This book was released on 1980 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economy responses to honey mesquite control were estimated for each of the major land resouce regions in Texas. The results pertain to individual ranch firms, and cannot be extrapolated to the total industry without ascertaining the impact of potential supply/demand shifts on cattle prices. The economic analysis utilized a net present value and capital budgeting techniques for a 20-year planning period to estimate annual rate of return (internal rate of return), net present value for a 9 percent discount rate, and net cash flow for alternative mesquite control practices. Net cash flows were expressed in constant 1978 dollars and were developed for alternative weaned beef price scenarios of 34 cents to 54 cents per pound over the 20-year planning horizon. Economic results varied considerably among and within vegetation regions. The variation was a function of range site potential, degree of honey mesquite infestation at the time of treatment, and the control alternative selected. Aerial application of 2,4,5-T consistently produced the highest annual rates of return, regardless of vegetation region. Based on the highest rates of return from each vegetation region, the unweighted average annual rate for return was 15.9 percent. When 2,4,5-T was eliminated as potential control measure, dicamba produced the highest annual rate of return (11.4 percent), approximately one-third less than that from 2,4,5-T. The simple average of the highest average annual rate of return from each resouce region for non-herbicide treatments was 5.7 percent, the average cost of mechanical methods, based on 1978 dollas, would have to be reduced by approximately 50 percent to generate a 9 percent annual rate of return. Assuming long term rainfall patterns and average cattle prices, the average length of time required to recover all investment capital for treatment and additional livestock with 2,4,5-T (8.5 years) was about half that for the "nest-best" herbicide treatment (16 years). Averaged (unweighted) across all resouce regions, the net annual cash flows increased 2.25 dollars per acre from the "next best" non-herbicide alternative. However, it was not possible to identify any single "best" honey mesquite control practices since producer preference is a critical criterion for treatment selection. While aerial application of 2,4,5-T produced the highest annual rates of return, a producer could logically select another practice if it met his minimum rate of return criterion, capital was not limiting, and the prectice higher annual net cash flows than 2,4,5-T. Selection of a practice other than aerial application of 2,4,5-T necessitates greater investment capital requirements. Ranchers typically have pay-back periods which are shorter than pay out periods for brush control. Consequently, as investment capital requirements increase, pay out periods increase, thereby increasing cash flow deficits. Such situations require a transfer of cash from other sources to meet these deficits. Small producers (93 percent of all Texas ranch producers have 200 or fewer cows) have fewer cash sources (because of cash consumption requirements within the ranch firm) to offset an incresing cash flow deficit than do larger producers. No industry supply shifts were evaluated in this study. However, it can be anticipated that if brush management becomes more expensive, fewer acres will be treated. Over time, this could result in a reduction in the supply of beef which will cause prices to increase. The net result on beef prices will depend on the nature of the supply shift relative to demand characteristics for beef.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.
