Genetic dissection of plant height in spring wheat from Pakistan using genome-wide SNPs and allele-specific Rht markers by Suleman, Hafiz Muhammad, Qayyum, Humaira, ur Rehman, Sana, Majeed, Khawar, Mukhtar, Misbah, Zulfiqar, Saima, Mahmood, Zahid, Aziz, Abdul, Fayyaz, Muhammad, Mehvish, Ambreen, Cao, Shuanghe, Rasheed, Awais, Zhonghu, He

“…The use of alternate dwarfing alleles to reduce PH can increase the genetic base of wheat cultivars by reducing selection pressure on the Rht-B1b/Rht-D1b haplotype and can lead to the development of wheat cultivars with improved characteristics such as reduced lodging risk, increased resource allocation to grain, improved harvest efficiency, enhanced crop stability, and adaptability.…”

Climate change impacts on family farming systems and local adaptation strategies in Chiapas and the Yucatán Peninsula by Peña, Meliza, Schröder, Lea, Euler, Michael

“…Family farming systems in Chiapas and the Yucatán Peninsula form the backbone of rural livelihoods, food security, and biocultural heritage (Gómez Martínez et al., 2019; López-Gómez et al., 2023; Fonteyne et al., 2023). et these systems face increasing pressure from climate variability, including irregular rainfall, prolonged droughts, rising temperatures, soil degradation, and biodiversity loss. …”

Crise economique et changements politiques en Indonesie: premiers effets sur le secteur forestier by Sunderlin, William D.

“…The author reviews the likely effects on the forest sector. (1) Decreased demand for Indonesian plywood from main importers (Japan, South Korea and Taiwan) is largely compensated by increased demand from other countries and Malaysia's decision to restrict its wood product exports. (2) Expansion of agriculture will occur partly at the expense of forest cover: spontaneous clearing by farmers, and large scale clearings for agro-industry plantations, mainly oil palm, then cocoa, coffee, rubber trees, pepper, as well as shrimp ponds in mangroves. (3) Transmigration will probably not slow down, foreign aid compensating for the decline of State aid. (4) Unemployed people in the urban sector migrate to rural areas, and young people in the rural areas remain there which may increase pressure on forests for three reasons: a) incentives to expand plantations for export; b) incentives to produce food crops locally (rice, maize, soya) to reduce imports; c) shortage of capital for inputs, that may encourage extensive agriculture. (5) Expansion of mining in forest areas (coal, iron, and nickel) may lead to degradation of important protection forests. (6) The likely slowdown of major road programmes will reduce their direct and indirect impacts on forests. (7) Policy changes as a prerequisite to IMF loans will have negative effects on forest conservation when they encourage plantations for export (oil palms). (8) President Habibie has launched a wave of policy reforms to remedy former abuses in granting timber concessions, and the resulting forest deterioration. …”

Micro watershed to basin scale impacts of widespread adoption of watershed management interventions in Blue Nile Basin by Awulachew, Seleshi Bekele, Tenaw, Mequanint

“…High population pressure, inappropriate agricultural policies, improper land-use planning, over-dependency on agriculture as source of livelihood and extreme dependence on natural resources are inducing deforestation, overgrazing, expansion of agriculture to marginal lands and steep slopes, declining agricultural productivity and resource-use conflicts in many parts of Blue Nile. …”

Synthesis of local knowledge on drivers of tree cover change in the Blue Nile basin by Cronin, M., Lamond, G., Balaguer, F., Venturini, F., Sida, T., Pagella, Tim, Sinclair, Fergus L.

“…The decline of native forest in Jeldu was found to be more rapid than the other two sites, partially due to market pressures from the capital city. Fogera and Diga were found to have remnant native forest still present, although certain tree species had disappeared completely due to over-exploitation for their products. …”

Crossbreeding and intensification of smallholder crop-cattle farming systems in Bhutan by Samdupa, T., Udo, H.M.J., Eilers, C.H.A.M., Ibrahim, Mohamed N.M., Zijpp, A.J. van der

“…Crossbreeding has not reduced cattle numbers per farm, but lactating crossbred cows are mainly stall-fed and, so, crossbreeding reduces grazing pressure on common property resources. Crossbreeding has not yet been able to reduce the gap between supply and demand of dairy products in Bhutan. …”
