    Food and Agriculture in PNG (2021)
    ANU Press
    Details
    Publication Date: 2022-04-28
    Description: Agriculture dominates the rural economy of Papua New Guinea (PNG). More than five million rural dwellers (80% of the population) earn a living from subsistence agriculture and selling crops in domestic and international markets. Many aspects of agriculture in PNG are described in this data-rich book. Topics include agricultural environments in which crops are grown; production of food crops, cash crops and animals; land use; soils; demography; migration; the macro-economic environment; gender issues; governance of agricultural institutions; and transport. The history of agriculture over the 50 000 years that PNG has been occupied by humans is summarised. Much of the information presented is not readily available within PNG. The book contains results of many new analyses, including a food budget for the entire nation. The text is supported by 165 tables and 215 maps and figures.

    Agriculture and Food Security in China (2021)
    ANU Press
    Details
    Publication Date: 2024-03-13
    Description: China’s accession to the World Trade Organization (WTO) has had profound consequences for the structure of its economy, and there will many more before the full benefits of an open trading regime will be realised. Agriculture and Food Security in China explains the background to China’s WTO accession and links accession to reforms beginning as far back as 1979. The book highlights China’s policymakers’ decision to move away from protectionism and gain self-sufficiency, and illustrates how China’s step away from direct participation in the agricultural sector to indirect regulatory involvement and liberalisation could encourage further economic growth. Yet not all economic growth is cost-free. Agriculture and Food Security in China explores the short-term impacts of WTO accession as well as the mid and long-term implications of greater market involvement at an economy-wide and regional level. Growing divides between coastal and inland regions—and differences in rural and urban growth—will require a better understanding of the consequences of greater market dependency. Agriculture and Food Security in China adds to the existing knowledge of China’s agricultural growth as well as the impacts and interrelationships between WTO accession and China’s participation in other regional free trade agreements.

    Learning from agri-environment schemes in Australia. Investing in biodiversity and other ecosystem services on farms (2021)
    ANU Press
    Details
    Publication Date: 2024-03-23
    Description: Learning from agri-environment schemes in Australia is a book about the birds and the beef — more specifically it is about the billions of dollars that governments pay farmers around the world each year to protect and restore biodiversity. After more than two decades of these schemes in Australia, what have we learnt? Are we getting the most out of these investments, and how should we do things differently in the future? Involving contributions from ecologists, economists, social scientists, restoration practitioners and policymakers, this book provides short, engaging chapters that cover a wide spectrum of environmental, agricultural and social issues involved in agri-environment schemes.

    BODIUM—A systemic approach to model the dynamics of soil functions (2023)
    Blackwell Publishing Ltd | Oxford, UK
    Details
    Publication Date: 2024-01-26
    Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉The increasing demand for biomass for food, animal feed, fibre and bioenergy requires optimization of soil productivity, while at the same time, protecting other soil functions such as nutrient cycling and buffering, carbon storage, habitat for biological activity and water filter and storage. Therefore, one of the main challenges for sustainable agriculture is to produce high yields while maintaining all the other soil functions. Mechanistic simulation models are an essential tool to fully understand and predict the complex interactions between physical, biological and chemical processes of soils that generate those functions. We developed a soil model to simulate the impact of various agricultural management options and climate change on soil functions by integrating the relevant processes mechanistically and in a systemic way. As a special feature, we include the dynamics of soil structure induced by tillage and biological activity, which is especially relevant in arable soils. The model operates on a 1D soil profile consisting of a number of discrete layers with dynamic thickness. We demonstrate the model performance by simulating crop growth, root growth, nutrient and water uptake, nitrogen cycling, soil organic matter turnover, microbial activity, water distribution and soil structure dynamics in a long‐term field experiment including different crops and different types and levels of fertilization. The model is able to capture essential features that are measured regularly including crop yield, soil organic carbon, and soil nitrogen. In this way, the plausibility of the implemented processes and their interactions is confirmed. Furthermore, we present the results of explorative simulations comparing scenarios with and without tillage events to analyse the effect of soil structure on soil functions. Since the model is process‐based, we are confident that the model can also be used to predict quantities that have not been measured or to estimate the effect of management measures and climate states not yet been observed. The model thus has the potential to predict the site‐specific impact of management decisions on soil functions, which is of great importance for the development of a sustainable agriculture that is currently also on the agenda of the ‘Green Deal’ at the European level.〈/p〉

    Temperature and soil moisture change microbial allocation of pesticide‐derived carbon (2023)
    Blackwell Publishing Ltd | Oxford, UK
    Details
    Publication Date: 2024-03-18
    Description: 〈title xmlns:mml="http://www.w3.org/1998/Math/MathML"〉Abstract〈/title〉〈p xmlns:mml="http://www.w3.org/1998/Math/MathML" xml:lang="en"〉Temperature and soil moisture are known to control pesticide mineralization. Half‐life times (DT〈sub〉50〈/sub〉) derived from pesticide mineralization curves generally indicate longer residence times at low soil temperature and moisture but do not consider potential changes in the microbial allocation of pesticide‐derived carbon (C). We aimed to determine carbon use efficiency (CUE, formation of new biomass relative to total C uptake) to better understand microbial utilization of pesticide‐derived C under different environmental conditions and to support the conventional description of degradation dynamics based on mineralization. We performed a microcosm experiment at two MCPA (2‐methyl‐4‐chlorophenoxyacetic acid) concentrations (1 and 20 mg kg〈sup〉−1〈/sup〉) and defined 20°C/pF 1.8 as optimal and 10°C/pF 3.5 as limiting environmental conditions. After 4 weeks, 70% of the initially applied MCPA was mineralized under optimal conditions but MCPA mineralization reached less than 25% under limiting conditions. However, under limiting conditions, an increase in CUE was observed, indicating a shift towards anabolic utilization of MCPA‐derived C. In this case, increased C assimilation implied C storage or the formation of precursor compounds to support resistance mechanisms, rather than actual growth since we did not find an increase in the 〈italic toggle="no"〉tfdA〈/italic〉 gene relevant to MCPA degradation. We were able to confirm the assumption that under limiting conditions, C assimilation increases relative to mineralization and that C redistribution, may serve as an explanation for the difference between mineralization and MCPA dissipation‐derived degradation dynamics. In addition, by introducing CUE to the temperature‐ and moisture‐dependent degradation of pesticides, we can capture the underlying microbial constraints and adaptive mechanisms to changing environmental conditions.〈/p〉
