Within the multidisciplinary framework of historical ecology, in this study plant morphology, oral history, and soil analyses are combined with phytoliths to reconstruct shifts in management and environment of historical and living olive agroecosystems on the island of Sicily (Italy). The use of phytoliths in the study of historical agroecosystems is still a developing field. We present the collaborative work done on three historical olive agroecosystems (Bosco Pisano, a wild olive wood; Cozzo del Lampo, a Mediterranean olive orchard; Malìa, remnant of past agroforestry), where we have collected and analyzed phytolith assemblages to trace correlations between environmental dynamics and (agri)culture, as unfolding over the latest six millennia. We demonstrate that the cumulative ecological legacies in historical agroecosystems are traceable through phytolith analyses. Bosco Pisano allows for a calibration of the tree cover density, based on phytolith evidence. Meanwhile, Cozzo del Lampo and Malìa have evolved from a shrubland-type of environment to fruit gardens and open grasslands, with establishment of olive trees in between as key vegetation elements. Both these examples show the longevity of combined land uses, especially the grazing adapted olive cultivation in Malìa. In gaining clues on clear variations in land use, as abandonment and intensification, our results demonstrate that phytoliths can shed light also in local past intercultural exchange of knowledge. The integrated methodology presented here allows to appreciate how the biological and cultural diversity in historical agroecosystems has shaped their current state and inspires present-future management.

Mozambique has undocumented forest patches that are cultural landscapes and locally protected as heritage sites. Using the case of Inhambane Province, in this paper, we present the status and purposes of forest patches protected by local communities and discuss threats working against local protection. Findings point out that these heritage forests are reservoirs for biodiversity conservation and the local system of conservation is effective, but there are challenges local custodians face to safeguard heritage forests, ranging from illegal logging, misrecognition of customary protection and lack of legislation enforcement. We argue that the existence of heritage forests requires collaboration between entities dealing with forests, heritage and conservation. We suggest strategies to increase protection in the Inhambane Province and the Mozambique context. This will support local institutions in the protection of heritage forests, as biodiversity reservoirs and in keeping heritage practices and the customary protection of heritage forests alive.

Black carbon is a paleofire proxy that has been measured from glacial ice, snow, soils and lake sediments, though relatively few comparisons have been made with other fire indicators in sedimentary geoarchives. Microscopic charcoal, quantified from palynological microscope slides and macroscopic charcoal, quantified from wet-sieved deposits, are the most commonly applied methods for paleofire interpretation of Quaternary sediments. This research explores the down-profile patterns across three paleofire proxies (refractory black carbon, microscopic and macroscopic charcoal) and potential paleofire interpretations from a sediment core dating to the last centuries from Speke Gulf, Lake Victoria, and a young soil profile from a kopje located in the surrounding watershed in Serengeti National Park, Tanzania. The results of three paleofire metrics show similar trends within each site, with a positive trend across all metrics and increasing variability with increased measurement values (heteroscedastic). Notably, refractory black carbon (rBC) concentrations are two orders of magnitude higher in lake sediment samples compared to soil samples. rBC is positively correlated with both microscopic and macroscopic charcoal values and the overall profile patterns down the sediment core are similar, with the exception of the rBC increases from 2.5 to 0 cm depth that may result from increased fossil fuel combustion. The Speke Gulf rBC measurements are in an intermediate range between those published from glacial ice and other lake sediments. New rBC records from different ecosystems and temporal scales will provide paleofire insights and potential to interpret source areas and depositional patterns. The exploration of soil archives offers the potential to exploit semi-arid ecosystems and archaeological sites that have no nearby traditional paleoenvironmental study site targets.

The analysis of fossil pollen from sediments is used to understand past vegetation and land cover variability. The observations of multiporate Poaceae pollen from sediments have received little attention in the literature and causes and rates of occurrence have few estimates, and the rates observed in the sediments are much lower than estimates observed from modern plants in Asia. Pollen analysis of the uppermost sediments from Speke Gulf, Lake Victoria, eastern Africa, showed relative abundances of Poaceae between 65 and 75% during the past centuries. A total of 19 of the ∼11,000 Poaceae pollen grains observed had conspicuous morphological variations and were documented. More consistent presence of abnormal grains occurred since the mid twentieth century, at the same time of increased anthropogenic environmental stressors. Multiporate pollen grains of Poaceae have been previously observed in Asia, South America, and northern Africa, predominantly in the Panicoideae subfamily. Morphological variations may present an added challenge for automated pollen identification techniques and descriptions of fossil pollen.

This study was undertaken to address the question on anthropogenic landscape modification and how to use such signals within palynology. Pollen, spores, and microscopic charcoal from Lake Dalsträsk in the northern Åland Islands are analyzed, covering the period from 741 BCE (Late Bronze Age) to the early twentieth century. Percentage and influx data are compared as a means of disentangling different land use practices. The results of the palynological analysis are further explored through correlation analysis of influx data and Relative Pollen Productivity (RPP) values. Our findings confirm the presence of modest cereal cultivation and grazing activities from the beginning of the Late Bronze Age a hypothesis that has previously been debated. The study also shows variations in land use after the Bronze Age, with an increase in farming from around 398 CE (Migration Period) and an intensification of grazing activities around 823 CE (Viking Age). Our study shows how land use practices have shifted over the centuries and how these shifts have modified taxa composition. Commonly used 'anthropogenic indicator' pollen taxa show weak or indirect correlations with cereal cultivation and grazing, while some taxa display positive correlations. Our results point to the need to refine the use of anthropogenic taxa in a local context to better elucidate small-scale land use.

Phytoliths can be used to reconstruct human-nature dynamics over the long term (from decennial to centennial and millennial time scales) and may capture activities that cannot be reconstructed through other proxies. Phytoliths consist of fossil biogenic silica (BSi), formed in plant organs and then released into the soil with plant decay. When working in environmental contexts where the phytolith signal is highly diluted, as is the case in environments with a long history of land use, animal-plant interactions and open woody environments, the extraction of phytoliths remains a challenge. To address this issue, we developed an efficient method for the extraction of biogenic silica (BSi) from sediments and soils of contexts characterised by the long-term human and animal presence and disturbance, such as remnants of old agroforestry systems.The method we developed has a number of advantages, including:

• An easy and time-efficient methodology to perform (with an overall processing time of 1.5/2 days for a batch of 16 samples)
• An extraction method free from dangerous chemicals
• A method amenable to non-experts without a prior background in lab extraction procedures.

The discussion of the transition to farming in southern Africa and the formation of Early Iron Age society, referred to in Mozambican archaeology as the Early Farming Communities (EFC), is complicated by the lack of surveys in key areas of intensive contacts. This article presents the results of excavations at the EFC site Chicumbane in the eastern lower Limpopo Valley, dated 500–800 AD. The variation of ceramic styles in terms of decoration and shape suggests predominantly interior influences (Gokomere and Zhizo facies), but there are also decoration elements similar to what is found on the coast. A wide variety of ceramic technologies were used in terms of clay sources, temper, and ways of building the pot. Here, we reconstruct possible social interactions based on these differences. Together with the other artifact categories, such as slag, metal, and shell beads, the results show some aspects of regional interactions among Early Farming Communities. The combined ceramic analyses suggest a mix of traditions by female potters who, through marriage, moved between regions, bringing new ways of decorating, tempering, and building pots.

Local comparisons of effects, responses and mitigations to the Covid-19 pandemic are of vital importance inbuilding a sustainable tourism. This is particularly the case for conservancies in Africa which is largely dependent on international tourism. Qualitative interviews were carried out in the Kenya Maasai Mara WildlifeConservancies Association (MMWCA)with landowners, lodge managers and staff, tourism operators, community organisations and NGOs between January and May 2021. The MMWCA is an important case study asconservancies pay lease payments to more than 14,528 landowners through tourism revenues. The results showhow partner conservancies took different paths in securing payments of leases and salaries by rotating staff,attracting international funding and by targeting domestic tourism. Meanwhile, landowners experimented withalternative economic activities such as cattle herding and diary production. The study shows the strength ofMMWCA as a stakeholder partnership to proactively design measures including renegotiation of leasepayments, in soliciting external funding and in re-distributing funding. The positive role of domestic tourismis also stressed. The pandemic brought to the forefront discussions on equity and benefit sharing and on thesustainability of the model itself. Recommendations are given to strengthen possibilities for alternative incomessources and for a diversification of strategies of the MMWCA partners, including the need to stimulate domestictourism as a parallel source of income. These recommendations are also relevant to conservation areas acrossthe African continent

Large uncertainties still exist about the long-term mechanisms influencing the hydroclimate variability of southeast Africa where proxy data and model simulations indicate rainfall dipoles between subtropical and tropical areas. The topography of Madagascar, located off the southeastern coast of Africa, modulates these dipoles while its climate is influenced by the position of the Intertropical Convergence Zone (ITCZ) and the Subtropical High as well as the sea surface temperature (SST) of SW Indian Ocean. The island can thus be considered a key location for the understanding of the tropical SE African climatic variability and the interplay between atmospheric patterns. However, the scarcity of continuous records from Madagascar has made the evolution of regional late Quaternary climate and its driving mechanisms difficult to assess. Here, we present a 26-kyr record of the deuterium/hydrogen isotope ratio (5D) of biomarkers (n-alkanes) from the central eastern part of the island at Antananarivo at around 1250 m a.s.l. Preliminary summary pollen data are also presented as a comparison. The 5D profiles of aquatic plant and terrestrial plant-derived n-alkanes generally exhibit similar trends implying that they all record changes in the isotope composition of source water, namely meteoric water that recharges soil and lake waters. In this tropical region, the 5D variability of precipitation is mainly influenced by the amount effect reflecting the intensity of precipitation associated with the monsoon. We observe: (i) stable and wet conditions during the Last Glacial Maximum, (ii) drier conditions from 18.5 to 15 ka (ka before present) during the Heinrich Stadial 1 (iii) high humidity after 15 ka culminating at the Younger Dryas (YD), (iv) drier conditions from 11.7 ka to 8.2 ka, (v) a return to humid climate until 2.8 ka, and (vi) an arid phase followed by increased wetness after 0.9 ka, although the record is likely influenced by human-induced vegetation changes the last 1.2 ka. This climate signal is similar to other records from the Mozambique Channel but opposite to records from the East African mainland and the subtropical southern Africa, especially between 20 and 25 degrees S. Although there is a good correspondence of our record with insolation- driven migrations of ITCZ during the LGM and the early Holocene, the dipoles are largely consistent with the modern rainfall anomaly and are best explained by the interlinked effects of the SST changes and the variability of the Mozambique Channel Trough.

Protected Areas (PAs) are important wildlife refuges and act as climate change buffers, but they may impact human livelihoods, particularly engendering a high risk of negative human -wildlife interactions (HWI). Understanding synergies and tradeoffs among the drivers of overall human vulnerability within PAs is needed to ensure good outcomes for conservation and human wellbeing. We examined how climate variability, HWI, and socio-demographics affect livelihood vulnerability across three PAs in Mozambique, Southeast Africa. We used structured questionnaires to obtain information on livelihood vulnerability and socialecological context -specific variables. We applied principal component analysis to understand synergies and trade-offs between the dimensions of vulnerability and linear models to test the effect of social -ecological drivers on vulnerability. We show that households are mostly vulnerable within PAs due to exposure to climate variability and to HWI, and their low capacity to employ livelihood strategies or to have a strong social network. Furthermore, we show that vulnerability to HWI and climate variability increases with distance to strict protection areas within the PAs and distance to rivers, which implies that proximity to strict protection areas and rivers within PAs still promotes better livelihood conditions than elsewhere. On the other hand, we also found that lower access to infrastructure and other livelihood assets enhances vulnerability, which reflects a trade-off within PAs that potentially limits the benefits of socially inclusive conservation. Our results show that the impacts of PAs, HWI, and climate on community vulnerability should not be viewed in isolation, but instead, conservation and livelihood improvement strategies should reflect their interconnectedness. Although livelihood vulnerability appears to be shaped by these general effects of PAs, it is important also to consider the local PA context when addressing or mitigating livelihood vulnerability in and around them.
