The role of intensification in minimizing cropland and slowing deforestation is often disputed. We make a broad distinction between technology-induced market-induced intensification. find evidence at the local level that technical progress few cases may induce land expansion although much depends on where change occurs (near forest frontier or away from it) type market (local global). At global level, technology-driven strongly saving specific regions likely to continue occur. Market-driven...
New estimates of the impacts germplasm improvement in major staple crops between 1965 and 2004 on global land-cover change are presented, based simulations carried out using a economic model (Global Trade Analysis Project Agro-Ecological Zone), multicommodity, multiregional computable general equilibrium linked to spatially explicit database land use. We estimate impact removing gains cereal productivity attributed widespread adoption improved varieties developing countries. Here, several...
Zero-deforestation commitments are a type of voluntary sustainability initiative that companies adopt to signal their intention reduce or eliminate deforestation associated with commodities they produce, trade, and/or sell. Because each company defines its own zero-deforestation commitment goals and implementation mechanisms, content varies widely. This creates challenges for the assessment effectiveness. Here, we develop criteria assess potential effectiveness at reducing within supply...
Zero-deforestation supply chain policies that leverage the market power of commodity buyers to change agricultural producer behavior can reduce forest clearing in regions with rapid expansion and weak governance. Yet leakage-when deforestation is pushed other regions-may dilute global effectiveness regionally successful policies. Here we show domestic leakage offsets 43-50% avoided induced by existing proposed zero-deforestation Brazil's soy sector. However, cross-border insignificant (<3%)...
Abstract Increasing agricultural yields seem an obvious way to satisfy increasing demands for food and fuel while minimizing expansion of agriculture into forest areas; however, influential literature worries that promoting innovation could enhance agriculture's profitability thereby encouraging deforestation. Clarifying the effects technological progress on deforestation is therefore crucial designing effective policy responses challenges faced by global agriculture. In this article we...
This article investigates the relationship between international trade patterns and global distribution of coarse grain production responses to market developments in United States. Our null hypothesis is that world markets are fully integrated, rendering geographic persistence bilateral flows irrelevant response a change U.S. prices. The alternative allows price transmission vary along with intensity competition among countries specific markets. Using data from 1975 2002, we reject...
Abstract Most of the growth in agricultural output last thirty years comes from increases efficiency with which both land and non-land inputs are used. Recent work calls for a better understanding whether this efficiency, known as total factor productivity (TFP), contributes to more sustainable food system. Key is documented phenomenon that, instead saving lands, introduction technologies that improve encourage cropland expansion. We extend results recently published econometric model...
Abstract We estimate the effects of agricultural technological progress on cropland expansion at various geographical resolutions, from country level to world as a whole, while formally accounting for international interdependence national supply responses. Evidence these has thus far been scant, contributing polarized perceptions about potential improving technologies means slow down deforestation. find that, in most countries world, growth total factor productivity (TFP) is either...
Abstract This article explores the impacts of China's growth in international markets agricultural products along two dimensions: food price inflation and export other developing countries. imports vegetable oils have grown dramatically over last decade, linking economic to recent increases global prices. If China is a source inflation, exporting countries will benefit whether they sell directly or not. These direct indirect linkages are explored using short‐run, partial‐equilibrium model...
We discuss an on-line tool that facilitates access to the large collection of climate impacts on crop yields produced by Agricultural Model Intercomparison and Improvement Project. This comprises output seven models which were run a global grid using data from five different general circulation under current set representative pathways. The this modeling endeavor consists more than 36,000 publicly available grids at spatial resolution one half degree. offer flexible ways aggregate these...
Computable General Equilibrium (CGE) models incorporating firm heterogeneity can overcome the shortcomings of traditional Armington-based in explaining changes productivity and variety wake reduced trade costs. In this paper, we present a new modeling framework where theory Melitz is introduced into Global Trade Analysis Project (GTAP) model calibrated to GTAP 8 Data Base. The mechanisms are demonstrated stylized scenario with 3 regions (USA, Japan Rest World) 2 sectors (manufacturing...
Abstract This article examines how trade policies can mitigate the impact of frictions that worsen food price spikes when supply shocks are correlated across trading partners. El Niño Southern Oscillation (ENSO) offers a natural experiment global climate phenomenon induces weather correlation continents. Gravity‐derived maize prices in southern and eastern Africa increase significantly response to extremes. Eliminating border friction reduces self‐sufficiency magnitude Niño‐driven increases....
Do food imports increase the variability of domestic prices? The answer to this question depends on whether foreign production is more volatile than production. If are likely destabilize prices, storing crops for future consumption may prove an appealing strategy cope with adverse supply effects a unstable climate. Unfortunately, public storage has proven be unsustainable due high costs carrying crop inventories over time and inability policy planners correctly forecast changes in supply....
China's export expansion is commonly associated with lower global manufacturing prices. For most countries, prices heighten competition but also allow importing a cheaper and wider set of inputs consumer goods. This paper investigates the balance these two forces in Kenya, Mauritius Southern Africa Customs Union, largest exporters manufactured goods sub-Saharan Africa.

Agriculture will play a central role in meeting greenhouse gas (GHG) emission targets, as the sector currently contributes ∼22% of global emissions. Because emissions are directly tied to resources employed farm production, such land, fertilizer, and ruminant animals, productivity input use tends be inversely related intensity. We review evidence on how gains agriculture have contributed historical changes emissions, they affect land both locally globally, investments research development...
Simultaneous worldwide crop failures stemming from a more unstable climate may reduce the scope for international trade to compensate food shortages and stabilize prices across various regions of world. Understanding effects changes in productivity on global markets requires knowledge about extent which yields be systematically related producing consuming centers. This short communication contributes this by investigating potential strength two key sources supply risks maize markets: yield...
Land supply elasticities determine the rates of land conversion in global policy models. However, they are only available for few countries world. Therefore, analysts seeking to improve spatial resolution their models forced impose regionally homogeneous parameters over highly heterogeneous regions. This article estimates spatially explicit using gridded data American continent. These reasonably reproduce changes use observed at different levels geographical aggregation across Plugging our a...
Abstract In 2016, the U.S. launched a trade dispute against China at World Trade Organization, arguing that has been restricting its grain imports via tariff quota administration. Despite sharp criticisms by U.S., extent to which were restricted in remains largely unknown, primarily due China's import behaviors are still under‐researched. The export sector might actually gain little from liberalization short run, since become less dependent on through pursuit of diversification. this...
We estimate the impact of tariffs faced by US agricultural exports on farmland rents. The localized tariff is determined average across trading partners for crops produced within county. utilize shift-share designs to avoid endogeneity concerns that arise because factors affecting rents could also affect trade flows and cropping patterns. Using county-level data from 2008 2017, we find a one percentage point decrease in increases 3%–6%. 2018 Chinese retaliatory would have decreased about 3%...
