Abstract
Keywords:
1. Introduction
2. A look at the Chota Valley
3. Poverty and Climate Change
Poverty
- The dwelling has inadequate physical characteristics
- The house has inadequate services
- The household has high economic dependence
- In the home there are children who do not attend school
- The household is critically overcrowded
Climate Change and Poverty
“…changes in agricultural production models, derived from climate change, will affect food security in two ways. First, the food supply locally and globally will be affected. In many low-income countries, with limited financial capacity to trade and relying largely on their own production to meet their food needs, it may be impossible to make up for the decline in local supply without increasing their reliance on food aid. Second, all traditional forms of agricultural production will be affected and the ability to access food will be reduced.
It is important to mention that in addition to agricultural production, other processes of the food system are equally important with respect to food security and poverty, such as the processing, distribution, acquisition, preparation and consumption of food. With climate change, the risk of damage to transport by storms and distribution infrastructure increases with the consequent disorganization in food production chains. In addition to the above, current projections for 2030 show that the share of groceries in the average expenditure of a family will continue to increase, due, among other factors, to the growing scarcity of water, land and fuel that exert progressive pressure on food prices generating higher levels of poverty”.
- Methodology
- Quantitative Approach:
3.1. Relationship Between Poverty and Climatic Variables
- Household (agricultural) income per capita i
- Average temperature in the home location i
- Monthly average precipitation per quarter (taking the central month as a proxy for the quarter, that is, February, May, August, November)
- Home features vector i
- error term
3.2. Relationship Between Poverty, Knowledge About Climate Change, Actions and Adaptation to Climate Change
- is a binary dependent variable (with two possible values, 0 and 1).
- are a set of k independent variables, observed in order to predict or explain the value of .
- Y Knowledge about climate change
- Vector of independent variables, including the PMT variable
- Probability of knowing about climate change explained by the PMT poverty rate and household characteristics variables
- Regression coefficients (Parameters to be estimated)
Qualitative approach

- Sample qualitative part: Initially, the development of 2 focus groups of 10 people (Adults and youth represented equally by gender, authorities, leaders and local leaders, for each of the communities) is planned. Fewer or more focus groups may be held depending on the achievement of “component saturation”.
Appendix A.3. Guide to Questions
- Core Question
- How has climate change affected the poverty conditions of the population of Chota Valley, during the period 2014-2017?
- We are going to ask you to answer some questions about it:
- Big Topics:
- 1.
- Brief presentation of the topic and rules
- 2.
- Presentation of the participants

-
Climate change knowledge
- 1-
- Have you heard or know about what climate change is?
- 2-
- From 2014 to now, have you seen changes in the local climate (I mean changes in rainfall, dry weather, hotter, colder)?
- 3-
- Regarding plants, have you seen or heard of the disappearance of some wild plants and the appearance of others?
- 4.
-
Opinion on changes in production
- 4-
- An indicator of climate change is said to be the presence or absence of bees. From your memories have you seen more bees before (2014) than now?
- 5-
- From 2014 to now, have you seen changes in the production of mangoes (I mean improvements, damage to the plants, have they had to apply more fungicides, do they no longer produce the same amount?
- 6-
- From 2014 to now, have you seen changes in the production of ovos (I mean improvements, damage to the plants, have they had to apply more fungicides, do they no longer produce the same amount?

- 5.
-
Opinion on water sources and irrigation
- 9-
- The sources of water for irrigation between 2014 and now remain the same (I mean that they all exist, their flow has been reduced, there were springs)
- 10-
- Regarding irrigation for the production of mangoes, if we compare between 2014 and now. Today it needs more irrigation, less irrigation or the same.

- 15-
- What is the main factor that has influenced the change in your standard of living?
- 16-
- Do you think that the change in your standard of living has to do with changes in climatic conditions (due to the change in production, in your health, etc...)
