Developing a framework of gastronomic systems research to unravel drivers of food choice by Cuevas, Rosa Paula, de Guia, Annalyn, Demont, Matty

“…We develop a framework of “gastronomic systems research” (GSR) to understand culture-specific consumer food choice, and contextualise it to a target population of urban, middle- to high-income Filipino consumers to assess the domestic niche market potential of traditional rice varieties in the Philippines. The GSR framework is contextualised through expert elicitation involving chefs and nutritionists, and validated through a consumer survey conducted during a food exposition. …”

Carbon dioxide equivalent emissions of newly developed rice varieties by Taghavi, Seied Mohsen, Mendoza, Teodoro C., Acero Jr, Bart, Li, Tao, Siddiq, Sameer Ali, Yorobe Jr, Jose, Li, Zhikang, Ali, Jauhar

“…In this study, we compared the gross CO2e emission of two newly developed green super rice (GSR) varieties with elite hybrids and nationally released farmer-cultivated varieties from production to post-production in the dry and wet seasons in Laguna, Philippines. The average gross CO2e emission was 17.9 tons CO2e ha-1 or 2.98 tons CO2e ton-1 rice (production 82%, post-production 18%). …”

Measurement of isotopically‐exchangeable Zn in Zn‐deficient paddy soil by Izquierdo, M., Impa, S.M., Johnson-Beebout, S.E., Weiss, D.J., Kirk, G.J.D.

“…We explored the use of stable isotopic dilution assays for assessing Zn dynamics in submerged paddy soil with two types of strongly Zn‐deficient soil for rice cultivation in the Philippines. We optimized the isotope enrichment, electrolyte and equilibration time to measure isotopically‐exchangeable Zn (E‐values) without changing redox conditions. …”

Interactions between senescence and leaf orientation determine in situ patterns of photosynthesis and photoinhibition in field-grown rice by Murchie, Erik H., Chen, Yi-zhu, Hubbart, Stella, Peng, Shaobing, Horton, Peter

“…Two varieties (IR72 and IR65598-112-2 [BSI206]) were grown in the field in the Philippines during the dry season under highly irrigated, well-fertilized conditions. …”

Supplemental ultraviolet-B radiation does not reduce growth or grain yield in rice by Dai, Qiujie, Peng, Shaobing, Chavez, Arlene Q., Miranda, Ma. Lourdes L., Vergara, Benito S., Olszyk, David M.

“…To address the response of rice to UV‐B, we conducted an intensive and extensive series of field experiments from 1992 to 1995 documenting the effects of supplemental UV‐B (simulating approximately 20% ozone depletion for the Philippines), using irrigated rice cultivars under tropical conditions. …”

Selection for Tolerance to Low Temperature-Induced Spikelet Sterility At Anthesis in Rice by Khan, D.R., Mackill, D.J., Vergara, B.S.

“…Individual plants were grown in small pots in the glasshouse room of the phytotron at the International Rice Research Institute, Los Baños, Philippines. Cold tolerance was measured as percent spikelet fertility of plants subjected to low day/night temperatures (20/20°C or 21/21°C) for 5 days at anthesis in the phytotron. …”

Multicriteria and critical threshold value analyses in assessing sustainable forestry: model development and application by Mendoza, G.A., Hartanto, H., Prabhu, Ravi, Villanueva, T.

“…These models were applied in a case study involving a community-managed forest in the Philippines. Feedback received from the assessors indicate that the models were found to be useful, transparent, and helpful tools in generating relevant sets of C&I and in evaluating these C&I with respect to overall forest sustainability.…”

Constraints and opportunities for better silvicultural practice in tropical forestry: an interdisciplinary approach by Walter, B.B., Sabogal, C., Snook, Laura K., Almeida, E. de

“…To illustrate this approach, this paper presents three case studies of research on tropical silviculture practice from each of Philippines, Brazilian Amazon and Mexico. Findings from these studies indicate that a variety of factors may influence whether or not silvicultural practices are adopted. …”
