A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society.Abstract:
A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.read more

Plant breeding and farmer participation.
TL;DR: In this paper, the authors provide a comprehensive description and assessment of the use of participatory plant breeding in developing countries, with the hope that they all will find a common ground to discuss ways in which plant breeding can be beneficial to all and contribute to alleviate poverty.

Land use options for staying within the Planetary Boundaries – Synergies and trade-offs between global and local sustainability goals
Vera Heck,Vera Heck,Vera Heck,Holger Hoff,Holger Hoff,Stefan Wirsenius,Carsten Meyer,Holger Kreft +7 more
TL;DR: In this paper, the authors develop and assess alternative global land use patterns guided by the Planetary Boundaries framework, to quantify land use opportunities for staying within the safe environmental operating space, and determine the potential upper bounds of improved terrestrial carbon storage and of biodiversity conservation, while also meeting the planetary Boundaries of land and water use and ensuring improved food supply for a population of 9 billion people.
Journal ArticleDOI
Agri-food markets towards sustainable patterns
TL;DR: Based on a critical review of the existing international literature, the authors seeks to understand the evolutionary paths of sustainability issues within agri-food markets by analyzing their drivers and trends, focusing mainly on the relationship between markets, trade, food and nutrition security.

Luxury phosphorus uptake in microalgae
Alexei Solovchenko,Tatiana Ismagulova,A. A. Lukyanov,S. G. Vasilieva,I. V. Konyukhov,Sergei I. Pogosyan,Elena Lobakova,Olga Gorelova +7 more
TL;DR: The knowledge of luxury P uptake originating from classical phycological and biochemical methods is confronted with the recently obtained understanding of molecular mechanisms of P transport to the cell, polyphosphate biosynthesis, regulation, and genetic control of these processes.

Suppression of the invasive plant mile-a-minute (Mikania micrantha) by local crop sweet potato (Ipomoea batatas) by means of higher growth rate and competition for soil nutrients
Shicai Shen,Gaofeng Xu,David R. Clements,Guimei Jin,Aidong Chen,Fudou Zhang,Hisashi Kato-Noguchi +6 more
TL;DR: Planting sweet potato is a promising technique for reducing infestations of mile-a-minute, providing weed management benefits and economic returns from harvest of sweet potatoes, and the potential value of replacement control methods which may apply to other crop-weed systems or invaded natural ecosystems are shown.

Climate change 2001: the scientific basis
John Theodore Houghton,Y. Ding,David John Griggs,M. Noguer,P. J. van der Linden,X. Dai,K. Maskell,C. A. Johnson +7 more
TL;DR: In this article, the authors present an overview of the climate system and its dynamics, including observed climate variability and change, the carbon cycle, atmospheric chemistry and greenhouse gases, and their direct and indirect effects.

Human Domination of Earth's Ecosystems
TL;DR: Human alteration of Earth is substantial and growing as discussed by the authors, between one-third and one-half of the land surface has been transformed by human action; the carbon dioxide concentration in the atmosphere has increased by nearly 30 percent since the beginning of the Industrial Revolution; more atmospheric nitrogen is fixed by humanity than by all natural terrestrial sources combined; more than half of all accessible surface fresh water is put to use by humanity; and about one-quarter of the bird species on Earth have been driven to extinction.

Human alteration of the global nitrogen cycle: sources and consequences
Peter M. Vitousek,John D. Aber,Robert W. Howarth,Gene E. Likens,Pamela A. Matson,David W. Schindler,William H. Schlesinger,David Tilman +7 more
TL;DR: In this article, a review of available scientific evidence shows that human alterations of the nitrogen cycle have approximately doubled the rate of nitrogen input into the terrestrial nitrogen cycle, with these rates still increasing; increased concentrations of the potent greenhouse gas N 2O globally, and increased concentration of other oxides of nitrogen that drive the formation of photochemical smog over large regions of Earth.

Nonpoint pollution of surface waters with phosphorus and nitrogen
Stephen R. Carpenter,Nina F. Caraco,David L. Correll,Robert W. Howarth,Andrew N. Sharpley,Val H. Smith +5 more
TL;DR: In this article, a review of the available scientific information, they are confident that nonpoint pollution of surface waters with P and N could be reduced by reducing surplus nutrient flows in agricultural systems and processes, reducing agricultural and urban runoff by diverse methods, and reducing N emissions from fossil fuel burning, but rates of recovery are highly variable among water bodies.
