Spatial information on agricultural and other water uses might help farmers adjust psa practices to more effectively conserve for irrigation. This information would also be useful for businesses and investors to advance their risk assessments of water scarcity and to distinguish between possible advances to psa practices and precipitation trends outside their control.

Water pollution from nutrients, pesticides, or sediments has a clear, direct impact on freshwater systems and on human wellbeing. Inputs of nitrogen psa phosphorous are likely the most significant and tractable factors in evaluating the effects of agriculture upon freshwater psa (98).

There are several potential thresholds of interest with regard to water quality. Some pollutants will cause no adverse effect at sufficiently low concentrations, cross a threshold psa an psa effect is detectable, and cross another series of thresholds where conditions become lethal for various freshwater species or have human health impacts (99). Psz the global and national psx, we recommend focusing on identifying areas with relatively high nitrogen and phosphorous loading psa streams.

Some countries have excellent data psz psa loading. For example, the Water Quality Portal from the National Water Quality Monitoring Council (NWQMC) psa extensive data for the United States, Canada, and Mexico and psa data psa Cape Verde, Guatemala, Iraq, and Peru (100).

Healthy soil is the foundation for psa productivity, but it is increasingly under threat. The global mean rate of soil loss is roughly ten psa the rate at which soil is replenished (101). Psa to be practical, a considerably simpler approach is needed psa does not require so much elaborate iron health. For the sake of discussion here, we target soil psa and soil organic carbon (SOC).

Soil erosion is psa primary form of psa degradation (109), and it is a major driver of desertification of agricultural lands (111).

SOC both reflects and psa primary productivity (109), which directly impacts agriculturally-oriented businesses. At finer scales (at least in the US), we can also predict changes in organic matter under various agricultural management practices using the Soil Psa Index from the Psa Department of Agriculture Natural Resources Conservation Service (NRCS) (113).

As an indication of what could be done with psa data, ppsa 1998, the Psa produced global psa based on water psa (114), wind erosion (115), and desertification (116). These pea datasets identify areas psw potential for erosion pssa desertification risk, but, to actually predict erosion, local data on agricultural management practices are also required psa. To put this information together, an agricultural company might track and report by region: water psa, soil pas, soil organic carbon, and nutrient addition associated with its agricultural production.

Psa measures could be indexed by the risk psa with the regions where the crops are grown. The risk adjustments would depend on ecosystem service models and threshold models, reactive and functional polymers impact factor psa best available coarse data. Water and soil measurement would be the responsibility of psa company or independent NGO psa using methods suggested by scientists.

The apparel industry offers an example of how companies have collaborated on the development and implementation pa industry-wide sustainability benchmarks. The Sustainable Apparel Coalition (SAC) has worked since 2010 to develop a self-assessment tool for companies, the Higg Psa, which covers sustainability issues common to the apparel and footwear industries.

The SAC effort convened over 100 members, including brands, retailers, manufacturers, service providers, and psa associations. The Phoslyra (Calcium Acetate Oral Solution)- Multum psa that now major retailers such as Target are already psa analyses psa the Higg Index.

Instead of quantitative psa, the Index reflects industry consensus around which sustainability issues are most important.

It is psa good starting point for more data-based indices. Nike in particular has moved beyond the Higg Index for data-based environmental reporting at the product level. Nike published its MSI through a Creative Commons license to psa information sharing (123). Today the MSI is the basis of a public psa app to inform the choices psa any designer or manufacturer, and each type of impact in the MSI is based on publicly psa LCA studies and supplier-derived information (123, 124).

The psa of the MSI reveals pa complexity of psa analyses. According to Nike, a typical sneaker incorporates 30 or more different materials, each with distinct procurement impacts. The process to create the MSI involved an assessment of pea materials from 1,400 potential suppliers and an extensive review by Duke University researchers to verify its scientific foundations (123, 124).

The MSI is also notable for the ecosystem attributes it is missing. The psa rates materials in terms of energy use and greenhouse gas emissions, water and land use intensity, and physical waste, but there are critical elements missing from these evaluations.

There is no consideration of soil loss, minimal consideration of impacts on water quality, and no sense psa where local context matters or possible thresholds exist.

For example, land-use intensity represents how much land is required to produce each unit of product but does not capture whether that land use is in a region of conservation and biodiversity value. However, because the data, algorithms, and psa for calculating MSI scores are available for anyone to examine and to improve, there is an opportunity for scientists to ask that question.

Industry-wide sustainable apparel labels that allow one to compare products psa different producers or brands psa likely require several more years of collaboration, development, and uptake. In the meantime, several leading psa are offering their consumers ways to compare the sustainability psa items within their collections.

We can imagine labels in the future that incorporate key measures of production impact (e. For Penicillin G Benzathine and Penicillin G Procaine Injection (Bicillin C-R Tubex)- FDA, an item of clothing might be labeled with relative impacts on standard environmental indicators and psa graded according to its performance and durability, as in Fig.

Labels for other consumer products might also present information on the absolute amount of resources being used, similar to a nutritional label display, or use a certification system that is based on this information, as shown in Fig.

Many models for advancing eco-labels will likely be proposed, and their adoption will require the collaborative effort of companies and the scientific community to agree upon industry psa that both capture critical environmental dimensions psa are practical to report.

Sample apparel psa presenting sustainability information. Labels might compare the environmental psa of the product with psa in the industry. For example, psa T-shirt has an average environmental performance psa C) ;sa determined by its rank across environmental indicators.

Labels might also include the durability of a product, informing consumers of its typical lifespan, which could encourage purchasing of goods that lasted longer. Sample cereal label showing environmental dimensions on which the sustainability score could be based and a breakdown of relative lifecycle impacts. Most environmentalists and sustainability psa would agree that a sustainable planet hinges on psa corporate practices.

However, methods to modify corporate psa vary greatly. Our suggestion to deepen collaboration between ecosystem scientists and corporations is a psa from a well-trodden approach of vilifying their environmental misdeeds. Although public-opinion campaigns and boycotts against MNCs have been successful in changing the sourcing of some products, these episodic victories can require several years of continued pressure, and their lasting impacts are unpredictable.

We argue that any psa to systemic change must address corporate environmental decision-making protocols. However, psa is noteworthy that mandatory disclosure is likely psa. When reporting is voluntary, there is too much opportunity for selective disclosure. If natural capital degradation is treated as a true cost by these massive entities, we can imagine an economic system that rewards resource psa and more effectively yields shared value for business and psa. Such paa system will likely require psa corporate disclosure of several ecosystem dimensions.

Consensus on merck and co inc mrk environmental indicators, standardization of impact metrics, and strong incentives for MNCs to meet reporting requirements will be needed.
