Thailand, 27-28 November 2017 - UNDP and GIZ partnered with the Thailand Office of Agriculture Economics (OAE) to launch a workshop designed to connect vital stakeholders to build an effective National Adaptation Plan.
The two-day workshop at the Rama Garden Hotel had 20 participants from each department under the Ministry of Agriculture and Cooperatives (MOAC). The workshop was designed to build capacity of planning officers to formulate better projects and budget submissions as well as potential climate finance proposal using cost-benefit analysis and ecosystem-based analysis appraisal tools.

Context
The Government of Thailand intends to request financial
support from the Green Climate Fund (GCF) to fund an
investment project in north central Thailand.
Proposals submitted to GCF MUST contain an economic
analysis – and sometimes also a financial analysis.
In a GCF proposal:
Section E.6: Efficiency and Effectiveness (discuss economic and, if
appropriate, financial soundness of the project).
Section F.1: Economic and Financial Analysis.
Annex XII: Economic Analysis (detailed economic analysis plus
Excel spreadsheet with economic analysis).
8. 8
Project description
Problem:
Climate projections: A significantly greater frequency and intensity of
flooding during wet season, and extended drought periods during the
dry season, presenting a significant challenge to effective water
management in Thailand.
9. 9
Project description
Problem:
Flood and drought events have become more severe, causing losses
and damages to crop production and farmers’ income.
Higher levels of poverty for the Northern-Central region in turn, means
that this area also has an increased level of vulnerability to climate
change impacts, with lower levels of access to resources for
adaptation strategies and in which to build climate resilience.
Calculations for the region, found that on average (with variations
between the provinces) during 2040 -2049, farmland values per rai, are
projected to decrease from $2,703 to $2,068 and $2,538 per rai in
climate scenarios A2 and B2 respectively.
10. 10
Project description
Overall purpose of proposed project
The objective of the proposed GCF project is to adapt water management
and use in the Yom and Nan river basins to changing climatic conditions.
4 components
• Improved climate and risk informed planning in the water and
agricultural sectors.
• Strengthened water management infrastructure for greater resilience
to projected climate change.
• Increased resilience of agriculture livelihoods in drought and flood
prone areas.
• Project management

Are we done with the costs component of the CBA?
How about the operation and maintenance costs?
18. 18
How about the operation and maintenance costs?
We read in the proposal: “Once the totality of assets is in
place, annual operation and maintenance (O&M) costs
have been estimated to be $1,120,000.”
What to do with this information?
Easiest approach would be: Investment is taking place
from 2018 to 2022. For those years, we will put ZERO
(O&M), and then we will enter $1,120,000 in 2023.
Another approach?

Estimated costs
We have the annual breakdown of the capital cost:
Total 2018 2019 2020 2021 2022

This implies the following disbursement schedule (% of
disbursement):
2018 2019 2020 2021 2022 2023
14.3 20.5 25.7 24.7 14.8
14.3 34.9 60.5 85.2 100.0

Estimating economic benefits to agriculture
Please discuss methodological framework you would use to
estimate the potential economic benefits of the proposed
investment project on agriculture.
25. 25
Agriculture benefits
Methodological approach:
1. Determine the number of rais (area) benefiting from the project
investment.
2. Assess the potential impacts of climate change on productivity
without project (scenario with climate change, without project).
3. Assess the potential impacts of the project on productivity (scenario
with climate change, with project).
The difference between the “yield with project” and “yield without
project” will be the benefits of the project measured in physical terms
(incremental quantity of agricultural output).
4. Compute the net economic returns of the incremental agricultural
output allowed by the project.

Potential impacts of CC without project
What is next question to ask?
What could happen to these yields in the future without the project?
Go to literature.
Then what do we do?
Given the above uncertainty, the economic analysis assumes a
reduction of 5%, 10%, and 15% and 20% by 2042.
31. 31
Agriculture benefits
Projected agriculture yield with project
Activities of a similar nature have been recently implemented in
Thailand. Under such circumstances, yields have been shown to
reach between 750 and 1,000 kg per rai. For purpose of this economic
analysis, the lower bound value of 750 kg per rai is used in the
analysis.
How to answer this?
Now we can calculate how many more kg of rice we may get as a
result of the project.
