Abstract:

Given the ambitious EU targets to further decarbonise the economy, it can be expected that the demand for lignocellulosic biomass will continue to grow. Provisioning of part of this biomass by dedicated biomass crops becomes an option. This study presents integrated approach for crop allocation based on land availability and crop requirements. The model analysis to investigate the potential extension of unused land and its suitability for lignocellulosic crops was carried out in 37 European countries at the NUTS3 level. The CAPRI model predicts future land use changes and was used as a basic

Abstract:

Often, in dynamical systems, such as farmers’ crop choices, the dynamics are driven by external non-stationary factors, such as rainfall and agricultural input and output prices. Such dynamics can be modelled by a non-stationary stochastic process, where the transition probabilities are functions of such external factors. We propose using a multinomial logit model for these transition probabilities, and investigate the problem of estimating the parameters of this model from data. We adapt the work of Chen and Ibrahim to propose a conjugate prior distribution for the parameters of the multinomi

Abstract:

<p> This research is composed of three essays. It highlights the driving factors of land conversion and crop acreage response focusing on North Dakota agriculture and estimates the benefits of conservation land measures at west central South Dakota watershed. The major questions that are addressed here are how and why agricultural producers decide among different land use choices, crop selection, and land conservation measures and how their decision vary over time? The first essay examines the long run land conversion trend interconnected with change in crop, oil, and ethanol prices, climate a

Ground truthing actual crop types in an area can be expensive and time-consuming. The California Department of Water Resources attempts to ground truth land use in each county in California every five years. However, this is limited by budgetary constraints and often results in infrequent (more than every ten years) surveying of many counties. An accurate accounting of crops growing in a region is important for a variety of purposes including farm production estimates, groundwater and surface water modeling, evapotranspiration estimation, water planning, research applications, etc. Agricultura

The aim of this project is to explore the social and ethical dimensions of the agricultural production of perennial energy crop and crop residues for energy. Biomass – any living or recently living matter – is being promoted in industrialised countries as part of the transition from fossil fuels to an economy based on renewable energy. Various challenges face the use of bioenergy however. One particularly controversial and high profile example has been the use of food crop biofuels in transport which are seen to conflict with food production and to cause significant environmental damage.

Agricultural productivity in the Sub Saharan African (SSA) region has been cited to be low (Suttie & Benfica, 2016). As a result, there is a consistent call for evolution in smallholder farming. In addition to improving agricultural productivity, this evolution should factor in adaptation to climate variability and change. To achieve this, the use of sound and sustainable agricultural and land management practices (SALMPs) stands paramount. Among these include: (1) improved agronomic practices such as the use of improved seed varieties (HYV), (2) integrated nutrient management practices (INM),

Crop management practices, such as soil tillage and crop residue management, are land management activities with potentially large impacts on carbon (C) cycling and climate at the global scale. Improvements in crop management practices, such as conservation tillage or 'no-till' (NT), have been proposed as climate change mitigation measures because such practices may alter C cycles through increased sequestration of soil C in agricultural soils. Despite their potential importance, regional to global scale data are lacking for many crop management practices, and few studies have evaluated the po

Environmental stresses are main factors limiting crop production worldwide. Water stress is a primary cause of crop losses, reducing average yields for most of the major crops by more than 50%, particularly in arid and semi-arid regions. Moreover, the increasing frequency of dry periods in many regions of the world, as a consequence of the global warming, frequently results in saline soils with low agricultural potential. Bacteria are among the first colonizers of soil habitats at different stages of development, largely contributing in determining soil structure and composition. In this conte

Abstract:

The agronomical evaluation and the comparative work of six multiannual forage species was conducted in the facilities of the Benson Institute, in the community of Contorno de Letanias, Ingavi province, La Paz. The objectives were to evaluate the agronomic behavior, as well as to evaluate the dry matter (DM) yield of six multiannual forage species (grasses) under local conditions, and to determine the partial cost of production of the studied species. The annual mean temperature was 9.14°C, and 517.6 mm of precipitation. The test was conducted under the random block design test, with six differ

Abstract:

<p>The government of Zimbabwe started implementing its fast track resettlement programme in July 2000, the objective being to accelerate both land acquisition and land redistribution. This programme witnessed a massive movement of people from various localities into mainly large-scale commercial farms in search of agricultural land. Under this programme, people were settled under the A1 model (which involves villages and land use pattern similar to those found in communal areas) as well as the A2 model, which involves commercial farming. This study investigates, documents and analyses the oppo

Abstract:

Mit dem Anbau von Zwischenfrüchten kann die Nitratbelastung des Grundwassers reduziert oder niedrig gehalten werden. Zwischenfrüchte verbessern und erhalten die Bodenfruchtbarkeit, erhöhen die biologische Bodenaktivität und bieten Schutz vor Erosion. Auf Feldversuchsanlagen wurden Stickstoffaufnahme, Biomasseerträge, Unkrautunterdrückung und die Kosten des Anbaus von Zwischenfrüchten und Zwischenfruchtgemenge untersucht und ausgewertet.
