Groundnut production functions were estimated from farm survey data in areas with and without shelterbelts. After accounting for land removed from production, groundnut yields increased by 15 percent (12 percent attributed to shelterbelts, three percent attributed to input use changes) in areas with mature shelterbelts. Mature shelterbelts induced estimated annual input savings of 1,074 rupees/ha (435 rupees/acre). High establishment costs and delayed benefits discourage private shelterbelt investments, suggesting a role for public investment. ER -
