Identifying new criteria for assessing the impact on the ecosystem generated by the establishment of Jerusalem artichoke crops on difficult and floodable soils
Abstract:Jerusalem Artichoke (Helianthus tuberosus L.) is a technical plant that manages to adapt very well to unfriendly environments, even in polluted or poor in nutrients soils and may serve in the near future as an important raw material for the food, chemical, and pharmaceutical industries. Furthermore, the plant is growing rapidly, producing large amounts of biomass and offers the possibility to be harvested up to 2 times a year, therefore presents a high potential to be used in the field of biofuel production.

“…Farmers often only do tillage and give manure to the geophytes for the first time before planting. Moreover, some geophytes are productive on marginal land or poor soil such as Jerusalem artichoke, cassava, 'porang', tannia and 'beneng' taro [21,22,35]. Almost all geophytes' crops are self-propagating, produce seedlings or are easy to propagate.…”

“…Geophytes have several advantages, such as being drought resistant [12][13][14], shade tolerant [15][16][17][18][19], easier to maintain [20], and more resistant towards animals than fruits. Moreover, some geophytes such as sweet potatoes, cassava, 'beneng' taro (Xanthosoma undipes K.Koch), 'porang' (Amorphophallus muelleri), and Jerusalem artichoke (Helianthus tuberosus L.) is thriving in the marginal land or poor soil [21,22].…”
Climate change affects farming activities, leading to a greater impact on food security. Indonesia has the potential for a wide variety of geophytes that can be utilized for food security. However, geophytes are underutilized crops, and our staple food is still dominated by rice. This study aims to explore the potential and obstacles in geophytes development for strengthening food resilience in Indonesia. The methods used in this research were surveying and interviewing 30 “porang” and “beneng” taro farmers between January 2022 to April 2022 to determine the potential of tuber development and its market regarding climate change. The research was carried out in Ciamis and Tasikmalaya Regency, West Java, Indonesia. The result shows that geophytes are low maintenance which helps in reducing GHG emissions. Unlike grains, geophytes are commonly shade-tolerant, more tolerant to drought stress, and resilient on marginal land. However, the difficulties in the geophytes crops development are the unstable prices, and the market sometimes is still very segmented and obscure. Meanwhile, to start planting geophytes on a large scale has an environmental problem and a significant investment risk for farmers, especially farmers with limited land and capital. Therefore, enrichment of geophytes planting under the state land stands may be an option for mitigating climate change and overcoming food security.
