Non Technical Summary
International research is a mechanism to enhance comprehension of distinct agroecosystems. We are requesting fellowships and IRTAs for 3 PhD students in agricultural science. They will develop part of their research/classes in foreign partner institutions (Turkey, UK, and Brazil). Recruitment strategies will be used to seek highly qualified students from minority pools. Targeted Farm bill priority areas include plant/animal health and production, renewable bioenergy, natural resources, and environment, and agriculture systems and technology. The overall goal is to graduate 3 PhDs, emphasizing water management in diverse agroecosystems. Measurable objectives are: the number of recruited students from minority pools, PhD degrees awarded, and their career placement. We will accomplish project goals for the identified TESA area by providing the students, during the project duration, with a broad training in agroecology. Linking agricultural production with the environment using ecological principles and addressing social and economic aspects embedded in a range of production systems will provide the graduate students with comprehensive problem-solving skills. This program meets the USDA Strategic Goal 2 and Objectives: 1) Lead efforts to mitigate and adapt to climate change, drought, and extreme weather in agriculture and forestry; and 2) Contribute to clean and abundant water by protecting and enhancing water resources on national forests and working lands. Integrative training with multi-discipline, multi-site, and distance education are the key component to make a national impact on the identified TESA area.

Project Methods
Recruitment and selection of FellowsNN Fellows will be recruited through a four-prong process:1. Directed advertisement and recruitment will be coordinated with the UF Office of Academic Support and Florida Opportunity Scholars Program. At the University of Florida, UF OAS and FOS provide tutoring and academic support services to students from under-represented groups. Therefore, by directly recruiting from the highly motivated and well-prepared pool of minority students who are already on UF campus will be one of our approaches.2. Recruitment activities will be conducted in January and March during African-American and Hispanic-Latino student recruitment conferences held annually on the UF campus.Florida International University (FIU), a partner institution in this proposal, will also partner in the recruitment process.3. Targeted recruitment through the GRE service. We plan to purchase data from Kaplan's GRE service to directly solicit graduate school-bound students.4. In addition to these targeted recruitment activities, posters describing the program will be presented at Regional and State meetings of professional societies (ASA, CSSA, SSSA). A UF website for the NNF Program, a Facebook and LinkedIn sites, and a Twitter account for the program will be developed by the Program Assistant.Student selection process and criteriaProspective fellows will be identified through our four-prong recruitment process. Students will apply for the NNF Scholarship concurrently with their application to their respective Graduate Programs in Agricultural Sciences. Beyond basic criteria, NN fellows will be expected to have a minimum 3.0 GPA, demonstrated interest in water management in agroecosystems (enrollment in relevant graduate courses with at least 3.0/4 GPA), and professionalism (ability to manage time and extracurricular commitments). Top candidates will be invited to submit 1-page essays.Academic advising, research training, professional counseling, mentoring, pipelining Targeted TESA area (Integrative Biosciences for Sustainable Food and Agricultural Systems) requires a multidisciplinary training in ecological principles, agroecosystems, and management of natural resources including soil, water, and living organisms (microorganisms, plant, animals). Core competencies that each Fellow will be expected to attain include disciplines related to agronomy, biology, soil and water sciences, ecology, and statistics.Core disciplines include Principles of Agroecosystems, Crop Ecology, Soils for Environmental Professionals, Statistical Methods in Research, Ecophysiology, Crop Nutrition, and Sustainable Water Management. Elective classes taken in the foreign partner Universities will broaden the program to specific career interests, meeting the needs of the Integrative Biosciences for Sustainable Food and Agricultural Systems TESA area.Experiential learning: hands-on research, extension, teaching and other activities In addition to the experiential learning that the Fellows will be exposed in class laboratories, hands-on research activity will be required for all NN Fellows of this proposal. They will develop their research component focused in an international agroecosystem associated with one of the foreign partner institutions located in Turkey, UK, and Brazil. The research focus will be water management in agroecosystems, applying conservation practices and assessing mechanisms of drought tolerance in various species and ecosystems. The placement of NN Fellows in foreign partner institutions will provide innovative international leadership, management, and communication experiences for these students in the Integrative Biosciences for Sustainable Food and Agricultural Systems TESA area.Measuring performance outcomes Procedures to measure outcomes will include the following indices: a) number of contacted prospective underrepresented students; b) number of recruited underrepresented students; c) number of underrepresented students graduated; d) number of NNF placed in the agricultural sector; e) Tracking of NNF graduates over a five-year period. The goal is to contact all NNF graduates annually over a five-year period. During this time, technical competence and scholarly contribution of the graduates will be assessed. Compiled information will include number of peer reviewed publications and their respective impact on the scientific community, number of citations of their scientific articles, time spam between graduation and job placement, and link between the new job tasks and program developed during graduate school and TESA area. Outcomes of the evaluation will be used to improve future Fellows programs and they will be incorporated into NNF reportsDissemination of results and/or impacts Results obtained in the project will be described in the NNF reports and made available for all involved partner institutions. Reports will be sent to UF Office of Academic Support and Florida Opportunity Scholars Program and to other entities at UF including academic and recruiting offices and University higher Administration. Further dissemination will occur by providing the report to USDA agencies, Department of Education, and prospective students. In order to disseminate the results to a wide audience, a video will record the Fellow's steps along the program, including the on-campus period, experiential learning in the foreign partner institution, graduation, and career placement. The video will be available for the NNF program to use and disseminate the results for a broader audience.

Target Audience:In 2019-2020 period, we had two PhD students working on their respective projects. David Jaramillo was under the supervision of Dr. Jose Dubeux (PI) at UF IFAS NFREC/Agronomy and Victor Guerra under the supervision of Dr. Cheryl Mackowiak at UF IFAS NFREC/Soil and Water Sciences. The other student (Jamil Ghazal) dropped from the PhD program for personal reasons. David Jaramillo stayed six months abroad at University College Dublin (UCD) in Dublin, Irelandin the second semester of 2019. Heactively participated in Dr. Helen Sheridan's program during that time period. David Jaramillo succesfully graduated from his PhD in June 2020 and he is starting a PhD with USDA-ARS at Penn State. Victor Guerra went to University of Gottingen, Germany where he stayed for four months and succesfully completed his activities there. Victor is still working on his PhD and should be able to graduate in theFall 2020/Spring 2021. Dr. Mackowiak has secured other funds to pay for the extended period beyond this NNF project. In addition, research results were targeted at the scientific community in areas of forage physiology, soil nutrient management/water quality, and soil microbial ecology. The applied aspects of research under this program targeted county extension faculty (tri-state region), Florida Department of Agriculture, Northwest Florida Water Management, USDA-NRCS, Florida Cattlemen Assoc., Perennial Peanut Producers Assoc., regional ranchers, farmers, and K thru 12 children interested in plant and soil sciences. Changes/Problems:Because of discontinuation of students due to personal problems, during different stages of the program, we will be able to graduate only two PhDs (instead of three). The two PhDs that we are graduating, however, had a full experience with the international study abroad and will increase the pool of PhD for underrepresented minorities in this field. What opportunities for training and professional development has the project provided?Preparing educational materials for extension and teaching activities, along with participating in conferences and meetings both, in the United States and Internationally have provided opportunities for professional development. As a teaching assistant for a combined graduate/undergraduate Environmental Pedology course, Victor Guerra planned field labs and procured necessary resources. David Jaramillo actively participated in field days and other extension activities. Multiple field day extension events provided the opportunity to practice delivering effective oral presentations, conveying accurate scientific information in a meaningful manner to producers and non-scientists. Victor Guerra attended the 25th anniversary of the United Nations Convention to Combat Desertification at the International Soil Congress 2019 in Ankara, Turkey, numerous professional connections were made with governmental and university associated researchers from Turkey and other United Nations member countries who are continued contacts presenting potential collaborating partners and career opportunities. This meeting also provided unique insight into the ongoing work in Turkey and the surrounding region related to grassland management under limited water resources. Attending master classes during the Wageningen Soil Conference 2019 in Wageningen, Netherlands provided training in methods for assessing mycorrhizal colonization of roots and developing soil related impact assessment plans in multicultural, multidisciplinary team settings. A major professional development opportunity also took place while presenting a poster and oral presentation during the 2019 Soil Science Society of America meeting. Experience with specialized equipment for determining hydraulic properties of soils provided a training opportunity that translated to a more rewarding experience during a stay at University of Goettingen, Germany. The same equipment was utilized to assess soils in agroforestry systems at multiple sites in Germany and contributed to a large, multi-institutional research project known as Sustainable Intensification of Agriculture through Agroforestry. This experience was professionally enriching and resulted in developing skills for operating in a multicultural research setting, along with developing lasting professional contacts for post-doctorate opportunities. Training in molecular methods and bioinformatics during this period were instrumental in the development of a publication and continued collaborations between host and home laboratories. Further student training opportunity presented itself by assisting first year Ph.D. and MSc students in the use of laboratory equipment, methods and data analysis upon their arrival. David Jaramillo also had the opportunity to attend a course on stable isotopes in the UK, besides his international experience at UCD in Ireland. How have the results been disseminated to communities of interest?The results have been presented at producer field-day events and extension publications, benefitting producers and extension agents. The results have also been published in a peer-reviewed scientific journal and made available via open-access. Results have also been disseminated in-person to international researchers through presentations given during the international collaboration visits. What do you plan to do during the next reporting period to accomplish the goals?If no-cost extension is allowed, Victor Guerra will conclude his PhD in the Fall/2020 or Spring/2021 at the latest. He is finishing laboratory and data analyzes, and will write the PhD dissertation. He is also actively seeking post-doc opportunities.

Impacts
What was accomplished under these goals? - David Jaramillo succesfully defended his PhD Dissertation. David is from a minority pool (Latin) and he is starting a Post-Doc position at ARS-USDA at Penn State University. In 2019, David spent six months abroad at University College Dublin, Ireland, which was also part of the goals of the project. - Victor Guerra is finalizing his PhD in the Fall 2020 or Spring 2021. Victor spent four months at the University of Goettingen, Germany, as part of the current objectives. Victor is already seeking Post-Doc positions and plans to stay in academia. Victor is from a minority pool of students (Latin). Because of several personal issues and students dropping, we will be able to graduate only two PhDs with the resources funded by the project.

Target Audience:Our main target audience is the training of underrepresented groups in Agroecology. We also want to stregthen their graduate education by developing international study abroadprograms. The three PhD students are moving forward with their projects. Two (David Jaramillo and Victor Guerra)out of three already sucessfuly completed their qualifying examand now are PhD candidates. David Jaramillo willspend six months at the University College Dublin in Ireland and Victor Guerra is spending four months in Germany at the University of Goettingen. Jamil Ghazal isat an earliest stage in the program and plan to develop his study abroad in Spring 2020. In addition to the trainning of these students, their research project will generate important informationassessing management of water scarcityin different agroecosystems. Changes/Problems:We faced difficulty at the beggining of the project with recruitment of students from underrepresented groups.We also had to replace a couple of students because of personal issues they were facing.This resulted in the delay of the program for one of the students,Jamil Ghazal, who started at a later date. We are already procuring funds to complete his program in case he is not able to finisg by the end of this project. What opportunities for training and professional development has the project provided?Besides the three PhD students, the project alsoprovide opportunities to train undergraduate students.During the duration of the project, we already trained six undegraduate students in the subject area of the project. How have the results been disseminated to communities of interest?Results have been disseminated via field days,extrension reports, and web-based extension material. The extension programs below highlighted results of the project: 7-8 August 2018: Forage Workers Tour 14 September 2018: Grazing School 14 March 2019: IST Grazing Management of Cover Crops 15 March 2019: Beef and Forage Field Day 30 May 2019: Perennial Peanut Field Day What do you plan to do during the next reporting period to accomplish the goals?Graduate students are on track for graduation. We plan to finalize their research analyses and start the writing of their dissertation.

Impacts
What was accomplished under these goals? The project is on track to meet the goal to graduate three PhD students emphasizing water management in diverse agroecosystems. Two students already qualified and are spending the second semester of 2019 in study abroadprograms.

Progress 07/15/17 to 07/14/18

Outputs
Target Audience:In 2017-2018 period, we had three PhD students working on their respective projects. David Jaramillo, under the supervision of Dr. Jose Dubeux at UF-IFAS NFREC/Agronomy, Vitor Guerra, under the supervision of Dr. Cheryl Mackowiak at UF-IFAS NFREC/ Soil and Water Sciences, and Erin Doughtie, under the supervision of Dr. Diane Rowland, UF IFAS Agronomy. Erin Doughtie dropped the program in December 2017 for personal/family reasons (moved to California). Dr. Rowland was able to recruit another student (Jamil Ghazal) who will initiate his program in July 2018. Dr. Rowland was able to secure funds to continue Jamil's program after termination of the current NNF funding. All three PhD students are in compliance with NNF program requirements. Their PhD projects are also related to our project (Managing Water Scarcity in Diverse Agroecosystems. In addition to the graduate students (our major target group), we were also able to reach out producers and extension agents through production of education materials and field days. Changes/Problems:Erin Doughtie dropped the program for personal/family reasons. We had to recruit a new student and that delayed the project. We were able to recruit a new student and to secure funds for the continuation of the program after termination of NNF project by 2020. What opportunities for training and professional development has the project provided?Every year the students attend the major scientific meeting in their respective area and give oral presentations as well as present posters. In 2017, David Jaramillo, one of our students, place 2nd in a National Oral Competition in the C-06 division of Crop Science Society. This is a prestigious award, considering the competition with nation-wide graduate students. We also received a grant from the University of Florida to enhance the International exposure of our program. We were able to bring three PhD students to Ireland last summer (2017). We strengthened our collaboration with Dr. Helen Sherida from University College Dublin. This will be a potential place where David Jaramillo is planning to develop his internship abroad. How have the results been disseminated to communities of interest?As illustrated in our publication record, we developed a series of extension and education materials. These were published in Industry Journals, professional websites, and peer-reviewed journals. We also developed several field days to deliver information to land managers. What do you plan to do during the next reporting period to accomplish the goals?We will continue the research activities for all graduate student involved. They are also planning to develop the International internship in 2019. Students will also move on to the qualifying exams in order to proceed in their pursuit for the PhD degree.

Impacts
What was accomplished under these goals? Two out of three PhD students are in the middle of their programs. David Jaramillo already collected data in 2017 and will continue to collect data until Fall 2019. He is planning to develop his International Internship in 2019. Vitor Guerra is in a similar position. Because Erin Doughtie dropped the program, the new recruited PhD student will start in July 2018. Jamil Ghazal will develop the project "Examination of ecophysiological responses to water deficit in Costa Rica coffee agroecosystems". Therefore, we have met the recruitment goals. The other goals will occur whenever these students finish their degrees.

Outputs
Target Audience:We recruited all three PhD students and they are all within our target audience. The students are Erin Doughtie and she is under the supervision of Dr. Diane Rowland from the Agronomy Department. The second student is Victor Guerra who is under the supervision of Dr. Cheryl Mackowiak from the Soil and Water Sciences Department. Victor finished his degree in Agronomy and is going for the PhD now. The third student is David Jaramillo. David finished his MS degree under another NNF project and moved to our project to do his PhD. David Jaramillo is under the supervision of Jose Dubeux. All three students are in compliance with the NNF requirements. Their projects will address different topics, but all of them related to the broader subject of the project, which is "Managing water scarcity in diverse agroecosystems". Changes/Problems:No major changes to report. What opportunities for training and professional development has the project provided?In addition to the three PhD students that we are trainning, we also created opportunities for several internships in our projects. These other students are also being exposed to the agroecological concepts of the distinct projects.Four undergraduatestudent internsare currently beingtrainned in projects related to the NNF program, and four more interns are coming in the second semester of 2017. How have the results been disseminated to communities of interest?The three projects just started. Erin Doughtie and Victor Guerra started in January 2017 and David Jaramillo started in May 2017. All these projects will be disseminated towards our target audience, which are row crop and livestock producers from North and Central Florida. Tow of the supervisors have extension appointments and regular field days occur at the Experimental Stations and on-farm. What do you plan to do during the next reporting period to accomplish the goals?Students will initiate their research projects. They are also prospecting foreign Institutions to develop the study abroad program. Jose Dubeux received a travel grant from the University of Florida - IFAS Research Office and will take David Jaramillo and tow other PhD students from his program to visit University College Dublin (UCD) in July 2017. The group from UCD is working on multi-functional grasslands and perhaps they will be a destination for David Jaramillo study abroad portion within the NNF. Erin Doughtie will develop part of her research in UK, at Harper Adams University. Victor Guerra has previous experience in Turkey and is planning to develop his study abroad there. Therefore, the goals are on target and things are progressing as expected.

Impacts
What was accomplished under these goals? We are progressing towards the project goal. We recruited all three PhD students and they come from minority groups. Two of them have latin background and one of them is a woman, which is considered minority in agricultural careers. All of them are US citizens, as required by the grant. These three students will be graduating by the end of the project. They are also having a broad training in Agroecology and are following the curriculum of the new PhD concentration in Agroecology. All three of them will spend at least 4 months abroad, as part of their trainning.

    Outputs
    Target Audience:We dedicated our time during the first year of the project on recruiting efforts and also approving the PhD concentration in Agroecology at the University of Florida. Recruiting efforts targeted different student audiences. We bought GRE records and targeted minority groups within science majors related somehow to agriculture and agroecology. We were able to individually contact 41 students within that group, but we did not identify a student for our project from that group. In the national Agronomy meeting that occurred in Minneapolis (Nov. 2015), we recruited students during the career fair. We prepared flyers with the information regarding the NNF program and the PhD concentration in Agroecology. We contacted several students during the career fair and followed up in the ones who were interested. In addition to the recruiting in Minneapolis, we also participated in the student career fair sponsored by the University of Florida in October 2015. In addition, we gave a seminar at Florida International University and contacted several potential students interested in the NNF program in that institution. Recruiting efforts also included advertising in mailing lists (Ecolog) and direct contact with graduate programs in Agronomy and Soil Science across USA. After all this effort, we have two students committed to start the PhD. The first student is Erin Doughtie. Erin is finishing her MS degree in UK and already have international experience in Kenya. Erin will start her PhD program in the Spring 2017. The second student committed is David Jaramillo. David has hispanic background and is a US citizen. David is finishing his MS degree at the University of Florida and will start the PhD in the Summer 2017. For the third assistantship, we have three candidates that we are considering. We should reach a decision in July, with potential to start the program in Fall 2016. All the students are committed with the International component of our project and with the concentration in Agroecology. Changes/Problems:We haven't changed the project. We did have difficult time identifying students from minority pools that have good credentials and are interested in Agriculture and Agroecology. We dedicated a major portion of our time in the recruitment. After all the efforts, we were able to identify two students that are already committed to start the PhD. The third student we are selecting from a pool of three candidates. What opportunities for training and professional development has the project provided?The project has provided opportunity for training in International Agriculture. We developed and approved the curriculum of the PhD concentration in Global Systems Agroecology. We also developed agreements with foreign Universities including the following countries : Brazil, Peru, France, Turkey, UK, Australia. We are committed to develop further collaboration with other foreign institutions to broad the opportunities for our graduate students and programs. How have the results been disseminated to communities of interest?We have advertised the PhD concentration in Global Systems Agroecology for a broader audience of students. Since we are still recruiting the students, we do not have results from their research project to report. What do you plan to do during the next reporting period to accomplish the goals?The major emphasis will be to start the program for the three students. Two of them are already committed, and the third one will be selected from a pool of candidates that we already have. Their research project will also commence as soon as they enter the program, in order to have them on track for graduation by the end of this project. Finally, we will start contacting the foreign institution where they will develop the internship.

    Impacts
    What was accomplished under these goals? We are still in the initial phase of the project. We dedicated most of our time to recruit students with excelent credentials and also to develop the PhD concentration in Global Systems Agroecology. We already recruited two students from minority pools, and we are trying to recruit the third one from those pools as well.
