A new study from the University of Göttingen reveals that Fairtrade certification benefits employees in agricultural cooperatives, but not smallholder farm workers who are often disadvantaged. The study found no effects on the livelihoods of farmworkers despite improved wages and labor conditions for cooperative employees.
The study found that expansion poses a particularly serious threat to biodiversity in the tropics, while intensification primarily threatens biodiversity in Sub-Saharan Africa. Global agricultural production must increase to meet demand, but this comes at the cost of biodiversity.
Research from the University of East Anglia finds that women's agricultural work has a negative impact on household nutrition, particularly due to reduced time for care work and seasonal energy deficits. This can lead to poor child- and household-level nutrition outcomes.
A new study found that post-Soviet changes in food systems resulted in a net emissions reduction of 7.61 gigatons of carbon dioxide equivalents from 1991 to 2011. This decrease was mainly due to the decline in domestic livestock production and soil organic carbon sequestration on abandoned cropland, particularly in Russia and Kazakhstan.
A new study investigates the use of multiple fungal biopesticides to prevent uniform evolutionary response and promote sustainable control. The project aims to make agricultural landscapes more diverse, allowing for longer-term use of biopesticides without consistent resistance evolution.
Agricultural pesticides reduced aquatic insect biodiversity but increased mosquito density, particularly for the pesticide-resistant Wyeomyia abebala. Pesticide use led to the loss of predators, allowing these mosquitoes to colonize habitats without competitors.
A recent study found that organic animal farms increase bird numbers in agricultural environments, contrary to other environmental subsidies. The proximity of organic farms was particularly beneficial for insectivore birds.

This approach enables the highest species diversity, promotes ecosystem services such as pollination and biological pest control, and benefits people.
A study found that climate change may lead to increased fertility due to reduced resources for education, as people allocate time and money for child-rearing. The researchers used a quantitative model to examine the economic channels through which climate change affects fertility, finding that it worsens inequalities in richer countries.
A field experiment in Uganda found that raising tenants' share of crops from 50% to 75% can increase agricultural output by 60%, thanks to higher investment and risk-taking. The change also led to a sharp gain in overall welfare for tenants, but a 20% drop in landlords' income.
Researchers discovered that small farm dams in Canada are unexpectedly absorbing nitrous oxide, a potent greenhouse gas. This finding suggests that these nutrient-rich waterbodies could be used to reduce agricultural emissions.

A study by University of Toronto researchers found that four crops (soybeans, wheat, rice, and corn) now dominate globally, with only 152 out of 153 main crops being grown. This trend has implications for regional food sovereignty, ecological resilience, and pest/disease management.
A new study by Graziano Ceddia reveals that greater inequality increases deforestation in Latin America, while less inequality better protects forests. Increasing agricultural productivity can help reduce pressure on remaining forests, but it also incentivizes the conversion of more forests to cropland.
A new paper by Yale researchers confirms that increasing soil organic carbon boosts yields until concentrations reach about 2 percent, after which returns diminish. Roughly two-thirds of agricultural soils dedicated to maize and wheat fall below this threshold, suggesting vast potential for policies promoting increased SOM.
Researchers estimate that saturated buffers, vegetated strips of land between tile-drained fields and waterways, could reduce agricultural drainage nitrogen by 5 to 10 percent. This approach is inexpensive and can be easily integrated with farming practices.

Researchers analyzed animal bones from 90 archaeological sites in Ireland and discovered an increase in deforestation and agriculture during the Bronze Age.
Researchers found that fawn survival is higher in landscapes with mixed forest and agricultural cover, but human-caused mortalities are greater. The study suggests that efforts to alter fawn survival may be challenging due to predation, and that reducing antlerless harvests may be more effective.
Increasing temperatures and mercury pollution shift female-to-male ratios in snapping turtles, favoring male offspring in agricultural habitats. Field experiments found that temperature profiles and soil moisture content influenced sex determination, while mercury levels correlated with the development of more male offspring.
