Human appropriation of net primary production (HANPP), the aggregate impact of land use on biomass available each year in ecosystems, is a prominent measure of the human domination of the biosphere. We present a comprehensive assessment of global HANPP based on vegetation modeling, agricultural and forestry statistics, and geographical information systems data on land use, land cover, and soil ...

Biomass burning is an essential part of slash-and-burn (S&B) agriculture, which is widely practiced as an important food production system in the tropical mountains of Southeast Asia. S&B agriculture used to be sustainable and carbon neutral; CO2 emissions by biomass burning were balanced with photosynthetic biomass growth, and land use was stable. However, due to drastic land-use change in the...

This paper examines the occurrence and impact of gender discrimination in access to production resources on the income, productivity, and technical efficiency of farmers. Through an empirical investigation of farmers from Koussin-Lélé, a semi-collective irrigated rice scheme in central Benin, we find that female rice farmers are particularly discriminated against with regard to scheme membershi...

— Agriculture made major contributions to China’s growth and poverty reduction, but the literature has rarely focused on the institutional factors that might underpin such structural transformation and productivity. Drawing on an 8-year panel of 1,200 households in six provinces, we find that land tenure insecurity, measured by past land reallocations, discourages households from quitting agric...

Women's land rights are increasingly put forth as a means to promote development by empowering women, increasing productivity, and improving welfare. However, little empirical research has evaluated these claims. This paper uses the 2001 Nepal Demographic and Health Survey to explore whether women's land rights empower women and benefit young children's health in Nepal. The results provide supp...

We examine whether there is empirical support at the household level for theoretical models that suggest that redistribution of productive assets can enhance opportunity and overall growth. To do so, we use a long panel data set for beneficiaries and non-beneficiaries from land reform in the Philippines. Results indicate that land reform resulted in higher investment in physical capital, a grea...

A growing literature is reporting on how the terrestrial carbon cycle is experiencing year-to-year variability because of climate anomalies and trends caused by global change. As CO 2 concentration records in the atmosphere exceed 50 years and as satellite records reach over 30 years in length, we are becoming better able to address carbon cycle variability and trends. Here we review how variab...
