This migration leads annually to resource use conflict and deadly attacks between migrating&nbsp; pastoralists and sedentary arable farmers. These conflicts have generated heated scholarly debates over the last few decades. Here, we provide an overview of the nexus between the farmer-herder crises, grassland management, and livestock production and argue for the establishment of irrigated pastures to increase forage production and quality and, thereby, reduce land-use conflicts. This recommendation is offered in place of the often-called-for transition to a ranching system for livestock production. We recommend an interdisciplinary approach to investigate the willingness of stakeholders in the livestock business to pay for fresh or conserved forage&nbsp; resources, as well as robust policies that could attract investment into the establishment, management, and sustainability of commercial forage production. </p> 2021-08-18T00:00:00+00:00 Copyright (c) https://www.ajol.info/index.php/ajrfs/article/view/212813 Topo-edaphic environment and forest plantation disturbance explain patterns of grassland species richness, composition and structure in an agro-ecological landscape, Maputaland, South Africa 2021-08-18T07:48:37+00:00 A.P. Starke allister.starke@gmail.com T.G. O’Connor allister.starke@gmail.com C.S. Everson allister.starke@gmail.com <p>Grasslands of the Maputaland coastal plain are biologically diverse and provide a variety of ecosystems services. Yet grasslands in this region are vulnerable to continuing development by plantation forestry that provides economic benefits to local communities. In order to provide a framework for land use that maintains grassland heterogeneity in complex agro-ecological systems, this paper characterises the main relations between grassland species composition, the physical environment and forestry plantation disturbance. Grassland species composition corresponded with landscape position and soil organic carbon. Grasslands occurring in infertile, elevated landscape positions were the most diverse having a greater richness of tufted graminoids, herbaceous forbs and geoxylic suffrutices than grassland occurring in low-lying dystrophic sites, which were dominated by rhizomatous and stoloniferous graminoids. Previously afforested grasslands (i.e. secondary grassland) were species poor, lacked keystone grasses, such as Themeda triandra, were dominated by a few species of rhizomatous or stoloniferous grasses and had been colonised by pioneer or ruderal forbs. Grassland species composition affects the provision of ecosystem services so to maintain a full complement of these attributes, grassland landscapes in Maputaland should comprise intact grasslands that cover both elevated and low-lying topographic positions. </p> 2021-08-18T00:00:00+00:00 Copyright (c) https://www.ajol.info/index.php/ajrfs/article/view/212815 Topo-edaphic environment and forestry plantation disturbance affect the distribution of grassland forage and non-forage resources, Maputaland, South Africa 2021-08-18T07:55:03+00:00 A.P. Starke allister.starke@gmail.com G. O’Connor allister.starke@gmail.com C.S. Everson allister.starke@gmail.com <p>Grasslands are integral to rural livelihoods in southern Africa, because they provide hydrological regulation services and a variety of plant resources, including livestock fodder, medicines, and food products. To ensure ongoing provision of these resources in rapidly developing rural landscapes, an understanding of the relationships between grassland species composition and ecosystem services is required. This study examines the provision of grassland forage and non-forage resources across five grassland types in relation to environmental determinants of site topography, soil conditions, and plantation-forestry disturbance. Grasslands characteristic of low-lying and fertile landscape positions were dominated by nutritious lawn grasses and therefore tended to complement rangeland practices, whereas grasslands associated with elevated areas or infertile conditions were diverse in species composition and consequently provided the majority of plant medicines, spiritual resources, fruit-beverage resources, oils, and craft materials. Secondary grassland, resulting from forestry plantation abandonment, had moderate forage potential and limited non-forage resources. Our results provide a simple framework for approaching grassland resource classification, grassland conservation and land use management on the Maputaland coastal plain. </p> 2021-08-18T00:00:00+00:00 Copyright (c) https://www.ajol.info/index.php/ajrfs/article/view/212817 Water uptake plasticity of savanna trees in encroached grassland: small trees match the mature trees 2021-08-18T08:20:51+00:00 Séraphine Grellier seraphine.grellier@univ-tours.fr Jean-Louis Janeau seraphine.grellier@univ-tours.fr Patricia Richard seraphine.grellier@univ-tours.fr Nicolas Florsch seraphine.grellier@univ-tours.fr David Ward seraphine.grellier@univ-tours.fr Thierry Bariac seraphine.grellier@univ-tours.fr Simon Lorentz seraphine.grellier@univ-tours.fr <p>Processes linked to woody plant encroachment in grassland are still not well understood, especially the interactions between trees and soil water availability. Our aim was to study the depth of water uptake by trees in grassland and its controlling factors. We studied water uptake in Vachellia sieberiana trees (hereafter called ‘acacias’) in a humid grassland of South Africa. We especially studied the effect of size classes of acacias and their position in the catena on water potential (ψ) of acacia leaves and water uptake depth of acacias across seasons, as inferred from isotope δ18O values of soil and stem water samples. Acacias were more water&nbsp; stressed in February (wet season) with the most negative water potentials. Taller acacias (&gt;3 m height) were more water-stressed (ψ ± SD = −1.62 ± 0.81 MPA) than smaller acacias (&lt;1 m height) (ψ ± SD = −1.32 ± 0.80 MPA). In September (end of dry season), all tree size classes uptake water equally in A and B soil horizons. In February (middle of the wet season), tall, medium and even small trees favoured the B horizon. Small trees had similar plasticity in water uptake to taller trees and could modify depth of water uptake between seasons. This process could increase their probability of becoming adults, and may favour tree encroachment in grasslands.</p> 2021-08-18T00:00:00+00:00 Copyright (c) https://www.ajol.info/index.php/ajrfs/article/view/212819 Primer of Ecological Restoration - Karen D Holl, published in cooperation with the Society for Ecological Restoration 2021-08-18T08:15:17+00:00 K.P.
