As primeiras décadas do século XXI têm sido marcadas por uma corrida global por terras, desencadeada pelas crises agroalimentar, energética, climática e econômico-financeira. O objetivo deste artigo é analisar se os Estados Unidos estiveram na rota dessa corrida. Para tanto, examinamos dados do Departamento de Agricultura dos Estados Unidos (United States Department of Agriculture – USDA) e bibliografia especializada, e identificamos que a porção de terras em mãos estrangeiras dobrou entre 2004 e 2014.

Constrained access to land is increasingly recognized as a problem impeding rural household welfare in densely populated areas of Africa. This study utilizes household and parcel level data from rural Kenya to explore the linkage between land access and food security. We find that a 10% increase in operated land size would increase household total food consumption per capita, cereal consumption per capita, non-cereal consumption, and home produced food consumption by 2.6%, 2.1%, 2.7% and 5.4%, respectively.

Agriculture influences and shapes the world’s ecosystems, but not always in a positive way. More than 2.5 billion people are globally involved as stewards of land and water ecosystems that constitute the natural resource base for feeding the current and future world population. Yet, conventional agronomic interventions based on ‘hard’ agricultural engineering compromise various eco-services that are required for sustainable agricultural development.

Volume 10 Issue 2
Peer-reviewed publicationFebruary, 2021United States of AmericaFarmland fragmentation and farmland consolidation are two sides of the same coin paradoxically viewed as farmland management tools. While there is a vast body of literature addressing the connections between farmland fragmentation and farmland consolidation on the one hand and agriculture production and crops diversification on the other hand, their relationship with variations in food security is still under-explored. This challenges policy makers about whether and how to devise policies in favor of fragmentation conservation or defragmentation.

Peer-reviewed publicationFebruary, 2021Central African Republic, China, India, British Indian Ocean Territory, Russia, United States of America, EuropeThe issue of food security has been widely studied by the international community. To reveal the research situation as it pertains to food security objectively, this paper comprehensively utilizes bibliometrics techniques (i.e., Bibliometrix, VOSviewer, and CiteSpace) to explore the research status and development trends in the area of food security. The results show that: (1) food security research has shown an increasing trend during the past 30 years.

Land Use Policy Volume 67
Peer-reviewed publicationSeptember, 2017Norway, United States of AmericaWith international food price shocks in 2008 and 2011, food security became a political priority in many countries. In addition, some politicians have recently adopted a more nationalistic stance. Against that background, this paper critically investigates the prospects of increased food production within a national context. We use a small, high-income country, Norway, as an empirical case. In 2012, the government set a goal of increasing agricultural food production by 20% by 2030. We ask: 1) How has food production in Norway developed before and after the goal was set?

Land Use Policy Volume 76
Peer-reviewed publicationJuly, 2018United Kingdom, United States of AmericaWe assess the production impacts of a 100% conversion to organic agriculture in England and Wales using a large-scale linear programming model. The model includes a range of typical farm structures, scaled up across the available land area, with the objective of maximising food production. The effects of soil and rainfall, nitrogen (N) supply/offtake and livestock feed demand are accounted for. Results reveal major reductions in wheat and barley production, whilst the production of minor cereals such as oats and rye increase.

Peer-reviewed publicationDecember, 2020China, Russia, United States of AmericaUnderstanding the impact of changes in cultivated land in terms of structure, distribution, and quantity on grain production potential (GPP) is essential for a sustainable land utilization strategy and food security. Cultivated land balance (CLB), as a critical policy aiming at protecting farmland in China, has greatly restricted the loss of cultivated land. However, changes in cultivated land were largely generated due to the land-use activities led by the CLB policy.

Peer-reviewed publicationDecember, 2020Canada, NorwayClimate change driven food insecurity has emerged as a topic of special concern in the Canadian Arctic. Inuit communities in this region rely heavily on subsistence; however, access to traditional food sources may have been compromised due to climate change. Drawing from a total of 25 interviews among Inuit elders and experienced hunters from Cambridge Bay and Kugluktuk in Nunavut, Canada, this research examines how climate change is impacting food sovereignty and health. Our results show that reports of food insecurity were more pronounced in Kugluktuk than Cambridge Bay.

Peer-reviewed publicationNovember, 2020United States of AmericaGreen infrastructure (GI), as a concept and as a tool for environmental land-use planning at various scales, has burst onto the academic, political, and policy-making scenes in the last two decades. This tool, associated with strategic planning, offers integrated solutions for improving the ecological connectivity and urban resilience of open spaces, especially those affected by processes of urban sprawl, the abandonment of agriculture, and the territorial fragmentation of habitats and traditional agricultural landscapes.
