Thinking in Systems by Donella Meadows "Dana Meadows' exposition in this book exhibits a degree of clarity and simplicity that can only be attained by one who profoundly and honestly understands the subject at hand--in this case systems modeling. Many thanks to Diana Wright for bringing this extra legacy from Dana to us."—Herman Daly, Professor, School of Public Policy, University of Maryland at College Park In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet— Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Meadows’ newly released manuscript, Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global.

Five Global Seed Banks That Are Protecting Biodiversity 2inShare Share By Victoria Russo Almost all food begins with a seed. Even when people eat meat or other animal products, those animals were most likely fed on grasses or grains that began as seeds. Seeds are the basis of plant life and growth, and without them, the world would go hungry. Systems Thinking Resources - The Donella Meadows Institute Concepts and Frameworks The Five Learning Disciplines Developed by renowned systems thinker Peter Senge, these five disciplines each enhance the ability of a person or organization to use learning effectively. Leveraged together, they contribute heavily to the success of learning organizations, defined by Senge as, “…organizations where people continually expand their capacity to create the results they truly desire, where new and expansive patterns of thinking are nurtured, where collective aspiration is set free, and where people are continually learning to see the whole together.” The five learning disciplines are Personal MasteryMental ModelsShared VisionTeam LearningSystems Thinking

Implications of climate change for agricultural productivity in the early twenty-first century (a) Changes in mean climate The nature of agriculture and farming practices in any particular location are strongly influenced by the long-term mean climate state—the experience and infrastructure of local farming communities are generally appropriate to particular types of farming and to a particular group of crops which are known to be productive under the current climate. Changes in the mean climate away from current states may require adjustments to current practices in order to maintain productivity, and in some cases the optimum type of farming may change. Higher growing season temperatures can significantly impact agricultural productivity, farm incomes and food security (Battisti & Naylor 2009). In mid and high latitudes, the suitability and productivity of crops are projected to increase and extend northwards, especially for cereals and cool season seed crops (Maracchi et al. 2005; Tuck et al. 2006; Olesen et al. 2007).

Human-based computation Human-based computation (HBC) is a computer science technique in which a machine performs its function by outsourcing certain steps to humans. This approach uses differences in abilities and alternative costs between humans and computer agents to achieve symbiotic human-computer interaction. In traditional computation, a human employs a computer[1] to solve a problem; a human provides a formalized problem description and an algorithm to a computer, and receives a solution to interpret.

5 Reasons Why Butter is a Superfood I ate a quarter pound of butter today. Yep, that is one whole stick. If you want to know how that is possible, let me explain: 2 tbs. mixed into half a batch of Paleo Cornbread Muffins2 tbs. slathered on top of said muffins2 tbs. stirred into warm butternut squash pureé2 tbs. tossed with steamed carrots, salt, and chopped fresh thyme You may be holding back a gag reflex after reading that.

The Global Brain Institute The GBI uses scientific methods to better understand the global evolution towards ever-stronger connectivity between people, software and machines. By developing concrete models of this development, we can anticipate both its promises and its perils. That would help us to steer a course towards the best possible outcome for humanity. Objectives

Why Butter Is Better Read this article in: French | Portuguese | Spanish When the fabricated food folks and apologists for the corporate farm realized that they couldn't block America's growing interest in diet and nutrition, a movement that would ultimately put an end to America's biggest and most monopolistic industries, they infiltrated the movement and put a few sinister twists on information going out to the public. Item number one in the disinformation campaign was the assertion that naturally saturated fats from animal sources are the root cause of the current heart disease and cancer plague. Butter bore the brunt of the attack, and was accused of terrible crimes. The Diet Dictocrats told us that it was better to switch to polyunsaturated margarine and most Americans did.
