CPI receives MapBiomas team for workshop on land mapping and use in Brazil

August 17, 2017 |


MapBiomas workshop in CPI in Rio de Janeiro

Project aims at helping researchers with a fast and detailed system

Climate Policy Initiative (CPI) hosted the Brazilian Annual Land Use and Land Cover Mapping Project (MapBiomas) team for a workshop to present the platform and explain how it operates. The event, held in early August at CPI’s office in Rio de Janeiro, gathered researchers, analysts and university faculty from CPI and other institutions including IBGE, FIOCRUZ, BVRio, and UFRJ.

MapBiomas is an initiative that involves a collaborative network of biomes, land use, remote sensing, GIS (Geographic Information System) and computer science experts. It relies on Google Earth Engine platform and its cloud processing and automated classifiers capabilities to map and present dynamics of land use changes in agriculture, farming, forests and urban areas, among others.

In Brazil, CPI works to support policymakers to implement the most effective policies for protecting Brazil’s natural resources while also advancing the nation’s agricultural production.

For CPI executive director Juliano Assunção, MapBiomas greatly expands the volume of information for land use analysis in Brazil and provides an example for other initiatives involving collaborative work. Assunção believes that the project enhance CPI’s research. “CPI focuses its efforts on generating evidence on the effectiveness of policies and their various impacts on Brazilian society. With MapBiomas, we can now investigate dynamics of land use conversion inside and outside the Amazon biome with much more precision,” he says.


Land use and land cover maps, satellite images mosaics, and a public web platform are among the MapBiomas products. According to the coordinator of the project Tasso Azevedo, the platform aims to provide analysts and researchers with the tools needed to analyze data and build on. “We wanted to replace the simple matrix “forest and non-forest” with a more nuanced one. The challenge is and has always been to map in a cheap, fast and historical way”, he says. One of the unique characteristics of MapBiomas is that it classifies using temporal and spatial filters, which can be applied to a more detailed analysis.

MapBiomas provides a series of scientific analyses for the improvement of policies. According to Assunção, besides putting together detailed information on territories, MapBiomas presents the data in an intuitive and comprehensible way. “Although the actual data are not precise for calculating deforestation rates, for example, its potential is huge. For example, important topics such as infrastructure can be studied in depth,” the CPI director says.

Currently, only Brazil develops a mapping of tropical countries and their lands. Nevertheless, it is expected that over the next two years a project like MapBiomas might become a potential investment for other countries. The development of MapBiomas is constant and an updated version, with adjustments in the filters, will be launched soon.

Changing land use patterns in Brazil

October 29, 2015 | and


As the demand for food and climate change risk both increase, a new study explores paths to more efficient land use in the country.

As Brazilian President Dilma Rousseff promised to reduce Brazil’s greenhouse gas emissions by 43 per cent by 2030. Brazil became the first major developing country to pledge an absolute reduction in emissions over the next fifteen years. Since the country is an agricultural leader with abundant natural resources, it clearly has many challenges ahead. One of the questions that arises is whether it is possible to simultaneously promote economic growth and improve ecosystem protection within Brazil’s rural landscape.

How better price risk policy in Brazil could improve agricultural productivity

February 24, 2015 | and


Clarissa Costalonga e Gandour and Pedro Hemsley co-authored this post.

In Brazil’s agricultural sector, fluctuations in crop prices that are not mitigated by insurance or public policy can hinder farmers’ productivity and income, as well as the agriculture sector’s economic growth. For example, a farmer who makes planting decisions under the expectation of high harvest prices, which then fall short, can suffer severe losses. Understanding agricultural price volatility and mitigation is important to improving relevant public policy.

As part of CPI’s series of work on how to improve agricultural productivity while reducing deforestation in Brazil, we recently looked at agricultural price volatility, current policy to mitigate price risks, and what Brazil could do differently.

Our main finding is that current policy in Brazil does not meet farmers’ needs. The policy for price risk mitigation is based on direct government intervention in the market: when prices fall below a threshold, the government takes part of total output and allocates it out of the market. In 2013, the federal budget for price risk mitigation totaled BRL 5.4 billion, with over two fifths of it being destined for government buyouts and storage expenses. However, we find this policy yields only 8.03% of total production value, or BRL 4 billion per year in gains to producers of the four most important crops in Brazil – soybean, sugarcane, maize, and coffee.

Climate policy in 2014

February 14, 2014 |


Around the world, nations are striving to use increasingly scarce resources more productively, meet energy security goals, and reach economic growth targets, all while reducing climate risk. These are complex and urgent challenges, and policy plays a critical role in addressing them.

Since our inception in late 2009, Climate Policy Initiative has been working hard to answer pressing questions posed by decision makers through in-depth, objective analysis on some of the most significant energy and land use policies around the world, with a particular focus on finance.

As we continue to tackle these important and complex issues, your feedback on how we’re doing is extremely important. We hope you’ll help us reflect on the past, as we ring in a new year, by participating in a five-minute survey about our work.

How to spread new technology in agriculture: the importance of geographic conditions and learning-from-peers

November 7, 2013 |


In business, it is unusual to find a technology that proves to be better and costs less than the one in use. In theory, that technology should spread like wildfire and quickly replace current production methods. If it doesn’t, there is usually a barrier that prevents its spread.

In a new CPI study, we examine a farming technology called the Direct Planting System (DPS) which has proven to be one of the most important developments in agriculture in the past decades – however, after nearly forty years of its introduction in Southern Brazil, only 10% of Brazilian farmers reported using it in the 2006 Agricultural Census. The questions we address in this study are: What is keeping this technology from spreading and how do we overcome this barrier?

Our analysis reveals that soil composition is an important factor affecting the spread of the DPS. When soils are similar in a given municipality, it is easier for farmers to learn from the experience of peers who have already successfully adopted the system. Likewise, differences in the soil can act as a barrier to the expansion of DPS, since the system would have to be adapted to different soils.

How better monitoring and law enforcement saved 59,500 sq. km of the Amazon – an area the size of a small country

May 8, 2013 |


Clarissa Costalonga e Gandour also contributed to this piece.

The Amazon is the world’s largest rainforest, but protecting it from illegal deforestation is a challenge nearly as immense as the forest itself. In a previous study, CPI has discussed explanations for a slowdown in the rate of forest clearings observed in the 2000s. In a new study, DETERring Deforestation in the Brazilian Amazon, we take a step further and answer the question: Which specific policy efforts contributed most to the reduction in Amazon deforestation?

Our analysis reveals that the implementation of the Real Time System for Detection of Deforestation (DETER), a satellite-based system that enables frequent and quick identification of deforestation hot spots, greatly enhanced monitoring and targeting capacity, making it easier for law enforcers to act upon areas with illegal deforestation activity. This improvement in monitoring and law enforcement was the main driver of the 2000s deforestation slowdown.

Prior to the activation of DETER, Amazon monitoring depended on voluntary reports of threatened areas, making it difficult for law enforcement personnel to locate and access deforestation hot spots in a timely manner. With the adoption of the new remote sensing system, however, Brazilian law enforcement personnel were able to better identify, more closely monitor, and more quickly act upon areas with illegal deforestation activity.

Through empirical analysis, we estimate that DETER-based environmental monitoring and law enforcement policies prevented the clearing of over 59,500 km2 of Amazon forest area from 2007 through 2011. Deforestation observed during this period totaled 41,500 km2 – 59% less than in the absence of the policy change.

We also estimate that, in a hypothetical scenario in which monitoring and law enforcement was entirely absent from the Amazon, an additional 122,700 km2 of Amazon forest would have been cleared from 2007 through 2011. To put that figure in context, that’s an area larger than the total land mass of the country of Nicaragua.

Does credit affect deforestation? Evidence from a rural credit policy in the Brazilian Amazon

March 18, 2013 |


Clarissa Costalonga e Gandour also contributed to this piece, which was originally posted on Climate-Eval.

The deforestation rate in the Brazilian Amazon decreased sharply in the second half of the 2000s, falling from a peak of 27,000 km2 in 2004 to 5,000 km2 in 2011. In a previous CPI/NAPC study [Assunção et al. (2012)], we estimated that conservation policies introduced in the mid to late 2000s prevented the loss of approximately 62,000 km2 of forest in the 2005 through 2009 period. We’ve recently taken a closer look at one of these policies — National Monetary Council Resolution 3,545.

Introduced in mid-2008, Resolution 3,545 placed a condition on rural credit, an important source of financing for rural producers, in the Brazilian Amazon Biome. To get credit, borrowers had to present proof of compliance with environmental regulations, the legitimacy of their land claims, and the regularity of their rural establishments. To prove credit eligibility, Resolution 3,545 required borrowers to present a series of documents. Such documentation, however, varied according to borrower profiles, with small-scale producers subject to less stringent requirements. Resolution 3,545 represented a restriction on official rural credit — and thereby on the fraction of rural credit that is largely subsidized via lower interest rates — while other sources of financing for agricultural activity suffered no such restriction.

Policy Watch: UN climate talks wrap up, Indonesia approves landmark forest protection deal, and Africa’s largest solar plant close to breaking ground

December 11, 2012 |


This week, climate policy headlines from around the world include results from the UN climate talks, Indonesia approving a conservation deal that will protect 200,000 acres of forest, and Norway contributing $180 million to help Brazil slow deforestation.

Elinor Benami, Chiara Trabacchi, and Xueying Wang contributed headlines to this edition of Policy Watch.

UN climate talks extend Kyoto Protocol, promise compensation
The summit established for the first time that rich nations should move towards compensating poor nations for losses due to climate change. Developing nations hailed it as a breakthrough, but condemned the gulf between the science of climate change and political attempts to tackle it.

The deal, agreed by nearly 200 nations, extends to 2020 the Kyoto Protocol. It is the only legally-binding plan for combating global warming. The deal covers Europe and Australia, whose share of world greenhouse gas emissions is less than 15%.

But the conference also cleared the way for the Kyoto protocol to be replaced by a new treaty binding all rich and poor nations together by 2015 to tackle climate change. The final text “encourages” rich nations to mobilize at least $10bn (£6bn) a year up to 2020, when the new global climate agreement is due to kick in. Full article.
