Animal welfare monitoring relies on sensor accuracy for detecting changes in animal well-being. We compared the distance calculations based on global positioning system (GPS) data alone or combined with motion data from triaxial accelerometers. The assessment involved static trackers placed outdoors or indoors vs. trackers mounted on cows grazing on pasture. Trackers communicated motion data at 1 min intervals and GPS positions at 15 min intervals for seven days. Daily distance walked was determined using the following: (1) raw GPS data (RawDist), (2) data with erroneous GPS locations removed (CorrectedDist), or (3) data with erroneous GPS locations removed, combined with the exclusion of GPS data associated with no motion reading (CorrectedDist_Act). Distances were analyzed via one-way ANOVA to compare the effects of tracker placement (Indoor, Outdoor, or Animal). No difference was detected between the tracker placement for RawDist. The computation of CorrectedDist differed between the tracker placements. However, due to the random error of GPS measurements, CorrectedDist for Indoor static trackers differed from zero. The walking distance calculated by CorrectedDist_Act differed between the tracker placements, with distances for static trackers not differing from zero. The fusion of GPS and accelerometer data better detected animal welfare implications related to immobility in grazing cattle.

Accelerated climate change is a global challenge that is increasingly putting pressure on the sustainability of livestock production systems that heavily depend on rangeland ecosystems. Rangeland management practices have low potential to sequester greenhouse gases. However, mismanagement of rangelands and their conversion into ex-urban, urban, and industrial landscapes can significantly exacerbate the climate change process. Under conditions of more droughts, heat waves, and other extreme weather events, management of risks (climate, biological, financial, political) will probably be more important to the sustainability of ranching than capability to expand output of livestock products in response to rising demand due to population growth. Replacing traditional domestic livestock with a combination of highly adapted livestock and game animals valued for both hunting and meat may be the best strategy on many arid rangelands. Eventually, traditional ranching could become financially unsound across large areas if climate change is not adequately addressed. Rangeland policy, management, and research will need to be heavily focused on the climate change problem.

Interest in farmland is rising. And, given commodity price volatility, growing human and environmental pressures, and worries about food security, this interest will increase, especially in the developing world. One of the highest development priorities in the world must be to improve smallholder agricultural productivity, especially in Africa. Smallholder productivity is essential for reducing poverty and hunger, and more and better investment in agricultural technology, infrastructure, and market access for poor farmers is urgently needed. When done right, larger-scale farming systems can also have a place as one of many tools to promote sustainable agricultural and rural development, and can directly support smallholder productivity, for example, throughout grower programs. However, recent press and other reports about actual or proposed large farmland acquisition by big investors have raised serious concerns about the danger of neglecting local rights and other problems. They have also raised questions about the extent to which such transactions can provide long-term benefits to local populations and contribute to poverty reduction and sustainable development. Although these reports are worrying, the lack of reliable information has made it difficult to understand what has been actually happening. Against this backdrop, the World Bank, under the leadership of Managing Director Ngozi Okonjo-Iweala, along with other development partners, has highlighted the need for good empirical evidence to inform decision makers, especially in developing countries.

Brazil has the second-largest cattle herd in the world and is a major exporter of beef. While ranching in the Amazon-and its destructive environmental consequences-receives attention from both the media and scholars, the states of Mato Grosso and Mato Grosso do Sul actually host the most cattle. A significant beef producer in Brazil beginning in the late nineteenth century, the region served as a laboratory for raising cattle in the tropics, where temperate zone ranching practices do not work. Mato Grosso ranchers and cowboys transformed ranching's relationship with the environment, including the introduction of an exotic cattle breed-the Zebu-that now dominates Latin American tropical ranching. Cattle in the Backlandspresents a comprehensive history of ranching in Mato Grosso. Using extensive primary sources, Robert W. Wilcox explores three key aspects: the economic transformation of a remote frontier region through modern technical inputs; the resulting social changes, especially in labor structures and land tenure; and environmental factors, including the long-term impact of ranching on ecosystems, which, he contends, was not as detrimental as might be assumed. Wilcox demonstrates that ranching practices in Mato Grosso set the parameters for tropical beef production in Brazil and throughout Latin America. As the region was incorporated into national and international economic structures, its ranching industry experienced the entry of foreign investment, the introduction of capitalized processing facilities, and nascent discussions of ecological impacts-developments that later affected many sectors of the Brazilian economy.

1. As tropical cattle ranching continues to expand, successful conservation will require an improved understanding of the relative impacts of different livestock systems and landscape structure on biodiversity. Here, we provide the first empirical and multi-scale assessment of the relative effects of livestock intensification and landscape structure on biodiversity in the threatened tropical dry forests of Mesoamerica. 2. We used a dataset of dung beetles (169,372 individuals from 33 species) collected from 201-km² landscapes, ranging from zero-yielding forest sites to high-yield cattle ranches and maize farms, to investigate the relative effect of livestock intensification (net cattle production; macrocyclic lactone use; annual dung production) landscape structure (landscape composition and configuration) at multiple spatial scales on different attributes of dung beetle communities using a multi-model averaging approach. 3. Dung beetle species richness, biomass and composition were more strongly related to landscape structure than to livestock intensification. 4. Forest cover was the best predictor of dung beetle assemblages, being positively related to species diversity and biomass across multiple spatial scales. The use of macrocyclic lactones was strong and negatively related to dung beetle communities at the local scale. 5. Synthesis and applications: Maximising forest protection through a \"land sparing\" strategy is likely to be the best strategy for reducing negative impacts of cattle farming on Neotropical dung beetle communities. However, increasing or maintaining yields while reducing agrochemical inputs will be important for conserving onfarm biodiversity and the ecosystem services that dung beetles provide in livestock-dominated landscapes.

How the arrival of cattle transformed life and society in the Americas In this book, Nicolas Delsol compares zooarchaeological and material evidence from sites across Mesoamerica and the Caribbean to show how the introduction of cattle, beginning with imports by Spanish colonizers in the 1500s, shaped colonial American society. Before European colonization, cows were vital in European and African societies but were unknown to the Native communities of the Western Hemisphere. This book traces their impact in the Americas by using a broad range of methods, such as ancient DNA analyses on faunal collections from major postcolumbian sites. Delsol describes the place of cattle in the colonial culture and landscape, beginning with the transportation of cattle across the Atlantic and moving to herding practices in new habitats, butchery techniques, and the production, trading, and use of cow byproducts. Cattle in the Postcolumbian Americas is the first large-scale regional archaeological study of the introduction of a European domesticated species to the Americas. Using both zooarchaeological and historical data, Delsol argues that the arrival of cattle was a major consequence of European colonization with effects that have often been overlooked.

A growing population with increasing consumption of milk and dairy require more agricultural output in the coming years, which potentially competes with forests and other natural habitats. This issue is particularly salient in the tropics, where deforestation has traditionally generated cattle pastures and other commodity crops such as corn and soy. The purpose of this article is to review the concepts and discussion associated with reconciling food production and conservation, and in particular with regards to cattle production, including the concepts of land-sparing and land-sharing. We then present these concepts in the specific context of Colombia, where there are efforts to increase both cattle production and protect tropical forests, in order to discuss the potential for landscape planning for sustainable cattle production. We outline a national planning approach, which includes disaggregating the diverse cattle sector and production types, identifying biophysical, and economic opportunities and barriers for sustainable intensification in cattle ranching, and analyzing areas suitable for habitat restoration and conservation, in order to plan for both land-sparing and land-sharing strategies. This approach can be used in other contexts across the world where there is a need to incorporate cattle production into national goals for carbon sequestration and habitat restoration and conservation.

In North America, the introduction of livestock as part of the Columbian Exchange had profound social and ecological consequences for cultural environments, yet the landscape impacts of these animals have been difficult to identify, particularly in the first decades of sustained contact. Between 1701 and 1775, at a Spanish colonial mission near what is today Nogales, Arizona, O'odham groups and Spanish missionaries generated land management practices that wove together the needs of domesticated animals and existing Indigenous farming practices. This study proposes a set of indicators to identify animal husbandry practices in both the archaeological and historical record. Faunal, isotopic, and historical analyses from Mission Los Santos Ángeles de Guevavi provide evidence that cattle ages were loosely monitored and that cattle were culled at an older age than optimal for meat and grease extractive strategies compared to other domesticated species at the site. These findings suggest a low investment strategy in cattle, which may have helped Indigenous groups continue aspects of precontact agricultural and gathering practices and preserve their communities in the colonial period. These findings provide further evidence of the depth of animal husbandry practices among Indigenous groups in the Southwest.

Agriculture and extensive cattle ranching have been leading causes of deforestation in the rainforests of the Mexican tropics. In the municipality of Jesús Carranza, Veracruz, extensive cattle ranching became the primary activity and income source about 50 years ago, subsequent to forest clearing for agriculture 20 years earlier. However, remnant and newly planted trees are part of the landscape, both within pastures for shade, and in living fences. This study documents local knowledge on tree utility, combined with an analysis of management practices in pastures. It evaluates the reasons given by usufruct rights holders, ejidatarios, to retain or plant trees in their pastures. The data were obtained through semi-structured interviews and participatory workshops from 35 ejidatarios in two villages. The main reasons given for maintaining trees were for shade, firewood, timber, and fruits. Some also mentioned conservation as an objective on its own. The members of the more well-to-do ejido emphasized the ease of tree propagation as a main rationale for tree maintenance, whereas the less well-off ejido members thought timber value was an important criterion. All ejidatarios were interested in having trees for their environmental, social, and economic benefits, and were influenced by outside information on conservation issues. This change in attitudes represents an opportunity for increased experimentation with silvopastoral systems.
