Closing yield gaps in South Asian wheat production (Bihar, India and Terai of Nepal)
… the Eastern Indo-Gangetic Plain. Closing wheat yield gaps in this region through agronomic practices currently available to farmers can contribute to a more secure future in this region. In Nepal and Bihar, India, a set of complementary management practices were associated with higher yields, …

Food demand and supply under global change
… impairs the agriculture sector, reducing crop yields namely due to soil degradation, water scarcity, and climate change. However, this is a more complex issue than it appears. Crop yields can be increased by use of agrochemicals and fertilizers which are mainly produced by fossil energy. This …

Brazil’s Soy Moratorium: Current Expansion Capacities, Extension to the Cerrado, and Increasing Compliant Production
… onto all Soy Moratorium-eligible land, closing yield gaps on current lands, and introducing integrated-crop-livestock systems with soy (ICLS) onto established pasture. We find 18.0 Mha of additional remaining eligible area in the Amazon and a hypothetical 67.9 Mha in the Cerrado, of which 81.0% …

Agricultural productivity and climate shocks in developing countries
… data and crop simulations to decompose farmers’ yield gaps to measure how much of the gap is driven by risk aversion. In the third paper, I study the impact of a demand shock on agricultural inputs markets in Zambia.

The Evaluation of Root System Architecture (RSA) As A New Breeding Target for Climate-Resilient Winter Wheat (Tritium aestivum L.)
Crop yields are expected to face more threatening circumstances due to ongoing climatic and environmental change. The continued sustainability of crop production will depend on genetic capacity of crops to adapt to increased biotic and abiotic barriers induced by climate change. Historically, …

A remote sensing assessment of irrigation land use land cover change in the Sokoto Rima River Basin, Nigeria
… in the Sokoto Rima River Basin using the ground yield and remote sensing data. Decadal land use land cover (LU/LC) change detection was conducted using remotely sensed data from Landsat 4,5,7 ETM for 1988, 1998 and Landsat 8 OLI for 2018 using a digital classification and a cloud-based …

Study of nitrogen limitation and seed nitrogen sources for historical and modern genotypes in soybean
Soybean [Glycine max (L.) Merr.] yields have continuously increased over time. Seed yields are determined by the genotype, environment, and management practices (G × E × M) interaction. Closing yield gaps require a continuous improvement in the use of the available resources, which must be attained …

Essays on innovation in the U.S. corn and soybean seeds
… held by farmers. The second essay examines the yield gain from GE maize adoption and uses it as a yardstick to gauge the scope of innovation required to adapt to anticipated damage from future climate change. The research draws on the observed county-level maize yields and historical weather …
