Major Transformation

This paper evaluates in a holistic way major trends in US production of food, feed, and biofuel commodities over the period 1961-2014. It is motivated by literature that examines parts of the changes but does not integrate them. We develop a comprehensive data set and then conduct analysis of the major trends that emerge. We identify eight major trends and then combine them to four major themes. The first theme is the huge gain in agricultural productivity over this period. An important component of this theme is that the productivity gain was sufficient to achieve substantial total production growth as agricultural land declined over the period. Second, there has been a major transformation of the livestock sector as less efficient and more expensive beef has been replaced by more efficient and less expensive poultry. As this change has happened, the livestock sector has become more land efficient, less land used in livestock. The third major change is that US calorie production is now substantially more than the needs for food and feed. Finally, the first three major themes have enabled the fourth, which is growth of US renewable fuel production, while agricultural land declined over time.

Sequestration Potential

The vegetation and the afforestation of agricultural land non-forest represent a potential increase in carbon stocks which could, under certain conditions and within certain limits, compensate part of the emissions resulting from the use of fossil fuels and deforestations. Quantification of stocks of biomass and carbon dioxide contained in agroforestry systems has become an international priority within the framework of the implementation of REDD+ mechanism. Estimates of stocks of carbon in woody biomass, dead organic matter, belowground biomass, litter, herbaceous and lianas plant biomass were incorporated in allometric equation based on non-destructive method. The total carbon stock evaluated in the parkland of Tectona grandis was 207.34 ton/3ha out of which woody biomass accounted for 130.19 ton/3ha belowground biomass (40.4 ton/3ha), dead organic matter (22.85 ton/3ha), litter (9.09 ton/3ha), herbaceous plant biomass (2.28 ton/3ha) and lianas (2.53 ton/3ha). The aboveground biomass therefore contributed approximately 62.80 % of the total stock of carbon assessed. This show the considerable contribution of Tectona grandis parkland to climate change mitigation in Cameroon.

Abstract The article presents discussion on the state and prospects of bioenergy development in the context of rationalization of energy crops application as resource potential of Ukraine. Along with the development of society and increase of life intensity, the needs of mankind with regard to energy resources are increasing. The reduction rates of traditional types of energy resources are progressively growing, and their shortage is increasing. In addition, Ukraine belongs to import-dependent countries in the energy sector. At the expense of its own sources, our country provides only about half of the energy needs, while domestic national economy is one of the most energy-intensive industries in the world. In this regard, there is an urgent need to search for new, alternative sources of energy. Taking into account the potential present in Ukraine, the biomass use for energy production is the most attractive option. However, along with this, there is a problem of purposeful use of the agricultural land and a competitive struggle between agricultural products for nutrition and energy purposes. At the same time, many problems arise, which concerdevelopment of an appropriate legislative framework, methodological approaches to the economic, environmental and social efficiency of production and use of biological types of energy.

Bioenergy produced from perennial feedstocks such as woody biomass could serve as an opportunity to strengthen local and regional economies and also jointly produce various environmental services. In order to assess the potential for biomass-based bioenergy, it’s essential to characterize the interest that potential biomass suppliers have in such an endeavor. In the U.S. Great Plains region, this largely means assessing relevant perceptions of farmers and ranchers. We conducted a series of farmer and rancher oriented focus groups in North Dakota, South Dakota, Nebraska and Kansas to qualitatively explore opinions about the role that trees can play in agriculture and interest in woody biomass systems within existing Northern Great Plains (NGP) farms and ranches. Our findings suggest that farmer and ranchers generally value the role that trees, or tree-based practices like windbreaks can play in agriculture particularly on marginal farmland in terms of conservation or crop protection. Yet relative to the potential of trees as a biomass crop there is a distinct lack of knowledge and skepticism. Farmers and ranchers also noted variable degrees of risk concern and uncertainty regarding investing in tree-based systems, as well as a number of perceived external market related constraints to integrating trees within their managed systems. Most of the participants recognized that if biomass production or an increase in tree planting and management in general were to expand in the NGP region, government programs would likely be required to provide much needed technical guidance and financial incentives. As the NGP regional bioeconomy continues to emerge and expand, private and public investment relative to niche bioenergy feedstocks such as woody biomass should address the type of information needs that farmers and ranchers have relative to integrating biomass production into existing farm and ranch systems.

Spatial Identification

Mapping aboveground woody biomass (AGB) on abandoned agricultural land (AAL) is required by relevant stakeholders to monitor the spatial dynamics of farmland afforestation, to assess the carbon sequestration, and to set the appropriate management of natural resources. The objective of this study was, therefore, to present and assess a workflow consisting of (1) the spatial identification of AAL based on a combination of airborne laser scanning (ALS) data, cadastral data, and Land Parcel Identification System data, and (2) the prediction of AGB on AAL using an area-based approach and a nonparametric random forest (RF) model based on a combination of field and ALS data. Part of the second objective was also to evaluate the applicability of (1) the author-developed algorithm for the calculation of ALS metrics and (2) a single comprehensive RF model for the whole area of interest. The study was conducted in the forest management unit Vígľaš (Slovakia, Central Europe) covering a total area of 12,472 ha. Specifically, five reference areas consisting of 11,194 reference points were used to assess the accuracy of the spatial identification of AAL, and seventy-five ground reference plots were used for the development of the ALS-based AGB model and for assessing the accuracy of the AGB map. The overall accuracy of the spatial identification of AAL was found to be 93.00% (Cohen’s kappa = 0.82). The difference between ALS-predicted and ground-observed AGB reached a relative root mean square error (RMSE) at 26.1%, 33.1%, and 21.3% for the whole sample size, plots dominated by shrub species, and plots dominated by tree species, respectively.

This research aims to determine the carryng capacity of agricultural land food crops in Southern Districts Minahasa. This research from preparation of the final report of the study conducted in March to June 2015. Data is taken from secondary data obtained from the Central Statistical Agencies and the Department of Agriculture in Southern Minahasa. The data analysis used is the level of the carryng capacity of agricultural land. From the research the level of the carrying capacity of agricultural land, the lowest in the sub-district of Modoinding  was in the amount of 0,076 and the highest in the sub-district of Maesaan that is equal to 1,113. Carrying value of the level of agricultural land in the Southern District Minahasa amounted to 0,414. This means that the Southern Minahasa District has not been able to perform self-suffieciency and has not been able to provide a decent life for its people, therefore the carrying capacity of agricultural land food crops in Southern Minahasa district needs to be improved especially through increased productivity and reduce the rate of population growth.
