Grazing game: a learning tool for adaptive management in response to climate variability in semiarid areas of Ghana Ecology and Society
Villamor, Grace B; Department of Ecology and Natural Resources Management, Center for Development Research, University of Bonn; gracev@uni-bonn.de; Badmos, Biola K; Kwara State University, Malete, Nigeria; biolakz@yahoo.com.
In West Africa, the most extreme predicted effects of climate change are expected to occur in desert and grassland areas. It is crucial for local populations in this region to better understand what such projections signify to them to identify sound adaptation policies and interventions. We developed a game, called the “grazing game,” and conducted trials with local farmers at multiple study sites as a learning tool to better understand their behavior in response to climate variability under semiarid conditions in West Africa and to facilitate social learning. The grazing game was designed to reveal the processes that lead to overgrazing and desertification based on the players’ interactions with environmental conditions and...

Pecuária de corte no Brasil Central: o produtor, os recursos produtivos e o manejo das pastagens. Infoteca-e
COSTA, F. P..
Problemas técnicos relacionados ao manejo das pastagens vêm sendo estudados com grande frequencia e profundidade. Pouco esforço, porém, tem sido dirigido para entender as ações e motivações dos produtores, relacionadas a tal manejo. O presente trabalho e um estudo exploratório neste sentido, apresentando o resultado de um levantamento realizado em uma amostra de 100 pecuaristas de corte da microrregião homogênea Pastoril de Campo Grande, no Estado de Mato Grosso do Sul. As entrevistas tiveram como base um questionário englobando os seguintes tópicos: características gerais dos produtores e suas preferências na aplicação dos recursos financeiros; disponibilidade e uso dos recursos produtivos, incluindo pastagens e alimentação suplementar, bovino, máquinas,...

Effects of Cutting and Grazing on Vegetation and Productivity of Shrub-steppe in the Loess Plateau, North-west China OAK
Hongo, Akio; Cheng, Jimin; Ichizen, Nobumasa; Toukura, Yuji; Devee, Enkhee; Akimoto, Masahiro; 本江, 昭夫; 程, 積民; 一前, 宣正; 藤倉, 雄司; デビィ, エンク; 秋本, 正博.
The Loess Plateau, situated in north-west China, has been subjected to degradation of vegetation owing to overgrazing. In order to clarify the effects of grazing and cutting on vegetation and productivity of shrub-steppe, the study was carried out from May in 1989 to October in 1991 in the Pastoral Preserving Zone of Yunwu Mountain. The vegetation was monthly surveyed, and DM weights of dominant species were separately measured. Soil samples were taken at three selected sites and one overgrazed site and these chemical analysis were made. Relative abundance of species was calculated on the base of the total frequency of 7835. Gramineae showed the highest value (26 %), followed by Compositae (24 %) and Leguminosae (12 %). During 3 experimental years, the...

Segregation of patches by patterns of soil attributes in a native grassland in central Argentina Phyton
Villamil,MB; Amiotti,NM; Peinemann,N.
Demand for greater cattle production at the El Caldenal area in central Argentina has resulted in overgrazing in a patchy grassland structure. Patches are clearly identified on the basis of dominant plant species resulting from their grazing history. Our primary objective was to examine the influence of individual plants at each patch on the local multivariate pattern of soil nutrients, assessing the magnitude of the association between the concentration of nutrients in the plant and its underlying soil. Canonical discriminant analysis highlighted the important role of soil organic matter, available P, and Zn content of soils to segregate among patches. The canonical correlation analysis between soil and plant variables revealed a significant association...

Changes in attributes of soils subjected to fallow in desertification hotspot Rev. Ciênc. Agron.
Ferreira,Mirele Paula da Silva; Artur,Adriana Guirado; Queiroz,Hermano Melo; Romero,Ricardo Espíndola; Costa,Mirian Cristina Gomes.
ABSTRACT Soils in semi-arid regions have been degraded by overgrazing, which reduces the production capacity and, in certain situations, leads to desertification. An alternative to recover degraded areas is the fallow period, which works through the resilience of the soil itself, increasing the supply of organic matter and improving soil physical properties. Thus, the objective of this study was to test the hypothesis that 14-year grazing exclusion improves soil physical and chemical attributes in degraded areas under desertification. The study was conducted in Irauçuba, Ceará State, Brazil. The experimental design was completely randomized, in a 4 x 2 factorial scheme corresponding to four areas and two managements (overgrazing and fallow), with four...
