A green economy is defined as an economic model that improves human well-being and social justice while reducing environmental risks and resource constraints (unep.org.) In this context, dam construction – as green infrastructure – can provide multiple benefits (irrigation, renewable electricity, flood control, raw water, and rainwater infiltration) while posing ecological and social risks (kompas.com diklatkerja.com). This paper examines the basic and applied research plans on dams in Zumalai District, Covalima Regency, Timor-Leste, with a focus on ecological, socio-economic, and policy aspects.

1. Environmental Conditions and Water Needs in Covalima

Covalima (Timor-Leste) is a mountainous area with a pronounced rain-dry season. Local rivers (Mola, Lomea, Tafara Rivers) have the potential to be drained throughout the year. But the country is heavily dependent on rain: almost all agriculture is dependent on rain and only <10% of land is irrigated (gda.esa.int). Uneven rainfall causes flash floods during heavy rains (heavy rivers, high slopes) and severe drought in the dry season (gda.esa.int). Analysis of satellite imagery shows that the area of the water surface (e.g. Lake Lagua Seloi Kraik) has decreased dramatically in the dry season (image below), indicating a risk of drought for agriculture and the water needs of the population (gda.esa.int). This condition underscores the need for water storage solutions such as dams.

(gda.esa.int) Image: Water surface fluctuations in Lake Seloi Kraik, Timor-Leste (2018–2022). Analysis of satellite imagery shows a sharp decline in the dry season, reflecting the agricultural water crisis(gda.esa.int).

In addition to water needs, Covalima has tropical biodiversity (endemic flora) and sensitive river ecosystems. The construction of dams must consider the functions of these ecosystems, for example fishery habitats, migration of river fauna, and water quality. Global studies show dams can upset the ecological balance: deplete the diversity of migratory fish, accumulate sediment, and even release greenhouse gases (methane) from reservoirs (kompas.com diklatkerja.com). Thus, research must include ecological monitoring (fauna, flora, water quality) before and after dam construction.

2. Ecological Impact of Dams

Dams change the hydrology of rivers: part of the flow is held and released under control. The benefits include local flood control and the provision of raw water during drought (kompas.com kompas.com). However, these changes can disrupt natural river ecosystems. Retained water traps sediment (reduced sediment supply downstream) and traps nutrients, which can decrease biological production, as in the case of the Aswan Reservoir in Egypt which reduced fish yields (kompas.com). In addition, populations of migratory fish and other aquatic fauna are likely to decline due to the loss of rapid-flow habitat (pmc.ncbi.nlm.nih.gov kompas.com). A case study in Thailand, for example, reported a decline in fish numbers and diversity due to small dams (pmc.ncbi.nlm.nih.gov.)

On the contrary, with good planning, dams can increase the availability of irrigation water evenly throughout the year, supporting sustainable agriculture. Dams also provide new habitats (reservoirs) that can be used as freshwater conservation areas or natural tourism (fishing, recreation) (kompas.com.) In addition, agile dams can reduce the need for fossil fuels (due to hydropower), although it should be noted that tropical reservoirs can produce methane as a side effect (diklatkerja.com.)

Overall, this research should include ecological baseline (animal/flora inventory, water quality, fish migration patterns) and hydrological modeling. Primary data (field studies, monitoring) need to be combined with secondary data such as topographic maps, land use maps, and historical climate data. Given the current limited feasibility surveys, literature analysis and remote sensing techniques (e.g. satellite monitoring of water area and land cover) can be a starting point before intensive field surveys.

3. Socio-economic Impact and Sustainable Agriculture

The construction of the dam has a direct impact on the local community. Some of the potential socio-economic benefits include: increased agricultural productivity (guaranteed irrigation so that the land can be harvested more than once), cheaper / more equitable access to hydropower electricity, construction job opportunities and the development of new tourism and fisheries (kompas.com.) For example, Basuki Hadimuljono (Minister of PUPR RI) said that dams support food security, irrigation, energy, and tourist destinations that increase residents' income (kompas.com.) By collecting surface water in reservoirs, farmers can plant more during droughts, and villages get a constant supply of renewable electricity (diklatkerja.com kompas.com.)

However, the negative socio-economic impact is also real. Residents can lose land or houses due to reservoir inundation; Land conflicts often occur in land clearances for dams (kompas.com.) In the example in Indonesia, the rejection of the residents of Wadas (Central Java) regarding the land for the Bener Dam caused tension (diklatkerja.com.) In addition, the benefits of dams are often "uneven": a study in Thailand found that upstream villages get additional irrigation water and increased income, while downstream villages are water deficient and their income is stagnant (pmc.ncbi.nlm.nih.gov.) This difference arises because downstream communities depend on natural runoff water that is reduced by upstream dams (pmc.ncbi.nlm.nih.gov.) Therefore, water distribution equity (sharing) and community participation are very important in this research (pmc.ncbi.nlm.nih.gov.)

(pmc.ncbi.nlm.nih.gov) Image: Dam studies in Thailand show upstream villages benefit from better irrigation, while downstream villages are less satisfied with pmc.ncbi.nlm.nih.gov water flow.

For the Zumalai-Covalima community, the research needs to examine: livelihood patterns (rice/field farming, river fish), social structure (customs, land ownership), and residents' perceptions of dam construction. In-depth surveys and interviews should be conducted before and after construction to assess changes in people's lives. Participatory approaches can increase community ownership of projects and conflict mitigation (pmc.ncbi.nlm.nih.gov kompas.com.)

4. Policies, Regulations and Recommendations

Dams are not just technical projects; they are inherent in the national water resources and sustainability policy framework. This research should include policy studies: e.g. environmental impact assessments (EIAs), irrigation and water sharing regulations, and hydropower regulations in Timor-Leste. Dam observer Didiek Djarwadi emphasized the importance of careful location determination through multidisciplinary studies (kompas.com.) Similarly, in this research it is necessary to discuss how the choice of location (Mola, Lomea, or Tafara rivers) will affect the function and benefits of dams in Covalima.

One of the important findings of the study in Thailand was the need for an Environmental and Social Impact Assessment (ESIA) even for small dams, as well as clear rules on water allocation (pmc.ncbi.nlm.nih.gov pmc.ncbi.nlm.nih.gov.) Research in Covalima should map out the need for such regulation, including identifying local institutions/canals (such as customary irrigation traditions) that can be integrated. Timor-Leste's national policies (e.g. Climate Adaptation Plan and National Development Strategy) need to be reviewed to ensure dam projects support food security and environmental management (gda.esa.int pmc.ncbi.nlm.nih.gov.) goals. If necessary, recommend the establishment of collaborative rules (water-sharing agreements) between upstream-downstream villages and between local governments.

5. Recommended Research Methodology

The research approach must be multidisciplinary and a combination of basic research (literature analysis, hydro-economic models, theoretical studies) with applied research (field surveys, socio-ecological experiments). Here are the main steps proposed:

Literature and Secondary Data Review: Collect preliminary data from tertiary sources such as the list of Indonesian dams (id.wikipedia.org), Timor-Leste hydrogeological publications, satellite imagery (DEM/topography), water level monitoring (gda.esa.int), and Covalima socio-economic statistics. Analyze historical climate data and rainfall patterns to model river discharge and optimal reservoir capacity.
Hydrological and Ecological Survey: Conduct field measurements (river flow, water quality, sediment thickness) at all three potential dam locations. Inventory of fish resources and downstream stream fauna to assess potential habitat conflicts. Use scenario hydrological models (weir vs no dam) to project seasonal flow changes.
Social-participatory Approach: Hold Focus Group Discussions (FGDs) and semi-structured interviews with farming communities and indigenous leaders in villages along the Mola, Lomea, and Tapara Rivers. Learn about traditional irrigation systems, community dependence on agricultural land, and the perception of the risks and benefits of dams. Identify local authorities (villages/sub-districts) and stakeholder interests (including cross-border if relevant).
Economic and Policy Analysis: Assess the economic benefits of dams (nPV, B/C) by including irrigation and energy added value, as well as environmental-social costs (e.g. land loss, fish decline). Review national and international regulations (e.g. Sustainable Development Standards, Timor-Leste's climate adaptation policy) to develop contextual policy recommendations.
Green Economy Synthesis: Combine the above ecological-social data into a green economy framework—ensuring that the principles of sustainability, social inclusion, and resource efficiency are met (unep.org.) For example, consider compensation mechanisms or incentives (pay-services-ecosystem) for downstream communities if they bear part of the costs (e.g. flood functions), as well as new "green economy" opportunities (agrotourism, marine and aquaculture in reservoirs).

With the above method, this research will comprehensively reveal the positive and negative impacts of dams on ecosystems, farmers, and local policies. Critical questions (how is water distributed? how is ecological loss mitigated?) should be the focus. The overall research must uphold citizen participation and local literacy, in accordance with the demands of inclusive and sustainable green economy development (unep.org pmc.ncbi.nlm.nih.gov.)

6. Conclusion

Dam research in Covalima (Zumalai) is needed to assess in depth the potential green economic benefits (resilient irrigation water, clean energy, tourism) and ecological-social impacts (habitat destruction, land conflicts, water distribution) of dam construction. With an interdisciplinary and participatory approach, this research will provide the basis for wise decision-making: maximizing food and energy security while minimizing environmental and social risks. Among them, comparative studies with dam projects in similar regions (e.g. Indonesia) can enrich the analysis. Up-to-date references and data should be prioritized, such as id.wikipedia.org national dam inventories and monitoring of water level changes based on gda.esa.int satellite imagery, to ensure evidence-based dam construction decisions and support sustainable development goals.

Ekonomi Hijau dan Bendungan untuk Pembangunan Berkelanjutan di Covalima

Ekonomi hijau didefinisikan sebagai model ekonomi yang meningkatkan kesejahteraan manusia dan keadilan sosial sambil mengurangi risiko lingkungan dan keterbatasan sumber daya (unep.org.) Dalam konteks ini, pembangunan bendungan – sebagai infrastruktur hijau – dapat memberikan manfaat berganda (irigasi, listrik terbarukan, pengendali banjir, air baku, dan resapan air hujan) sekaligus menimbulkan risiko ekologis dan sosial (kompas.com diklatkerja.com). Risalah ini mengkaji rencana penelitian dasar dan terapan tentang bendungan di Kecamatan Zumalai, Kabupaten Covalima (Timor-Leste), dengan fokus pada aspek ekologi, sosial-ekonomi, dan kebijakan.

1. Kondisi Lingkungan dan Kebutuhan Air di Covalima

Covalima (Timor-Leste) merupakan daerah bergunung dengan musim hujan-kemarau yang jelas. Sungai-sungai setempat (Sungai Mola, Lomea, Tafara) berpotensi dialiri sepanjang tahun. Namun negara ini mengalami ketergantungan kuat pada hujan: hampir seluruh pertanian bergantung pada hujan dan hanya <10% lahan teraliri irigasi (gda.esa.int). Curah hujan yang tidak merata menyebabkan banjir bandang saat hujan lebat (sungai deras, kemiringan tinggi) dan kekeringan parah di musim kemarau (gda.esa.int). Analisis citra satelit menunjukkan luas permukaan air (misalnya Danau Lagua Seloi Kraik) mengalami penurunan dramatis pada musim kemarau (gambar di bawah), menandakan risiko kekeringan bagi pertanian dan kebutuhan air penduduk (gda.esa.int). Kondisi ini menggarisbawahi perlunya solusi penampungan air seperti bendungan.

(gda.esa.int) Gambar: Fluktuasi permukaan air di Danau Lagua Seloi Kraik, Timor-Leste (2018–2022). Analisis citra satelit menunjukkan penurunan tajam musim kering, mencerminkan krisis air pertanian(gda.esa.int).

Selain kebutuhan air, Covalima memiliki keanekaragaman hayati tropis (flora-fauna endemik) dan ekosistem sungai yang sensitif. Pembangunan bendungan harus mempertimbangkan fungsi ekosistem ini, misalnya habitat perikanan, migrasi fauna sungai, dan kualitas air. Studi global menunjukkan bendungan dapat mengganggu keseimbangan ekologis: menurunkan keanekaragaman ikan migran, mengakumulasi sedimen, dan bahkan melepaskan gas rumah kaca (metana) dari waduk (kompas.com diklatkerja.com). Dengan demikian, penelitian riset harus meliputi pemantauan ekologi (fauna, flora, kualitas air) sebelum dan sesudah konstruksi bendungan.

2. Dampak Ekologis Bendungan

Bendungan mengubah hidrologi sungai: sebagian aliran ditahan dan dilepaskan terkontrol. Manfaatnya antara lain pengendalian banjir lokal dan penyediaan air baku saat kemarau (kompas.com kompas.com). Namun perubahan ini dapat mengganggu ekosistem sungai alami. Air yang tertahan akan memerangkap sedimen (berkurangnya pasokan sedimen ke hilir) dan memerangkap nutrisi, yang dapat menurunkan produksi biologi, seperti pada kasus Waduk Aswan di Mesir yang mengurangi hasil ikan (kompas.com). Selain itu, populasi ikan migran dan fauna akuatik lainnya kemungkinan menurun karena hilangnya habitat aliran deras (pmc.ncbi.nlm.nih.gov kompas.com). Studi kasus di Thailand misalnya, melaporkan penurunan jumlah dan keragaman ikan akibat bendungan kecil (pmc.ncbi.nlm.nih.gov.)

Sebaliknya, dengan perencanaan baik bendungan bisa meningkatkan ketersediaan air irigasi secara merata sepanjang tahun, mendukung pertanian berkelanjutan. Bendungan juga menyediakan habitat baru (waduk) yang bisa dimanfaatkan sebagai daerah konservasi air tawar atau wisata alam (pemancingan, rekreasi) (kompas.com.) Selain itu, bendungan tangkas dapat mengurangi kebutuhan pembangkit fosil (karena PLTA), walau perlu dicermati bahwa waduk tropis dapat menghasilkan metana sebagai efek samping (diklatkerja.com.)

Secara keseluruhan, penelitian ini harus meliputi baseline ekologi (inventarisasi satwa/flora, kualitas air, pola migrasi ikan) dan pemodelan hidrologi. Data primer (studi lapangan, monitoring) perlu digabung dengan data sekunder seperti peta topografi, peta penggunaan lahan, dan data iklim historis. Dengan terbatasnya survei kelayakan saat ini, analisis literatur dan teknik pengindraan jauh (misalnya pemantauan satelit luasan air dan tutupan lahan) bisa menjadi pijakan awal sebelum survei lapangan intensif.

3. Dampak Sosial-ekonomi dan Pertanian Berkelanjutan

Konstruksi bendungan berdampak langsung pada masyarakat lokal. Beberapa manfaat sosial-ekonomi yang potensial antara lain: peningkatan produktivitas pertanian (irigasi terjamin sehingga lahan bisa lebih dari sekali panen), akses listrik PLTA yang lebih murah/merata, kesempatan kerja konstruksi serta pengembangan wisata dan perikanan baru (kompas.com.) Misalnya, Basuki Hadimuljono (Menteri PUPR RI) menyebut bendungan mendukung ketahanan pangan, irigasi, energi, dan destinasi wisata yang meningkatkan pendapatan warga (kompas.com.) Dengan mengumpulkan air permukaan dalam waduk, petani bisa menanam lebih banyak selama kemarau, dan desa mendapatkan pasokan listrik terbarukan yang konstan (diklatkerja.com kompas.com.)

Namun dampak negatif sosial-ekonomi juga nyata. Warga dapat kehilangan lahan atau rumah akibat genangan waduk; konflik lahan sering terjadi dalam pembebasan tanah untuk bendungan (kompas.com.) Pada contoh di Indonesia, penolakan warga Wadas (Jawa Tengah) terkait lahan untuk Bendungan Bener menimbulkan ketegangan (diklatkerja.com.) Selain itu, manfaat bendungan sering “tidak merata”: studi di Thailand menemukan desa hulu mendapatkan air irigasi tambahan dan peningkatan pendapatan, sedangkan desa hilir justru kekurangan air dan pendapatan mereka stagnan (pmc.ncbi.nlm.nih.gov.) Perbedaan ini muncul karena masyarakat hilir bergantung pada air limpasan alami yang berkurang oleh bendungan hulu (pmc.ncbi.nlm.nih.gov.) Oleh karena itu, keadilan distribusi air (sharing) dan partisipasi komunitas sangat penting dalam riset ini (pmc.ncbi.nlm.nih.gov.)

(pmc.ncbi.nlm.nih.gov) Gambar: Studi bendungan di Thailand menunjukkan desa hulu mendapat manfaat irigasi lebih baik, sementara desa hilir kurang puas dengan aliran airpmc.ncbi.nlm.nih.gov.

Untuk masyarakat Zumalai-Covalima, riset perlu mengkaji: pola mata pencaharian (pertanian padi/ladang, ikan sungai), struktur sosial (adat, kepemilikan tanah), dan persepsi warga tentang pembangunan bendungan. Survei dan wawancara mendalam harus dilakukan sebelum dan sesudah pembangunan untuk menilai perubahan kehidupan masyarakat. Pendekatan partisipatif dapat meningkatkan kepemilikan komunitas terhadap proyek dan mitigasi konflik (pmc.ncbi.nlm.nih.gov kompas.com.)

4. Kebijakan, Regulasi, dan Rekomendasi

Bendungan bukan sekadar proyek teknis; ia melekat pada kerangka kebijakan sumber daya air dan keberlanjutan nasional. Penelitian ini harus menyertakan kajian kebijakan: misalnya kajian dampak lingkungan (AMDAL/EIA), regulasi irigasi dan pembagian air, serta peraturan PLTA di Timor-Leste. Pengamat bendungan Didiek Djarwadi menekankan pentingnya penentuan lokasi yang matang melalui studi multidisiplin (kompas.com.) Demikian pula dalam riset ini perlu dibahas bagaimana pemilihan lokasi (sungai Mola, Lomea, atau Tafara) akan memengaruhi fungsi dan manfaat bendungan di Covalima.

Salah satu temuan penting studi di Thailand adalah perlunya Environmental and Social Impact Assessment (ESIA) walau untuk bendungan kecil, serta aturan jelas tentang pembagian air (pmc.ncbi.nlm.nih.gov pmc.ncbi.nlm.nih.gov.) Riset di Covalima harus memetakan kebutuhan regulasi semacam itu, termasuk mengidentifikasi institusi lokal/kanal (seperti tradisi adat pengairan) yang bisa diintegrasikan. Kebijakan nasional Timor-Leste (misalnya Rencana Adaptasi Iklim dan Strategi Pembangunan Nasional) perlu dikaji untuk memastikan proyek bendungan mendukung tujuan ketahanan pangan dan pengelolaan lingkungan (gda.esa.int pmc.ncbi.nlm.nih.gov.) Jika perlu, rekomendasikan pembentukan aturan kolaboratif (water-sharing agreements) antara desa hulu-hilir dan antara pemerintah daerah setempat.

5. Metodologi Riset yang Disarankan

Pendekatan penelitian harus multidisiplin dan kombinasi riset dasar (analisis literatur, model hidro-ekonomi, kajian teoretis) dengan riset terapan (survei lapangan, eksperimen sosial-ekologi). Berikut langkah-langkah utama yang diusulkan:

Kajian Literatur dan Data Sekunder: Kumpulkan data awal dari sumber tersier seperti daftar bendungan Indonesia (id.wikipedia.org), publikasi hidrogeologi Timor-Leste, citra satelit (DEM/topografi, pemantauan permukaan air (gda.esa.int), dan statistik sosial-ekonomi Covalima. Analisis data iklim historis dan pola curah hujan untuk memodelkan debit sungai dan kapasitas waduk optimal.
Survei Hidrologi dan Ekologi: Lakukan pengukuran lapangan (aliran sungai, kualitas air, ketebalan sedimen) di ketiga lokasi calon bendungan. Inventarisasi sumber daya ikan dan fauna hilir-hulu untuk menilai potensi konflik habitat. Gunakan model hidrologi skenario (bendung vs tanpa bendung) untuk memproyeksikan perubahan aliran musiman.
Pendekatan Sosial-partisipatif: Gelar Focus Group Discussion (FGD) dan wawancara semi-terstruktur dengan masyarakat petani dan pemimpin adat di desa sepanjang Sungai Mola, Lomea, dan Tafara. Pelajari sistem irigasi tradisional, ketergantungan masyarakat pada lahan pertanian, serta persepsi risiko-manfaat bendungan. Identifikasi kewenangan lokal (desa/camat) dan kepentingan pemangku kepentingan (termasuk lintas batas jika relevan).
Analisis Ekonomi dan Kebijakan: Kaji manfaat ekonomi bendungan (nPV, B/C) dengan memasukkan nilai tambah irigasi dan energi, serta biaya lingkungan-sosial (mis. kehilangan lahan, penurunan ikan). Tinjau regulasi nasional dan internasional (mis. Standar Pembangunan Berkelanjutan, kebijakan adaptasi iklim Timor-Leste) untuk menyusun rekomendasi kebijakan yang kontekstual.
Sintesis Green Economy: Gabungkan data ekonomi-ekologi-sosial di atas ke dalam kerangka ekonomi hijau—memastikan bahwa prinsip keberlanjutan, inklusi sosial, dan efisiensi sumber daya terpenuhi (unep.org.) Misalnya, pertimbangkan mekanisme kompensasi atau insentif (bayar-jasa-ekosistem) bagi masyarakat hilir jika mereka menanggung sebagian biaya (mis. fungsi banjir), serta peluang “ekonomi hijau” baru (agrowisata, kelautan dan perikanan budidaya di waduk).

Dengan metode di atas, riset ini akan mengungkap secara komprehensif dampak positif dan negatif bendungan terhadap ekosistem, petani, dan kebijakan lokal. Pertanyaan-pertanyaan kritis (bagaimana pembagian air? bagaimana mitigasi kerugian ekologi?) harus menjadi fokus. Keseluruhan penelitian harus menjunjung partisipasi warga dan literasi lokal, sesuai tuntutan pengembangan green economy yang inklusif dan berkelanjutan (unep.org pmc.ncbi.nlm.nih.gov.)

6. Kesimpulan

Riset bendungan di Covalima (Zumalai) diperlukan untuk menilai secara mendalam potensi manfaat ekonomi hijau (air irigasi tahan banting, energi bersih, wisata) dan dampak ekologis-sosial (kerusakan habitat, konflik lahan, distribusi air) dari pembangunan bendungan. Dengan pendekatan interdisiplin dan partisipatif, penelitian ini akan memberikan dasar bagi pengambilan keputusan yang bijak: memaksimalkan ketahanan pangan dan energi sambil meminimalkan risiko lingkungan dan sosial. Di antaranya, studi banding dengan proyek bendungan di wilayah serupa (misal Indonesia) dapat memperkaya analisis. Referensi dan data terkini harus diutamakan, seperti inventaris bendungan nasional id.wikipedia.org dan pemantauan perubahan permukaan air berbasis citra satelit gda.esa.int, guna memastikan keputusan pembangunan bendungan berbasis bukti dan mendukung tujuan pembangunan berkelanjutan.
