We evaluate the impact of ozone pollution on wheat yields in India and its economic consequences for producers, consumers, and the government. Using an ozone flux–based risk assessment, we find that ambient ozone levels led to a 14.18% average reduction in wheat yields from 2008 to 2012. Irrigated wheat was particularly susceptible to ozone-induced losses, highlighting a potential threat to climate-change adaptation through irrigation expansion. Employing an economic model, we analyze the effects of a "pollution-free" scenario on various factors.

Despite two decades of advancing the understanding of valuing ecosystem services, the global biodiversity crisis continues to face challenges in integrating nature's diverse values into decision-making. Barriers include powerful interests shaped by existing norms and legal rules, such as property rights.

The Values Assessment (VA) of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services shows that while a wide range of valuation methods exist to include nature's values in diverse decision-making contexts, uptake of these methods remains limited. Building on the VA, this paper reviews five critical steps in the evaluation of project or policy proposals that can improve the inclusion of nature’s values in decisions.

Abstract

Background

This study address persistent wealth inequality in anthropometric failure in India by analyzing two rounds of the Indian National Family Health Survey (2019-2021 and 2015-2016) focusing on children aged 0–59 and 6–23 months, reveals a negative wealth gradient for each anthropometric failure measure. Over 60% of the anthropometric failure burden lies in the poorest wealth groups. Notably, even with similar risk factors, children from poorer backgrounds exhibit higher prevalence. Maternal BMI, media exposure, and sanitary facility access are key factors explaining the poor-rich gap.
