Land evaluation is the assessment of the suitability of land for a defined land uses. According to FAO (1995) Land can be defined as a delineable area of the earth's terrestrial surface, which encompasses all features of the biosphere immediately or beneath this surface; including those of the near surface- climate, soil and terrain forms; the surface hydrology which comprises shallow lakes, rivers, marshes swamps and etc.; near-surface sedimentary layers and associated groundwater reserve; the animal and plant populations; the human settlements and the physical outcomes of past and present human activities (terracing, water storage or drainage structures, roads, buildings. etc.).
However, Land evaluation is concerned with the process of assessing

Land suitability is assessed and classified with respect to specified kinds of use: This principle is the most essential one of suitability evaluation. It embodies a recognition of the fact that each kind of land use has different requirements. As an example, an alluvial flood plain with impeded drainage might be highly suitable for cultivating rice plant, but not suitable for various forms of agriculture or for forestry. The concept of land suitability is only meaningful in terms of specific kinds of land use, each with their own requirements, e.g. for soil moisture, rooting depth etc. Each type of land qualities such as moisture availability or drainage condition is compared with each kind of land use requirements. Therefore, the land itself and the land use are similarly important to the evaluation of land suitability. ii. The evaluation requires a comparison of the benefits obtained and the inputs needed for different types of land: Land in itself, without input, rarely if ever possesses the productive potential; even the collection of wild fruits requires labour, whilst the use of natural wilderness for nature conservation requires measures for its protection. Assessment of Suitability for each use is made by comparing the required input, such as labour or fertilizer, with the goods produced or other profits …show more content…
Evaluation is made in terms relevant to the physical, economic and social context of the concerned area: in any way, the context within which evaluation takes place is formed by such factors as the regional climate, the living standards of the population, availability and cost of labour, need for employment, the local or export markets, land tenure systems which are socially and politically acceptable, and capital availability. It would, for example, be unrealistic to say that the land was suitable for non-mechanized rice cultivation, requiring large amounts of low-cost labour, in a country with high labour costs. The assumptions underlying evaluation will differ from one country to another and, to some extent, between different zones of the same country. Many of these factors are often implicitly assumed; to avoid misunderstanding and to assist in comparisons between different areas, such assumptions should explicitly be stated.
v. Suitability refers to use on a sustained basis: when making an assessment of the suitability the aspect of environmental degradation should be taken into account. There might, for example, be land use forms which had appeared to be highly profitable in the short run, but were likely to lead to soil erosion, progressive pasture degradation, or adverse changes in river regimes downstream. Such consequences would outweigh the short-term profitability and for this reason the land might be classed as not suitable for such
In order to make the decision, this report measures the following qualitative and quantitative areas:
cost: Measuring the economic value of a service that manpower can build to replace a service that nature provides. Ex: Mangrove Forests; pg. 8. 4th paragraph)
Our system today is inherently opposed to developing a relationship with the land because it depends on evidence in terms of monetary worth. “One basic weakness in a conservationist system based wholly on economic motives is that most members of the land community have no economic value” (246). How much is a wildflower or a songbird worth? Therefore, this infinitely complex ecological system, which depends upon an unforeseeable amount of community-shaping mechanisms, tends to become increasingly diseased. “It tends to ignore, and thus eventually to eliminate, many elements in the land community that lack commercial values, but that are (as we know) essential to its healthy functioning” (252).

Usually, social discount rates are lower than private discount rates because social preferences place greater value on the future generations in contrast with private preferences (Irawan, Tacconi, and Ring 2013). In the Stern Review and the Garnaut Review, the social discount rates were 1 to 2 percent. However, in some REDD+ studies, 10 percent of private discount rate is used (Ebeling and Olander 2011). Therefore, for this study a social discount rate of 3 percent was employed, which is higher than the discount rate used in the Stern and Garnaut Reviews. A positive rate could also be considered to approximate social preferences; one of the most appropriate is the yield of long-term government bonds, which is about 5 percent in case of Peru. In the case of assessment of the value of public investment, discount rates of 9 percent are used, whereas for mitigation projects 3 percent is used and 10 percent for private projects (GIZ 2013). To account for the difference between discount rates in social and business contexts in evaluating land use options, discount rates of 3, 5 and 10 percent were employed. The time considered was 40 years for the forest project in Piura and 30 years for the forest project in the Amazon
“Fat Land”, a book by Greg Cristler, a health journalist who was formerly considered overweight, explains how America became the fattest people in the world. Before writing this book, Cristler was told that he needed to lose forty pounds and so to do so he enlisted a competent doctor, the prescription weight-loss medication Meridia, jogs in a congenial neighborhood park, a wife who cooked him healthy food, and access to plenty of information. Cristler is quick to add that those weren’t the only factors that led to his weight loss, but money and time were a big part of it. Cristler lost the weight, but he states “the more I contemplated my success, the more I came to see it not as a triumph of the will, but as a triumph of my economic and social
The analysis of the Cobb-Douglas function is now extended to include natural resources (R) and land (T).
A land ethic that is governed solely by economic self-interest is not practical in conserving the natural state of the land. This form of conservation is not efficient for the protection of particular elements that make up the ecosystem, due to their lack of commercial value. Each layer that makes up the ecosystem relies on those both above it and below it for various services, like
The solution found by planners to varied situations in practice very dependent on the certain criteria like social, economic, environmental, and political. The evaluation of a solution on these criteria defines the success of a solution.
The graph shows the results that were expected from the land use questionnaire. In the tables, the trend in the graphs show the total’s and average’s over 147 years.
Land as a resource includes unique fertility and mineral deposits, topography, climate, water and vegetation. Trees grown are not categorized as land because they have been deliberately grown; on the other hand, trees in a natural rainforest are a natural resource and thus classify as land. The reward for letting others use the land is called rent. Labor: In order to produce the things, a human resource must be used. Human resources consist of the productive aid of labor made by individuals who work—for instance, miners, artists, and professional baseball players.
Understanding what is meant by land is relatively simple. This comprises all of the natural resources that a particular producer has at their disposal. Most often this means immediate natural resources, like oil or the property on which the production facility is located. This can also include the water or ocean that is close to the facility. The factor of production called land most often comprises the natural and raw materials which are used in production and are at the disposal of the production facility.(2)
On the one hand, participatory approach to land use planning can provide openings for the decentralized administration of land management and enhance legal protection of local land rights through contributing to formal recognition of existing land tenure systems. According to Chigbu et al, (2015) four functions of land use planning that directly links to tenure security. (1) Its capacity to identify or determine land areas, parcels and uses and users. (2) Its propensity to enable documentation of land areas, parcels, rights, restrictions and responsibilities. (3) The opportunities it provides for stakeholder involvement, compensation of claims and community participation. (4) Its impact on land value, land markets and credit opportunities. On the other hand, land use planning, promoting sustainable natural resource use and environmental management are generally part of the mandate of local governments. And these prerogatives often tend to be weakly developed, both legally and with respect to capacity building and methodology (Hilhorst 2010). Unclear property rights and tenure insecurity are the major constraints to the potential of successful land use planning. According to UN-Habitat (2008, p. 17), poor land use planning associated with insecurity of tenure and incompletely specified land rights leads to problems of air and water-borne pollution from agricultural and industrial land use. Though there is a
The world we live in today is always changing, whether it be technology or the land. As these changes take place, society must adapt to them. Many things begin to change as a result of this and society beings to turn into something completely different. One of the most overlooked changes that takes place is that of the environment and landscape. The landscape is one of the most important parts of our society’s culture and has a great effect on how we live. It seems that nowadays, many individuals are taking advantage of the land and nothing appreciating it for every thing that it is worth. Its true that not everyone is going to look at the environment and landscape in the same way, however that is no excuse to disrespect it. Then again, a whole new argument can start from that, as different individuals are going to have different views on what disrespecting the land. Many positive things have come from taking advantage of the land, and also, there have been many negative things to come as a result of this. It all depends on how you look at it. One thing is for sure though, no matter what the case is, the land and environment we live in plays a huge part in each of our everyday lives.
Economic valuation is an important component of environmental policy, although it is difficult to affix a cost on the environment and ecosystem services, it is a measurement that is relevant to most in society humans. Therefore, economic tools may be useful in reinforcing the importance of maintaining biodiversity and preserving fragile ecosystems.
