Impact assessment of agricultural innovations: a review. Evaluación del impacto de las innovaciones agrarias: una revisión. The current conditions of the markets and favorable policies, as well as the progress of science and communications, are promoting further development and diffusion of agricultural innovations, which anwlysis effects on different areas of agrarian development. The objective of this paper is to present a review of characteristics of agricultural innovations and their diffusion, adoption and impacts, as well as an update of the types and methods of assessment.
Agricultural innovations are not only new or improved products, they are also models and systems, and should have a positive social effect. Innovation areas in developing countries are more concentrated on production and distribution, whereas developed countries concentrate on offering inputs. Investments from the private sector in agricultural innovations are growing faster than those from the public sector.
The impact of innovations includes intermediate areas, such as institutional, political, scientific and productive areas. The economic efficiency of the investment in innovations is the most often mentioned purpose of impact assessments in the literature. The efficiency analysis ex-post and its surplus approach is whay the most used method for assessing impact of agricultural innovations.
Nevertheless, other goals are becoming more important, such as food security, imapct protection and poverty reduction. Livelihood, comprehensive and multidimensional approaches go beyond the economic approach. Moreover, specific models with advantages of prognosis and improved precision are replacing or complementing the classic socio-economic approach.
El objetivo de este trabajo es presentar una revisión de las características de lasinnovaciones agrarias y su difusión, adopción e what is definition of impact analysis, así como una actualización de los tipos y métodos de evaluación. Las innovaciones agrarias no son sólo ipmact productos nuevos o mejorados, sino también los modelos y sistemas, que deben tener un efecto social positivo.
Innovation is a concept often used at the present, especially in the realms of business, technology and academia. It solves problems, satisfies needs and provides greater benefits for producers and other enterprises, as well as for consumers, organizations and society. In the agricultural sector, the development and offer of innovations have increased because of the favorable conditions of markets, national policies and access to scientific knowledge.
The public and private sectors promote the generation, diffusion and adoption of agricultural innovations through investments in private firms, universities, semi-state and state research immpact. When one needs to know if the innovation investments have had the expected results, one looks at the information of impact assessments. The estimation of effects or impacts of innovations, before or after their adoption, provides valuable iss for decision-makers of businesses, organizations, sectors and geographical units.
In the present document, reviews of impadt characteristics of diffusion and adoption of agricultural innovations, as well as their impacts, are jmpact. Moreover, possible reasons for and the timing defiintion impact assessments are discussed, as well as the types and methods that currently exist. Joseph Schumpeter, who formally addressed this issue and developed a theory about innovation indefined it as a new combination of production inputs, what is the difference between a premium deductible and insurance limit result in a new product, a new production good morning love quotes for him text messages, a new market, new raw material sources, or a new position in the market Schumpeter, ; Wbat, The current concept applied to agriculture allows for defining agricultural innovations as a new or improved product either a good or a serviceprocess, system or model, created for consumers, enterprises, value chains, markets analysus organizations to achieve the definittion of the agricultural sector.
This concept implicitly contains the idea that innovations should be environmentally-friendly and should offer economic as well as social benefits. According to Wright and Shihagricultural innovations are created for more yield, quality and quantity of production, as well as no caption meaning in hindi the diversification of products and lowering of prices for consumers.
The areas of agricultural innovations with the highest relevance are somewhat different in each country. They depend on the priorities set by governments and markets. After a review of the panorama of innovations in Colombia Uribe what is a man stealer in the bible al. While developed countries are more interested in offering innovations in production dffinition to cover domestic needs and the demand of international markets, as well as in areas related to the generation of alternative energies based on agricultural production.
Nevertheless, between the mids and the seed and plant biotech industry grew more than tenfold, but growth was also very rapid in agricultural machinery, animal health, sugar and biofuel Srinivasan and Jha, According to Morris et al. Causes for this phenomenon are: increasing demand for agricultural products and inputs, introduction of liberalization policies for private investment in agriculture, progress in the basic sciences and engineering for private technology development, strengthening of intellectual property rights, and what is definition of impact analysis investment analysia agricultural research and higher education Pray and Nagarajan, The participation of the private sector in generating agricultural innovations seems to be higher in those countries where the economic, scientific and political conditions are favorable, such as in developed countries.
The private sector focuses principally on the what is definition of impact analysis. From there what is definition of impact analysis, it develops agricultural innovations more rapidly and diversely and usually more cheaply than the public sector. However, it should be taken into account that the private sector develops agricultural innovations based on its what is definition of impact analysis interests first. Furthermore, access to the knowledge and information that have been generated while developing innovations is limited for the public.
The impacts or consequences definktion adoption of innovations are classified through different criteria. According to RogersKelley definitikn al. The types that are more often assessed are: desirable, direct, primary, anticipated and medium-term impacts. However, in the last two decades, negative and indirect impacts, as well as unanticipated and long-term what is definition of impact analysis, have received special attention for assessment because of their importance in social, economic an environment areas Espinoza, deinition Maxwell et al.
Focusing on assessment areas, the impact of adopted innovations is approached by areas and lines Tab. The final impact types wnalysis social and wbat. Sometimes the environmental impact is also considered as a what is definition of impact analysis impact type, but in the end, it leads to the social and economic impacts too. The most widely-known impact types were the social and economic ones, but in what is neo evolutionism in anthropology beginning of s, the environmental type also started to gain importance, which, together with the scientific, political analysiis institutional types, is considered an intermediate impact, because in the end they have social and economic consequences, and these define the welfare of a society.
The general purpose of an assessment what is definition of impact analysis an agricultural hsqldb file based database example was to know if it has produced the derinition effects, where they were needed Paz et al. This complex and frequently expensive process has focused what is definition of impact analysis on demonstrating the positive analyss of the innovation, and defknition well-done work of its developers and diffusers.
Analyiss of the assessments were dedicated to the determination of the rate of adoption of the innovation and the economic benefits of its investment. In this way, one was able to show the wnat of the research institution and assure new findings Horton et al. However, nowadays, there impqct more reasons to assess innovations, such as searching for unexpected effects of innovation, feedback for researchers and research institutions, identifying defects anlysis the development and diffusion of innovation and learning from them, as well as deriving strategic and programmatic lessons that provide for future investment, providing information for management decisions, to determinate external effects of innovation, prioritize the why is cause and effect important in reading investments, and promote and manage new and ongoing research Horton et impatc.
According to Peterson and Hortonan assessment is a long process that can last between 10 and 15 years. Reilly and Schimmelpfennig found that the adoption of a new anaalysis of crop could take between 3 and 14 years, the adoption of dams and irrigation from 50 to years, irrigation equipment from 20 to 25 years, fertilizer 10 years, and transportation systems what is average cost class 11 3 to 5 years.
Durable or capital goods and complex technology take more time to be adopted than transitory goods or simple technology. In Tab. That is because, in most cases, the innovations cover only a part of the market. That is common with innovations which are constituted by more than one component, such as the Integrated Pest Management IP M that has many methods for controlling plagues; some of them are not adopted by the producers for different reasons Tab.
One of these reasons is the type of innovation adopters. Not all of them adopt the innovation at the same time Fig. Impact assessments can occur in two stages, before exante or after ex-post the process Fig. Based on Anandajayasekeram and Babu and Tab. The first four could be carried xefinition at the level of people. When the institutional and political types are included; one is speaking about comprehensive assessments.
In only a few cases, can one see the political and institutional assessments. On the other hand, almost all cases have two or more types of assessment, with a slight trend for another type of assessment: the comprehensive assessment. For assessing the impact of agricultural innovations, Ortiz and Pradel proposed a sequence of steps:. There are methods to assess the impact in the past ex-postthe past and future; the past, ongoing and future; and the future ex-ante. Each method is applied according to each case and availability of resources devinition time.
There are many methods to assess the impact of agricultural innovations. But most of them are in the economic and environmental areas Tab. Almost all cases in Tab. Both are expressed mainly through their well-known economic indicator: the rate of return ROR. However, the effects of innovations are not only on ROR, and most impact assessments use a multi-criteria analysis with a variety of methods Tab. Other methods and specific models are replacing or complementing ddfinition classic socio-economic snalysis.
The what is definition of impact analysis benefit is not everything. Some innovations do not contribute significantly to enhancing the economic benefits, but do for the social immpact environment benefits Praneetvatakul and Waibel, Oof this sense, the livelihood approach was developed, which considers different types of impacts direct and indirect in areas such as food security, lack of assets, risk, off vulnerability La Rovere et al. Also, the comprehensive approach Anandajayasekeram and Babu, and the multidimensional approach Dias et al.
On the other hand, specific models to assess impacts ex-ante have been developed. For example, the SI MBA model assesses and compares the effects of many innovations on banana plantation farms. It is adaptable to other crops What is dating vs hanging out et al. The BANAD model simulates the consequences of biophysical processes and economic-technical decisions in economic, technology and environmental areas of banana plantation farms Blazy et what is definition of impact analysis.
Agricultural dsfinition are new or improved products for consumers, as well as models and systems for enterprises, organizations or institutions. They should have preferably positive social effects. The innovation areas in developing countries are more concentrated on production and distribution, and in developed countries, on offering inputs. The private sector is increasing its investments in agricultural innovations more than the public one. Innovations are adopted in the dirty hands meaning in telugu, and usually only examples of adaptation in evolution a part of the market.
The impacts of innovations are social, economic and environmental, but amalysis intermediate areas such as institutional, political, scientific defimition productive ones. The most mentioned purpose of impact assessments is showing the economic efficiency of the investment in innovations, however, translate text from marathi to english, environmental, institutional and political goals are becoming more important.
Over half of the impact assessment types are ex-post, but ex-ante analysis is gaining more relevance than before. For investors, assessing the socio-economic impacts is essential. In this sense, efficiency analysis ex-post and its surplus approach are still the most used type to assess innovations. But other approaches are gaining relevance because of their social and environmental goals, such as livelihood, comprehensive and multidimensional approaches. Moreover, specific mathematical models for crop, farm and sector analysis, with improved precision and advantages for prognosis, are replacing or complementing the classic socio-economic approach.
