Since the late 1950s, the United States has experienced an increase in heavy precipitation driven by human-caused climate change, which allows the atmosphere to hold more moisture. These events, exacerbated by aging infrastructure and non-permeable land surfaces, increase the risk of urban and flash floods, damage agriculture through soil erosion and crop loss, and disrupt transportation systems.

African cities face increasing water insecurity driven by climate change and rapid urbanization, which current governance and financial models cannot address. The report argues for a transition to water-resilient systems through four strategic pathways: risk-informed land management, equitable access for vulnerable populations, institutional innovation, and aligned sectoral investments.

The document addresses the environmental risks associated with the unprecedented expansion of the U.S. corn ethanol industry following the Energy Policy Act of 2005. It argues that policy focus should shift from industry expansion to an evolution that prioritizes energy security and environmental benefits, offering specific farm policy recommendations to manage soil, water, and greenhouse gas impacts.

The analysis finds that Indonesia's existing land-use and energy policies are insufficient to meet its unconditional 29% emissions reduction target by 2030, but strengthened policies could surpass this goal. The forest moratorium is identified as the policy with the highest mitigation potential, while the energy sector is projected to become the dominant source of emissions by 2026–27, necessitating urgent shifts toward renewable energy and conservation to avoid carbon lock-in.

The document proposes a 'working forest' model for the southern United States, where public entities acquire land or development rights to generate revenue from sustainable timber, recreation, and ecosystem services. This approach is presented as a more cost-effective alternative to traditional conservation programs, with potential for local management via citizen advisory boards and financing through public bonds or taxes.

The report warns that increasing global demand for land-based products is underappreciated in current climate strategies, potentially leading to policies that increase emissions. It projects significant land conversion by 2050 and advocates for a strategy of producing more on existing land, protecting ecosystems, reducing demand for land-intensive products, and restoring native habitats.

The WRI Results Framework establishes a structured system to plan and evaluate programmatic progress across three primary human systems: food, land & water; energy; and cities. It sets specific global targets for 2030 and WRI intervention targets for 2027, focusing on outcomes such as reducing agricultural land demand by 100 Mha, increasing the share of zero-carbon electricity by 9% in target geographies, and improving urban climate resilience. The framework integrates Sustainable Development Goals (SDGs) and utilizes a tiered approach of global, intervention, and country-specific targets, supported by impact indicators for people, nature, and climate.

The WRI Ross Center for Sustainable Cities employs an integrated approach combining data-driven research and long-term city partnerships to address urban challenges in land use, mobility, and energy efficiency. The organization focuses on the global south, implementing projects such as low-emission zones in Beijing, sustainable housing standards in Brazil, and last-mile mobility solutions in Bengaluru. Its strategy emphasizes scaling road-tested solutions through national policy guidance and global coalitions to help cities decarbonize and improve equitable access to core services.

The document outlines the challenges of modern urbanization, particularly in the global South, where rapid population growth coincides with low per capita resources. It argues that providing equitable access to core services—such as housing, water, sanitation, energy, and transportation—is essential to avoid cycles of poverty and environmental degradation and to unlock economic productivity.

The document argues that seaweed (macroalgae) is a promising nutritional supplement for pigs, offering significant health benefits for weaning piglets, sows, and boars. It highlights seaweed's ability to regulate gut microbiota, reduce pathogenic bacteria, and improve growth performance. Additionally, the text positions seaweed as a more sustainable alternative to traditional feed crops like corn and soybean meal because its cultivation does not require fresh water, arable land, pesticides, or external fertilizers.

The guide highlights that approximately 63 million tons of food are wasted annually in the United States, primarily in supermarkets, restaurants, and home kitchens. It advocates for three main actions to reduce environmental impact: shopping prudently through menu planning and freezing leftovers, increasing the consumption of fruits and vegetables to lower greenhouse gas emissions and resource use, and composting food scraps to avoid the emission of methane in landfills, which traps 24 times more heat than carbon dioxide.

The document outlines the environmental and financial costs of food waste in the US, noting that nearly half of all waste occurs in homes. It provides actionable advice on food preservation, such as freezing and reinvigorating produce, and encourages users to challenge 'best before' labels and support legislative action in Congress.

The report advocates for 'controlled intensification' in shrimp aquaculture to replace unsustainable extensive farming. It proposes three accelerators—widespread technology use, intentional capital direction, and democratization of knowledge—to achieve conversion-free production and resource efficiency. The document outlines a three-phase innovation pathway (Predict and Control, Optimize, and Breakthrough) and emphasizes the role of long-term contracts and impact investing in scaling these systems.

The report analyzes the relationship between production intensity and resource use in shrimp farming across Thailand and Vietnam. It argues that intensification—increasing output per unit area—reduces the land, water, and energy footprint per ton of shrimp, thereby offering both economic benefits to farmers and environmental protection for coastal habitats. The study highlights the Feed Conversion Ratio (FCR) as a critical indicator of both economic cost and environmental impact, particularly regarding the use of wild fish in feed. It concludes that responsible intensification is the most viable path to meeting growing consumer demand without further converting biodiverse coastal ecosystems into farms.
