Land management and conservation have been considered the most important aspects of sustainable productivity in economically developing countries where land degradation is a major challenge. In Tanzania, both the government and international organizations have been promoting adoption of land management and conservation technologies (LMCTs) for a long time. This paper establishes the impact of three LMCTs – soil water conservation technologies and erosion control (SWCEC), organic and inorganic fertilizers – on maize crop yields in different rainfall zones, using national panel survey data. The study employs static panel models to analyse the two-period data sets for 2008-2009 and 2010-2011. The results indicate that adoption of LMCTs do contribute significantly to maize yield. The greatest effects of organic and SWCEC methods on crop yield were realized in low rainfall zones, while that of inorganic fertilizers was observed in high rainfall zones. These findings support previous cross-sectional data analyses, suggesting for policy makers that a blanket land management and conservation programme applied uniformly to all agro-ecological zones is not strategically beneficial. The advisability of a technology employed in a given zone should be supported by local knowledge and research findings culled from that particular area.

Protected areas (PAs) are under immense pressure to safeguard much of the world’s remaining biodiversity and can be strained by unpredicted events such as the COVID-19 pandemic. Understanding the extent of the pandemic on PA inputs, mechanisms, and conservation outcomes is critical for recovery and future planning to buffer against these types of events. We use survey and focus group data to quantify the impact of the pandemic on Mexico’s PA network and outline the pathways that led to conservation outcomes. On average, across 62 PAs, we find substantial changes in management capacity, monitoring, and tourism, and a slight increase in non-compliant activities. Our findings highlight the need to increase short-term relief efforts and long-term livelihood diversification initiatives for communities dependent on tourism, who were most vulnerable during the pandemic. Increased management support, including technical capacity and financial resources, could also better sustain management activities in future shocks.

Research during the late 20th and early 21st centuries found that traces of human intervention in vegetation in Southeast Asian and Australasian forests started extremely early, quite probably close to the first colonization of the region by modern people around or before 50,000 years ago. It also identified what may be insubstantial evidence for the translocation of economically important plants during the latest Pleistocene and Early Holocene. These activities may reflect early experiments with plants which evolved into agroforestry. Early in the Holocene, land management/food procurement systems, in which trees were a very significant component, seem to have developed over very extensive areas, often underpinned by dispersal of starchy plants, some of which seem to show domesticated morphologies, although the evidence for this is still relatively insubstantial. These land management/food procurement systems might be regarded as a sort of precursor to agroforestry. Similar systems were reported historically during early Western contact, and some agroforest systems survive to this day, although they are threatened in many places by expansion of other types of land use. The wide range of recorded agroforestry makes categorizing impacts problematical, but widespread disruption of vegetational succession across the region during the Holocene can perhaps be ascribed to agroforestry or similar land-management systems, and in more recent times impacts on biodiversity and geomorphological systems can be distinguished. Impacts of these early interventions in forests seem to have been variable and locally contingent, but what seem to have been agroforestry systems have persisted for millennia, suggesting that some may offer long-term sustainability.

<em>Abstract.</em>—Riparian and floodplain forests are vital components of landscapes. They are transitional zones (ecotones) between river and upland ecosystems where ecological processes occurring in riparian areas and floodplains connect and interact with those of rivers and streams. These forests are the major source of large wood for streams and rivers. Extensive loss of riparian and floodplain forests around the globe is evident from the dramatically reduced supply of large wood in rivers. Clearly, it is necessary to conserve and restore riparian forests to sustain a supply of wood for rivers. This chapter discusses river and land management practices that are designed to provide a continuous source of large wood for rivers and retain wood once it has entered the channel or floodplain. These management practices include conservation of intact riparian and floodplain forests, restoration of ecological processes necessary to sustain riparian forests in the long term, and management of riparian forests specifically to accelerate recruitment of large wood to rivers and streams.

AbstractIn 2008, the Carlsbad Field Office of the Bureau of Land Management (BLM) made a fundamental change in how they work with the energy industry in the Permian Basin of southeastern New Mexico, one of the nation's busiest “oil patches.” Through a collaborative effort that involved the Bureau of Land Management, the New Mexico State Historic Preservation Officer, the Advisory Council on Historic Preservation, the Mescalero Apache Tribe, and industry representatives, they developed and implemented the Permian Basin Memorandum of Agreement (MOA). This agreement allows energy development proponents to contribute funds to archaeological research in lieu of spending an equivalent amount of money on traditional archaeological field survey. The mitigation program governs how BLM addresses long-term damage and cumulative impacts to archaeological resources as new development proceeds in the Permian Basin MOA area. Now in its fifth year, the program has succeeded in key ways: industry has gained control over schedules and time, while archaeologists have gained control over where and how they do archaeology. Key lessons have been learned along the way: The funding mechanisms of the program work well, but doing archaeology through a collaborative working group takes a lot of time and energy.

Dynamic processes of seed germination, influenced by niche–climate interactions, underpin successful seedling establishment. For threatened species with niches restricted to specific landforms, such as Banded Ironstone Formations (BIF), understanding germination opportunities in relation to long-term rainfall patterns can be critical for management. We quantified germination profiles (germinating fraction and speed with varying dormancy states) from six taxonomically diverse threatened species that are endemic to BIF in Western Australia, and related this to historic rainfall patterns and events. The upper limit of the germination profiles (i.e. for dormancy-alleviated seed) was 1.2–60 times higher (germinating fraction; Gmax) and 1.1–4 times faster (T10) than the lower profile limit (i.e. dormancy not alleviated) in the physiologically dormant species studied (Tetratheca paynterae Alford subsp. paynterae and T. erubescens J.P.Bull; Ricinocarpos brevis R.J.F.Hend. &amp; Mollemans; Darwinia masonii C.A.Gardner; Lepidosperma gibsonii R.L.Barrett). Seeds of Banksia arborea (C.A.Gardner) A.R.Mast &amp; K.R.Thiele are non-dormant and had a germination profile similar to this upper limit. The minimum period of moisture required for germination was less than eight consecutive days and our simple moisture model, based on historic rainfall patterns for their localities, indicated that these periods have likely occurred 16 times in the last 100 years. We suggest that these BIF species are likely committing to germination during heightened rainfall periods, despite these periods being infrequent and irregular. Understanding the germination profiles of range-restricted species provides important insights into the environmental filters regulating recruitment and supports the development of more effective management and conservation approaches for protecting these species.
