Abstract

Amid rapid urbanization and intensifying climate challenges, cities across Asia are embracing localized collaboration to pursue sustainable development. This study examines eco-urban diplomacy through sister-city partnerships between Jakarta–Tokyo and Surabaya–Kitakyushu, focusing on how urban farming and environmental horticulture advance climate resilience, social equity, and food security while contributing to SDGs 2, 11, 13, and 17.

Employing a mixed-methods approach, the research integrates geospatial analysis, policy review, and comparative literature. Findings show Jakarta–Tokyo collaboration promotes participatory urban farming and rooftop greening, enhancing food supply resilience and community well-being. Tokyo’s rooftop gardens and community plots have raised vegetable self-sufficiency from 4.27% to a potential 11.73%, strengthening resilience against supply disruptions. Meanwhile, Surabaya–Kitakyushu cooperation has achieved a threefold mangrove expansion (2000–2020), reduced waste volume by 20%, and introduced low-carbon, 3R principles through technology transfer and community-based programs.

Framed within polycentric governance theory, the study highlights how multi-level actors—municipal agencies, NGOs, communities, and universities—co-produce localized solutions. Urban agriculture emerges not only as a tool for climate adaptation but also as a platform for food justice and inclusive governance, addressing socioeconomic disparities in green space access. However, challenges such as financial constraints, communication gaps, and land insecurity persist, risking exclusion of marginalized groups.

This study concludes with tiered recommendations: short-term digital platforms and modular policy frameworks, medium-term co-funded grants and academic integration, and long-term standardized SDG indicators and joint governance bodies. These measures aim to institutionalize eco-urban diplomacy, turning symbolic partnerships into actionable, community-driven solutions for sustainable urban futures.
