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.
The Worldwatch Institute was a globally focused environmental research organization based in Washington, D.C., founded by Lester R. Brown. Worldwatch was named as one of the top ten sustainable development research organizations by Globescan Survey of Sustainability Experts. Brown left to found the Earth Policy Institute in 2000. The Institute was wound up in 2017, after publication of its last State of the World Report. Worldwatch.org was unreachable from mid-2019.

Trump Signs Executive Order to Advance 'Deeply Dangerous' Deep-Sea Mining
"The harm caused by deep-sea mining isn't restricted to the ocean floor: It will impact the entire water column, top to bottom, and everyone and everything relying on it," one campaigner warned.
Apr 24, 2025
Amid global calls for a ban on deep-sea mining to protect marine ecosystems, U.S. President Donald Trump on Thursday signed an executive order to advance the risky practice and "restore American dominance in offshore critical minerals and resources."
"The broad order avoids a direct confrontation with the United Nations-backed International Seabed Authority and seeks essentially to jump-start the mining of U.S. waters as part of a push to offset China's sweeping control of the critical minerals industry," notedReuters, which had previewed the measure aimed at attaining nickel, cobalt, copper, manganese, titanium, and rare earth elements.
"The International Seabed Authority—created by the United Nations Convention on the Law of the Sea, which the U.S. has not ratified—has for years been considering standards for deep-sea mining in international waters, although it has yet to formalize them due to unresolved differences over acceptable levels of dust, noise, and other factors from the practice," the agency reported.
Trump's order directs Cabinet members including Secretary of Commerce Howard Lutnick—whose department oversees the National Oceanic and Atmospheric Administration (NOAA)—to expedite the permit process and work on various related reports.
"Authorizing deep-sea mining outside international law is like lighting a match in a room full of dynamite—it threatens ecosystems, global cooperation, and U.S. credibility all at once."
Deep-sea mining is opposed by over 30 countries as well as academics and advocacy groups worldwide. Among them is Greenpeace USA, whose campaigner Arlo Hemphill said Thursday that "authorizing deep-sea mining outside international law is like lighting a match in a room full of dynamite—it threatens ecosystems, global cooperation, and U.S. credibility all at once."
"We condemn this administration's attempt to launch this destructive industry on the high seas in the Pacific by bypassing the United Nations process," Hemphill declared. "This is an insult to multilateralism and a slap in the face to all the countries and millions of people around the world who oppose this dangerous industry."
"But this executive order is not the start of deep-sea mining. Everywhere governments have tried to start deep-sea mining, they have failed. This will be no different," he added. "We call on the international community to stand against this unacceptable undermining of international cooperation by agreeing to a global moratorium on deep-sea mining. The United States government has no right to unilaterally allow an industry to destroy the common heritage of humankind, and rip up the deep sea for the profit of a few corporations."
No exaggeration, deep sea mining could cause the massive collapse of the entire deep sea ecosystem and food chain. This is an existential risk to every person on this planet. www.nytimes.com/2025/04/24/c...

Ocean Conservancy vice president for external affairs Jeff Watters also blasted the move, saying that "this executive order flies in the face of NOAA's mission. NOAA is charged with protecting, not imperiling, the ocean and its economic benefits, including fishing and tourism; and scientists agree that deep-sea mining is a deeply dangerous endeavor for our ocean and all of us who depend on it."
"Areas of the U.S. seafloor where test mining took place over 50 years ago still haven't fully recovered," Watters pointed out. "The harm caused by deep-sea mining isn't restricted to the ocean floor: It will impact the entire water column, top to bottom, and everyone and everything relying on it. Evidence tells us that areas targeted for deep-sea mining often overlap with important fisheries, raising serious concerns about the impacts on the country's $321 billion fishing industry."
He highlighted that "NOAA is already being threatened by this administration's unprecedented cuts. NOAA is the eyes and ears for our water and air. NOAA provides Americans with accessible and accurate weather forecasts; it tracks hurricanes and tsunamis; it responds to oil spills; it keeps seafood on the table; and so much more. Forcing the agency to carry out deep-sea mining permitting while these essential services are slashed will only harm our ocean and our country."
"It's not just our country this executive order would harm: This action has far-reaching implications beyond the U.S.," Watters added, warning that by unilaterally allowing deep-sea mining, "the administration is opening a door for other countries to do the same—and all of us, and the ocean we all depend on, will be worse off for it."
As The New York Timesreported:
The executive order could pave the way for the Metals Company, a prominent seabed mining company, to receive an expedited permit from NOAA to actively mine for the first time. The publicly traded company, based in Vancouver, British Columbia, disclosed in March that it would ask the Trump administration through a U.S. subsidiary for approval to mine in international waters. The company has already spent more than $500 million doing exploratory work.
"We have a boat that's production-ready," said Gerard Barron, the company's chief executive, in an interview on Thursday. "We have a means of processing the materials in an allied friendly partner nation. We're just missing the permit to allow us to begin."
In response to the late March disclosure—which came during International Seabed Authority negotiations—Louisa Casson, senior campaigner for Greenpeace International, said that "this is another of the Metals Company's pathetic ploys and an insult to multilateralism. It shows that a moratorium on deep-sea mining is more urgently needed than ever. It also proves that the company's CEO Gerard Barron's plans never focused on solutions for the climate catastrophe."
"The Metals Company is desperate and now is encouraging a breach of customary international law by announcing their intent to mine the international seabed through the United States' Deep-Sea Hard Mineral Resources Act," the camapigner asserted. "This comes after the Metals Company has spent years exerting immense pressure on the International Seabed Authority to try and force governments to allow mining in the international seabed—the common heritage of humankind."
Casson stressed that "states, civil society, scientists, companies, and Indigenous communities continue to resist these efforts. Having tried and failed to pressure the international community to meet their demands, this reckless announcement is a slap in the face to international cooperation."
Less than a week later, the Norwegian deep-sea mining company Loke Marine Minerals declared bankruptcy—which Haldis Tjeldflaat Helle, a campaigner for Greenpeace Nordic, noted came "on the same day that we shut down a deep-sea mining conference in Bergen."
The Norwegian government in December halted plans to move forward with deep-sea mining in the Arctic Ocean, which Steve Trent, CEO and founder of the Environmental Justice Foundation, had called "a testament to the power of principled, courageous political action, and... a moment to celebrate for environmental advocates, ocean ecosystems, and future generations alike."

Doctors Without Borders Says Trump Aid Cuts 'Are a Human-Made Disaster' for Millions
"We are an emergency response organization, but we have never seen anything like this massive disruption to global health and humanitarian programs."
Apr 24, 2025
As the Trump administration, spearheaded by Elon Musk's Department of Government Efficiency, dramatically slashes U.S. humanitarian assistance, the international medical charity Doctors Without Borders warned Thursday that the cuts are already "having devastating consequences for people who rely upon aid" across the Global South.
"The U.S. has long been the leading supporter of global health and humanitarian programs, responsible for around 40% of all related funding," Doctors Without Borders, known by its French acronym MSF, said in a statement. "These U.S. investments have helped improve the health and well-being of communities around the globe—and totaled less than 1% of the annual federal budget."
"It's shocking to see the U.S. abandon its leadership role in advancing global health and humanitarian efforts."
However, with the Trump administration slashing funding for U.S. Agency for International Development (USAID) contracts by 90%, including for programs that fed and provided healthcare for millions of people and fought diseases like malaria and HIV/AIDS, MSF USA CEO Avril Benoît said there will be "more preventable deaths and untold suffering around the world."
"These sudden cuts by the Trump administration are a human-made disaster for the millions of people struggling to survive amid wars, disease outbreaks, and other emergencies," Benoît warned. "We are an emergency response organization, but we have never seen anything like this massive disruption to global health and humanitarian programs."
"The risks are catastrophic, especially since people who rely on foreign assistance are already among the most vulnerable in the world," she added.
Although MSF received no U.S. government funding, the group noted that "we work closely with other health and humanitarian organizations to deliver vital services, and many of our activities involve programs that have been disrupted due to funding cuts."
"It will be much more difficult and costly to provide care when so many ministries of health have been affected globally and there are fewer community partners overall," the group said. "We will also be facing fewer places to refer patients for specialized services, as well as shortages and stockouts due to hamstrung supply chains."
"It's shocking to see the U.S. abandon its leadership role in advancing global health and humanitarian efforts," Benoît said. "U.S. assistance has been a lifeline for millions of people... We urge the administration and Congress to maintain commitments to support critical global health and humanitarian aid."
The MSF warning comes after the United Nations World Food Program said earlier this month that the Trump cuts to lifesaving aid programs "could amount to a death sentence for millions of people facing extreme hunger and starvation."

UN Chief Urges 'Maximum Restraint' as India-Pakistan Tensions Flare After Kashmir Massacre
"Any issues between Pakistan and India, we believe can be and should be resolved peacefully through meaningful mutual engagement," said a spokesperson for U.N. Secretary-General António Guterres.
Apr 24, 2025
United Nations Secretary-General António Guterres on Thursday led calls for India and Pakistan to "exercise maximum restraint" as the nuclear-armed neighbors took tit-for-tat measures against each other in the wake of Tuesday's massacre of 26 people in Indian-occupied Kashmir.
Pakistan warned India that it was committing an "act of war" by suspending the landmark Indus Waters Treaty, which allows both countries to share the vital river system's flow. Pakistan announced the suspension of trade and closed its airspace to Indian flights. Both countries closed border ports of entry, canceled visas, and took other measures against each other.
India said it was downgrading relations with Pakistan, whom it blamed for supporting "cross-border terrorism" after gunmen killed 25 Indians and one Nepali and wounded at least 17 others at a popular vacation spot in Pahalgam, Kashmir on Tuesday.
"May sanity prevail between both nations."
A front group of the Pakistan-based militant group Lashkar-e-Taiba claimed responsibility for the attack, which killed mostly tourists.
Pakistani Defense Minister Khawaja Asif countered that his country's government believes "very strongly" that the attack "was a false flag operation."
Speaking Thursday, Stephane Dujarric, Guterres' spokesperson,
said that "we very much appeal to both the governments of Pakistan and India to exercise maximum restraint, and to ensure that the situation and the developments we've seen do not deteriorate any further."
"Any issues between Pakistan and India, we believe can be and should be resolved peacefully through meaningful mutual engagement," he added.
Progressives from both sides of the border echoed calls for restraint.
"We, the people of Kashmir, have already suffered so much over the years—and now, more than ever, we want peace to prevail in our homeland," Kashmiri social activist Jasib Shabir Bhat said on social media Wednesday. "We stand united for peace, for humanity, and for a better future for all."
Pakistani authori and activist Ehtesham Hassan wrote that "as a Pakistani who visited India and received immense love, I am devastated by the news from Pahalgam."
"I wish peace for the common people of India and Pakistan regardless of religion," Hassan added. "May sanity prevail between both nations."
