    Local urban coastal cities are most vulnerable to the impacts brought about by climate change. Very little attention, however, had been given to the role of coastal cities, including Navotas City, to the achievement of food security in urban centers like Metro Manila. A unified plan of action and a sustainable food security program are imperative given the unpredictability of climate change and the growing urban populations, which result in an increasing demand for a sustainable source of nutritious and affordable food. This study looked into developing a sustainable food security program designed to mitigate the impacts brought about by climate change on food availability, access, utilization, and stability; and how these affect Navotas City’s food security. Data from literature reviews and agency reports were validated by key informant interviews and focus group discussions to achieve the aforementioned objective

    Climate Risk Analysis on the Food Security in Saguday, Quirino Province

    Saguday is a 5th-class municipality of Quirino Province. The nine barangays of Saguday namely – La Paz, Cardenas, Salvacion, Santo Tomas, Rizal, Tres Reyes, Dibul, Cardenas and Gamis – are all vulnerable to climate change and calamities, not only because of the scarce resources of the municipality, but also due to the geographical and climatological condition of the area. Rainfall rates are projected to increase due to climate change and there will also be some likely increase in mean maximum tropical cyclone wind speed due to the projected 21st century warming (Knutson et al., 2010). Its location in Quirino Province places Saguday within the biggest watershed area in the region. Both observational data and modelling projections show that with climate change, wet regions will generally (but not universally) become wetter. Crop production in Saguday may also be affected biophysically by meteorological variables including rising temperatures, changing precipitation regimes, and increased atmospheric carbon dioxide levels. As socio-economic factors influence responses to changes in crop productivity with price changes and shifts in comparative advantage, a 5th class municipality with scarce resources can be very vulnerable to the effects of climate change. This present study identifi es the climatological problems and difficulties confronting the municipality

    Urban Organic Farming for Diversified Agriculture

    Get PDF
    Urban organic farming had been shown in previous projects as well as the present one to have the potential of addressing the fundamental requirements of food security by addressing issues of availability since production is just in the vicinity, which also addresses the carbon footprint of food production because food need not be transported to far distances. The use of organic methods also contributed to increased food safety. More importantly, the practice of urban agriculture empowers local residents in the stewardship, specifically of their barangay’s green spaces and more broadly the whole urban environment (see Mogk, Kwiatkowski, &Weindorf, 2010). However, to make full use of the potentials of urban agriculture, the local government should integrate these initiatives in urban planning and framing of policies and regulations (see Mougeot, 2006 and Mukherji& Morales 2010)

    Urban Hydroponics for Diversified Agriculture: Part II

    Get PDF
    Achieving food security in urban communities proves to be a challenging task. The inability of cities to produce its food requirement means that food has to be imported from faraway places. Traffic congestion, rising fuel prices, and poor road infrastructure have caused problems in transporting food from farms to markets. The increase in rates of spoilage of perishable vegetables and in transportation costs is a food security issue that needs to be addressed

    Climate adaptation, technological self-reliance, and the developing world: Evidence from an emerging economy

    Despite good intentions, development assistance from donor countries are often underutilized by recipient nations due to weak absorptive capacities. Addressing this issue has become more imperative with recent international accords engendering the rapid influx of massive climate assistance funds into the developing world. Particularly, interventions are focused on addressing exceptional vulnerabilities of developing nations to near-term climate impacts, for example, devastating typhoons and associated hazards. Fundamental to this effort is establishing the necessary technology infrastructure for generating quality climatic and environmental information, which serves as valuable logistical support for Disaster Risk Reduction and Management plans and activities. Efforts to address this in developing countries, however, are often sluggish or met with gridlocks. This is despite following internationally-prescribed best-practice roadmaps, conditioned by access to foreign aid. The Philippines’ experience in implementing its technological self-reliance policy provides a possible framework for overcoming this difficulty. Contribution analysis, through dissecting and examining the policy implementation period of 2010–2015, reveals that a more cooperative sociopolitical landscape, engendered by the visibility of a program “championing” the country’s drive to break away from technological dependence, can provoke rapid technological catch-up, bringing about the desired transformation. © 2017 by De La Salle University

    Some effects of gamma radiation on the cigarette beetle, Lasioderma serricorne (F.) (Col. Anobiidae)

    The lethal and sterilizing effects of gamma radiation on the different metamorphic stages of L. serricorne were investigated. The test organisms were irradiated using a Co-60 gamma cell 220 irradiator with dose rates ranging from 173.4 to 194.2 kr/hr. The doses used were from 40 to 500 kr. Death was recorded if there was complete lack of response to tactile stimuli. Unhatched eggs were also considered dead. Mild etherization was used to induce the adults to extrude their genitalia so that their sex could be identified. Complete mortality within 24 hours was observed in the adults and pupae exposed to 400 kr, the larvae at 350 kr while no eggs hatched following exposure to 90 kr. No viable progeny was produced by adults exposed to 10 kr. The females were found to be more radiosensitive than the males. Although the great majority of the papers on L. serricorne concern infestation of tobacco, this species has probably the most varied taste in food of all stored product pests. Howe (1) reported about 40 infestations of plant materials ranging from dried crops to upholstery and books. It has also been noted as a herbarium pest (2). Otanes (3) and Metcalf et al. (4) wrote that it is the most important pest of tobacco in factories and cigar stores and causes considerable damage to other products as well

    No full text
    A simple and straightforward approach in the synthesis of highly active palladium nanocatalysts aided by biological buffers is herein presented. Using HEPES and Tris as the buffers, highly active sub-10 nm palladium nanoparticles were formed. These nanocatalysts exhibited high catalytic activity toward the reduction of nitroaminophenol isomers. Moreover, this approach involves ambient conditions and a one-pot setup void of harsh reagents. The presented method highlights practicality without compromising catalytic activity which is very attractive for routine preparation of palladium nanocatalysts. © 2017, Chiang Mai University.

    Species invasion was identified as one of the main factors in biodiversity loss and it has been the subject of multilateral agreements among countries under the Convention of Biological Diversity to protect the natural environment. One of the more cryptic but potentially devastating invasion events of recent times in the Philippines is the one caused by species of Pterygoplichthys or locally known as janitor fish. In this paper, we provide an appraisal of this invasion event in several areas we surveyed were Pterygoplichthys spp. has been introduced. We performed: 1) a taxonomic survey of collected Ptmygoplichthys specimens in localities in the Luzon Island; 2) an ecological survey of waterways in the localities; and 3) field interviews of peopl e during the visits. Our results show that the eight sites visited have been invaded by Pterygoplichthys spp. Invasion stages range from Stage II to Stage V. The invasion situation at each site is discussed. In this paper, we also offer insights on a multiple founding event for Pterygoplichthys spp., as well as its implications to local policies on management and mitigation on species invasions

    Sequence-dependent cluster analysis of biomineralization peptides

    No full text
    A reliable and statistically valid classification of biomineralization peptides is herein presented. 27 biomineralization peptides (BMPep) were randomly selected as representative samples to establish the classification system using k-means method. These biomineralization peptides were either discovered through isolation from various organisms or via phage display. Our findings show that there are two types of biomineralization peptides based on their length, molecular weight, heterogeneity, and aliphatic residues. Type-1 BMPeps are more commonly found and exhibit higher values for these significant clustering variables. In contrast are the type-2 BMPeps, which have lower values for these parameters and are less common. Through our clustering analysis, a more efficient and systematic approach in BMPep selection is possible since previous methods of BMPep classification are unreliable
