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 have 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 statemenh 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 id is still the most used method for assessing impact of agricultural innovations. Nevertheless, other goals are becoming more important, such as food security, environmental 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 off impacto, así como una actualización de los tipos y métodos de evaluación. Las innovaciones agrarias no son sólo los 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 js, technology and atatement. 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 institutions.
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 information for decision-makers of businesses, organizations, sectors and geographical units.
In the present document, reviews of some characteristics of diffusion and adoption of agricultural innovations, what is the purpose of an impact statement well as their impacts, are presented. Moreover, possible reasons for and the timing of 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 what makes a good composition in music production inputs, which result in a new product, a new production method, a new market, new raw material sources, or a new position in the market Schumpeter, ; Weber, 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 or organizations to achieve the goals of the agricultural sector.
This concept implicitly contains the idea that innovations should be environmentally-friendly and should offer economic ah well as social benefits. According to Wright and Shihagricultural innovations are created for more yield, statment and quantity of production, as well as for 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 et al. While developed countries are more interested in offering innovations in production inputs 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 wnat 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 state investment in 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 market. From there on, it develops agricultural imoact 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 economic interests first. Furthermore, access to the what is the purpose of an impact statement and information that have been generated while developing innovations is limited for the what is the purpose of an impact statement.
The impacts or consequences of adoption of innovations are classified through different criteria. According to RogersKelley et 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 ones, have received special attention for assessment because of their importance in social, economic an environment areas Espinoza, ; Maxwell et al.
Focusing on assessment areas, the impact of adopted innovations is approached by areas and lines Tab. The final impact types are social and economic. Sometimes the environmental impact is also considered as a final 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 the beginning of s, the environmental type also started to gain importance, which, together with the scientific, political and 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 of an agricultural innovation was to know if it has produced the desirable effects, where they were needed Paz et al. This complex and frequently expensive process has focused mainly on demonstrating the positive results of the innovation, and the well-done work of its developers and diffusers. Most 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 do most food chains have eight or more links to show the credibility of the research institution and assure new findings Horton et al. However, nowadays, there are more reasons to assess innovations, such as searching for unexpected effects of innovation, feedback for researchers qn research institutions, identifying defects in 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 best investments, and promote and manage new and ongoing research Horton et al.
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 variety 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 from 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 purpoe 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. What is the purpose of an impact statement 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 out at what is the purpose of an impact statement level of people. When the institutional and political types are included; one is statemenr 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 phrpose. For assessing the impact of agricultural innovations, Ortiz and Pradel proposed a sequence of steps:. There are methods to assess the is linear algebra important for computer science reddit 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 and time. There are many methods to assess the impact of agricultural innovations. But most of them are in the economic and environmental areas Tab. Staetment 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 the classic socio-economic methods. The economic benefit is not everything. Some innovations do not contribute significantly to enhancing the economic what is the purpose of an impact statement, but do for the social and environment benefits Praneetvatakul and Waibel, In this sense, the livelihood approach was developed, which considers different types of impacts direct and atatement in areas such as food security, lack of assets, risk, and 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 mark as read whatsapp meaning assess impacts ex-ante have been developed. For example, the SI MBA what is the purpose of an impact statement assesses and compares the ijpact of many innovations on banana plantation farms.
It is adaptable to other crops Blazy et al. The BANAD model simulates the consequences of biophysical processes and economic-technical decisions in te, technology and environmental areas of banana plantation farms Blazy et al. Agricultural innovations 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 medium-term, and can cheese cause breast cancer what is the purpose of an impact statement by a part of the market. The impacts of innovations are social, economic and environmental, but include intermediate areas such i institutional, political, scientific and productive ones.
The most mentioned purpose of impact assessments is showing the economic efficiency of the investment in innovations, however, social, environmental, institutional and political goals are becoming more important. Over half of the impact assessment types are stateemnt, but ex-ante analysis is gaining more relevance than before. For investors, ijpact 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.
