Available in PDF, EPUB and Kindle. Book excerpt: Three basic model of soil conservation decisions are developed with a complete analysis of their dynamic properties. The first model assumes that soil is farmers' main asset and that they recognize its influence on the production function and the effects of agricultura production on the soil. The model indicates that the steady state shadow price of the soil characteristic will increase whenever output price increases or the discount rate decreases,while a higher discount rate or soil renovation rate will lower it. The effects of these parameters on the steady state soil stock will be opposite to those on its shadow price, but an increase in the discount rate would lower both. The effects of input price changes can be signed with few additional assumptions. The monotonicity property of the solution is derived and commented upon. An expanded version of the above model is analized in chapter four, to study the case when farmers also accumulate capital and financial assets. Contrary to what would be expected, most of the steady state comparative statistics results can be signed when capital and soil stock are assumed to be complements. In this model there possibility of having increases in steady state soil stock with an increase in the interest rate. The monotonicity property of the optimal solution is maintained given the stability properties of the solution. The final chapter presents two related dynamic stochastic models of farmer's decisions to study the effects of wealth and revenue variability. The two-date.

Download or read book Land And Soil Management written by Alfredo Sfeir-Younis and published by CRC Press. This book was released on 2019-04-11 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil erosion has become a problem of crisis proportions in developing countries around the globe, and better approaches to land management are desperately needed. This book provides analytical frameworks to guide the creation and appraisal of soil erosion control programs. The authors discuss a broad range of important issues involved in designing and implementing more effective soil conservation programs. The book begins with a discussion of the physical and economic dimensions of soil erosion and an estimation of the extent of the problem. It then explains how to improve the evaluation of soil conservation programs by integrating scientific knowledge with economic methods and procedures. A series of practical illustrations graphically demonstrates the application of the concepts derived from the theory. The most important organizational, institutional, technical, and macroeconomic aspects of soil and land management appraisal are outlined, and the major elements of project or program design are also pinpointed and illustrated. Finally, the book suggests areas most in need of future research.
Download or read book Foundations of Dynamic Economic Analysis written by Michael R. Caputo and published by Cambridge University Press. This book was released on 2005-01-10 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foundations of Dynamic Economic Analysis presents a modern and thorough exposition of the fundamental mathematical formalism used to study optimal control theory, i.e., continuous time dynamic economic processes, and to interpret dynamic economic behavior. The style of presentation, with its continual emphasis on the economic interpretation of mathematics and models, distinguishes it from several other excellent texts on the subject. This approach is aided dramatically by introducing the dynamic envelope theorem and the method of comparative dynamics early in the exposition. Accordingly, motivated and economically revealing proofs of the transversality conditions come about by use of the dynamic envelope theorem. Furthermore, such sequencing of the material naturally leads to the development of the primal-dual method of comparative dynamics and dynamic duality theory, two modern approaches used to tease out the empirical content of optimal control models. The stylistic approach ultimately draws attention to the empirical richness of optimal control theory, a feature missing in virtually all other textbooks of this type.

This book was released on 2001 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study examines the current and potential role of economics in soil productivity in sub-Saharan Africa. After examining the status of soil productivity and the contribution of conventional economic analyses, it considers more innovative approaches that enable economics to play a greater role in the planning and evaluation of soil productivity, enhancing measures at farm, national and global level. In the past economics has tended to focus on one factor at a time but many factors affect soil productivity. Decisions, policies and their impact call for a more integrative, participatory analytical approaches capable of weighing various aspects simultaneously. This study highlights how economics can respond to this challenge through the a[application of fresh concepts (e.g. natural capital) and specific techniques (e.g. multi-criteria analysis, green accounting).
Download or read book Economics of Land Degradation and Improvement A Global Assessment for Sustainable Development written by Ephraim Nkonya and published by Springer. This book was released on 2015-11-11 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume deals with land degradation, which is occurring in almost all terrestrial biomes and agro-ecologies, in both low and high income countries and is stretching to about 30% of the total global land area. About three billion people reside in these degraded lands. However, the impact of land degradation is especially severe on livelihoods of the poor who heavily depend on natural resources. The annual global cost of land degradation due to land use and cover change (LUCC) and lower cropland and rangeland productivity is estimated to be about 300 billion USD. Sub-Saharan Africa (SSA) accounts for the largest share (22%) of the total global cost of land degradation. Only about 38% of the cost of land degradation due to LUCC - which accounts for 78% of the US$300 billion loss – is borne by land users and the remaining share (62%) is borne by consumers of ecosystem services off the farm. The results in this volume indicate that reversing land degradation trends makes both economic sense, and has multiple social and environmental benefits. On average, one US dollar investment into restoration of degraded land returns five US dollars. The findings of the country case studies call for increased investments into the rehabilitation and restoration of degraded lands, including through such institutional and policy measures as strengthening community participation for sustainable land management, enhancing government effectiveness and rule of law, improving access to markets and rural services, and securing land tenure. The assessment in this volume has been conducted at a time when there is an elevated interest in private land investments and when global efforts to achieve sustainable development objectives have intensified. In this regard, the results of this volume can contribute significantly to the ongoing policy debate and efforts to design strategies for achieving sustainable development goals and related efforts to address land degradation and halt biodiversity loss.
