Did the Indian Green Revolution Change the Farm Size–Productivity Relationship?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We examine the relationship between farm size and productivity during India's Green Revolution, a period of rapid technological transformation. Using a unique panel of over 5000 Indian farm households that spans the Green Revolution (1971–1999), we show that the classic (linear) inverse farm size–productivity relationship gradually evolved ...

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...

Temperature and Farm Labor in Nigeria
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

‘Jivanam jivinam jivaha’ is a Sanskrit shlok, cited in an Ayurveda text ‘Bhavaprakash,’ which translates to ‘water is life to creatures.’ Water has always been an important source of life on Earth. However, today’s water crisis is gripping. In July 2019, Chennai witnessed an acute water crisis, after one of the main reservoirs completely dried up.

This chapter explores how water has been put to use to serve communities. Among the myriad uses that water has served, irrigation was certainly one of the earliest and most important, particularly to communities in arid regions. Indeed, the long-term viability of these communities depended on maintaining irrigation systems in the face of multiple ...

Water Production Reaction on Rh(110)
Journal of the American Chemical Society, 2005By means of scanning tunneling microscopy and density functional theory calculations, we studied the water formation reaction on the Rh(110) surface when exposing the (2 x 1)p2mg-O structure to molecular hydrogen, characterizing each of the structures that form on the surface during the reaction.

Optimised product and water recovery from batch-production rinsing waters
Waste Management, 2000Abstract Product concentrate can be recovered from rinsing waters [cleaning in place (CIP)] of surfactant and detergent batch production processes by using ultrafiltration and nanofiltration membranes. The problem in designing a separation process for the rinsing water is that the different compositions of the CIP-batches result in different ...
