To understand how various factors influence phenological patterns like fruit production and the extent of phenological variability as survival strategy in different environments, fruit production of shea trees was studied in different agroclimatic zones (North Sudanian, South Sudanian and North Guinean) in Mali. Three sites were selected for this study and in each site; two stands (field and fallow) were concerned. For each stand, three “land use history or land management" i.e. new fields/fallows (1-5 years), medium (6-10 years) and old (10 years) were considered and permanent plots of 0.25 ha were established. 60 adult shea trees (DBH) ≥ 10 cm) were selected by site and monitored for fruit production assessment. The nested analysis of variance on the yield showed a significant site effect and significant effect of land use history within stand. However, stand effect within site was not significant. Factors like site and land management (land use history) appear to be determinant for fruit production of V. paradoxa. The site of Mperesso in the South Sudanian zone showed the highest fruit mean yield (11 kg/tree), significantly higher than the fruit mean yield observed at Daelan (7 kg/tree) in the North Sudanian zone and that observed at Nafégué (6 kg/tree) in the North Guinean zone. For field stand, old fields showed highest mean yield in all sites. For fallow stand, old fallows showed the lowest mean yield in most of cases. Different pattern was observed between field and fallow stands regarding the effect of land management. More fields are aged, more they influence positively fruit production whereas more fallows are aged, and more they influence negatively fruit production. This study highlighted the importance of land management practices and therefore, any domestication program to be successful should consider the potential effect of management practices.

The Uk

<p>In this study, we explore plausible future states of soil organic matter, biomass, food production and soil greenhouse gas emissions across the UK under a range of climate, land use and land management scenarios. We use state-of-the-art soil biochemistry model, N14CP-Ag, combined with UKCP18 climate scenarios and ASSET land cover change and crop scenarios mapped onto a UK-wide grid with around 100,000 land parcels. Historic runs cover the period from the start of the Holocene interglacial (-12 kyr BP) to 2015; scenarios run from 2016 out to 2100. The results show variations of soil organic carbon (SOC) of around 10% between 2016 and 2100 relative to the simulated starting value of 1.4 Gton in 2015, with reductions of up to 7% under arable expansion scenarios and increases of up to 3% under grassland restoration scenarios. The effect of changing cropping patterns on UK-wide SOC is comparatively small. As climate scenarios move from lower to higher global emissions, the SOC reductions under arable expansion become more pronounced, while the SOC increases under grassland restoration diminish and eventually turn into losses. UK-wide crop yields show resilience to climate change and are maximised for the arable expansion scenario with protected sites of special scientific interest. Soil CO2 and nitrogen emissions get progressively higher in warmer climates. The results of this study are expected to contribute to a future UK agricultural policy aimed at rewarding farmers for sustainable land management practices.</p>

Insight Into

The Dulung River flows across West Bengal and Jharkhand in India. The geographical variables present within the basin area are categorised into groups like Physiographic, Morphometric and Land Use-Land Cover (LULC) attributes. These facets are mapped and overlain in a GIS environment and correlations drawn between them. Factor Scores obtained through Principal Component Analysis are further compared and correlated. The different variables are fused to obtain a comprehensive grouping of the above three facets that is reflective of the overall terrain attributes and its overlying LULC classes. Through this, within the Dulung River Basin, three broad Physiographic-Soil-Land Use Units (PSLUs) are identified, which comprise of the structural ridges and residual hills, piedmont plains and floodplains. For further insight into existing LULC-landform relations, select villages across the basin landscape are examined in detail. The relations derived help in suggesting possible land management practices in this region.

Abstract Soil health conceptualized as a measurable ecosystem property provides a powerful tool for monitoring progress in restoration projects or implementation of best management practices to promote sustainable agroecosystems. We surveyed soils collected from a range of land uses (i.e., protected native and non-native forest, managed pasture, unmanaged previously intensive agricultural lands, organic cropland, and conventional cropland) across a range of soil orders (Oxisol, Mollisol, Andisol, Inceptisol, and Vertisol) on three Hawaiian Islands. Forty-six metrics associated with soil health and encompassing biological, chemical, and physical properties were measured. In this multivariate survey, the most distinct group was the unmanaged, previously intensive agriculture lands, which was significantly different from all other land uses regardless of mineralogy. Importantly, the soil health of well-managed pastures in Hawaiʻi was not different from protected forests, suggesting that well-managed grazing lands may be as healthy and resilient as protected forests. A suite of 11 readily measured parameters emerged out of a first-principle approach to determining a holistic indication of soil health across a range of soils and systems in Hawaiʻi encompassing much of the diversity in the tropics and subtropics. Every land use may improve its soil health status within a reasonable range of expectations for a soil’s land use history, current land use, and mineralogy. Key drivers of the measures for soil health, including intensive land use history, current land use practices, and mineralogy, must be interwoven into the soil health index, which should set minimum and maximum benchmarks and weight parameters according to equitable standards.

The North Otago area has a climate that often fluctuates from severe drought to flood in a short space of time. The climatic extremes, and some unsustainable land use practices can put the area's fragile loessial soils at risk of water and wind erosion. This paper outlines an approach used in North Otago which has enabled the community to identify its sustainability and environmental issues and begin to make changes to land use and farmer attitudes. A group of key farmers was brought together to oversee the preparation of Sustainable Land Management Guidelines for the downlands. (This group became the North Otago Sustainable Land Management Group - NOSLaM Group.) From this grew a wide-ranging community-driven project with a full-time co-ordinator, and a vision to have most land users adopting sustainable farming systems. This should ensure the area is ready to meet the world market demands for environmental quality in food and fibre production. The Group will promote individual environmental farm plans which will have a monitoring component. Some farmers will work towards some form of property accreditation such as ISO 14001. This pilot project will be highlighting the economic benefits of environmentally sound farming methods, through seminars, field-days, newsletters and a demonstration farm. The Group is working in partnership with farmers, the processing industry and marketing people to identify market opportunities for the area's food and fibre produced by environmentally friendly farming systems.

Aichi Biodiversity Targets

A brief historical overview of approaches to study the problem of land use and land degradation in the MAB UNESCO program is provided. Over the past 50 years these issues remain important although the general strategic approach to their research and solving has changed from a multilateral study of land management and land degradation in different geographic and socio-economic conditions with an emphasis on natural diversity, to practices and approaches of sustainable land management in biosphere reserves, as reflected in MAB Strategy (2015-2025) and Lima Action Plan (2016-2025). Many of the MAB initiatives in the field of sustainable land management and combating land degradation have been further reflected and revised in different international programs and conventions. The development of these approaches and the integration of the MAB program with other modern activities can significantly increase the effectiveness of the results of Strategic Direction “A” of the Lima Action Plan on the use of UNESCO Biosphere Reserves as models for sustainable development. Five objectives are proposed for closer cooperation of the MAB program and its network of biosphere reserves with other international and national measures for promoting sustainable land management practices and combating land degradation: 1) using biosphere reserves as priority sites and observatories for comparative assessments of indicators of land degradation neutrality (LDN) for protected areas and adjacent territories in similar bioclimatic conditions; 2) use of data obtained through the series of observations in the territory of protected areas as the most important additional or alternative indicators and measures for the LDN interpretation; 3) biosphere reserves as models for selecting effective solutions reflecting the triad of adaptive actions to avoid degradation, reduce the rate of degradation and restore previously degraded lands; 4) achieving LDN on the territory of biosphere reserves through the implementation of the Aichi biodiversity targets; 5) the use of LDN as a criterion for evaluating the effectiveness of the activities of biosphere reserves. Preliminary results of the LDN assessment for Central Chernozem State Natural Biosphere Reserve and Middle Volga Integrated Biosphere Reserve and their adjacent territories provided to demonstrate the possibility of performing some of the objectives listed.

The Impact

The land use and management data requirements for assessing, monitoring and reporting on the impact of agricultural production practices on the environment, especially in a country as large as Canada, are considerable. In view of the fact that environmental assessments are a relatively new phenomenon, data collection activities targeted toward these needs are not widespread. As a result, we find it necessary to acquire and integrate a variety of data sources with differing time lines, spatial scales and sampling frameworks. This paper uses our current activities with respect to Kyoto reporting as a focus to present and discuss the types of data required and the spatial analysis and integration procedures being developed to provide them. The essential data for this activity include the area of crop and land use types, land use changes since 1990, farm and land management practices and biomass production. The spatial framework selected for national analysis is the Soil Landscapes of Canada, and the primary existing data sources are the Census of Agriculture, sample-derived yield estimates and satellite-based land cover products. These are supplemented with detailed, multi-season, multi-year satellite image interpretations conducted at an ecologically and statistically stratified sample of sites across the country. The use of these data in preparing an account of greenhouse gas sources and sinks identified a number of gaps and problems, and a brief outline of future work designed to improve the data inputs is presented. Key words: Kyoto reporting, data integration, land use and management, greenhouse gases, carbon sequestration
