application of a dynamic model using agronomic and economic data to evaluate the sustainability of the olive grove Landscape of estepa andalusia spain
Landscape Ecology, 2019Co-Authors: A Rodriguez A Sousa, Jesus M Barandica, J Sanzcanada, Alejandro J ResciaAbstract:Context In the Andalusia region (Spain), olive grove agro-systems cover a wide area, forming social-ecological Landscapes. Recent socioeconomic changes have increased the vulnerability of these Landscapes, resulting in the abandonment and intensification of farms. The provision of the main ecosystem services of these Landscapes have thus been degraded. Objectives To analyse the sustainability of an olive grove social-ecological Landscape in Andalusia. Specifically, to develop a quantitative model proposing Land Planning and management scenarios, considering abandonment, production and economic benefits of olive crops in different conditions of erosion and management. Methods We applied a dynamic model using agronomic and economic data, to evaluate different types of olive management. We considered different levels of erosion, the loss of production related to this erosion, and useful life spans for each type of management. We simulated scenarios for the long-term assessment of dynamics of crops, abandonment rate, production and benefits. Results (a) There was a loss of productive Lands and benefits in the medium term in the more intensive crops. (b) Scenarios that partially incorporated ecological management proved to be more sustainable without economic subsidies. (c) The spatial combination of integrated, intensive and ecological plots was sustainable, and was well balanced from an economic, productive and ecological point of view. Conclusions Scenarios that partially incorporate ecological management allowed the best economic and environmental balance. However, to ensure the sustainability of olive Landscapes, farmers should be financially rewarded for their role in the conservation of ecosystem services through Landscape stewardship and direct environmental payments.

decline of forest structural elements across forest urban interfaces is stronger with high rather than low residential density
Basic and Applied Ecology, 2016Co-Authors: Nelida R Villasenor, David B. Lindenmayer, Wade BlanchardAbstract:Abstract Residential development creates a variety of wildLand–urban interfaces, which in turn, can affect biodiversity to different extents. Yet, the paucity of biodiversity research at wildLand–urban interfaces limits our ability to guide management and conservation Planning. We assessed the effect of residential density on vegetation structure (measured along 50 m transects) across urban–forest interfaces (at 0, 100 and 300 m from the urban boundary into urban and forest cover). We compared five functional forms of the effect of distance to a boundary (no-effect, linear, quadratic, piecewise linear, and categorical distance), which can vary with residential density (high and low) and identified the best models describing the proportional cover of five vegetation variables across urban–forest interfaces. We found the proportional cover of most vegetation structures had a high magnitude of change across forest–urban interfaces of high residential density (towns); whereas smoother transitions were found across forest–urban interfaces of low residential density (rural residential). Town interiors exhibited the lowest estimated proportional cover of structural elements characteristic of forests (95% CI: litter = 0–0.05, understory = 0.01–0.03, projective foliage = 0.04–0.18). In contrast, rural residential interiors retained structural elements typical of forests (95% CI: litter = 0.89–0.99, understory = 0.11–0.27, projective foliage = 0.24–0.6). The proportion of understory in forest decreased with the proximity to an urban boundary, but the rate of decline was higher closer to towns than to rural residential areas. Because fauna heavily relies on vegetation structure, the loss of forest structural elements in towns and adjacent forests highlights the urgent need to plan for biodiversity conservation in these areas. Due to rapid urbanization of forest ecosystems worldwide, we discuss advances in Land Planning and fire risk management that may contribute to the conservation of vegetation structures at wildLand–urban interfaces.

the trajectory of dispersal research in conservation biology systematic review
PLOS ONE, 2014Co-Authors: Don A Driscoll, David B. Lindenmayer, Sam C Banks, Philip S Barton, Karen Ikin, Pia E Lentini, Annabel L Smith, Laurence E Berry, Emma Burns, Amanda B EdworthyAbstract:Dispersal knowledge is essential for conservation management, and demand is growing. But are we accumulating dispersal knowledge at a pace that can meet the demand? To answer this question we tested for changes in dispersal data collection and use over time. Our systematic review of 655 conservation-related publications compared five topics: climate change, habitat restoration, population viability analysis, Land Planning (systematic conservation Planning) and invasive species. We analysed temporal changes in the: (i) questions asked by dispersal-related research; (ii) methods used to study dispersal; (iii) the quality of dispersal data; (iv) extent that dispersal knowledge is lacking, and; (v) likely consequences of limited dispersal knowledge. Research questions have changed little over time; the same problems examined in the 1990s are still being addressed. The most common methods used to study dispersal were occupancy data, expert opinion and modelling, which often provided indirect, low quality information about dispersal. Although use of genetics for estimating dispersal has increased, new ecological and genetic methods for measuring dispersal are not yet widely adopted. Almost half of the papers identified knowledge gaps related to dispersal. Limited dispersal knowledge often made it impossible to discover ecological processes or compromised conservation outcomes. The quality of dispersal data used in climate change research has increased since the 1990s. In comparison, restoration ecology inadequately addresses large-scale process, whilst the gap between knowledge accumulation and growth in applications may be increasing in Land Planning. To overcome apparent stagnation in collection and use of dispersal knowledge, researchers need to: (i) improve the quality of available data using new approaches; (ii) understand the complementarities of different methods and; (iii) define the value of different kinds of dispersal information for supporting management decisions. Ambitious, multi-disciplinary research programs studying many species are critical for advancing dispersal research.

estimation of soil erosion risk within a small mountainous sub watershed in kerala india using revised universal soil loss equation rusle and geo information technology
Geoscience frontiers, 2012Co-Authors: V Prasannakumar, H Vijith, S Abinod, N GeethaAbstract:Abstract A comprehensive methodology that integrates Revised Universal Soil Loss Equation (RUSLE) model and Geographic Information System (GIS) techniques was adopted to determine the soil erosion vulnerability of a forested mountainous sub-watershed in Kerala, India. The spatial pattern of annual soil erosion rate was obtained by integrating geo-environmental variables in a raster based GIS method. GIS data layers including, rainfall erosivity ( R ), soil erodability ( K ), slope length and steepness ( LS ), cover management ( C ) and conservation practice ( P ) factors were computed to determine their effects on average annual soil loss in the area. The resultant map of annual soil erosion shows a maximum soil loss of 17.73 t h -1 y -1 with a close relation to grass Land areas, degraded forests and deciduous forests on the steep side-slopes (with high LS ). The spatial erosion maps generated with RUSLE method and GIS can serve as effective inputs in deriving strategies for Land Planning and management in the environmentally sensitive mountainous areas.
