“…This specialization has repercussions on the territorial dynamic of the Pampa region (Albaladejo 2011); in particular, there is an increasing migration from the countryside towards the cities and local farming know-how that has not been written down is being lost (Hernández 2009). The development of monocultures or quasi-monocultures generates a homogenization of landscape mosaics, with implications for the ecosystem services related to biodiversity (Benton et al 2003;Barral and Maceira 2012) and encouraging an increase in health risks at territory level. These simplified practices involve the repeated use of glyphosate, which can build up tolerance in some weeds (Avena fatua, Sorghum Halepense), causing the producer to resort to the use of even more herbicides.…”

Farming activities in the Argentinean Pampa have focused on soybean production since the 1990s. The resulting cropping systems may not be sustainable in the long run due to development of glyphosate-tolerant weeds, homogenization of landscape mosaics, and pollutions. Here, we used the tracking on-farm innovation method to produce resources for the design of alternatives. The five steps of tracking on-farm innovation were (1) characterization of the soybean-based dominant cropping system, (2) identification of producers developing alternative systems, (3) description of these cropping systems and their agronomic logic, which is the link between the producer practices and their motives when choosing these practices, (4) multicriteria assessment of the performances of the systems, and (5) analysis of the development conditions of the most efficient systems. We identified 22 alternative cropping systems developed by farmers. These systems all include original practices: diversification of crop rotations (22 cases), occasional return to tillage (15 cases), and low pesticide use (16 cases). Some alternative systems were more sustainable than the soybean-based system, as shown by lower economic risk level, better ability to maintain soil organic carbon content, and less glyphosate-tolerant weeds. Our results show overall that tracking on-farm innovations is an efficient method to get references on alternative cropping systems developed by farmers.

“…En Argentina, el ordenamiento territorial y el observatorio ambiental son dos instrumentos de políticas públicas de implementación reciente (MAGyP 2012). Dentro de estos marcos, en los que las decisiones de conservación o restauración de los ecosistemas naturales presentan cierta urgencia, la consulta a expertos es una estrategia rápida y eficiente para contar con información de calidad sobre un tema específico (Sutherland 2006;Kuhnert et al 2010;Martin et al 2012;Barral and Maceira 2012). A su vez, existen diversas herramientas que permiten diagnosticar el estado de conservación de un ecosistema brindando apoyo valioso para la toma de decisiones sobre el monitoreo ecológico.…”

R��. Los bordes de caminos rurales (BCR) son elementos clave para conservar la biodiversidad y los servicios ecosistémicos en los paisajes agrícolas. Su restauración y manejo requieren de protocolos sencillos que valoren (diagnostiquen) su estado de conservación y funcionalidad ecológica. En este trabajo elaboramos un índice del valor de conservación (IVC) de los BCR por medio de la construcción de un árbol de decisiones realizado a partir de la consulta a expertos. El índice, que puede asumir valores entre 4 y 30, evalúa el estado de conservación y la funcionalidad ecológica de los BCR según 11 atributos relacionados principalmente con la estructura de la vegetación. El IVC fue aplicado a 30 BCR del sudeste bonaerense (Argentina). Sus valores oscilaron entre 4 y 29. Los BCR cultivados fueron los de menor valor. Los BCR con IVC más alto (>21) se caracterizaron por la mayor riqueza de especies nativas, entomófilas y de valor cultural, la mayor cobertura de especies nativas y pastos perennes, la menor cobertura de malezas y especies invasoras, y la presencia de al menos una especie vulnerable y/o fitotelmata. Este índice representa una primera contribución aplicable al diagnóstico del estado de conservación de los BCR a través de la identificación de atributos claves de la estructura de la vegetación sugeridos por expertos. Además, el índice provee información relativamente sintética sobre el estado de los BCR, los que, pese a sus múltiples funciones ecológicas, rara vez son tenidos en cuenta para su conservación dentro de la planificación territorial.[Palabras clave: biodiversidad, corredores, elementos lineales del paisaje, pastizales remanentes, consulta a expertos, árbol de decisiones] A��. A proposal to assess the conservation status of roadsides in southeastern Buenos Aires. Rural roadsides (RRS) are key elements for conserving biodiversity and ecosystem services in agricultural landscapes. Their restoration and management require simple protocols to assess (diagnose) their conservation status and ecological functionality. We elaborated a conservation value index (CVI) of RRS by constructing a decision tree based on the experts' opinion. The index, which can range between 4 and 30, evaluates the conservation status and ecological functionality of RRS according to 11 a�ributes related to vegetation structure. The CVI was applied to 30 RRS in southeastern Buenos Aires (Argentina). Values ranged from 4 to 29, being the cropped RRS those with the lowest value. The RRS with the highest CVI (>21) were those characterized by higher richness of native, entomophily and cultural value species, higher coverage of native species and perennial grasses, lower coverage of weeds and invasive species, and presence of at least a vulnerable and/or phytotelmata species. This index represents a first contribution applicable to the diagnosis of the conservation status of RRS through the identification of key a�ributes of vegetation structure suggested by experts. In addition, the index provides relatively synthetic infor...

“…Optimizing cultivated land use benefits is the ultimate goal of achieving cultivated land use with multiple objectives under moderate restructuring of agrarian property regimes [18], which include not only providing food and clothing but also food security, social security and ecosystem sustainability [19][20][21][22]. Most empirical studies assessing cultivated land use benefits and their driving forces have focused on the following research areas on economy, society and ecology: production pattern recognition, social security assessment, and ecological state estimation [23][24][25][26].…”

Abstract:Agrarian property regimes interact with relevant property stakeholders' behaviors and benefits, playing a vital role in national and regional cultivated land use. In China, state and collective agrarian property regimes are the two main forms of cultivated land use. To help fully realize the multi-objectives of cultivated land use benefits provided by agrarian property regimes, our study investigated the relationship between agrarian property regimes and cultivated land use. This paper describes the role of a cultivated land use system in facilitating the relationship between agrarian property regimes and cultivated land use from a geographical perspective. Understanding the cultivated land use system is the foundation for comparatively analyzing differences in the cultivated land use benefits in two adjacent areas, a state-owned regime and a collective regime, in the city of Fujin, China, through a comprehensive evaluation. We found the following results: (1) The arrangement of agrarian property rights directly reflects capital, material and technology inputs by motivating agricultural labors to obtain different economic benefits; (2) The state agrarian property regime reflects top-down agricultural management while the collective agrarian property regime reflects bottom-up agricultural management in China. The different agricultural managements influence planting structure and land use planning, resulting in different ecological benefits; (3) Labor division and social insurance are the main drivers of different social benefits from the two regimes. Examining cultivated land use benefits provides a new comparative perspective for studying agrarian property regimes. The results show that cultivated land use benefits from collective and state agrarian property regimes are different. These findings clarify that, incentivized by the different types of agrarian property ownerships represented by collectively and state-owned regimes, local governments and organizations aim to achieve the multi-objective cultivated land use benefit goal of Chinese agricultural development, including economic, ecological and social benefits. With China's goal of conducting moderate agricultural reform in its agrarian property regime, verification of rural collective land rights is an effective form of asset management in collective areas in China, while deepening land tenure and usufruct is an important priority in state-owned regimes. Furthermore, to make full use of agricultural resources, it is necessary to have a close collaboration between the collective agrarian property regime and the state agrarian property regime.
