Building new frontiers: An ecosystemic approach to development, culture, education, environment and quality of life

Quality of life, natural and man-made environments, physical, social and mental well-being are currently undermined by all sorts of hazards and injuries; political, economical, social and cultural disarray normalise atrocious behaviours and violence throughout the world. Considering the multiple problems of difficult settlement or solution in our times, current environmental, social, cultural, educational, political and economic policies and practices are examined in view of new paradigms of growth, power, wealth, work and freedom. A multidimensional ecosystemic approach and planning model for the diagnosis and prognosis of quality of life integrate into a dynamic configuration four dimensions of being-in-the- world (intimate, interactive, social and biophysical), as they induce the events (deficits and assets), cope with consequences (desired or undesired) and reorganise for change, enhancing connexions and sealing ruptures. Development and evaluation of teaching programmes, research projects and public policies benefit from a deep understanding of the events, providing a critical comprehensive four-dimensional framework and planning model for effective and responsible action.education; culture; public policies; environment; ecosystems

Living better in a better world: Guidance and counselling in an ecosystemic model of culture

Diagnosis and prognosis of current problems take into account the connections (assets) and ruptures (deficits) between the different dimensions of being-in-the-world, mutually entangled as donors and recipients: intimate; interactive; social and biophysical. Guidance and counselling consider the complex and dynamic configurations formed by the intertwining of the different dimensions, as they combine to produce the events. Cultural and epistemic backgrounds, subject-object relationships, assumptions and conflicts, are examined by heuristic-hermeneutic processes, as new support structures emerge in the socio-cultural learning niches. Problems related to education, culture, ethics, physical, social and mental well-being, natural and man-made environment are treated as ecosystemic configurations, not as separate objects of separate programmes. Values, goals, and principles are considered in the transition from a non-ecosystemic to an ecosystemic model of culture. The proposal presents not only a descriptive position, but also a normative position, a framework for the development and evaluation of public policies and research and teaching programmes, critically inquiring into the prevailing assumptions of growth, power, wealth, work and freedom.education; culture; environment; ecosystemic; guidance; counselling

Intertemporal and Spatial Location of Disposal Facilities

The optimal capacity and location of a sequence of landfills are studied, and the interactions between both decisions are pointed out. Deciding the capacity of a landfill has some spatial implications, because it effects the feasible region for the rest of the landfills, and some temporal implications because the capacity determines the lifetime of the landfill and hence the instant of time where the next landfills will need to be constructed. Some general mathematical properties of the solution are provided and interpreted from an economic point of view. The resulting problem turns out to be nonconvex and, therefore, it can not be solved by conventional optimization techniques. Some global optimization methods are used to solve the problem in a particular case to illustrate the behavior of the solution depending on the parameter values.Landfilling, Optimal Capacity, Optimal Location, Global Optimization.

OPTIMAL SUBSTITUTION OF RENEWABLE AND NONRENEWABLE NATURAL RESOURCES IN PRODUCTION

A theoretical model is presented in order to study the optimal combination of natural resources, used as inputs, taking into account their natural growth ability and the technical possibilities of input substitution. The model enables us to consider renewable resources, nonrenewable, or both. The relative use of resources evolves through time according to the difference between both resources' natural growth and technological flexibility, as measured by the elasticity of substitution of the production function. Output evolves according to a version of the traditional Keynes-Ramsey rule, where the marginal productivity of capital is substituted by the ''marginal productivity of natural capital'', that is a combination of both resources' marginal growth weighted by each resource return in production.Renewable Resources, Nonrenewable Resources, Production, Optimal Control.

On natural resource substitution

We present a simple dynamic model to get some key insights about the substitution of renewable for nonrenewable resources in production and the consequences for sustainability. We highlight the role of the elasticity of substitution (technological component) to determine the adjustment of every sector as a response to scarcity and growing ability of resources (environmental component). Sometimes, the model predicts a smooth substitution of renewable resources for nonrenewables, but this process could work in the opposite direction if renewable resources are temporarily beyond their maximum sustainable yield, so that their marginal natural growth is negative. If substitution possibilities are high enough, it may be optimal to suspend the extraction of a resource, for example, to allow for regeneration of the biomass. We show analytically that a production process is more likely to be sustainable the more heavily it depends on renewable, rather than nonrenewable resources.Renewable resources, Nonrenewable resources, Production, Optimal control.

A Duality Procedure to Elicit Nonlinear Multiattribute Utility Functions.

The practical implementation of the Multiattribute Utility Theory is limited, partly for the lack of operative methods to elicit the parameters of the Multiattribute Utility Function, particularly when this function is not linear. As a consequence, most studies are restricted to linear specifications, which are easier to estimate and to interpret. We propose an indirect method to elicit the parameters of a nonlinear utility function to be compatible with the actual behaviour of decision makers, rather than with their answers to direct surveys. The idea rests on approaching the parameter estimation problem as a dual of the decision problem and making the observed decisions to be compatible with a rational decision making process.Multiple-Criteria Analysis, Multi-Attribute Utility Function, Simulation, Agriculture.

“The Right to the City” An Ecosystemic Approach to Better Cities, Better Life

Urbanism is a focus on cities and urban areas, their geography, economies, politics, social characteristics, as well as the effects on, and caused by, the built environment; it is linked to various aspects of quality of life: education, culture, justice, labour, environment, health, safety, housing, leisure, transport, consumption. This year, the United Nations proposed the following questions for the citizens of the world: What is the best thing about your city? What's the worst thing about your city? What do you want the authorities to do about it? What can you do about it? It is a clear attempt to foster civic participation and personal engagement, but to make things happen it is necessary to create active socio-cultural niches at many societal levels.Urbanism; politics; education; culture; justice

On the equivalence between compromise programming and the use of composite compromise metrics.

This paper analyzes the relationship between Compromise Programming and a close relative called Composite Programming that is based on the use of composite metrics. More specifically, it focuses on the possibility that the results of Compromise Programming are equivalent to those obtained with a particular case of Composite Programming in which a linear combination between the two bounds of the compromise set is established. Several situations, depending on the number of criteria involved and the mathematical structure of the efficient set, are studied. The most relevant result is obtained when two criteria are involved and the efficient set is continuously differentiable. In this case, it is possible to find a unique equivalent value of the control parameter in Composite Programming for each metric in Compromise Programming. It is remarked that this particular case is very relevant in many economic scenarios. On the other hand, it turns out that the equivalence between both approaches can not be extended to the case with more than two criteria.Compromise programming, composite metric, p-norms, economic optimization.

Efficient Economic and Environmental Policies Combining Multicriteria Techniques and General Equilibrium Modelling.

In this paper we propose an analytical approach to obtain so-called efficient policies in terms of environmental and economic objectives. A policy is said to be efficient if any environmental or economic achievement is obtained with the minimum possible detriment to other relevant objectives. We apply this concept obtain the minimum possible environmental impact for a given growth rate or, symmetrically, the maximum economic growth for a given amount of polluting emissions. We present an application to Spanish economy with 2000 data using a Computable General Equilibrium model. We evaluate the efficiency of the observed policy and give some policy recommendations. Finally, we give an idea about how to enlarge the analysis by including additional objectives.Efficient policies, Computable general equilibrium, multicriteria decision making.
