Abstract. Mardiani MO, Kusumawati IA, Purnamasari E, Prayogo C, van Noordwijk V, Hairiah K. 2022. Local ecological knowledge of coffee agroforestry farmers on earthworms and their relation to soil quality in East Java (Indonesia). Biodiversitas 23: 3344-3354. Farmers manage their land-based on their understanding of biotic and abiotic factors, including soils, and how these factors affect crop growth and productivity. Their local ecological knowledge (LEK) is built upon intergenerational transfer and can use concepts that don’t directly match those of current science-based ecological knowledge. We explored farmer LEK related to soil organic matter management and earthworms in coffee-based agroforestry systems on volcanic slopes in East Java (Indonesia) by in-depth interviews with key informants and by surveying the concurrence of respondents, stratified by gender and age, with resulting statements. The term used in the local language for earthworms (‘cacing tanah’) included a range of species. According to 22% (n=48) of farmers, small earthworms (probably Pontoscolex corethrurus) are harmful to coffee trees because they eat the roots. Also, 54% (n=48) of farmers thought earthworms that eat soil cause a decrease in soil volume. However, according to the farmers, large earthworms (reddish-brown) can fertilize the soil by leaving their casts on the soil surface. Such worms are often found in coffee agroforestry systems. Farmers have little explicit knowledge of the activities of earthworms and their relation with litter as a source of food. Farmer knowledge of ecosystem services provided by earthworms can enrich current scientific literature and trigger a two-way dialogue.

Abstract

Abstract. Kusumawati IA, Mardiani MO, Purnamasari E, Batoro J, van Noordwijk M, Hairiah K. 2022. Agrobiodiversity and plant use categories in coffee-based agroforestry in East Java, Indonesia. Biodiversitas 23: 5412-5422. Beyond documenting the ethnobotanical knowledge by managers of complex agroforestry systems, the actual use of such knowledge in adapting to new circumstances and adopting new practices in dynamic farming systems has been described as ecological wisdom. Our study in the Kali Konto catchment of East Java (Indonesia) focused on an inventory of plants that are part of coffee-based agroforestry, their various types of use, and the role they play in the further integration of livestock into the local farming system. The 48 respondents mentioned, on average, 105 combinations of plant species and use categories for their coffee agroforestry plots. Across nine use categories (food, with spices and food wrapping as subcategories, animal fodder, medicine, construction, hedge/ornamentals, handicrafts, ritual uses), a total of 83 plant species (in 36 botanical plant families) were mentioned, with on average 2.18 reported uses per species. A small majority (56%) of the plant species was actively managed (and often planted); the rest were spontaneously established species.
