Abstract Resolving ecological-economic trade-offs between biodiversity and yields is a key challenge when addressing the crisis in tropical agricultural landscapes. Here, we focused on relation seven different taxa (trees, herbaceous plants, birds, amphibians, reptiles, butterflies, ants) vanilla agroforests Madagascar. Agroforests established forests supported overall 23% fewer species 47% endemic than old-growth forests, 14% forest fragments. In contrast, fallows had 12% more 38% fallows....
Significance Finding entry points where policy has strong leverage to transform land systems for people and nature is pivotal. We develop an innovative framework identify evaluate such along land-use trajectories that account path dependency. Applied the biodiversity hotspot Madagascar, reveals three points: Two are associated with trade-offs between biodiversity, ecosystem services, agricultural productivity, while third entails cobenefits. Swift action required, as dependency caused by...
After the severe droughts in 1970s and 1980s, subsequent debates about desertification, analyses of satellite images reveal that West African Sahel has become greener again. In this paper we report a study on changes tree cover species composition three village landscapes northern Burkina Faso, based combination methods: density change detection using aerial photos images, inventory including size class distribution analysis, interviews with local farmers woody vegetation changes. Our...
Enduring sustainability challenges requires a new model of collective leadership that embraces critical reflection, inclusivity and care. Leadership collectives can support move in academia from metrics to merits, focus on career care, enact shift disciplinary inter- trans-disciplinary research. Academic organisations need reorient their training programs, work ethics reward systems encourage excellence allow space for future leaders develop radically re-imagined vision how lead as with care...
Abstract The northeastern SAVA region of Madagascar is the largest vanilla producing area in world and flourishing due to a large global demand for natural vanilla. Although general socio-economic situation has regionally improved because high prices, little known about nutritional status local farmers. We used 12-month longitudinal food survey analyze security, consumption nutrient intake farming households ( n = 140). Food data was complemented with baseline, agro-economic, field-plot...

Food value chains (VC) are an integral part of food systems, and programs remain central in the work development agencies. Despite their popularity among donors attempts to tackle nutrition security, poverty alleviation environmental sustainability, chain interventions at crossroads. The ongoing system crisis has ultimately put a square emphasis on as nexus issue. objective this paper is review history conceptual basics behind VC suggest changes way designed implemented order face current...
The coastal area of the Mahafaly Plateau in southwestern Madagascar is prone to droughts, as well other environmental risks, resulting frequent crop failures, famines, and extreme poverty. Thus, identification potential complementary livelihood sources has been identified a crucial step for sustainable development region. In this contribution, we assess prickly pear seed oil production an income alternative local communities. pears are cacti genus Opuntia Mill. they highly abundant region,...

The SAVA region, located in north-eastern Madagascar, is a global hotspot of vanilla production. Here, soaring prices over the past 7 years, so-called "vanilla boom", improved socioeconomic situation farming population, which may change dietary patterns towards higher meat consumption and offer an opportunity for regional livestock producers. This paper therefore investigates if boom opened new market opportunities to local stakeholders by targeting 81 producers, 23 butchers, 34 retailers...
The SAVA region in northeastern Madagascar is the largest vanilla producing area globally. Here, we investigated role of animal husbandry (AH) for income diversification small-scale farmers. To do this, 300 household heads were interviewed about livestock ownership, management and marketing. This information was complemented by data from 1800 households (HHs) on involvement production (VP) AH. Throughout region, 83 % HHs produced 84 kept livestock. Chicken-keeping (72 %) most prominent,...
