Supporting conservation with biodiversity research in sub-Saharan Africa’s human-modified landscapes

Journal Articles & Books
Diciembre, 2014
África

Protected areas (PAs) cover 12� % of terrestrial sub-Saharan Africa. However, given the inherent inadequacies of these PAs to cater for all species in conjunction with the effects of climate change and human pressures on PAs, the future of biodiversity depends heavily on the 88� % of land that is unprotected. The study of biodiversity patterns and the processes that maintain them in human-modified landscapes can provide a valuable evidence base to support science-based policy-making that seeks to make land outside of PAs as amenable as possible for biodiversity persistence.

Adaptive landscape modernization of forest and hydraulic ameliorative land management in the Volga region

Journal Articles & Books
Diciembre, 2012

An analysis of adaptive landscape amelioration of lands with a geomorphologic classification of characteristic types of agrolandscapes is given. Control of drought and soil-destroying processes is based on a systems approach, including organizational-economic and agro-, phyto-, forest, and hydraulic amelioration measures. The system of ameliorative procedures takes into account the ecological ameliorative requirements and limitations with the developed criteria and standardized evaluation parameters of soils and waters when realizing the concept of adaptive landscape management.

Managing for rainfall variability: effect of grazing strategy on cattle production in a dry tropical savanna

Journal Articles & Books
Diciembre, 2009
Australia

Rainfall variability is a challenge to sustainable and profitable cattle production in northern Australia. Strategies recommended to manage for rainfall variability, like light or variable stocking, are not widely adopted. This is due partly to the perception that sustainability and profitability are incompatible. A large, long-term grazing trial was initiated in 1997 in north Queensland, Australia, to test the effect of different grazing strategies on cattle production.

Archaeological Analysis of Bison Jumps and the Implications to the Contemporary Management of Bison Herds on the North American Great Plains

América Septentrional

The National Park Service (NPS) and other land management agencies have interest in managing bison herds under “natural” conditions; yet demographic features of natural populations are not well described. One solution to this issue involves the analysis of historical bison (Bison spp.) jump data. We conducted a literature search of archeological data associated with bison jump sites in North America with the goal of analyzing the data and summarizing historical bison demographics. We identified six locations with adequate information to conduct vertical life-table analyses.

Paddock to reef monitoring and modelling framework for the Great Barrier Reef: Paddock and catchment component

Journal Articles & Books
Diciembre, 2012

Targets for improvements in water quality entering the Great Barrier Reef (GBR) have been set through the Reef Water Quality Protection Plan (Reef Plan). To measure and report on progress towards the targets set a program has been established that combines monitoring and modelling at paddock through to catchment and reef scales; the Paddock to Reef Integrated Monitoring, Modelling and Reporting Program (Paddock to Reef Program). This program aims to provide evidence of links between land management activities, water quality and reef health.

Analytical assessment of sustainable development concept

Policy Papers & Briefs
Diciembre, 2012
Letonia

Generally, sustainability dimension is related to a context, timing and scale. Although the context of sustainability can be various – either general or more specific, the timing is oriented to the long-term, but the scale has a global nature. The main purpose of the paper is to assess analytically the sustainable development concept.

Modeling vegetation heights from high resolution stereo aerial photography: An application for broad-scale rangeland monitoring

Journal Articles & Books
Diciembre, 2014

Vertical vegetation structure in rangeland ecosystems can be a valuable indicator for monitoring rangeland health or progress toward management objectives because of its importance for assessing riparian areas, post-fire recovery, wind erosion, and wildlife habitat. Federal land management agencies are directed to monitor and manage rangelands at landscapes scales, but traditional field methods for measuring vegetation heights are often too costly and time consuming to apply at these broad scales.

Precision, Repeatability, and Efficiency of Two Canopy-Cover Estimate Methods in Northern Great Plains Vegetation

Journal Articles & Books
Diciembre, 2008

Government agencies are subject to increasing public scrutiny of land management practices. Consequently, rigorous, yet efficient, monitoring protocols are needed to provide defensible quantitative data on the status and trends of rangeland vegetation. Rigor requires precise, repeatable measures, whereas efficiency requires the greatest possible information content for the amount of resources spent acquiring the information. We compared two methods--point frequency and visual estimate--of measuring canopy cover of individual plant species and groups of species (forbs vs.

Post‐fire habitat use of the golden‐backed tree‐rat (Mesembriomys macrurus) in the northwest Kimberley, Western Australia

Journal Articles & Books
Diciembre, 2015

Fire regimes are changing throughout the world. Changed fire patterns across northern Australian savannas have been proposed as a factor contributing to recent declines of small‐ and medium‐sized mammals. Despite this, few studies have examined the mechanisms that underpin how species use habitat in fire‐affected landscapes. We determined the habitats and resources important to the declining golden‐backed tree‐rat (Mesembriomys macrurus) in landscapes partially burnt by recent intense fire.

Livestock water productivity: implications for sub-Saharan Africa

Journal Articles & Books
Diciembre, 2009
África

Water is essential for agriculture including livestock. Given increasing global concern that access to agricultural water will constrain food production and that livestock production uses and degrades too much water, there is compelling need for better understanding of the nature of livestock-water interactions. Inappropriate animal management along with poor cropping practices often contributes to widespread and severe depletion, degradation and contamination of water.
