Introduction: Welang Basin
As one of the major river basins in East Java which has caused continuous flood challenges, Welang river basin is uniquely located in three administrative areas; Malang Regency, Pasuruan Regency, and Pasuruan City. The upstream region is located between Malang and Pasuruan Regency, the midstream is in the Pasuruan Regency, while the downstream is in Pasuruan City. Due to the various technical and social factors, it has been continuously flooding and caused a halt in the economic activities. Each section of Welang river, from upstream to downstream, has its own thematic challenges.
This page is dedicated to be the engagement platform between stakeholders in Welang River Basin and to share the Master Plan progress with wider audiences.
Pendahuluan: DAS Welang
Sebagai salah satu DAS utama di Jawa Timur yang kerap mengalami permasalahan banjir, DAS Welang secara unik terletak di tiga wilayah administratif; Kabupaten Malang, Kabupaten Pasuruan, dan Kota Pasuruan. Wilayah hulu terletak di antara Kabupaten Malang dan Pasuruan, bagian tengah di Kabupaten Pasuruan, sedangkan bagian hilir berada di Kota Pasuruan. Karena berbagai faktor teknis dan sosial, maka banjir seringkali menyebabkan terhentinya kegiatan perekonomian. Setiap ruas sungai Welang, dari hulu hingga hilir, memiliki tantangan tematiknya masing-masing.
Halaman ini didedikasikan untuk menjadi media interaksi antara pemangku kepentingan di DAS Welang dan untuk berbagi kemajuan Rencana Induk kepada khalayak yang lebih luas.
"Groundwater is invisible, but its impact is visible everywhere."
The UNESCO Water Resilience Challenge is a capacity-building program that challenges and inspires the next future leaders, especially students and young professionals from various backgrounds, to contribute ideas and concepts for their version of sustainable water management in biosphere reserve areas. This year marks the second year of the UNESCO Water Resilience Challenge with the theme of Groundwater.
Fifty selected participants from Indonesia and Vietnam will be put into teams, exchanging knowledge, mentored by professionals, and challenged to make the invisible visible! One winning team from each country will be invited to present their ideas at UNESCO International Conferences.
The Young Expert Programmes are open to Dutch Young Experts and Local Young Experts from any of the eligible countries. There is a difference in the selection process for both. Local Young Experts apply by approaching Dutch organisations, who conduct their own selection process, and Dutch Young Experts apply when new vacancies are posted online.

IFAD's current results-based country strategic opportunities programme (2016-2019) aims to support inclusive rural transformation so rural people can achieve sustainable livelihoods. We work to achieve this by providing financing and technical support to develop models for replication and scaling up by the government and others. The emphasis is on empowering marginalized groups including smallholder farmers and fisheries producers, women and woman-headed households, marginal communities and ethnic minorities in selected geographic areas, and youth.
We work with an international network of dam-affected people, grassroots organizations, environmentalists, human rights advocates and others who are committed to stopping destructive river projects and promoting better options.
We seek a world where healthy rivers and the rights of local communities are valued and protected. We envision a world where water and energy needs are met without degrading nature or increasing poverty, and where people have the right to participate in decisions that affect their lives.
Based in four continents, our staff has expertise in big dams, energy and water policy, climate change, and international financial institutions. We support partner organizations and dam-affected people by providing advice, training and technical assistance, and advocating on their behalf with governments, banks, companies and international agencies. The focus of our work is in Latin America, Asia and Africa.
Innovative, solutions- and service- oriented, we work across a range of areas that contribute to the progression of water management worldwide. Our programmes develop research and projects focused on solutions for water and wastewater management; we organise world-class events that bring the latest science, technology and best practice to the water sector at large; we work to place water on the global political agenda and to influence best practice in regulation and policy making; and we provide services to IWA’s global membership.

Een duurzame haven
Indonesië bestaat uit 17.508 eilanden. Voor de logistieke processen tussen deze eilandenspelen havens een belangrijke rol. Om de hoeveel vracht aan te kunnen heeft de Indonesische overheid opdracht gegeven om de eerste ‘green port’ van Indonesië in Surabaya te bouwen: Terminal Teluk Lamong. Dit is een uitbreiding van de bestaande haven. Maar wat is eigenlijk een duurzame haven en wat is mogelijk?
Mangrove herstel in combinatie met duurzame visteelt en toerisme
Een andere uitdaging in Surabaya betreft het mangrovegebied tussen de stad en de zee. Dit gebied wordt steeds kleiner, doordat de zeespiegel stijgt, het stedelijk gebied uitbreid door bevolkingsgroei en er behoefte is aan ruimte voor viskweek. De mangroves bieden veel ecosysteemdiensten, waaronder natuurlijke bescherming tegen stormvloeden, erosie, schoon water, hout, voedsel, recreatie, enzovoort. De aquacultuur is vaak de enige manier voor de lokale bevolking om in hun dagelijks levensonderhoud te voorzien. In de toekomst zijn zowel de mangroves als de aquacultuur nodig. Hoe kunnen mangroves en aquacultuur gezamenlijk op een duurzame manier ontwikkelen in combinatie met mogelijkheden voor toerisme?
Modder vulkaan
Sinds mei 2006 is in de Sidoarjo regio, ten zuiden van Surabaya de modder vulkaan Lampur Lapindo actief. Hete modderwater en gassen hebben inmiddels een gebied van 600 hectare met een laag van ca. 14 meter bedekt, 39.700 mensen raakten hun huis kwijt, 12 dorpen zijn onder de modder verdwenen, 11.241 gebouwen en 362 hectare aan rijstvelden. De gassen beïnvloeden de luchtkwaliteit en zware metalen in de modder het grondwater, en hiermee ook de landbouw en aquacultuur. Welke oplossingen zijn er om in dit gebied te leven met modder?
In het Living Lab Indonesië werken onder andere HZ en Van Hall Larenstein samen met universiteit Institut Teknologi Sepulu Napember (ITS), Instituut Teknologi Bandung, lokale bedrijven, niet-gouvernementele organisaties en overheden om deze problemen aan te pakken. Studenten van Delta Academy doen samen met Indonesische studenten praktijkgericht onderzoek in het Living Lab Water. Zij leren hiervan, maar de kennis uit het onderzoek draagt ook bij aan innovaties in deze regio, waardoor de regio meer toekomstbestendig wordt.

Makara is initiated by Christa Nooy, an Indonesia specialist with over 25 years’ experience in coordinating sustainable development projects and an extensive network of environmental organizations in Indonesia and Asia. Local communities that actively protect their natural habitats are central to her work. With Makara she develops projects with environmental organizations, knowledge institutions, governments and companies on sustainable river management. She is one of the initiators of the RVO funded aksibrantas project in East-Java and currently consultant Community Participation and NGO liaison to this project. She works through the Dutch Nedworc Foundation, a trustworthy partner that handles assignments for independent consultants and organizations operating in the international development cooperation sector.
Makara would like to introduce YUYU River Education Islands to East Java, an initiative that is developed with NorthernLight, an Amsterdam-based world renowned Dutch creative agency, and the Indonesian environmental NGO ECOTON based in Gresik, East Java. Our pledge is to build a series of floating education islands that will travel to - and work with – local communities around the world to co-create solutions to prevent plastic waste.
The first YUYU education island is designed for and with ECOTON. See the brochure (Files menu on the Portal) for an impression of this education island. The target group in this concept are schoolchildren and students, but education activities may also address the wider community. Our initial plan was to locate this island in the Brantas river, which so far has proven to be challenging because of its status as a national strategic river basin.
YUYU River Education Islands would introduce a floating education island to East Java that offers the following cultural eco systems services: esthetics, inspiration and education. YUYU’s are designed to inspire, educate and activate. Inspire with the beauty of rivers, lakes and estuaries, and the life in and around them. Educate about the plastic pollution, health and biodiversity. Activate people with a learning by doing, hands-on approach. This is why these education islands are floating on the water. People need to interact with their environment in order to adapt and learn.
The estuary where Welang river and Brantas-Porong river flow into can be suggested as a possible location for a YUYU island. The estuary with its mangroves could offer an ideal location: on one hand, the mangroves show the seriousness of the problem at a glance because they are covered in plastics (see photos in Albums). On the other hand, they have potential to become a place for place for recreation and ecotourism, and to give people a sense of belonging to nature. A YUYU education island could help maximize this potential.
The YUYU education program would be managed by ECOTON who has a network of NGOs in Welang basin. Since part of the plastics in the estuary are coming from Welang river, the education program may include an interactive campaign that travels to upstream communities. See the Brantas XOXO campaign that is now running within the aksibrantas program.
