Delayed monsoon, irrigation and crop yields

Submitted by Ishita Datta on
EfD Authors:

Most of the empirical literature assessing the impacts of climate change on agriculture has modeled crop yields as a function of the levels or deviations in the growing-period rainfall. However, an aspect that has received little attention in the empirical literature relates to the relationship between the timing of monsoon rains and crop yields. Using a pan-India district-level panel dataset for 50 years, this article investigates two interrelated issues critical to understanding the impacts of weather-induced agricultural risks and their management.

Gender and mechanization: Evidence from Indian agriculture

Submitted by Ishita Datta on

Technological change in production processes with gendered division of labor across tasks, such as agriculture, can have a differential impact on women's and men's labor. Using exogenous variation in the extent of loamy soil, which is more amenable to deep tillage than clayey soil and therefore more likely to see adoption of tractor-driven equipment for primary tilling, we show that mechanization led to significantly greater decline in women's than men's labor on Indian farms during 1999–2011. Reduced demand for labor in weeding, a task often undertaken by women, explains our findings.

Assessing the costs of ozone pollution in India for wheat producers, consumers, and government food welfare policies

EfD Authors:

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.

Overview of known plastic packaging-associated chemicals and their hazards

Global plastics production has reached 380 million metric tons in 2015, with around 40% used for packaging. Plastic packaging is diverse and made of multiple polymers and numerous additives, along with other components, such as adhesives or coatings.

Market-Based Instruments for Managing Hazardous Chemicals: A Review of the Literature and Future Research Agenda

Submitted by Mark Senanu Ku… on

We take stock of the lessons learned from using market-based instruments in chemicals management and discuss the potential for increased use of risk-based taxation in the management of pesticides and other hazardous chemicals. Many chemical substances cause significant diffuse emissions when emitted over wide areas at individually low concentrations. These emissions are typically very difficult and costly to control. The targeted chemical may exist in many products as well as in a wide variety of end uses.

Circular economy could expose children to hazardous phthalates and chlorinated paraffins via old toys and childcare articles

Submitted by Mark Senanu Ku… on

The European waste framework directive encourages reuse, refurbishment and recycling of products and materials in order to reduce plastic waste. However, thousands of chemicals are used in plastic materials. Many of these are potentially toxic, and may cause hormonal and developmental disruption in children. This includes phthalates and short chain chlorinated paraffins, which are used as plasticizers and flame-retardants. European legal frameworks regulate the amounts of these substances in toys in an effort to protect children's health and safety.

REACH authorisation and the substitution of hazardous chemicals: The case of trichloroethylene

Submitted by Mark Senanu Ku… on

Through a survey with European companies and expert interviews we study how REACH authorisation affects the phase-out of hazardous chemicals focusing on trichloroethylene, a well-studied solvent used in metal parts cleaning. We find that most of the firms have substituted trichloroethylene by perchloroethylene, which has similar chemical characteristics. This allows them to continue to use the same machines and routines at low costs.

What drives the substitution of hazardous flame retardants in electronic appliances in Sweden?

Submitted by Mark Senanu Ku… on

Chemical substitution can mitigate risks from chemical substances for individuals and the environment. This study investigates the preferences of companies regarding the adoption of safer alternatives to hazardous flame retardants in electronic appliances in Sweden.
