“…The latter is foreseen to be more affected in both wet and dry cropping season. However, slight changes in cropping calendars may affect the yield significantly (Lansigan et al 2007). A direct solution for possible water shortages is to store the surplus water in November to December, but may need reservoirs for water storage and even flood mitigation.…”

“…These estimates, however, are based on the potential irrigation water from Abuan watershed. In reality, most of the corn fields in the study area are rainfed (Lansigan et al 2007), but gradually being modernized because of the agriculture modernization plan (including irrigation) in the Philippines (Inocencio et al 2016). For comparison, assuming the actual irrigated croplands as 1/10 of the total, the croplands at risk from CC-LULCC would be lower at 8.98%.…”

One of the main impact areas of climate change (CC), and land use and land cover change (LULCC) is the hydrology of watersheds, which have negative implications to the water resources. Their impact can be indicated by changes on streamflow, which is quantifiable using process-based streamflow modelling of baseline and future scenarios. Here we include the uncertainty and associated risk of the streamflow changes for a robust impact assessment to agriculture. We created a baseline model and models of CC and LULCC “impact scenarios” that use: (1) the new climate projections until 2070 and (2) land cover scenarios worsened by forest loss, in a critical watershed in the Philippines. Simulations of peak flows by 26% and low flows by 63% from the baseline model improved after calibrating runoff, soil evaporation, and groundwater parameters. Using the calibrated model, impacts of both CC and LULCC in 2070 were indicated by water deficit (− 18.65%) from May to August and water surplus (12.79%) from November to December. Both CC and LULCC contributed almost equally to the deficit, but the surplus was more LULCC-driven. Risk from CC may affect 9.10% of the croplands equivalent to 0.31 million dollars, while both CC and LULCC doubled the croplands at risk (19.13%, 0.60 million dollars) in one cropping season. The findings warn for the inevitable cropping schedule adjustments in the coming decades, which both apply to irrigated and rainfed crops, and may have implications to crop yields. This study calls for better watershed management to mitigate the risk to crop production and even potential flood risks.

“…Next to rice, corn is the second most important crop (31,32). About 24 million Filipino families rely on corn as a primary source of income (31,33). Yellow corn is the primary source of material for the animal feed industry and other manufacturing sectors, and white corn is an important substitute for rice (31).…”

AbstractThis study attempts to assess the risk of mycotoxins (aflatoxins and fumonisins) contamination on corn in the Philippines under current and projected climate change conditions using fuzzy logic methodology based on the published range of temperature and rainfall conditions that favor mycotoxin development. Based on the analysis, projected climatic change will reduce the risk of aflatoxin contamination in the country due to increased rainfall. In the case of fumonisin contamination, most parts of the country are at a very high risk both under current conditions and the projected climate change conditions.

“…Concrete is one of the most widely used construction material in the construction industry because of its high compressive strength, long service life and low cost [1]. The use of concrete ranges from its utilization in the construction of buildings to its versatility in highway construction particularly in the construction of roadways [2]. In addition, a vital role in the development of infrastructures including residential, commercial and industrial sectors is attributed to the performance of concrete [3].…”

Waste disposal is one of the issues that plague the society. Philippines is an agricultural country due to its strategic location in the tropics. Because of this nature, the agriculture sector tends to produce a huge amount of waste that if not disposed properly could pose a threat to the society and to the environment. With the advancement of technology, it has been a challenge for researchers to improve the quality of construction materials that is used in the industry. Studies have been performed on the possibilities of incorporating agricultural wastes to various construction materials as a form of waste diversion. In order to address the problem with agricultural wastes as well as to improve the property of construction materials, a study on coconut waste and eggshell waste was conducted as a constituent in concrete brick production. In this study, the density, compressive strength as well as the water absorption of concrete bricks with coconut charcoal powder (CCP) and eggshell powder (ESP) as replacement for fine aggregates and cement was conducted. Different mix ratios (0%, 2.5%, 5%, 10% CCP with a constant value of 5% ESP in each mix ratio) were carried out and the results were compared to a control sample. From the results of the density test, the concrete bricks with 5% CCP and 5% ESP was the lightest at a density of 1678.184 kg/m3, it also showed the least water absorption at 8.58% and exhibited the highest compressive strength at 17.5 MPa.
