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

TL;DR: It is shown that tremendous progress could be made by halting agricultural expansion, closing ‘yield gaps’ on underperforming lands, increasing cropping efficiency, shifting diets and reducing waste, which could double food production while greatly reducing the environmental impacts of agriculture.

Global food demand and the sustainable intensification of agriculture
TL;DR: Per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960 and forecasts a 100–110% increase in global crop demand from 2005 to 2050.

Landscape perspectives on agricultural intensification and biodiversity – ecosystem service management
TL;DR: In this article, the negative and positive effects of agricultural land use for the conservation of biodiversity, and its relation to ecosystem services, need a landscape perspective, which is difficult to be found in the literature.
REVIEWS AND SYNTHESES Landscape perspectives on agricultural intensification and biodiversity - ecosystem service management
TL;DR: In this article, the negative and positive effects of agricultural land use for the conservation of biodiversity, and its relation to ecosystem services, need a landscape perspective, which may compensate for local highintensity management.

The global distribution of clinical episodes of Plasmodium falciparum malaria
TL;DR: It is estimated that there were 515 (range 300–660) million episodes of clinical P. falciparum malaria in 2002, up to 50% higher than those reported by the World Health Organization and 200% higher for areas outside Africa, reflecting the WHO's reliance upon passive national reporting for these countries.

PHOSPHORUS IN THE ENVIRONMENT: Natural Flows and Human Interferences
TL;DR: In this article, the global mobilization of the element, a part of the grand geotectonic denudation-uplift cycle, is slow and low solubility of phosphates and their rapid transformation to insoluble forms make the element commonly the growth-limiting nutrient, particularly in aquatic ecosystems.

Legume-based cropping systems have reduced carbon and nitrogen losses
TL;DR: In this paper, the authors report the net balances of carbon and nitrogen from a 15-year study in which three distinct maize/soybean agroecosystems are compared.

TL;DR: The process of economic valuation could greatly improve stewardship of ecosystems and is now being realized with innovative financial instruments and institutional arrangements.

Nitrogen in crop production: An account of global flows
TL;DR: In this article, it was shown that despite some significant local and regional losses, the world's agricultural land accumulates N. The best evidence suggests that in spite of some significant localized losses, agricultural land still accumulates about 85% of the reactive N in the world.
