“…As a result, fields are constantly flooded throughout the vegetation period, providing optimum conditions for methanogenesis. In reality, infrastructural constraints, such as the unavailability of water pumps, prevent unlimited access to irrigation water (Inocencio & Barker, 2018). Consequently, this study very likely overestimates the number of days a field is CF and thus also seasonal CH 4 emissions.…”

Greenhouse Gas Mitigation Potential of Alternate Wetting and Drying for Rice Production at National Scale—A Modeling Case Study for the Philippines

Worldwide, rice production contributes about 10% of total greenhouse gas (GHG) emissions from the agricultural sector, mainly due to CH4 emissions from continuously flooded fields. Alternate Wetting and Drying (AWD) is a promising crop technology for mitigating CH4 emissions and reducing the irrigation water currently being applied in many of the world's top rice‐producing countries. However, decreased emissions of CH4 may be partially counterbalanced by increased N2O emissions. In this case study for the Philippines, the national mitigation potential of AWD is explored using the process‐based biogeochemical model LandscapeDNDC. Simulated mean annual CH4 emissions under conventional rice production for the time period 2000–2011 are estimated as 1,180 ± 163 Gg CH4 yr−1. During the cropping season, this is about +16% higher than a former estimate using emission factors. Scenario simulations of nationwide introduction of AWD in irrigated landscapes suggest a considerable decrease in CH4 emissions by −23%, while N2O emissions are only increased by +8%. Irrespective of field management, at national scale, the radiative forcing of irrigated rice production is always dominated by CH4 (>95%). The reduction potential of GHG emissions depends on, for example, number of crops per year, residue management, amount of applied irrigation water, and sand content. Seasonal weather conditions also play an important role since the mitigation potential of AWD is almost double as high in dry as compared to wet seasons. Furthermore, this study demonstrates the importance of temporal continuity, considering off‐season emissions and the long‐term development of GHG emissions across multiple years.

“…Problems involving lacking funds for irrigation systems [11] and the financial support systems [12] of the farmers are also part of the concern of the political factors affecting the rice industry. Support from the respective government agencies is needed to understand and perform the solutions and resolve the existing problems identified.…”

Rice industry in the Philippines is beset with environmental, social, and economic concerns resulting in low farmer incomes, lack of food security and meager competitiveness. This study aimed to develop inclusive interventions on rice trading practices involving smallholder farmers. Primary data were derived from baseline interviews from farmers, traders, millers, wholesalers, and retailers to assess trading practices involved in the chain. Stakeholder consultations were also conducted to validate the findings and identify strategies for the initiatives. Based on the results, the major challenges identified include high production and marketing costs of paddy attributed to high material inputs and labor costs. This leads to a low profit margin for smallholder farmers. This gap relates to poor market linkage that limits the ability of farmers to receive higher prices for their produce. Interventions involving the improvement of marketability through market innovation were prioritized to address the gap. Recommendations concerning reducing institutional barriers towards smallholder farmers was provided to broaden adoption of inclusive trading practices and foster a more equitable and sustainable rice value chain.

“…Some solutions were investigated; however, the issue persists. Despite such concerns, there are ways to enhance water utilization in terms of water management and water productivity [3]. A means of addressing this is through automated irrigation.…”

The objective of project is hinged on two essential features (the time and the amount of water pressure). The automated plant irrigation and monitoring system was created efficiently get things done for farmers. This capstone project used an Arduino Board. The features of the system are based on identified needs of Ladroma's Farmland, situated in Banagbanag, Montevista, and Davao De Oro. The system was configured to measure the following (temperature, humidity, water level, soil moisture and control the flow of water) either manually or automatically. Moreover, it can also sense soil moisture and supply the exact amount of water needed. The system aims to set up a wireless sensor network to monitor the soil moisture which will send information to the system to start the water pump if the soil dries up. Furthermore, the proposed irrigation system will reduce the hassle of looking after plants. Thus, improving farmer efficiency. The system will also provide a real-time monitoring status relative to plant irrigation.
