Seeds of change: The impact of Ethiopia's direct seed marketing approach on smallholders' seed purchases and productivity

American Journal of Agricultural Economics, EarlyView.
Abstract While multiple factors explain low adoption rates of improved varieties by small‐scale farmers in sub‐Saharan Africa, a key supply‐side constraint is the limited availability of seed embodying new traits in the volume, quality, price, and timeliness required by farmers. This constraint is partly attributable to classical failures in the market

Redistributive land reforms, agricultural productivity, and structural change: New cross‐national evidence

American Journal of Agricultural Economics, EarlyView.
Abstract Large‐scale land reforms constitute a substantial redistribution of wealth and reallocation of agricultural land, which is a major form of asset and production input in developing countries. While land redistribution (from the rich to the poor) remains a highly controversial issue, extensive evidence on its effect is limited.

Climate change and perennial crop production: Evidence of yield impact and adaptation in California

American Journal of Agricultural Economics, EarlyView.
Abstract Perennial crops are economically important. They contribute to food security, providing essential nutrients that are often lacking in annual crops, and provide additional environmental benefits compared with annual crops. Despite their importance, empirical research on the impacts of climate change and adaptation on perennial crops remains ...

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

Angewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Effect of Budesonide Nasal Irrigation in Patients With Chronic Rhinosinusitis With Nasal Polyps Without Prior Sinus Surgery: A Randomized, Double‐Blind, Placebo‐Controlled Study

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The indication for nasal irrigation with corticosteroids after sinus surgery in patients with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is well established, as surgery facilitates distribution throughout the sinonasal cavity.

Cost Utility Analysis of Fluticasone Exhalation Delivery System Versus Budesonide Nasal Irrigation for Chronic Rhinosinusitis With Nasal Polyps

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis with nasal polyps (CRSwNP) is managed after sinus surgery with topical corticosteroids. Given limited distribution of nasal steroid sprays, patients have the option of either steroid nasal irrigation (SNI) or exhalation delivery system with fluticasone (EDS‐FLU).
