Adaptations and mitigation: Questions and answers part 5

Q: Is there a climate change programme in your country? Please summarize steps in developing, and contents.

Ans: National Action Plan on Climate Change (NAPCC)

This action plan outlines a number of steps to simultaneously advance India's development and climate change-related objectives. The National Action Plan on Climate Change (NAPCC) encompasses a range of measures. It focuses on eight missions, which are as follows:

  1. National Solar Mission: The NAPCC aims to promote the development and use of solar energy for power generation and other uses, with the ultimate objective of making solar competitive with fossil-based energy options. It also includes the establishment of a solar research center, increased international collaboration on technology development, strengthening of domestic manufacturing capacity, and increased government funding and international support.

  2. National Mission for Enhanced Energy Efficiency: The NAPCC recommends mandating specific energy consumption decreases in large energy-consuming industries, with a system for companies to trade energy-saving certificates, financing for public–private partnerships to reduce energy consumption through demand-side management programs in the municipal, buildings, and agricultural sectors, and energy incentives, including reduced taxes on energy-efficient appliances.

  3. National Mission on Sustainable Habitat: The NAPCC also aims at promoting energy efficiency as a core component of urban planning by extending the existing Energy Conservation Building Code, strengthening the enforcement of automotive fuel economy standards, and using pricing measures to encourage the purchase of efficient vehicles and incentives for the use of public transportation. The NAPCC also emphasizes on waste management and recycling.

  4. National Water Mission: The NAPCC sets a goal of a 20% improvement in water use efficiency through pricing and other measures to deal with water scarcity as a result of climate change.

  5. National Mission for Sustaining the Himalayan Ecosystem: This particular mission sets the goal to prevent melting of the Himalayan glaciers and to protect biodiversity in the Himalayan region.

  6. Green India Mission: The NAPCC also aims at afforestation of 6 million hectares of degraded forest lands and expanding forest cover from 23 to 33% of India's territory.

  7. National Mission for Sustainable Agriculture: The NAPCC aims to support climate adaptation in agriculture through the development of climate-resilient crops, expansion of weather insurance mechanisms, and agricultural practices.

  8. National Mission on Strategic Knowledge for Climate Change: To gain a better understanding of climate science, impacts, and challenges, the plan envisions a new Climate Science Research Fund, improved climate modeling, and increased international collaboration. It also encourages private sector initiatives to develop adaptation and mitigation technologies through venture capital funds.

The NAPCC also describes other ongoing initiatives that are as follows:

  1. Power generation: The government is mandating the retirement of inefficient coal-fired power plants and supporting the research and development of Integrated Gasification Combined Cycle IGCC and supercritical technologies.

  2. Renewable energy: Under the Electricity Act 2003 and the National Tariff Policy 2006, the central and the state electricity regulatory commissions must purchase a certain percentage of grid-based power from renewable sources.

  3. Energy efficiency: Under the Energy Conservation Act 2001, large energy-consuming industries are required to undertake energy audits and an energy-labeling program for appliances has been introduced.

  4. Proposals for health sector: The proposed program comprises two main components, namely provision of enhanced public health care services and assessment of increased burden of diseases due to climate change.

  5. Implementation: Ministries with lead responsibility for each of the missions are directed to develop objectives, implementation strategies, timelines, and monitoring and evaluation criteria to be submitted to the Prime Minister's Council on Climate Change. The Council will also be responsible for periodically reviewing and reporting on each mission's progress. To be able to quantify progress, appropriate indicators and methodologies will be developed to assess both avoided emissions and adaptation benefits.

Q: How to prepare climate and climate information in a simple way to provide to the end-user.

Ans : The severity of climate change impacts to develop strategies that modify or prevent these impacts. Hence, robust climate change impact assessment studies are needed, to assess the vulnerability of given systems and to develop reliable adaptation strategies. For each of these climate change impact assessment studies, climate data are either directly interpreted or used in impact models by end-users. End-users are often unsure about the data access, quality of data, and correct usage of data. end-users need information on local or regional scale.

Hence, downscaling techniques have to be accomplished that not only bridge the spatial resolution gap between GCM and local information in a sound way, but are also suitable for the purpose intended by the end-user (e.g. heavy rain or summer temperature analyses). End users require precisely tailored downscaling products with detailed guidelines on their interpretation and limitations.

Consequently, there is a need to improve the communication between the downscaling community and stakeholders, with a more targeted exchange of information about what is needed from the end user, and what can and cannot be provided by downscaling methods.

Climate Change: questions and answers part 3

 Ques: We would appreciate if you can suggest any potential questions for this purpose. Can you say whether the climate change has similar or variable impact on food production at varying latitude? If so, explain the reason for the similar or variable impact?

Ans: Yes, The climate change have a variable impact on food production at varying latitude because change in latitude changes the climate which may be either tropical and temperate and also the belt of vegetation which primarily depends upon climatic conditions. It can be seen that in the tropical climate, higher temperature will create more atmospheric water demand leading to water stress. The developing countries are located in tropical climate which have fewer resources with low adaptive capacity to the changing agricultural production because of climate change. So, it is not necessary that climate will have similar impact on variation of latitude, it will always be variable in nature.


Ques: What are the properties of crop model for its application in climate change impact analysis?
Ans: The properties of crop model for its application in climate change impact analysis:

1) Basic growth processes

2) Phenological development

3) Biomass accumulation

4) Growth and yield

5) Soil water balance

6) Soil carbon and nitrogen balance

Use soil-crop models system (DSSAT, APSIM, Expert-N, InfoCrop) for:

a) evaluation of adaptation options:

– Weather uncertainty

–Input uncertainty (Price and management)


b) evaluation of climate change mitigation:

– Water and nutrient management to reduce greenhouse gas emission

– Organic farming for carbon sequestration


Q: Often precipitation and temperature are the most commonly required parameters used for impact studies. Give some examples of impact study procedures (ex. flood) and the parameters that you would use from climate projections.

Ans: After downscaling either by statistical or dynamical method following procedure are adopted:

A) Qualitative Description

B) Indicators of change

C) Compliance to standards

D) Cost and benefit

E) Geographical analysis

F) Dealing  with uncertainty

 The parameters that would be used from climate projections are:

Precipitation, Temperature, CO2, Land use, Pollution, Water resources, agriculture.

Q: Describe the type of downscaling approach you would use for (a) a flood study and (b) a rice yield change study. Give reasons for your choice

Ans: For flood study dynamic scaling method would be used because,it is based upon assumptions and resolutions and if forced with with observations it can simulate real natural events which is not possible in case of statistical scaling approach.

While, for rice yield statistical scaling method would be used because, it is based upon generation of synthetic series of data at a local variable site between local scale predict and large scale predictors, as results are limited to local climatic conditions and enormous amount of previous year data is needed to compute the analysis.

Q:  What is the difference between climate change adaptation and climate change mitigation?

Ans: Adaptation and mitigation are complementary to each other. For example, if mitigation measures are undertaken effectively, lesser will be the impacts to which we will need to adapt. Similarly, if adaptation measures are strong, lesser might be the impacts associated with any given degree of climate change.
There are some differences between adaptation and mitigation, but if the key vulnerabilities to climate change are to be addressed, adaptation is essential as even after the most rigorous mitigation efforts, climate change will continue in the next few decades. At the same time, mitigation is necessary because reliance on adaptation alone could eventually lead to a magnitude of climate change to which effective adaptation is possible only at very high social, environmental, and economic costs.
