Sparing or sharing land? Views from agricultural scientists
TLDR
In this paper, the authors pointed out the limitations of the land sparing/sharing framework: (1) the reliance on yield-density relationships that focus on trade-offs and overlook synergies between agriculture and biodiversity, and (2) the overemphasis on crop yield, neglecting other metrics of agricultural performance which may be more important to local farmers, and more strongly associated with positive biodiversity outcomes.About:

Implications of land sparing and sharing for maintaining regional ecosystem services: An empirical study from a suitable area for agricultural production in China.
Xiaoling Zhang,Xiaobin Jin,Xinyuan Liang,Jie Ren,Bo Han,Jingping Liu,Yeting Fan,Yinkang Zhou +7 more
TL;DR: In this paper , a spatial classification model for land use was built based on land sparing and sharing, and an empirical analysis was carried out with the coastal agricultural production area of Maoming City, Guangdong Province.
Journal ArticleDOI
Biodiversity and yield trade-offs for organic farming.
Shanxing Gong,Jenny A. Hodgson,Teja Tscharntke,Yunhui Liu,Wopke Van der Werf,Péter Batáry,Johannes M. H. Knops,Yi’nan Zou +7 more
TL;DR: In this article , the authors conducted a meta-analysis quantifying the trade-off between biodiversity and yield, comparing conventional and organic farming, and developed a compatibility index to assess whether biodiversity gains from organic farming exceed yield losses.

Dietary quality and tree cover in Africa
TL;DR: The relationship between forests and human nutrition is not yet well understood as mentioned in this paper, and a better understanding of this relationship is vital at a time when the majority of new land for agriculture is being cleared from forests.
Journal ArticleDOI
Sharing land via keystone structure: Retaining naturally regenerated trees may efficiently benefit birds in plantations.
TL;DR: In this article , a hierarchical community model was developed to assess the effect of retaining a small amount of broad-leaved trees on the abundance and space-use of conifer plantations.

Commodity crops in biodiversity-rich production landscapes: Friends or foes? The example of cotton in the Mid Zambezi Valley, Zimbabwe
TL;DR: In the Mid Zambezi valley, Zimbabwe, which is home to many emblematic African mammals, cotton production has historically been a major driver of land cover change as discussed by the authors , and the linkages between the profitability of cotton and land use changes in this multifunctional landscape.

TL;DR: Identifying and quantifying planetary boundaries that must not be transgressed could help prevent human activities from causing unacceptable environmental change, argue Johan Rockstrom and colleagues.

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.

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.

TL;DR: In this article, the authors proposed a new approach to global sustainability in which they define planetary boundaries within which they expect that humanity can operate safely. But the proposed concept of "planetary boundaries" lays the groundwork for shifting our approach to governance and management, away from the essentially sectoral analyses of limits to growth aimed at minimizing negative externalities, toward the estimation of the safe space for human development.
