THAI NGUYEN UNIVERSITY UNIVERSITY OF AGRICULTURE AND FORESTRY JOHN LESTER M LAGANSUA ENVIRONMENTAL MANAGEMENT PRACTICES APPLIED IN INTENSIVE FARMING BY SELECTED RICE FARMERS IN VICTORIA, LAGUNA, PHILIPPINES BACHELOR THESIS Study Mode: Major: Faculty: Batch: Full-time Environmental Science and Management Advanced Education Program Office 2015-2018 Thai Nguyen, 15/11/2018 DOCUMENTATION PAGE WITH ABSTRACT Thai Nguyen University of Agriculture and Forestry Degree Program Bachelor of Environmental Science and Management Student Name John Lester M Lagansua Student ID DTN1454290083 Thesis Title Environmental Management Practices Applied in Intensive Farming by Selected Rice Farmers in Victoria Laguna, Philippines Supervisors Assistant Professor Maricel A Tapia Dr Nguyen Huu Tho Supervisors’ Signature Abstract: Intensive farming has been seen as a problem to the environment mainly because of the amount of chemical used There are certain environmental consequences of intensive farming and these are loss of natural habitats and the associated impact on the biodiversity, soil degradation such as erosion, depletion, and pollution (air and water) and especially it contributes to some climatic changes The study aims to assess the environmental management practices applied in intensive farming by selected rice farmers in three barangays in Victoria, Laguna, namely, Masapang, San Benito and San Roque The study employed mixed methods which gave emphasis to both qualitative and quantitative aspects As for the qualitative part, the study conducted the FGD wherein in-depth interviews were done The quantitative part, on the other hand, utilized survey questionnaire to determine the socio-demographic and socio-economic profile of the respondents, and their agricultural and environmental management practices Descriptive statistics were used to analyze quantitative data, which was given context through qualitative data analysis Results revealed that different agricultural practices were practiced throughout the crop cycle, including manual or hand weeding, puddling of soil, application of urea fertilizer, application of complete 14-14-14 fertilizer, application of herbicide, spraying of pesticide, rice straw burning, flood irrigation and sprinkler irrigation method Associated with these practices are the environmental/ecological impacts caused by intensive farming on air, water, soil, biodiversity and climate change The research revealed that the most experienced impacts of the respondents are climate and air impacts, wherein climate change and foul smell were experienced by 100% of the total number of respondents As for the management practices, most farmers already perform mitigating measures, which were perceived to be effective However, not all the environmental management practiced tackles the environmental impacts that were determined Among those different environmental sectors, climate and air management practices really target the actual problem of environmental pollution and perceived to be effective because of ii improvements observed On the other hand, management practices for the associated water pollution from intensive farming (such as eutrophication and water contamination) did not seem to address the actual problem as the strategies implemented were for conservation purposes only Keywords: Intensive farming, Farm characteristics, Agricultural practices, Environmental Impacts, Environmental management practices Number of pages: 109 Date of November 15, 2018 submission: iii ACKNOWLEDGEMENT This odyssey would not have been this successful without the help and support of my home university, Thai Nguyen University of Agriculture and Forestry especially all the staff and professors of the Advanced Education Program’s office who have showed their support in accomplishing this study, and the director of the International Program’s Office, Dr Duong Van Thao for giving me the opportunity to explore and to step out of my comfort zone by studying abroad Also, I want to thank the University of the Philippines Los Baños and all the staff especially Chancellor Fernando C Sanchez, Jr for allowing me to conduct my undergraduate thesis in the host university I sincerely thank Asst Professor Maricel A Tapia of Department of Social Forestry and Forest Governance, College of Forestry and Natural Resources, University of the Philippines Los Baños for expressing her willingness to supervise me Her substantial comments, suggestions and obliging censures are greatly valued and appreciated I would also like to thank my Vietnamese adviser Dr Nguyen Huu Tho, Director of Office of Research and International Affairs, Thai Nguyen University of Agriculture and Forestry for his support and guidance Without their assistance and determination to be involved in every step of the way throughout its process, this paper would have never been accomplished I also want to acknowledge Mr Emmanuel C Atas, municipal agricultural officer and Mr Apolinario H dela Cruz, secretary of the Sangguniang Bayan of the municipality of Victoria Laguna for providing all the documents needed for this research, including the list of all rice farmers in their town, and the list of agriculture-related policies and regulations Also, I want to extend my deepest appreciation to ninety (90) rice farmers from three selected barangays of Victoria; Masapang, San Benito and San Roque who wholeheartedly participated during the process of data gathering iv I would also like to show gratitude to my Vietnam buddies; Luis, Enzo, Jessica, Pau, Joy, Vea, Kristina and Francina, to my “tropang tinder” and to my “forever tropas”; Jai, Min, Angge, Cha, and Rona for all the encouragements and for somehow making this journey light and fun despite of all the outbursts and stressed moments we’ve shared together A special mention to a very special person in my life, Allysha Joy de Castro for being my number one supporter in everything I do, for being one of the sources of my happiness every time I feel depressed in life; and for not leaving me since the beginning of this research study until the end I would also like to encompass my deepest and sincerest appreciation to my family for their endless and abounding love, help, guidance and support as I conquer every challenge in my life I will be forever grateful to my parents, Lodie C Lagansua and Rachille M Lagansua who have been supporting me not just financially but emotionally and spiritually; I salute the both of you for all the sacrifices you have made just to assure that I will have a great future ahead of me Also, thank you for all the experiences, life-lessons and opportunities that have made me who I am today Most importantly, none of these would be possible without the help, care and unending love of the Almighty God who has been my shield in every mishap that I had experienced in life Truly God has blessed me with real good friends and loving family that serves as my greatest inspiration as I pursue my goals in life I am most thankful to God for giving me the opportunity, strength, ability, knowledge and wisdom to this kind of research study and be able to accomplish it competently, because with God, nothing is impossible I dedicate this milestone to everyone who has been part of my journey I must say that I am now ready to take another step as I explore the new chapter of my life Thank you so much and may our God bless us all!
