Memorandum for the Petitioners | 100 and brought back to one point five (1.5) metric tons per hectare. And you don’t need extensive calculation or thinking or embedding an algorithm to say that that definitely is a very important and decisive threat to food security. Flooding will increase crop losses. And considering that rice is a water-loving crop ~ in fact, Your Honors, in an era of climate change and water scarcity, irrigated rice needs something like ten thousand liters of water to generate one (1) kilo of mill rice. However, while we are breeding varieties of rice that can survive under flooded conditions for a prolonged period of time, we're not yet there, because the floods that we are experiencing are not only getting longer, they're getting more violent in terms of water flows and water velocity.446 are 8.83. Further, the IPCC has stated that “all aspects of food security potentially affected by climate change, including food access, utilization, and price stability.”“*” According to the IPCC, changes in temperature and precipitation have negatively affected terrestrial crop production (wheat and maize),“* as well as fishery productivity, due to fish migrating to cooler and deeper waters in response to warming ocean temperatures.” Expert witnesses Drs. Laura David, Maria Lourdes San Diego-McGlone, and Porfirio Alifio, all professors at the Marine Science Institute of the University of the Philippines-Diliman, discussed this at length in their presentation before the Honorable Commission.*° 8.84. These impacts will become more widespread and severe in the coming years, but even in the near term the impacts on global food security could be devastating. For example, the IPCC projects that 10% of the impacts on food security under a 2°C warming scenario would yield losses of more than 25% in the period 2030-2049, with even greater losses expected after 2050.“ For low-latitude countries like the Philippines, there is high confidence that crop production will be “consistently and negatively” affected by climate change in a 2°C warming scenario and fishery production will also decline.*” “46 Id. pp. 137-138. “#?
