Abstract Agricultural commodity expansion into natural and semi‐natural ecosystems in Asia is a multi‐dimensional sustainability challenge posing threat to human capital. At the symposium pertaining agricultural landscapes organized at 59th meeting of Association for Tropical Biology Conservation, we aimed identify key aspects that require further attention address negative impacts commodity‐driven Asian tropics. Using combination insights obtained both from participants' research those developed organically symposium, identified five themes: (1) Robust land use suitability assessments determine viability or other competing demands on productive given landscapes; (2) need plot‐level studies soil biodiversity ecological functions crops; (3) Irrigation crops with blue green water evaluating co‐dependent drivers outcomes; (4) an improved understanding local producer motivations supply chains (5) analysis co‐benefits, trade‐offs synergies agro‐commodity systems. These themes include various steps involved expansion, right selection crop patterns post‐harvest value chain. are inter‐connected span across multiple regional spatial scales tropical but hold relevance elsewhere too.

Purpose This study aims to replace petroleum-based lubricating oils with sustainable biomaterials, addressing issues associated existing alternatives, such as poor performance, high cost and limited availability. Design/methodology/approach The transformation of agricultural waste cardanol, a nonedible vegetable oil that is abundantly available, into green cardanyl acetate (CA) biolubricating ester oil. potential CA base stock for lubricants validated by assessing its lubrication performance. Findings exhibited higher viscosity index, flash point thermal stability than commercially available mineral-based (CTL3, coal-to-liquid) synthetic (PAO2, poly-alpha-olefin) lubricant stocks. Moreover, exhibits excellent anticorrosivity properties well PAO2 CTL3. tribological were evaluated, the results show smaller average wear scar diameter (WSD) 0.54 mm (0.85 mm) CTL3 (0.90 mm). In extreme pressure tests, acylated demonstrated highest last nonseizure load capacity at 510 N, outperforming commercial (491 N) (412 N). All demonstrate displays an series properties. Originality/value novelty this work lies in utilization renewable waste, cashew nut shell liquid, produce high-value biolubricant alternative fossil-based lubricants. nature, low cost, large-scale availability raw materials pave new path production application biolubricants, showcasing immense converting products.

West Africa is exceptionally biodiverse, yet its wildlife remains largely understudied despite the rapid and ongoing land-use changes. Large swaths of Guinea-Bissau's landscape were historically characterised by native forest-savannah mosaics. However, key areas savannah habitats have been converted to rice agroecosystems forests are being transformed into cashew monocultures at unprecedented rates. Amphibians reptiles comprise some most threatened species human-induced habitat change not as studied other vertebrate terrestrial taxa. Here, we provide two comprehensive datasets on amphibians (classes Testudines Squamata) from northern Guinea-Bissau: (1) a standardised survey dataset (encompassing sampling events occurrences) in forest fragments, orchards paddies (2) an opportunistic reporting occurrences across entire study area. Standardised surveys carried 21 sites, seven each type, while include all records. For surveys, total 703 amphibian 265 reptile (class encounters reported, corresponding nine 13 taxa, respectively.

Abstract Agricultural induced land‐use change comprises a key driver of biodiversity loss across tropical forests. Guinea‐Bissau, among Afrotropical West Africa, was formerly occupied by native forest‐savanna mosaics. While savannas have long given place to traditional rice agroecosystems, forests are now being transformed into cashew monocultures at unprecedented rates. The ecological impact such rapid is largely unknown. Here, we examined how rarefied species richness, encounters, and composition amphibians reptiles varied forest remnants, orchards, paddies in northern Guinea‐Bissau. To do so, visual encounter surveys were carried 21 standardized sampling sites, seven each habitat type. A total 703 amphibian 266 reptile encounters recorded from nine 14 taxa, respectively. results show class‐specific responses Amphibian richness similar types, but held more distinct compared remnants. Reptile lower than orchards had the most different Overall, our not support expected detrimental impacts expansion, which might be due still high heterogeneity types within landscape. Rice proved particularly important for amphibians, open‐habitat reptiles, boosting landscape‐scale diversity. In face eminent conversion, maintaining heterogeneous landscapes, including persistence both remnants paddies, critical minimize Africa.
