Description
The ecological benefits provided by trees include improving air quality (Nowak, et. al., 2006), mitigating climate change by sequestering carbon (Nowak, 1993), providing animal habitats (Livingston, et. al., 2003), and reducing heat (Edmonson, 2016), among others. Trees also provide numerous social benefits, impacting urban sustainability in particular by improving human health (Salmond, 2016), aesthetically and economically improving neighborhoods (Torres, 2012), and contributing to thriving communities by creating gathering spaces and even reducing crime (Abraham, et. al., 2010). Because of the tremendous potential of trees to provide social and ecological services, particularly in urban areas, tree planting has become an important facet of many sustainability initiatives. This thesis assesses one such initiative aimed at planting trees for the diverse benefits they provide. Valley Permaculture Alliance (VPA), a nonprofit based in Phoenix, Arizona, is known for its Shade Tree Program. The author conducted an internal, quantitative assessment of the program between August and December of 2015. The assessment included evaluation of several indicators of ecological and community health related to the presence of shade trees, culminating in a report released in 2016. This paper evaluates the use of sustainability indicators in the VPA assessment as well as their value in different types of organizations. It culminates with an assessment of VPA's strengths, challenges faced by the organization, and suggestions for its future development.

Description
Due to recent changes in climate, hurricanes have become more violent and destructive in the tropical region of the Caribbean. Extreme weather events have destroyed freshwater sources in many islands, affecting the overall food and water security of the region. More resilient forms of collecting freshwater for citizens and agriculture must be proposed in order to mitigate future weather impacts and increase future water security. Rainwater harvesting is an ideal and sustainable source of freshwater that can be adapted into existing households to help ease reliance on city water sources. Rainwater harvesting systems are effective sources of supplemental freshwater because they are easy to incorporate and inexpensive compared to other sources of freshwater. Dennis McClung, founder and owner of global charity, Garden Pool, has created the Climate Smart Farm, an agriculture system that incorporates rainwater harvesting to help create a more climate resilient farm. The Climate Smart Farm is adaptable and can be customized to incorporate solar energy, vertical gardening, aquaponics, hydroponics, plant propagation techniques, and more to grow crops in a more sustainable fashion. The system has recently been installed in the island of Barbuda, which was badly affected by the hurricanes in the summer of 2017. The system has been positively accepted by the country due to its ability to make agriculture simple and sustainable. It can be built with local materials, making the building process economy friendly. And with the addition of plant propagation techniques, the Climate Smart Farm can extend growing seasons and increase overall yields.

Description
This paper about the Garden Grub concerns the growing Agritech industry along with exposing middle school students to STEM education. Currently over half of America's students are not prepared to be successful in our technology driven world. These students did not have the opportunity to be exposed to many Science, Technology, Engineering, and Math related careers or majors before entering the working world and/or college. These students are unaware of the real-life applications these topics can have and will never have the chance to pursue these fields. Using the Garden Grub, students will be introduced to the world of Agritech and how traditional agriculture is changing in include more technology. The Garden Grub is designed to not only introduce students to STEM in general, but specifically the Agritech Industry. With the Garden Grub kit and instructions students will be able to construct a small device that will monitor the external temperature and the soil moisture of a plant they are growing. For future implementations of the Garden Grub, we will develop a structured lesson plan to teach the users more about the device they are building. This is so in the future users could continue their education in Agritech and STEM because they have more knowledge on the subjects From standalone testing the Garden Grub, the device was able to successfully monitor the lettuce to ensure that it grew successfully. The Garden Grub instructions and kit were tested in a fourth-grade classroom, where college volunteers worked with the students to begin to create their own device. While there was not enough time to successfully complete the product the fourth graders were more interested in STEM than when we first started. Even though they struggled in the beginning, students quickly learned basic concepts , such as +/- circuit power, transfer of data, and sensor connections. More recently we were able to go into a middle school and teach in a classroom with the students who were part of a coding elective course. Since our last outing we were able to update the user manual and prepare more ahead of time. This gave us more time to explain the concepts to the students, along with being able to successful build all of the devices. They began to think of ways that this device could be applicable to their lives along with how the Garden Grub could be improved in the future.

Description
The Prosopis genus of trees, also known as mesquites, are uniquely equipped to allow for an agroforestry regime in which crops can be grown beneath the canopy of the tree. Mesquites have the ability to redistribute water moisture in such a way that allows plants under the canopy to use water that has been brought up by the roots of mesquite trees. This means that there is a potential for food crops to be grown under the trees without using additional irrigation measures. This could be used where access to water is limited or for a sustainability-minded farmer who is trying to reduce water inputs in an arid environment. Mesquite trees produce a variety of products, including lumber and bean pods that can be ground down into an edible flour. Both products demand a high price in the marketplace and are produced in addition to the crops that can potentially be grown beneath the mesquite tree. In order to determine whether or not it is possible to grow crops under mesquite trees, I reviewed a wide range of literature regarding hydraulic redistribution, mesquite trees in general, and what plants might be best suited for growing beneath a mesquite. The list of plants was narrowed down to four crops that seemed most likely to survive in shaded, low water conditions in a hot environment. There has not been any research done on crops growing beneath mesquite trees, so the next step for research would be to experiment with each of the crops to determine how well each species can adapt to the specified conditions.

Description
Climate change presents the urgent need for effective sustainable water management that is capable of preserving natural resources while maintaining economical stability. States like California rely heavily on groundwater pumping for agricultural use, contributing to land subsidence and insufficient returns to water resources. The recent California drought has impacted agricultural production of certain crops. In this thesis, we present an agent-based model of farmers adapting to drought conditions by making crop choice decisions, much like the decisions Californian farmers have made. We use the Netlogo platform to capture the 2D spatial view of an agricultural system with changes in annual rainfall due to drought conditions. The goal of this model is to understand some of the simple rules farmers may follow to self-govern their consumption of a water resource. Farmer agents make their crop decisions based on deficit irrigation crop production function and a net present value discount rate. The farmers choose between a thirsty crop with a high production cost and a dry crop with a low production cost. Simulations results show that farmers switch crops in accordance with limited water and land resources. Farmers can maintain profit and yield by following simple rules of crop switching based on future yields and optimal irrigation. In drought conditions, individual agents expecting lower annual rainfall were able to increase their total profits. The maintenance of crop yield and profit is evidence of successful adaptation when farmers switch to crops that require less water.
