Persistence of cattle ranching in the Brazilian Amazon: A spatial analysis of the rationale for beef production

Fed by demand for beef within Brazil and in global markets, the Brazilian herd grew from 147 million head of cattle in 1990 to ≈200 million in 2007. Eighty-three percent of this expansion occurred in the Amazon and this trend is expected to continue as the industry bounces back from a recent agricultural downturn. Intensification of the cattle industry has been suggested as one way to reduce pressure on forest margins and spare land for soybean or sugarcane production, and is the cornerstone of Brazil's plan for mitigation of greenhouse gas emissions. To this end, federal credit programs and research and development activities in Brazil are aligning to support intensification goals, but there is no guarantee that this push for intensification will decrease the demand for land at the forest margin and as result curb CO₂ emissions from deforestation. In this paper we use a spatially explicit rent model which incorporates the local effects of biophysical characteristics, infrastructure, land prices, and distance to markets and slaughterhouses to calculate 30-year Net Present Values (NPVs) of extensive cattle ranching across the Brazilian Amazon. We use the model to ask where extensive ranching is profitable and how land acquisition affects profitability. We estimate that between 17% and 80% of land in the Amazon would have moderate to high NPVs when ranched extensively if it were settled, i.e. if the rancher does not buy the land but acquires it through land grabbing. In addition, we estimate that between 9% and 13% of land in the Amazon is vulnerable to speculation (i.e. areas with positive NPVs only if land is settled and not purchased), which suggests that land speculation is an important driver of extensive ranching profitability, and may continue to be in the future. These results suggest that pro-intensification policies such as credit provision for improved pasture management and investment in more intensive production systems must be accompanied by implementation and enforcement of policies that alter the incentives to clear forest for pasture, discourage land speculation, and increase accountability for land management practices if intensification of the cattle sector is to deter new deforestation and displace production from low-yield, extensive cattle production systems in frontier regions of the Brazilian Amazon.     

Crossing spatial analyses and livestock economics to understand deforestation processes in the Brazilian Amazon: the case of São Félix do Xingú in South Pará

The Amazon is the largest tropical forest area on Earth, and has been undergoing rapid deforestation for the last four decades. In the Brazilian Amazon, large‐scale pasture for cattle ranching and soybean production are the main land uses, leading to a yearly deforestation rate of 0.5%. These conversions are mostly located in frontier areas distributed along the so‐called “arc of deforestation”. Within this large zone, various land use change processes are interacting through several modes of land valuation and organisation. From several case studies in the State of Pará (Brazil), the current project aims at analysing how landscape dynamics are related to infrastructure development, ecological conditions, zoning policies and to the evolution and the organisation of the production, consumption and marketing chains of livestock products. This paper presents the results for one test site, the region of São Félix do Xingú, South of Pará This region is the focus of land speculation, cattle expansion, and deforestation. Road construction, investments in electrical energy, financial credit for cattle, and the land reform policies have all fuelled this process. All these factors make this region one of the most dynamic agricultural frontiers in the Brazilian Amazon. The main objective of the paper is to improve our understanding of deforestation processes by crossing spatial analyses and 1ivestock economics.studies, and to characterise the role and impact of various natural and anthropic factors in the location and development of the main types of farmers, and their policy implications.     

Solving Brazil's land use puzzle: Increasing production and slowing Amazon deforestation

Brazil has become an agricultural powerhouse, producing roughly 30 % of the world’s soy and 15 % of its beef by 2013 – yet historically much of that growth has come at the expense of its native ecosystems. Since 1985, pastures and croplands have replaced nearly 65 Mha of forests and savannas in the legal Amazon. A growing body of work suggests that this paradigm of horizontal expansion of agriculture over ecosystems is outdated and brings negative social and environmental outcomes. Here we propose four strategies that can reduce deforestation, while increasing production and social wellbeing. First, eliminate land grabbing and land speculation through designation of public forests. This would clarify land tenure and limit the pool of land available for uncontrolled expansion of agriculture and ranching. Second, reduce deforestation on private properties by implementing existing mechanisms in Brazil’s Forest Code to facilitate payments for environmental services, with support from market initiatives for sustainable sourcing of agricultural products. Third, incentivize increased productivity on medium and large properties through targeted investments. By stimulating adoption of proven technologies for sustainable intensification, this would help meet Brazil’s production targets and growing international demand for agricultural products, without expanding into new production areas. Finally, foster economic, environmental and social improvements through technical assistance to small farmers. Small farmers occupy a large swath of the Amazon and often lack access to technical assistance, production technology, and markets. Providing quality technical assistance to small farmers could help them better align production practices with local opportunities; increase household income and improve livelihoods; and reduce deforestation pressure. By implementing these four strategies in a coordinated effort between public and private agents, Brazil can show the world how to reduce deforestation while increasing agricultural output, reestablishing its leadership in managing natural resources and mitigating climate change.     

Controlling deforestation in the Brazilian Amazon: Regional economic impacts and land-use change

Brazil confirmed targets for reducing greenhouse gas emissions in 2008, including an 80% reduction in deforestation in the Amazon by 2020. With this in mind, we investigated the trade-off between environmental conservation and economic growth in the Amazon. The aim of this study is to project the economic losses and land-use changes resulting from a policy to control deforestation and the rise in land productivity that is necessary to offset those losses. We developed a Dynamic Interregional Computable General Equilibrium Model for 30 Amazon regions with a land module allowing conversion between types of land. The results have shown that the most affected regions would be soybeans and cattle producers as well as regions dominated by family farms. To offset these impacts, it was estimated that an annual gain of land productivity of approximately 1.4% would be required.     

Forests or fields? A response to the theory that tropical forest conservation poses a threat to the poor

A rebuttal is provided of David Wood's proposal to open up tropical forests to agricultural uses. Concern is raised that his proposal exaggerates the ability of forests to regenerate after agricultural uses, sacrifices tropical forests in the name of alleviating poverty and in support of large land owners, and prevents valuable potential resource use by local populations. There is misunderstanding by Wood of conservationists' postures and the cause of current deforestation. In Brazil, deforestation has occurred primarily for low productivity cattle pasture (62% of all private land in the Amazon region in ranches over 1000 hectares-ha). Only 11% of private Amazonian land was in farms of less than 100 ha; only 30% of this size farm area was involved in 1991 in deforestation, while 70% of deforestation took place on ranches over 100 ha. Mass migrations of Brazil's population from the northeast to the Transamazon Highway and from Parana to Rondonia were impelled by increasing concentration of land tenure in migrant areas, and not by population growth. The rate of deforestation has slowed due to the economic recession. A World Bank study indicates that redistributing unproductive large landholdings in northeastern Brazil would increase agricultural output by 80%. The agricultural productivity of tropic areas is not as assured; Wood's support is based on preliminary findings, which are being revised with more cautionary thinking. Wood also understates the maintenance of soil fertility with fertilizers. The issue of scale also affects the use of agroforestry and perennial crop plantations such as rubber and cacao, which can only absorb the production of small areas, due to marketing constraints and physical resource limitations. Conservationists have not effectively redirected World Bank efforts to protect environments and help the impoverished, as suggested by Wood. Forest recovery has been very slow in large cattle pastures, and would take thousands of years if the land is left undisturbed. Recovery even under traditional shifting cultivation schemes is slower than Wood recognizes. Wood's argument that deforestation is temporary is not sufficient to invalidate the claim for conservation now. Reallocation is really the same as land extensification; current practices in Brazil will not support large human populations. The solution is to develop environmental services and find other means to support rural populations in urban areas.     

Land governance as a precondition for decreasing deforestation in the Brazilian Amazon

This paper’s aim is to show that improvements in land governance in Brazil, and particularly in the Amazon region, have been the main pre-condition enabling reductions in deforestation of the Amazon rainforest. Deforestation occurs primarily where property rights are not clearly established, and occurs mostly on land directly or indirectly under state responsibility. This paper also shows that land speculation plays an important role in deforestation. Based on these findings, it is evident that Brazil must improve its land governance in order to decrease rates of deforestation. The Brazilian government has adopted important new efforts to improve land administration, including improvements in the registration process and the Terra Legal program, which are addressing public land problems across large areas of the Amazon. The concluding section highlights how efforts to reduce deforestation will only be possible through more efficient land governance, especially in the Amazon region, and discusses the important role that participatory land governance may play in improving land use and land ownership through application of land taxes.

The impact of commodity price and conservation policy scenarios on deforestation and agricultural land use in a frontier area within the Amazon

Deforestation in the Amazon is caused by the complex interplay of different drivers. Price of commodities such as beef and soya, and incoming migration are paramount factors. Construction of new highways is a key aspect, as they enable a growing flow of people and economic activities, provoking an intensification of the conversion of forests into pasture and agricultural areas. The pavement of road BR-163 accelerates the expansion of the agricultural frontier from the state of Mato Grosso to Pará, inside the Amazon. Today, the Brazilian government applies two main kinds of policies to protect the environment. First by establishing conservation units (CUs) that include an array of reserve types from natural areas to indigenous lands, and second by enforcing the Forest Code (FC), a law that limits the occupation and use of forests. Legal reserve requirements for rural properties are 80% in the Amazon rainforest, 35% in the Cerrado shrublands and 20% in other regions. However, the effectiveness of these policies relies on a fragile institutional capacity, which causes a flawed monitoring, law enforcement and control. To assess the impact of effective conservation policies on land use and deforestation by 2020, we used the LUSMAPA model in combination with two scenarios, one that included different commodity price developments and migration rates and one on the assumption of the institutional strength to uphold the conservation policies. A revision of the FC from an average 80% policy target to 60% effective implementation and disregard borders of CUs by allowing 5% deforestation in CUs, that both corresponds to a ‘weak’ governmental enforcement, leads to additional deforestation of 41–57%, depending on the commodity price scenario. The results of the simulations are discussed in the light of recent policy changes in Brazil.     

Dynamic adjustment in the US beef market with imports

This paper hypothesizes that while there are important qualitative differences in domestic beef and imported beef, beef and cattle imports also represent attempts by the US beef processing and wholesale sector to adjust to short-run changes in supply and demand. Dynamic production theory is applied to the problem to test for this adjustment process, and presents a production theory approach to meat trade that has previously been included in demand functions. The results of this analysis suggest that the method used provides a reasonable and appropriate representation of the import behavior of the US processing and wholesale beef sector.     

Towards zero deforestation and forest restoration in the Amazon region of Maranhão state,Brazil

The Amazon forest in the state of Maranhão ensures ecosystem services that directly and indirectly affect the life quality of its population and economy, via hydrologic and climatic regulation, among other benefits. Currently, only 25% of the original forest cover (24.7 thousand km²) remains while illegal deforestation persists in a violent process that provokes visible social, economic and environmental harm. Simultaneously, Maranhão has seen record levels of burning, faces a water shortage and fights against the worst social and economic indicators in the country. Conversely, secondary vegetation covers 19.9 thousand km² (27% of deforested area) and is completely unprotected. Contrary to the international commitments assumed by Brazil to combat deforestation and restore forests, some of the political representatives of Maranhão have sought legal mechanisms to further diminish forest cover in public and private areas. To promote the conservation and restoration of Maranhão Amazon Forest, a multi-institutional network of researchers was established in 2015. This viewpoint paper aims to draw attention to this endangered region of the Brazilian Amazon and give science-oriented recommendations to policy makers in order to avoid more setbacks. We argue that Maranhão state must urgently establish a policy of Zero Deforestation, protect secondary forests and comply with the national forest restoration policy, thus ensuring long-term economic sustainability.     

Land occupations and deforestation in the Brazilian Amazon

Researchers are increasingly interested in understanding the impact of contentious social processes on land change. In the Brazilian Amazon, there are often contentious interactions between landholders defending private property rights and squatters who have the right to occupy land that is deemed unproductive. Previous studies suggest that the contentious social processes inherent in the Brazilian land tenure and land reform system cause a significant amount of deforestation. An environment of insecure land title, and policies that value deforested land over forested land, among other factors, encourage both landholders and squatters to deforest more land than is necessary for pasture or crop production. This paper examines the impact that land occupations have on deforestation at the municipal scale across the Brazilian Legal Amazon, from 2000 to 2009. We show that land occupations have a direct influence on deforestation. We use spatial analysis as well to show that land occupations have a spatial component in the effect on deforestation: occupations in one municipality affect deforestation in adjacent areas.     

Amazon forest on the edge of collapse in the Maranhão State,Brazil

The year 2019 in Brazil was marked by environmental setbacks, which catalyzed the increase of illegal deforestation and fire rates in the Brazilian Amazon. In the Amazon region of Maranhão state, original forest cover diminished from 25 % (24,700 km²) in 2016 to 24 % (23,967 km²) in 2019, and 6,038 km² of remaining forests were degraded by fires and/or illegal logging – processes related to high levels of violence against indigenous and rural communities. Almost half of all deforested areas in the region (36,060 km²) are considered a global restoration hotspot, however secondary vegetation remains unprotected and 8,294 km² were cleared between 2014 and 2018. Due to uncontrolled deforestation and fragmentation, Maranhão has no more forest core areas (outside protected areas) with the minimum size to ensure sustainable forest management practices for timber production. New policies at the state level must promote old-growth and secondary forest conservation and restoration. However, the trends point to the opposite direction: the Ecological-Economic Zoning (ZEE) allows the reduction of forest protection and the State Forest Policy reinforces federal legislation setbacks. The Amazon region of Maranhão state has forest aptitude, and forest and agroforestry product chains would bring social and environmental benefits, making them the best opportunity for sustainable economic development in the region. Therefore, the forest must be re-planted for the benefit of people and nature.     

Policy options towards deforestation reduction in Cameroon: An analysis based on a systematic approach

This study advances measures that can combat deforestation in Cameroon. It also looks at possible carbon dioxide (CO₂) emission reductions and the effects on gross domestic product (GDP) and employment based on selected baseline scenarios based on reductions in deforestation. A systematic approach of analyzing the drivers, agents, socio-economic context, political context, spatial context of deforestation and specific and general deforestation reduction policies is used. The final step of the approach is to verify the repercussions of deforestation reduction on CO₂ emissions, employment and GDP. Monitoring population growth and arable production through intensification of production is promising. The general policies that this study postulates are enforcement, legal adherence, specification of tasks and quotas, collaboration, forest licensing and monitoring. More specific policies could be within the reduction of emissions from deforestation and forest degradation mechanism (REDD+) as well as diversification of livelihoods, mechanization, use of fertilizers and intensive cattle farming inter alia. Reductions in deforestation will reduce atmospheric CO₂, employment in the forestry sector and the share of forestry's contribution to GDP.     

Comparative Advantage Indices of Selected Livestock Production Sectors in Brunei Darussalam

Abstract

This study calculates the protection rates and comparative advantage indices of livestock industry in Brunei from an import substitution perspective. Four livestock sub-sectors were being evaluated: broiler, layer, goat and beef cattle. Two measures of government intervention indices were calculated, namely nominal protection rate (NPR) and effective protection rate (EPR). Domestic resource cost (DRC) and resource cost ratio (RCR) indices were computed to determine the comparative advantages of the livestock industry. In general, the results indicate that the livestock industry in Brunei was heavily protected. The study revealed the existence of comparative advantage only for very large farms producing poultry meat and eggs. Similarly in the ruminant sector, goat production appears to have comparative advantage over beef cattle. Small and medium poultry farms and large non-ruminant farms and cattle beef production possess comparative disadvantage despite being highly protected industries.     

Determinants of crop-livestock integration in Brazil: Evidence from the household and regional levels

Integrated crop-livestock systems (iCL) are advocated as a promising strategy to increase agricultural production and rehabilitate degraded pastures while mitigating GHG emissions. Although iCL in Brazil has increased over the past few years, it still occupies a small share of the country’s total agricultural area. We investigate the determinants of iCL occurrence in Mato Grosso state, a globally important producer of beef cattle and grains that has experienced rapid land cover change and environmental degradation in recent decades. Our analysis encompasses two typical cases of iCL in Mato Grosso (the rotation of soy followed by pasture, and soy followed by maize and pasture) as well as biophysical, socioeconomic, and institutional factors observable at the household and/or municipality levels that may influence the wide-scale occurrence of iCL. Evidence at both scales suggests that knowledge and supply chain infrastructure play an important role in early occurrence of iCL, as they are more common in regions closer to iCL research stations and processing facilities of grains and cattle. On average iCL adopters are more educated and have better access to technical assistance and sector information than specialized farmers or ranchers. Most iCLs are concentrated near established soy areas and greater similarity exists between municipalities with iCL and soy-dominant municipalities vs. pasture-dominant municipalities. Our findings reveal the importance of specific conditions for iCL occurrence and iCL promotion in livestock-dominant regions. Incentives targeted at ranchers are crucial for the achievement of the Brazilian Government’s goal to restore degraded pastures through agricultural intensification.

COVID-19 and the Canadian cattle/beef sector: Some preliminary analysis

Canada's cattle/beef sector has already weathered a shock after a 2003 case of BSE resulted in closed borders and industry restructuring. Now, the sector has to adjust to similar shocks due to COVID-19. This paper examines the supply chain from the consumer up to the cow–calf producer by considering consumer reactions, labor market constraints, and supply response. A quarterly market model of North American cattle and beef markets is used to examine price and revenue impacts associated with the market disruptions. Depending on the scenario, there is considerable price and revenue suppression at all levels of the market.     

Impacts of Declining U.S. Retail Beef Demand on Farm-Level Beef Prices and Production

A systems model was estimated to determine the effects of declining U.S. retail beef demand on farm-level beef prices and production. Retail beef demand declined by nearly 66% from 1976 to 1999. Results indicate autonomous shifts in retail demand significantly impacted farm-level demands and production. Based on equilibrium multipliers, the 1976–99 reduction in beef demand decreased real slaughter cattle prices and production by 32.1% and 11.2%, respectively. Real feeder cattle prices and production decreased by 8.0% and 22.6%, respectively. Combining the decreases in farm prices and production, slaughter and feeder cattle producers experienced a real revenue reduction of $13.3 billion (61%) due to the long-term decline in demand.     

Amazonian indigenous peoples are threatened by Brazil’s Highway BR-319

The Amazon rainforest in Brazil is under the greatest human pressure in its history. This pressure is increasing under the current presidential administration, with proposed retraction of environmental and humanitarian protections. Among these pressures are new hydroelectric dams, railways and highways. An infrastructure project with especially far-reaching consequences is the reopening of Highway BR-319 right through the heart of the Amazon Forest. The highway connects Manaus in central Amazonia to Porto Velho in the “arc of deforestation” on the southern edge of the forest. The highway crosses one of the most conserved parts of the Amazon with a large concentration of Indigenous Lands (“Terras Indígenas”). Although Brazil is a signatory to ILO Convention 169, which establishes the need for consultation with indigenous peoples and traditional communities, consultations have so far not been held. Here we argue for the need for consultation of all indigenous peoples within 150 km of any part of the highway, comprising 63 Indigenous lands and five other areas containing indigenous communities that are directly threatened by the project.
