&amp;#8220;A shepherd has to invent&amp;#8221;:  Poetic analysis of social-ecological change in the cultural landscape of the central Spanish Pyrenees

Since the mid-20th century, the Pyrenean pastoral social-ecological system (SES) has undergone socioeconomic and demographic transformations leading to changes in grazing practices and a decline in the livestock industry. Land abandonment has contributed to an ecological transition from herbaceous vegetation cover to shrublands and forests, leading to a loss of ecosystem services, including biodiversity and forage. I interviewed 27 stockmen (ganaderos) in two valleys of the central Pyrenees to document their traditional ecological knowledge and observations of environmental, social, economic, and cultural changes in the valleys. I used poetic analysis, a qualitative data analysis approach, to illustrate and analyze one ganadero&amp;#8217;s experience of...

In the past decades, social-ecological systems (SESs) worldwide have undergone dramatic transformations with often detrimental consequences for livelihoods. Although resilience thinking offers promising conceptual frameworks to understand SES transformations, empirical resilience assessments of real-world SESs are still rare because SES complexity requires integrating knowledge, theories, and approaches from different disciplines. Taking up this challenge, we empirically assess the resilience of a South African pastoral SES to drought using various methods from natural and social sciences. In the ecological subsystem, we analyze rangelands&amp;#8217; ability to buffer drought effects on forage provision, using soil and vegetation indicators. In the social...

Provedor de dados: 14
Autores: SANTOS, S. A.; COSTA, C.; CRISPIM, S. M. A.; PELLEGRIN, L. A.; RAVAGLIA, E.
Este estudo teve como finalidade avaliar as variações mensais da capacidade de suporte de uma área no Pantanal, e propor um cálculo geral de estimativa da capacidade de suporte para as pastagens nativas, com base na produtividade e seletividade das forrageiras existentes nas unidades de paisagem preferidas por bovinos na subregião da Nhecolândia, Pantanal. O estudo foi efetuado numa área de 151 ha, com rebanho de 46 vacas de cria, no período de outubro de 1997 a setembro de 1999. Foram avaliados mensalmente a produção de matéria seca total nas unidades de campo limpo e baixadas, e as respectivas produções de matéria seca total e selecionada dos principais sítios utilizados para pastejo. Um algoritmo foi aplicado para a obtenção das estimativas da...

Fatores morfológicos que interferem na seleção de forrageiras pelos herbívoros.
Provedor de dados: 14
Autores: LEITE, E. R.; MESQUITA, R. C. M.
A composicao de dietas selecionadas pelos herbivoros tem sidomateria de grande interesse para os pesquisadores de pastagens nativas.As razoes pelas quais os animais selecionam uma dada planta, ou partes dela, consistem em quatro parametros morfologicos: tamanho do corpo, tipo de sistema digestivo (cecal ou rumiante), relacao entre o volume rumino-reticular e o peso do animal, e tamanho da boca, o tamanho e o tipo de sistema digestivo determinam o tempo e a energia dispendidos para que o herbivoro pasteje seletivamente; a relacao entre o volume rumino-reticular e o peso corporal determina o tipo de alimento que o ruminante processo mais eficientemente, e o tamanho da boca determina a habilidade do herbivoro em selecionar partes de uma determinada planta.

Climatic variability and cooperation in rangeland management: a case study from Niger
Provedor de dados: 31
Autores: McCarthy,   Nancy; Vanderlinden,   Jean-Paul.
In this paper, we develop an empirical model of an agro-pastoral system subject to high climatic risk to test the impact of rainfall variability on livestock densities, land allocation patterns and herd mobility observed at the community level. Also, because grazing land is a common-pool resource, we determine the impact of cooperation on these decision variables. To capture different abilities of communities to manage these externalities, we construct indices comprised of factors considered to affect the costliness of achieving successful cooperation found in the collective action literature. We then test hypotheses regarding the impact of rainfall variability and cooperation using data collected in a semi-arid region of Niger. Results indicate that...

Optimising woody-weed control
Provedor de dados: 31
Autores: Zull,   Andrew F.; Cacho,   Oscar J.; Lawes,   Roger A.
Woody weeds pose significant threats to the 12.3 billion dollar Australian grazing industry. These weeds reduce stocking rate, increase mustering effort, and impede cattle access to waterways. Two major concerns of woody-weed management are the high cost of weed management with respect to grazing gross margins, and episodic seedling recruitments due to climatic conditions. This case study uses a Stochastic Dynamic Programming (SDP) model to determine the optimal weed management decisions for chinee apple (Ziziphus mauritiana) in northern Australian rangelands to maximise grazing profits. Weed management techniques investigated include: no-control, burning, poisoning, and mechanical removal (blade ploughing). The model provides clear weed management...

International conference on policy and institutional options for the management of rangelands in dry areas: workshop summary paper
Provedor de dados: 31
Autores: Ngaido,   Tidiane; McCarthy,   Nancy; di Gregorio,   Monica.
The System-wide Program for Collective Action and Property Rights (CAPRi) sponsored an International Conference on Policy and Institutional Options for the Management of Rangelands in Dry Areas, May 7-11, 2001 in Hammamet, Tunisia. The conference focused on institutional aspects of rangeland management and brought together policy makers and researchers from North Africa, Sub-Saharan Africa and West Asia to discuss sustainable rangeland production strategies and livelihood of pastoral communities in dry areas. This conference summary paper contains summaries of the CAPRi sponsored research findings on institutional options for rangeland, policy makers’ interventions and reactions as well as the synthesis of discussion groups. These working groups evaluated...

COOPERATION, COLLECTIVE ACTION AND NATURAL RESOURCES MANAGEMENT IN BURKINA FASO: A METHODOLOGICAL NOTE
Provedor de dados: 31
Autores: McCarthy,   Nancy; Dutilly-Diane,   Celine; Drabo,   Boureima.
This paper presents a detailed description of the applied methodology used to study collective action in natural resource management (NRM). Data were collected in 48 villages in northeastern Burkina Faso, at the community, institutional, household and market levels. The paper first discusses the analytical framework underlying the study of collective action, and then describes in detail the methods used to measure collective action and community-level cooperative capacity, and the determinants of cooperative capacity. We also describe data collection methods as well as potential problems in eliciting unbiased information. The impact of cooperative capacity on a variety of outcomes observed at both the community and household level is then presented in...

Could Payments for environmental services improve rangeland management in Central Asia, West Asia and North Africa?
Provedor de dados: 31
Autores: Dutilly-Diane,   Celine; McCarthy,   Nancy; Turkelboom,   Francis; Bruggeman,   Adriana; Tiedemann,   James; Street,   Kenneth; Serra,   Gianluca.
Although several institutional and management approaches that address the degradation of the rangelands have been tested in the dry areas of Central and West Asia and North Africa (CWANA), impact has been limited. Nonetheless, the development of National Action Plans to combat desertification highlights the interest of governments to tackle this issue. Payment for Environmental Services (PES) may be a viable policy option, though, to date, most PES programs have focused on the management of different resources (forests, watersheds). The purpose of this paper is to examine whether PES could be a viable option to promote sustainable rangelands management in the dry rangelands of CWANA. Specifically, it focuses on the scientific gaps and knowledge related to...
