Weather and Climate Extremes in a Changing Climate. Regions of Focus: North America, Hawaii, Caribbean, and U.S. Pacific Islands. The U.S. Climate Change Science Program and the Subcommittee on Global Change Research today released a scientific assessment ("Weather and Climate Extremes in a Changing Climate") that provides the first comprehensive analysis of observed and projected changes in weather and climate extremes in North America and U.S. territories. Among the findings reported in this assessment are that droughts, heavy downpours, excessive heat, and intense hurricanes are likely to become more commonplace as humans continue to increase the atmospheric concentrations of heat-trapping greenhouse gases. Global warming of the past 50 years is due primarily to human-induced increases in heat-trapping gases, according to the report. Many types of extreme weather and climate event changes have been observed during this time period and continued changes are projected for this century. Specific future projections include: Abnormally hot days and nights, along with heat waves, are very likely to become more common. Cold nights are very likely to become less common. Sea ice extent is expected to continue to decrease and may even disappear in the Arctic Ocean in summer in coming decades. Precipitation, on average, is likely to be less frequent but more intense. Droughts are likely to become more frequent and severe in some regions. Hurricanes will likely have increased precipitation and wind. The strongest cold-season storms in the Atlantic and Pacific are likely to produce stronger winds and higher extreme wave heights.

What is Edible Forest Gardening?
Edible forest gardening is the art and science of putting plants together in woodlandlike patterns that forge mutually beneficial relationships, creating a garden ecosystem that is more than the sum of its parts. You can grow fruits, nuts, vegetables, herbs, mushrooms, other useful plants, and animals in a way that mimics natural ecosystems. You can create a beautiful, diverse, high-yield garden. If designed with care and deep understanding of ecosystem function, you can also design a garden that is largely self-maintaining. In many of the world's temperate-climate regions, your garden would soon start reverting to forest if you were to stop managing it. We humans work hard to hold back succession—mowing, weeding, plowing, and spraying. If the successional process were the wind, we would be constantly motoring against it. Why not put up a sail and glide along with the land's natural tendency to grow trees? By mimicking the structure and function of forest ecosystems we can gain a number of benefits.

Why Grow an Edible Forest Garden?
While each forest gardener will have unique design goals, forest gardening in general has three primary practical intentions:

• High yields of diverse products such as food, fuel, fiber, fodder, fertilizer, 'farmaceuticals' and fun;
• A largely self-maintaining garden and;
• A healthy ecosystem.

These three goals are mutually reinforcing. For example, diverse crops make it easier to design a healthy, self-maintaining ecosystem, and a healthy garden ecosystem should have reduced maintenance requirements. However, forest gardening also has higher aims.

As Masanobu Fukuoka once said, "The ultimate goal of farming is not the growing of crops, but the cultivation and perfection of human beings."

Over the years, hundreds of thousands of miles of river corridors and millions of acres of wetlands have been damaged throughout the nation. Restoration seeks to return some of these ecosystems to their approximate pre-disturbance conditions.

The ecological and societal benefits of river corridor and wetlands restoration are substantial:

Rivers transport water, sediment, and nutrients from the land to the sea, play an important role in building deltas and beaches, and regulate the salinity and fertility of estuaries and coastal zones. Rivers serve as corridors for migratory birds and fish, and provide habitat to many unique species of plants and animals, including federally endangered and threatened aquatic species. According to the 1985 National Survey of Fishing, Hunting, and Wildlife -Associated Recreation (U.S. DOI, Fish and Wildlife Service, 1988), 38.4 million fishermen spent $17.8 billion for non-Great Lakes freshwater fishing in 1985, with 45 percent of reported anglers fishing in rivers and streams.

Wetlands provide food, protection from predators, and other vital habitat factors for many of the nation's fish and wildlife species, including endangered and threatened species. In addition, wetland ecotypes have economic value associated with recreational, commercial, and subsistence use of fish and wildlife resources and they remove pollutants from overland flows before they reach our lakes, rivers and bays.

Wetlands intercept storm runoff and release floodwaters gradually to downstream systems. When wetlands are converted to systems without water retention capacity, downstream flooding problems increase.

From 1982 to 1992, a total of 768,700 acres of wetlands were gained as a result of restoration activities around the nation (USDA, 1997). Likewise, numerous miles of rivers and streams were restored in our nations watersheds over the same time period. When properly planned, executed and managed, restoration works; its success can be attributed to the hard work and dedication of practitioners, scientists, and others who seek to heal damaged natural systems and improve our communities.

EPA Wetlands, oceans & Watersheds

Learn! Explore! Take Action!

Celebrate the vital importance of wetlands to the Nation's ecological, economic, and social health.

May, American Wetlands Month is also a great opportunity to discover and teach others about the important role that wetlands play in our environment and the significant benefits they provide - improved water quality, increased water storage and supply, reduced flood and storm surge risk, and critical habitat for plants, fish, and wildlife.

In organizing its activities this year, EPA is placing special emphasis on encouraging Americans to:

1. Learn about wetlands. This is a great time to better understand what a wetland is, where wetlands can be found, and the importance of wetlands. Activities may include reading and studying about wetland areas, drawing maps or illustrations of wetlands, and identifying native species found in wetlands. Information on wetlands and the important benefits they provide is available on this website, through EPA's wetland fact sheet series, or by visiting the websites of our partners.
2. Explore a wetland near you. Unless you live in the most extreme climate zones, there is a good chance a scenic wetland exists nearby for you to visit and explore during American Wetlands Month and throughout the year. To find a wetland near you, consult your local parks department, state natural resource agency, or the United States Fish and Wildlife Service (http://www.fws.gov/refuges). If you live in the Washington, DC area, a guide has been created to highlight wetlands and wildlife sanctuaries.
3. Take action to protect and restore wetlands. Support and promote wetlands informing community members about wetlands' vital roles, "adopting" a wetland, joining a local watershed group, or participating in a wetland monitoring, restoration, or cleanup project. There are many other actions Americans can take to help conserve wetlands.To learn more about what you can do to help protect and restore these valuable natural resources in your state or local area, visit http://www.epa.gov/owow/wetlands/awm/#you.

The Department of Water Resources (DWR) has released a new water resources data management tool called the Integrated Water Resources Information System (IWRIS).

Web-based Geographic Information System for Water Management

IWRIS is a Web-based Geographic Information System application that allows users to access, integrate, query, and visualize multiple sets of data from diverse sources.

Some of the databases currently accessible through IWRIS include DWR’s Water Data Library, California Data Exchange Center (CDEC), United States Geological Survey streamflow data, Local Groundwater Assistance Grants (AB303), and data from local agencies. The system will be expanded with additional data sets and functionality in the future.

Improve Water Data Management for Integrated Regional Water Management

DWR developed IWRIS to improve water data management and scientific understanding in support of Integrated Regional Water Management (IRWM).

The California Water Plan Update 2005 identifies IRWM as a key initiative to ensure reliable water supplies through the year 2030.

The Department of Water Resources operates and maintains the State Water Project, provides dam safety and flood control and inspection services, assists local water districts in water management and water conservation planning, and plans for future statewide water needs.

Map of below normal 7-day average streamflow compared to historical streamflow for the day of year (United States)

This map shows the 7-day average streamflow conditions in hydrologic units of the United States and Puerto Rico for the day of year. The colors represent 7-day average streamflow percentiles based on historical streamflow for the day of the year.

The Importance of  Landscaping and Streamflow

Streams feed and pull from the groundwater supply, the water table.  When streams in a region are low, landscaping  is also vulnerable to drought conditions.  Some regions are more susceptible to low streamflow conditions on a seasonal basis, but some areas have increasing population stresses put on a normally healthy ecosystem.  Landscaping professionals and conscientious landowners can play an important role in the health of their ecosystem and their longterm water supply by applying conservation practices in selection of plant species that require  minimal water, and using protective devices such as cisterns, swales and  raingardens to protect the groundwater system from contaminants and pollution.

The Land Institute's strategy includes collaboration with public institutions in order to direct more research in the direction of Natural Systems Agriculture.  

The team at the Land Institute feels comfortable having demonstrated the scientific feasibility of their proposal for a Natural Systems Agriculture. Because this work deals with basic biological questions and principles, the implications are applicable worldwide. If Natural Systems Agriculture were fully adopted, we could one day see the end of agricultural scientists from industrialized societies delivering agronomic methods and technologies from their fossil fuel-intensive infrastructures into developing countries and thereby saddling them with brittle economies.

Perennial Grain...a hybrid of intermediate wheatgrass and triticale could produce a more sustainable food crop that lives for years and builds deep root systems to tap deeper water sources. 

According to Scientific American's article about the Land Institute in 2007, Americans assume food production is easy and highly efficient already.  However, reality is that agriculture requires vast areas of land, regular high quantities of waer, energy and chemicals to meet the demands for our escalating human and animal populatons.

The UN sponsored Millennium Ecosystem Assessment suggested that agriculture may be the "largest threat to biodiversity and ecosystem function of any single human activity."  OUCH!

"Today, most of humanity's food comes directly or indirectly (as animals feed) from cereal grains, legumes and oilseed crops.  These staples are appealing to producers and consumers because they are easy to transport and store, relatively imperishable, and fairly high in protein and calories.  As a result, such crops occupy about 80% of global agricultural land.  BUT, they are all annual plants, meaning that they must be grown anew from seeds every eyar, typically using resource-intensive cultivation methods. More troubling, the environmental degradation caused by agriculture will likely worsen as the hungry human population grows to eight billion or 10 billion in the coming decades."

Plant Breeders, Agronomists and Ecologists Strive for Solutions

Grain-cropping systems that functin much like natural ecosystems that have been displaced by agriculture is the holy grain for agriculture researchers.

Significant advances in plant breeding science are bringing this goal within sight at last!

Kansas plant geneticist Wes Jackson looked at the ecosystems that preceded agriculture to look for a solution. Mixtures of perennial plants once dominated nearly all the planet's landscapes and they still do in uncultivated areas today. 

More than 85% of North America's native plant species are PERENNIALS.

Because annuals have relatively shallow roots -- most less than 0.3 meters -- farming areas have problems with erosion, foil fertility depletion and water contamination...and lack of nature's natural farmers, wildlife.

Today the traits of perennials are becoming better appreciated for their root depths of more than two meters, plant communities that regulate ecosystem functions such as water management and carbon and nitrogen cycling.  They are also highly productive yet resilient in the face of environmental stresses.

Timothy grass, a perennial hay crop, is roughly 54 times more effective in maintaining topsoil than annual crops.  Scientists also find a fivefold reduction in water loss and a 35-fold reduction in nitrate loss from soil planted with alfalfa and mixed perennial grasses compared with soil under corn and soybeans.

Carbon sequestration by perennials is also boosted.  Carbon is the main ingredient of soil organic matter and can contain 50% more than annually cropped fields.   And perennial fields do not need to be worked every year, so less farm machinery cycles and less fertilizers and pestcides also reduce fossil fuel use.

Wildlife also benefits -- bird populations can be seven times more dense in perennial crop fields than annual crop fields. 

And perennials are far more capable of sustainable cultivation on marginal lands, which already have poor soil quality or would be quickly depleted by a few years of intensive annual cropping.

Perennial plant breeding research are focusing on wheat, sorghum, sunflower, intermediate wheatgrass and other species as perennial grain crops.

At The Land Institute, breeders are working both on domesticating perennial wheatgrass and on crossing assorted perennial wheatgrass species with annual wheats.  Although perennial crops such as alfalfa and sugarcane already exist around the world, none has seed yields comparable to those of annual grain crops...and  here is where creative plant breeding  works with  the growing environment, selective  breeding stock, and  judicious use of fertilizers to increase the yield of these perennial grains.

Deep roots mean resilience, and that trait might be more important than many short term plant attributes currently valued by agriculture.

Additional programs include the Climate and Energy Project (CEP)   See www.climateandenergy.org . The Land Institute formed this new project on climate and energy in February 2007. Because of the close connections between climate change, energy from coal, and agricultural vulnerabilities -- research is growing to explore the issues and find solutions to the issues that connect energy and farming.
