Blue Revolution Key to Getting "More Crop per Drop" and Strengthening Food Security
Worldwatch Institute's Nourishing the Planet team highlights low-cost, small-scale initiatives to effectively manage water resources in agriculture
WASHINGTON
Increasing demand for water continues to threaten the livelihood of millions of small-scale farmers who depend on water for their crops. At a time when one in eight people lacks access to safe water, the Worldwatch Institute's Nourishing the Planet project (www.NourishingthePlanet.org) points to low-cost, small-scale innovations to better manage this vital resource. Worldwatch's recently released State of the World 2011: Innovations that Nourish the Planet report showcases initiatives to increase the availability of water for crops that can help farmers improve crop productivity and become more food-secure.
Seventy percent of the world's freshwater is used for irrigation, and global water resources are drying up as climate change takes hold and population growth continues. Sixty percent of the world's hungry people live in South Asia and sub-Saharan Africa - most of them on small farms - where they do not have a reliable source of water to produce sufficient yields. "In sub-Saharan Africa, for example, only 4 percent of the cultivated land is currently equipped for irrigation, compared with 18 percent in the rest of the world. But there is great potential to expand irrigation with small-scale solutions," says Danielle Nierenberg, Nourishing the Planet co-project director.
The Green Revolution of the 1960s led to a near tripling of global grain production and a doubling of the world's irrigated area. It also demanded vast quantities of water. Agricultural investments have tended to focus narrowly on increasing crop yields, but there has been relatively little research and investment in ways to make better use of scarce water resources.
"As global food markets become increasingly volatile, efficient water management on farmers' fields can help strengthen food self-sufficiency in the long-term," says Nierenberg. Affordable innovations that boost agricultural development and meet the increasing demand on already-scarce water resources while also mitigating the impacts of climate change are more important than ever.
Over the past 15 months, the Nourishing the Planet team conducted on-the-ground research in 25 countries in sub-Saharan Africa. Researchers met with over 250 farmers' groups, scientists, NGOs, and government agencies that are working to alleviate hunger and poverty while also protecting the environment. "These innovations highlight agriculture's untapped potential to address some of the world's most daunting problems, especially in sub-Saharan Africa, where hunger and poverty are deeply entrenched," says Brian Halweil, Nourishing the Planet co-project director.
In sub-Saharan Africa, 95 percent of cropland depends on rain, and climate scientists predict that rainfall on the continent will decline in the coming decades. "Rain-fed areas with low agricultural yields, such as much of Africa, hold the biggest potential for getting 'more crop per drop,'" says Sandra Postel, director of the Global Water Policy Project and State of the World 2011 contributing author.
Nourishing the Planet recommends three models for effective water management that can be replicated and scaled-up around the world:
Human-powered pumps. The foot-operated treadle pump enables 2.3 million farmers in the developing world - some 250,000 in sub-Saharan Africa - to boost crop productivity, improve harvest reliability, and raise incomes. The original $35 version can irrigate 0.2 hectares with ground water; newer models can irrigate up to 0.8 hectares and cost no more than $140 installed. These devices already generate $37 million a year in profits and wages. In Zambia, International Development Enterprises worked with farmers to determine the most effective type of pump. The Mosi-O-Tunya pump is manufactured locally and delivers 25 percent more water per second than older versions.
Affordable micro-irrigation. A suite of low-cost drip irrigation technologies is helping farmers use limited water supplies more efficiently, often doubling water productivity. These systems deliver water directly to the plant roots through perforated pipes or tubes, and can come in the form of $5 bucket kits, $25 drum kits, or $100 shiftable drip systems that irrigate up to 0.2 hectares. Solar-powered micro-irrigation drip systems are also making their debut in West Africa. One study found that after a year of using these systems, villagers in Benin had higher incomes and protein in their diets. Children attended school more often, since they no longer needed to spend their day collecting water.
More effective use of rainfall. Conservation tillage methods that leave the soil intact; timely weeding and mulching; and planting vegetative barriers, all help to maximize green water, or rainwater stored in the soil and plants as moisture. Rainwater harvesting using small earthen dams and other methods also helps maximize rainwater utility. Supplementing these practices with irrigation may produce optimal results. In Kenya, Maasai women are working with the U.N. Environment Programme and the World Agroforestry Centre to build rooftop catchment tanks, which provide water for their households and save women time collecting water.
Satisfying the water requirements of the future while also coping with population growth, increasing consumption, persistent poverty, and a changing climate will take a commitment well beyond what has materialized to date. Support - and research and investment - from governments, development agencies, and international and national NGOs can help make such technologies more accessible to smallholder farmers.
State of the World 2011: Innovations that Nourish the Planet is accompanied by informational materials including briefing documents, summaries, an innovations database, videos, and podcasts, all available at www.NourishingthePlanet.org. The project's findings are being disseminated to a wide range of agricultural stakeholders, including government ministries, agricultural policymakers, and farmer and community networks, as well as the increasingly influential nongovernmental environmental and development communities.

At Least 95 Palestinians Killed in Israeli Attacks Including Massacres at Beach Café, Aid Points
"I saw body parts flying everywhere, and bodies cut and burned," said one eyewitness to a strike on the popular al-Baqa Café.
Jun 30, 2025
Israeli forces ramped up their genocidal assault on the Gaza Strip Monday, killing at least 95 Palestinians in attacks including massacres at a seaside café and a humanitarian aid distribution center and bombings of five school shelters housing displaced families and a hospital where refugees were sheltering in tents.
An Israeli strike targeted the al-Baqa Café in western Gaza City, one of the few operating businesses remaining after 633 days of Israel's obliteration of the coastal strip and a popular gathering place for journalists, university students, artists, and others seeking reliable internet service and a respite from nearly 21 months of near-relentless attacks.
Medical sources said at least 33 civilians were killed and nearly 50 others wounded in the massacre, including footballer Mustafa Abu Amira, photojournalist Ismail Abu Hatab—who survived an earlier Israeli airstrike and is reportedly the 227th journalists killed by Israel since October 2023—and prominent artist Frans Al-Salmi, whose final painting depicting a young Palestinian woman killed by Israeli forces resembles photographs of its slain creator posted on social media after her killing.
Warning: Photos shows image of death
Survivor Ali Abu Ateila toldThe Associated Press that the café was crowded with women and children at the time of the attack.
"Without a warning, all of a sudden, a warplane hit the place, shaking it like an earthquake," he said.
Another survivor of the massacre told Britain's Sky News: "All I see is blood... Unbelievable. People come here to take a break from what they see inside Gaza. They come westward to breathe."
Eyewitness Ahmed Al-Nayrab toldAgence France-Presse that a "huge explosion shook the area."
"I saw body parts flying everywhere, and bodies cut and burned," he said. "It was a scene that made your skin crawl."
Witnesses and officials said Israeli Defense Forces (IDF) troops opened fire on Palestinians seeking food and other humanitarian aid from a U.S.-backed Gaza Humanitarian Foundation distribution point in southern Gaza, killing 15 people amid near-daily massacres of aid-seekers.
"We were targeted by artillery," survivor Monzer Hisham Ismail told The Associated Press. Another survivor, Yousef Mahmoud Mokheimar, told the AP that Israeli troops "fired at us indiscriminately." Mokheimar was shot in the leg, another man who tried to rescue him was also shot.
IDF troops have killed nearly 600 Palestinian aid-seekers and wounded more than 4,000 others over the past month, with Israeli military officers and soldiers saying they were ordered to deliberately fire on civilians in search of food and other necessities amid Israel's weaponized starvation of Gaza.
Another 13 people were reportedly killed Monday when IDF warplanes bombed an aid warehouse in the Zeitoun quarter of southern Gaza City, according to al-Ahli Baptist Hospital officials cited by The Palestine Chronicle. IDF warplanes also reportedly bombed five schools housing displaced families, three of them in Zeitoun. Israeli forces also bombed the courtyard of al-Aqsa Hospital in Deir al-Balah in central Gaza, where thousands of forcibly displaced Palestinian families are sheltering in tents. It was reportedly the 12th time the hospital has been bombed since the start of the war.
The World Health Organization has documented more than 700 attacks on Gaza healthcare facilities since October 2023. Most of Gaza's hospitals are out of service due to Israeli attacks, some of which have been called genocidal by United Nations experts.
Israel's overall behavior in the war is the subject of an ongoing International Court of Justice genocide case, while Israeli Prime Minister Benjamin Netanyahu is wanted by the International Criminal Court for alleged war crimes and crimes against humanity in Gaza, including murder and using starvation as a weapon of war.
Since October 2023, Israeli forces have killed or wounded more than 204,000 Palestinians in Gaza, including over 14,000 people who are missing and presumed dead and buried under rubble, according to the Gaza Health Ministry, whose casualty figures have been found to be generally accurate and even a likely undercount by peer-reviewed studies.
The intensified IDF attacks follow Israel's issuance of new forced evacuation orders amid the ongoing Operation Gideon's Chariots, an ongoing offensive which aims to conquer and indefinitely occupy all of Gaza and ethnically cleanse much of its population, possibly to make way for Jewish recolonization as advocated by many right-wing Israelis.

'We Cannot Be Silent': Tlaib Leads 19 US Lawmakers Demanding Israel Stop Starving Gaza
"This current blockade is starving Palestinian civilians in violation of international law, and the militarization of food will not help."
Jun 30, 2025
As the death toll from Israel's forced starvation of Palestinians continues to rise amid the ongoing U.S.-backed genocidal assault and siege of the Gaza Strip, Rep. Rashida Tlaib on Monday led 18 congressional colleagues in a letter demanding that the Trump administration push for an immediate cease-fire, an end to the Israeli blockade, and a resumption of humanitarian aid into the embattled coastal enclave.
"We are outraged at the weaponization of humanitarian aid and escalating use of starvation as a weapon of war by the Israeli government against the Palestinian people in Gaza," Tlaib (D-Mich.)—the only Palestinian American member of Congress—and the other lawmakers wrote in their letter to U.S. Secretary of State Marco Rubio. "For over three months, Israeli authorities have blocked nearly all humanitarian aid from entering Gaza, fueling mass starvation and suffering among over 2 million people. This follows over 600 days of bombardment, destruction, and forced displacement, and nearly two decades of siege."
"According to experts, 100% of the population is now at risk of famine, and nearly half a million civilians, most of them children, are facing 'catastrophic' conditions of 'starvation, death, destitution, and extremely critical acute malnutrition levels,'" the legislators noted. "These actions are a direct violation of both U.S. and international humanitarian law, with devastating human consequences."
Gaza officials have reported that hundreds of Palestinians—including at least 66 children—have died in Gaza from malnutrition and lack of medicine since Israel ratcheted up its siege in early March. Earlier this month, the United Nations Children's Fund warned that childhood malnutrition was "rising at an alarming rate," with 5,119 children under the age of 5 treated for the life-threatening condition in May alone. Of those treated children, 636 were diagnosed with severe acute malnutrition, the most lethal form of the condition.
Meanwhile, nearly 600 Palestinians have been killed and more than 4,000 others have been injured as Israeli occupation forces carry out near-daily massacres of desperate people seeking food and other humanitarian aid at or near distribution sites run by the U.S.-backed Gaza Humanitarian Foundation (GHF). Israel Defense Forces officers and troops have said that they were ordered to shoot and shell aid-seeking Gazans, even when they posed no threat.
"This is not aid," the lawmakers' letter argues. "UNRWA Commissioner-General Philippe Lazzarini has warned that, under the GHF, 'aid distribution has become a death trap.' We cannot allow this to continue."
"We strongly oppose any efforts to dismantle the existing U.N.-led humanitarian coordination system in Gaza, which is ready to resume operations immediately once the blockade is lifted," the legislators wrote. "Replacing this system with the GHF further restricts lifesaving aid and undermines the work of long-standing, trusted humanitarian organizations. The result of this policy will be continued starvation and famine."
"We cannot be silent. This current blockade is starving Palestinian civilians in violation of international law, and the militarization of food will not help," the lawmakers added. "We demand an immediate end to the blockade, an immediate resumption of unfettered humanitarian aid entry into Gaza, the restoration of U.S. funding to UNRWA, and an immediate and lasting cease-fire. Any other path forward is a path toward greater hunger, famine, and death."
Since launching the retaliatory annihilation of Gaza in response to the Hamas-led October 7, 2023 attack on Israel, Israeli forces have killed at least 56,531 Palestinians and wounded more than 133,600 others, according to the Gaza Health Ministry, which also says over 14,000 people are missing and presumed dead and buried beneath rubble. Upward of 2 million Gazans have been forcibly displaced, often more than once.
On Sunday, U.S. President Donald Trump reiterated a call for a cease-fire deal that would secure the release of the remaining 22 living Israeli and other hostages held by Hamas.
In addition to Tlaib, the letter to Rubio was signed by Sen. Bernie Sanders (I-Vt.) and Democratic Reps. Greg Casar (Texas), Jesús "Chuy" García (Ill.), Al Green (Texas), Jonathan Jackson (Ill.), Pramila Jayapal (Wash.), Henry "Hank"Johnson (Ga.), Summer Lee (Pa.), Jim McGovern (Mass.), Alexandria Ocasio-Cortez (N.Y.), Ilhan Omar (Minn.), Chellie Pingree (Maine), Mark Pocan (Wisc.), Ayanna Pressley (Mass.), Delia Ramirez (Ill.), Paul Tonko (N.Y.), Nydia Velázquez (N.Y.), and Bonnie Watson Coleman (N.J.).

Biden National Security Adviser Among Those Crafting 'Project 2029' Policy Agenda for Democrats
"Jake Sullivan's been a critical decision-maker in every Democratic catastrophe of the last decade," said one observer. "Why is he still in the inner circle?"
Jun 30, 2025
Amid the latest battle over the direction the Democratic Party should move in, a number of strategists and political advisers from across the center-left's ideological spectrum are assembling a committee to determine the policy agenda they hope will be taken up by a Democratic successor to President Donald Trump.
Some of the names on the list of people crafting the agenda—named Project 2029, an echo of the far-right Project 2025 blueprint Trump is currently enacting—left progressives with deepened concerns that party insiders have "learnt nothing" and "forgotten nothing" from the president's electoral victories against centrist Democratic candidates over the past decade, as one economist said.
The project is being assembled by former Democratic speechwriter Andrei Cherny, now co-founder of the policy journal Democracy: A Journal of Ideas, and includes Jake Sullivan, a former national security adviser under the Biden administration; Jim Kessler, founder of the centrist think tank Third Way; and Neera Tanden, president of the Center for American Progress and longtime adviser to former Secretary of State Hillary Clinton.
Progressives on the advisory board for the project include economist Justin Wolfers and former Roosevelt Institute president Felicia Wong, but antitrust expert Hal Singer said any policy agenda aimed at securing a Democratic victory in the 2028 election "needs way more progressives."
As The New York Times noted in its reporting on Project 2029, the panel is being convened amid extensive infighting regarding how the Democratic Party can win back control of the White House and Congress.
After democratic socialist and state Assemblymember Zohran Mamdani's (D-36) surprise win against former New York Gov. Andrew Cuomo last week in New York City's mayoral primary election—following a campaign with a clear-eyed focus on making childcare, rent, public transit, and groceries more affordable—New York City has emerged as a battleground in the fight. Influential Democrats including House Minority Leader Hakeem Jeffries (D-N.Y.) and Sen. Kirsten Gillibrand (D-N.Y.) have so far refused to endorse him and attacked him for his unequivocal support for Palestinian rights.
Progressives have called on party leaders to back Mamdani, pointing to his popularity with young voters, and accept that his clear message about making life more affordable for working families resonated with Democratic constituents.
But speaking to the Times, Democratic pollster Celinda Lake exemplified how many of the party's strategists have insisted that candidates only need to package their messages to voters differently—not change the messages to match the political priorities of Mamdani and other popular progressives like Sen. Bernie Sanders (I-Vt.) and Rep. Alexandria Ocasio-Cortez (D-N.Y.).
"We didn't lack policies," Lake told the Times of recent national elections. "But we lacked a functioning narrative to communicate those policies."
Sanders and Ocasio-Cortez have drawn crowds of thousands in red districts this year at Sanders' Fighting Oligarchy rallies—another sign, progressives say, that voters are responding to politicians who focus on billionaires' outsized control over the U.S. political system and on economic justice.
Project 2029's inclusion of strategists like Kessler, who declared economic populism "a dead end for Democrats" in 2013, demonstrates "the whole problem [with Democratic leadership] in a nutshell," said Jonathan Cohn of Progressive Mass—as does Sullivan's seat on the advisory board.
As national security adviser to President Joe Biden, Sullivan played a key role in the administration's defense and funding of Israel's assault on Gaza, which international experts and human rights groups have said is a genocide.
"Jake Sullivan's been a critical decision-maker in every Democratic catastrophe of the last decade: Hillary Clinton's 2016 campaign, the withdrawal from Afghanistan, the Israel/Gaza War, and the 2024 Joe Biden campaign," said Nick Field of the Pennsylvania Capital-Star. "Why is he still in the inner circle?"
"Jake Sullivan is shaping domestic policy for the next Democratic administration," he added. "Who is happy with the Biden foreign policy legacy?"
