Proposed Topic for Side-Event at COP24, Thai Pavilion, Poland

Side Event Title : World Soil Day: Sustainable Soil Management, and Food Security

Responsible person/Org: Ms. Wichita  Intharasri, Land Development Department, Ministry of Agriculture and Cooperatives

Format of the side event: Food Security

Duration: 5 December 2018

Rationale

Soil is a natural resource, and is non-renewable on a human timescale. Soils are also the foundation of agricultural development and ecosystem sustainability, and provide the basis for food, feed, fuel and fiber production, clean water, nutrient cycles, organic carbon stocks, one-quarter of global biodiversity, and also serve as a platform and source for construction. Our soils are in the risk. Human activities are main source of soil pollution. It is in our hands to adopt sustainable soil management practices.

In 2013, the United Nations General Assembly declared 5 December of every year the same date as His Majesty’s Birthday as World Soil Day in recognition of His Majesty’s tremendous efforts and dedication in the field of soil resources development, in particular agriculture development.

World Soil Day is a day dedicated to soils aims to connect people with soils and raise awareness on their critical importance in our lives. World Soil Day is an important tool for promoting education about soil resources, awareness of soil degradation and campaigning to prevent and control soil pollution at all levels continuously and practically

Land Development Department and Rice Department, Ministry of Agricultural and Cooperatives, Thailand are currently planning to promote climate-smart and environment friendly practices for agricultural waste management in the North, Central plains, and North-East regions of Thailand. Main focus of their operational plans is to encourage farmers stop burning and utilize their agricultural residue (i.e. maize stalk, rice straw, and palm kernel shell) towards climate-smart and environment friendly practices including the organic compost and bio-charcoal. Although the technical knowledge of the Government on production of organic fertilizer has been transferred to farmers, they are facing several challenges to achieve their plans and targets.

In 2015, estimated 50 million tons of rice straw and stubble (about 5 ton/ha/year) are generated from 10.3 million ha of rice paddy fields [1, 2, 3, 4]. Burning agricultural residue heavily contributes to several air pollutants including polycyclic aromatic hydrocarbon and particulate matter which are harmful to human health and losses of nutrients including Nitrogen, Phosphorus, Potassium, or micro nutrients. Moreover, burning pollutes land and decreases soil fertility in the long term [4].  Agricultural residue is therefore problematic in the Thai agricultural sector. Alternatively, incorporating (or plowing) agricultural residue is recommended for recycling nutrients and soil conservation [3]. Although incorporating rice straw in the paddy fields is an environmental friendly practice, International Rice Research Institute (IRRI) revealed that it would dramatically increase methane emissions from the soil, compared to rice cultivation without incorporation of rice straw in continuous flooding fields [4]. A study on life cycle assessment of rice production with different straw management practices indicates that a partial removal of rice straw is recommended as it is more climate and environmental friendly practices than complete removal, incorporation and burning practices.
