Distinct response of gross primary productivity in five terrestrial biomes to precipitation variability

Communications Earth & Environment, 2020
Climate change will impact precipitation variability, potentially accelerating climate-terrestrial carbon feedbacks. However, the response of ecosystems to precipitation variability is difficult to constrain due to myriad physiological and abiotic ...

Multisectoral Convergence of Food, Nutrition and Sanitation Programs for Child Health: Evidence From Country‐Level Programs in India

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This paper underscores the critical role of multisectoral convergence in enhancing child health, particularly in addressing anemia, a micronutrient deficiency linked to both diet and sanitation. We explore how the integration of nationwide food and nutrition programs with sanitation initiatives impacts anemia in Indian children under three ...

Potential gross primary productivity of terrestrial vegetation from 1982–1990

Geophysical Research Letters, 1995
Monthly mean global green leaf area and photosynthetically active radiation estimated from observations made from several geostationary and polar orbiting satellites were used to estimate potential, (i.e., unstressed) gross primary productivity of terrestrial vegetation from 1982 to 1990. Mean annual gross primary productivity was estimated to be about

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
