The carbon footprint of young-beef cattle finishing systems in the Eastern Plains of the Orinoco River Basin of Colombia

Dezembro, 2022
Colombia

Introduction: Previous research has shown increased productivity amongst sown grass pastures compared to native savanna pastures by year-round grazing for fattening of adult and young Brahman (Bos indicus)-bred cattle in the well-drained native savanna ecosystem of the Colombian Orinoquía. But there is limited information on the carbon footprint (CF) of commercial young-Brahman heifers and steers reared throughout life on well-managed Brachiaria decumbens Stapf pastures.

Seeds that give revisited: Participatory plant breeding and rural revitilization

Dezembro, 2022
Global

In 2003, the International Development Research Centre (IDRC) of Canada published “Seed that give. Participatory plant breeding,” synthesizing the achievements and lessons learned of the first 10 (pioneering) years of participatory plant breeding (PPB), a concept first tabled at an international workshop in Wageningen, the Netherlands, in 1994. IDRC was one of the early and most fervent supporters of PPB. See: https://publications.gc.ca/site/eng/9.648982/publication.html

Participatory action research, social networks, and gender influence soil fertility management in Tanzania

Dezembro, 2022
Global

Transformation of knowledge systems and fostering learning among smallholder farmers such as through participatory action research (PAR) is key to agricultural growth in rural sub-Saharan Africa. We investigate how PAR influences uptake/use of integrated soil fertility management (ISFM) while accounting for gendered, bonding and bridging social capital. Stratified by engagement in a mother-baby PAR and by resource endowments, 607 smallholder farmers were sampled from northern Tanzania.

Influence of rangeland protection and seasonal grazing on aboveground vegetation, forage quality and weight gain of small ruminants — a study in Thar Desert, Pakistan

Dezembro, 2022
Pakistan

The Thar Desert, Sindh, Pakistan is characterized by low productivity. Besides, economy is based on agriculture, livestock and mining, nevertheless, livestock graze freely on public and private land. The aim of this research was to determine biomass production and to evaluate the effects of continuous and seasonal grazing on protected and unprotected plots. A 45 ha protected rangeland area of Hurrabad in the Umerkot Thar desert was selected and divided into three blocks of 15 ha each. Blocks of the same size were also established in unprotected area.

Introgression of the QTL qSB11-1TT conferring sheath blight resistance in rice (Oryza sativa) into an elite variety, UKMRC 2, and evaluation of its backcross-derived plants

Dezembro, 2022
Global

Introduction: Sheath blight (SB) is the most damaging fungal disease in rice caused by a soil-borne pathogenic fungus, Rhizoctonia solani Kuhn (R. solani). The disease resistance in rice is a complex quantitative trait controlled by a few major genes. UKMRC2 is a newly developed elite rice variety that possesses high yield potential but is susceptible to sheath blight disease indicating a huge risk of varietal promotion, mass cultivation, and large-scale adoption. The aim of our present study was the development of varietal resistance against R.

Sustaining adaptive collaborative management processes: Challenges and opportunities from Mafungautsi State Forest, Gokwe, Zimbabwe

Dezembro, 2022
Zimbabwe

An adaptive collaborative management (ACM) project was implemented in Mafungautsi State Forest, in the Gokwe South District of Zimbabwe between 1999 and 2006. By 2005, significant collaborative momentum between local resource users and officialdom at various levels had been created. Over the same period, Zimbabwe experienced unprecedented changes associated with its land reforms, profoundly impacting natural resource management.

Local working collections as the foundation for an integrative conservation of Theobroma cacao L. in Latin America

Dezembro, 2022
Global

The intraspecific diversity of cacao has traditionally been preserved in genebanks. However, these establishments face various challenges, notably insufficient funding, accession redundancy, misidentification and lack of wild cacao population samples. In natural environments, it is expected that unknown varieties of cacao may still be found, but wild populations of cacao
