  3. Artikel: Labour productivity: The forgotten yield gap

    Cock, James / Prager, Steven / Meinke, Holger / Echeverria, Ruben

    Agricultural systems. 2022 Aug., v. 201

    Abstract Crop yields and labour productivity have increased markedly over the past 70 years. In agriculturally advanced countries, increases in labour productivity – that is, increases in the economic output per unit of labour input – have been several-fold greater than corresponding increases in yield. The gap in labour productivity between the Global North and the Global South is now much greater than the yield gap. This large labour productivity gap, unless remedied, will: (i) condemn many farmers in the Global South to live in poverty; and (ii) make them less competitive and force them to follow the well-established trend of exiting farming altogether, which (iii) will contribute to greater dependence on imported food in many countries. Despite this situation, agricultural development agencies tend to emphasise biological yield per unit area to satisfy the increasing demand for more nutritious and varied food products. Policies are skewed towards low-cost food for urbanites, often with benign neglect of the welfare of the rural populace, particularly the women who produce the food. We suggest R&D policies should pay more attention to enhanced labour productivity, while not neglecting increased yield, to meet the dual needs of food for the overall population and prosperity in rural areas. Many technology-based interventions exist to increase labour productivity, nevertheless, single technological fixes are unlikely to bring about major changes. Furthermore, the adoption of new technologies and novel enterprises required to increase labour productivity, particularly those related to high value crops for farmers with limited access to land, depends on an inclusive innovation systems approach. Policies are needed that support the development of new enterprises, soft infrastructure, a stronger industrial base and inclusive partnerships with education providers such as universities, research centres, secondary and tertiary education facilities. This is not to say that producers in the Global South should follow the Global North, rather that policy should focus on interventions that improve labour productivity of both women and men tailored to enhance ongoing development within the local context.

  5. Artikel ; Online: Assessing temperature‐based adaptation limits to climate change of temperate perennial fruit crops

    Abstract Temperate perennial fruit and nut trees play varying roles in world food diversity—providing edible oils and micronutrient, energy, and protein dense foods. In addition, perennials reuse significant amounts of biomass each year providing a unique resilience. But they also have a unique sensitivity to seasonal temperatures, requiring a period of dormancy for successful growing season production. This paper takes a global view of five temperate tree fruit crops—apples, cherries, almonds, olives, and grapes—and assesses the effects of future temperature changes on thermal suitability. It uses climate data from five earth system models for two CMIP6 climate scenarios and temperature‐related indices of stress to indicate potential future areas where crops cannot be grown and highlight potential new suitable regions. The loss of currently suitable areas and new additions in new locations varies by scenario. In the southern hemisphere (SH), end‐century (2081–2100) suitable areas under the SSP 5–8.5 scenario decline by more than 40% compared to a recent historical period (1991–2010). In the northern hemisphere (NH) suitability increases by 20% to almost 60%. With SSP1‐2.6, however, the changes are much smaller with SH area declining by about 25% and NH increasing by about 10%. The results suggest substantial restructuring of global production for these crops. Essentially, climate change shifts temperature‐suitable locations toward higher latitudes. In the SH, most of the historically suitable areas were already at the southern end of the landmass limiting opportunities for adaptation. If breeding efforts can bring chilling requirements for the major cultivars closer to that currently seen in some cultivars, suitable areas at the end of the century are greater, but higher summer temperatures offset the extent. The high value of fruit crops provides adaptation opportunities such as cultivar selection, canopy cooling using sprinklers, shade netting, and precision irrigation.

    Abstract Eco‐efficiency in the simplest of terms is about achieving more with less—more agricultural outputs, in terms of quantity and quality, for less input of land, water, nutrients, energy, labor, or capital. The concept of eco‐efficiency encompasses both the ecological and economic dimensions of sustainable agriculture. Social and institutional dimensions of sustainability, while not explicitly captured in eco‐efficiency measures, remain critical barriers and opportunities on the pathway toward more eco‐efficient agriculture. This paper explores the multidimensionality of the eco‐efficiency concept as it applies to agriculture across diverse spatial and temporal scales, from cellular metabolisms through to crops, farms, regions, and ecosystems. These dimensions of eco‐efficiency are integrated through the presentation and exploration of a framework that explores an efficiency frontier between agricultural outputs and inputs, investment, or risk. The challenge for agriculture in the coming decades will be to increase productivity of agricultural lands in line with the increasing demands for food and fiber. Achieving such eco‐efficiency, while addressing risk and variability, will be a major challenge for future agriculture. Often, risk will be a critical issue influencing adoption; it needs explicit attention in the diagnosis and intervention steps toward enhancing eco‐efficiency. To ensure food security, systems analysis and modeling approaches, combined with farmer‐focused experimentation and resource assessment, will provide the necessary robust approaches to raise the eco‐efficiency of agricultural systems.

    Abstract Irrigation systems face unforeseeable changes in climate, technologies, and societal preferences during their lifetime, potentially rendering them obsolete or inadequate. To remain functional, irrigation systems need to be adaptive to changes as the future unfolds. Past approaches to irrigation system design were largely informed by engineering or economic criteria. This is increasingly recognised as insufficient. We provide examples of contemporary irrigation systems in Australia to highlight the need for planning and design approaches that recognise the complex interactions between human and water systems and embrace unknowns. We review literature on hydro-social interactions and dynamic adaptive pathways to provide insights for the development of adaptive irrigation systems.
