The world’s population and food consumption are increasing drastically while natural resources are decreasing. In particular, energy use is an important component of reaching sustainability in agricultural production processes because of its shortage as resource, its influence on air pollution and its role in the economics of production. This study used system modeling to examine interactions between crop and livestock procedures and between levels of different input factors and their effects on yields in order to determine agricultural energy intensity.

Enset (Ensete ventricosum) production is declining, and it faces genetic erosion due to drought, diseases and population pressure. Participatory Rural Appraisal (PRA) and additional formal survey studies on 315 households were conducted over three consecutive years (1998–2000) in the Sidama, Wolaita and Hadiya ethnic regions of southern Ethiopia to assess traditional cultivation methods, analyse the production systems, and evaluate farm-based enset biodiversity. The regions differ in terms of cultural background, resources, farming systems, population density, and agro-ecology.

This paper presents a case study of land-use/land-cover (LULC) changes from 1975 to 2014 in the central highlands of Ethiopia and traces out its impact on socioeconomic conditions of the local community in the study area. We used four time series Landsat satellite images, that is, Landsat MSS (1975), Landsat Thematic Mapper (1986), Enhanced Thematic Mapper (2000), and Landsat 8 OLI scenes (2014), to investigate the changes in LULC.

During the past two decades or so, rural population in Africa has increased slowly while urban population has grown dramatically. The hugely increased urban demand for cereals and pulses (which produce crop residues for livestock) and for livestock products is now the main force stimulating mixed farming systems in the semiarid and subhumid areas of subSaharan Africa. Grazing land has diminished, crop residues are becoming a more important element in raising livestock and fattening penned livestock has become profitable.

The paper deals with the relationships between the intra-familial dimensions of land rights and the productive use of resources. Analysis is carried out along two axes. We first show how the distribution of rights within families influences the productive use of land. We then explain how the evolution in production opportunities is influencing the organisation of intra-family land rights.

The multifunctionality of agriculture promoted by the Agriculture Act is difficult to reconcile with the intensive models dominant in Guadeloupe and Reunion. This is made clear by an analysis of the management rules and practices for territorial farming contracts, intended to implement this Act. The difficulty of this reconciliation can also be observed by the impact that the statute’s application has had on its targets — production units. We conducted open or conversation interviews with institutional personnel and with farmers who have signed these contracts.

Should farming and conservation policies aim broadly to separate land for nature and land for production (land sparing) or integrate production and conservation on the same land (wildlife-friendly farming)? Most studies that try to address this question suffer from flaws in sampling design, inappropriate metrics, and/or failure to measure biodiversity baselines. We discuss how these failings can be addressed, and what existing information tells us about the key debates on this topic. The evidence available suggests that trade-offs between biodiversity and yield are prevalent.

Making the assumption that property rights might determine whether farmers adopt particular strategies, this study aims at modelling farmers’ decisions to adapt to climate change by focusing on their property rights – declined as institutional arrangements on land and rights on land – as well as their socio-economic and demographic characteristics. The case study took place in northern Benin (West Africa). In this zone, 308 farmers producing maize and adapting to climate change were randomly sampled.

Yak farming is the main livelihood source for the high altitude communities in the eastern Himalaya. With increasing access to modern facilities, market opportunities and changes in the legal framework, pastoral systems in the Himalaya are undergoing an unprecedented change. Questionnaire-based qualitative surveys were conducted in five villages of northern Bhutan, to understand how the recent changes in the legal framework for Cordyceps (known as caterpillar fungus) collection have caused specific changes in yak farming practices.

This article examines the process of agroecological research on beekeeping systems, developed jointly by the Temperate Agriculture Program of the Brazilian Agricultural Research Company (EMBRAPA), and the Institute of Sociology and Peasant Studies (ISEC), of the University of Córdoba. The investigation was carried out on different beekeeping experiences in southern Brazil: peasant family farms, settlements of agrarian reform, and Afro-descent quilombola and Guarani indigenous villages.

There is a strong need for accurate and spatially referenced information regarding policy making and model linkage. This need has been expressed by land users, and policy and decision makers in order to estimate both spatially and locally the impacts of European policy (like the Common Agricultural Policy) and/or global changes on farm-groups. These entities are defined according to variables such as altitude, economic size and type of farming (referring to land uses).
