Estimated $18 Billion Reconstruction 

To begin with, projected reconstruction costs to rebuild Gaza currently total $18 billion, said Galit Cohen, director of the Program on Climate Change at the Israel Institute for National Security. She has experience identifying and analyzing risks and opportunities for Israel’s national security in the field of climate change.

Water, sewage, waste, food and air pollution risks abound in Gaza, which is one of the most densely populated areas in the world, Cohen said. At least 57 percent of water, sanitation and health facilities in Gaza have been destroyed so far, including desalinization plants, and only 3-7 liters of water is typically available per day for each person, which is well below the recommended minimum of 50-100 liters.

“In the current situation in regard to the environmental issues, it's about the water security and about the sewage, sanitation and construction waste – all the list of those issues that need to be mitigated and also dealt with,” Cohen said. For example, “there is no active wastewater treatment facility now in Gaza,” and the many unclaimed dead bodies deep in the rubble pose environmental risks as well.

As for solutions, she said, “Trying to build the institutions and the government that can undertake the responsibility of the civil society there” is the first step to working together on a rebuild of Gaza. The goal should be to create a new coalition with the U.S. and countries such as Egypt, Jordan, UAE, and Saudi Arabia (and others) that can undertake a reconstruction of Gaza so Palestinians can live there without enduring an environmental catastrophe.

“This is the only way we can survive here – Israel and all the rest,” Cohen said.
 

Coalition Building

Dr. Tareq Abu Hamed, director of the Arava Institute for Environmental Studies, described the sensitive environmental interdependence of countries in the region.

“The streams and rivers originating in Israel and the West Bank originate in Jordan, and in Israel the vast majority of the aquifers of underground water in our region is shared between Israel and its neighbors – between Jordan and its neighbors, and it’s shared between Palestine and its neighbors. That means if there’s an environmental challenge or an environmental issue with the water that we have, one country alone cannot deal with it. Regional cooperation is a must,” he said.

Dr. Hamed has served as the Israeli Ministry of Science’s Deputy Chief Scientist, and later the Acting Chief Scientist, and was the highest ranking Palestinian in the Israeli government. About his current position at the Arava Institute, he said, “We use the environment as a tool. We use science as [a] diplomacy tool to bring people together. We use science to build bridges, to build trust, and to build understanding.”

The regional effects in climate change could be exacerbated by the war in Gaza, he said. “The region that we live in is a hotspot when it comes to climate change, the heat waves, and the sea level rise.”

The warming of the Eastern Mediterranean is increasing, and it is already much higher than any other place in the world, he said. On top of this, climate change often produces migration to other areas, creating possible instability effects for existing populations in the new areas, and statistics show people already have been moving out of Gaza and other countries in the immediate region, likely due to the worsening climate, and in addition now, to the conflict.

He said the intense bombing of Gaza has significantly damaged farmlands, infrastructure, including apartment buildings, the roads, water treatment plants, wastewater treatment plants and water wells. “What happened on Oct. 7 happened because of the lack of knowledge of the other side.” 

He added, “This is a great chance for us to rethink what happened and to rebuild a better future for all of us.”
 

Renewable Energy Concerns – or Opportunity?

The war in Gaza seriously affects the prospect of green or renewable energy in the immediate conflict area, said Dorit Banet, who co-founded the Eilat-Eilot Renewable Energy Initiative and has been Israel’s leading government official in the area of renewable energy for two decades.

More than 100,000 Israelis were estimated to be displaced from their homes in southern Israel after Oct. 7. Banet has noted in prior media stories that some in Israel are eying a push to “build back better” by transforming the region into a more sustainable area. Israel has committed to reaching 30% renewable energy by 2030, though that may be difficult.

Banet said at least another 2 gigawatts of solar renewable energy could be immediately produced in one particular Israeli area based on the existing infrastructure – and eventually as much as another 8.5 gigawatts of solar energy. 

This would offer people in the area much more energy resilience, she said. “In such areas, this needs to be totally agreed upon with totally new regulation in Israel.”
 

Promoting Resilience

Victor Weiss, director of sustainability for the Israel National Security Council, said the ongoing war could have a negative impact on the global economy, the availability of budget, and the willingness of countries to allocate resources to climate issues.   

“A regional war is expected to affect fuel markets and lead to damaged supply chains” and the general instability of markets, said Weiss, who was a senior military officer and founder of the Israel Defense Force’s Environmental Unit.

“We have to build a new relationship and partnerships with the other regional countries to promote resilience,” he added.

Weiss said that Israel’s National Security Council recently defined climate issues as a strategic threat to that country’s national security. “The climate chapter was written in the National Security Council Risk Assessment and the main threats were mapped. We are working to define the threats, to formulate the national response to those threats,” he said.

An opportunity exists for Israel, Gaza and every population affected by this conflict to “go forward on the hope of an optimistic future to our region,” he said.

‘Powerful, Informative’

In closing, Prof. Diamond described the discussion as “very powerful, informative and in the end, also moving” for the audience. “There’s going to be a staggering challenge of reconstruction when this war is over, and hopefully we can get started on it as soon as possible.”

Alon Tal added, “We’ve only begun this discussion about the reconstruction. Let’s hope that very quickly we can end the destruction, the death and the suffering, and move forward to a time of renewal.”
