    Editorial Preface

    The Southeastern Philippines Journal of Research and Development has, over the years, provided an important niche for the works of scholars on aspects of Mindanao region’s socio-economic development. The current edition continues and develops this significant role of the journal in responding to the needs of Mindanao, Philippines. The articles in this edition deal with issues from humanities, and biology.

    In the first article in this edition, Dr. Rodney C. Jubilado, Chair of the Humanities Division of the University of Hawaii at Hilo, United States of America, provides a comparative analysis of the ergative and accusative structures of Philippine languages, namely, Isamal, Cebuano, and Filipino. The varieties of these languages are the ones used in the Island Garden City of Samal, Philippines. The findings of the study of Dr. Jubilado have a significant contribution to the preservation of Philippine indigenous languages.

    Staying with the scholarship on socio-cultural studies, Dr. Takashi Tsuji of Saga University, Japan, contributes to the discourse on Philippine literature and research as he investigates Philippine folklore of saltwater crocodiles. Based on the eight types of crocodile folklore, Dr. Tsuji specifically examines how Filipinos, particularly from Palawan and Mindanao, have recognized crocodiles in the past and coexisted with them for hundreds of years.

    This issue also highlights the articles from the field of biology: Dr. Samuel Herbert T. Mamora of the University of Southeastern Philippines analyzes the floristic composition and diversity of weeds in organic rice fields in Langkong, Mlang, North Cotabato, Philippines that could lead to a better understanding of the rice agroecosystem and improvement in weed management; Glenn Vallespin of the University of the Philippines Mindanao and his counterparts from Caraga State University, Butuan City, Philippines examine an in-depth relational analysis of human-induced stress and habitat contraction with bat species in the neighboring roosting sites in Caraga State University in Butuan City; and Lawrence P. Deligero of Davao Medical School Foundation and Hilario L. Wong, Jr. of the University of Southeastern Philippines explore the alternative morphometric characters that could be used to estimate the larval age of red palm weevil (RPW), Rhynchophorus ferrugineus.

    Reviewed by international scholars, the collection of articles in this issue will not only facilitate and enlarge our consciousness of the region’s uniquely rich culture, but more importantly, will contribute to the creation of projects geared towards the socio-economic development of Mindanao.

    Editorial Preface

    The contents of this Special Issue of the Southeastern Philippines Journal of Research and Development focuses on food and agriculture: technologies to improve production, detection and management of plant and animal diseases, remedying ill conditions of both crops and animals, locating the most suitable areas to plant crops, and most importantly finding smart, innovative and sustainable means to enhance the country's agricultural sector.  In a nutshell, the authors of the studies in this issue forward ways on how we could further live and survive, as the need for food is heightened by a health crisis that, as everyone by far already knows, has struck the world's systems.

    Conducted before the COVID-19 pandemic became a byword to most Filipinos, these studies “ brought in large part by agricultural scientists, engineers and student researchers from USeP “ are products of a scientific conference themed Sustainable Agroecosystems and Emerging Innovations (SAEI). Presented in this issue are eleven discussions and contributions on grassroots-based innovations, clean energy, food preservation, crop health, among other agricultural technologies and discoveries. In a way, these researches are part of the pursuit to address a nation's health and survival.

    A question on the adequacy of food cannot be pinned down to a mere Yes or No without further explanation. As conference organizers and Journal editors, we hope that these studies would make the best sense as answers to a curiosity raised in the time of pandemic: do we have enough food?

    We hope then that the individual articles prod readers to recognize the importance of agriculture and how it responds to the needs of the future. Though the pandemic creates significant blows to the economy, our resources, and people's lives, the promise of agricultural science continues, engendering ideas and delivering technologies to communities. The future is assured that scientific curiosity and advancements in food science and engineering will find ways to take care of humanity's needs. Truly, there is no better time than now to read and be reminded of the possibilities of hope that these researches bring.

    Here is the rundown of articles in this Special Issue, covering agroecosystems and innovations:

    An integration of solar-powered pumps in the irrigation system in rice-fish farming, by Ryan M. Abenoja; Development of a provincial land suitability map of solar-powered irrigation system for local farmers and LGUs, by Sheila C. Cogay, Ireneo P. Amplayo, Roland R. Bayron and Ruben V. Cantones; Effect of absorbent polymer in improving moisture retention in the soil and on the growth response of banana, by Ruel F. Tuyogon;

    A study on the physicochemical characteristics of soils under cacao production, by Nelvin A. Villason and Dernie T. Olguera; Preharvest application of the compound 1-MCP on postharvest quality of banana, by Bryl I. Manigo and John Paul Matuguinas;

    An investigation of the potential of vermicompost drippings as foliar fertilizer for lettuce by Ulysses P. Besas, Sinneth Caniones and Larry V. Aceres; Testing of a locally made vermitea vortex brewer, by Kzyl Mae S. Albiso;

    An examination of the storage quality of fresh yacon, by Joyce C. Limbaga and Katherine C. Israel; and, articles dealing with diseases, such as Identification of the severity of anthracnose in Carabao mangoes using the DigiMango mobile app, by Louie G. Simbajon, Gia C. Mata, Dessa L. Ybanez and Dhally A. Ilisan; plus a Survey on the extent of usage of traditional medicine in controlling parasites in native chicken, by Hyde D. Nadela. We would like to give a special mention to Belly T. Dionio, Carlo Jun M. Bacoba, Cecirly G. Puig and Fernan A. Ramos's First Report on Fusarium heart rot on pineapple in South Cotabato and Davao City.

    We are grateful to the specialists and experts who shared their insights during the SAEI International Research Conference and played critical roles in the vetting process.

    May this collection of articles not only facilitate and add to the academic community's knowledge on agricultural science and engineering but also contribute to the creation of development projects to impact marginalized communities in Mindanao and the country as a whole. Readers interested in contributing articles along the theme of sustainable agroecosystems and emerging innovations, as well as the other themes reflecting the University's research agenda (see Information for Authors, last page), are highly encouraged to submit their manuscripts for review (for a 2021 Journal release date).

    With our readers support and future contributions reaching our editors desks, the SPJRD shall strive to carry on creating a niche for scientific research from the peripheries.
