Nutrients and water: closing yield gaps

Published

on

Paul West of the University of Minnesota’s Institute on the Environment writes about a recent study conducted by some of his colleagues about changes in nutrient and water management to reduce the yield gap.

Several reports estimate that we need to double current crop production by 2050 in order to meet the needs of a growing population that eats more meat and uses more crops for fuel. Some strategies–like reducing waste and reducing meat consumption–would reduce pressure on our land and water resources and free up more food calories that are potentially available.

But we commonly assume that increasing crop production will come at a cost of increased environmental damages to our climate, water, and natural habitat.  It turns out that does not have to be the case.

In their recent article in Nature, Nathan Mueller and colleagues estimate that yields could be increased for most major crops by 45-70%, with the biggest opportunities in Eastern Europe, sub-Saharan Africa, East Asia, and South Asia (see Figure 1).

The vast majority of yield variability within a particular climate is from differences in nutrient and water management. This is great news, as it means that these yield gains are possible with today’s seeds and management practices.

Many foundations and companies emphasise the need for seeds that utilise water and nutrients more efficiently. That’s a great mid- and long-term strategy, but yields can be increased a lot in the meantime through changes in management.

Nutrient and water management will always be a key part of the solution in many areas where hunger is currently widespread, soils are depleted of nutrients, and the climate is arid.

However, places like China, India United States, and Western Europe could reduce fertilizer use while still maintaining high yields. (Click to enlarge).

Yes, in most regions it will require additional nutrients or water to boost yields. Crops are notoriously inefficient in their use of both organic and mineral fertilisers–they typically only utilise half of what’s applied–so additional management practices may be needed to ensure water quality is maintained.

However, fertiliser application could be greatly reduced in many areas while still maintaining high yields (see Figure 2).

Mueller and colleagues estimate that current yields for maize, wheat, and rice could be maintained while reducing global input of nitrogen and phosphorus by 28 and 38 percent, respectively. The biggest opportunities for these reductions are in China, United States, Western Europe, and India.

Analyses like this study help define what’s biologically and physically possible. Ideally, lessons learned here can be used to help guide investments in markets and infrastructure through a combination or public and private capital, policy, and education.

What Kitchen Suits Your Style? Modern, Classic or Shaker?

A kitchen is the centre of the home. Your kitchen ranges between where friends and family gather, talk about their day, cook meals, have drinks, to somewhere you can just enjoy each other’s company. The kitchen is the heart of the home. But, everyone’s lifestyle is different. Everyone’s taste is different. So, you need a kitchen that not only mirrors your lifestyle but matches your taste too. Whilst some prefer a more traditional design, others want a modern feel or flair – and it’s all down to personal taste.

When it comes to redesigning your kitchen, what style would you go for? It’s a difficult one isn’t it. With so many different styles to go for, how can you know exactly what you want until you’ve seen it in action?

This design guide will get you one step closer to picking your dream kitchen for your home.

Ways Green Preppers Are Trying to Protect their Privacy

Published

on

Environmental activists are not given the admiration that they deserve. A recent poll by Gallup found that a whopping 32% of Americans still doubt the existence of global warming. The government’s attitude is even worse.

Many global warming activists and green preppers have raised the alarm bell on climate change over the past few years. Government officials have taken notice and begun tracking their activity online. Even former National Guard officers have admitted that green preppers and climate activists are being targeted for terrorist watchlists.

Of course, the extent of their surveillance depends on the context of activism. People that make benign claims about climate change are unlikely to end up on a watchlist, although it is possible if they make allusions to their disdain of the government. However, even the most pacifistic and well intentioned environmental activists may unwittingly trigger some algorithm and be on the wrong side of a criminal investigation.

How could something like this happen? Here are some possibilities:

  • They could share a post on social media from a climate extremist group or another individual on the climate watchlist.
  • They could overly politicize their social media content, such as being highly critical of the president.
  • They could use figures of speech that may be misinterpreted as threats.
  • They might praise the goals of a climate change extremist organization that as previously resorted to violence, even if they don’t condone the actual means.

Preppers and environmental activists must do everything in their power to protect their privacy. Failing to do so could cost them their reputation, future career opportunities or even their freedom. Here are some ways that they are contacting themselves.

Living Off the Grid and Only Venturing to Civilization for Online Use

The more digital footprints you leave behind, the greater attention you draw. People that hold controversial views on environmentalism or doomsday prepping must minimize their digital paper trail.

Living off the grid is probably the best way to protect your privacy. You can make occasional trips to town to use the Wi-Fi and stock up on supplies.

Know the Surveillance Policies of Public Wi-Fi Providers

Using Wi-Fi away from your home can be a good way to protect your privacy.However, choosing the right public Wi-Fi providers is going to be very important.

Keep in mind that some corporate coffee shops such a Starbucks can store tapes for up to 60 days. Mom and pop businesses don’t have the technology nor the interest to store them that long. They generally store tips for only 24 hours and delete them afterwards. This gives you a good window of opportunity to post your thoughts on climate change without being detected.

Always use a VPN with a No Logging Policy

Using a VPN is one of the best ways to protect your online privacy. However, some of these providers do a much better job than others. What is a VPN and what should you look for when choosing one? Here are some things to look for when making a selection:

  • Make sure they are based in a country that has strict laws on protecting user privacy. VPNs that are based out of Switzerland, Panama for the British Virgin Islands are always good bets.
  • Look for VPN that has a strict no logging policy. Some VPNs will actually track the websites that you visit, which almost entirely defeats the purpose. Most obviously much better than this, but many also track Your connections and logging data. You want to use a VPN that doesn’t keep any logs at all.
  • Try to choose a VPN that has an Internet kill switch. This means that all content will stop serving if your VPN connection drops, which prevents your personal data from leaking out of the VPN tunnel.

You will be much safer if you use a high-quality VPN consistently, especially if you have controversial views on climate related issues or doomsday prepping.
