  3. Withdrawals and Changes

You may freely withdraw or change your proposal at any time prior to the submission deadline by written notice to the IUCN Contact. However, in order to reduce the risk of fraud, no changes or withdrawals will be accepted after the submission deadline.

  1. EVALUATION of PROPOSALS

    1. Completeness

IUCN will firstly check your proposal for completeness. Incomplete proposals will not be considered further.

  1. Technical Evaluation
    1. Scoring Method

Your proposal will be assigned a score from 0 to 10 for each of the technical evaluation criteria, such that ‘0’ is low and ‘10’ is high.

  1. Minimum Quality Thresholds

Proposals that receive a score of ‘0’ for any of the criteria will not be considered further.

  1. Technical Score

Your score for each technical evaluation criterion will be multiplied with the respective relative weight (see Section 4.4) and these weighted scores added together to give your proposal’s overall technical score.

  1. Financial Evaluation and Financial Scores

The financial evaluation will be based upon the full total price you submit. Your financial proposal will receive a score calculated by dividing the lowest financial proposal that has passed the minimum quality thresholds (see Section 5.2.2) by the total price of your financial proposal.

Thus, for example, if your financial proposal is for a total of CHF 100 and the lowest financial proposal is CHF 80, you will receive a financial score of 80/100 = 80%

  1. Total Score

Your proposal’s total score will be calculated as the weighted sum of your technical score and your financial score.

The relative weights will be:

Technical: 70%

Financial: 30%

Thus, for example, if your technical score is 83% and your financial score is 77%, you will receive a total score of 83 * 70% + 77 * 30% = 58.1% + 23.1% = 81.2%.

Subject to the requirements in Sections 4 and 7, IUCN will award the contract to the bidder whose proposal achieves the highest total score.

  1. Explanation of procurement procedure

  1. ATTACHMENTS

Attachment 1 Specification of Requirements/Terms of Reference

ToR for a feasibility study and development of sustainable financing options for Integrated Water Resources Management in targeted arid and semi-arid counties of Kenya

  1. Scope and objectives of the consultancy

STAWI seeks the services of a consultant to undertake a feasibility study and develop a sustainable financing option for Integrated Water Resources Management in targeted arid and semi-arid counties of Kenya. The financing options will help leverage the dwindling public financing for water resources management, mainly for watershed protection measures and/or nature-based solutions that will increase water supply for domestic and productive uses.

The purpose of the consultancy is to determine the social, technical and economic feasibility of developing a sustainable financing model in multiple basins. The feasibility study will allow sustainable financing goals to be defined and economic and financial benefits from NbS activities to be clearly estimated and presented to key stakeholders.

The objectives of the consultancy are:

  1. Document any existing and/or promising initiatives to financing WRM in Kenya.
  2. Identify and analyze any bottlenecks or barriers and enablers to sustainable financing for WRM in ASAL settings.
  3. Undertake a feasibility study on the potential sustainable financing models for watershed management in ASAL settings.
  4. Based on data, evidence and/or practice in the ASAL context, propose the most viable option through criterion to be agreed upon by the stakeholders.
  5. develop a strategy for the agreed and/or preferred financing options.
  6. Highlight any necessary pre-conditions for the success of the selected models.

The basis for designing a sustainable financing model is based on understanding the contextual status of basins (ecological and socio-economic), hydrological dynamics and investment opportunities. The feasibility assessment will focus on:

  1. Quantifying the ecosystem services that are critical to primary stakeholder interests.
  2. Modelling and mapping of priority areas and interventions for NbS investments and actions in basins related to these ecosystem services.
  3. Undertaking an economic analysis to determine costs and benefits derived from NbS activities compared to “business-as-usual” scenarios to build a business case.

The feasibility assessment will benefit from among others the work of basin and sub-catchment PES schemes, water funds, water trust funds, permitting and licencing systems, and ecosystem management credits.

Potential locations include but are not limited to: one or more sub-catchments of the Tana River, one or more sub-catchments upstream of Ewaso Ng’iro and Kerio rivers, and one or more sub-catchments of the Athi and Rift Valley basins.

  1. Background

The International Union for Conservation of Nature (IUCN) is one of the subcontractors to the USAID funded STAWI – Sustainable, Transformational and Accessible Water Interventions – project that is implemented by DAI. The main goal of STAWI is to improve water security for both domestic and productive purposes in areas of recurrent crises. STAWI targets two resilience zones in Kenya, where vulnerability to recurrent crises is high. In the targeted arid counties (Turkana, Marsabit, Samburu, Isiolo, Wajir and Garissa), STAWI’s investments aim to build resilience to shocks and reduce humanitarian assistance caseloads. In the targeted semi-arid counties (Kitui, Makueni and Taita Taveta) investments aims to strengthen resilience to avert a return to dependence on humanitarian assistance. These 9 ASALs (Arid and Semi-Arid Areas) are within the following four (4) catchment areas of Kenya: Ewaso Ng’iro North, Tana, Athi and Rift Valley (see the two maps).

STAWI aims to increase the ability of counties and communities to safeguard sustainable access to adequate quantities and quality of water for sustaining livelihoods, human well-being, and socio-economic development. Improving water security therefore depends on achieving the following four interrelated objectives.

  1. Improve governance of water resources and services.
  2. Increase sustainability of water service delivery
  3. Improved management, efficiency and equitable access to water used for productive purposes.
  4. Improved collaboration and learning across stakeholders and strengthened capacity of county governments for learning and adaptation.

In support of STAWI program goals, IUCN is working with STAWI team, Water Resources Authority (WRA) and the 9 Counties in addressing water resource management, leveraging its experience in enhancing the governance of water resources and services, supporting the following: 1] development and subsequent implementation of the Basins Water Allocation Plans; 2] supporting the establishment of the multi-stakeholders platforms – the Basin Water Committees; 3] strengthening Water Resources Users Associations (WRUAs); 4] reviewing and/or supporting the development of the Sub-Catchment Management Plans (SCMPs) including implementation of priority actions those related nature-based solutions for watershed restoration; and 4] assessment of the potential financing options to leverage on public financing for integrated water resources management especially for watershed protection measures.

Water Resources Regulations, 2021 under Water Resources Authority (WRA)

The Water Resources Regulations, 2021 provides for a water conservation levy, amounting to 5 percent of the monthly water use charge. The monies collected by the Water Resources Authority (WRA) as the water conservation levy shall be segregated from the water use charges (which are used for administration purposes by WRA) and reported on separately and, on the basis of agreements entered into between the Authority and county government entities and water resource users associations and used to finance part of the costs of the implementation of catchment or sub-catchment soil and water conservation plans. This levy has not been implemented because the matter is before a Court of law.

Water Sector Trust Fund (WaterFund), 2016

Similarly, the Water Sector Trust Fund (WaterFund) established by the Water Act, 2016 is mandated to assist in financing water supply, sanitation, and water resources management projects in the underserved and marginalised rural and urban areas. The WaterFund provide conditional and unconditional grants to Counties and to assist in financing the development of and management of water services in the marginalised and underserved areas including:

  • Community level initiatives for the sustainable management of water resources,
  • Development of water services in rural areas considered not to be commercially viable for provision of water services by licensees,
  • Development of water services in the under-served poor urban areas, and
  • Promote research activities in water resource management and water services, sewerage and sanitation.

One of the challenges with this WaterFund is that it is largely supported and/or funded by the development partners hence it is not adequate and not sustainable financing mechanism.

The Green Water Credits Model

In the past, several studies have been conducted and projects undertaken to establish sustainable payment for ecosystems services (PES) in the arid lands’ watersheds. In 2007 for instance, the Green Water Credits (GWC) program designed and implemented an investment mechanism for small holder farmers, livestock keepers and pastoralists that allowed credits to smallholder farmers that promoted sustainable nature based solutions (NbS) activities in the upper Tana River. The GWC approach was further elaborated in several reports through topics that included: Hydrological Modelling, Willingness to Pay Study, Institutional Analysis, Financial Mechanisms Assessment, Carbon Capture Estimation, and Cost benefits Analysis. While the GWC model demonstrated significant potential for developing sustainable PES for watersheds, it faced limitations, including: 1) limited spatial targeting of studies; 2) low integration of diverse land use types; 3) narrow definition of a sustainable financing strategy for the PES; and 4) unclear governance and institutional structures for managing the PES schemes.

Nature-based Solution (NbS) for Water

In 2020, IUCN developed a Global Standard for NbS, outlining what constitutes an effective NbS. The IUCN Global Standard for NbS is a tool to help governments, communities, business and NGOs implement strong, effective NbS projects that are ambitious in scale and sustainable, prevent misuse and safeguard people and planet. While intervention activities can be focused on the site scale, the robustness, applicability and responsiveness of the solution should take into consideration the broader systems at play. For the case of water security, the scale is catchment or basin and/or sub-catchment levels and blending NbS with built water infrastructure. Hence NbS for water security is building on Integrated Water Resources Management (IWRM) approach.

  1. Description of the assignment

The assessment of the potential financing options will explore or identify sustainable sources of finance and a financing strategy for NbS for water and/or implementation of sub-catchment management plans (SCMPs). The consultant will develop a technical and business case that is most compelling to the context in northern Kenya. The consultant will have input on shaping the geographic scope, tasks, and outputs through contract.

Key tasks will include:

  1. Outreach to key stakeholders and stakeholder meetings.
  2. Data collection – both primary and secondary.
  3. Field visit.
  4. Preparation of feasibility plan/strategy that encompasses environmental services modeling, cost estimate for the preferred financing option.

Options could include accurately pricing water abstractions, dedicating funding from built water infrastructure projects in the area to catchment management and exploring the potential for payment for ecosystem services (PES) schemes and/or water funds. Some of the key steps or elements for developing a water fund includes:

1) identify basins, sub-basins or sub-catchments that have major water resource use for economic gain,

2) identify the various economic uses of water resources within the sub basins of interest,

3) identify the water challenges in the basin that affects the major water abstractors,

4) collect data to ascertain the challenges and status,

5) have a meeting with the abstractors and discuss strategies to address the challenges for them to pay for the ecosystem services,

6) identify water resources management activities that can be done by the WRUAs and WRA to ensure the water abstractors for economic benefits continue to receive adequate water in good qualities as the environmental flows are also considered. These activities could include increasing water storage according to water demands, increase water use efficiency activities, soil and water conservation activities, riparian zone conservation, installation of automatic river gauges for monitoring water abstraction, and addressing point source pollution,

7) conduct cost-benefit analysis for investment for a horizon of the next 10 years using RIOS model. This is to assess economic viability of the project,

8) carry out sensitivity analysis to assess the impact of specific uncertainty on the overall viability,

9) hold stakeholders’ meetings to give feedback on the predicted economic benefits of conservation activities vs financial implications for each proposed interventions for the basins e.g. the extent to which sediment reduction in the water system lowers the cost of water treatment. This is to demonstrate benefits of conservation to water users in terms of economics,

9) agree on the institutional framework for the coordination and the management of the water fund,

10) agree on the amount payable per key stakeholders and the payment modalities, and

11) implement the water fund, monitor and report its effectiveness.
