Bushmen use the Hoodia cactus to fend off hunger. But now, a drug firm has patented the Hoodia's appetite-suppressant properties and is using it to make a diet product for obese Americans and Europeans. Hoodia is a metaphor for a world where some people die from too much food, but millions more die from too little.

We discover how serious the problem is in Kenya as we meet Jane Ininda, a scientist who is trying to make agriculture more productive in her country, while her own brother, Salesio, barely survives the drought, poor soils and pests that constantly threaten his crops. Through powerful stories, we come to understand the dimensions of the hunger crisis.

At the World Food Summit in Rome, we learn how activists have been working to end hunger since President John Kennedy declared war on it in 1963. But today, America's commitment to food security is less clear. In fact, world financial commitments to hunger research are now in decline.

But Silent Killer does not leave viewers feeling helpless. A visit to Brazil finds a nation energized by a new campaign called FOME ZERO-Zero Hunger. In the huge city of Belo Horizonte, we meet a remarkable leader and see how, under the programs she supervises, the right to food is guaranteed to all. In the countryside, we are introduced to the Landless Peasants' Movement, which is giving hope to millions of hungry Brazilians.

Can we end hunger, or will it always be with us? Why should we try? What will it take? What are we doing now? Can biotechnology play a role, and if so, how? Is hunger just a problem of distribution, or do we still need to produce more and better crops? These are the questions considered in this exquisitely photographed documentary.
