TL;DR: Institutions with broad authority and a global perspective are needed to create a system with incentives for conservation.
Abstract: Marine resource exploitation can deplete stocks faster than regulatory agencies can respond. Institutions with broad authority and a global perspective are needed to create a system with incentives for conservation.

TL;DR: The results show that self-organized vegetation patterns observed in arid ecosystems might all be the result of spatial self-organization, caused by one single mechanism: water infiltrates faster into vegetated ground than into bare soil, leading to net displacement of surface water to vegetated patches.
Abstract: Scientists are still searching for possible unifying mechanisms
to explain this range of spatial patterns (Tongway
and Ludwig 2001), and an important question of this research
is whether this range is the result of preexisting
environmental heterogeneity, the result of spatial selforganization,
or both (Klausmeier 1999; Couteron and
Lejeune 2001; HilleRisLambers et al. 2001; Von Hardenberg
et al. 2001). Here, we contribute to the ongoing debate
about vegetation pattern formation in arid ecosystems
by presenting novel, spatially explicit model analyses and
results, extending on the work of HilleRisLambers et al.
(2001). Our results show that these different vegetation
patterns observed in arid ecosystems might all be the result
of spatial self-organization, caused by one single mechanism:
water infiltrates faster into vegetated ground than
into bare soil, leading to net displacement of surface water
to vegetated patches. This model differs from earlier model
results (Klausmeier 1999; Couteron and Lejeune 2001;
HilleRisLambers et al. 2001; Von Hardenberg et al. 2001) primarily in two ways: it is fully mechanistic, and it treats
the lateral flow of water above and below the soil as separate,
not independent, variables. Although the current
model greatly simplifies the biophysics of arid systems, it
can reproduce the whole range of distinctive vegetation
patterns as observed in arid ecosystems, indicating that
the proposed mechanism might be generally applicable.
We further show that self-organized vegetation patterns
can persist far into regions of high aridity, where plants
would become extinct if homogeneously distributed,
pointing to the importance of this mechanism for maintaining
productivity of arid ecosystems (Noy-Meir 1973).
Our analyses are based on the model first developed in
HilleRisLambers et al. (2001)

TL;DR: The magnitude of contamination, regulatory compliance and annual loadings of soils with copper (Cu), zinc (Zn), cadmium (Cd), nickel (Ni), chromium (Cr) and lead (Pb) were determined at three sites in Harare where wastewater was used to irrigate vegetable gardens for at least 10 years.

TL;DR: The first spatially explicit, multielement (N, P, and C), multiform (dissolved inorganic: DIN, DIP; dissolved organic: DOC, DON, DOP; and particulate: POC, PN, PP) predictive model system of river nutrient export from watersheds (Global Nutrient export from Watersheds (NEWS)) is presented in this paper.
Abstract: [1] An overview of the first spatially explicit, multielement (N, P, and C), multiform (dissolved inorganic: DIN, DIP; dissolved organic: DOC, DON, DOP; and particulate: POC, PN, PP) predictive model system of river nutrient export from watersheds (Global Nutrient Export from Watersheds (NEWS)) is presented. NEWS models estimate export from 5761 watersheds globally as a function of land use, nutrient inputs, hydrology, and other factors; regional and global scale patterns as of 1995 are presented here. Watershed sources and their relative magnitudes differ by element and form. For example, anthropogenic sources dominate the export of DIN and DIP at the global scale, although their anthropogenic sources differ significantly (diffuse and point, respectively). Natural sources dominate DON and DOP export globally, although diffuse anthropogenic sources dominate in several regions in Asia, Europe and N. America. “Hot spots” where yield (kg km−2 yr−1) is high for several elements and forms were identified, including parts of Indonesia, Japan, southern Asia, and Central America, due to anthropogenic N and P inputs in some regions and high water runoff in others. NEWS models provide a tool to examine past, current and future river export of nutrients, and how humans might impact element ratios and forms, and thereby affect estuaries and coastal seas.

TL;DR: In this article, the authors quantified maternal mortality throughout the world by underlying cause and age from 1990 to 2015 for ages 10-54 years by systematically compiling and processing all available data sources from 186 of 195 countries and territories.
