Land supplies multiple goods and services vital to humans and the environment. In the last decades, increasing evidence of growing land degradation are made apparent. A limited and depleting resource base, the reliance on climate-sensitive sectors and its large population, make South Asia highly vulnerable to climate change. Observed changes in climate include increases in temperature and increased monsoon variability and rainfall pattern leading to drought and flooding. Projected changes include increasing temperatures, rising sea levels, increasing cyclonic activity and higher variability of rainfall, all having enormous impacts on farming communities. At the same time, the region is rich in traditional agricultural knowledge (TAK), specialized in managing local agroecosystems to ensure food availability, tackling climatic risks and other ecological uncertainties. Particularly relevant is TAK related to land management to preserve soil fertility and avoid soil erosion. Ethnographic research is a valuable source of TAK, although this is rarely analysed with a climate change perspective. Based on a qualitative systematic review, and an expert's on-line survey, in this paper we review land management TAK and assess its potential for climate change adaptation. The review shows there is a vast amount of untapped TAK ethnographic research with potential for climate change adaptation.

In the context of nutritional disaffection with a dominant food and agricultural system and the social questioning of everyday nutritional habits, we studied what Eating Well means to people and what role organic food plays in their lives. We conducted 11 discussion groups that were carried out in Andalusia, Spain; participants had different socio-demographic characteristics—they lived in either rural or urban areas, had different purchasing channels, and practiced varying degrees of organic food consumption. The investigation revealed (1) the motives and limitations for the consumption of organic foods, as perceived by the consumers of organic foods, and (2) the everyday strategies practiced to overcome these limitations. In both cases, this research transcends the classical analyses focused on the price of a product, when proposing a framework for alternative strategies that are based on the ordinary knowledge and practices of the consumers, by looking at consumption through an integrated lens that is rooted in the notion of what consumers consider to be Eating Well. This study shows that Eating Well—according to the criteria of the consumers and the implemented strategies—breaks from the dichotomous or exclusive focus on economic or ideological motives, and revalues feminine and rural knowledge and practices, for a comprehensive management of nutrition.

Climate variations are considered one of several interacting factors affecting food security. Specifically, in the Indo-Gangetic Plains, increased exposure to droughts and floods are expected. Local traditional knowledge in agriculture (LTKA) is proposed in this article as valid knowledge to ensure food availability under climate change, given its long experience in dealing with climate variability. Focused on water strategies, we have conducted a literature review on LTKA practices in the Indo-Gangetic Plains complemented with a questionnaire of experts to identify LTKA-based practices that might be useful in climate-change driven water scenarios. The practices identified are categorized as a) water harvesting and recycling; b) local irrigation systems; and c) and maintenance, conservation, and water allocation. We found that a) despite acknowledging the potential of LTKA to face floods and droughts, very few studies explicitly make the link between LTKA and climate change; and b) LTKA in water management heavily relays on social norms and local institutions and, thus, any attempts to replicate it need to consider this. We conclude that agroecology can help to promote these practices since it emphasizes the collective management from below as the main approach for the design of sustainable agroecosystems and, thus, include local institutions as an essential strategy for adaptation.

[EN] Cocoa is one of the most important crops in Ecuador, especially in the Ecuadorian Amazon, where >60,000 ha are dedicated to cocoa; 48,600 ha in production in 2021. Most of the cocoa area (82 %) is managed by smallholders with <10 ha under cultivation. Despite the socioeconomic and environmental importance of these systems, there are no previous studies that provide an integrated view of the energy metabolism and economic viability of different smallholder management styles. Consequently, the objective of this work is twofold: a) to estimate the aggregate energy and economic metabolism of small cocoa producers (< 10 ha) in the Ecuadorian Amazon and b) to investigate the existing differences in the technical-economic management styles of the crop. To this end, primary data were collected from a statistically representative sample of cocoa-growing areas distributed among 279 producers in 86 communities in the region, using the life cycle assessment (LCA) methodology and a cost-benefit analysis associated with management. Our data show that most smallholder farmers produce cocoa in low-input diversified agroforest system with a high share of unpaid family labor. At the Amazon level, smallholder farmers (< 10 ha) produced 16.9 million tons of food for the market with a nonrenewable cumulative energy demand (NR CED) of 53.8 TJ (1343 MJ/ha), a carbon footprint (CF) of 8.16 Mt. CO2-eq. (203.9 kg CO2-eq/ha), and a net margin of 19.07 million $ (476.8 $/ha). On average, cocoa yields were estimated at 288 kg/ha, resulting in a NR CED and carbon footprint (CF) per kg of cocoa of 4.18 MJ and 0.98 kg CO2-eq. Despite its apparent homogeneity, three distinct styles of crop management were identified by a cluster analysis. The results suggest that farms with good organic/agroecological management can have a similar income generating capacity to the more intensive conventional farms evaluated, but with better environmental outcomes. Consequently, the paper finally discusses the

[EN] Ecuador is the third largest cacao exporter in the world. Up to 10 % of Ecuador's cacao production is grown in the Amazon region, mostly under conventional (CA) and organic (OA) agroforestry systems. Despite the importance of cacao in this area, no previous studies on its environmental impact and economic viability have yet been carried out. The main objective of this research is to fill this gap and, more specifically, perform a comparative analysis between CA and OA systems. For this purpose, primary information was gathered from 90 farms (44 conventional and 46 organic ones) that implement land management practices. The environmental performance of cacao production was assessed using a life cycle analysis methodology, with a cradle-to-farm gate approach. Up to twelve impact categories and five environmental and monetary efficiency indicators were estimated based on three functional units (1 kg of cacao, 1 kg of output sold, and 1 ha). Additionally, an economic viability analysis was performed, focused on profitability. The results show that organic management allows to reduce the environmental impact in all the analyzed categories, except for the land footprint, and improved the environmental and economic efficiency of agroforestry systems. The economic analysis shows no statistically significant differences between CA and OA profitability (net margin), which can be improved by selling co-products. Despite the low environmental impact of both types of system, economic profitability is certainly one of the weaknesses of cacao production in the Ecuadorian Amazon region. This study contributes to develop technical, production-related and political actions that could improve the economic cacao production situation without jeopardizing the environmental benefit obtained by these systems.
