“…Mitten crab farming practices incorporate improved traditional practices making it environment-friendly overall with minimal TN, TP, COD and TSS levels in effluents compared to other aquaculture species (Cai et al 2012a). Environmental friendliness of farming practices is known to be a key to sustainability for all forms of primary production and a paradigm that is being increasingly acknowledged as a necessity for meeting the food demands for an increasing population (Charles et al 2015;Chartres and Noble 2015;Poppy et al 2015).…”

Results of a survey of 156 Chinese mitten crab (Eriocheir sinensis) grow-out farms around Hongze Lake (118.48-118.72°E; 33.36-33.38°N) are reported. Area farmed has remained relatively unchanged but production (59 932 t in 2012) increased steadily over the last 7 years, indicative of the viability and sustainability of the farming system that has gradually replaced intensive Chinese major carp polyculture around Hongze Lake. Results showed that production range was 135-2400 kg ha -1 cycle -1 (mean 1144 ± 34). Crab yields correlated linearly to stocking density and conformed to a normal distribution curve, with 66.7 % of farms yielding 900 kg ha -1 cycle -1 or more. Yield was negatively correlated to pond size and capture size (p\0.01), and farms with macrophyte coverage rate lower than 30 % of water surface were significantly (p\0.05) lower than those exceeding 30 %.

“…An individual or household cannot possibly be considered food secure if they have current access to adequate food to meet their immediate needs, while the natural capital that would provide for future needs is simultaneously being depleted (Sunderland, 2011). The sustainability dimension is thus an imperative component of the stability pillar, but is often neglected in the rush for short-term solutions (Poppy, Jepson, Pickett, & Birkett, 2014), potentially leading to a 'tragedy of the commons' situation (see Hardin, 1968). Failure to address the environmental and natural resource impacts will almost certainly hamper food supply, and thus also food security.…”

Wild meat or 'bushmeat' has long served as a principal source of protein and a key contributor to the food security of millions of people across the developing world, most notably in Africa, Latin America and Asia.More recently, however, growing human populations, technological elaborations and the emergence of a booming commercial bushmeat trade have culminated in unprecedented harvest rates and the consequent decline of numerous wildlife populations. Most research efforts aimed at tackling this problem to date have been rooted in the biological disciplines, focused on quantifying the trade and measuring its level of destruction on wildlife and ecosystems. Comparatively little effort, on the other hand, has been expended on illuminating the role of bushmeat in human livelihoods and in providing alternative sources of food and income, as well as the infrastructure to make these feasible. This paper aims to shift the focus to the human dimension, emphasising the true contributions of bushmeat to food security, nutrition and wellbeing, while balancing this perspective by considering the far-reaching impacts of overexploitation. What emerges from this synthesis is that bushmeat management will ultimately depend on understanding and working with people, with any approaches focused too narrowly on biodiversity preservation running the risk of failure in the long term. If wildlife is to survive and be utilised in the future, there is undoubtedly a need to relax adherence to unswerving biocentric or anthropocentric convictions, to appreciate the necessity for certain trade-offs and to develop integrated and flexible approaches that reconcile the requirements of both the animals and the people.

“…But there has also been growing concern that farming practices themselves, both in extensive food crop production systems (found widely in Sub-Saharan Africa) and intensifying systems (common in South Asia) are exacerbating biotic and abiotic constraints on food production through negative impacts on the environment (Poppy et al 2014;Dogliotti et al 2014;Chartres and Noble 2015). Common examples include environmental degradation through agriculture-related deforestation, soil erosion, nutrient mining, water depletion, soil/water/air pollution, biodiversity loss, and climate change; all of which threaten the long-term viability of agriculture and agro-ecosystems (Cassman et al 2003;Keating et al 2010;Phalan et al 2011;Pretty et al 2011;Tilman et al 2011;Chartres and Noble 2015).…”

Environmental impacts and constraints associated with the production of major food crops in Sub-Saharan Africa and South Asia

Many environmental factors constrain the production of major food crops in Sub-Saharan Africa and South Asia. At the same time, these food production systems themselves have a range of negative impacts on the environment. In this paper we review the published literature and assess the depth of recent research (since 2000) on crop x environment interactions for rice, maize, sorghum/millets, sweetpotato/yam and cassava in these two regions. We summarize current
