High Scenario

Energy crop expansion can increase land demand and generate displacement of food crops, which impacts greenhouse gas (GHG) emissions mainly through land-use change (LUC). Increased agricultural productivity could compensate for this. Our study aims to evaluate the regional combined GHG emissions of increasing agricultural yields for food crop and beef production and using the generated surplus land for biomass production to replace fossil fuels in the Orinoquia region of Colombia until 2030. The results show that surplus land for biomass production is obtained only when strong measures are applied to increase agricultural productivity. In the medium and high scenario, a land surplus of 0.6 and 2.4 Mha, respectively, could be generated. Such intensification results in up to 83% emission reduction in Orinoquia’s agricultural sector, largely coming from increasing productivity of cattle production and improving degraded pastures. Biofuel potential from the surplus land is projected at 36 to 368 PJ per year, with a low risk of causing indirect LUC, and results in GHG emission reductions of more than 100% compared to its fossil fuel equivalent. An integrated perspective of the agricultural land use enables sustainable production of both food and bioenergy.

Uncertainty Estimates

<p>In order to mitigate climate change and reduce the anthropogenic greenhouse gas (GHG) emissions, the Kyoto protocol has been adopted in 1997 and the Paris Agreement entered into force in 2016. The Paris Agreement have ratified 190 out of 197 Parties of the United Nations Framework Convention on Climate Change (UNFCCC) and Croatia is one of them as well. Each Party has obliged regularly to submit the national inventory report (NIR) providing the information on the national anthropogenic GHG emissions by sources and removals by sinks to the UNFCCC. Reporting under the NIR is divided into six categories / sectors, and one of them is land use, land use change and forestry (LULUCF) sector, where an issue of uncertainty estimates on carbon emissions and removals occurs. As soil respiration represents the second-largest terrestrial carbon flux, the national studies on soil respiration can reduce the uncertainty and improve the estimation of country-level carbon fluxes. Due to the omission of national data, the members of the University of Zagreb Faculty of Agriculture, Department of General Agronomy have started to study soil respiration rates in 2012, and since then many different studies on soil respiration under different agricultural land uses (i.e. annual crops, energy crop and vineyard), management practices (i.e. tillage and fertilization) and climate conditions (i.e. continental and mediterranean) in Croatia have been conducted. The obtained site specific results on field measurements of soil carbon dioxide concentrations by <em>in situ</em> closed static chamber method will be presented in this paper.</p>

Abstract Background The gradual conversion of rangelands into other land use types is one of the main challenges affecting the sustainable management of rangelands in Teltele. This study aimed to examine the changes, drivers, trends in land use and land cover (LULC), to determine the link between the Normalized Difference Vegetation Index (NDVI) and forage biomass and the associated impacts of forage biomass production dynamics on the Teltele rangelands in Southern Ethiopia. A Combination of remote sensing data, field interviews, discussion and observations data were used to examine the dynamics of LULC between 1992 and 2019 and forage biomass production. Results The result indicate that there is a marked increase in farm land (35.3%), bare land (13.8%) and shrub land (4.8%), while the reduction found in grass land (54.5%), wet land (69.3%) and forest land (10.5%). The larger change in land observed in both grassland and wetland part was observed during the period from 1995–2000 and 2015–2019, this is due to climate change impact (El-Niño) happened in Teltele rangeland during the year 1999 and 2016 respectively. The quantity of forage in different land use/cover types, grass land had the highest average amount of forage biomass of 2092.3 kg/ha, followed by wetland with 1231 kg/ha, forest land with 1191.3 kg/ha, shrub land with 180 kg/ha, agricultural land with 139.5 kg/ha and bare land with 58.1 kg/ha. Conclusions The significant linkage observed between NDVI and LULC change types (when a high NDVI value, the LULC changes also shows positive value or an increasing trend). In addition, NDVI value directly related to the greenness status of vegetation occurred on each LULC change types and its value directly linkage forage biomass production pattern with grassland land use types. 64.8% (grass land), 43.3% (agricultural land), 75.1% (forest land), 50.6% (shrub land), 80.5% (bare land) and 75.5% (wet land) more or higher dry biomass production in the wet season compared to the dry season.

Biofuel Policies

The use of agricultural-based biofuels has expanded. Discussions on how to assess green house gas (GHG) emissions from biofuel policies, specifically on (non-observed) land-use change (LUC) effects involve two main topics: (i) the limitations on the existing methodologies, and (ii) how to isolate the effects of biofuels. This paper discusses the main methodologies currently used by policy-makers to take decisions on how to quantify LUCs owing to biofuel production expansion. It is our opinion that the concerns regarding GHG emissions associated with LUCs should focus on the agricultural sector as a whole rather than concentrating on biofuel production. Actually, there are several limitations of economic models and deterministic methodologies for simulating and explaining LUCs resulting from the expansion of the agricultural sector. However, it is equally true that there are avenues of possibilities to improve models and make them more accurate and precise in order to be used for policy-making. Models available need several improvements to reach perfection. Any top model requires a concentration of interdisciplinary designers in order to replicate empirical evidence and capture correctly the agricultural sector dynamics for different countries and regions. Forgetting those limitations means that models will be used for the wrong purposes.

Policy Application

This paper is focused on the application of linear programming (LP) in combination with a geographic information system (GIS) in planning agricultural land-use strategies. One of the essential inputs for planning any agricultural land-use strategy is a knowledge of the natural resources. This is even more critical in small countries such as those in the Eastern Caribbean, where land-area limitations dictate a greater need for careful assessment and management of these resources. The first step of the proposed methodology is to obtain an assessment of the natural resources available to agriculture. The GIS is used to delineate land-use conflicts and provide reliable information on the natural-resource database. This is followed by combining the data on natural resources with other quantifiable information on available labour, market forecasts, technology, and cost information in order to estimate the economic potential of the agricultural sector. LP is used in this step. Finally, the GIS is applied again to map the crop and land-allocation patterns generated by the LP model. The results are concrete suggestions for resource allocation, farm-size mix, policy application, and implementation projects.

The Impact

Undistorted factor markets are a perquisite for efficient allocation of resources and growth in production. In Oman by 2013, only 16% of households have reported agriculture as the main occupation and 53% have reported nonagricultural government employment as the main occupation. This situation is hypothesized to be related to the labor market; where government legislated higher remuneration in the nonagricultural government sector vis-a-vis agricultural sector, influences Omani farmers to move to nonagricultural employment, causing reduced cultivated area and farm production. The study uses operations research methods to quantify the impact of labor market policies on agricultural employment, farm gross income and land use intensity (proxy for farm production and food security). It is found that the shift of Omani labor from agriculture is influenced by higher wages in the nonagricultural sectors. The agricultural land use intensity is thereby decreased. The policy of allowing hiring of expatriate labor is beneficial in overcoming labor scarcity. However, in the long-run both farm productivity need to improve to be competitive with legislated income receivable from nonagricultural employment and ideally labor markets need to operate freely, to enhance food security and assure employment of Omani labor in agriculture.

An important component of forming the basis for the balanced development of the domestic agricultural sector is the reproduction and protection of land resources. A significant part of the problems here are directly related to the insufficiency and inefficiency of financial support for agricultural land use. The purpose of the article is to reveal the financial and credit mechanism for ensuring balanced land use and to develop proposals for improving the financial support for the reproduction and protection of agricultural land through the introduction of tax incentives. The financial and credit mechanism for stimulating balanced agricultural land use can be defined as structurally complex and diversified; it has its own features to ensure its implementation and influence on the subjects of financial and credit relations in the direction of regulating their activities. It is established that financial relations in agricultural land use combine a very large chain of relationships between the state, enterprises, individuals and financial institutions in terms of financial support for the reproduction of agricultural land use. The financial and credit mechanism for stimulating balanced agricultural land use can be defined as structurally complex and branched; it has its own features to ensure its implementation and influence on the subjects of financial and credit relations in the direction of regulating their activities. It is proved that it is necessary to create such conditions of management that unbalanced use of land became economically unprofitable. The level of profitability and income of land users should become dependent on the degree of achievement of balanced agricultural land use, which is determined by a set of agrochemical indicators of the quality of land used for agricultural activities. In order to financially ensure the reproduction of balanced agricultural land use, the introduction of tax incentives is proposed. These include the formation of general favorable tax conditions for enterprises in the agricultural sector of the economy and the introduction of targeted tax benefits. It is established that the use of the above financial and credit levers and incentives for the development of balanced land use is the most accepted in today's challenges, because it has minimal impact on the expenditure side of the state budget.

Abstract The land sector needs to increase biomass production to meet multiple demands while reducing negative land use impacts and transitioning from being a source to being a sink of carbon. The new Common Agricultural Policy of the EU (CAP) steers towards a more needs-based, targeted approach to addressing multiple environmental and climatic objectives, in coherence with other EU policies. In relation to this, new schemes are developed to offer farmers direct payments to adapt practices beneficial for climate, water, soil, air and biodiversity. Multifunctional biomass production systems have potential to reduce environmental impacts from agriculture while maintaining or increasing biomass production for the bioeconomy across Europe. Here, we present the first attempt to model the deployment of two such systems, riparian buffers and windbreaks, across >81.000 landscapes in Europe (EU27 + UK), aiming to quantify the resulting ecosystem services and environmental benefits, considering three deployment scenarios with different incentives for implementation. We found that these multifunctional biomass production systems can reduce N emissions to water and soil loss by wind erosion, respectively, down to a “low” impact level all over Europe, while simultaneously providing substantial environmental co-benefits, using less than 1% of the area under annual crops in the EU. The GHG emissions savings of utilizing the biomass produced in these systems for replacing fossil alternatives, combined with the increases in soil organic carbon, correspond to 1-1,4% of total GHG emissions in EU28. The introduction of “eco-schemes” in the new CAP may resolve some of the main barriers to implementation of large-scale multifunctional biomass production systems. Increasing the knowledge of these opportunities among all EU member states, before designing and introducing country-specific Eco-scheme options in the new CAP, is critical.
