In this document a catchment refers to a subset of the larger watershed. Watershed A topographically delineated area from which rainwater drains as surface run-off via a river or stream to a common outlet point (e.g. a large river, lake or the sea). Watershed management Securing watershed functions in a sustainable manner. Broadly these functions include: ➢ Ecological function: availability of sufficient good quality water over time, space; erosion control, soil fertility, biodiversity, clean air, carbon sequestration; ➢ Economic function: sufficient natural resource products like food, fuel wood, timber, water, fish, energy required for basic needs of the local population; income generating opportunities; ➢ Social function: maintenance of social structures; protection and development of knowledge and lifestyle arrangements; maintenance and revitalisation of cultural identity and values, recreational facilities.

The geographic scope of the Sustainable Rural Infrastructure and Watershed Management - Sector Project (SRIWSM) extends to the four provinces of Houaphan, Xieng Khouang, Louang Prabang and Xayaboury. The project will finance subprojects in three agreed districts in each province, see Table 1 and Figure 1. Table 1: Project Area Province District Houaphan 1. Nam Xeua 2. Vengxiay 3.

The ADB SRIWSM project is part of a wider investment by Government into more sustainable intensification and diversification of the agriculture sector. The investment is being supported by parallel cofinancing from IFAD (for output 1 and output 3 - WUG support) and GIZ for output 2 (with the exception of Xieng Khuoang province). ADB will invest in the establishment of irrigation headworks, conveyance systems to the command areas, and water control structures within the command areas along with the provision of improved access. IFAD will support WUGs to intensify and diversify land use during the dry season. GIZ will invest in more sustainable land uses in the upper catchments with the SRIWSM catchments prioritized. For safeguards IFAD have committed to apply ADB safeguard policy whilst GIZ is applying the required WB safeguards from the emission reduction program into which GIZ is investing. 3. Within the IEE the parallel financed activities are considered as part of associated facilities (see ADB (2012) Environmental Safeguards – A Good Practice Sourcebook. Associated facilities are those “that are not funded as part of a project but whose viability and existence depend exclusively on the Project, or where goods and services are essential for successful operation of the Project.” The guidance for these facilities or linkages (see Para 68 bullet 2) states “Even though the impacts and mitigation measures from the development of associated facilities do not have to be analysed in detail in the EIA/IEE of the project financed by ADB, basic information about the main design features, their location, the significance of potential impacts, the required 3 approval process and institutional arrangements need to be outlined in the IEE. ADBs due diligence on the levels of impacts and risks to the environment will recognize the borrower/client’s control and influence over the associated investments. 4. The implication of this on the environment of the subproject catchments is intended to have a net positive impact. This is mainly because it will reduce the risk from dry season cropping of the irrigation command areas and the potential increased income leading to both intensification and diversification. This will reduce the pressure on land conversion for upland cropping. Such land conversion is identified as a major driver of forest loss as crops are grown on steep, bare ground subject to high rates of soil erosion in the wet season. 5. The risks associated with intensification relate to (i) increased use of agrichemicals and fertilizer, and (ii) increased demand for irrigation water during the dry season. 6. For this IEE the risks linked to the “associated facilities” are the risk of intensification of agricultural inputs for the production of high value crops. The IEE incorporates the requirements to address, where necessary, risks arising from inappropriate pesticide and herbicide use through the Government Pesticide Management Training programs and where warranted IPM training within the IFAD support program. Nutrient management will be incorporated into the IFAD WUG training, farm to farm extension and on-farm demonstrations. In the situation that the timing of IFAD cofinancing is delayed the Subproject costing includes ADB financing to ensure the provisions of the EMP are covered as well as the costs of the intensification of irrigated dry season cropping. 7. Further to the impacts of the intensification that fall under the associated facilities the IEE requires that the borrower/client will not use products that fall in World Health
