Examine narratives to end policy deadlock, boost agricultural development in Africa, economists say

Researchers argue that one-sided narratives shape the dichotomy between state-led and market-led approaches to promote agricultural development. A combination of state-led initiatives, donor-funded or market-led approaches, and input subsidy programs can work if there is evidence-based policy learning between both camps.

The complex relationship between deforestation and diet diversity in the Amazon

A study in Peru found that shifting from subsistence farming to commercial agriculture is associated with less diverse diets and reduced access to food among local communities. The expansion of cash crops like palm oil and cocoa has led to simplified production systems and decreased agricultural biodiversity.

Not so robust: robusta coffee more sensitive to warming than previously thought

A new study suggests robusta coffee production decreases by 14% with each 1C increase above a lower-than-once-thought optimal temperature range. The findings contrast with previous estimates and highlight the need for climate adaptation strategies in the coffee industry.

AI goes underground: root crop growth predicted with drone imagery

Researchers have developed a machine learning platform that analyzes high-resolution drone images to predict root crop growth and health. This technology enables scientists to respond quickly to stimuli and breed more drought- and heat-resistant varieties, ultimately improving crop productivity and food security.

An essential sustainable farming practice faces one big limitation: Land to produce seeds

The use of cover crops is increasing globally due to their environmental benefits, such as reducing erosion and improving water quality. However, planting millions of acres of cover crops will require huge extensions of land to produce cover crop seed, posing a limitation to its widespread adoption.

Latin America's livestock sector needs emissions reduction to meet 2030 targets

The study analyzed seven Latin American countries and found that widespread adoption of emission-reduction techniques is necessary to meet target. Researchers highlight barriers to adoption, including lack of access to inputs and information, and propose solutions such as formal systems of replication, subsidies, and technical assistance.

How did an ancient plant from Latin America become Asia's second-most-important cash crop?

Cassava has increased yields dramatically in Asia over the last 50 years, with yields in Vietnam rising from 3 tons per hectare to 20 tons through improved varieties and fertilizer management. Researchers have also developed new varieties for industrial use, such as high-starch cassava ideal for higher latitudes.

Unsustainable food systems: Can we reverse current trends?

A new study found that only international trade has a net positive effect on global food systems sustainability, while population growth, urbanization, and lifestyle change have negative impacts. The study suggests that policymakers need better tools to measure and monitor food system dynamics to make them more sustainable.

Cool beans: A vertical crop fit for Africa's changing climate and nutritional gaps

A new study proposes climbing beans as an intensification solution to increase yield and meet Africa's growing demand for food. Climbing beans can adapt to Africa's future climates in several ways, including intensifying cultivation in high-producing areas.
