Contexte et objectifs –
La conservation durable de la biodiversité requiert une bonne compréhension des causes de son déclin. Mis à part les activités humaines, les changements climatiques se révèlent comme la principale menace qui pèse sur la biodiversité au 21ème siècle. Notre étude vise à déterminer l’impact du changement climatique sur les Ptéridophytes au Togo.

Fonio (Digitaria exilis(Kippist)Stapf) and Bambara groundnut (Vigna subterranea(L.)Verdc.) are native crops grown at a small scale in Mali that have potential to support agricultural productivity under climate change. A community biodiversity management approach was explored in this study as a means to reinforce the cultivation of these crops by increasing farmers’ access to intraspecific diversity and developing capacities of community institutions for their management. The research involved six communities in Ségou and Sikasso regions.

Smallholder farmers who grow maize landraces face important challenges to preserve their seed biodiversity from one season to another. This study was carried out in the central highlands of Mexico to compare the effectiveness of two seed storage practices—specifically, polypropylene woven bags (farmers’ conventional practice) vs. hermetic containers—for minimizing seed losses and maintaining germination. Four Mexican landraces were stored for three and six months. Data on moisture content and kernel damage were collected at the beginning and the end of the storage period.

This work provides a preliminary inventory of West African Coccinellidae.
This was based on the West African Coccinellidae (WAC) specimens in the holdings of insect collections at the Laboratoire de Zoologie des Invertébrés Terrestres at the Institut Fondamental d’Afrique Noire Cheikh Anta Diop (IFAN), Senegal and the Biodiversity Center at the International Institute of Tropical Agriculture (IITAB), Benin.

The Enviro-Champs initiative was developed as a community driven, citizen science initiative in Mpophomeni township in Kwa-Zulu Natal (KZN), South Africa. Over time, the scope of work done and data collected by the Enviro-Champs has expanded. There is now recognition both locally and globally that the Enviro-Champs initiative shows great promise for national and global upscaling. However, several areas within the initiative remain where it could be improved, especially technologically.

There is a current need for better understanding the impact of nutrition-sensitive agriculture interventions. This study is based on a community-based participatory project that diversified diets of women and children by making use of local food biodiversity. This retrospective impact pathway analysis aims at explaining why and how impact was reached. Pathway analysis in nutrition-sensitive agriculture can provide valuable understanding on how and why dietary improvements have been achieved in an intervention.

To promote the sustainable use of native biodiversity, the Regional Government of Ucayali in Peru formed a Regional Technical Commission on BioTrade to develop a Regional Strategic Plan following an agroecological approach. The Alliance, together with the NGO Terra Nuova, supported the development of the strategy and its action plan. The plan aims to raise awareness on Amazonian native products, strengthen farmer organizations and institutions, and support local businesses.

Indigenous Peoples’ lands (IPL) cover at least 38 million km2 (28.1%) of the global terrestrial surface. These lands can be important for biodiversity conservation. Around 20.7% of IPL intersect areas protected by government (PAs). Many sites of importance for biodiversity within IPL could make a substantial but hitherto unquantified contribution to Global site-based conservation targets. Key Biodiversity Areas (KBAs) represent the largest global network of systematically identified sites of high importance for biodiversity.

A river basin – the breadbasket of millions – battered by floods just a few months earlier, slowly dries up; struck by climate change, over-abstraction of water and degradation of soils and land. As the river flow and reservoir levels fall, hydropower production declines. Farmers start to rely more heavily on groundwater, but access to energy for their irrigation wells is expensive. Many, especially women, are without access and a voice; others pump too much and ratchet up the water stress of the whole basin. Soils turn to dust, crops wilt, livestock and wildlife perish.

There is increasing recognition of the role of Indigenous and local knowledge systems in sustainable land use and conservation practices. However, the evidence base remains fragmented, while local knowledge remains marginalised in many national biodiversity strategies and development plans. This applies to the Tonga people of Zambia and Zimbabwe.

The convergence of the biodiversity and climate crises, widening of wealth inequality, and most recently the COVID-19 pandemic underscore the urgent need to mobilize change to secure sustainable futures. Centres of tropical biodiversity are a major focus of conservation efforts, delivered in predominantly site-level interventions often incorporating alternative-livelihood provision or poverty-alleviation components. Yet, a focus on site-level intervention is ill-equipped to address the disproportionate role of (often distant) wealth in biodiversity collapse.
